Answer:

l = (3x+5)

Step-by-step explanation:

Given that,

The area of a room, [tex]A=3x^2-x-10[/tex]

The width of the room, [tex]b=(x-2)[/tex]

We need to find the length of the room.

The area of the room is given by :

A = lb

[tex]l=\dfrac{A}{b}\\\\l=\dfrac{3x^2-x-10}{x-2}\\\\l=\dfrac{(x-2)(3x+5)}{x-2}\\\\l=(3x+5)[/tex]

So, the length of the room is equal to (3x+5).

Answer:

Yes.

Answer:

[tex]\tan(x + 40) = 1.842[/tex]

Step-by-step explanation:

Given

[tex]\sin(x + 4) = \cos(3x)[/tex]

Required

Find [tex]\tan(x + 40)[/tex]

In trigonometry

If [tex]\sin(A) = \cos(B)[/tex]

Then: [tex]A + B = 90[/tex]

So, we have:

[tex]\sin(x + 4) = \cos(3x)[/tex]

[tex]3x + x + 4 = 90[/tex]

[tex]4x + 4 = 90[/tex]

Collect like terms

[tex]4x =- 4 + 90[/tex]

[tex]4x =86[/tex]

Solve for x

[tex]x = 86/4[/tex]

[tex]x = 21.5[/tex]

So:

[tex]\tan(x + 40) = \tan(21.5+40)[/tex]

[tex]\tan(x + 40) = \tan(61.5)[/tex]

Using a calculator:

[tex]\tan(x + 40) = 1.842[/tex]

Answer:

#1: 5/8, #2: It is a right triangle, #3 $2: per square foot, #4: 300%

Step-by-step explanation:

#1: If you want the probability of drawing a non-red marble, you need to have the number of non-red marbles divided by the total number of marbles. Since it's a 3 to 5 ratio, and the 5 represents marbles that are white, not red, you can put 5/(5+3), or 5/8 as your answer.

#2: For this one, you need to use the pythagorean theorem, a rule that will be true if it's a right triangle, and false if it's not. It's A² + B² = C², where C is bigger than A and B. To apply this, you can plug 7² + 24² into a calculator, and see whether or not the answer is equal to 25² (which, in this case, it is, meaning that it is a right triangle.)

#3: The idea with this is cancelling out the units until you end up with the units you want. You know how 7897/7897 would still be equal to one, as anything divided by itself is still one? We can use that concept, because multiplying our original value by 1 won't change the value, just the units. Since 1 yard = 3 feet, we can do this: ($18)/(yard²) × (1 yard)/(3 feet) × (1 yard)/(3 feet) = $2/feet²

#4 This one I will use sample values for: let's say our rectangle has a length of 10 inches and a width of 20 inches. That means it's area will be L × W, that is, 10 × 20 = 200 inches². Now lets increase the dimensions by 100%. Our length would become 20 inches, and our width would become 40 inches. That makes L × W = 20 × 40 = 800 inches². Now, to see what percent increase that is from the original, we have to do (800 - 200)/200, that is, 3, or 300%.

Sorry I don't have time to do the last one, but might I suggest that you post the questions individually next time? I just think it might make people less scared to jump into solving one problem than five, so you might get answers sooner =)

Step-by-step explanation:

Giving the following information:

Number of periods= 11 months

Interest per month= $3

To calculate the total amount of interest paid, we need to use the following formula:

Total interest paid= number of periods*interest per period

Total interest paid= 11*3

Total interest paid= $33

Answer:

The number to be added is 81/4

Step-by-step explanation:

To get the number, we look at the coefficient of x

In this case, we have it as -9

we divide this by 2

It gives (-9/2)

We square this value and add it to both sides

This would be

(-9/2)^2 = 81/4

It is this number we will add to both sides of the equation

Answer:

A.) The function is linear.

C.) The height increases at a constant rate of change.E

Step-by-step explanation:

Edge 2022

The function is linear and the height increases at a constant rate of change are the correct statements of the given graph.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Based on the description, it seems that the function is linear because the graph shows a line of dots that increases at a constant rate from 0 to 9 weeks.

Therefore, the following statements apply:

The function is linear.

The height increases at a constant rate of change.

Linear functions are those functions whose graph goes in a straight line. This function has one independent variable and one dependent variable.

The height increases at a constant rate of change. We can see as the time is increasing the height is increasing. We can determine this by slope of graph.

Hence, the function is linear and the height increases at a constant rate of change are the correct statements of the given graph.

g=-1

Step-by-step explanation:

3(g+4)=9

Divide both sides by 3.

g+4=  9/3

Divide 9 by 3 to get 3.

g+4=3

Subtract 4 from both sides.

g=3−4

Subtract 4 from 3 to get −1.

g=−1

Answer:

3(g+4)=9

or, 3(g+4)/3=9/3 [Dividing both sides by 3.]

or, g+4=3

or, g+4-4=3-4 [Subtracting 4 from both sides.]

So, g=-1

Answer: 1/4

Step-by-step explanation:

Since the rectangle is divided into 8 equal parts and two parts are shaded, this simply means that 2 out of 8 parts are shaded which is 2/8.

The fraction that's equvalent to the shaded area of the rectangle will be:

2/8 = (2 × 1) / (2 × 4) = 1/4

The equivalent fraction is 1/4
