Answer:
D. The graph of y = |x| – 4 is the same as y = |x|.
Step-by-step explanation:
The graph y=|x|-4 is obtained from the graph y=|x| dy moving down 4 units the graph y=|x| along the y-axis (see, if x=0, then for y=|x|, y=0 and for y=|x|-4, y=-4).
These two graphs have the same form.

Answer:
y= -x +9
Step-by-step explanation:
The general equation of a line in slope intercept form is y=mx+b, where m is the slope and b is the y-intercept
For the given graph
Thake ANY 2 points on the line, for example (0,9) and (9,0) and calculate the slope
m= difference in y coordinates/ difference in x coordinates
=(9-0)/ (0-9) = 9/-9 = -1
b =9 because the given line is intersecting the y-axis at point (0,9)
The euation of the red line is y= -x +9
Kevin wants to make the best choice for his retirement plan. He can withdraw money weekly, monthly, or
quarterly. He needs to compare all three options and see if there is a difference in these three cases. He has
$250,000 saved for retirement in an account earning 3.5% interest. He plans to make regular withdrawals
for 25 years.
Compare these three options to see which one is more beneficial for Kevin. When you make comparison,
you should at least calculate
1. the amount he can withdraw each time period
2. the amount in total he can withdraw in 25 years
What observation can you make about the withdraw frequency when the interest rate stays the same?

My friend has $280 to spend on a fence for her rectangular garden. She wants to use cedar fencing which costs $13/foot on one side, and cheaper metal fencing which costs $7/foot for the other three sides.
What are the dimensions of the garden with the largest area she can enclose?
length for cedar side = ___foot
width for other side = ___foot
What is the largest area that can be enclosed?
area = ____foot-squared
If necessary, round your answers accurate to two decimal places.
What are the dimensions of the garden with the largest area she can enclose?
The dimensions of the garden with the largest area she can enclose are length for cedar side = 7 foot and width for other side = 10 foot
Let L = length of the fence and W = width of the fence.
Also, let L be the length of cedar fencing.
Since we require one side of cedar fencing and the other 3 sides of cheaper metal fencing, and the cedar fencing costs $13/foot and the cheaper material costs $7/foot, the total cost of fencing is C = 13L + 7L + 2W × 7
= 13L + 7L + 14W
= 20L + 14W.
Since the total amount my friend wants to spend on fencing is $280, C = 280.
So, 20L + 14W = 280
10L + 7W = 140 (1)
Also, the area of the rectangular area is A = LW
From (1), L = (140 - 7W)/10
Substituting L into A, we have
A = LW
A = (140 - 7W)W/10
A = 14W - 0.7W²
To find the value of W that makes A maximum, we differentiate A with respect to W.
So, dA/dW = d(14W - 0.7W²)/dt
dA/dW = 14 - 1.4W
Equating it to zero, we have
14 - 1.4W = 0
14 = 1.4W
W = 14/1.4
W = 10 feet
To determine if this value maximizes A, we differentiate dA/dW with respect to W.
So, d²A/dW² = d(14 - 1.4W)/dW = -1.4
Since d²A/dW² = -1.4 < 0, W = 10 feet is a maximum point.
Since L = (140 - 7W)/10,
substituting W = 10 into the equation, we have
L = (140 - 7W)/10
L = (140 - 7 × 10)/10
L = (140 - 70)/10
L = 70/10
L = 7 feet
So, the dimensions of the garden with the largest area she can enclose are length for cedar side = 7 foot and width for other side = 10 foot
What is the largest area that can be enclosed?
The largest area that can be enclosed is area = 70 foot-squared
Since the area A = LW
Substituting the values of L and W into the e quation, we have
A = LW
A = 7 × 10
A = 70 ft²
So, the largest area that can be enclosed is area = 70 foot-squared

Two sides of a parallelogram are 6.7 feet and 5.6 feet. The measure of the angle
between these sides is 152°. Find the area of the parallelogram to the nearest 10th of
a square foot.
Step-by-step explanation:
Area parallelogram = a×b×sin (x)
a, b = 6.7 ft and 5.6 ft
x = 152 degrees
so, we have
6.7×5.6×sin(152) = 37.52×sin(152) = 17.61457304... ft²
the rounded area is 17.6 ft².

Evaluate the expression when x = 1/4 and y = 1/2
2 (1/16 + x2) + 5y
Answer:
2 3/4
Step-by-step explanation:
x = 1/4
y = 1/2
so we have to plug in these numbers wherever we see x and y
2 (1/16 + (1/4)^2) + 5(1/2)
using pemdas we solve what's in the parenthesis first
(1/16 + (1/4)^2) = (1/8)
next is multiplication so
2 (1/8) = 1/4 and 5(1/2) = 5/2
lastly we add so
1/4 + 5/2 = 11/4 or 2 3/4

Identify the pairs of supplementary angles in the figure
Answer:
1st option is correct exactly
..............
Consider the function f ( x ) = cos ( 0.65 x ) f(x)=cos(0.65x). How much does x x have to vary for the argument of f f to vary by 2 π 2π?
We want to see how much must vary x so the argument of f(x) varies by 2 pi. We will see that x must vary (2π)/0.65.
So let's take the variation from 0 to 2π.
The argument is zero when x = 0
Argument = 0.65*x
if x = 0
Argument = 0.65*0 = 0
Now let's see which must be the value of x such that the argument is equal to 2π, so we must solve:
2π = 0.65*x
(2π)/0.65 = x
So we can see that x must vary from 0 to (2π)/0.65, or just a variation of (2π)/0.65.

Candace is designing a rectangular tile that has a width of 3/5 meter and an area of 9/10 meter what is the length of the tile Candace is designing
The length of the tile Candace is designing is 3 /2 meters.
The rectangular tiles he is designing has the following dimension:
width = 3/5 meters
area = 9/10 meters
The length of the tiles Candace is designing can be calculated below:
area of a rectangle = lw
where
l = length
w = width
Therefore,
9/10 = 3/5 l
cross multiply
9 × 5 = 3 × 10l
45 = 30l
divide both sides by 30
45 / 30 = l
l = 9 / 6 = 3 / 2 meters
length = 3 / 2 meters
