Answer:
9.7%
Step-by-step explanation:
Given:
Observed score value = 8.5
Actual score value = 7.75
Required:
Percent error to the nearest tenth
SOLUTION:
Percent error = \frac{Value_{observed} - Value_{actual}}{Value_{actual} * 100 [/tex]
Percent error = \frac{8.5 - 7.75}{7.75} * 100 [/tex]
Percent error = \frac{0.75}{7.75} * 100 [/tex]
Percent error = \frac{75}{7.75} [/tex]
Percent error = 9.7 [/tex] (nearest tenth)
Answer: they are similar because of the same side lengths
Step-by-step explanation:
Answer:
a). 8(x + a)
b). 8(h + 2x)
Step-by-step explanation:
a). Given function is, f(x) = 8x²
For x = a,
f(a) = 8a²
Now substitute these values in the expression,
= ![\frac{8x^2-8a^2}{x-a}](https://tex.z-dn.net/?f=%5Cfrac%7B8x%5E2-8a%5E2%7D%7Bx-a%7D)
= ![\frac{8(x^2-a^2)}{(x-a)}](https://tex.z-dn.net/?f=%5Cfrac%7B8%28x%5E2-a%5E2%29%7D%7B%28x-a%29%7D)
= ![\frac{8(x-a)(x+a)}{(x-a)}](https://tex.z-dn.net/?f=%5Cfrac%7B8%28x-a%29%28x%2Ba%29%7D%7B%28x-a%29%7D)
= 8(x + a)
b).
= ![\frac{8(x+h)^2-8x^2}{h}](https://tex.z-dn.net/?f=%5Cfrac%7B8%28x%2Bh%29%5E2-8x%5E2%7D%7Bh%7D)
= ![\frac{8(x^2+h^2+2xh)-8x^2}{h}](https://tex.z-dn.net/?f=%5Cfrac%7B8%28x%5E2%2Bh%5E2%2B2xh%29-8x%5E2%7D%7Bh%7D)
= ![\frac{8x^2+8h^2+16xh-8x^2}{h}](https://tex.z-dn.net/?f=%5Cfrac%7B8x%5E2%2B8h%5E2%2B16xh-8x%5E2%7D%7Bh%7D)
= (8h + 16x)
= 8(h + 2x)
