Answer:
slope=∆y/∆x=9+5/-4-3=14/-7=-2
Use the formula for the surface area of a right cone:

Where 'r' is the radius and 's' is the slant height, plug in what we know(use 3.14 to approximate for pi):

Multiply and simplify exponent:

Multiply:

Add, round to the nearest whole number:
Answer:
Below.
Step-by-step explanation:
I'll do number 20, 21, 22 for you.
20. It is ±1, ±2, ±4, ±8.
21. Reflected over the x-axis and down 4.
22. Common ratio = 25/5 = 5.
23. Imaginary roots occur in pairs so there is also a root -5i.
The answer is c.
19. Option (a).
This is a translation of 4 to the left ( due to the (x + 4).
4/9
= 0.44444444
= Rounded to 0.44
The correct answer is 0.44
