Answer:
the area of the circle is 4π
Step-by-step explanation:
The computation of the area of the circle is shown below:
As we know that
The area of the circle = πr^2
where
diameter = 4
So radius = diameter ÷ 2
= 4 ÷ 2
= 2
Now the area of the circle is
= π × 2^2
= 4π
hence, the area of the circle is 4π
What is the solution to the equation?
√2x+10−6=2
*Picture of the Problem Below*
Answer:
x = 27
Step-by-step explanation:
Given
[tex]\sqrt{2x+10}[/tex] - 6 = 2 ( add 6 to both sides )
[tex]\sqrt{2x+10}[/tex] = 8 ( square both sides )
2x + 10 = 8² = 64 ( subtract 10 from both sides )
2x = 54 ( divide both sides by 2 )
x = 27

The roots of the equation x^2+bx+x=0 are -4 and 2.
Find B and C
Answer:
b = 2, c = - 8
Step-by-step explanation:
Given x = a is a root then (x - a) is a factor
Here the roots are x = - 4 and x = 2 , then the corresponding factors are
(x + 4) and (x - 2)
The equation is then the product of the factors , that is
(x + 4)(x - 2) = 0 ← expand factors using FOIL
x² + 2x - 8 = 0
with b = 2 and c = - 8
One equation in a system of equations is y=2x+4. Which of the following would be the second equation so that the system has (1,6) as its only solution
1. y=-2(x+2)
2. y=2x+8
3. y=5x+1
4. y=4x-7
Answer:
1. y = 2(x + 2)
Step-by-step explanation:
if we substitute the values,
we get 6 = 2*1 + 4
6 = 6
therefore, it is correct.
The system of equations has no solution. hence option d is correct.
What is Equation?Equation is described as the state of being equal, and it is commonly represented as a math expression with equal values on both sides, or it refers to a problem involving numerous variables.
here, we have,
to find solution to the system:
The given equation is
y=2x+8 ..(1)
3(-2x + y) = 12 ...(2)
Substitute the y value in equation 2 from equation (1)
3(-2x + 2x+8) = 12
3(8)=12
24≠12
Hence the system of equations has no solution.

a baseball team played 32 games and lost 8 . Katy was the catcher in 5/8 of the winning games and 1/4 of the losing games. what fraction of the games did the team win? and how many games did Katy play catcher
Answer:
17
Step-by-step explanation:
what you have to is simple, first do 32-8 which get you 24, thats how many they won. Then do 8x1/4 to get 2, she played 2 games as catcher and lost, then do the same thing with the winning games. 24x5/8 should get you 15. she played 15 games as catcher and won. then do 15+2 to get 17.
hope that helps!
Answer:
1/4 - won
7/8 - katy played catcher
hope this helps you :)

method was used?
O cluster sampling
simple random sampling
O stratified random sampling
O systematic random sampling
Answer:

f(1) = 0.5(x + 6)(x - 2)
7(4) = 0.5(4 - 6)(x + 2)
2(x + 6) (3 - 2)
Answer: first graph is F(x) = 0.5(x-6) (x+2)
Second graph f(x) = (x - 3) ( x + 1 )
Third graph f(x) = -2(x - 1) (x + 3 )
Step-by-step explanation:
Type functions into Desmos graphing calculator and it will plot the points for you.

The required quadratic function shown in the graph is
f(x)=0.5(x+2)(x-6).
Let us suppose the quadratic function
[tex]f(x)=a(x-\alpha )(x-\beta )[/tex]......(1)
where α and β are roots of the quadratic equation f(x)=0
What is a quadratic equation?Any equation of the form [tex]ax^{2} +bx+c=0[/tex] is called a quadratic equation where a≠0
From the shown graph we can see the roots of f(x)=0 as:
[tex]\alpha =-2[/tex]
[tex]\beta =6[/tex]
So, (1) becomes [tex]f(x)=a(x+2 )(x-6 )[/tex].....(2)
Since the graph is intersecting the y-axis at (0, -6)
So, (0, -6) will satisfy the (2)
So put x=0 and f(x)= -6 in (2)
[tex]-6=a(0-2)(0-6)[/tex]
[tex]a=\frac{-1}{2}=0.5[/tex]
So, [tex]f(x)=0.5(x+2 )(x-6 )[/tex]
Thus, the required quadratic function shown in the graph is
f(x)=0.5(x+2)(x-6).

Ancient slingshots were made form straps of leather that cradled a rock until it was released. One would spin the slingshot
in a circle, and the initial path of the released rock would be a straight line tangent to the circle at the point of release.
The rock will travel the greatest distance if it is release when the angle between the normal to the path and the horizontal
is -450. The center of the circular path is the origin and the radius of the circle measure 1.25 feet.
Write and equation of the initial path of the rock in standard form.
Answer:
Step-by-step explanation:∠ MON= -45°→→ angle lies in fourth quadrant.
Where, MN represents the path of rock, which is a straight line.
Taking the Horizontal and vertical component of OM,to get the coordinate of point M
The coordinate of point M will be [1.25 cos (-45°), 1.25 sin(-45°)]=
Taking O as center and Coordinates of O as (0,0) and Coordinates of M as () we get the equation of line OM as
y= tan (315°)× x
As general form of equation of line passing through the origin will be,
y= m x, where m is angle made by line with positive direction of x axis.
m= (360-45)°= 315°
→→y=-x
→→ y + x=0
equation of line perpendicular to OM will be
→→ x - y + k=0
Since it passes through .

So, equation of initial path of stone will be:

A North Dakota license plate has six characters: 3 digits followed by 3 letters (e.g. 123AAA). Any number from 0 to 9 can be used as a digit. Any of the 26 letters from A to Z can be used as a letter.
How many different North Dakota license plates can be issued?
Answer:
17,576,000
Step-by-step explanation:
Since, there is 3 digits, 0-9, you would have 10 numbers total to choose from. As well as the 26 letters. Since you need three of each, you multiply.
10*10*10*26*26*26
