The slope of the line that passes through the points (5,10) and (2,12) is

Answers

Answer:

m = -2/3; b = 13 1/3

Step-by-step explanation:

ΔX = 2 – 5 = -3

ΔY = 12 – 10 = 2

2/-3 = -2/3

Equation for b:

10 = -(2)/(3) (5)+b\n10 = -3 (1)/(3) +b\n13 (1)/(3) =b

Answer:

-2/3

Step-by-step explanation:

To find the slope, you use rise over run. so 12 - 10 over 2 - 5. That is 2 over negative 3. so negative two thirds. I hope this helps and please mark me brainliest!

A cylinder has a surface area of 1850 square meters and a radius of 9 meters. Estimate the volume of the cylinder to the nearest whole number. How????

Answers

in order to find the volume you need the height. 

Surface area = π r² + base x height or width x length
1850 = 3.14 × 9² + radius × 2 x π x height
1850 = 254.34 + 9 × 2 × 3.14 × height
1850 = 310.86 × height

To find the height you have to divide the surface area by the part I bolded

Height = 1850 ÷ 310.56
Height ≈ 6

Volume of a cylinder = πr²×height 
= 3.14 × 9 × 9 × 6
Volume =1526.04

Nearest whole number would be 1526
