Find the missing side. Round your answer to the nearest tenths.

X=

Answer:

f(-1)=0

Step-by-step explanation:

[tex]f(x) = -x^2+x\\\\Now,\\\\f(-1)=-(1)^{2} +(-1)\\\\f(-1)=1-1\\\\f(-1)=0[/tex]

Answer:

-2

Step-by-step explanation:

Since they said  f(-1) we know that x = -1

So we plug in -1 for anything that says x

-1^2 - 1

Now we do 1^2 = 1 then mulitpy by -1

that give us -1

-1^2 = -1

-1 - 1 = -2

Answer:

a 25-7.36

=17.64

b 8.65+4.23-3.5

=12.88-3.5

=9.38

Answer:

a) 17.64

b) 9.38

Step-by-step explanation:

a) 25 - 7.36 = 25 - 7 - 0.36 = 18 - 0.36 = 17.64

b) 8.65 + 4.23 - 3.5 = 8.65 - 3.5 + 4.23 = 5.15 + 4.23 = 9.38

Hope this helps :)

Answer:

Step-by-step explanation:

If 70% passed both, then that means 30% passed either one test, or neither test.

Since 80% passed the first test, we know that 20% of the students failed the first test.

This means that the other 10% of the students came from the 80% that already passed the first test.

These make up 10/80 = 12.5% of the people that passed the first test, meaning your answer is 100-12.5=87.5%

The length of the blade of the windmill will be equal to 7 feet.

We have the equation

[tex]\rm h=7 \ Sin(\dfrac{\pi}{21t})+28[/tex]

At the time 't' = 0, the end of the blade is pointing to the right parallel to the ground meaning it is at the same height as the other end. (Ф = 0°)

So, by calculating the maximum height of this end at  Ф = 90°. we can calculate the length of the blade.

Now, we know that a general model equation of a circular simple harmonic motion is represented as

[tex]\rm y=A\ Sinwt+k[/tex]

Where A is the amplitude that is, maximum displacement from mean to maximum position.

ω is the angular frequency.

Comparing the above equations we can conclude that

A = 7

so the difference in blade's end height at Ф = 0° and Ф = 90° is 7 feet.

Answer:

Yes, (5,5) is a solution of y=x

Step-by-step explanation:

A point is given as a coordinate pair, (x,y). The first number is x and the second number is y. A solution is a pair of numbers that will make the equation true.

To check if the point is a solution, fill in the first number in place of x in the equation. Then fill in the second number for the y.

Here we have the equation:

y = x

Substituting (filling in) we get:

5 = 5 a true statement. So (5,5) IS a solution.

Alternatively, you could graph the equation and verify that the point is on the graph. see image.

15.4 minutes :)

Step-by-step explanation:

We need to turn the percentage into a decimal first :)

27/100 = 0.27

Now we multiply it by 57 to see how much time has gone by!! :)

0.27 x 57 = 15.39

Now to finish, we round!

Step-by-step explanation:

Step-by-step explanation:

Domain of a rational function is everywhere except where we set vertical asymptotes. or removable discontinues

Here, we have

[tex] \frac{x(2x - 3)}{(x + 2)x} [/tex]

First, notice we have x in both the numerator and denomiator so we have a removable discounties at x.

Since, we don't want x to be 0,

We have a removable discontinuity at x=0

Now, we have

[tex] \frac{2x - 3}{x + 2} [/tex]

We don't want the denomiator be zero because we can't divide by zero.

so

[tex]x + 2 = 0[/tex]

[tex]x = - 2[/tex]

So our domain is

All Real Numbers except-2 and 0.

The vertical asymptors is x=-2.

To find the horinzontal asymptote, notice how the numerator and denomator have the same degree. So this mean we will have a horinzontal asymptoe of

The leading coeffixent of the numerator/ the leading coefficent of the denomiator.

So that becomes

[tex] \frac{2}{1} = 2[/tex]

So we have a horinzontal asymptofe of 2

Answer:

60

Step-by-step explanation:

If we look at the picture, we can see that its a right angle having a 90 degree.

We can make a equation with this as we know that m1 and m2 has to equal 90

x + y = 90

Since we know that m2 = 30 we can plug 30 for x

(30) + y = 90

Now we simply moving the 30 to the 90

y = 90 - 30

y = 60

Answer:

Step-by-step explanation:

Eva must subtract 4*3/2=6 from each side to get 4x=2, the divide by 4 to get x=1/2

Another way:

First, divide both sides with 4 to get x+3/2=2. Then subtract 3/2 from each side and we will have x= 2-3/2= 1/2

Answer:

6πm³

Step-by-step explanation:

To work out the volume of a cylinder, use the formula πr²h

Answer:

19,500 people

Step-by-step explanation:

20% of 25,000 is 5,000.

Add 5,000 to 25,000 - this will give you 30,000. That is a 20% increase.

65% of 30,000 is 19,500, thus there are 19,500 people in the stadium.

Answer:

the answer is .....true

Answer:

Answer:

370×1850= 6,84,500

and then

56,950+6,84,500=7,41,450

the population will be 7,41,450

The population of bacteria after 1850 hrs in a colony, if the number of bacteria doubles every 370 hours, is 1822400.

Along with addition, subtraction, and division, multiplication is one of the four basic mathematical operations. In mathematics, multiply refers to the continuous addition of sets of the same size.

Given:

The population of bacteria, P = 56950,

If the number of bacteria doubles every 370 hours then in 1850 hrs = 1850 / 370 = 5,

So, the no doubles 5 times in 1850 hrs,

Now if it doubles 1 time it will be 56950 × 2, and

for 5 times double population will be = 56950 × 2 × 2 × 2 ×2 × 2

P = 1822400

Therefore, the population of bacteria after 1850 hrs in a colony, if the number of bacteria doubles every 370 hours, is 1822400.
