WILL GIVE BRAINLIEST AND 5 STARS AND THANKSEnter The Range Of Values For X 3 &lt; X &lt; ?

Answers

Answer 1

Answer:

3 < x < 7

Step-by-step explanation:

From the diagram; |AB| = |AC|

The length AB is calculated as;

[tex]Sin\ 52^o = \frac{|BD|}{|AB|} \\\\|AB| = \frac{|BD|}{Sin\ 52^o} \\\\|AB| = \frac{12}{Sin\ 52^o} \\\\|AB| =15.228 \ m[/tex]

The length CD is calculated as;

[tex]Sin \ 31^o = \frac{|CD|}{|AC|} \\\\|CD| = |AC| \ \times \ Sin \ 31^o \\\\|CD| = 15.228 \ \times \ 0.515\\\\|CD| = 7.84[/tex]

|CD| = 2x - 6

2x - 6  = 7.84

2x = 7.84 + 6

2x = 13.84

x = 13.84 / 2

x = 6.92

x ≅ 7

Thus, 3 < x < 7

HAPPY?????

Answers

Answer:

-3x - 18

Step-by-step explanation:

Use the distributive property.

-3(x + 6) = (-3)(x) + (-3)(6) = -3x - 18

Answer:

-3x-18

Step-by-step explanation:

Use the distributive property to simplify

-3(x+6)

(-3*x)+(-3*6)

-3x+(-18)

-3x-18

Sally launches a rocket off of a platform. The height of the rocket, in meters, can be modeled by the function, h(x) = -5(x - 3)2 + 56, where x is in seconds. o What is the height of the platform? o What is the maximum height the rocket reaches? o How long does it take to reach this height?

Answers

Answer:

Time = 3secs

Max height = 56m

Step-by-step explanation:

Given the height reached by the rocket modeled by the equation;

h(x) = -5(x - 3)² + 56 where;

x is in seconds

The rocket velocity at its maximum height is zero.

Hence dh/dx = 0

dh/dx = 2(-5)(x-3)

dh/dx = -10(x-3)

Since dh/dx = 0

0 = -10(x-3)

0 = -10x + 30

10x = 30

x = 3secs

Hence it takes 3 secs to reach the maximum height.

Get the maximum height reached by the rocket. Substitute x = 3 into the equation given;

Recall that:

h(x) = -5(x - 3)² + 56

If x  = 3

h(3) = -5(3 - 3)² + 56

h(3) = 0 + 56

h(3) = 56

Hence the maximum height that the rocket reaches is 56m

Write an equation of the line that goes through the point (6, 12) and has a slope of 2 3 .

Answers

Answer:

3y = 2x + 24

Step-by-step explanation:

The correct question is as follows;

Write an equation of the line that goes through the point (6, 12) and has a slope of 2/3

Solution

Here, we have a point and a slope, and we want to write the equation of the line

The method we shall use here is the point slope method

Mathematically, that will be;

y-y1 = m(x-x1)

(x1,y1) = (6,12)

m = 2/3

y-12 = 2/3(x-6)

3(y-12) = 2(x-6)

3y-36 = 2x - 12

3y = 2x -12 + 36

3y = 2x + 24

Nicole rented a scooter while she was on vacation. She paid an initial rental fee of $50 plus a daily fee of $ 25 each day. The total cost was for the rental was $300. How many days did Nicole rent the scooter

Answers

Answer: Nicole rented the scooter for 10 days.

Step-by-step explanation:

50 + 25 = 75 (Day 1)

75 + 25 = 100 (Day 2)

100 + 25 = 125 (Day 3)

125 + 25 = 150 (Day 4)

150 + 25 = 175 (Day 5)

175 + 25 = 200 (Day 6)

200 + 25 = 225 (Day 7)

225 + 25 = 250 (Day 8)

250 + 25 = 275 (Day 9)

275 + 25 = 300 (Day 10)

Answers

Answer:

6,250$ is the overhead for department a

The distribution of overhead to Department A based on sales is $6250.

What is an overhead expense?

A recurring cost of running a firm is referred to as overhead or overhead charge. While operating expenses like material and labor, overheads could easily be linked to or recognized with any one revenue unit.

They are operating costs for a business that cannot be connected to the creation or production of a good or service. They are really the costs a business must pay to remain open, independent of how successful it is.

Department A has sales of $200,000

Department B has sales of $600,000

Therefore the ratio between the two departments will be:

200000: 600000

= 1 : 3

The overhead expense for both the department combined are $25,000

The share of department A will  be at

= 25000 * (1/4)

= $6250
