If the garden is 5 feet long, how many feet will Cho need to cover with garden stones?
Cho will need to cover _______ feet with garden stones.
Answer:
38 feet
Step-by-step explanation:
P(x) = ℓ(x) + ℓ(x) + w(x) + w(x)
= x + x + (4x - 1) + (4x - 1)
= (x + x + 4x + 4x) + (-1 -1)
= 10x - 2
P(4) = 10(4) -2 = 38
The perimeter is 38 feet when the length is 4 feet long, so Cho will need to
cover 38 feet with garden stones.

Answer:
A. Reflection over the x-axis.
Step-by-step explanation:
Now, we present how to transform [tex]f(x) = x[/tex] into [tex]g(x) = -5\cdot (x-3)-8[/tex] below:
1) [tex]f(x) = x[/tex] Given.
2) [tex]f(x-3) = x - 3[/tex] Horizontal shift to the right.
3) [tex]-5\cdot [f(x-3)] = -5\cdot (x-3)[/tex] Vertical scale factor.
4) [tex]-5\cdot f(x-3)-8 = -5\cdot (x-3)-8[/tex] Vertical shift downwards.
5) [tex]g(x) = -5\cdot (x-3)-8[/tex] Definition/Result
In consequence, the only transformation which was not done to the linear parent function was a reflection over the x-axis. The correct answer is A.

They have built paved roads throughout the country, leveling ridges and filling up hollows, so as to make possible the movements of heavily loaded wagons. . . . And such is the quantity of water brought in by the aqueducts, that veritable rivers flow through the city and its sewers: almost every house has cisterns, waterpipes, and copious fountains.”

Point Q is the midpoint of AB. Q has coordinates of (-2, 4) and A has coordinates of (4,6). What are the coordinates of point B?
Step-by-step explanation:
Let (x, y) be the coordinates of point B.
(4, 6) => (-2, 4) => (x, y)
We have 2(-2) = 4 + x and 2(4) = 6 + y.
Solving these, we get x = -8 and y = 2.
Hence the coordinates of point B is (-8, 2).
Point Q is the midpoint of AB. Q has coordinates of (-2, 4) and A has coordinates of (4,6). Hence the coordinates of point B will be (-8, 2).
What are the coordinates of the midpoint of the line segment AB?Suppose we've two endpoints of a line segment as:
A (p,q), and B (m,n)
Then let the midpoint be M(x,y) on that line segment.
Then, its coordinates are:
[tex]x = \dfrac{p+m}{2}[/tex]
and
[tex]y = \dfrac{q+n}{2}[/tex]
Let (x, y) be the coordinates of point B.
Q has coordinates of (-2, 4).
A has coordinates of (4,6).
A (p,q) = (4, 6)
M(x,y)= (-2, 4)
B = (x, y)
We have
2(-2) = 4 + x
2(4) = 6 + y.
Solving these, we get
x = -8 and y = 2.
Hence the coordinates of point B will be (-8, 2).

You are going on a trip. To get to the beach, you have to drive 475 miles. If you can average 50 miles per hour on your drive, which equation shows how much farther you have to drive over time?
Answer:
C= -50x+475
Step-by-step explanation:
Step one:
given data
distance travelled = 475miles
velocity = 50miles per hour
let the distance you cover per hour be x
hence per hour, your distance decreases by 50x hours
Required:
The expression for the distance remaining
Step two:
let the distance remaining be C
hence the expression
C= -50x+475

Step-by-step explanation:
given data:
loan amount = $7500
duration = 6 months
interest rate = 2.5%
Solution:
[tex]A = P \frac{i(1+i)^{n} }{(1+i)^{n} -1}[/tex]
i = [tex]\frac{2.5}{100} \\= 0.025\\\frac{0.025}{6} \\= 0.004167[/tex]

The acceleration of an object due to gravity is 24 feet per second squared. What is the acceleration due to gravity in inches per second squared?
288 inches per second squared
B
2 inches per second squared
С
72 inches per second squared
D
3,456 inches per second squared
The acceleration due to gravity in inches per second squared is
288 inches / seconds²
Option A is the correct answer.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
1 feet = 12 inches
We have,
The acceleration of an object due to gravity:
= 24 feet / seconds²
Now,
1 feet = 12 inches
24 feet = 288 inches
So,
24 feet / seconds²
= 288 inches / seconds²
Thus,
The acceleration of an object due to gravity is 288 inches / seconds².
