Need some help, please. What do I plot? I attempted to figure the questions out many times, but I've come to no clear conclusion, whoops.
Answers
Answer:
vertex is (4,-4) and another point is (6,0) or you could use (2,0) or many other options :)
Step-by-step explanation:
The cool thing about this question your quadratic is in factored form so your x-intercepts are easy to figure out, they are 2 and 6.
So you can plot (6,0) and (2,0).
The vertex will lie half between x=2 and x=6... so it lays at (6+2)/2=4
We just have to find the y-coordinate for when x=4.
Plug in 4 gives you (4-2)(4-6)=(2)(-2)=-4.
So the vertex is at (4,-4).

Answers
Answer:
The equation can be used to find the amount of time Hiroshi spends on his math homework is 1/4 (30 + 60 + x) = x ⇒ answer a
Step-by-step explanation:
* Lets read the problem and take the information to solve the problem
- Hiroshi spends 30 minutes on history homework
- Hiroshi spends 60 minutes on English homework
- Hiroshi spends x minutes on math homework
* From these information
- The total homework time is (30 + 60 + x) minutes
- Hiroshi spends one fourth of his total homework time on math
- The time of math homework is 1/4 the total homework time
∵ The total homework time = (30 + 60 + x)
∵ The time of math homework is 1/4 the total homework time
∴ The time of math homework = 1/4 (30 + 60 + x)
- Then equate the times of math homework
∵ Hiroshi spends x minutes on math homework
∵ The time of math homework = 1/4 (30 + 60 + x)
∴ 1/4 (30 + 60 + x) = x
* The equation can be used to find the amount of time Hiroshi
spends on his math homework is 1/4 (30 + 60 + x) = x
PLEASE HELP ME WITH #4 !!
Answers
Answer:
Step-by-step explanation:
In order to answer all of these questions we need the position function and the acceleration function. We will discuss why when we get there.
The velocity function is given; in order to find the position function we have to take the antiderivative of the velocity function. So in order are the position, velocity, and acceleration functions below:
[tex]s(t)=\frac{1}{3}t^3-\frac{9}{2}t^2+18t+1[/tex]
[tex]v(t)=t^2-9t+18[/tex]
[tex]a(t)=2t-9[/tex]
I know the constant on the position function is 1 because the info given tells me that s(0) = 1.
For the first question, the formula to find the average velocity is as follows:
[tex]v_{avg} =\frac{s(t_{2})-s(t_{1}) }{t_{2}-t_{1} }[/tex]
To find s(t2) and s(t1) we sub in 8 for t2 and 0 for t1 to get the following:
[tex]v_{avg}=\frac{\frac{83}{3}-1 }{8-0}[/tex]
That simplifies to
[tex]v_{avg}=\frac{10}{3}m/sec[/tex]
The second question wants the instantaneous velocity at t = 5. We get this by subbing in a 5 for t in the velocity function:
[tex]v(5)=(5)^2-9(5)+18[/tex] and
v(5) = -2. This means that the velocity of the particle is 2 m/sec, but it is now going in the opposite (or negative) direction.
The third question is asking for the time interval when the particle is moving to the right. On a velocity/time graph, the x's represent the time and the y's represent the velocity. If the "y" values are positive, then the velocity is positive and that means the object is moving to the right. Where the "y" values are negative, that means that the velocity is negative and the object is moving to the left. To find the answer to this problem we think about the positive and negative y values. Because this is a parabola, I know that the places where the graph goes through the x-axis is where the velocity changes from positive to negative and back to positive. In order to find those places where the graph goes through the x-axis I have to factor the velocity function. When I throw that into the quadratic formula on my calculator I get that x = 3 and x = 6. Completing the square on the velocity function gives me a vertex of [tex](\frac{9}{2},-\frac{9}{4})[/tex]
Because the y value of the vertex is negative, that means that the values of x from negative infinity to x = 3 give positive velocity values, between x = 3 and x = 6 the values of the velocity are negative, and from x = 6 to x = positive infinity the velocity is positive again.
So to sum up question 3, the particle is moving to the right on the intervals
(-∞, 3] and [6, ∞)
The fourth question is really tricky. It requires you to remember some of your Physics and how velocity and acceleration vectors are related. If the acceleration and the velocity both have the same sign, whether it be positive or negative, the object is speeding up. If the acceleration and velocity vectors have opposite signs, one positive and one negative, then the object is slowing down. We already know that from negative infinity to 3 the velocity is positive, so let's check the acceleration values in that interval. I only need to test one number, so let's test a(2).
a(2) = 2(2) - 9 and a(2) = -5
-5 means the object is slowing down here since the velocity is positive and the acceleration is negative.
Let's test the interval between 3 and 6. Let's test a(4).
a(4) = -1
Between the interval of 3 and 6 seconds, the velocity is negative. Since the acceleration is also negative, the object is speeding up between the time interval [3, 6].
We already found that from the left of t = 3, the object was slowing down; so it would also be slowing down to the right of t = 6.
Phew! That's it! We're done!

A kilowatt-hour is a unit of measure for consumable energy. A kilowatt-hour, written kWh, is equivalent to using 1,000 watts of power in 1 hour. The table above shows the per-kWh rates charged by several electric companies in New England. According to the United States Energy Information Administration, an average household in New England uses between 530 and 730 kWh of energy per month. Which inequality represents how much less in energy costs a household would pay per month if it uses Company D as its energy supplier, than it uses Company B?

Step-by-step explanation:
We are asked to solve for P using formula [tex]I=Prt[/tex], when [tex]I=5480; r=0.04\text{ and }t=7[/tex].
Upon substituting our given values in simple interest formula, we will get:
[tex]5480=P*0.04*7[/tex]
[tex]5480=P*0.28[/tex]
Switch sides:
[tex]P*0.28=5480[/tex]
Now, we will divide both sides of our given equation by 0.28 as:
[tex]\frac{P*0.28}{0.28}=\frac{5480}{0.28}[/tex]
[tex]P=19571.42857[/tex]
[tex]P\approx 19571.43[/tex]

Answers
Answer:
4b + 5
Step-by-step explanation:
Equation C tells us ...

so, the value "4b +5" can be substituted for "a" in Equation D.
_____
In algebra, things that are equal are interchangeable. One can always be substituted for the other.
the value of 'a' that can be substituted into Equation D to solve the system of equations is 19.
To solve the system of equations given by Equation C: a = 4b + 5 and Equation D: a = 6b \\- 2, we are looking for a value of a which satisfies both equations simultaneously. Since equations C and D both define 'a' in terms of 'b', we can set them equal to each other to find the value of 'b', and then use that value to find 'a'.
Step 1: Set Equation C equal to Equation D, since they both equal 'a'.
4b + 5 = 6b - 2.
Step 2: Solve for 'b'.
Subtract '4b' from both sides: 5 = 2b \\- 2.
Add 2 to both sides: 7 = 2b.
Divide both sides by 2: b = 7/2 or 3.5.
Step 3: Substitute the value of 'b' into either Equation C or D to find 'a'.
Using Equation C: a = 4(3.5) + 5 = 14 + 5 = 19.
Therefore, the value of 'a' that can be substituted into Equation D to solve the system of equations is 19.

A rectangular field measures 81
meters by 117
meters. What will it cost to cover the field with pallets of grass each covering 90 square yards and costing $210
per pallet? (Hint: 1 yd almost equals 0.9 m
)
Answers
Final answer:
To cover a 81 meter by 117 meter field with pallets of grass, we calculate the area in square yards and then the number of pallets needed. Each pallet covers 90 square yards and costs $210. The total cost is $27,300.
Explanation:
The question involves calculating the cost to cover a rectangular field with pallets of grass. The field measures 81 meters by 117 meters. We will first need to calculate the area of the field in square meters and then convert it to square yards since the pallets cover an area in square yards. Then, we'll find out how many pallets are needed and multiply by the cost per pallet to get the total cost.
First, let's find the area of the field in square meters:
Area = length × width = 81 m × 117 m = 9,477 m²
Now, convert square meters to square yards, using the hint that 1 yard ≈ 0.9 meters. Since the area is given in meters and we have that 1 m² = (1/0.9)² yd², we can use:
Area in yd² = 9,477 m² × (1/0.9)² = 9,477 m² × 1.23456790123 yd²/m² ≈ 11,700 yd²
Each pallet of grass covers 90 square yards, so we divide the total area by the coverage per pallet:
Number of pallets = Area in yd² / Coverage per pallet = 11,700 yd² / 90 yd²/pallet ≈ 130 pallets
Finally, we multiply the number of pallets needed by the cost per pallet to get the total cost:
Total cost = Number of pallets × Cost per pallet = 130 × $210 = $27,300
The total cost to cover the field with pallets of grass will be $27,300.
Final answer:
To cover a 81m by 117m field with pallets of grass, you need approximately 130 pallets, resulting in a total cost of $27,300.
Explanation:
The question asks us to calculate the cost to cover a rectangular field with grass pallets. The field's dimensions are 81 meters by 117 meters. First, we need to calculate the field's area in square meters and then convert that area to square yards as the pallet covers a certain number of square yards. Lastly, we will determine the total cost by multiplying the number of pallets needed by the cost per pallet.
To convert the field area from square meters to square yards, we use the approximation given that 1 yard is almost equal to 0.9 meters. So, we have:
Area in square meters = length × width = 81 m × 117 m = 9477 m²Area in square yards = 9477 m² × (1 yd / 0.9 m)² ≈ 9477 × 1.23456790123 yd² ≈ 11700 yd²To find out how many pallets we need:
Number of pallets = Total area in square yards / Area covered by one pallet = 11700 yd² / 90 yd² per pallet ≈ 130 palletsThe cost to cover the entire field is therefore:
Total cost = Number of pallets × Cost per pallet = 130 × $210 = $27,300The cities D, E, and F lie, in respective order, approximately in a straight line. The distance from city D to city E is 125 miles. The distance from city D to city F is 160 miles. Find the distance from city E to city F
Answers
Answer:
35 miles
Step-by-step explanation:
The segment addition theorem tells you ...
DE + EF = DF
125 + EF = 160
EF = 35 . . . . . . . subtract 125
The distance from E to F is about 35 miles.

Answers
Answer:
B
Step-by-step explanation:
h(t)=-4.9t^2+ v_0t+h_0
v_0 represents initial velocity
h_0 represents initial height
we use -4.9 for the coefficient of t^2 because we dealing with meters and seconds
(If it was feet and seconds it would have been -16 instead of -4.9)
Anyways v_0 is 15m/s (We will just put 15 to make it look less complicated)
and from the ground means the initial height was h_0=0
So the answer is B.
