Answer:
The expression would be 8w
Answer:
13in
Step-by-step explanation:
To find the diagonal we use the Pythagorean Theorem:
52+122=x2 where x = hypotenuse
25+144=x2 or x=13in
Answer:
Hey there! The answer is $8.21
Step-by-step explanation:
First, you must multiply the original price, 12.25, by the discount, 33%:
12.25*0.33
≈4.04
Now, subtract this amount from the original price:
12.25-4.04
=8.21
Hope this helps!
Can you take a picture so I can see it
The y value of the vertex is 121.
We can find this by first finding the x value of the vertex. The x value of the vertex in a quadratic equation will always be half way between the two zeros. We can find the zeros by setting each parenthesis equal to 0 and solving for x.
Zero #1
(x + 8) = 0 ---> subtract 8 from both sides.
x = -8
Zero #2
(x - 14) = 0 ----> add 14 to both sides.
x = 14
Since we know that the x value of the vertex must be in the middle of these two, we can take the average of them to find it.
(-8 + 14)/2 = 3
So the x value is 3. Now we can plug that into the equation for all of the x's to get the y value.
f(x) = -(x + 8)(x - 14)
f(3) = -(3 + 8)(3 - 14)
f(3) = -(11)(-11)
f(3) = 121
So the y value is 121.
