Answer: r = 5
Step-by-step explanation:
Using Pythagoras we can find the length of the diameter
d^2 = (3 - -5)^2 + (-8 - -2)^2
= 8^2 + (-6)^2
= 64 + 36
= 100
This means d = 10 and r = 5
Charles uses a graphing calculator to find a quadratic regression model f for a given set of data. When he compares model f to an earlier regression model g for the same data, he determines that g more accurately models the data. Which of the following statements are true? Select all that apply.
A. Function f likely had fewer residuals near the x-axis than function g.
B. Function f likely had more residuals equal to 0 than function g.
C. Function g had more residuals near the y-axis than function f.
Answer:
C
Step-by-step explanation:
a is wrong because residuals are solved using y and not x
b is wrong because a residual closer to 0 would be more accurate, but f is less accurate than g
c is right because residuals are solved using y and a more accurate residual would be closer to the real answer's y value

Find three consecutive numbers such that the sum of twice the first, three times the second and four times the third togetherbmakes 191.
Answer:
find 3 consecutive numbers such that twice the first , 3 times the second and 4 times the third together make 191 ?
Let n-1,n and n+1 be three consecutive numbers.
Given
2(n-1)+3n+4(n+1)=191
2n-2+3n+4n+4=191
9n+2=191
9n = 189
n = 21
So, n-1=20 and n+1=22
So the answer is 20,21,22

$4000.00 investment. Over 3 years $1080.00 interest accumulated. What was the interest on the loan? The interest is shown in percent as the answer.
Answer:
9% interest rate
Step-by-step explanation:
Investment = principal = $4000
Interest amount = $1080
Period, t = 3 years
Simple interest = principal * rate * time
1080 = 4000 * rate * 3
1080 = 12000 * rate
Rate = 1080 / 12000
Rate = 0.09
The rate as a percentage = 0.09 * 100% = 9%

Step-by-step explanation:
Given
[tex]\frac{-4(-8.625+2d)}{-8} +3=10[/tex]
Lets solve for [tex]d.[/tex]
Start on the left side with the fraction.
Factor -4 out of -8.
[tex]\frac{-4(-8.625+2d)}{-4(2)} +3=10[/tex]
Cancel the common factor of -4.
[tex]\frac{-8.625+2d}{2} +3=10[/tex]
Subtract 3 from both sides.
[tex]\frac{-8.625+2d}{2} =7[/tex]
Multiply both sides by 2.
[tex]\frac{-8.625+2d}{2} *2=14[/tex]
Cancel the common factor of 2.
[tex]-8.625+2d=14[/tex]
[tex]2d-8.625=14[/tex]
Add 8.625 to both sides.
[tex]2d=22.625[/tex]
Divide both sides by 2.
[tex]d=11.3125[/tex]

What are the 3 different polynomial equation?
The 3 different polynomial equations are linear polynomial equations, quadratic polynomial equations, and cubic polynomial equations.
A polynomial equation is one where a polynomial is set equal to zero. i.e., it is an equation created with variables, non-negative integer exponents, and coefficients together with operations and an equal sign.
A polynomial equation is always like "polynomial = 0". Algebraically, it is of the form p(x) = aₙ xⁿ + aₙ₋₁ xⁿ⁻¹ + ... + a₁ x¹ + a₀x⁰ = 0, where
aₙ, aₙ₋₁, ...., a₁, a₀ are coefficients and all these numbers are real numbers.
'x' is the variable.
p(x) means "polynomial in terms of variable x"
'n' is a non-negative integer, it is the degree of p(x).

Answer:
option C I think
Step-by-step explanation:
I remember learning about this last year
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{3}[/tex] x - 2 ← is in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3 , then
y = - 3x + c ← is the partial equation
To find c substitute (4, - 7) into the partial equation
- 7 = - 12 + c ⇒ c = - 7 + 12 = 5
y = - 3x + 5 → D
Denise's cell phone plan is $29.95 per month plus $0.10 per minute of call time. Denise's
cell phone bill is $99.95. For how many minutes was she billed?
Answer:
700 minutes
Step-by-step explanation:
Let y represent the cost and x represent the number of minutes of call time
We have the equation
99.95 = 0.10x + 29.95
Now let's solve
99.95 = 0.10x + 29.95
70 = 0.10x
x = 700 minutes
So, she was billed for 700 minutes

Select the correct answer.A wooden board that is 108 inches long is cut into two equal parts. What is the length of each part in feet
4.5 is the length of each part in feet. This can be solved by using the concept of feet.
What is feet?foot, plural feet, any of a wide range of ancient, medieval, and modern linear measurements (often 25 to 34 cm) based on the length of the human foot and used only in English-speaking nations, where it typically consists of 12 inches or one-third yard.
The foot measured [tex]11^{\frac{1}{42}[/tex] inches in antiquity. The typical man's foot measures 12 inches in length nowadays.
Given that:
The length of the wooden board is given as = 108 inches.
As it is cut in 2 equal parts, it becomes: 108/2 = 54 inches in each
We have to calculate the length of each part in feet, so divide 54 by 12.
As we know,
12 inches = 1 feet
Thus, 54 inches = 54/12 feet = 4.5 feet
So, the length of each part is 4.5 feet.

Need help with this, finding the length of the third side
Answer:
its sqrt (50)
Step-by-step explanation:
The triangle has a right angle, therefore we can use the Pythagorean theorem to find the hypotenuse. According to the theorem the sum of the squares of both other sides is equal to the square of the hypotenuse.
We have 5^2+5^2=c^2
=> 25+25=c^2
=> 50=c^2
Therefore c or the missing side is equal to sqrt(50)
