Answer:

It's C

Step-by-step explanation: How far is it from -2 to -8 horizontally?

They are 6 apart, right?

How far is -4 to 4 vertically? 8.

__________________________________________________________

6^2 + 8^2 = c^2

36 + 64 = c^2

c = 100 = 10

So in short yea...it's C UwU

Consider the experiment of flipping three coins at the same time. What is the probability of getting a heads on each of the thre

slamgirl [31]

Answer:

0.125 is the probability of getting a heads on each of the three coins on the one toss of the three coins.

Step-by-step explanation:

We are given the following in the question:

Event: flipping three coins at the same time

We can write the sample space as:

S:{TTT, THH, HTH, HHT, TTH, HTT, THT, HHH}

We define probability as

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

We have to evaluate the probability of getting a heads on each of the three coins on the one toss of the three coins

$P(HHH) = \dfrac{1}{8}=0.125$

0.125 is the probability of getting a heads on each of the three coins on the one toss of the three coins.

Missouri has a shape that is similar to a trapezoid with bases of about 198 miles and 276 miles and a height of about 270 miles.

tiny-mole [99]

Answer:

63,990 mi²

Step-by-step explanation:

We can find the answer by using the formula for the area of a trapezoid and putting in the given numbers.

A = (1/2)(b1 +b2)h . . . . where b1, b2 are the base lengths; h is the height

A = (1/2)(198 mi +276 mi)(270 mi)

A = 63,990 mi²

___

Comment on the area of Missouri

This estimate is about 8.2% low.

If f(x)=k (square root)2+x, and f^-^1 (-15)=7, what is the value of k

horrorfan [7]

There's a bit of ambiguity in your question...

We know that $f^{-1}(-15)=7$ , which means $f(7)=-15$ .

I see three possible interpretations:

• If $f(x)=k\sqrt2+x$ , then

$f(7)=-15=k\sqrt2+7\implies k\sqrt2=-22\implies k=-\dfrac{22}{\sqrt2}=11\sqrt2$

• If $f(x)=k\sqrt{2+x}$ , then

$f(7)=-15=k\sqrt{2+7}\implies -15=3k\implies k=-5$

• If $f(x)=\sqrt[k]{2+x}$ , then

$f(7)=-15=\sqrt[k]{2+7}\implies-15=9^{1/k}\implies\dfrac1k=\log_9(-15)$

which has no real-valued solution.

I suspect the second interpretation is what you meant to write.
