Last 3 questions thank you so much
Answer:
Step-by-step explanation:
1)
we are given ∠17 and the Adj = 200 meters they want to know the Opp
so use TOA
Tan(17) = Opp / 200
200*Tan(17) = Opp
61.146 = Opp
the mast stands 61.1 meters tall ( rounded to nearest 10th )
2)
now we know the opp = 40 meters and the angle is 35° and Adj = x
Use TOA again, but w/ the different knowns
Tan(35) = 40 / Adj
Adj = 40 / Tan(35)
57.1259 = Adj
so the boat is 57.1 meters from the cliff ( rounded to nearest 10th)
3)
we are given two triangles now and are told to find the difference between them to find the distance between the buoys
Opp = 70
∠A = 60
∠B = 40
we want to find the Adj for each so use TOA
for A , then
Tan(60)= 70/a
a = 70 / Tan(60)
a = 40.4145
for B, then
Tan(40) = 70 /b
b = 70 / Tan(40)
b = 83.4227
so subtract a from b
83.4227 - 40.4145 = 43.008
so from buoy A to buoy B is 43.0 meters ( rounded to nearest 10th )

In 2012 the average cost for a new midsized car was about
$31,000. New car prices tend to go up about 2% every year.
a. What is the multiplier for this situation?
b. If this trend continues, what will the cost be in 4 years?
c. Write an equation to calculate the cost in n years. What does
each of the factors in your equation represent?
Answer:
A) The multiplier for this situation is 0.02.
B) The cost in 4 years will be $ 33,555.39.
C) 31,000 x 1.02 ^ N = X
Step-by-step explanation:
Since in 2012 the average cost for a new midsized car was about $ 31,000, and new car prices tend to go up about 2% every year, to determine what is the multiplier for this situation, what will the cost be in 4 years if this trend continues and to write an equation to calculate the cost in n years the following calculations must be performed:
A)
31,000 x 2/100 = X
31,000 x 0.02 = X
Thus, the multiplier for this situation is 0.02.
B)
31,000 x 1.02 ^ 4 = X
33,555.39 = X
Thus, the cost in 4 years will be $ 33,555.39.
C)
31,000 x 1.02 ^ N = X
Here, N represents the number of years over which the price increase will be calculated, and X represents the price after that number of years.

6. Missing data, nonrandom samples, and outlying observations True or False: If the data for an observation on either the dependent variable or one of the independent variables are missing at random, then the size of the random sample available from the population must be reduced, which reduces the estimator's precision and introduces a bias.
Answer:
False
Step-by-step explanation:
The answer to this question is false because the missing observation does not introduce bias to the estimator. But missing observations reduces the size of the sample that is available from the given population. Therefore reducing the precision of the estimators.
In conclusion, no bias is introduced because of missing observations so the answer is false.
Calculate the area of the figure in square centimeters.
Answer:
20.283
Step-by-step explanation:
1) the formula of the required Area is:
A=A₁+A₂, where A₁ - area of semicircle, A₂ - area of rectangular;
2) the radius of the semicircle is: r=(7-2-1)/2=2 cm, then the area A₁:
A₁=0.5*π*r²=2π≈6.283 (cm²);
3) A₂=7*2=14 (cm²);
4) finally, A=A₁+A₂=6.283+14=20.283 (cm²)

The solution of the graph where the graph of function intersect at
x = 1 and x = 3.642.
What is Function?A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).
We have function,
f(x) = log(x - 1)
g(x) = 1/3x² - 4
As, f(x) = g(x)
log (x-1) = 1/3 x² - 4
Now, putting x= 1, x= 3.642, x= 4.464, x= 4 , x= 0.422 into the formula for the observation.
So, the solution of the graph where the graph of function intersect at
x = 1 and x = 3.642

A local hamburger shop sold a combined total of 390 hamburgers and cheeseburgers on Wednesday. There were 60 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Wednesday?
Answer:
225 hamburgers
Step-by-step explanation:
system of equations:
h + c = 390
c = h-60
use Substitution:
h + h - 60 = 390
2h - 60 = 390
2h = 450
h = 225

What is the equation of line d and c? What is the slope of line d and line c?
Answer:
Step-by-step explanation:
I understand why this was kind tough
the slope of line d is infinite and the slope of line c is zero
so line c 's equation looks like y = 3 ... it's kinda confusing but the line is always 3 so you could pick any x value and y = 3 still. the equation y=3 doesn't rely on x at all to answer it. But x is part of the "frame work" that is implied.
line d is x = 3 , again , y is part of the "frame work" and implied that y doesn't matter in this equations, you always have x = 3 .. or a vertical line , btw. line d does NOT pass the vertical line test , and therefore isn't a function, so the question is wrong, that d will have an equation, b/c there is an implication that d is a function when you say "what is the equation to line d" that is must be a function. But in this case it's not. hm :/ food for thought

Write a function called Radians_To_Degrees which will convert an angle from Radians to Degrees. In your Lesson 06 script: a. convert 1.62 radians to degrees b. Convert pi/9 radians to degrees
Answer:
a) 92.9 degrees
b) 20 degrees
Step-by-step explanation:
Using the conversion factor;
180 degrees = pi radians
For 1.62 radians;
1.62 radians = x
pi radians = 180 degrees
Divide both expressions;
1.62/pi = x/180
pi * x = 1.62 * 180
pi * x = 291.6
x = 291.6/pi
x = 291.6/3.14
x = 92.9 degrees
Hence 1.62 radians is equivalent to 92.9 degrees
b) Recall that
pi radians = 180 degrees
pi/9 rad = y
Cross multiply
y * pi = 180pi/9
y = 180/9
y = 20 degrees
Hence pi/9 radians is equivalent to 20 degrees
