Balloon Elevation 460-
Think About the Process Why is a data point with an
x-coordinate of O a good point to use when creating a trend
line for a data set? The graph shows the altitude of a
weather balloon over time. The trend line passes through the
points (0,436) and (10,342). Write the equation of a trend line
for the data shown in the graph. After how many minutes is
the balloon at an altitude of 351.4 feet above sea level?

Why is a data point with an x-coordinate of 0 a good point to use when creating a trend line for a
data set? Select all that apply.
DA. It is easy to compute the slope using this point.
B. The coordinates of this point are both 0.
C. The y-coordinate of this point is always positive.
D. The y-coordinate of this point is the y-intercept.

step-by-step explanation:

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

so what is the problem what are they asking you to solve

step-by-step explanation:

so what is the problem what are they asking you to solve

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
