Answer:

x = 11.74739484

Step-by-step explanation:

To solve this problem, you can use trig functions. We are given an angle and the side next to it, and we are looking for the side opposite it. The perfect trig function to use for this would be tangent:

tan(θ) = opposite / adjacent

We can substitute the values we already have:

tan(40) = x / 14

x = 14 * tan(40)

We can evaluate this using a calculator and get:

x = 11.74739484

Answer:

X=86/17

Step-by-step explanation:

Answer:

x=46/17

Step-by-step explanation:

Let's solve your equation step-by-step.

3/ 4 (x−2)+ 1/ 3 (2x+5)=4

Step 1: Simplify both sides of the equation.

3/ 4 (x−2)+ 1/ 3 (2x+5)=4

( 3/ 4 )(x)+( 3/ 4 )(−2)+( 1/ 3 )(2x)+( 1/ 3 )(5)=4 (Distribute)

3/ 4x+ −3/ 2 + 2/ 3 x+ 5/ 3 =4

( 3/ 4 x+ 2/ 3 x)+( −3/ 2 + 5/ 3 )=4 (Combine Like Terms)

17/ 12 x+ 1/ 6 =4

17/ 12 x+ 1/ 6 =4

Step 2: Subtract 1/6 from both sides.

17/ 12 x+ 1/ 6 − 1/ 6 =4− 1/ 6

17/ 12 x= 23/ 6

Step 3: Multiply both sides by 12/17.

( 12/ 17 )*( 17/ 12 x)=( 12/ 17 )*( 23/ 6 )

x= 46/ 17

Answer:

  D, B

Step-by-step explanation:

Price per pound is found by dividing dollars by pounds.

  Store A: $9/(3 lb) = $3.00 /lb

  Store B: $9.75/(3 lb) = $3.25 /lb

  Store C: $12.40/(4 lb) = $3.10 /lb

  Store D: $14.50/(5 lb) = $2.90 /lb

Part A: The lowest price per pound is $2.90 per pound at store D.

Part B: The highest price per pound is $3.25 per pound at store B.

h(x)=-x-1

let y =-x-1

interchanging role of x & y

x=-y-1

y=-x-1

h-¹(x)=-x-1

again

f(x)=(2-3x)/2

let

y=(2-3x)/2

interchanging role of x & y

x=(2-3y)/2

2x-2=-3y

y=(2-2x)/3

f-¹(x)=(2-2x)/3

Given function are not inverse of each other.

10.

f(x)=-x+3

let y=-x+3

interchanging role of x & y

x=-y+3

y=3-x

f-¹(x)=-x+3

equal to g(x)=-x+3

Given function are inverse of each other.

Answer:

Step-by-step explanation:

Call h(x) = y (It's easier to see).

y = -x - 1

The first step is always to interchange x and y

y = -x - 1

-x = y - 1

Solve for y

-x + 1 = y

If I understand the question, these two (f(x) and h(x)) are not inverses.

10 is a bit tricky. An inverse can invert into itself: This is called an involution. But if they are differently labeled, I'm not sure. I don't think that this is exactly what is men by an involution. Something like y = x would be. But you have 2 different inverses. I'm not sure that this qualifies.

y = x + 3      

g = x + 3

x = y + 3

x - 3 = y

Answer:

Table B

Step-by-step explanation:

1. The Agent Earned $6,303  

First, the real estate agency will earned 5.5%

5.5/100 * $382,000 = $21,010

Then, the agent earns 30% of $21,010

30/100 * $21,010 = $6,303

2. Basically, we're setting up an equation where Option A and Option B are the same amount.

For option A, you are making 23 dollars each hours, for 40 hours. (40*23)

For option B, you are making 4% of your sales. We're looking for how much she sells, so we can write that as x. (.04x)

Set the 2 options as equal and solve for x.   so x is  920(.04x

sorry if wrong it was really hard

3. If 90% are women, 10% are men.

If x is the total amount of people.

.1x = 320

Solve x from here.

Answer:

300a + 450b ≤ 6000

Step-by-step explanation:

Given:

Cost of electric mower = $300

Cost of gas mower = $450

Total number of mower = 25

Cost of total mower is at least = $6,000

Find:

Number of each mower equation

Computation:

Number of electric mower = a

Number of gas mower = b

So,

Equations

a + b ≤ 25 ........ Equation 1

300a + 450b ≤ 6000 .......  Equation 1

Answer:

144°

Step-by-step explanation:

First, find the area of the circle, with the formula A = [tex]\pi[/tex]r²

Plug in 10 as the radius, and solve

A = [tex]\pi[/tex]r²

A = [tex]\pi[/tex](10²)

A = 100[tex]\pi[/tex]

Using this, create a proportion that relates the area of the sector to the degree measure of the arc.

Let x represent the degree measure of the arc of the sector:

[tex]\frac{40\pi }{100\pi }[/tex] = [tex]\frac{x}{360}[/tex]

Cross multiply and solve for x:

100[tex]\pi[/tex]x = 14400[tex]\pi[/tex]

x = 144

So, the degree measure of the sector arc is 144°

Answer:

We know that

Area = πr²

Area = 3.14 × (10)²

Area = 314/100 × 100

Area = 314 cm²

Now

40π/314 = x/360

40 × 3.14/314 = x/360

125.6/314 = x/360

0.4 = x/360

0.4 × 360 = x

144 = x

Answer:

y = - [tex]\frac{1}{4}[/tex] (x - 1)²(x + 2)(x + 6)

Step-by-step explanation:

The roots from the graph are

x = - 6 , then factor is (x + 6)

x = - 2 , then factor is (x + 2)

x = 1 ( multiplicity 2 ) , then factor is (x - 1)² then

y = a(x - 1)²(x + 2)(x + 6) ← a is a multiplier

To find a substitute any point on the graph into the equation

Using (0, - 3 ), then

- 3 = a(- 1)²(2)(6) = 12a ( divide both sides by 12 )

- [tex]\frac{1}{4}[/tex] = a

Then

y = - [tex]\frac{1}{4}[/tex] (x - 1)²(x + 2)(x + 6)

Answer:

y = .01x * 2^x

y = 50000x
