3. Let's assume you purchase 100 shares of XYZ Company for $1 per share. After three months, the share price increases to $5. This means the value of the investment has increased from $100 to $500, for a capital gain of $____
Answer:
400
Step-by-step explanation:
The initial value of the investment is 100 *1 = $100
The final value of the investment after three months is 100 * 5 = $500
This means the value of the investment has increased from $100 to $500. The capital gain is the increase in the value of an investment;
500 - 100 = $400

Answer:
16.2
Step-by-step explanation:
A trick to remember for right triangles is SOH-CAH-TOA:
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Here, we have the side adjacent to the angle and the hypotenuse. So we should use cosine.
cos 22° = 15 / x
x = 15 / cos 22°
x ≈ 16.2

a. Use the Pythagorean Theorem to find the exact
length of ET.
b. How can you use the Distance Formula to find the
length of ET? Show that the Distance Formula gives
the same answer
Answer:
a. By Pythagorean Theorem: [tex]ET=\sqrt{113}[/tex]
b. By Distance Formula: [tex]ET=\sqrt{113}[/tex]
Step-by-step explanation:
The given rectangle has vertices R(-3,-4), E(-3, 4), C(4,4), and T(4-4).
The points have been plotted on the coordinate plane as shown in the attachment.
a. Using the Pythagoras Theorem;
[tex]ET^2=EC^2+CT^2[/tex]
We substitute the side lengths to obtain:
[tex]ET^2=7^2+8^2[/tex]
[tex]ET^2=49+64[/tex]
[tex]ET^2=113[/tex]
Take positive square root to obtain:
[tex]ET=\sqrt{113}[/tex]
b. The distance formula is given by:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The endpoints of ET are at E(-3,4) and T(4,-4).
Using the distance formula;
[tex]ET=\sqrt{(4--3)^2+(-4-4)^2}[/tex]
[tex]ET=\sqrt{(7)^2+(-8)^2}[/tex]
[tex]ET=\sqrt{49+64}[/tex]
[tex]ET=\sqrt{113}[/tex]
It will take Adam four hours to drive to Disney Park, and 2.5 times less time if driving 45 mph faster. What is the distance Adam should cover to get to the park?
Answer:
120 miles
Step-by-step explanation:
we know that
The speed is equal to the distance divided by the time
Let
s------> the speed in mph
d-----> the distance in miles
t -----> the time in hours
s=d/t
solve for the distance
d=s*t
It will take Adam four hours to drive to Disney Park
s=x mph
t=4 h
substitute
d=4x -----> equation A
It will take Adam 2.5 times less time if driving 45 mph faster
so
s=(x+45) mph
t=4/2.5=1.6 h
substitute
d=1.6(x+45) -----> equation B
equate equation A and equation B
4x=1.6(x+45)
Solve for x
4x=1.6x+72
4x-1.6x=72
2.4x=72
x=30 mph
Find the distance d
d=4x -----> d=4(30)=120 miles
Answer:
120 miles

11. The slope of a linear function h(x) is 2. Suppose the function is translated 8 units up to get d(x). How can h(x) be
translated to the left or right to represent the same function d(x)? Explain your answer.
Answer:
See below.
Step-by-step explanation:
If we translate h(x) to the left it will override line d(x) because the slope of both lines is the same. H(x) will need to move 4 units to the left to do this (because the slope = 2 = 8/4).
To represent the same function as d(x), the linear function h(x) with a slope of 2 should be translated 4 units to the left, resulting in the function h(x+4). This horizontal shift increases the value of y by 8 units, which equates to the vertical shift applied to create d(x).
To translate the linear function h(x) to result in the same function as d(x), which is h(x) translated 8 units up, we need to consider the properties of linear functions and translations. Since h(x) has a slope of 2, we can denote it as h(x) = 2x + b, where b is the y-intercept. When h(x) is translated 8 units up to become d(x), the new function is d(x) = h(x) + 8 = 2x + b + 8. To counteract this vertical shift with a horizontal translation and maintain the same function as d(x), we must shift h(x) in such a way that every x value for h(x) yields the same y-value for d(x) after the translation.
To achieve this, we would have to shift h(x) to the left by 4 units, resulting in the function h(x+4). This is because for every 1 unit increase in x, the value of h(x) increases by 2 units (the slope), so a shift of 4 units left would increase y by 8 units, which is the same effect as the vertical translation applied to obtain d(x). Thus, h(x+4) = 2(x+4) + b = 2x + 8 + b, which aligns with d(x). This explanation confirms that the properties of linear functions and translation mechanics allow us to equate d(x) with a horizontally translated version of h(x).

A van travels 320 miles on 16 gallons of gas. Find how many gallons the van needs to travel 420 miles
The van needs 21 gallons of gas. Take 16/(320/420)
The van will need 21 gallons of gas to travel 420 miles, based on its fuel efficiency of 20 miles per gallon.
The student is asking how many gallons of gas a van needs to travel 420 miles, given that it travels 320 miles on 16 gallons of gas.
First, we calculate the van's fuel efficiency which is found by diving the miles traveled by the gallons of gas used. For the van in the question:
Fuel efficiency: 320 miles / 16 gallons = 20 miles per gallon (MPG)
Next, we can use this fuel efficiency to find out how many gallons will be needed for 420 miles. We divide the total miles by the MPG:
Gallons needed: 420 miles / 20 MPG = 21 gallons
Therefore, the van will need 21 gallons of gas to travel 420 miles.
What is the slope and y-intercept of this line?
y = –3x + 9
slope: 9, y-intercept: –3
slope: 3, y-intercept: –9
slope: –3, y-intercept: 9
slope: 1, y-intercept: –3
Answer:
C
Step-by-step explanation:
y=mx+b
b= y-intercept
m=slope
m=-3
b=9
[tex]\huge\boxed{Slope=-3,\;Y\;intercept=9.}[/tex]
___________________________________________________________
[tex]\boxed{Explanation}[/tex]
y=mx+b.
m is always where the slope is located.
b is always where the y intercept is located.
Therefore, since -3 is located at m that is the slope and 9 is located at b so that is the y intercept.
x and y intercepts if y=3(x-1)^2-12
The x-intercepts are: (-1,0) and (3,0).
The y-intercept is: (0,-9).

How can you find the missing side length of a cube if you know the cube’s volume?
Answer:
See below
Step-by-step explanation:
In order to solve for the length of a cube, you must already know its width, depth, and volume. Then, arrange the problem as an equation:
Length x width x depth = volume
Next, solve the equation for the length. For example, If I have a cube with a width of 5ft, a depth of 5ft, and a volume of 50ft^3, I will solve for the length by arranging the values to fit the formula shown above:
L x 5 x 5 = 50
Then I'll multiply the values on the left:
25L = 50
And, finally, I will divide either side by 25, which leaves the answer:
L = 2ft
