Answer:
The slope is 2/5 (0.4).
Step-by-step explanation:
The formula for finding a slope is m = (yB - yA)/(xB - xA). That equation becomes:
m = (9 - 7)/(5 - 0)
Subtract 7 from 9 to get 2.
m = 2/(5 - 0)
Any number subtracted by 0 equals itself.
m = 2/5, or 0.4 is the final answer.

Given the coordinate transformation f(x, y) = (- 2x, y) and the domain (0, 5), (8, - 1) and (- 6, 4) what is the range?
Answer:
{(0, 5), (-16, -1), (12, 4)}
Step-by-step explanation:
Given the coordinate transformation f(x, y) = (- 2x, y) and the domain (0, 5), (8, - 1) and (- 6, 4), to get the range, we will get f(x, y) for all the domain values
For the coordinate (0,5);
f(0, 5) = (-2(0), 5)
f(0, 5) = (0, 5)
For the coordinate (8, -1);
f(8, -1) = (-2(8), -1)
f(8, -1) = (-16, -1)
For the coordinate (-6, 4);
f(-6, 4) = (-2(-6), 4)
f(0, 5) = (12, 4)
Hence the range is {(0, 5), (-16, -1), (12, 4)}

Given the function f(x)=-x^2-5x+12f(x)=−x 2 −5x+12, determine the average rate of change of the function over the interval -5\le x \le 4−5≤x≤4.
Given:
The function is
[tex]f(x)=-x^2-5x+12[/tex]
To find:
The average rate of change of the function over the interval −5 ≤ x ≤ 4.
Solution:
The average rate of change of a function f(x) over the interval [a,b] is
[tex]m=\dfrac{f(b)-f(a)}{b-a}[/tex]
Putting x=-5 in the given function, we get
[tex]f(-5)=-(-5)^2-5(-5)+12[/tex]
[tex]f(-5)=-25+25+12[/tex]
[tex]f(-5)=12[/tex]
Putting x=4 in the given function, we get
[tex]f(4)=-(4)^2-5(4)+12[/tex]
[tex]f(4)=-16-20+12[/tex]
[tex]f(4)=-24[/tex]
Now, the average rate of change of the function over the interval −5 ≤ x ≤ 4 is
[tex]m=\dfrac{f(4)-f(-5)}{4-(-5)}[/tex]
[tex]m=\dfrac{-24-12}{4+5}[/tex]
[tex]m=\dfrac{-36}{9}[/tex]
[tex]m=-4[/tex]
Therefore, the average rate of change of the function over the interval −5 ≤ x ≤ 4 is -4.

a recipe for sparking grape juice calls for 1 1/2 quarts of sparking water and 3/4 quarts of grape juice. how much sparking water would you need to mix with 9 quarts of grape juice?
Answer:
you would need 18 quarts of sparkling water to mix with 9 quarts of grape juice
Step-by-step explanation:
1 1/2 is double of 3/4 so you just need to double 9 quarts of grape juice
Answer:
18 quarts of sparkling water
Step-by-step explanation:
9÷0.75=12 to figure how many times the recipe is multiplied.
12x1.5=18 to figure out how much sparkling water
3/4 = 0.75

Answer:
7/12
Step-by-step explanation:
the least common denominator is 12
4 goes into 12 three times so you multiply both numbers in 3/4 by three
3/4 = 9/12
6 goes into 12 twice so multiply both the 1 and 6 by two
1/6 = 2/12
so the equation becomes 9/12 - 2/12
subtract the numerators
9-2= 7
7/12 can't be simplified any farther so that's the final answer
The price of a washing machine is reduced by 20% for a sale.
Afterwards, the sale price is increased by 30%.
Joachim says
The washing machine is now 10% more expensive than before the sale.
Explain Joachim’s error and work out the correct percentage change in the price of the washing machine from before the sale to after the sale
Answer:
1) Joachim's error is in applying the 30% increase to the initial price of the washing machine, 'x', rather than the reduced price of the washing machine for the sale, which is 0.8·x
2) The correct percentage change in price is 4%
Step-by-step explanation:
The price of the washing machine has the following parameters;
The percentage reduction of the price of the washing machine for a sale = 20%
The percentage by which the price is increased afterwards = 30%
Let 'x' represent the initial selling price of the washing machine before the price decrease, and let 'P' represent the sale price after the price increase, we have;
The price after the 20% reduction = x - 20% × x = x - (20/100) × x = 0.8·x
The price after the 30% increase after the sale = 0.8·x + 30% × 0.8·x = 0.8·x + 30/100 × 0.8×x = 0.8·x + 0.3 × 0.8·x = 1.04·x = x + 0.04·x = x + (4/100) × x = x + 4% × x
Therefore, Joachim's error is in applying the 30% increase to the initial price of the washing machine, 'x', rather than the reduced price of the washing machine for the sale, which is 0.8·x
2) The percentage change in the price after the sale is given as follows;
Price of the washing machine after the sale, P = 1.04·x = (104/100) × x = 104% × x
∴ P = 100%x + 4%x = (100/100)·x + 4%x = x + 4%
The percentage change in price = P - x = x + 4% - x = 4%
The correct percentage change in price = 4%

Carter is going to invest $210 and leave it in an account for 5 years. Assuming the interest is compounded annually, what interest rate, to the nearest tenth of a percent, would be required in order for Carter to end up with $250?
Answer:360
Step-by-step explanation:g-g5
The rate of interest will be 0.35.
What is compound interest?
Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.
Compound interest formula[tex]CI = P(1+\frac{r}{n}) ^{nt} -P[/tex]
and, the Amount is given by
[tex]A = P(1+\frac{r}{n} )^{nt}[/tex]
Where,
A is amount
P is principal
r is rate of interest
n is number of times interest is compounded per year
t is time
According to the given question
Principal, P = $210
Amount, A = $250
Time, t = 5 years
n = 1
Therefore, the interest rate is given by
Amount = [tex]P(1+\frac{r}{n}) ^{nt}[/tex]
⇒[tex]250 = 210(1+\frac{r}{1}) ^{5}[/tex]
⇒[tex]\frac{250}{210} =(1+r)^{5}[/tex]
⇒[tex]1.19 = (1+r)^{5}[/tex]
⇒[tex]\sqrt[5]{1.19} = 1+r\\[/tex]
⇒ 1.035 = 1 + r
⇒ r = 1.035 - 1
⇒ r = 0.35
Hence, the interest rate is o.35.

Please help me with math :C
Answer:
19 feet
Step-by-step explanation:
first, identify which is length and which is width. length is always longer than the width.
in order to do so, we need the measures in the same units, so let's convert . 12 yards to feet and 204 inches to feet:
there are 3 feed in a yard, so let's multiply 12 by 3:
12 • 3 = 36 feet
there are 12 inches in 1 foot, so let's divide 204 by 12
204 ÷ 12 = 17 feet
which is longer? 36 feet! so that's the length
finally, subtract the width(17 ft) from the length (36 ft)
36 - 17 = 19ft

0 degrees
140 degrees
150 degrees
160 degrees
Help?
Answer: 150 degrees
Step-by-step explanation:
The number of degrees did it rotate altogether should be considered as the 150 degrees.
Calculation of the number of degrees:Since A sprinkler rotates 75°, pauses, and then rotates another 75
So, here total degrees be like
= 75 degrees + 75 degrees
= 150 degrees

Step-by-step explanation:
A helicopter landing pad has a length of 80 ft and a width of 50 ft. A safety zone
of uniform width, which is not to be entered during landing, surrounds the landing
pad. The landing pad and safety zone together have a combined area of 10800 ft2,
what is the uniform width (safety zone) around the landing pad?
Answer:
uniform width around the landing pad = 9.41 feet
Step-by-step explanation:
Length of landing pad = 80 ft
width of landing pad = 50 ft
Length of safety zone = (80 + 2w)
width of safety zone = (50 + 2w)
Total area = 10800 [tex]ft^{2}[/tex]
Area of landing pad = length x width
= 80 x 50
= 4000 [tex]ft^{2}[/tex]
Area of landing pad = 4000 [tex]ft^{2}[/tex]
Thus,
area of safety zone = total area - area of landing pad
= 10800 - 4000
= 6800
area of safety zone = 6800 [tex]ft^{2}[/tex]
But,
area of safety zone = length x width
6800 = (80 + 2w) x (50 + 2w)
6800 = 4000 + 160w + 100w + 4[tex]w^{2}[/tex]
divide through by 4,
1700 = [tex]w^{2}[/tex] + 65w + 1000
⇒ [tex]w^{2}[/tex] + 65w + 1000 - 1700 = 0
[tex]w^{2}[/tex] + 65w -700 = 0
Applying the quadratic formula,
w = (-b ± [tex]\sqrt{b^{2} -4ac}[/tex]) ÷ 2a
a = 1, b= 65 and c = -700
w = (-65 ± [tex]\sqrt{(65)^{2}-(4*1*-700) }[/tex]) ÷ 2
= (-65 ± [tex]\sqrt{7025}[/tex]) ÷ 2
= (-65 ± 83.82)÷ 2
w = (-65 + 83.82) ÷ 2 OR (-65 - 83.82) ÷ 2
= 18.82 ÷ 2 OR -148.82 ÷ 2
= 9.41 OR -74.41
Thus, w = 9.41 ft.
