Given the function f(x) = x2 and k = 3, which of the following represents the graph becoming more narrow? A. f(x)+kB. kf(x)
C. f(x+k)
D. f(x-k)

Answers

Answer 1

Answer: The only type of transformation that can make a graph more narrow/wide is a scaling transformation. A scaling transformation involves a multiple factor. The answer to your question is B. I hope that this is the answer that you were looking for and it has helped you.

Answer 2

Answer:

The following which represents the graph becoming more narrow is:

B. kf(x)

Step-by-step explanation:

We are given a parent function f(x) as:

$f(x)=x^2$

and k=3

Now, we know that the transformation of the type:

f(x)+k

shifts the graph of the function k units upward while there is no change in the shape of graph.

Similarly the transformation f(x+k) and f(x-k) shifts the graph of the original function k units to the left and k units to the right but odes not change the shape of the function.

Hence, the answer is:

B. kf(x)

Since, the transformation is a vertical compression and the graph becomes more narrow.

An experiment is designed to determine the launch angle that will give a projectile the greatest range (make it go the longest distance). The "launcher" is a slingshot type of apparatus that is spring-loaded and released by a trigger. For each trial, the same painted rock is retrieved and launched. Measurements are taken linearly from the launch site to the landing site. The trials were done on a windless day.Which of the following would be a good hypothesis for this experiment? If the angle of the launcher is increased, the rock will go further. Changing the angle of the launcher will vary the distance that the rock can be projected.

Marcus baked a loaf of banana bread for a party. He cut the loaf into equal size pieces. At the end of the party, there were 6 pieces left. If Marcus told you that 1 4 of the loaf was left, how can you find the number of pieces that were in the whole loaf? Complete the explanation. The denominator in 1 4 is , so I will draw circles to show the equal parts. Since pieces are 1 4 of the loaf, I will draw counters in each circle. By multiplying the number of equal parts by the number of counters in each equal part, I know that there were equal size pieces in the whole loaf.

Answer:

6*4 = 24

Hopefully that helps, and you can write fractions as x/y.

Answer:

6×3 because 6 is one third of the whole loaf and 6×3 are 18.

Answers

Answer:

Bottle B has a larger volume of lotion therefore the correct answer

Step-by-step explanation:

1×2×6=12/3=4 Bottle A

1.5×3×4=18/3=6 Bottle B

Answer:

Bottle B contains 6 in3 of lotion, and Bottle A contains 4 in3. Bottle B contains more.

When Lisa and Tom has their first child, they put $7,500 into a savings account that earns 6% compound interest. If Lisa and Tom did not add or remove anything from the savings account, how much interest will they have earned after 4 years?

Answers

Answer:

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = $7500

r = 6% = 6/100 = 0.06

Assuming the interest was compounded annually, then

n = 1 because it was compounded once in a year.

t = 4 years

Therefore,

A = 7500(1 + 0.06/1)^1 × 4

A = 7500(1.06)^4

A = $9468.6

The interest that they would have earned after 4 years is

9468.6 - 7500 = $1968.6

If two lines are perpendicular, then they form:

If two lines are perpendicular, they form a 90° angle, or a right angle. By definition, two perpendicular lines intersect at a right angle. For instance, a vertical line and a horizontal line will cross at a 90° angle.

Flve tickets to a carnlval cost $45. How much would seven
tickets cost?

Answers

Answer:

$63

Step-by-step explanation:

In order to solve this problem, we need to find the unit price, which is the price per 1 ticket in this case. To find this, we need to divide $45 by 5 because each ticket is the same amount: $45 / 5 = $9. So each ticket is $9.

Now, we need to find how much 7 tickets would cost. To do this, multiply the $9 / ticket by 7 tickets: $9 * 7 = $63.

This, 7 tickets would cost $63.

Hope this helps! God Bless u!!!

Answer:

Step-by-step explanation:

because each ticket is $9 each
