Answer:
78.5 inch²
Step-by-step explanation:
Given
diameter (d) = 10 inches
radius (r) = 10 / 2 = 5 inches
Area of circle
= πr²
= 3.14 * ( 5)²
= 3.14 * 25
= 78.5 inch²

Answer:
x = 1
Step-by-step explanation:
4x + 1 - x = -2(x - 3)
3x + 1 = -2x + 6
3x + 2x = 6 - 1
5x = 5
x = 1

Find the value of x in the triangle shown below
Answer:
Step-by-step explanation:
Pythagorean theorem,
Base² + altitude² = hypotenuse²
x² + 3² = 6²
x² + 9 = 36
x² = 36 - 9
x² = 27
x = √27
Answer:
D) x=sq rt 27
Step-by-step explanation:
using the Pythagorean theorem
6^2=3^2+x^2
36=9+x^2
27=x^2
x=sq rt 27

What is the slope of the line?
Answer:
1
Step-by-step explanation:
[tex]\frac{rise}{run}=slope[/tex]
[tex]\frac{1}{1} =1[/tex]
therefore the slope is 1
plz mark me brainliest. :)
Answer:
y = x + 5
1 would be the slope AKA m
Step-by-step explanation:
y = mx + b
mx is change of y to the change in x.
m is the slope
As you can see in the problem above, everytime y moves up 1, x moves to the right 1.
b is the y intercept - where is y when x is at 0?
This will help you find the slope of future problems hopefully. :)
Help please I don’t know what to do!!!!!
Answer:
[tex]y = 2(2) {}^{x} [/tex]
Step-by-step explanation:
It ask us to create a exponential function. A exponential function is represented by a equation like this
[tex]y = ab {}^{x} [/tex]
where a is the vertical stretch, b is the constant rate of growth, and x is the nth exponet.
Using the point 0,2
we can plug that in to find a part of the equation above.
let x=0 and y=2
[tex]2 = ab {}^{0} [/tex]
[tex]b {}^{0} = 1[/tex]
[tex]2 = a \times 1[/tex]
[tex]a = 2[/tex]
Let update the equation now since a equal 2
[tex]y = 2b {}^{x} [/tex]
Now let use point 2,8 to find the b value
let x=2 and y=8
[tex]8 = 2b {}^{2} [/tex]
Divide both sides by 2
[tex]4 = {b}^{2} [/tex]
take the sqr root of 4
[tex]b = 2[/tex]
Let update the equation
[tex]y = 2(2) {}^{x} [/tex]
how to solve for x???
Answer:
B) [tex]10\sqrt{3}[/tex]
Step-by-step explanation:
So basically it's divided into 3 similar triangles and using ratios we can try to find x
long side/short side = long side/short side
(20)/(x) = (x)/(15)
[tex]x^{2}[/tex] = 300
x = [tex]10\sqrt{3}[/tex]
I really hope I didn't make that too complicated-

Step-by-step explanation:
Which correlation coefficient represents the strongest downward trend in a data set? -0.83 -0.23 0.12 0.92
Answer: -0.83
Step-by-step explanation:
A correlation coefficient(r) is used to determine the strength and direction of the relationship between two variables.
-1 ≤ r ≤1
For downward trend r is negative.
For strong correlation r should be closer to 1 or -1.
From the given correlation coefficients -0.83 is both negative and closer to -1.
Hence, a correlation coefficient represents the strongest downward trend in a data set = -0.83

The measure of two side of a triangle are given if p is the perimeter and p=18x+9y find the measure of the third side
Answer:
10x + 6y
Step-by-step explanation:
Let t = length of the third side
3x + 4y + 5x - y + t = 18x + 9y
8x + 3y + t = 18x + 9y
t = 10x + 6y
