Write a quadratic function f whose zeros are -9 & -1
Step-by-step explanation:
This is most easily solved by writing the factored form:
[tex]f(x) = (x + 9)(x + 1)[/tex]
Notice how, if we were to substitute -9 for x, the left part would be -9 + 9 = 0. Since (x + 1) × 0 = 0, this makes the function 0. The same logic applies for the right part.
Final answer:
A quadratic function with zeros at -9 and -1 can be written as f(x) = (x + 9)(x + 1) or f(x) = x^2 + 10x + 9 when expanded.
Explanation:
In mathematics, an expression is a combination of numbers, symbols, and/or operators that represents a mathematical phrase or statement. Expressions can consist of variables, constants, arithmetic operations (such as addition, subtraction, multiplication, and division), exponents, and functions.
To write a quadratic function f with zeros at -9 and -1, we use the fact that a quadratic function f(x) can be represented in the form f(x) = a(x - r1)(x - r2), where r1 and r2 are the zeros of the function and a is a nonzero coefficient. In this case, our zeros are -9 and -1, giving us f(x) = a(x + 9)(x + 1). To keep the function in simplest form, we can choose a = 1, which gives us the quadratic function f(x) = (x + 9)(x + 1) or f(x) = x2 + 10x + 9 after expanding the expression.
Final answer:
A quadratic function with zeros at -9 and -1 can be written as f(x) = (x + 9)(x + 1) or f(x) = x^2 + 10x + 9 when expanded.

What is its constant speed?
Answer:
So the Conclusion is that 4000 km/h is the constant speed.
Step-by-step explanation:
Given:
Time (hrs) | Distance (km)
0.5 | 2000
1 | 4000
1.5 | 6000
To Find:
Constant Speed:
Solution:
We know ,
[tex]Speed =\frac{Distance}{Time}[/tex]
For the first case we have
[tex]Speed=\frac{2000}{0.5} =4000\ km/h[/tex]
For the second case we have
[tex]Speed=\frac{4000}{1} =4000\ km/h[/tex]
For the third case we have
[tex]Speed=\frac{6000}{1.5} =4000\ km/h[/tex]
So the Conclusion is that 4000 km/h is the constant speed
Find the minimum or maximum value of f(x) = x2 + 6x +11 .
Answer:
Therefore the Minimum value of f(x) is 2.
Step-by-step explanation:
Given:
[tex]f(x)=x^{2} + 6x+11[/tex]
To Find:
minimum or maximum value of f(x)
Solution:
To find minimum or maximum value of f(x)
Step 1 . Find f'(x) and f"(x)
[tex]f(x)=x^{2} + 6x+11[/tex]
Applying Derivative on both the side we get
[tex]f'(x)=\dfrac{d(x^{2})}{dx}+\dfrac{d(6x)}{dx}+\dfrac{d(11)}{dx}[/tex]
[tex]f'(x)=2x+6+0[/tex]
Again Applying Derivative on both the side we get
[tex]f''(x)=\dfrac{d(2x)}{dx}+\dfrac{d(6)}{dx}[/tex]
[tex]f''(x)=2[/tex]
Step 2. For Maximum or Minimum f'(x) = 0 to find 'x'
[tex]2x+6=0\\\\2x=-6\\\\x=\dfrac{-6}{2}=-3[/tex]
Step 3. IF f"(x) > 0 then f(x) is f(x) is Minimum at x
IFf"(x) < 0 then f(x) is f(x) is Maximum at x
Step 4. We have
[tex]f''(x)=2[/tex]
Which is grater than zero
then f(x) is Minimum at x= -3
Therefore the Minimum value of f(x) is 2.
The minimum value is 2 when x = -3.
The minimum or maximum value of the function f(x) = x^2 + 6x +11, we need to complete the square or use the vertex formula for a quadratic function.
The function is a parabola that opens upwards (since the coefficient of the x2 term is positive). To complete the square, we group the x-terms and add and subtract the square of half the coefficient of x:
f(x) = (x^2 + 6x + 9) + 11 - 9
f(x) = (x + 3)^2 + 2
The minimum value of this parabola occurs at the vertex, which is (-3, 2).
Triangle SQT is isosceles. The measure of angle STQ is 48°. Triangle S Q T is cut by perpendicular bisector T R. The lengths of line segments S R and R Q are congruent. Side lengths S T and T Q are congruent. Angles S T R and R T Q are congruent. What is the measure of Angle S T R? 24° 38° 48° 76°
Answer:
[tex]m\angle STR=24^o[/tex]
Step-by-step explanation:
we know that
[tex]m\angle STQ=m\angle STR+m\angle RTQ[/tex] ---> by addition angle postulate
we have
[tex]m\angle STQ=48^o[/tex] ----> given problem
[tex]m\angle STR=m\angle RTQ[/tex] ----> given problem
substitute in the expression above
[tex]48^o=2m\angle STR[/tex]
Divide by 2 both sides

Answer:
[tex]3.5 - 1.4 + 2.9 \\ = 5[/tex]
hope this helps you
Answer:
3.5 - 1.4 + 2.9 = 5
Step-by-step explanation:
3. 5 - 1.4 + 2.9
At first, we will add 3.5 and 2.9 and then we will subtract 1.4 from the sum of 3.5 and 2.9.
So, 3.5 - 1.4 + 2.9
= (3.5 + 2.9) - 1.4
= 6.4 - 1.4
= 5
So, the value of 3.5 - 1.4 + 2.9 is 5.

What does it mean to be a storehouse of value?
O
A. It serves as a valid currency.
O
B. The item is divisible and each unit is worth the same
O
C. Any item that can be traded for another item.
O
D. Any item that maintains its worth over time.
Final answer:
Being a storehouse of value means the item retains its worth over time, allowing it to be saved, stored, and reliably used later as a medium of exchange, like money or other assets with lasting value.
Explanation:
To be a storehouse of value means that the item, such as money, can retain its worth over some time. Unlike goods that may deteriorate, go out of style, or otherwise lose value, a storehouse of value allows individuals to save and store their wealth, retrieving it later with confidence that it will still be valuable.
Money is a common store of value since you do not need to spend it right away and can trust that even with the potential erosion of value due to inflation, it will remain a valid medium for future transactions.
Goods such as houses, artworks, or financial assets are also considered stores of value, but money is distinguished by its liquidity—being readily exchangeable for other goods or services. Although not perfect due to inflation, money's role as a medium of exchange in financial markets and aggregate expenditure makes it a convenient choice for storing value, especially when compared to the barter system.
In conclusion, option D - Any item that maintains its worth over time, accurately describes a storehouse of value.
A new pair if shoes will cost you $86 if you buy them on black friday. They will be dicounted 45%. How much will you save if you wait until black Friday
Answer:
saving amount=$38.7
Step-by-step explanation:
given cost price=$86
discount on black friday=45%
selling price=cost price(1-discount%)
selling price=86(1-[tex]\frac{45}{100}[/tex])
selling price=86([tex]\frac{55}{100}[/tex])
selling price=$47.3
saving amount=$86-$47.3=$38.7
saving amount=$38.7 answer
To find the savings on the shoes, multiply the original price by 45% to find the discount amount, then subtract it from the original price. The savings amount to $38.70.
You want to know how much you will save on a new pair of shoes that costs $86 if they are discounted by 45% on Black Friday. To calculate the savings, you need to calculate 45% of the original price and then subtract that amount from the original price.
Step-by-Step Calculation:
Calculate 45% of $86: (0.45 × $86 = $38.70).
Subtract the discount from the original price: ($86 - $38.70 = $47.30).
Therefore, if you wait until Black Friday, you will save $38.70 on the shoes.
mrs jones attended a southern living Home party she purchased a vase which cost $34.99 The shipping charge was three dollars and 8.25% sale tax was paid on the subtotal which included the shipping charge how much did she pay for the vase
The total amount paid for vase is $ 41
Solution:
Given that
Cost of vase = $ 34.99
Shipping charge = 3 dollars
Sales tax = 8.25 % was paid on the subtotal which included the shipping charge
To find: total amount paid for vase
total amount paid for vase = Cost of vase + Shipping charge + sales tax
Let us first find the sales tax
Given that 8.25 % was paid on the subtotal which included the shipping charge
Subtotal = 34.99 + 3 = 37.99
So 8.25 % of 37.99 was paid as sales tax
[tex]\text{ sales tax } = \frac{8.25}{100} \times 37.99 = 3.1341[/tex]
Therefore sales tax amount paid = $ 3.1341
total amount paid for vase = Cost of vase + Shipping charge + sales tax
total amount paid for vase = 34.99 + 3 + 3.1341 = 41.1241 ≈ 41
Therefore total amount paid for vase is $ 41

How many miles could Kenja travel in 1 hour. Is this the same number of hours it takes kenja to travel 1 mile? Explain your answer
Answer:
Kenja could travel a certain number of miles in 1 hour depending the speedometer. So, it is not necessary that she may always take the same number of hours it takes to travel 1 mile.
For example, If Kenja has traveled 120 miles in three hours. It means it would take 5 hours to travel 200 miles. The reason is that her unit rate is 40 miles per hour. So, it would take her 1/40 hours to travel one mile.
Step-by-step explanation:
Kenja could travel a certain number of miles in 1 hour depending the speedometer.
If she is traveling at the rate of 5 miles per hour, it would take her 12 minutes to travel one mile. The only way she can take the same number of hours to travel 1 miles if she travels at the rate of 1 mile per hour.
For example, if Kenja has traveled 120 miles in three hours. It means it would take 5 hours to travel 200 miles. The reason is that her unit rate is 40 miles per hour.
As
[tex]\frac{120}{3} = 40 mph[/tex]
So, if the unit rate is 40 mph, then it would take her 1/40 hours to travel one mile.
So, it is not necessary that she may always take the same number of hours it takes to travel 1 mile.

If f(n) = (2n + 3)2 – 2n, which statement is true?
1. f(3) = 75
2. f(2)= 619
3. f(5) = 16
4. f(-4)= -3
Upon evaluating the function f(n) = (2n + 3)2 – 2n at the given values, the true statement is f(3) = 75.
Explanation:To determine which statement about the function f(n) = (2n + 3)2 – 2n is true, we must evaluate the function at the given values of n.
For f(3), we calculate (2·3 + 3)2 – 2·3 = (6 + 3)2 – 6 = 92 – 6 = 81 – 6 = 75.For f(2), we calculate (2·2 + 3)2 – 2·2 = (4 + 3)2 – 4 = 72 – 4 = 49 – 4 = 45, not 619.For f(5), we calculate (2·5 + 3)2 – 2·5 = (10 + 3)2 – 10 = 132 – 10 = 169 – 10 = 159, not 16.For f(-4), we calculate (2·(-4) + 3)2 – 2·(-4) = (-8 + 3)2 – (-8) = (-5)2 – (-8) = 25 + 8 = 33, not -3.Therefore, the statement that is true is f(3) = 75.

Again, the other machine can print 200 T-shirts in 150 minutes.
So, in one minute the other machine can print [tex]\frac{200}{150} = 1.33[/tex] T-shirts.
Therefore, working together for one minute both the machines will print (4 + 1.33) = 5.33 number of T-shirts.
Hence, they will work together and print 200 T-shirts in [tex]\frac{200}{5.33} = 37.5[/tex] minutes. (Answer)
15 people received an email and sent it to 3 different friends each, who in turn each sent it to 2 new people. What percent of the total number of people who received the e-mail are the original 15 people?
The original 15 people are 10% of the total number of people who received the mail.
Step-by-step explanation:
Given,
Number of people who received mail = 15
Mail further sent to 3 more friends;
Number of people who received mail from 15 people = 15*3 = 45 people
Number of people who received mail from 45 people = 45*2 = 90 people
Total number of people = 15+45+90 = 150 people
Now,
Percent of original people = [tex]\frac{Number\ of\ original\ people}{Total\ number\ of\ people}*100[/tex]
Percent of original people = [tex]\frac{15}{150}*100=10\%[/tex]
The original 15 people are 10% of the total number of people who received the mail.
