HH represents the height of the tree (in centimeters), t tt years since Renata moved in. H = 210 + 33 t H=210+33tH, equals, 210,

Jet001 [13]

Answer:

Therefore the rate of growth of the tree is 33 cm/ yr.

Step-by-step explanation:

Given that,

The height of the tree is

H= 210 +33t

Here H represent the height of tree in cm and t is time in year.

The rate of growth is the first order derivative of the H with respect to time.

i.e The rate of growth $=\frac{dH}{dt}$

∴H= 210 +33t

Differentiating with respect to t

$\frac{dH}{dt} =0 +33$

$\Rightarrow \frac{dH}{dt}=33$

Therefore the rate of growth of the tree is 33 cm/ yr.

satela [25.4K]

Answer:

B. $45341.60

Step-by-step explanation:

Given:

Initial profit = $37800
Rate of appreciation = 2.3% per year

The equation for this:

$P(t) = 37800*(1 + 0.023)^t = 37800*1.023^t$

Find the value of P(8):

$P(8) = 37800*1.023^8 = 45341.60$

Correct choice is B

Step-by-step explanation:

Cylinder volume formula is $\pi r^2h$

$\pi \times 6^2 \times h=904.78$

$36\pi \times h=904.78$

$h=904.78 \div 36\pi$

$h=78.95695$
