What is the distance between the two points? Use
the distance formula:
d= V(x2 – «1)? + (y2 – yı)?
Answer:
[tex]d= 3.61\ units[/tex]
Step-by-step explanation:
The points (missing) from the question are:
-2,1 and -5,3
Required
Evaluate [tex]d= \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex]
In the points given:
[tex](x_1,y_1) = (-2,1)[/tex] and [tex](x_2,y_2) = (-5,3)[/tex]
Substitute these values in [tex]d= \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex]
[tex]d= \sqrt{(-5 - (-2))^2 + (3 - 1)^2[/tex]
[tex]d= \sqrt{(-3)^2 + (2)^2[/tex]
[tex]d= \sqrt{9 + 4[/tex]
[tex]d= \sqrt{13[/tex]
[tex]d= 3.61\ units[/tex] -- approximated

Simplify the expression below
4(2x+8y+9)-3x+40
plz help
Answer:
5x+32y+76
Step-by-step explanation:
First, distribute.
4 x 2x = 8x
4 x 8y = 32y
4 x 9 = 36
Then, combine like terms.
8x - 3x = 5x
36 + 40 = 76
And that leaves 5x+32y+76

If C = x2 + 7 and D = 3x2 - 4x + 3, find an expression that equals 3C + 3D in standard form.
Answer:
The new expression is: 12 x^2 - 12 x+ 30
Step-by-step explanation:
if C = x^2 + 7
and
D = 3 x^2 - 4 x + 3
Then, 3 C + 3 D can be obtained via:
3 ( x^2 + 7 ) + 3 ( 3 x^2 - 4 x + 3 ) = 3 x^2 + 21 + 9 x^2 - 12 x + 9 =
= 12 x^2 - 12 x+ 30
This cylinder is 7 inches tall and has a volume of 63pi in3. what is the area of the cross section
Answer:
area of cross section of cylinder is inch²
Step-by-step explanation:
Given : Cylinder is 7 inch tall and has a volume of inches³.
We have to find the area of cross section of cylinder.
Area of cross section of cylinder =
To find the cross section first find radius.
Given Volume of cylinder = inches³
Also , Volume of cylinder =
Thus,
Divide both side by 7, we get,
On simplifying , we get,
Since, radius has to be positive, thus neglecting negative term.
Thus, radius of cylinder = 3 inch
Thus, area of cross section of cylinder =
area of cross section of cylinder =
Thus, area of cross section of cylinder is inch²

What is the parallel line and slope of a perpendicular like for 3x+5y=4
Answer:
a line parallel has the same slope and different y-intercept, and the slope of the perpendicular line would be -3/5
Step-by-step explanation:
3x + 5y = 4
5y = -3x + 4
y = -3/5x + 4/5
What is the area of the trapezoid?
Answer:
A=78ft
Step-by-step explanation:
The area of a trapezoid is A=(a+b)/2 *h
a=long base
b=short base
h=height
For your trapezoid, it will look like this:
a=15ft
b=11ft
h=6ft
Let's add those into the equation:
A=(15+11)/2 *6
Okay, let's solve it! Using PEMDAS, we know parenthesis are first.
A=26/2 *6
Now we divide!
A=13*6
Multiply! And don't forget to add your unit.
A=78ft

The triangles are similar. Complete the similarity statement
Answer:
ABC
Step-by-step explanation:
Answer:
YZX ~ ABC
Step-by-step explanation:
For Angle Y, there is one curved line, so you must go to the other triangle and find which angle has one curved line too, in this case that is angle A. Then, Angle Z has three curved lines, and in the other triangle, Angle B has three curved lines, so you now have AB, which only leaves C left. So your final answer is ABC.
write the equation of the line that is parallel to y=4x-1 and passes through the point (4.9)
9514 1404 393
Answer:
y = 4x -7
Step-by-step explanation:
Rearranging the slope-intercept for equation, we can find the intercept:
y = mx +b
y -mx = b . . . . . subtract mx
We know the slope of the parallel line is the same as that of the given line (m=4), so we only need to find 'b'.
b = 9 -4(4) = -7
The desired equation is ...
y = mx +b
y = 4x -7
A company rents out 15 food booths and 23 game booths at the county fair. The fee for a food booth is
$150 plus $4 per day. The fee for a game booth is $95 plus $10 per day. The fair lasts for d days, and all the
booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the
company is paid.
The expression is
Answer:
290d + 245
Step-by-step explanation:
Hello! So what you do first is make two equations, then combine them.
For the food booths, the equation would be 15(4d) + 150
For the game booths, the equation would be 23(10d) + 95
Now simplify them.
Food booths: 60d + 150
Game booths: 230d + 95
Next, we combine the two equations to get one equation.
60d + 150 + 230d +95
Simplify even more...
290d + 245
This is going to be your equation. I don't know the number of days the fair went so I can't go any futher on this question. Hope this helps though!
Jordan invests £2100 into his bank account.
He receives 5.1% per year simple interest.
How much will Jordan have after 2 years?
Give your answer to the nearest penny where appropriate.
Answer:
£4414.20
Step-by-step explanation:
Find out how much is 1% of the money invested in his bank account.
100% = 2100
1% = 2100 ÷ 100 = 21
Find out 5.1% which is his interest that he receives every year.
5.1% = 21 x 5.1 = 107.1
Find out how much he receives including interest every year.
2100 + 107.1 = 2207.1
Find out how much he will have after 2 years.
2207.1 x 2 = 4414.2
You do not need to estimate as there isn't an estimated for nearest penny as it has been estimated for you.

Does anyone know this I don’t know what to put
Answer:
110
Step-by-step explanation:
3x+5+2x=180
Step 1: Simplify both sides of the equation.
3x+5+2x=180
(3x+2x)+(5)=180(Combine Like Terms)
5x+5=180
5x+5=180
Step 2: Subtract 5 from both sides.
5x+5−5=180−5
5x=175
Step 3: Divide both sides by 5.
x=35
35*3+5=110
x-1=y what is the answer plz give me the answer
Answer:
X = 0Y = 1First of all, observe that this is a line, since you can rewrite the equation as y−x+1=0 , which follows the pattern of the generic line ax+by+c=0 .
To draw a line you need two of its points, which you can connect.
To find two points, you can plug any value for one variable, and solve for the other.
For example, let's choose
x=0 . The equation becomes
0−1=y , and so y=−1 .
The first point is thus (0,−1).
Then, let's choose
x=1 . The equation becomes 1−1=y , and so y=0 . The first point is thus
(1,0).
Now you only need to draw the points
(0,−1)

Nathan opens a new savings account and makes an initial deposit of $400. If the account earns 2% annual interest, how much interest will he earn in 9 months?
Answer:
He will earn $6 in interest in 9 months.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
[tex]T = E + P[/tex]
Initial deposit of $400.
This means that [tex]P = 400[/tex]
2% annual interest
This means that [tex]I = 0.02[/tex]
How much interest will he earn in 9 months?
An year has 12 months, this means that [tex]t = \frac{9}{12} = \frac{3}{4} = 0.75[/tex]
This is E. So
[tex]E = P*I*t = 400*0.02*0.75 = 6[/tex]
He will earn $6 in interest in 9 months.

Answer:
[tex] \frac{\pi^{c} }{3} [/tex]
Step-by-step explanation:
Measure of the length of an arc of a circle is given as:
[tex]l = \frac{ \theta}{2\pi} \times 2\pi r \\ \\ \pi = \frac{ \theta}{2\pi} \times 2\pi \times 3 \\ \\ 3 \theta = \pi^{c} \\ \\ \theta = \frac{\pi^{c} }{3} \\ [/tex]
