Abiologist has been observing a tree’s height. 1414 months into the observation, the tree was 16.1816.18 feet tall. 1818 months into the observation, the tree was 17.0617.06 feet tall.
let x be the number of months passed since the observations started, and let y be the tree’s height at that time. use a linear equation to model the tree’s height as the number of months pass.
a. this line’s slope-intercept equation is
b. 2828 months after the observations started, the tree would be feet in height
c. months after the observation started, the tree would be 26.0826.08 feet tall.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck

step-by-step explanation:

zero

step-by-step explanation:

f(2)= x-2

plug in the 2 in the "x"

f(2)=2-2

f(2)=0
