The give quadratic function is dilated by the given coefficient, and shifted

horizontally to the left.

(a) The transformation of the common function f(x) are;

  • f(t) is made more wider than f(x)
  • f(t) is shifted more to the left than the common function f(x).

Please find attached the required graph created with MS Excel

(b) Where t = 0, represent the year 2,000 we have;

  • <u>f(t) = 0.0037·(t + 24.979)²</u>

(c) The mortgage debt in the year 2014 is M ≈ <u>$5.622 trillion</u>

Reasons:

The given function is f(t) = 0.0037·(t + 14.979)²

Year 1990 is t = 0

(a) The given common function is; f(x) = x²

The transformation of the quadratic function are;

The coefficient 0.0037 widens the common function such that f(t) is wider

than f(x).

The constant, 14.979 added to the variable, <em>t</em>, shifts the graph of the

common function horizontally to the left.

Therefore;

  • <u>f(t) is wider and shifted to the left more than the common function f(x)</u>

Please find attached the required graph over the interval 0 ≤ t ≤ 19 created with MS Excel.

(b) The amount of mortgage debt in 2,000 is given as follows;

With t' = 0 represent the year 2,000, we have;

At year 1990, t' = -10

Which gives, t' = t + 10

From which we have;

f(t) = 0.0037·(t + 14.979)² = 0.0037·(t' + 10 + 14.979)²  = 0.0037·(t' + 24.979)²

Therefore;

The function with t = 0 representing the year 2,000 is presented as follows;

<u>f(t) = 0.0037·(t + 24.979)²</u>

(c) In the year 2014, we have;

t = 2014 - 2000 = 14

Which gives;

f(14) = 0.0037·(14 + 24.979)² ≈ 5.622

The mortgage debt in the year 2014 is M ≈ <u>$5.622 trillion dollars</u>

The cost, in dollars, of a one-day car rental, is given by C (x) = 31 + 0.18x, where x is the number of miles driven. In this fu
julia-pushkina [17]

Answer:

hi

Step-by-step explanation:

the function is c(x) = 31 + 0.18*x

where $31 is a fixed cost, and $0.18 is the cost per mile drive (where the number of miles driven)

So the fixed cost, $31, is the cost per day of rent (this price does not depend on the number x), and the linear cost, $0.18, is the cost per mile driven (because this number is multiplied by x in the function), then the right answer is B: "$31 is the cost per day to rent the car and $0.18 is the cost per mile."

Find the value of x. Round to the nearest tenth of a unit. Both 9 and 10 please.
Anestetic [448]
Problem 9
By definition,
tan 22^{o} =  \frac{203}{x} \\ 0.404 =  \frac{203}{x}  \\ x =  \frac{203}{0.404}= 502.44

Answer: 502.4 m

Problem 10
From geometry, the angle opposite x is 27°.
By definition,
sin 27^{o} =  \frac{x}{580} \\ 0.454 =  \frac{x}{580} \\ x=(580)(0.454)=263.32&#10;

A regular six sided die and an eight equal segment spinner, numbered 1 to 8, are rolled/spun simultaneously. What are the odds i
kirill [66]

Answer:

1/3

Step-by-step explanation:

In statistics, the probability of both an event A and an event B happening is equal to the probability of A happening multiplied by the probability of event B happening.

Let's say spinning a prime number is event A and rolling a number ≤ 4 is event B.

There are 8 possibilities on an eight equal segment spinner, and there are 4 prime numbers between 1 and 8 (including 8), which are 2, 3, 5, and 7. This means that the probability of spinning a prime number is 4/8, or 1/2

There are 6 possibilities on a die, and there are 4 possibilities of rolling a 4 or less (1, 2, 3, 4). Therefore, the probability of rolling 4 or less on a die is 4/6, or 2/3

The probability of both of these happening can be calculated by multiplying these together, so 1/2 * 2/3 = 2/6 = 1/3
