Given f(x) = x ^ 2 - (3x + 8) Find f(1)

Answer:

Slope = 4

Step-by-step explanation:

The slop of the line is going to be rise over run.

So take where it the y value is 20 as [tex]y_1[/tex], and where it hits about 32 as value [tex]y_2[/tex].

You have you x value when y1 as 5 and x value at yw as 8.

So what you will do here is

[tex]\frac{y_2 - y_1}{x_2-x_1}[/tex]

[tex]\frac{32-20}{8-5}[/tex]

[tex]\frac{12}{3} = 4[/tex]

So your slope is 4.

Answer:

0.90 seconds

Step-by-step explanation:

We will see that one complete revolution takes (2π/7) seconds.

Here we have the function:

f(x) = 33sin(7x−π/12) + 33

The time needed to do a full revolution is given by the period of the function.

Remember that:

sin(x) = sin(x + 2π).

Then:

sin(7x−π/12) = sin(7*(x + T) −π/12)

Then we must have:

2π = 7*T

Where T is the period.

Solving for T, we have:

2π/7 = T

This means that one complete revolution takes (2π/7) seconds.

Answer:

5 in by 8 in

Step-by-step explanation:

Given that :

Area, A of rectangle = 40 in²

Let

height = x

Base = 2x - 2

Area of rectangle = L * B

40 = x * (2x - 2)

40 = 2x² - 2x

2x² - 2x - 40 = 0

x² - x - 20 = 0

x² - 5x + 4x - 20 =0

x(x - 5) +4(x - 5) = 0

x - 5 = 0 or

x + 4 = 0

x = 5 or x = - 4

X cannot be negative

X = 5

Height = 5

Base = 2*5 - 2 = 8

Answer:

Let's denote students in D = in the drama club , S = in a sports team

P(D) = 85/330

P(S) = 200/330

P(D and S) = 60/300

P(D or S) = P(D) + P(S) - P(D and S)  = 85/330 + 200/330 - 60/330 = 15/22

P(neither D nor S) = 1- 15/22 = 7/22

Step-by-step explanation:

Answer:

First we have to found all the clothes that the manufacturer produces in 8 hours,

As given    120 clothes = produce in 1 hour

                  X clothes  = produce in 8 hour

By cross multiplication, we get

X= 120*8

X= 960  total clothes produced in 8 hours

As also given that in each hour 5 clothes damaged ,so we can write as

 5 clothes = damaged in 1 hour

Y clothes = Damaged in 8 hour

By cross multiplication we get

Y=  40 clothes damaged in 8 hour

So the total clothes that manufacturer produce with out damage clothe will be ,

Total normal clothes = X-Y   = 960 - 40  = 920 clothes

Answer:

x = -3

Step-by-step explanation:

To answer this question, you should first remember that the inside angles of a triangle will always add up to 180 degrees. Therefore, we can make an equation and solve it form there:

55 + 54 + (x + 74) = 180

We add like terms:

109 + (x + 74) = 180

Continue adding like terms:

183 + x = 180

Next, we dubtract to siolate the "x" variable:

x = -3

Hope this helps :)

x=-3

Step-by-step explanation:

To start off, you're going to want to know and understand that all the angles of triangle equal 180 degrees.

Now that we know a triangle equals 180 degrees, lets make an equation. This is equation can be 55+54+74+x=180.

Now, lets combine the like terms in the equation. The equation now becomes 183+x=180.

From here, we subtract 180 from both sides, which would get us x=-3.

To double check that this is correct and that it works, you can plug in the -3 where the x would be.

I hope this helped!! Let me know if you have any further questions.

Answer: X=4 Y=-6

Step-by-step explanation:

Well we know that y= -4x+10

So we can input that into the bottom equation

2x +2(-4x+10) = -4

2x +-8x+20=-4

-6x + 20= -4

-6x = -24

x = 4

We also have to find the value of Y

y=-4(4)+10

y= -16 + 10

y=-6

Answer:

Step-by-step explanation:

2x + 2y = -4

Substitute (-4x+10) for y:

2x + 2(-4x+10) = -4

2x -8x + 20 = -4

-6x = -24

x = 4

Add the equations together will get you:

4x=0

Divide the 0 by 4 to get the x alone will get you

x=0

Answer:

There's one solution

(0,5)

Step-by-step explanation:

There's one solution

We can tell this is true because of the 3x in the second on and just hte x in the first. If you look closely you'll see the coefficents for the x values is the only difference between the two.

Let's now solve

We need to get a positive variable by itself

let's take x+y=5 and solve for y

x-5= -y

y= -x+5

We can then plug this y value into the other equation

3x-(-x+5)= -5

3x+x-5= -5

4x= 0

x=0

Let's then plug this value in for x into any of the beginning equations

0+y=5

y=5

Answer:

closest to 1

Step-by-step explanation:

The given fraction is converted into decimal to find the closest value as 1.

A fraction is a number written in the form a / b, where a and b are integers and b ≠ 0.

The number a is called as the numerator and b is the denominator.

The given fraction is 17/21.

It can be written in decimal as below,

⇒ 17/21 = 0.809

Now, the given decimal can be compared with 0, 1/2 and 1 as follows,

0.89 > 0, 1/2 and 0.89 < 1

Which implies that it is closest to 1.

Hence, the given fraction 17/21 is closest to the integer 1.
