Take the deritiivive
it is zero at pi/4 and it repeats at every pi
minimum at where slope goesfrom negative to positive
so at 5pi/4 and 13pi/4 so at every 2pi interval
evaluate origial at 5pi/4
=
=

Answer:
Step-by-step explanation:
6(5x - 2) = -72
30x - 12 = -72
30x = -60
x = -2
answer is A
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, - 6) and (x₂, y₂ ) = (8, - 4) ← 2 points on the line
m = = =
The line crosses the y- axis at (0, - 6 ) ⇒ c = - 6
y = x - 6 → B
Answer:
Base shape of cylinder is Circle
Step-by-step explanation:
A three dimensional curved solid shape which have circular base on the both sides.
Answer:
Step-by-step explanation:
Use the table to find the slope and y-intercept
<u>Find the slope:</u>
- m = (6 - 4)/(3 - 1) = 2/2 = 1
<u>Find b using the pair (1, 4):</u>
- 4 = 1*1 + b
- b = 4 - 1
- b = 3
<u>The line is:</u>
The y-intercept is 3
