Answers

Answer:

4/6 , 8/12, etc

Step-by-step explanation:

A fraction that can be equivalent to 2/3 is 4/6 or 8/12

This is because if you were to multiply 2/3 by 2/2 you multiplied by the same amount and also the product of that can be simplified to 2/3s.

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.

w = 61❬cos 79.611°, sin 79.611°❭

Answers

Answer:

  w = 61❬cos 280.389°, sin 280.389°❭

Step-by-step explanation:

The "trigonometric form" of a vector is ...

  (magnitude)❬cos(angle), sin(angle)❭

This is sometimes abbreviated ...

  magnitude cis(angle)

__

This form immediately eliminates choices A and D, as those have the trig functions reversed. The signs on the unit vectors i and j tell you the vector has a 4th-quadrant angle, so will be between 270° and 360°. Only answer choice B makes any sense.

  w = 61❬cos 280.389°, sin 280.389°❭

_____

Additional comment

The angle is computed from ...

  θ = arctan(y/x) = arctan(-60/11) = -79.611°

Expressed as a positive angle in the range [0, 360°), that will be ...

  360° +(-79.611°) = 280.389°

__

The abbreviation "cis" is mentioned as an aid to remembering the (x, y) coordinates are the cosine and sine of the angle, in that order.

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:

[tex]2.5^2 = 6.25[/tex]

Answers

[tex]\sf\huge\underline{\star Solution:-}[/tex]

[tex]\rightarrow[/tex] Ratio of two angles are 6:13.

So let's sum up the given angles,

[tex]\rightarrow[/tex] [tex]\sf{222°+81°+6x+13x \:=\: 360°}[/tex]

[tex]\rightarrow[/tex] [tex]\sf{303+19x \:=\: 360°}[/tex]

Solve using the Elimination Method

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

11x = 11

Solve for x:

x = 1

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

I chose 1:

5(1)+y=4

5+y=4

y=4-5

y=-1

Our answer is x=1,y=-1

SOMEONE PLEASE HELP IM SO CONFUSED AND THEIR IS 90 QUESTIONS AND IM ONLY ON 50 AND ITS DUE THIS FRIDAY

Answers

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

Formula for the area of a triangle.
A = B*H/2

Formula for the area of a rectangle.
A = L*W


1. Break up the shape into 1 triangle and 1 rectangle.

2. The length of the rectangle is 8 ft and the width is 3 ft. Plug-in these values into the formula for the area of a rectangle.

A = 8 * 3
A = 24

3. The base of the triangle is 8 ft and the height is 4 ft. Plug-in these values into the formula for the area of a triangle.

A = (8 * 4) / 2
A = 32 / 2
A = 16

4. Now add the two areas together to find the amount of carpet needed.

24 + 16 = 40


Answer:

38 ft²

Step-by-step explanation:

You can take it as combination of two figures, a trapezoid and a triangle.

Trapezoid has bases 12 ft and 8 ft and height 3 ft

Its area is

A = 1/2(8 + 12)(3) = 30 ft²

Triangle has height 4 ft and base 4 ft,

Its area is

A = 1/2(4*4) = 8 ft²

Total area is

30 + 8 = 38 ft²

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.
