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.

Step-by-step explanation:
such candles are cylinders.
the volume of a cylinder is
pi×r²×height
the volume of candle 1 is
pi×3.1²×6.3 in³ = pi × 60.543 in³
the volume of candle 2 is
pi×3.9²×3.9 in³ = pi × 59.319 in³

Answer:

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.

The survey of the general public was conducted using a probability-based sample of the adult population by landline and cellular telephone Aug. 15-25, 2014, with a representative sample of 2,002 adults nationwide. The margin of sampling error for results based on all adults is plus or minus 3. 1 percentage points. What is 95% confidence interval for these findings
Answers
Considering the margin of error, it is found that the 95% confidence interval for the percentage of adults who say vaccines should be required is (64.9%, 71.1%).
What is a confidence interval?
It is given by the sample statistic plus/minus the margin of error.
In this problem, 68% of adults say such vaccines should be required, with a margin of error of 3.1%, hence:
68% - 3.1% = 64.9%.
68% + 3.1% = 71.1%.

if the prisms below are similar what is the ratio of the surface area of the smaller prism to the surface area of the larger prism
v=24
v=375
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]

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 toadsFrom 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 functionThe 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 tPart C: The parameters in the linear functionThe 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 tPart D: The appropriate modelWhen 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.

Steps:
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

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.
~
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
