Answer:
We conclude that:
f(a) + 5 = a² + 8a - 5
Step-by-step explanation:
Given
The function is given by
f(x) = x²+8x-10
To determine
f(a)+5
In order to determine f(a)+5, first, we need to determine f(a).
Now substitute x = a in the function f(x) = x²+8x-10
f(a) = (a)² + 8(a) - 10
f(a) = a² + 8a - 10
Thus,
f(a) + 5 = (a² + 8a - 10) + 5
f(a) + 5 = a² + 8a - 5
Therefore, we conclude that:
f(a) + 5 = a² + 8a - 5
Answer:
R = 90
Step-by-step explanation:
Triangles will always equal 180 degrees. If you add 61 + 29 = 90. If two of the three angles already equal 90 degrees, then you would subtract 180 - 90. Therefore, the remaining angle would have to be 90 degrees.
Nothing shows up.. could you type it out?
Answer:
Step-by-step explanation:
Given that for X the amount of credit card debt for U.S. adults under 35, is
having mean as 8724 dollars.
For this point estimate to be unbiased and most accurate we must ensure that
i) The sample represents the population
ii) Samples are drawn at random
iii) Sample sizes are sufficienly large.
Hence we see that C is not right as college students cannot represent the entire population. Tv poll cannot be said to be random since there may be a significant population who was not aware about this poll. A and B are right but B is better with more sample size.
