The equation models the (h) height in centimeters after (t) seconds of a weight ttached to the end of a spring that has been stretched and released.
h=7cos(pi/3 t) solve for t.

t = 3 arc cos(h/7)/π

Step-by-step explanation:

The equation h=7cos(pi/3 t) models the (h) height in centimeters after (t) seconds of a weight attached to the end of a spring that has been stretched and released. To solve the equation for t we will solve the equation step by step:

h=7cos(pi/3 t)

Step 1)

Divide both sides by 7

h/7 = 7cos(pi/3 t)/7

Now the equation becomes h/7=cos(pi/3 t)

Step 2)

h/7=cos(pi/3 t)

Now  apply inverse cosine function:

arc cos (h/7) = pi/3 t

Step 3)

t = 3 arc cos(h/7)/pi

Thus t =  3 arc cos(h/7)/pi

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
