the radius of a circle is 10.8ft the length of a chord is 12ft what is the approximate distance of the chord from the center of the circle

Answers

Answer 1

Answer:

9.0 ft (nearest tenth)

Step-by-step explanation:

The chord is the base of an isosceles triangle with sides of the radius.

To calculate the approximate distance of the chord from the center of the circle, we need to find the height of this triangle.

[tex]\sf height=\sqrt{s^2-(\frac{b}{2})^2}[/tex]

(where s is the side length and b is the base length of an isosceles triangle)

Given:

s = radius = 10.8 ftb = chord = 12 ft

[tex]\begin{aligned}\implies \sf height & =\sqrt{10.8^2-\left(\frac{12}{2}\right)^2}\\ & = \sqrt{116.64-36}\\ & = \sqrt{80.64}\\ & = 8.979977728...\\ & = 9.0\: \sf ft\:(nearest\:tenth) \end{aligned}[/tex]

Matt wants to start zip line 16 feet high in one tree and end 10 feet high in the other tree is the difference in height sufficient to meet the slope constraint? Use specific numbers from the situation to justify or refute whether Matt’s design meets the slope constraint

Answers

There is no difference in height that is not sufficient to meet the slope constraint if Matt wants to start a zip line 16 feet high in one tree and end 10 feet high in the other tree is the difference in height sufficient to meet the slope constraint.

What is the slope?

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

We know the slope can be evaluated using:

[tex]\rm Slope = \frac{Change \ in \ y \ axis}{Change \ in \ x \ axis}[/tex]

Change in y-axis = difference in height

Change in y-axis = 16 - 10

                            = 10 feet

Change in x-axis = distance between tress

Since the data is not given.

So, the height difference is insufficient to keep the slope constraint.

Thus, there is no difference in height that is not sufficient to meet the slope constraint if Matt wants to start a zip line 16 feet high in one tree and end 10 feet high in the other tree is the difference in height sufficient to meet the slope constraint.

What is the value of x?

Answers

Answer:

Step-by-step explanation:

Sum of all angles of triangle = 180°

15x + 3 + 3x - 1 + 52 = 180

15x + 3x + 3 - 1 + 52= 180

Combine like terms.

   18x + 54 = 180

To find the vlaue of x, we have to islolate x

Step1: Subtract 54 from both sides

          18x = 180 - 54

          18x = 126

Step2: Divide both sides by 18

             x = 126/18

Step-by-step explanation:

To use the elimination method, we make the coefficient of y the same:

But they are already the same just with different signs.

So we add the 2 equations to make equation 3:

5x + y = 4

+    +   =  +

6x - y = 7

Solve for x:

x = 1

Substitute the value of x into either equation 1 or 2 to find y:

y=4-5

y=-1

Answer:

p = 20

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other.

Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtraction

~

Isolate the variable, p, by multiplying 4 to both sides of the equation:

[tex]5 = \frac{p}{4}\\ 5 (* 4) = \frac{p}{4} (* 4)\\ 5 * 4 = p\\p = 20[/tex]

p = 20 is your answer.

~

5 = p/4

You have to put unknowns (p) on 1 side and knowns on other side.

To get p alone you have to move the 4. Since p divides 4, you have to multiple by 4 to cancel it out. BUT Remember if you have to change one side, you have to change other side by same amount too, so the equality stays true. So multiply BOTH sides by 4

4* 5 = (p/4)*4

the 4s on the right side cancel each other because 4/4=1
So,

20 = p

About 50 cane toads were introduced into Australia in 1935 to try to control the population of beetles that destroy sugar cane plants. By 2005, there were an estimated 100,000,000 cane toads in Australia. An exponential function that models the number of female cane toads in Australia t years after 1935 is given by f(t)=50(1.23)t .

a. Write a linear function p that models the number of cane toads in Australia t years after 1935. p(t)=_____
b. Describe the parameters in the exponential function, , in terms of the context of the problem. ____
c. Describe the parameters in the linear function, p , in terms of the context of the problem. ____
Question 4 d. Which model do you think is more appropriate to model the female cane toad population? Use the parameters of the functions to justify your reasoning. Linear or exponential?
Predict the population of female cane toads in Australia in 2000 based on each function. The linear function predicts that there would be ___ female cane toads in 2000. The exponential function predicts that there would be ___ female cane toads in 2000.

Answers

The linear function predicts that there would be 92857146 female cane toads in 2000 while the exponential function predicts that there would be 34898137 female cane toads in 2000.

Part A: The linear model of the number of cane toads

From the question, we have the following points

(t, f(t)) = (0,50) and (70, 100000000)

The linear function is then calculated as:

f(t) = [f(t2) - f(t1)]/[t2 - t1](t - t1) + f(t1)

This gives

f(t) = [100000000 - 50]/[70 - 0](t - 0) + 50

Evaluate

f(t) = 1428570.71t + 50

Hence, the linear function is f(t) = 1428570.71t + 50

Part B: The parameters in the exponential function

The exponential function is given as:

f(t) = 50(1.23)^t

So, the parameters are:

50 represents the initial value1.23 represents the ratet represents the number of years from 1935f(t) represents the number of cane toad in year t

Part C: The parameters in the linear function

The exponential function is calculated as:

f(t) = 1428570.71t + 50

So, the parameters are:

50 represents the initial value1428570.71 represents the ratet represents the number of years from 1935f(t) represents the number of cane toad in year t

Part D: The appropriate model

When the population of an entity is being model, it is best to use the exponential model, because the populations would grow exponentially for some time, and then stop growing at some point

Hence, the more appropriate model is the exponential model.

Part E: The number of female cane toads in 2000

The year 2000 is 65 years from 1935.

So, we have:

t = 65

For the exponential model, we have:

f(t) = 50(1.23)^t

The equation becomes

f(65) = 50(1.23)^65

Evaluate

f(65) = 34898137

For the linear function, we have:

f(t) = 1428570.71t + 50

The equation becomes

f(65) = 1428570.71 * 65 + 50

Evaluate

f(65) = 92857146

This means that. there would be 34898137 female cane toads in 2000 according to the exponential function.

Answers

The ratio between the surfaces areas of the two prisms is equal to 6.25.

How to get the ratio of the surface areas?

The ratio between the volumes of the prisms is:

[tex]R_v = \frac{375 in^3}{24 in^3} = 15.625[/tex]

This number is equal to the cube of the scale of dilation applied to the dimensions of the smaller prism, so the scale factor is:

[tex]\sqrt[3]{15.625} = 2.5[/tex]

And the ratio between the areas should be the square of the scale factor, then we will have that the ratio between the surface areas of the two prisms is:
