Answer:
(-2, 4)
Step-by-step explanation:
Change at least one number in the table so that it DOES represent a function.
Answer:
change 2 to 4
and 1 to 5
1 --> 5
2 --> 10
3 --> 15
4 --> 20
5 --> 24
Step-by-step explanation:
Function means you can have one input for evry one output
so you have to change the 2 and 1 to diffrent numbers like 4 and 5
so now evey imput has their own out put
befor input one it had 5 and 24
and input two had 10 and 20 but changing the number you get one for one
If a circle with a diameter of 4 inches rotates 1000°, what distance will any one spot on
its edge actually travel?
We first convert from degrees to radians multiplying by π/180:
θ = 1000° × π/180 = 17.45 rad
The radius is:
r = d/2 = 4 in /2 = 2 inch
So, The distance traveled is given by the product of the angle in radians and the radius. This is:
d = θr = (17.45 rad)(2 inch) = 34.9 inch
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.

Your subtotal at the store was $58.89. You have a 30% off coupon. If the sales tax rate is 5.5%, what is the total price for your shopping trip?
Answer:
$43.48
Step-by-step explanation:
58.89x.30=17.68
58.89-17.68=41.21
41.21x.055=2.27
41.21+2.27= $43.48
Answer:
$43.49
Step-by-step explanation:
When you take of 30%, multiply by 0.7
When you add 5.5%, multiply by 1.055
Start with $58.89
Take off 30%: 0.7 * $58.89 = $41.22
Add 5.5%: 1.055 * $41.22 = $43.49
Which expression is equivalent to 6(2u)?
(u + 2)6
6 + 2u
(20)6
U + 8
Answer:
There is no answer at all
Given:6(2u)=12u
(u + 2)6=12+6u
6 + 2u= 2u+6
(20)6= 120
U + 8 = u+ 8
Answer:
I would think it should be 6x2u. if u equals 10 then it would be (20)6

I need to know how to graph and use a table to solve for y=3x+0
Answer:
Step-by-step explanation:
On a table, you'd have two columns: one for your input(x) and one for your output(y). If given an x value, put it into the equation to solve for y, and if you have a y value, put it into the equation for x. You can also come up with your own x values and put them into the equation if you need to create a table from scratch I'm not sure what you're asking but this will help you fill in a table. Here's and example for this equation.
X Y
1 3
2 6
3 9
Graphs are pretty simple. Just find a value on the x-axis (horizontal), find the point on the line above or below this value, and look at what number it is for the y value. You can do this backwards if you need to find y when given x.

If we estimate that 10 people can fit in a 5ft by 5ft area, then what would be your estimate of how many people can fit on a basketball court measuring 94ft by 50ft?
Answer:
1,880 people will fit in 94 ft by 50 ft
Step-by-step explanation:
We can estimate this using the area
For 5 ft by 5ft ; 10 people can fit in an area of 5 * 5 = 25 ft^2
In an area of 94 ft by 50 ft, the number of people that can fit will be;
let’s start with the area
Area = 94 * 50 = 4,700 square feet
10 people will fit in 25 square feet
x people in 4,700 square feet
25 * x = 10 * 4700
25x = 47,000
x = 47000/25
x = 1,880 people

Tommy decided to also make a sampler can with a diameter of 2 inches and a height of 3 inches. Tommy calculated that the area of the base was 4 pi inches squared, and multiplied that by the height of 3 inches for a total volume of 12 pi inches cubed. Explain the error Tommy made when calculating the volume of the can.
Answer:
Tommy used diameter instead of radius in calculationStep-by-step explanation:
Givend = 2 inchesh = 3 inchesTo findVolume of the canSolutionVolume formula:
V = πr²hCalculation
V =π(d/2)²h = π(2/2)²(3) = 3π in²Tommy's error is squaring the diameter instead of radius
Answer:
Sample response: Tommy used the diameter instead of the radius in the formula to find the area of the base. The diameter needs to be divided by 2 to find the radius. The correct area of the base is 1 pi square inches. The correct total volume is 3 pi cubic inches.

The freezing point of helium is 0.95 Kelvin. What is this temperature in degrees Fahrenheit?
Answer:
-457.96
Step-by-step explanation:
Step-by-step explanation:
273.15 + °C = K
°C = K - 273.15
0.95K to °C = 0.95 - 273.15 = -272.2°C
°C to °F
(9/5 °C) + 32 = °F
(9/5 × -272.2) + 32 = °F
-489.96 + 32 = °F
= -457.96°F
