Answers

Answer:

F

Step-by-step explanation:

Simplify then graph it, find the x-intercept.

y = 3.75 + 1.5 (x - 1)

y = 1.5x + 2.25

When graphed, the x-intercept is 1.5

So it is, $1.50 per mile

Answer:

F. $1.50 per mile

Step-by-step explanation:

In order to solve this, you can first change it to slope-intercept form to find the slope, or rate of change, easier:

y = 3.75 + 1.5(x - 1) (given)

y = 3.75 + 1.5x - 1.5 (multiply 1.5 by each term in the parenthesis)

y = 2.25 + 1.5x (subtract 1.5 from 2.25)

y = 1.5x + 2.25 (order the terms by exponent value)

In slope-intercept form, the m (slope) of this equation is 1.5, so the rate of change is $1.50 per mile (with an initial fee of $2.25).

A student solved the equation sin2x/cosx=2, 0(greater than or equal)x(greater than or equal)pi, and found an answer of pi/2. Describe the student's error.

Please show all steps.

Answers

Answer:

The student forgot about the double angle identity.

Step-by-step explanation:

sin2x/cosx=2

This is the double angle identity

sin2x=2sin(x)cos(x)

(2sinxcosx)/cosx=2

2sinx=2

sinx=1

x=sin^-1(1)

x=90 degrees OR pi/4

q/6 + 9 > 26
how would i find a solution to this?

Answers

Answer:   Q > 102

===========================================================

Explanation:

We follow PEMDAS in reverse to isolate Q

Q/6 + 9 > 26

Q/6 > 26-9 ... subtract 9 from both sides

Q/6 > 17

Q > 17*6 .... multiply both sides by 6

Q > 102

We can have Q be any value larger than 102.

Note how the inequality sign stays the same the entire time. If we multiplied both sides by a negative number, then the inequality sign would flip; however, we multiplied both sides by a positive number.

Please someone help!! I tried my best to complete this problem but i'm stuck now (also am i even doing it right so far??!);(

Answers

Answer and Step-by-step explanation:

You got everything correct so far except for #4.

4. Yes, it is 1. But it would be in months.

So you would put:

1 month = x

12 months = 1 year.

Since the population increases by 1.5 times a month.

For question number 3.

The equation should be:

[tex]f(x) = 100(1.5)^x[/tex] <- Function

[tex]f(x) = 100(1.5)^{12}[/tex] <- Function when x is 12 months (1 year)

(Put those both the same way I put it.)

It gives you the equation to work with, you just have to plug in the values.

1.5 is in the parenthesis because it needs to be the one that is raised by an exponent.

100 is the initial population, so it stays on the outside.

x is the exponent

The lengths of the legs of a right triangle are 8 yards and 15 yards. What is the length, in yards, of the third side of the triangle?
A.23
B.17
C. 12.7
D.11.5

Answers

Answer:

B

Step-by-step explanation:

By inspection it can' be C or D since they are shorter than the 15 yard side.

Also B is just slightly big than 15, so it is mostly likely incorrect

I would guess A is the answer,      proven to be INCORRECT see below

the correct answer is B. 17 yards

check the answer using the pythagorean theorem

a² + b² = c²

a = 8

b = 15

c = √(64 + 225)

  = √289

 = 17   my guess was wrong!!!!
