Is the function y=|x-5|a one to one function? Justify your answer

Answers

Answer 1

Answer:

no

Step-by-step explanation:

if a=0 it's y=0, it's not one to one

if ais not 0, it's a even function and it's not 1 to 1, for example a=1, x=8 and x=2 have same f(x)

What is the domain of the equation that is graphed?

Answers

Step-by-step explanation:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis. Keep in mind that if the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values. See Figure 6.

Figure 6

We can observe that the graph extends horizontally from

\displaystyle -5

−5

to the right without bound, so the domain is [−5,∞). The vertical extent of the graph is all range values 5 and below, so the range is (−∞,5]. Note that the domain and range are always written from smaller to larger values, or from left to right for domain, and from the bottom of the graph to the top of the graph for range

Garrett's coin bank contains 500 nickels,
dimes, and quarters. He has the same
number of nickels as dimes, and the total
value of the coins is $72.50. How many
quarters does he have?

Answers

Step-by-step explanation:

d = number of dimes

n = number of nickels

q = number of quarters

d + n + q = 500

d×$0.10 + n×$0.05 + q×$0.25 = $72.50

n = d

we are focusing now on one variable (let's try d), and we are transforming the other equations to express the other variable by this one variable.

since n = d we have already

d + d + q = 500

2d + q = 500

q = 500 - 2d

with that we go into the main equation

d×0.10 + d×0.05 + (500 - 2d)×0.25 = 72.50

d×0.15 + (500 - 2d)×0.25 = 72.50

d×0.15 + 500×0.25 - 2d×0.25 = 72.50

d×0.15 + 125 - d×0.50 = 72.50

-d×0.35 = -52.50

d = 52.50/0.35 = 150

n = d = 150

q = 500 - 2d = 500 - 2×150 = 500 - 300 = 200

so, he has 200 quarters.

You have just purchased a car and, to fund the purchase, you borrowed $32,000. If your monthly payments are $615.13 for the next 5 years, what is the APR of the loan?

Answers

9514 1404 393

Answer:

  5.76%

Step-by-step explanation:

There is no formula for APR. It must be found using an iterative calculation, as from a spreadsheet or financial calculator.

__

The value can also be found graphically from the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

where A is the monthly payment, P is the principal amount of the loan, r is the annual rate, and t is the number of years.

This can be put into a form that can be solved easily by a graphing calculator. We want it to find the x-intercept of f(x) = 0, so we define ...

  f(x) = A(P, x/100, t) -615.13

where A(P, r, t) is defined above, and we let r = x/100 so x is the APR. The graph shows us the APR is 5.763%.

Using the probability concept, it is found that there is a 0.6087 = 60.87% probability of a puppy having no spots.

A probability is the number of desired outcomes divided by the number of total outcomes, that is:

[tex]p = \frac{D}{T}[/tex]

In this problem:

There are 6 + 8 + 4 + 5 = 23 puppies, thus [tex]T = 23[/tex].6 +8 = 14 have no spots, thus [tex]D = 14[/tex]

Then, the probability is:

[tex]p = \frac{D}{T} = \frac{14}{23} = 0.6087[/tex]

0.6087 = 60.87% probability of a puppy having no spots.

Which pair of numbers are not opposites?
|7| and -7
17 and – 17
17 and | -17|
71 and - 71

Answers

Answer:

The answer is C, 17 and | -17|

Step-by-step explanation:

We can solve this using the process of elimination.

Looking at the first one, we know that those | | around the 7 mean to find the absolute value. The absolute value is the number of units the number is from zero, and it is always positive. This means that it is saying 7 and -7. Those are opposites, so we know that this isn't right.

17 and -17 are opposites, since the opposite of a positive is a negative.

The last one is the same. 71 and -71 are opposites. That leaves us with C.

Remember that those | | mean to find the absolute value of. -17 is 17 unites from zero. So is 17 the oppostie of 17? No, so these are not opposites, and therefore are our answer.

The answer is 17 and |-17| because they both equal positive 17.

Given the recursive formula shown, what are the first 4 terms of the sequence?

Answers

Applying the recursive formula f(n) = f(n-1) + 4 with the initial condition f(1) = 3, we obtain the sequence 3, 7, 11, 15, which corresponds to option D) in the given choices. Optiopn D

To find the values of the sequence defined by the recursive formula f(n) = f(n-1) + 4, with the initial condition f(1) = 3, we can apply the formula repeatedly, starting from n = 2.

Using the given formula, we can calculate the values of the sequence as follows:

f(2) = f(2-1) + 4 = f(1) + 4 = 3 + 4 = 7

f(3) = f(3-1) + 4 = f(2) + 4 = 7 + 4 = 11

f(4) = f(4-1) + 4 = f(3) + 4 = 11 + 4 = 15

The values we obtained are: f(1) = 3, f(2) = 7, f(3) = 11, and f(4) = 15.

Comparing these values to the options provided:

A) 3, 9, 11, 13

B) 3, 8, 10, 12

C) 4, 7, 10, 13

D) 3, 7, 11, 15

We can see that option D) 3, 7, 11, 15 matches the values we calculated using the recursive formula. Therefore, the correct answer is option D).

Answers

Answer:

90+30+2x=180

Step-by-step explanation:

2x is an angle, so we need to find its measure

square symbol at corner of triangle means 90 degrees

we know the angle at the top corner is 30 degrees

the sum of all the angles in a triangle is 180 degrees

so the sum of 90 degrees, 30 degrees, and 2x degrees is 180 degrees

translate it to mathematical format: 90+30+2x=180
