Triangle P Q R is shown. The length of P Q is 17, the length of Q R is 15, and the length of P R is 14. Law of cosines: a2 = b2 + c2 – 2bccos(A) What is the measure of AngleP to the nearest whole degree? 35° 52° 57° 72°
Answer:
P = 57°
Step-by-step explanation:
Given the following :
PQ = 17
QR = 15
PR = 14
Using the cosine formula since the length of the three sides are given:
a2 = b2 + c2 – 2bccos(A)
To find P:
QR^2 = PQ^2 + PR^2 – 2(PQ)(PR)cos(P)
15^2 = 17^2 + 14^2 – 2(17)(14)cos(P)
225 = 289 + 196 - 476 cosP
476*CosP = 485 - 225
476*CosP = 260
CosP = 260/476
CosP = 0.5462184
P = Cos^-1(0.5462184)
P = 56.892029
P = 57°

A line passes through the point (–1,–2) and is perpendicular to the line with the equation y= –x – 1. What's the equation of the line?
Question 16 options:
A)
y = x – 5
B)
y = –x + 3
C)
y = –x + 7
D)
y = x – 1
Answer:
D) y = x - 1
Step-by-step explanation:
First we need the general equation of point slope form:
(y - y0) = m(x - x0)
Where y0 is the y coordinate and x0 is the x coordinate and m is the slope.
For the line to be perpendicular, we need the slope to be the negated opposite of the other equation. So the negated opposite of -1 is 1.
So our m = 1, y0 = -2, and x0 = -1. Now let's plug this into the equation and reform the equation into slope-intercept form
(y - (-2)) = 1 (x - (-1))
y + 2 = 1 (x + 1)
y + 2 = x + 1
y = x - 1
So the equation of the line that goes through the point (-1,-2) and is perpendicular to the line y = -x -1, is y = x - 1.

Convert the following:
1 meter is equivalent to
ao feet (rounded to the nearest hundredth)
Answer:
1 meter = 3.28 feet
Step-by-step explanation:
The unit of conversion from meters to feet is given as follows;
By convention
1 yard = 09144 meters
1 yard = 3 feet
Therefore, we have;
1 foot = 0.9144/3 = 0.3048 m
Alternatively we can get;
1 inch = 0.0254 meters
1 foot = 12 inches
Therefore, we have;
1 foot = 12 × 0.0254 = 0.3048 meter
Which gives;
1 foot = 0.3048 meter
Given that 0.3048 meter = 1 foot, to find the measure of 1 meter, we proceed by dividing both sides of the equation by 0.3048 to get
0.3048/0.3048 meter = 1/0.3048 foot = 3.28084 feet
1 meter = 3.28084 feet. ≈ 3.28 feet to the nearest hundredth

Answer:
a. You can find the value of 4w by using inverse operations. Subtract 8 from both sides in the equation 4w+8=32. You will get 4w=24. Now, you divide 4 by both sides to get w by itself. You will soon get 6. Now multiply 6 and 4, coming to the conclusion that 4w=24.
b. To find the value of w using the value of 4w, which is 24, simply use inverse operations once more. Using the equation 4w=24, we can use division and divide 4 by both sides, leaving us with w by itself. We end up with w=6. The value of w is 6.
c. You can check if the value of w is correct by plugging in your number back into the equation. Our equation is 4w+8=32, so we replace w with 6, the value for w that we found. We end up with 4(6)+8=32. Multiply 4 by 6, ending up with 24, then add it to 8, coming up with 32. 4(6)+8=32, which shows us that 6 is the correct value for w.

Brooke is evaluating her college credit hours. In order to graduate, Brooke must complete at least 132 credit hours. She has already completed 4 semesters, receiving 15 credit hours per semester. Which inequality could be used to find c, the number of credit hours that Brooke needs to complete in order to graduate college? A. 4(15) + 4c > 132 B. 4(15) + c > 132 C. 4(15) + c < 132 D. 4(15) + 4c < 132
Answer:
B. 4(15) + c > 132Step-by-step explanation:
We already establish an understand that, for Brooke to graduate she needs nothing less than 132 credit hours.
Now a semester has 15 credit hours, she has 4 semester completed already.
Hence 15*4= 60 credit hours done and dusted
This means that she has 132-60 = 72 credit hours to go
Since "c" is the number of credit hours that Brooke needs to complete in order to graduate college.
The inequality can be modeled as,
4(15) + c > 13260 + c > 132
c= 132-60
c= 72

Answer:
f₁(x) = -3x + 2
f₂(x) = x - 4
f₃(x) = x + 8
f₄(x) = -2x - 6
f₅(x) = -3x
Step-by-step explanation:
1). Since function f₁ (blue line) passes through a point (0, 2) and (-2, 8)
Let the equation of the blue line is,
y = mx + b
Since slope of the line 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{8-2}{-2-0}[/tex]
m = -3
Y-intercept 'b' = 2
Therefore, equation of the line will be,
y = -3x + 2
Linear function representing the line will be,
f₁(x) = -3x + 2
2). Let the equation of the red line passing through (0, -4) and (2, -2) is,
y = mx + b
Slope of the line 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{-4+2}{0-2}[/tex]
m = 1
y-intercept 'b' = -4
Therefore, the linear function will be,
f₂(x) = x - 4
3). Let the equation of the green line passing through (-6, 2) and (-2, 6) is,
y = mx + b
Slope of the line 'm' = [tex]\frac{6-2}{-2+6}[/tex]
m = 1
y-intercept 'b' = 8
Therefore, linear function will be,
f₃(x) = x + 8
4). Let the equation of the yellow line passing through (-6, 6) and (-4, 2) is,
y = mx + b
Slope of the line = [tex]\frac{6-2}{-6+4}[/tex]
m = -2
y-intercept of the line 'b' = -6
Therefore, function representing the line will be,
f₄(x) = -2x - 6
5). Let the equation of the pink line is passing through (0, 0) and (-2, 6) is,
y = mx + b
Since the line is passing through origin, y-intercept 'b' = 0
Slope of the line = [tex]\frac{6-0}{-2-0}[/tex]
m = -3
Therefore, equation of the linear function will be,
f₅(x) = -3x

A shipping company borrows $70 million at 5% p.a. compound interest to build a new cruise ship. If it repays the debt after 3 years, how much interest will the company pay?
Answer:
about 11.03 million
Step-by-step explanation:
Use the equation I = P(1+r/100)^n - P (I is the compound interest, P is the principle, r is the rate percent, and n is the number of years):
Substitute the values given:
I = 70,000,000(1 + 5/100)^3 - 70,000,000
Use a calculator to solve and you will get ~11.03 million.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
The interest the company paid is $11 million.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
P = $70 million
r = 5%
t = 3 years
n = 1
A = 70 ( 1 + 0.05)³
A = 70 ( 1.05)³
A = 70 x 1.05 x 1.05 x 1.05
A = $81 million
The amount of interest.
= A - P
= 81 - 70
= $11 million
Thus,.
The interest the company paid is $11 million.

You invest $5000 into an account that has a 2.7% annual interest rate and is compounded quarterly. Approximately how long will it take until you have $7,500 in your account?
Since the interest is compounded, we will have to use the compound interest formula.
We Weill plug 7500 in for A, because that's the amount of money that we want to have at the end of some amount of time.
5000 will go in for P because that's the starting amount.
2.7% will be converted into a decimal percentage form. You can do this by dividing by 100, which you will get .027, and then plug that in for r, the rate.
Since the interest is compounded quarterly, n = 4.
After a bit of number crunching, you will get to the point where you have to solve for an exponent. You can easily do this by using the natural log ln(). One property of logarithm is that you can take the exponent and place it in front of the log. Now you can divide both sides to separate and solve for t.
It take 10.5 years for the investment to grow to $7,500 in the account with a 2.7% annual interest rate compounded quarterly.
Given:
P = $5000
r = 2.7% = 0.027 (as a decimal)
n = 4 (quarterly compounding)
A = $7500
The formula for compound interest:
[tex]\[ A = P\left(1 + \frac{r}{n}\right)^{nt} \][/tex]
Substituting these values into the formula
[tex]\[ 7500 = 5000\left(1 + \dfrac{0.027}{4}\right)^{4t} \][/tex]
Dividing both sides of the equation by $5000, we have:
[tex]1.5 = (1.00675)^{(4t)[/tex]
Assuming a natural logarithm (ln), we have:
ln(1.5) = [tex]ln((1.00675)^{(4t))[/tex]
Using the logarithm property,[tex]ln(a^b) = b * ln(a)[/tex], simplify the equation:
[tex]ln(1.5) = 4t * ln(1.00675)[/tex]
Now, dividing both sides of the equation by 4 * ln(1.00675):
t = ln(1.5) / (4 * ln(1.00675))
t = 10.5 years.
Therefore, it will take 10.5 years for the investment to grow.
