A short-cut to accurately evaluate the given expression above is using a scientific calculator where one can include integrals and evaluate using limits. In this case, using a calculator, the answer is equal to 0.2679. One can verify this by integrating truly letting 1-x^2 as u and use its du to be substituted in the numerator
Answer:
1
Step-by-step explanation:
520 + 480 = 1000 and 480/6 = 80
Step-by-step explanation:
Parent function f(x) = x
g(x)= -3(x-4) + 1
If any number added or subtracted with x then graph moves left or right
Here 4 is subtracted from x, so graph move 4 units to the right
If any number added or subtracted at the end then graph move up or down
Here 1 is added at the end, so graph move 1 unit up.
g(x) = -f(x), for negative sign the graph reflects across x axis
We have negative sign at first, so the graph reflects over x axis
log(4) + log(2) - log(5)
= log(2²) + log(2) - log(5)
= 2 log(2) + log(2) - log(5)
= 3 log(2) - log(5)
= log(2³) - log(5)
= log (2³/5)
= log (8/5)
= log (1.6) = 0.2041... (rounded)
Answer:
C
Step-by-step explanation:
Given
x² + 5x - 36
Consider the factors of the constant term (- 36) which sum to give the coefficient of the x- term (+ 5)
The factors are + 9 and - 4 , since
9 × - 4 = - 36 and 9 - 4 = + 5, thus
x² + 5x - 36 = (x + 9)(x - 4)
Thus (x + 9) is a factor
