Answer:
<STP=105°
Step-by-step explanation:
two interior angles equal one opposite exterior angle therefore
7x+6+7x+1=15x
group like terms
6+1=15x-7-7
7=15x-14x
7=x
for 15x
15 will multiply 7 and that is 105

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.
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 )
:)
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

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)
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.

Consider functions f and g.
f(x) = log(x - 1)
g(x) = 1/3x^2 - 4
Which statement is true about the solutions of the equation f(x) = g(x)?
Answer:[tex]g (f (x)) = 3^{2} + 24[/tex]
Step-by-step explanation:
The true about the solutions of the equation f(x) = g(x) is
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

You are traveling down a country road at a rate of 95 feet/sec when you see a large cow 300 feet in front of you and directly in your lane. The cow is fearless, and staring you down. (Or perhaps she does not understand the gravity of the situation.) Regardless, if you simply hit your brakes, after t seconds, the car will be j(t) = 95t - 9t^2 feet from the point where the brakes were first applied.
1) Must you steer to avoid the cow, or can you rely solely on your brakes? Explain.
2) Graph J(t), j'(t), and j"(t) and Interpret their meanings in context.
3) Is there a time t after which the graphs in part (ii) probably do not accurately model the path of the car?
4) Write a piece-wise function using j(t) that would more accurately model the path of the car on the interval [0, 10], assuming the car did not move after it stopped. Sketch this graph and its derivative.
Answer:
1) You can rely solely on your brakes because when doing so the car will just travel 250ft from the point you hit your brakes till the point the car stopped completely, leaving you 50ft away from the cow.
2) See attached picture.
j(t) represents the distance from the point you hit the brake t seconds after you hit it in feet
j'(t) represents the velocity of the car t seconds after the brakes have been hit in ft/s.
j"(t) represents the acceleration of the car t seconds after the brakes have been hit in [tex]ft/s^{2}[/tex]
3) yes, any time after t=5.28 will not accurately model the path of the car since at that exact time the car will reach a velocity of 0ft/s and unless another force is applied to the car, then the car will not move after that time.
4) [tex]j(t)=\left \{ {{95t-9t^{2}; 0\le t<5.28s} \atop {250.69; 5.28s\leq t \leq 10s}} \right.[/tex]
[tex]j'(t)=\left \{ {{95-18t; 0\leq t<5.28s} \atop {0 ; 5.28s\leq t \leq 10s}} \right.[/tex]
(see attached picture for graph)
Step-by-step explanation:
1) In this part of the problem we need to find the time when the speed of the car is 0. Gets to a complete stop. For this we will need to take the derivative of the position function so we get:
[tex]j(t)=95t-9t^2[/tex]
[tex]j'(t)=95-18t[/tex]
and we set the first derivative equal to zero so we get:
95-18t=0
and solve for t
-18t=-95
[tex]t=\frac{95}{18}[/tex]
t=5.28s
so now we calculate the position of the car after 5.28 seconds, so we get:
[tex]j(5.28)=95(5.28)-9(5.28)^{2}[/tex]
[tex]j(5.28)=250.69ft[/tex]
so we have that the car will stop 250.69ft after he hit the brakes, so there will be about 50ft between the car and the cow when the car stops completely, so he can rely just on the breaks.
2) For answer 2 I take the second derivative of the function so I get:
[tex]j(t)=95t-9t^{2}[/tex]
[tex]j'(t)=95-18t[/tex]
j"(t)=-18
and then we graph them. (See attached picture)
j(t) represents the distance from the point you hit the brake t seconds after you hit it in feet
j'(t) represents the velocity of the car t seconds after the brakes have been hit in ft/s.
j"(t) represents the acceleration of the car t seconds after the brakes have been hit in [tex]ft/s^{2}[/tex]
3) yes, any time after t=5.28 will not accurately model the path of the car since at that exact time the car will reach a velocity of 0ft/s and unless another force is applied to the car, then the car will not move after that time.
4) [tex]j(t)=\left \{ {{95t-9t^{2}; 0\le t<5.28s} \atop {250.69; 5.28s\leq t \leq 10s}} \right.[/tex]
[tex]j'(t)=\left \{ {{95-18t; 0\leq t<5.28s} \atop {0 ; 5.28s\leq t \leq 10s}} \right.[/tex]
