Answers

Answer 1

Note: Your function is missing some information. It seems your function is

[tex]f\left(x\right)=\frac{-3}{x}+7[/tex].

So, I am solving the question based on the function [tex]f\left(x\right)=\frac{-3}{x}+7[/tex],  because it would still solve your query.

Answer:

Please see the explanation.

Step-by-step explanation:

Given the function

[tex]f\left(x\right)=\frac{-3}{x}+7[/tex]

A function g is the inverse of a function f for y = f(x), x=g(y)

[tex]y=\frac{-3}{x}+7[/tex]

Replace x with y

[tex]x=\frac{-3}{y}+7[/tex]

solve for y

[tex]y=-\frac{3}{x-7}[/tex]

so the inverse of [tex]f\left(x\right)=\frac{-3}{x}+7[/tex] will be:

[tex]f^{-1}\:\left(x\right)=-\frac{3}{x-7}[/tex]

Finding the domain of [tex]f^{-1}\:\left(x\right)=-\frac{3}{x-7}[/tex]

As we know that domain is the set of the possible input values where the function is defined.

so the function domain must be: [tex]x<7\quad \mathrm{or}\quad \:x>7[/tex]

Therefore,

[tex]\mathrm{Domain\:of\:}\:-\frac{3}{x-7}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x<7\quad \mathrm{or}\quad \:x>7\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:7\right)\cup \left(7,\:\infty \:\right)\end{bmatrix}[/tex]

X, Y and Z form the vertices of a triangle, where ∠ YXZ = 68°, XY = 7.3m and XZ = 8.3m. Calculate the area of the triangle. Round your answer to 1 DP.

Answers

Answer: Area = 28.2m²

Step-by-step explanation: The triangle YXZ is shown in the figure below.

Area of a triangle is calculated by the formula:

[tex]A=\frac{1}{2} (base*height)[/tex]

According to the figure, the base of this triangle is b = 8.3m.

Height is a perpendicular line created from one side and intersecting the opposite angle.

To determine the height, use trigonometric relations to angle 68:

[tex]sin(68)=\frac{h}{7.3}[/tex]

h = 7.3*sin(68)

h = 7.3*0.93

h = 6.8

Now, area of triangle YXZ is

[tex]A=\frac{1}{2} (8.3*6.8)[/tex]

A = 28.2

Area of triangle YXZ is 28.2m².

Together, teammates Pedro and Ricky got 2675 base hits last season. Pedro had 277 more hits than Ricky. How many hits did each player​ have?

Answers

Answer:

1199 for ricky, 1476 for Pedro

Step-by-step explanation:

2675-277=2398

2398 / 2 = 1199

each player had 1199 bases, pedro however, had 277 more bases than ricky

1199 + 277 = 1476

By solving a system of equations, we conclude that Ricky has 1,199 base hits, and Pedro has 1,476 base hits.

How many hits did each player​ have?

Let's define the variables:

P = base hits of Pedro last season.R = base hits of Ricky last season.

Then we have that the total number of base hits last season is 2675, so we have:

P + R = 2675

We also know that Pedro has 277 more hits than Ricky, then:

P = 277 + R

To solve these equations, we can replace the second equation into the first one:

P + R =  2675

(277 + R) + R = 2675

2*R = 2675 - 277 = 2,398

R = 2,398/2 = 1,199

So we conclude that Ricky has 1,199 base hits, and Pedro has 1,476 base hits.

The perimeter of a rectangular garden is 338 m.
If the width of the garden is 74 m, what is its length?

Answers

Answer:

l=95

Step-by-step explanation:

Perimeter is all the sides add up. So the equation if you know two of the sides, it should be: 338=(2*74)+(2*l)

Answer:

Step-by-step explanation:

the perimeter is 2w plus 2l

so 338 = 74(2)+2l

338 = 148+2l

190=2l

l=95

your length would be 95 m

Edan is thinking of selling the 6 tickets she bought. Her goal is to earn $100 after selling the tickets. Using the equations from part a) and b), how much should Edan sell each ticket for, if she wants to make a profit of at least $100?

Answers

Answer:

a) $21

b) $133.75

c) $233.75

Step-by-step explanation:

Edan buys 3 tickets to a concert. When the delivery charge of $7.75 per order is added to the cost of the tickets, the total cost is $70.75.

A) Create an algebraic equation for this problem. Use the equation to determine the cost of each ticket. Verify your solution.

Let the number of tickets be represented by x

The equation is:

3x + 7.75 = 70.75

3x = 70.75 - 7.75

3x = 63

x = 63/3

x = $21

Each ticket cost $21

B) Olivia is Edan's cousin. Olivia has asked Edan to purchase tickets for her friends as well. Edan has now purchased 6 tickets in total. Use an algebraic equation to determine the total cost to Edan?

1 ticket cost = $21

Let the number of tickets be represented by x

Hence, the equation is

21x + $7.75

21 × 6 + $7.75

= 126 + $7.75

= $133.75

C) Olivia has come down with the flu, and her friends no longer want to attend the concert. Edan is thinking of selling the 6 tickets she bought. Her goal is to earn $100 after selling the tickets. Using the equations from part a) and b), how much should Edan sell each ticket for, if she

Profit = Selling price - Cost Price

Cost price = $133.75

Profit = $100

Selling price = Cost price + Profit

Selling price = $133.75 + $100

= $233.75
