What do you need help on sir
Answer:
C
Step-by-step explanation:
SA=4*pi*r^2
SA=4*pi*2^2
SA=4*pi*4
SA=16*pi m^2
SA≈50.2654824574
SA≈50.3 m^2
Which is C
Answer:
Slope: 
Y-intercept: 399
Slope-intercept form: 
Step-by-step explanation:
1. The equation in Standard form is given in the problem:
2. Then, to write the equation of the line in slope-intercept form 
, where <em>m</em> is the slope and <em>b</em> is the y-intercept, you must solve for <em>y</em> as you can see below:
3. Therefore, the slope and the y-intercept are:

Answer:
f(x) = x³ - 5x² - 9x + 45
Step-by-step explanation:
Given x = a, x = b are the zeros of a polynomial, then
(x - a), (x - b) are the factors and f(x) is the product of the factors.
Here the zeros are x = - 3, x = 3 and x = 5, thus
(x + 3), (x - 3) and (x - 5) are the factors and
f(x) = (x + 3)(x - 3)(x - 5) ← expand the first pair of factors using FOIL
= (x² - 9)(x - 5) ← distribute
= x³ - 5x² - 9x + 45
