Each side of the patio is ____ feet long.
Answer:
13 feet long
Step-by-step explanation:
Given area of a square patio is 196 square feet.
Length of each side of the patio is the same, since it is a square.
Let a be the length of the side of the square
area=a*a=196
a^2=196
a=√196
a=13 feet

Does anyone know?
Please help meeeee
Answer:
-3
Step-by-step explanation:
each line is decreasing by 3
is 9, 6, 3, 0, -3
x^2– 7x- 18
(Factor the following))
Answer:
(x - 9)(x + 2)
x = 9 or -2
Step-by-step explanation:
First, we need to find factors of 18 that add up to -7
Factors of 18:
1 and 18
2 and 9
3 and 6
Add/Subtract them to have a total sum of -7
18 - 1 = 17 ...... 1 - 18 = -17 (not -7)
9 - 2 = 7 ........ 2 - 9 = -7 (sum of -7)
6 - 3 = 3 ......... 3 - 6 = -3 . (not -7)
Hence the numbers that would go in the brackets would be -9 and 2
(x - 9)(x + 2)
x² - 7x - 18
Answer:
(x-9)(x+2)
Step-by-step explanation:
The first term is the product of two x's being multiplied together. the second term (-7x) is the sum of the two numbers. -18 (the third term) is the product of those numbers.
Think: what two numbers will add up to -7 and multiply to -18
Those numbers are -9 and 2
Now, this is a quadratic trinomial, and you factor these kinds of equations like this: (x+a)(x+b) (a and b as placeholders for actual numbers)
Now, plug -9 and 2 in
(x-9)(x+2)
Hope this helps!

What are the two solutions of the equation x^2 − 10 = 90 ?
Show work :)
Answer:
-10 and 10
Step-by-step explanation:
subtracting what is to the right of the equal sign from both sides of the equation : x^2-10-(90)=0
step 1 - A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
(at the end of step 1 it should look like this) = (x + 10) • (x - 10)
solve as many equations as there are terms in the product
any solution of term = 0 solves product = 0 as well.
Answer:
x = 5 ±√115
Step-by-step explanation:
x² - 10x - 90 = 0
You can solve for x by doing it in 2 ways: Completing the square and by using the quadratic formula
Completing the Square
(x² - 10x + 25) - 25 - 90 = 0
(x - 5)² - 115 = 0
(x - 5)² = 115
x - 5 = ±√115
x = 5 ±√115
Quadratic Formula
√460 = √4 X √115
Hence 2√115

Answer: 12
Step-by-step explanation:
From the question, we are informed that Steve counts up by 4s and Jon counts up by 3s. To get the smallest number that they both say, we have to find the multiple of 3 and 4 and then choose the lowest. This will be:
Multiples of 3 = 3, 6, 9, 12, 15, 18 ...
Multiples of 4 = 4, 8, 12, 16, 20, 24 ....
We can see that the smallest is 12
Answer:
12Step-by-step explanation:

amount financed
Answer:
Sorry, The only one i would possibly know is intrest rate
Step-by-step explanation:

A ball is thrown into the air. The function h=10t-5t^2 can be used to find the height(h) of the ball in meters after t seconds. How long does it take for the ball to reach a height of 5 meters?
Answer: It will take 1 second for the ball to reach a height of 5 meters.
Step-by-step explanation:
Given: The function [tex]h=10t-5t^2[/tex] can be used to find the height(h) of the ball in meters after t seconds.
Now, put h= 5 meters, we get
[tex]5=10t-5t^2[/tex]
[tex]\Rightarrow\ 1=2t-t^2\ \ \[\text{divide both sides by 5}]\\\\\Rightarrow\ t^2-2t+1=0\\\\\Rightarrow(t-1)^2=0\\\\\Rightarrow (t-1)=0\\\\\Rightarrow t=1[/tex]
Hence, it will take 1 second for the ball to reach a height of 5 meters.
Write an equation of the parabola in vertex form.
Answer:
[tex]y= -\frac19(x-3)^2+1[/tex]
Step-by-step explanation:
the x-3 is to shift a normal parabola 3 to the right
the +1 is to lift the top up by one
the -1/9 is to compress and swapt it around
Answer:
y =- [tex]\frac{1}{9}[/tex](x - 3)² + 1
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (3, 1) , thus
y = a(x - 3)² + 1
To find a substitute another point on the graph into the equation
Substitute (1, [tex]\frac{5}{9}[/tex] ) into the equation
[tex]\frac{5}{9}[/tex] = a(1 - 3)² + 1 ( subtract 1 from both sides )
- [tex]\frac{4}{9}[/tex] = 4a ( divide both sides by 4 )
a = - [tex]\frac{1}{9}[/tex]
y = - [tex]\frac{1}{9}[/tex] (x - 3)² + 1 ← equation of parabola in vertex form
