Answer:
[tex]\frac{q}{360}[/tex] × π10 = 7
Explanation:
The formula to find arc length is [tex]\frac{x}{360}[/tex] × [tex]\pi r^{2}[/tex]
Simply plug in radius and arc length to get your equation.
Answer:
Central angle = 80.21°
Step-by-step explanation:
The arc length in circle is the product of radius and central angle made by the arc in radians.
That is
l = rθ
Here given the values r = 5 ft and l = 7 ft
Substituting
7 = 5 x θ
θ = 1.4 radians
[tex]\theta =1.4\times \frac{180}{\pi }=80.21^0[/tex]
Central angle = 80.21°

Which graphed line represents an equation of a line with a slope of 2 and a point on the line of (1, 2)? A) red line B) blue line C) green line D) purple line
Answer: You've probably already seen the basic method for graphing straight lines; namely, make a T-chart, plot some points, put your ruler against them, and draw the line. But the "nice" form of a straight line's equation (being the slope-intercept form, y = mx + b) can make graphing even simpler and faster.
Step-by-step explanation:
The equation of the line must be 2x - 1
The equation of the line that represents an equation of a line with a slope of 2 and a point on the line of (1, 2) can be written in the form:
[tex]y-y_0=m(x-x_0)[/tex]
m is the slope of the line
(x0, y0) is the point on the line
Substitute the given parameters into the formula to have:
[tex]y-2=2(x-1)\\y - 1= 2x - 2\\y = 2x -2+1\\y = 2x-1[/tex]
Hence the equation of the line must be y= 2x - 1

Jane left the school and started to bike along the road at a rate of 12 mph. Her friend Sally left the school 10 minutes after Jane, biking on the same road at a rate of 15 mph. How long will it take Sally to catch up with Jane?
Answer:
10/3 hours
Step-by-step explanation:
12x=15x-10
12x-15x=15x-10-15x
-3x=-10
-3x/-3=-10/-3
x=10/3
Answer: Sally will catch up with Jane after 50 minutes.
Step-by-step explanation:
Since we have given that
Speed of Jane of biking = 12 mph
After 10 minutes,
Speed of Sally of biking = 15 mph
Let the distance be 'x'.
According to question, our required equation becomes,
[tex]\dfrac{x}{12}-\dfrac{x}{15}=\dfrac{10}{60}\\\\\dfrac{5x-4x}{60}=\dfrac{1}{6}\\\\\dfrac{1x}{60}=\dfrac{1}{6}\\\\x=10\ miles[/tex]
Thus, total distance would be 10 miles.
So, the time taken by Sally to catch up with Jane is given by
[tex]\dfrac{10}{12}=\dfrac{5}{6}\times 60=50\ minutes[/tex]
Hence, Sally will catch up with Jane after 50 minutes.
When -2 is subtracted from a number the result is 8. Find the number. 10 6 -6 -10
Answer:
The number is 6
Step-by-step explanation:
We let the number be x. If we subtract -2 from x we obtain the following result;
x - (-2)
This can be simplified to yield the following result;
x - (-2) = x + 2
we use the rule that negative multiplied by negative yields a positive sign.
We are further informed that the result of the above operation is 8, therefore;
x + 2 = 8
Solving for x yields;
x = 8 -2
x = 6
the number that we are looking for is 6.
The question asks us to find the number that results in 8 when -2 is subtracted from it. To solve this, we can set up an equation. Let x be the number we are looking for:
x - (-2) = 8
We know that in subtraction, we change the sign of the subtracted number and then follow the addition rules. This means our equation becomes:
x + 2 = 8
Now we subtract 2 from both sides to find the value of x:
x = 8 - 2
x = 6
Thus, the number that we are looking for is 6.

if h (r)= 2/3 r - 6, what is the value of h(-9)?
Answer:
[tex]h(-9)=-\frac{2}{33}[/tex]
Step-by-step explanation:
The given expression is [tex]h(r)=\frac{2}{3r-6}[/tex]
We want to find the value of h(-9).
We substitute r=-9 to obtain:
[tex]h(-9)=\frac{2}{3(-9)-6}[/tex]
We multiply out to obtain:
[tex]h(-9)=\frac{2}{-27-6}[/tex]
We simplify the denominator to obtain:
[tex]h(-9)=\frac{2}{-33}[/tex]
This is the same as:
[tex]h(-9)=-\frac{2}{33}[/tex]
The value of h(-9) is 0. Function substitution is a mathematical technique that involves replacing a variable with an expression or function, simplifying calculations and solving equations by making them more manageable.
To find h(-9), you simply substitute -9 for r in the function h(r):
h(-9) = (2/3) * (-9) - 6
Now, calculate it step by step:
h(-9) = (-18/3) - 6
Since -18/3 is -6, the equation simplifies to:
h(-9) = -6 - 6
Now, add -6 and -6:
h(-9) = -12
So, the value of h(-9) is -12.

What is the domain of the function f(x) = x+1 / x2-6x+8
For this case we have that by definition, the domain of a function, is given for all the values for which the function is defined.
We have:
[tex]f (x) = \frac {x + 1} {x ^ 2-6x + 8}[/tex]
The given function is not defined when the denominator is equal to zero. That is to say:
[tex]x ^ 2-6x + 8 = 0[/tex]
To find the roots we factor, we look for two numbers that when multiplied give as a result "8" and when added as a result "-6". These numbers are:
[tex]-4-2 = -6\\-4 * -2 = 8[/tex]
Thus, the factored polynomial is:
[tex](x-4) (x-2) = 0[/tex]
That is to say:
[tex]x_ {1} = 4\\x_ {2} = 2[/tex]
Makes the denominator of the function 0.
Then the domain is given by:
All real numbers, except 2 and 4.

A right triangle with a perimeter 24 has sides of lengths 2x, (2x + 2) and (2x + 4). What is the area of the triangle?
A) 18
B) 21
C) 24
D) 28
Answer:
C) 24
Step-by-step explanation:
1. Since the perimeter of a triangle is the sum of its three sides, you can write the following expression, solve for x and get the value of each side.
[tex]2x+(2x+2)+(2x+4)=24\\2x+2x+2+2x+4=24\\6x+2+4=24\\6x+6=24\\6x=24-6\\6x=18\\x=\frac{18}{6}\\x=3[/tex]
2. So, replacing the value of x, you can calculate the values of each side of the triangle:
First side:
[tex]2x=2(3)=6[/tex]
Second side:
[tex](2x+2)=(2(3)+2)=6+2=8[/tex]
Third side:
[tex](2x+4)=(2(3)+4)=6+4=10[/tex]
As the larger side is the third one, it is the hypotenuse. So, the base and the height.
3. The formula to find the area of the right triangle is given by the expression:
[tex]A=\frac{b*h}{2}[/tex]
Where b is the base and h is the height of the triangle, so replacing the values we found, we have the following:
[tex]A=\frac{8*6}{2}[/tex]
[tex]A=\frac{48}{2}[/tex]
[tex]A=24[/tex]
Therefore the answer is C) 24

bc is along a straight line with section 4 straight lines are 180° if bc is 30° then 180°-30°=150°
Answer:
The measure of ∠4 is 150°
Step-by-step explanation:
Given the figure in which BD is the diameter of circle and
m∠1=100°
m(arc BC)=∠3=30°
we have to find the measure of ∠4.
As BD is a straight line as BD is diameter therefore
∠4 and ∠3 forms a linear pair
⇒ ∠4 and ∠3 are supplementary i.e these angles adds up to 180°
∠4 + ∠3 = 180°
∠4+30°=180°
∠4=180°-30°=150°
Hence, the measure of ∠4 is 150°

Step-by-step explanation:
The dimensions for one wall= 12' by 9'
Area of the wall is given by = width × height
Given width of room = 12' and height of wall =9 feet
Area for one wall= 12×9=108ft²
Area for four walls= 108 × 4=432ft²
Answer:
They will cover 432 feet²
Step-by-step explanation:
* Lets study the information in the problem
- The room has floor with dimensions 12 feet by 12 feet
- The height of the room is 9 feet
- The room has floor and ceiling with same dimensions
- The room has four walls with dimensions 12 feet and 9 feet
- The need to cover the 4 walls
- Each wall shaped a rectangle with base 12 feet and height 9 feet
- The area of the rectangle = base × height
* Now lets solve the problem
∵ The base of the wall = 12 feet
∵ The height of the wall = 9 feet
∵ The area of the wall = base × height
∴ The area of one wall = 12 × 9 = 109 feet²
- The room has four identical walls
∴ The area of the 4 walls = 4 × 108 = 432 feet²
* They will cover 432 feet²

If f(x) = 4x - 1 and g(x) = x^2 , what is (f * g)(x)
Answer:
(f * g)(x) = 4x^3 - x^2
[tex]4x^{3}-x^{2}[/tex]
Step-by-step explanation:
We have been given the following functions;
f(x) = 4x - 1
g(x) = x^2
We are required to determine;
(f * g)(x)
This simply means we shall be finding the product of the two functions given;
(f * g)(x) = f(x)*g(x)
(f * g)(x) = x^2 * (4x - 1 )
we open the brackets by multiplying each term by x^2
(f * g)(x) = x^2(4x) + x^2(-1)
(f * g)(x) = 4x^3 - x^2
