Answer:
A. x^3 − 9x^2 + 14^x + 24
Step-by-step explanation:
(x − 4)(x^2 − 5x − 6) = x(x^2 − 5x − 6) -4(x^2 − 5x − 6)
= x^3 -5x^2 -6x -4x^2 +20x +24
= x^3 +x^2(-5-4) +x(-6+20) +24
= x^3 − 9x^2 + 14x + 24 . . . . matches the first choice
Answer:

Lin runs 5 laps around a track in 6 minutes. How many minutes per lap is that? ___minutes How many laps per minute is that? ___ laps If Lin runs 21 laps at the same rate, how long does it take her? ___minutes
Answer:
a. 1.2 minutes
b. 0.83 laps
c. 25.2 minutes
Step-by-step explanation:
Lin runs 5 laps around a track in 6 minutes.
a. How many minutes per lap is that?
5 laps = 6 minutes
1 laps = x minutes
Cross Multiply
x minute × 5 laps = 6 minutes × 1 laps
x minute = 6 minutes × 1 laps/5 laps
x laps = 1.2 minutes
Hence, it is 1.2 minutes per lap
b. How many laps per minute is that?
6 minutes = 5 laps
1 minute = x laps
Cross Multiply
6 minutes × x laps = 1 minute × 5 laps
x laps = 1 minute × 5 laps/6 minutes
x laps = 0.8333333333 laps
Hence, it is 0.83 laps per minute.
c. If Lin runs 21 laps at the same rate,
5 laps = 6 minutes
21 laps = x minutes
Cross Multiply
x minute × 5 laps = 6 minutes × 21 laps
x minute = 6 minutes × 21 laps/5 laps
x laps = 25.2 minutes
Hence, it takes her 25.2 minutes

The least-squares regression equation
y = 120 + 40x can be used to predict the cost of renting a backhoe for x hours. Suppose it costs $325 to rent a backhoe for 5 hours.
Calculate the residual for renting the backhoe for 5 hours, to the nearest hour.
The residual is _____
Answer:
5
Step-by-step explanation:
just did on edge
The residuals is $5
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given, The least-squares regression equation
y = 120 + 40x
This equation can be used to predict the cost of renting a backhoe for x hours
If it costs $325 to rent a backhoe for 5 hours.
We need to Calculate the residual for renting the backhoe for 5 hours,
Plug 5 in place of x in equation
y=120+40(5)
y=120+200
y=320
Since the The observed value is $325.
To find residual for renting the backhoe for 5 hours
We have to separate 320 from 325
325-320=5
Hence the residual is 5.

Is y=2x-4 a linear equation?
Answer:
Yes
Step-by-step explanation:
When graphed, the equation will produce a straight line, making it linear.
The vertices of a triangle are A(-2, 1), B(2, 2) and C(6, - 2).
Find the equation of the altitude of AD drawn from A to BC.
Answer:
The equation of altitude AD drawn from A to BC will be:
[tex]y=x+3[/tex]
Step-by-step explanation:
Let m₁ and m₂ be the slope of line AD and BC respectively.
Now, AD⊥BC
∴ m₁ × m₂ = -1
be the slope of line AD and BC respectively.
⇒ m₁ = -1/m₂ → (A)
Finding the slope of BC using points
B(2, 2)
C(6, - 2)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(2,\:2\right),\:\left(x_2,\:y_2\right)=\left(6,\:-2\right)[/tex]
[tex]m_{2} =\frac{-2-2}{6-2}[/tex]
[tex]m_{2} =-1[/tex]
On substituting the value of m₂ in equation (A)
m₁ = -1/m₂
= -1/(-1)
= 1
We know that the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
∴ Equation of altitude AD passing through A(-2, 1) with slope 1 will be
[tex]y-1=1\cdot \left(x-\left(-2\right)\right)[/tex]
[tex]y-1=x+2[/tex]
[tex]y=x+3[/tex]
Therefore, the equation of altitude AD drawn from A to BC will be:
[tex]y=x+3[/tex]

Find the perimeter of a rectangular garden that measures 4 yards by
12 yard.
Answer:
it is 48 yards
Step-by-step explanation:
what You would do is this 12x4, which would equal 48
Answer:
32 yards
Step-by-step explanation:
First we need to know what perimeter is. It's similar but not the same as area. The perimeter is the length around the entire area, or in this case, a garden. We know 2 side lengths of the garden and because it is a rectangle we just have to add another width and length the same as these and add them all together.
4 + 4 + 12 + 12
8 + 24
32
So, the perimeter of the rectangular garden is 32 yards.

Show or explain your work through either decimal or fractional calculation.
Answer:
28.75inStep-by-step explanation:
We are expected to convert all units to inches in this problem
Step one:
given data
blue ribbon=6.25 inches
orange ribbon=0.375 foot
green ribbon=0.5 yard
Step one:
convert orange ribbon=0.375 foot to inches
1 ft = 12 in
0.375ft=xin
cross multiply
x=12*0.375
x=4.5in
orange ribbon= 4.5in
convert green ribbon yd to inches
1 yd = 36 in
0.5 yd=xin
cross multiply
x=36*0.5
x=18in
green ribbon= 36in
total lenght in inches =6.25+4.5+18
=28.75in
