Answer:
5.83095 or √34
Step-by-step explanation:
Find the difference between coordinates:
(x2-x1) = (-1 - -4) = 3
(y2-y1) = (-10 - -5) = -5
Square the results and sum them up:
(3)2 + (-5)2 = 9 + 25 = 34
Now Find the square root and that's your result:
Exact solution: √34 = √34
Approximate solution: 5.831
The graph of y= f(x) is shown below. What is the value of f(-3)
The value of the function at x = -3 is -1
What is function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range.
Given that a graph of y= f(x), we need to find f(-3)
The graph tells the value of y when x = -3 is -1
Hence, The value of the function at x = -3 is -1

For a circle of radius 4 feet, find the arc lengeth, S subtened by a central angle of 26 degrees
Answer:
Exact answer = 26π/45 feet.
or we can write it as 1.815 feet to the nearest thousandth.
Step-by-step explanation:
The circumference of the circle = 2*4*π = 8π feet.
So the length of S = (26/360) * 8π
= 26π/45 feet.

Step-by-step explanation:
A painter is painting a rectangular wall that measures 23.6 ft by 19.2 ft. Each gallon can of paint covers 200 square feet. What are the fewest gallons needed to paint the wall?
Answer:
3 gallons
Step-by-step explanation:
Length of the rectangular wall = 23.6 feet
Width of the rectangular wall = 19.2 feet
Surface area of the wall = 23.6 × 19.2
= 453.12 square feet
∵ 200 square feet of the wall is covered by the amount of paint = 1 gallon
∴ 1 square feet of the wall will be covered by the amount of paint = [tex]\frac{1}{200}[/tex] gallons
∴ 453.12 square feet will require the amount of paint = [tex]\frac{453.12}{200}[/tex]
= 2.2656 gallons
Therefore, minimum 3 gallons will be required to paint the wall.

Step-by-step explanation:
Answer:
Distributing
Step-by-step explanation:
The first step is to get the x's out of parenthesis. Distribute the 2 into the (x-4), and the -3 into (x+2).
ex. 2(x-4) = -3(x+2)
distribute: 2x-8= -3x+6
Then solve for x.

Emma receives a large box in the mail.The box is 10cm longer than it wide,and the height is 6 cm more than the width
Answer:
y³+16y²+60y
Step-by-step explanation:
Complete question
Emma receives a large box in the mail. The box is 10cm longer than it wide, and the height is 6 cm more than the width. Find the polynomial function for volume of the box
Let the length be x
Let the width be y
let the height be z
If the box is 10cm longer than it wide, then x = y + 10
Also if the height is 6 cm more than the width,
z = y + 6
Volume of the box = xyz
Substitute
Volume of the box = (y+10)(y)(y+6)
Volume of the box = (y+10)(y²+6y)
Volume of the box = y³+6y²+10y²+60y
Volume of the box = y³+16y²+60y
Hence the required polynomial function is y³+16y²+60y

x= -3, -7
Answer:
x = -7, -3
Step-by-step explanation:
Try to factor the left side of the equation.
(x +7)(x + 3) = 0 Remember that if AB = 0, then A = 0 or B = 0 or both A and B = 0
Therefore, x + 7 = 0 or x + 3 = 0
x = -7 or x = -3
Find the area of this figure.
A = in^2
Answer:
34
Step-by-step explanation:
Answer:
[tex]34in^2[/tex]
Step-by-step explanation:
First, you should find the area of the trapezoid which the formula for that is:
[tex](b1 + b2)h/2[/tex]
So, you will ad up 7in and 3in, and you should get 10in.
Now multiply 10 in by the height which is 5in, so it will be 50in^2. Then you have to divide that by 2 turning it into 25in^2.
For the top part, it is basically a triangle so you just multiply 3 by 6, giving you 18/2 = 9in^2
Add the two together and you should get 34in^2

What is the slope of (1,4) (7,2)
Answer:
3 or 3/1
Step-by-step explanation
the equation for finding the slope when given two coordinate pairs is (y₂ - y₁)/(x₂ - x₁), aka change in y over change in x.
pick one of your coordinate pairs to be y₂ and x₂. it doesn't matter which coordinate pair you choose. the remaining coordinate pair will be your y₁ and x₁.
for this example, i'll use the coordinate pair (7, 2) as my y₂ and x₂ and (1, 4) as my y₁ and x₁.
first, substitute the x-value and y-value from the first coordinate pair.
(y₂ - y₁)/(x₂ - x₁) ⇒ (7 - y₁)/(2 - x₂)
then substitute the y-value and x-value from the remaining coordinate pair.
(7 - y₁)/(2 - x₂) ⇒ (7 - 4)/(2 - 1)
subtract 7 - 4.
(7 - 4)/(2 - 1) ⇒ (3)/(2 - 1)
subtract 2 - 1.
(3)/(2 - 1) ⇒ (3)/(1) or 3/1
simplify.
3/1 ⇒ 3

6/12x - 10 = 30 solve for x
Answer:
x = 80
Step-by-step explanation:
(6/12)*x-10 = 30 // - 30
(6/12)*x-30-10 = 0
1/2*x-40 = 0 // + 40
1/2*x = 40 // : 1/2
x = 40/1/2

Hi there!
x=80
1.Multiply the terms:

2.Divide the fraction term:
[tex]\frac{480}{12}=40[/tex]
3.Subtract the two terms:

Help me work out the equation of the line on this graph. I'll give out the brainiest!
Answer:
y=-1/4x+2
Step-by-step explanation:
The equation would be y=-1/4x+2 because the rise is -1 and the run is 4 (you could also say the run is -4 and the rise is 1. It doesn't really matter). The line also crosses the y axis at 2, which means that 2 is the y-intercept. :)
Answer:
y = (-1/4)x +2
Step-by-step explanation:
Having the actual graph is an easy way to calculate the equation of the line. Since the format is y = mx +b we just need to plug in numbers.
b = y-intercept
m = slope
We can automatically see that the y-intercept is 2, so b = 2. To find the slope we just calculate rise over run. The line is decreasing 1 unit for every 4 units it is "running". Therefore, -1/4 is your slope.
b = 2
m = -1/4
Now, all we need to do is plug in numbers.
y = (-1/4)x +2
Which equation represents the line that is parallel to y=5/2x+31 and passes through (-10,30)?

if 10 shirts cost $80, what is the unit rate (the cost of 1 shirt)?
Answer:
Each shirt is $8
Step-by-step explanation:
80÷10 = 8
Answer:
$8
Step-by-step explanation:
Form your equation, there are 10 shirts at x price, and they equal $80:
10x = $80
solve for x by dividing both sides by 10
10x/10 = $80/10
x = $8
