Answers

Answer 1

Answer:

Image 1

1. x = 4

f(4) = (- 3*4 + 1) / 6 = -11/6

2. x = -2/3

f(-2/3) = -3*(-2/3) + 10 = 2 + 10 = 12

3. x = -5

f(-5) = [tex]\sqrt{-(-5)/20}[/tex] = [tex]\sqrt{5/20}[/tex] = [tex]\sqrt{1/4}[/tex] = 1/2Image 2To work out the inverse, substitute f(x) with x and x with y, then solve for y. The new function is the inverse of the given.

1. f(x) = 5x + 3

x = 5y + 3 ⇒ 5y = x - 3 ⇒ y = (x - 3)/5f⁻¹(x) = (x - 3)/5

2. f(x) = 4/5x

x = 4/5y ⇒ y = 5/4xf⁻¹(x) = 5/4x

3. f(x) = (2x + 7)/4

x = (2y + 7)/4 ⇒ 2y + 7 = 4x ⇒ 2y = 4x - 7 ⇒ y = 2x - 3.5f⁻¹(x) = 2x - 3.5

4. f(x) = (2x + 7) /(x + 3) = 2 + 1/(x + 3)

x = 2 + 1/(y + 3) ⇒ x - 2 = 1/(y + 3) ⇒ y + 3 = 1/(x - 2) ⇒ y = (1 - 3x + 6)/(x - 2) ⇒ y = (7 - 3x)/(x - 2)f⁻¹(x) = (7 - 3x)/(x - 2)

5. f(x) = [tex]\sqrt{x - 4}[/tex]

x = [tex]\sqrt{y - 4}[/tex] ⇒ x² = y - 4 ⇒ y = x² + 4f⁻¹(x) = x² + 4

Answers

Answer:

What grade is this 12th?

Step-by-step explanation:

The equivalent expression for the expression given; (( 5/7 )² × (1/3)-³)-¹ is; (7/5)² • (1/3)³.

What is the equivalent expression for the given expression?

It follows from the task content that the expression which is equivalent to that which is given is to be determined.

here, we have,

Hence, since the given expression is; (( 5/7 )² × (1/3)-³)-¹;

It follows from the power of powers law of indices that we have;

( 5/7 )-² • (1/3)³

Also, according to the negative exponent law of indices; we have;

(7/5)² • (1/3)³.

On this note, the required equivalent expression is; (7/5)² • (1/3)³.

A 45 degree angle is 1/8 of a circle, so keep that in mind for later. You're looking for the circumference of that 1/8 fence, so you have to use the formula, circumference/diameter=pi. Now, the problem gives you half the diameter, a.k.a the radius, so double it to get 44 ft. then, you multiply that by 3.14 (pi) to get 138.16. Now take the 1/8, from before, of the circumfrence and you get your final answer, 17.27 ft!

What is the interest you will pay if you borrowed $120 at 5% interest for 6 years?

Answers

Answer:

Hope this helps!

Step-by-step explanation:

We will need the loan payment formula:

That formula is really complex and we expect you to solve it.

Your monthly payment would be $1.93 per month for 6 years making the TOTAL loan cost 1.93 * 12 * 6 = 138.96

Since the principal you borrowed is $120 the total interest =

(138.96 minus 120.00) which equals $18.96

Answer:

The answer is 36

Step-by-step explanation:

120*0.05=6

6.6=36

an employer pays three workers x,y,z a total amount of 6100 a month. x is paid 125% of the amount y is paid; which represent 80% of the amount z is paid. how much does x receive a month

Answers

Answer: 2178.57

Step-by-step explanation:

Given

The employer pays 6100 total money a month

Suppose z receives A amount

Amount paid to y is 80% of A i.e.

[tex]\Rightarrow y=0.8A[/tex]

Amount paid to x is 125% of y i.e.

[tex]\Rightarrow x=1.25y=1.25\times 0.8A=A[/tex]

The Sum of their total money must be 6100

[tex]\Rightarrow A+0.8A+A=6100\\\Rightarrow 2.8A=6100\\\Rightarrow A=2178.57[/tex]

Amount receive by x is 2178.57

Identify the distance between points (−1,7,10) and (6,−3,2), and identify the midpoint of the segment for which these are the endpoints. Round to the nearest tenth, if necessary.

Answers

Answer:

d ≈ 14.6 units; M (2.5, 2, 6)

Step-by-step explanation:

Using the distance formula for 3-D dimensions, you get the √(213) which equals 14.6

Then, using the midpoint formula for 3-D dimensions, you find the coordinates 2.5 for x, 2 for y, and 6 for z.
