The function f is given by f(x) = 2*, while the function g is given by g(x) = 4.2%.
Kiran says that the graph of g is a vertical scaling of the graph off. Mai says that the
graph of g is a horizontal shift of the graph off. Do you agree with either of them?
Explain your reasoning.
DO
I agree with Kiran that the graph of g(x) = [tex]4* 2^{x}[/tex] is a vertical scaling of the graph of f(x) = [tex]2^{x}[/tex],
Define the term scaling of the graph?Scaling of the graph refers to the process of stretching or shrinking a graph of a function either vertically or horizontally, while maintaining the shape of the graph.
If the function f is given by f(x) = [tex]2^{x}[/tex],
the function of g is given by g(x) = [tex]4* 2^{x}[/tex]
I agree with Kiran that the graph of g(x) = [tex]4* 2^{x}[/tex] is a vertical scaling of the graph of f(x) = [tex]2^{x}[/tex],
To see this, note that both functions have a base of 2 raised to the power of x. However, the function g has an additional factor of 4 multiplying [tex]2^{x}[/tex]. This means that g is 4 times larger than f for any given value of x.
On the other hand, I disagree with Mai that the graph of g is a horizontal shift of the graph of f. A horizontal shift occurs when a function is moved left or right along the x-axis. However, both f and g have the same base, so the shape of their graphs is the same. The only difference is the vertical scaling due to the additional factor of 4 in g.

Gene has a gasoline budget of $300 per month. He uses an average of $7 of gasoline each day he drives. Which of the following equations represents how much money is left in his gasoline budget after x days of driving? A. y = 300 + 7x B. y = 7x - 300 C. y = 300x - 7 D. y = 300 - 7x
Answer:
y=300-7x
Step-by-step explanation:
since monthly budget for gasoline=$300
Per day, he uses an average of $7 of gasoline
after x days he will use $7x of gasoline.
remaining amount after x days of driving= 300-7x
the equation will be y= 300-7x

A rectangular prism has a height of 4.5 cm, length of 7.2 cm and a width of 9 cm. Joe is going to cover the sides only. How much paper will he need?
Answer:
210.6cm^2
Step-by-step explanation:
1) In the diagram below the shape of the rectangular prism is shown:
where L=7.2, W= 9 and H=4.5
In order to cover only the sides, the area of the front and back faces and the side faces should be added, the top and bottom faces should not be
so the area of front and back faces= 2 (length *width) (multiply by 2 to account for both the front and back face, instead of just one face)
=2(7.2)(9)= 129.6 cm^2
area of side faces: 2(W)(H)=2*9*4.5=81cm^2
129.6cm^2+81cm^2=210.6 cm^2
When Fritz drives to work his trip takes 35 minutes, but when he takes the train it takes 15 minutes. Find the distance Fritz travels to work if the train travels an average of 80 miles per hour faster than his driving. Assume that the train travels the same distance as the car.
Answer:
35 miles
Step-by-step explanation:
Let's say Fritz travels at x miles per hour via train and y miles per hour via car.
(speed of car) + 80 miles per hour = speed of train
y + 80 = x
Speed * time = distance
Speed of train * time of train = distance = speed of car * time of car
x * 15 minutes = y * 35 minutes
convert minutes to hours since miles per hour is in terms of hours
60 minutes = 1 hour
15 minutes = ? hours
multiply 15 minutes by 1 hour/60 minutes. since 60 minutes = 1 hour, we can divide both sides by 60 minutes to get 1 hour/60 minutes = 1. we can always multiply by 1, so we do that here. note that the minutes are in the denominator so the 15 minutes cross out with the 60 minutes, leaving us with only hours as our unit.
15 minutes = 15 minutes * 1 = 15 minutes * 1 hour/60 minutes = 15/60 hours = 3/12 hours
similarly, 35 minutes * 1 hour/60 minutes = 35/60 hours = 7/12 hours
x * 15 minutes = y * 35 minutes
x * 3/12 hours = y * 7/12 hours
plug y+80 in for x
(y+80) * 3/12 hours = y * 7/12 hours
(3/12) * y + 20 = (7/12) * y
subtract (3/12) * y from both sides to isolate the variable (y) and its coefficient
20 = (4/12) * y
multiply both sides by 12/4 (the inverse of the coefficient) to get rid of the coefficient
20*12/4 = y = 60
y = 60 miles per hour
x = y + 80 = 140 miles per hour
distance = x * 3/12 hours = 140 miles/hour * 3/12 hours= 35 miles

Ben is climbing a tree with a lot of branches. His height off the ground at time $t$ is $2t^2-5t+29$ feet. To the nearest foot, what will his minimum height be?
Using the vertex of the quadratic equation, it is found that his minimum height will be of 25.875 feet.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The vertex is given by:
[tex](x_v, y_v)[/tex]
In which:
[tex]x_v = -\frac{b}{2a}[/tex]
[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]
Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.In this problem, the equation is:
h(t) = 2t² - 5t + 29.
Hence the coefficients are a = 2 > 0, b = -5, c = 29, and the minimum height in feet is given by:
[tex]y_v = -\frac{(-5)^2 - 4(2)(29)}{4(2)} = 25.875[/tex]

Ben minimum height above the ground when climbing the tree would be 25.875 feet
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Given that:
h(t) = 2t² - 5t + 29
The minimum height is at h'(t) = 0, hence:
h'(t) = 4t - 5
4t - 5 = 0
t = 5/4
h(5/4) = 2(5/4)² - 5(5/4) + 29 = 25.875 feet
Ben minimum height above the ground when climbing the tree would be 25.875 feet

16.7 cm
5.1 cm
11.4 cm
4.1 cm
Applying the sine ratio and the Pythagorean theorem, the adjecent length to angle β is: A. 16.7 cm.
What is the Sine Ratio?The sine ratio is given as, sin ∅ = opposite/hypotenuse.
Given the following in a right triangle:
∅ = β sin(β) = 0.292Hypotenuse = 17.5 cmFind the opposite side by applying the sine ratio:
0.292 = opp/17.5
Opposite = (0.292)(17.5)
Opposite = 5.11
Using the Pythagorean theorem, we have:
Adjacent length = √(17.5² - 5.11²)
Adjacent length = 16.7 cm.
Thus, applying the sine ratio and the Pythagorean theorem, the adjecent length to angle β is: A. 16.7 cm.

So basically if you buy a pizza and you were originally going to cut it in 3 pieces, but then one of your other friend wants a piece, so now you will have to cut it into 4 pieces which will give you a smaller piece and the same way cutting a pizza into 7 pieces will make it way smaller
