Answer:
5.236 units
Step-by-step explanation:
The relation between r, θ and arc length ( l ) is,
l = rθ
l = 1 * 5π / 3
( The value of π = 3.14 approximately )
5π = 5 x 3.14 = 15.7
l = 1 * 5π / 3
= 5π / 3
= 15.7/3
l = 5.236 units
Note : -
Arc length is denoted by " l ".

Find the value of x if the area of the trapezoid is 54.
Answers
Answer:
11
Step-by-step explanation:
area = (side a + side b)/2 times height
side a = (2 times (area ÷ height)) - side b
side a = (2 times (54+6)) - 7
side a = (2 times (9)) - 7
side a = 18 - 7
side a = 11

What are the solutions to the system of equations? y=x2−7x+12y=−x+7
Answers
Answer:
x = 1, y = 6
or
x = 5, y = 2.
Step-by-step explanation:
y=x2−7x+12
y=−x+7
Substitute for y in the first equation:
- x + 7 = x^2 - 7x + 12
x^2 - 7x + x + 12 - 7 = 0
x^2 - 6x + 5 = 0
(x - 1)(x - 5) = 0
x = 1, 5.
When x = 1, y = -1 + 7 = 6.
when x = 5, y = -5+7 = 2.

7. The cost, c(x), for a carriage ride is given by c(x) = 2x + 4, where “x” is the number of minutes. Graph c(x), including the correct axis labels.
Answers
As m is a constant that is applied to x, it has to have something to do with minutes, eliminating A and B. As the constant is 2, it has to have something to with 2, eliminating D, meaning your answer is C. This is because a slope is the rate of change of y in relation to x, so it would be rate of change of y is a (a being your constant, in this case 2) per x. With your case, y is cost and x is minutes, leading to answer choice C.

If r is 1/6 then we'll have 1/4*1/6+7/24.
Firstly we will multiply 1/4 and 1/6 which will give us 1/24.
Then we will add 1/24 and 7/24 which will give us 8/24.

[tex]\frac{10x^2+3}{y^2+4}[/tex]
Step-by-step explanation:
When adding rational numbers, if the denominator is the same you simply keep the denominator (bottom of fraction) as it is and apply the operation given to the numerator ( top of fraction )
So we have [tex]\frac{6x^2+5}{y^2+4} +\frac{4x^2-2}{y^2+4} =\frac{(6x^2+5)+(4x^2-2)}{y^2+4}[/tex]
==> remove parenthesis and apply signs
[tex]\frac{x^2+5+4x^2-2}{y^2+4}[/tex]
==> simplify numerator by combining like terms
[tex]\frac{10x^2+3}{y^2+4}[/tex]
and we are done!
Note:
like terms are terms with the same variable and exponent
An example of like terms are 6x^7 and 3x^7 as they have x as a variable and a power of 7
The like terms being combined here were (6x² and 4x²) and (5 and -2)

How do we write 8x-2y=10 in slope intercept form?
[tex]\blue\textsf{\textbf{\underline{\underline{Answer and Solution:-}}}}[/tex]
First subtract 8x on both sides:-
-2y=10-8x
or
-2y=-8x+10
Now divide by -2 on both sides:-
y=2x-5
This is our equation in slope intercept form.
Good luck.

Answer:
Step-by-step explanation:
so to go forward we input x and get out y, to go backwards ( the inverse) we plug in y and get out x , so just solve the equation for x
f(x) = 8x - 5
remember that f(x) = y
so,
y = 8x - 5
now solve for x
y+5 = 8x
(y+5) / 8 = x
then remember that we want to swap x and y ,
(x+5) / 8 = y
now y = [tex]f^{-1}[/tex](x), it's kinda confusing.
[tex]f^{-1}[/tex](x)= [tex]\frac{x+5}{8}[/tex]
