Alex

Answer:

h(t) = 1.5t²/2 + 4t +12

Step-by-step explanation:

The growth rate is given by

dh/dt = 1.5t + 4

To determine the height of the seedlings we integrate the rate with respect to t.

The integral of dh/dt = integral of 1.5t + integral of 4

The integral of dh/dt = h

The integral of dh/dt = 1.5t²/2 + 4t

So at t = 0

h = 12

That makes the equation

h = 1.5t²/2 + 4t +12

Where 12 is the constant

So h(t) = 1.5t²/2 + 4t +12

Will give us the height after t years

kherson [118]

Answer:

Step-by-step explanation:

1.C. circumference

2.D. 25.12 decimeters

Solution

C=2πr=2·π·4≈25.13274

3.B. 28.26 meters

Using the formulas

C=2πr

d=2r

Solving for C

C=πd=π·9≈28.27433m

4.B. 25.12 meters

Using the formulas

C=2πr

d=2r

Solving for C

C=πd=π·8≈25.13274m

5.B. 21.98 meters

Using the formulas

C=2πr

d=2r

Solving for C

C=πd=π·7≈21.99115m

A big-screen TV that previously sold for $2,400 has been marked down to $2,040. What is the percent of decrease?
Hitman42 [59]

[~Answer~] (8.):
Heyyy. I'm Avery, and I'm always here to help!

I believe the percent may be 15% ($2,400 - 15% = $2,040)

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

[~Answer Explanation~}:

The percent of the difference is the rate of the difference * 100%

the percent of the difference = .15 * 100% = 15%

since the new price is less than the old price, that is the percent of the decrease.

(See if it'll work): $2,400- 15% = $2,040

And there's your answer <33

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
