[tex]A=153.86\ cm^2[/tex]

Step-by-step explanation:

we know that

The area of a circle is equal to

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=14/2=7\ cm[/tex] ----> the radius is half the diameter

substitute

[tex]A=(3.14)(7)^{2}=153.86\ cm^2[/tex]

Step-by-step explanation:

While beavers don't 'speak' to trees in human terms, they interact with them by using their teeth to fell trees for food and building materials.

The question, 'what did the beaver say to the tree?', is somewhat humorous due to its anthropomorphic implication of a beaver communicating with a tree in human language. But, from a biological perspective, we could interpret this as asking about the interactions between beavers and trees. Beavers, as known dentition specialists, utilize trees for building dams and lodges and as a source of food. So, if a beaver could 'speak', it might 'tell' the tree that it's hungry, or that it needs materials for its dam. Of course, this is all figuratively speaking.

The initial amount of fish released would be the number shown in the equation.

The answer is 7

Final answer:

The initial number of fish released into the lake is 7, which is calculated by substituting t = 0 into the provided exponential growth function, P(t) = 7bt.

Explanation:

The growth of the fish population in the lake is modeled by the exponential function P(t) = 7bt, where t is the time in weeks after the release, and b is a positive unknown base. To find out how many fish were released initially, we need to consider the population at time t = 0. When we substitute t = 0 into the exponential function, we get P(0) = 7b0, and since any number raised to the power of 0 is 1, P(0) = 7. Therefore, the initial number of fish released was 7.

The solution of the equation is [tex]x=3[/tex] and [tex]y=1[/tex]

Explanation:

The equations are [tex]y=x-2[/tex] and [tex]y=-2 x+7[/tex]

First we shall solve the equation graphically.

The image of the graph is attached below.

This contains the solution to the system of equations.

The equations [tex]y=x-2[/tex] and [tex]y=-2 x+7[/tex] are plotted on the graph.

The intersection of these two equations are the solutions of the system of equations.

Thus, the intersection of the two equations are [tex]x=3[/tex] and [tex]y=1[/tex]

Now, we shall solve the equation algebraically.

Let us solve the equation using substitution method.

Let us substitute [tex]y=x-2[/tex] in [tex]y=-2 x+7[/tex], we get,

[tex]x-2=-2x+7[/tex]

Adding both sides by 2x, we have,

[tex]3x-2=7[/tex]

Adding both sides by 2, we get,

[tex]3x=9[/tex]

Dividing both sides by 3,

[tex]x=3[/tex]

Thus, the value of x is 3.

Substituting [tex]x=3[/tex] in [tex]y=x-2[/tex], we get,

[tex]y=3-2\\y=1[/tex]

Thus, the value of y is 1.

Hence, The solution of the equation is [tex]x=3[/tex] and [tex]y=1[/tex]

The common ratio is 4

Step-by-step explanation:

We need to divide a term by the previous term to find the common ratio in a geometric sequence:

64 ÷ 16 = 4

256 ÷ 64 = 4

By doing it twice we can confirm that the common ratio is 4

Given the following geometric sequence, the common ratio would be 4.

Answer:

The correct step is y = - 5 for, - 4 ≤ x < - 3.

Step-by-step explanation:

From the definition of a box function y = [x], we know that

y = 0 for, 0 ≤ x < 1

y = - 1 for, - 1 ≤ x < 0

y = - 2 for, - 2 ≤ x < - 1

Here, we are given another box function y = [x - 1], and we have to choose from options the steps which is included in the graph of the this function.

So, the correct step is y = - 5 for, - 4 ≤ x < - 3. (Answer)

Answer:

Kayla ran longer miles yesterday than today

Step-by-step explanation:

Distance  Kayla ran  yesterday be x

Then x =   [tex]\frac{9}{10}[/tex] mile

That is  x =  0.9 miles

The Distance she ran today be y

Then y  =  [tex]\frac{8}{9}[/tex]  of the distance she ran yesterday

So the distance Kayla  ran today

=   [tex]\frac{8}{9}[/tex]  [tex]\times \text { the distance she ran yesterday }[/tex]

On substituting the value

y = [tex]\frac{8}{9} \times\frac{9}{10}[/tex]

y = [tex]\frac{8}{10}[/tex]

y = 0.8 miles

x is greater than y

0.9 > 0.8

The best expression represents the value of π is  [tex]\frac{37.7}{12}[/tex] ⇒ 2nd answer

Step-by-step explanation:

π is the ratio between the circumference of the circle and the length of its diameter

[tex]\frac{C}{d}=\pi[/tex] , where

∵ The circumference of the circle is about 37.7 cm

∵ The diameter of the circle is about 12 cm

- Find the ratio between them

∴ [tex]\frac{C}{d}=\frac{37.7}{12}[/tex]

∵ [tex]\frac{C}{d}=\pi[/tex]

- Equate the two right hand sides

∴  [tex]\frac{37.7}{12}=\pi[/tex]

∴ The best expression represents the value of π is  [tex]\frac{37.7}{12}[/tex]

A total of $170.86 will be spent if you buy shirts for $44.11

Step-by-step explanation:

Step 1:

Let the cost of shirts be $x.

Given that, one pair of jeans costs $39.95, 2 pairs cost 2 * $ 39.95 which is $79.9. Jacket costs $45.99.

Step 2:

Create an equation with this given data.

$170.86 = $x + $79.9 + $45.99

Step 3:

Calculate the value of x from this equation to get the cost of shirts.

$170.86 = $x + $125.89

$x = $170.86 - $125.89

$x = $44.11

Answer: Weight is 60

Explanation:

So lets look at what we are given:

w (weight) * 2/3 = 40 pounds

(short explanation is you times 40 by 3/2)

We want to solve for weight there are a few ways to do this but the easiest one is to times both sides of the equation by the reciprocal of 2/3. Which is 3/2. That will cancel our the 2/3 and leave only "w" on the left side.

w = 40 * 3/2

To find the total weight of trail mix used in all bags, more information is needed.

To find the total weight of trail mix used in all bags, we need more information. The information provided in the question does not mention the weight of trail mix or the number of bags. Without this information, we cannot calculate the total weight.

The tall of the tree is 23.048 ft.

Solution:

Given data:

Angular size of a tree =  [tex]\left(\frac{1}{2}\right)^{\circ}[/tex]

Distance = 0.5 miles = 2640 feet

To find the tall of the tree:

Formula to calculate the height of the tree is

[tex]$\text{Physical size}= \text{Angular size}\times\frac{2\pi\times \text{distance}}{360^{\circ}}[/tex]

                    [tex]$ = \left(\frac{1}{2}\right)^{\circ}\times\frac{2\pi\times 2640}{360^{\circ}}[/tex]

                    [tex]$ = \left(\frac{1}{2}\right)^{\circ}\times\frac{44\pi}{3^{\circ}}[/tex]

                    [tex]$ = 23.048[/tex]

Physical size = 23.048 ft

Hence the tall of the tree is 23.048 ft.

x={1,2,3}

Step-by-step explanation:

The given inequality is

[tex]1 \leqslant \frac{6x - 1}{3} \: < \: 7[/tex]

We multiply through by the LCM of 3 to get:

[tex]3\leqslant 6x - 1\: < \: 21[/tex]

We add 1 to both sides to get:

[tex]3 + 1\leqslant 6x \: < \: 21 + 1[/tex]

[tex]4\leqslant 6x \: < \: 22[/tex]

Divide through by 6 to get:

[tex] \frac{4}{6} \leqslant x \: < \: \frac{22}{6} [/tex]

This gives us:

[tex]\frac{2}{3} \leqslant x \: < \: \frac{11}{3} [/tex]

[tex]0.67 \leqslant x \: < \:3.67[/tex]

Since x is an integer, the possible values are:

x={1,2,3}
