The area of a room is represented by the trinomial 3x^2-x-10. If the width of the area is represented by x-2, find the expression that represents the length of the room

Answers

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).

A rectangle is divided into 8 equal parts. Two parts are shaded. What fraction is equvalent to the shaded area of the rectangle.

Answers

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

The number of members in an organization, M, changes as a function of t months. In which situation is M a linear function of t?
The membership doubles every year from the previous year.
1.The membership doubles every year from the previous year.
2.The membership increases by 1% every month from the previous month.
3.The membership decreases by 20 members every month from the previous month.
4.The membership increases by 50 members in each of the six warmest months and decreases by 50 members in each of the other six months.The membership doubles every year from the previous year.

Answers

Answer: D. The membership increases by 50 members in each of the six warmest months and decreases by 50 members in each of the other six months.

Step-by-step explanation: Because it is a linear function it needs to fluctuate so by using process of elimination D is the only answer that would look like a linear function by having that curved line we are looking for in a function.

If using the method of completing the square to solve the quadratic equation x^2-9x+2=0x 2 −9x+2=0, which number would have to be added to "complete the square"?

Answers

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

Find the measure of angle K.

Answers

Answer:

K = 97 degrees

Step-by-step explanation:

The four interior angles of a quadrilateral is always equal to 360 degrees.

127 + 88 = 215

(10x + 7) + (5x + 3) = 15x + 10

360 - 215 = 145

145 = 15x + 10

130 = 15x

9 = x

k = 10x + 7

k = 10(9) + 7

k = 97

given that sin(x+4)=cos(3x)find tan(x+40)to 4 s.f.

Answers

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]
