Plot the points (-6,8) and (0,8) on the coordinate plane below.
What is the distance between these two points?
units
The points (-6,8) and (0,8) are coordinate points, and the distance between the points (-6,8) and (0,8) is 6 units
The distance between the two pointsThe points are given as:
A = (-6,8)
B = (0,8)
The distance between the points is calculated using:
[tex]d= \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}[/tex]
So, we have:
[tex]d= \sqrt{(-6 - 0)^2 + (8 -8)^2}[/tex]
Evaluate
d = 6
Hence, the distance between the points (-6,8) and (0,8) is 6 units

A go cart designer wants to build a Go Cart that measures 4 feet in height, 6 feet in width and 8 feet in length. He needs to construct a three - dimensional model of the Go Cart. Which measurements are appropriate for the scale model? a. 2 feet wide, 5 feet long and 2 feet high b. 3 feet wide, 4 feet long and 2 feet high c. 2.5 feet wide, 2 feet long, and 1.5 feet high d. 6 feet wide, 5 feet long and 3 feet high
Answer:
The correct answer is:
3 feet wide, 4 feet long, and 2 feet high (b)
Step-by-step explanation:
The appropriate scale for the model must be equivalent to the scale of the actual design. This means that the variation must be of the same magnitude in the length, height, and width.
Cart design = 4 feet high; 6 feet wide; 8 feet long
Cart design = 4H : 6W : 8L
where H, W, and L are height, width, and length respectively.
since the model of the Go Cart will be lesser than the actual Cart, let us divide the original cart design by the model designs given in the option, anyone that gives us a consistent variation is a right scale. This is done as follows:
a) Model design = 2H : 2W : 5L
dividing the original dimension by the model:
[tex]\frac{4H}{2H} : \frac{6W}{2W} : \frac{8L}{5L} \\= 2 : 3 : 1.6\\[/tex]
since the variations are not the same, this is the wrong model.
b) Model design = 2H : 3W : 4L
[tex]\frac{4H}{2H} : \frac{6W}{3W} : \frac{8L}{4L} \\= 2 : 2 : 2\\[/tex]
variation is the same across the three dimensions, hence this is the right model.
You can go ahead to use the same principle to do the third model, to see what you will get.

time he retires in 50 years. What annual interest rate, compounded annually, will
provide this?
Answer:

[tex]m =\frac{2}{3}[/tex] ---- Slopes of UA and QD
Sides QU and AD have the same slope
Sides UA and QD have the same slope
Step-by-step explanation:

[tex]U = (2, 5)[/tex]
[tex]A = (5, 7)[/tex]
[tex]D = (4, 4)[/tex]

[tex]U = (x_2,y_2)= (2, 5)[/tex]
Slope, m is calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m =\frac{5-7}{2-5}[/tex]
[tex]m =\frac{-2}{-3}[/tex]

Neil's bank offered him a 4.95% interest rate for his mortgage. If he
purchases 3 points, what will his new rate be?
O A. 0.375%
O B. 4.575%
C. 1.75%
O D. 4.375%
Neil's new interest rate after purchasing 3 points would be 7. 95%. The closest option is B. 4.575%.
How to calculate the interest rate?To calculate the new interest rate after purchasing points, we need to know the cost of one point and the number of points purchased.
One point typically costs 1% of the mortgage amount, so three points would cost 3% of the mortgage amount. The cost of the points is usually paid upfront at closing.
Assuming Neil's mortgage amount is $100,000, the cost of 3 points would be:
3% x $100,000 = $3,000
To calculate the new interest rate, we need to add the cost of the points to the original interest rate and then recalculate it as a percentage:
New rate = Original rate + (Cost of points / Mortgage amount)
New rate = 4.95% + ($3,000 / $100,000)
New rate = 4.95% + 3%
New rate = 7.95%
So, Neil's new interest rate after purchasing 3 points would be 7. 95%. The closest option is B. 4.575%.

The amount a hardware store pays for buying nylon rope is represented by the equation y = 0.08x, where 'y' is the price it pays for 'x' feet of rope. The amount the hardware store charges for selling the rope is represented by the graph. Part A What does the slope of the graph show about the hardware store's selling price for the rope?
Answer:
0.025 $/in.
The store bought 300 ft of rope.
1 ft = 12 in.
300 ft * 12 in./ft = 3600 in.
The store bought 3600 inches of rope.
The store sells 40 inches of rope for $1.60. We can find the selling unit price of rope in dollars per inch.
($1.60)/(40 in.) = $0.04/in.
The store sells the rope at a price of $0.04 per inch.
The store sold all the rope at $0.04/in.
3600 in. * $0.04/in. = $144
The store sold all the rope for $144.
The profit was $54 for selling ll the rope.
$144 - $54 = $90
The bought the rope for $90.
The cost is dollars per inch is
($90)/(3600 in.) = 0.025 $/in.
Step-by-step explanation:
The slope tells for every one-foot increase in the amount of rope sold, the hardware store increases the selling price by $0.08.
The slope of the graph represents the rate of change between the hardware store's selling price (y-axis) and the quantity of nylon rope sold (x-axis).
In this case, the slope is given as 0.08.
Interpreting the slope:
A slope of 0.08 means that for each additional foot of nylon rope the hardware store sells (x increases by 1), the selling price (y) increases by $0.08.
This indicates a linear relationship between the quantity of rope sold and the selling price.
In other words, for every one-foot increase in the amount of rope sold, the hardware store increases the selling price by $0.08.
