On a number line, the directed line segment from Q to S has endpoints Q at –14 and S at 2. Point R partitions the directed line segment from Q to S in a 3:5 ratio. Which expression correctly uses the formula to find the location of point R?
To find the location of point R on the number line, you can use the formula for finding a point on a line segment given the endpoints and the ratio. In this case, the ratio is 3:5 and the endpoints are -14 and 2.
Explanation:To find the location of point R, you can use the formula for finding a point on a line segment given the endpoints and the ratio. In this case, the formula is:
R = Q + r(QS)
where Q is the starting point, S is the ending point, r is the ratio between Q and S, and QS is the displacement vector from Q to S. In this problem, Q is -14, S is 2, and the ratio is 3:5. So we can substitute these values into the formula and solve:
R = -14 + (3/8)(2 - (-14)) = -14 + (3/8)(16) = -14 + 6 = -8
Therefore, the location of point R is -8 on the number line.

The location of point R is -8. The correct answer is option a. [tex]\frac{3}{3+5}(2-(-14))+(-14)[/tex]
To find the location of point R which partitions the directed line segment from Q to S in a 3:5 ratio, we use the section formula. The formula is:
[tex]R =\frac{m}{m+n}(x_2-x_1)+x_1[/tex]
Here, m = 3 and n = 5, while Q is at [tex]x_1 =[/tex] -14 and S is at [tex]x_2 =[/tex] 2.
Plugging in the values, we have:
[tex]R =\frac{3}{3+5}(2-(-14))+(-14)[/tex][tex]R = \frac{3}{8}(2+14)-14[/tex][tex]R = \frac{3}{8} (16)-14[/tex][tex]R = \frac{48}{8}-14[/tex][tex]R = 6-14[/tex]R = -8Therefore, the location of point R is at -8 on the number line and it is calculated by the expression [tex]R =\frac{3}{3+5}(2-(-14))+(-14)[/tex].

A lawn mower manufacturer incurs a total of $34,816 in overhead costs and $388 per lawn mower in production costs. How many lawn mowers were manufactured if the average cost of production is $660?
Answer:
128 lawn mowers
Step-by-step explanation:
Given,
The overhead cost = $ 34,816,
The cost for one lawn mower = $ 388,
Let x be the number of lawn mowers manufactured,
So, the total cost of x lawn mowers = 34816 + 388x,
Now, if the average cost of x mowers = $ 660,
So, the total cost = 660x
[tex]\implies 660x = 34816 + 388x[/tex]
[tex]660x - 388x = 34816[/tex]
[tex]272x= 34816[/tex]
[tex]\implies x = \frac{34816}{272}=128[/tex]
Hence, 128 lawn mowers were manufactured.

Kenya plans to make a down payment plus monthly payments in order to buy a motorcycle. At one dealer she would pay $2,500 down and $150 each month. At another dealer, she would pay $3,000 down and $125 each month. After how many months would the total amount paid be the same for both dealers? What would that amount be?
Let us say that the total amount paid in the first dealer is P1 and the total amount paid to the second dealer is P2. So that:
P1 = 2500 + 150 t
P2 = 3000 + 125 t
Where t is the total number of months
Now we are asked when the total amount paid would be equal for the two dealers, this means P1 = P2, therefore equating the two:
2500 + 150 t = 3000 + 125 t
25 t = 500
t = 20 months
Therefore the total amount paid for both dealers would be equal after 20 months.

Find the simple interest paid for 8 years on a $850 loan at 7.5% per year.
The simple interest paid for 8 years on a $850 loan at a 7.5% annual interest rate is $510.
To calculate simple interest, you can use the formula:
Simple Interest (SI) = Principal (P) × Rate (R) × Time (T)
Where:
- Principal (P) is the initial amount of the loan.
- Rate (R) is the annual interest rate (in decimal form).
- Time (T) is the number of years.
In this case:
- Principal (P) = $850
- Rate (R) = 7.5% = 0.075 (decimal form)
- Time (T) = 8 years
Now, plug these values into the formula:
SI = $850 × 0.075 × 8
SI = $510
The simple interest paid for 8 years on a $850 loan at a 7.5% annual interest rate is $510.

Answer:
Option b. width = 16.5 inches and length = 24 inches
Step-by-step explanation:
Tim enlarged a picture wit a width of 5.5 inches and a length of 8 inches.
He enlarged the picture by a scale factor of 3.
We have to find the new dimensions of the picture.

new length = 3×8 = 24 inches
Therefore, option b. is the answer.
Bradley is returning home from a place that is 2 kilometers away. The function y = 2,000 − 90x represents Bradley's distance from home in meters, y, in relation to the number of minutes he walks, x. Which statements about this function are true?
Final answer:
The function y = 2,000 - 90x shows Bradley's distance from home decreases by 90 meters for every minute walked, starting from 2,000 meters away. The graph of this equation is a straight line with a negative slope, indicating constant speed.
Explanation:
The equation y = 2,000 - 90x represents Bradley's distance from home in meters, y, as a function of the time x in minutes that he walks. This equation is a linear function where the initial value 2,000 meters represents the distance from home at the start, and -90 meters/minute is the rate at which this distance decreases as Bradley walks home. As time increases by 1 minute, the distance from home decreases by 90 meters. This relationship shows that Bradley travels at a constant speed since the slope of the line representing the equation (which is the rate of change of distance with respect to time) is constant.
If we graph this function, we would get a straight line that starts at 2,000 meters on the y-axis when t=0 and has a negative slope of 90. Therefore, the graph shows that as time passes, Bradley gets closer to home at a steady pace. This also reflects that the total distance Bradley would walk is 2,000 meters, and the time it would take for him to return home can be found by setting the function equal to zero and solving for x.

To solve the problem we should know about the Equation of a line and slope of a line.
The equations are (y≤ x+2) and (y< -2x+6).
Given to us
One line is solid and goes through the points (0, 2), and (-2, 0) and is shaded below the line.The other line is dashed, goes through the points (0, 6) and (3, 0), and is shaded below the line. For the first line,Given the points (0, 2), and (-2, 0), therefore,
[tex]x_2=0\\y_2=2\\x_1=-2\\y_2=0[/tex]
Substituting the values in the formula of the slope,
[tex]m=\dfrac{(y_2-y_1)}{(x_2-x_1)}[/tex]
[tex]m=\dfrac{2-0}{0-(-2)} = \dfrac{2}{2} = 1[/tex]
Substitute the value of slope and a point in the formula of line,
[tex]y = mx+c\\y_2 = mx_2+c\\2 = (1)0 +c\\c = 2[/tex]
Thus, the equation of the line is y=x+2, but as given the line is solid and is shaded below the line. therefore,
y≤ x+2
For the Second line,Given the points (0, 6) and (3, 0), therefore,
[tex]x_2=0\\y_2=6\\x_1=3\\y_2=0[/tex]
Substituting the values in the formula of the slope,
[tex]m=\dfrac{(y_2-y_1)}{(x_2-x_1)}[/tex]
[tex]m=\dfrac{6-0}{0-3} = \dfrac{6}{-3} = -2[/tex]
Substitute the value of slope and a point in the formula of line,
[tex]y = mx+c\\y_2 = mx_2+c\\6 = (-2)0 +c\\c = 6[/tex]
Thus, the equation of the line is y=-2x+6, but as given the line is shaded below the line. therefore,
y< -2x+6
Hence, the equations are (y≤ x+2) and (y< -2x+6).

Which describes the translation of f(x) to g(x)?
Answer:
The translation function g(x) is given as:
[tex]g(x)=\dfrac{1}{2^x}+4[/tex]
step-by-step explanation:
The parent function is f(x) and its representation is given as:
[tex]f(x)=\dfrac{1}{2^x}[/tex]
Now the graph g*x) is obtained by translation of the graph f(x) by some units.
Now as the graph of g(x) is a shift of the graph f(x) or the graph g(x) is translated by 4 units upwards.
hence the function g(x) is represented by:
g(x)=f(x)+4.
Hence the translation function g(x) is given as:

From a deck of 52 cards, one card is drawn at random. Match the following subsets with their correct probabilities.
1. P(face card)
2. P(seven of hearts)
3. P(no black)
4. P(king)
5. P(diamond)
Answer:
P(face card)=3/13 P(seven of hearts)=1/52P(no black)=1/2P(king)=1/13P(diamond)=1/4Step-by-step explanation:
We know that there are a total 52 cards out of which:
There are 12 face cards ( 4 kings,4 queen and 4 jack)
There are 4 pack:
13- spades 13- club 13-heart 13-diamond.
Out of which there are 26 black cards( 13 spade and 13 club)
There are 26 red cards( 13 heart and 13 diamond)
Now , we are asked to find the probability of each of the following,
1)
P(face card)
Since there are total 12 face cards out of 52 playing cards.
Hence,
P(face card)=12/52=3/13
2)
P( seven of hearts)
As there is just 1 seven of heart out pf 52 cards.
Hence, P(seven of hearts)=1/52
3)
P(no black)
This means we are asked to find the probability of red card.
As there are 26 red card.
Hence P(no black)=26/52=1/2
4)
P(king)
As there are 4 kings out of 52 cards.
Hence, P(king)=4/52=1/13
5)
P(diamond)
As there are total 13 cards of diamond.
Hence,
P(diamond)=13/52=1/4
