Using the Pythagorean theorem:

KL = sqrt( 8^2 + 5^2)

KL = sqrt( 64 + 25)

KL = sqrt(89)

KL = 9.43

The answer is 9.43

Answer:

His friend took one from 61 and added it to 39. That made it easy to mentally add 40 and 60 to get 100. Then he mentally added 28 to 100 to get 128.

Answer:

Step-by-step explanation:

Answer:

∠x = 32°

∠y = 58°

∠z = 32°

Step-by-step explanation:

∠x = 180° - 148° = 32°  

∠z = 32° because it is vertical to ∠X (32°)

∠y = 90° - 32° = 58°

Answer:

The required sample size is 35.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

Determine the required sample size.

The required sample size is n, which is found when [tex]M = 8[/tex]

The standard deviation of 24 means that [tex]\sigma = 24[/tex]. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]8 = 1.96\frac{24}{\sqrt{n}}[/tex]

[tex]8\sqrt{n} = 1.96*24[/tex]

Simplifying both sides by 8

[tex]\sqrt{n} = 1.96*3[/tex]

[tex](\sqrt{n})^2 = (1.96*3)^2[/tex]

[tex]n = 34.6[/tex]

Rounding up:

The required sample size is 35.

Answer: B. y = tan x

Step-by-step explanation:

The function whose graph is show below will be tan x. Then the correct option is B.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The secant of angle x is not defined, for some value of x. Then the domain of the sec x will be

Domain = R – (2n + 1) π/2

But the graph of the sec x looks like U. Then it is incorrect.

The tangent of angle x is not defined, for some value of x. Then the domain of the tan x will be

Domain = R – (2n + 1)π/2

Then it is correct.

The co-secant of angle x is not defined, for some value of x. Then the domain of the csc x will be

Domain = R – nπ

Then it is incorrect.

The co-tangent of angle x is not defined, for some value of x. Then the domain of the cot x will be

Domain = R – nπ

Then it is incorrect.

Then the correct option is B.

After that, all terms reduce as follows: the [tex]5^{2}[/tex] with the 25 in 50, the s at the numerator with the s in the denominator, and a t from the denominator with one unit from the exponent of t in the numerator.

Answer:

D, 261

Step-by-step explanation:

Divide all of the answer choices by 9. The answer is the one with the whole number. 261/9=29 29=whole number so D is the answer.

Hope this helps! If it did, please give brainliest! It would help a lot! :D

Answer:

261

Step-by-step explanation:

If the farmer used 9 boxes and each had the same number, we need to find the number that's divisible by 9.

There's a great fact - a number is divisible by 9 if its sum of digits is divisible by 9.

Let's use that fact on the answers first:

281 -> 2 + 8 + 1 -> 11 -> 1 + 1 -> 2; not divisible by 9

273 -> 2 + 7 + 3 -> 12 -> 1 + 2 -> 3; not divisible by 9

261 -> 2 + 6 + 1 -> 9; divisible by 9

Please note that we could just say that 11 is not divisible by 9, but I wanted to show that we can do it again - nothing stops us and it still works.

To know why this method works, note that a number ABC is equal to:

100 * A + 10 * B + C = 99 * A + 9 * B + (A + B + C) = 9*(11*A + B) + (A + B + C)

And we know that 9*(11*A + B) is divisible by 9 because it's literally 9 times something. So A+B+C is equal to ABC minus something divisible by 9, and that proves what we needed.

Answer:

df(t)/dt = 10 - 0.8f(t)

Step-by-step explanation:

The net rate of change, df(t)/dt = rate in - rate out

The rate in = rate litter forms on ground = 10 g/cm²/yr

Since f(t) is the amount of litter present at time, t, in g/cm² the rate out = rate of decomposition = the percentage rate × f(t) = 80% per year × f(t) = 0.8f(t) g/cm²/yr

Since df(t)/dt = rate in - rate out

df(t)/dt = 10 - 0.8f(t)

So the desired differential equation is

df(t)/dt = 10 - 0.8f(t)
