Answer: 5
Step-by-step explanation:
Write the equation of a line that is perpendicular to the graph of y = 1/2 x + 3, and passing through the point (-3, 5). Show work
Answer:
Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.

At Fenway park, they sell 5000 hot dogs at $4 per dog. They also know that for each quarter (25 cents) they raise the price, they will sell 200 less dogs. How many hot dogs should they sell to maximize profit?
Answer:
4,100
Step-by-step explanation:
Let x be increase in the price % and f(x) be revenue
Revenue = Sales price*Total number hot dog sold
Hot dog sold = $4/dog
Now when increase in $0.25. Then, Revenue f(x) = (4+0.25x) (500 - 200x)
f(x) = 2000 - 800x + 1250x - 50x^2
f(x) = -50x^2 + 450x + 2000
To maximize revenue, we have to find f1(x) and find the value of x for which f1(x) = 0
f1(x) = -100x + 450
0 = 0100x + 450
x = 4.5
Hence, to maximize profit number of hot dog they sell: 5000 - 200(4.5)
= 5000 - 900
= 4100
Thus, the number of hot dog sold = 4,100

3(2x - 5) = 9(10 - x)
Answer:
x=7
Step-by-step explanation:
3(2x - 5) = 9(10 - x)
6x-15=90-9x
6x+9x=90+15
15x=105
x=7
Answer:
[tex]x = 7[/tex]
Step-by-step explanation:
First, we need to expand the brackets:
[tex]3(2x-5)=9(10-x)[/tex] (equation given)
[tex]6x-15=90-9x[/tex]
[tex]15x -15 = 90[/tex] (add [tex]9x[/tex] on both sides)
[tex]15x = 105[/tex] (add [tex]15[/tex] on both sides)

5. A line crosses through the points (0, 2) and
(-10, - 16). Which of the following is the slope
of the line?
Answer:
Option B
Step-by-step explanation:
In order to find the answer you must use the formula for slope, substitute the values, and solve.
[tex]P = (0,2) = (x1,y1)[/tex]
[tex]P=(-10,-16)=(x2,y2)[/tex]
[tex]Slope = \frac{y2-y1}{x2-x1}[/tex]
Substitute:
[tex]Slope = \frac{-16-2}{-10-0}[/tex]
Solve:
[tex]-16-2=-16+-2=-18[/tex]
[tex]-10+0=-10[/tex]
[tex]=\frac{-18}{-10}[/tex]
Reduce:
[tex]18\div2=9[/tex]
[tex]10\div2=5[/tex]
Remember that a negative divided by a positive equals a negative
[tex]=-\frac{9}{5}[/tex]

works full time has more than $5,000 in credit card debt?
(A) P(full time and credit card debt over $5,000)
(B) P(full time or credit card debt over $5,000)
(C) P(full time credit card debt over $5,000)
(D) P(credit card debt over $5,000 | full time)
(E) P(full time)*P(credit card debt over $5,000)
Answer:
The correct option is;
(E) P(full time) × P(credit card debt over $5,000)
Step-by-step explanation:
The given parameters are;
The mode of employment of a person = Full time
The amount of debt in the credit card = More than $5,000
The probability that a person works full time = P(full time)
The probability that the person has over $5,000 in credit card debt = P(credit card debt over $5,000)
Therefore, the probability that someone who works full time has more than $5,000 in credit card debt = P(full time) × P(credit card debt over $5,000)

A softball is thrown into the air with an initial velocity of 5 meters per second from a height of 9 meters.
The function below models the distance of the softball from the ground in meters after t seconds.
How many seconds does it take for the softball to hit the ground?
h(t)=4.9t^2+5t+9
Answer:
0.94secs
Step-by-step explanation:
Given the function below that models the distance of the softball from the ground in meters after t seconds expressed as;
h(t)=-4.9t^2+5t+9
The ball hits the ground when the height h(t) is zero
Substitute h(t) = 0 into the expression and calculate the value of t;
0 = -4.9t²+5t+9
Multiply through by 10;
0 = 49t²+50t+90
-49t²+50t+90 = 0
Factorize;
t = -50 ±√50²-4(49)(90)/2(49)
t = -50±√2500+17640/98
t = -50±√20140/98
t = -50+141.92/98
t = 91.92/98
t = 0.94 secs
Hence it takes 0.94secs for the softball to hit the ground

Dan buys a car for £2500.
It depreciates at a rate of 4.2% per year.
How much will it be worth in 4 years?
Give your answer to the nearest penny where appropriate.
Answer:
£2080.00
Step-by-step explanation:
4.2%*4= 16.8%
16.8%*2500= 420
2500-420= 2080
The value of the car after 4 years of depreciation is approximately £2105.80 to the nearest penny.
What is the depreciation rate?The rate of depreciation is the percentage by which the value of an asset decreases over time.
To calculate the value of the car after 4 years, we need to apply the depreciation rate of 4.2% to the original value of £2500 for each year.
First, we can calculate the value of the car after one year:
Value after one year = £2500 - 4.2% of £2500
= £2500 - 0.042 x £2500
= £2500 - £105
= £2395
Then, we can use this value as the starting point to calculate the value after two years,
Value after two years = £2395 - 4.2% of £2395
= £2395 - 0.042 x £2395
= £2395 - £100.29
= £2294.71
Similarly, we can repeat this process for the third and fourth years:
Value after three years = £2198.26
Value after four years = £2105.80
Therefore, the value of the car after 4 years of depreciation is approximately £2105.80 to the nearest penny.

Answer:
Step-by-step explanation:
For this equation you want to start with signing the equation for the best line of fit. You’re going to take your year in and your rabbitsFrom the table and you’re going to find the slope in the Y intercept which would be your MX and you’re B. If you used as most you want to pull up a table in the graphing calculator and into your data there when you get there and the next box under your table you’re going to put y1~mx1+b There it will show you your slope and your intercept along with other things you will need to know for the equation when you get here sleeping when you said you’re going to round to the second decimal place and then you should get y=8.2x-16451.3 Which will be your best line of fit. Now when you’re trying to estimate the number rabbit at the farm In 2016 you want to put your year where X is so you’ll input your 2016 where x is and you should get 8.2(2016)-16451.3From there you solve it and you’re around to the second decimal space and there you have your just wanna sit and your estimate

Answer: See explanation
Step-by-step explanation:
1. What is the 5th term of the arithmetic sequence an= 5n + 1 ?
This will be:
= 5n + 1
= 5(5) + 1
= 25 + 1
= 26
2. What is the next 3 terms of the Fibonacci sequence 0, 1, 1, 2, 3, 5,....
Fibonacci sequence means that you'll add the two previous numbers given to get the next number. Therefore, the next numbers will be:
3+5 = 8
5+8 = 13
8 + 13 = 21
The numbers are 8, 13 and 21.
3. What are the missing numbers in the sequence 4, ---,_,_, 64 ?
a = 4
ar^4 = 64
We replace a with 4
4r^4 = 64
r^4 = 64/4
r^4 = 16
r = 2
2nd term = ar = 4 × 2 = 8
3rd term = ar^2 = 4 × 2^2 = 4 × 4 = 16
4th term = ar^3 = 4 × 2^3 = 4 ×✓8 = 32
The numbers are 8, 16 and 32.
4. What is the common ratio of the given sequence 3, -6, 12,-24, 48 ?
Common ratio = 2nd term / 1st term
= ar / a
= -6/3
= -2
5. What is the 10th term of the arithmetic sequence an = 3n - 5 ?
an = 3n - 5
= 3(10) - 5
= 30 - 5
= 25
6. If a1 = 2, d = -2, then what is a 12?
a12 = a + (n - 1)d
a12 = a + (12 - 1)d
a12 = a + 11d
a12 = 2 + 11(-2)
a12 = 2 - 22
a12 = -20
7. What is the common ratio of the given sequence 1000, 500, 250, 125?
Common ratio = 2nd term / 1st term
= 500 / 1000
= 1/2
8. What is the 8th term of the sequence -10, - 8, -6, -4, ...?
a = -10
d = -8 - (-10) = -8 + 10 = 2
8th term = a + (n - 1)d
= a + (8 - 1)d
= a + 7d
= -10 + 7(2)
= -10 + 14
= 4
9. What is the Khmer greetings?

The stock of Company A gained 2% today to $79.56. What was the opening price of the stock in the beginning of the day?
Answer: $78
Step-by-step explanation:
From the question, we are informed that the stock of Company A gained 2% today to $79.56. The opening price of the stock in the beginning of the day will be calculated as:
= [100% / (100% + 2%)] × 79.56
= (100% / 102%) × 79.56
= 1/1.02 × 79.56
= 79.56/1.02
= 78
Therefore, opening price of the stock in the beginning of the day is $78
