Select the two values of x that are roots of this equation x2+3x-3=0
Answer:
x= (-3i-√3)/2
x= (3i+√3)/2
Step-by-step explanation:
you have to use the quadratic formula which is (-b±√b^2+4ac)/2(a)
a=1
b=3
c= -3
when you plug the numbers into the formula, you get a negative in the square root, so you have to bring out an Imaginary number which is i and connect it with your -b value.
in this case, you only have to switch out the plus and the minus strictly because of the imaginary number

Saniya writes a positive integer on each edge of a square. She also writes at each vertex the product of the numbers on the two edges that meet at that vertex. The sum of the numbers at the vertices is 15. What is the sum of the numbers on the edges of the square?
To solve this problem, we first set up an equation to express the product of the numbers at the vertices of the square in terms of their sum. Then, we use this equation to find the values of the numbers on the edges of the square. The sum of all the numbers on the edges equals to 2 times the square root of 15.
Explanation:Let's denote the four numbers on the edges of the square as a, b, a, b (since it's a square, opposite sides are equal). The products at the vertices are: ab (top left), ab (top right), ab (bottom right) and ab (bottom left).
So the sum of these numbers at the vertices is 4ab = 15. From here, we can solve the equation for ab, giving us ab = 15 / 4.
The problem asks for the sum of the numbers on the edges, which equates to 2a + 2b. As due to our current setup, a = b, we can simplify this to 4a or 4b. But we don't have a or b - we have ab. Because of this, we require a bit of algebra. We know that (a + b)^2 = a^2 + 2ab + b^2. In our case, where a = b, this can simplify to 4a^2. From here, we proceed with ab = 15/4 to replace 2ab in the equation with the latter, and then solve for a^2, followed by a.
The result is a=root(15/4). To get the sum of all the edges, we would then multiply this by 4, giving us 4*root(15/4) = 2root(15).

The sum of the numbers on the sides of the square is calculated by doubling the number on the side 'a', adding to double the number of 'b'. With 'b' equals to 15 divided by four times 'a', the sums equals to 2a plus 2 times 15 divided by four times 'a'.
Explanation:Let's denote the numbers on the sides of the square as a, b, a, b, respectively. Hence, each vertex will be the product of a and b, making each vertex to be ab. Given that the total sum of these vertex is 15, we have 4ab = 15, which simplifies to ab = 15/4.
To find the total sum of the numbers on the sides of the square (the edges), we should sum up all a and b's. Therefore the sum will be 2a + 2b. Given that b = 15 / (4a), we can substitute b into the equation, simplifying to get the total sum = 2a + 2*(15 / (4a)). This is the solution to the problem.

Convert 253 into a hexidecimal
Answer:
0xFD
Step-by-step explanation:
To convert 253 into hexadecimal, divide the number by 16 repeatedly and record the remainders.
Explanation:To convert 253 into hexadecimal, you need to divide the number by 16 repeatedly and record the remainders. The most significant digit of the hexadecimal representation will be the last remainder obtained. So, let's proceed:
253 divided by 16 is 15 with a remainder of 13 (D in hexadecimal).15 divided by 16 is 0 with a remainder of 15 (F in hexadecimal).Therefore, 253 in hexadecimal is DF.
How would I find x, I know it's an isosceles triangle but I so not know how to solve for it?????
Answer:
x=7 (if your teacher cares it could + or - 7)
Step-by-step explanation:
Okay, since it's a 90 degree triangle you can use the Pythagorean theorem
( a^2 + b^2 = c^2)
Since it's an isosceles triangle the other side is x because it's the same value.
x^2 + x^2= (7[tex]\sqrt{2}[/tex] )^2
Add the left side
2x^2= 7^2 + [tex]\sqrt{2}[/tex]^2 roots and square roots cancel each other out
So -> 2x^2= 49 x 2 =98
just solve for x.
x^2 = 98/2
x^2= 49
Square root both sides
x= 7
The number of dogs in a city is declining at a rate of about .08% each
year. If there were 3500 cats to begin with, how many will there be in 10
years?
Answer:
There will be 3472 cats in 10 years
Step-by-step explanation:
There were 3500 cats
The number of dogs in a city is declining at a rate of about 0.08% each year.
We are supposed to find the no. of cats in 10 years
Formula :[tex]N(t)=N_0(1-r)^t[/tex]
Where N(t) = Remaining cats after t days
[tex]N_0[/tex] = Initial population
r = rate of depreciation
t=time
So, No. of cats remained after 10 years = [tex]3500(1-\frac{0.08}{100})^{10}=3472.100[/tex]
Hence There will be 3472 cats in 10 years
Find the equation of the line that passes through point (7,5) and (-9,5)
Answer:
y = 5
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (7, 5) and (x₂, y₂ ) = (- 9, 5)
m = [tex]\frac{5-5}{-9-7}[/tex] = [tex]\frac{0}{-16}[/tex] = 0
This means the line is horizontal and parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (7, 5) and (- 9, 5) with y- coordinates 5, thus
y = 5 ← equation of line

Joe wants to buy a skateboard but he doesn't know if he has enough money. The price of the skateboard is $85 and the sales tax is 6%. What will be the total cost of the skateboard?
Answer:
$90.10
Step-by-step explanation:
price of the skateboard = $85
sales tax = 6%
Dollar value of sales tax = 6% of price of the skateboard
= 6% of $85 = (6/100) * $85 = ( 6* 85)/100 = $ 5.10
Total cost of the skateboard = price of the skateboard + sales tax value
substituting the value of price of the skateboard and sales tax value, calculated above, we have
Total cost of the skateboard = $85 + $ 5.10 = $90.10

Six words have 2 vowels and 2 consonants .How many letters are there in 6 words?How many vowels consonants
Answer:
24, 12, 12
Step-by-step explanation:
I do not understand the question, but I believe you gave us how many vowels and consonants are in a word. Then you asked us for how many of them were in 6 words, which is simple math of 4 times 6. I don't get the last part, but I think you asked how many consonants in 6 words, and how many vowels in six words, another simple math question, 2 times 6.
In the English language, 5 letters are typically considered vowels: a, e, i, o, and u, with 2 additional letters, y, and w, that can sometimes act as vowels or consonants depending on their position in a word. To find out how many vowels and consonants there are in six words, we need more information about the specific six words.
