A gardener is planting two types of trees:
denpristay [2]

It takes 12 years for both trees to be of same height

<em><u>Solution:</u></em>

Assume the year that it would take to these trees have the same height is : x (years)

<em><u>Type A is 7 feet tall and grows at a rate of 23 inches per year:</u></em>

Convert 7 feet to inches

We know that,

1 foot = 12 inch

7 feet = 12 x 7 inch = 84 inch

Thus, type A is 84 inches tall and grows at a rate of 23 inches per year

We can frame a equation as:

Type A = 84 + 23(number of years)

Type A = 84 + 23x ---------- eqn 1

<em><u>Type B is 5 feet tall and grows at a rate of 25 inches per year</u></em>

Convert 5 feet to inches

5 feet = 5 x 12 inches = 60 inches

Thus, type B is 60 inches tall and grows at a rate of 25 inches per year

We can frame a equation as:

Type B = 60 + 25(number of years)

Type B = 60 + 25x --------- eqn 2

For both the trees to be of same height, eqn 1 must be equal to eqn 2

84 + 23x = 60 + 25x

25x - 23x = 84 - 60

2x = 24

x = 12

Thus it takes 12 years for both trees to be of same height

PLEASE HELP!!!! IM SOO CONFUSED
dangina [55]

Answer:

4. 480.38m² 6. 3.35

Step-by-step explanation:

Assuming you're looking for the area of the shaded region, you must first be aware that the entire circle has a 360 angle.

From there. for no. 4:

You subtract 87 from 360 to find the angle of the major arc.

360-87=273

From there you must also know the formula to find the area of a sector which is:

(x/360)×pi×r²

In our case 273 is x and 14.2 is r so

(273/360)×pi×14.2²= 480.38

Do the same steps to find 6

Write an explicit rule in function form for the sequence represented by the given terms.
hram777 [196]

Answer:

The general relation about a geoemtric sequence is

a_{n}=a_{1}r^{n-1}

For the first sequence, we have

3=a_{1}r^{5-1}

147=a_{1}r^{7-1}

Which is a system of equations. We can isolate a variable in the first equation to replace that expression into the second equation.

a_{1}=\frac{3}{r^{4} }

147=\frac{3}{r^{4}  }r^{6}

r^{2}=\frac{147}{3}\\  r=\sqrt[2]{49}\\r=7

Now, we replace this value to find the other one

3=a_{1}(7)^{4}\\ a_{1}=\frac{3}{2401}

Therefore, the explicit rule function is

a_{n}=\frac{3}{2401}  \times (7)^{n-1}

Now, we use the same process for the second sequence.

10=a_{1}r^{3-1}  \\a_{1}=\frac{10}{r^{2} }

The second equation is

1440=a_{1}r^{5-1}\\a_{1}=\frac{1440}{r^{4} }

Now, we solve the following expression

\frac{10}{r^{2} }=\frac{1440}{r^{4} }

We solve for r

\frac{r^{4} }{r^{2} }=\frac{1440}{10}\\r^{2}=144\\ r=\sqrt{144} \\r=12

Then

a_{1}=\frac{10}{(12)^{2} }  =\frac{10}{144}=\frac{5}{72}

Therefore, the function that models the second sequence is

a_{n}=\frac{5}{72} \times (12)^{n-1}

Notice that a_{n} is the dependent variable and n is the independent variable.
