What is this? Please help

Answer:

[tex] m = n = 9\sqrt 2[/tex]

Step-by-step explanation:

Given is a 45° 45° 90° triangle.

So,

[tex]m = \frac{1}{ \sqrt{2} } \times 18 = \frac{1}{2} \times 18 \sqrt{2} = 9 \sqrt{2} \\ \\ n = \frac{1}{ \sqrt{2} } \times 18 = \frac{1}{2} \times 18 \sqrt{2} = 9 \sqrt{2} \\ \\ [/tex]

Equality Properties

Step-by-step explanation:

Step 1: Define equation

3x + 2 = 17

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 17 does indeed equal 17.

∴ x = 5 is a solution of the equation.

Answer:

[tex]f(6) = 15[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \left \{ {{|x - 8| + 6 \ x<4} \atop {15\ x\ge 4}} \right.[/tex]

Required

Find f(6)

From the piecewise function, the value of f(x) is:

[tex]f(x) = |x - 8| + 6[/tex]

If [tex]x < 4[/tex]

And the value of f(x) is:

[tex]f(x) = 15[/tex]

If [tex]x \ge 4\\[/tex]

In f(6), the value of x is 6 and [tex]6 \ge 4[/tex]

So, we make use of

[tex]f(x) = 15[/tex]

Substitute 6 for x

[tex]f(6) = 15[/tex]

Answer:

7 sq rt 2

Step-by-step explanation:

must use pythagorean theorem: square of each leg = square of hypotenuse

7 squared the 7 squared = u squared

49+49=u squared

u = square root of 98, which is sq root of 49 times sq root of 2

Answer:

f(x) = 3x² + 1

Step-by-step explanation:

In this question, we need to find what equations equals to 13 when we plug in 2 to x.

Solve the equations to find which one is true:

f(2) = 2² + 8

= 4 + 8

= 12

---------------

f(2) = 3(2)² + 1

= 3(4) + 1

= 12 + 1

= 13

---------------

f(2) = 2(2)³ + 5

= 2(8) + 5

= 16 + 5

= 21

---------------

f(2) = 2² + 2

= 4 + 2

= 6

You will see that the 2nd equation, f(x) = 3x² + 1, is the only one that equals to 13, which makes it correct.

Answer:

the slope would be 17

Step-by-step explanation:

he earns $17 per hour

you find this by dividing the amount earned by the hours worked

102 / 6 = $17 per hour

187 / 11 = $17 per hour

Answer:

The probability of finding the entry in the period between 30 and 32 minutes is 5%.

Step-by-step explanation:

Given that the time required to find an entry is uniformly distributed between 0 and 60 minutes, it implies that 100% of the chances are in that period of time distributed equally. Therefore, since 100/60 is equal to 1.66, each minute has a 1.66% chance that the entry will be there.

Thus, since between minutes 30 and 32 there are 3 minutes in total (30, 31 and 32), to determine the probabilities of finding the entry in that period it is necessary to perform the following calculation:

1.66 x 3 = X

5 = X

Therefore, the probability of finding the entry in the period between 30 and 32 minutes is 5%.

Answer:

the sample = the 100 times Sheldon brushed his teeth in front of the mirror

Step-by-step explanation:

In statistics, the sample is a small portion of a population that a researcher can study. It should represent a random subset of data from the population. The advantage of using a sample is that the size is smaller than the whole population, which makes it more manageable.

When you study the whole population, you are performing a census. That means that you are not obtaining a sample. In this case, the population would be every time that Sheldon or someone else washes his/he teeth in that bathroom.

Answer:

10+7+.5

Step-by-step explanation: ez >:)

Answer:

Yes

Step-by-step explanation:

8.139 rounded to the nearest tenth would be 8.1 because the tenth place that we’re looking at is the number 1 and the number after it is 3. if the number that is after the tenth place is greater than 5 then the tenth place number goes up. and if the number after tenth place is lower than 5, then we stay the same. since 3 is lower than 5, the tenth place number stays the same making the answer 8.1. hope that helped lol..

Answer: 25

Step-by-step explanation:

20/4=5 so 5 books per month then a total of 5 months so 5x5=25

20 divided by 4 is 5 meaning Jackson read 5 books every month so if he read 20 books in 4 months + 5 more months he read a total of 45 books...

5*5=25

25+20=45

Answer:

The Volume of cylinder is: [tex]\mathbf{Volume=2\pi x^3-5\pi x^2-24\pi x+63\pi }[/tex]

Option B is correct option.

Step-by-step explanation:

We are given:

Volume of cylinder = h = 2x+7

Radius of cylinder = r = x-3

We need to find volume of cylinder

The formula used is: [tex]Volume=\pi r^2h[/tex]

Putting values and finding volume

[tex]Volume=\pi r^2h\\Volume=\pi (x-3)^2(2x+7)\\Volume=\pi (x^2-6x+9)(2x+7)\\Volume=\pi (2x(x^2-6x+9)+7(x^2-6x+9))\\Volume=\pi (2x^3-12x^2+18x+7x^2-42x+63)\\Volume=\pi (2x^3-12x^2+7x^2-42x+18x+63)\\Volume=\pi (2x^3-5x^2-24x+63)\\Volume=2\pi x^3-5\pi x^2-24\pi x+63\pi \\[/tex]

So, The Volume of cylinder is: [tex]\mathbf{Volume=2\pi x^3-5\pi x^2-24\pi x+63\pi }[/tex]

Option B is correct option.

Answer:

49 acres

Step-by-step explanation:

Given that:

Initial coverage = 1200 at midnight

Spread rate = 5√t acres per hour

By how many acres will the fire grow between 6am and 10 am

Hours between (6 - 10) am = 6 hours

Take the integral of the rate function with upper limit = 6 and lower limit = 0

∫5√t dt at t = 6, t = 0

5∫√tdt = 5∫t^1/2 dt at t = 6, t = 0

5 (t^1/2 + 1 / 1/2 + 1) at t = 6, t = 0

5 ( t^3/2 / 3/2) at t = 6, t = 0

5 * 2/3 (t^3/2)

[10/3 *t^3/2] at t = 6, t = 0

(10/3 * 6^3/2) - (10/3 * 0^3/2)

(10/3 * 14.696938) - 0

48.989794

= 49 acres ( approximately)

Answer:

B. ¼.

Step-by-step explanation:

Equation that represents a proportional relationship usually takes the form, y = kx. Where, k is the constant of proportionality.

Therefore, if we are given an equation that represents a proportional relationship, to be y = ¼x, the constant of proportionality is ¼.
