<h3>Answer:  an = 6n - 15   (Choice C)</h3>

======================================================

Explanation:

This sequence is arithmetic

The first term is a = -9

The common difference is d = 6 since we're adding 6 to each term to get the next one (eg: -3+6 = 3 or 3+6 = 9 or 9+6 = 15)

Plug those values into the arithmetic nth term formula below

an = a + d*(n-1)

an = -9 + 6*(n-1)

an = -9 + 6n-6

an = 6n - 15

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

As a check, let's plug in something like n = 1

an = 6n - 15

a1 = 6*1 - 15

a1 = 6 - 15

a1 = -9

We see that the 1st term is -9, which matches the sequence given

Now let's plug in n = 2

an = 6n - 15

a2 = 6*2 - 15

a2 = 12 - 15

a2 = -3

The 2nd term is -3. This also matches.

I'll let you check the other values of n to confirm the answer.

Label the parts of the triangle.<br> leg<br> leg<br> altitude<br> hypotenuse<br> right angle
andriy [413]

Answer: See Below

Step-by-step explanation:

One part we can label right off the bat is right angle. It is denoted with the red box. It forms a 90° angle, which is a right angle. At the very top pointing to the right angle, is right angle.

Altitude is another way of saying height. It is how tall the triangle is. The line that shows how tall the triangle is, is the line going down the triangle in the middle. That line is altitude.

Hypotenuse is the longest side of the triangle. It is also located directly across the right angle. Looking at the right angle, the bottom line is the hypotenuse.

Since we have 2 sides left, they are obviously the legs of the triangle.

Alicia wants to bake a cake with ⁹/10 grams of flour.However,she only has ⅓ grams of flour she needs.How much does she have?
natali 33 [55]

Answer:

We know that:

She needs 9/10 grams of flour for the cake (this quantity does not make a lot of sense, maybe is written incorrectly, but is the only info we have, so let's solve the problem with this)

She only has 1/3 of the amount she needs.

How much flour does she have?

Well, she needs 9/10 grams, and she has one-third of that.

Then she has (1/3) times (9/10) grams, this is:

F = (1/3)*(9/10) grams

F = (1*9)/(3*10) grams

F = 9/30 grams

That is the amount of flour that she has.

A man and a woman agree to meet at a certain location about 12:30 p.m. if the man arrives at a time uniformly distributed betwee
Svetllana [295]
We define the spaces of the man and the woman's independent arrivals.
In this case, 
f(man) = 1 (45-15) = 1/30
f(woman)=1/(60-0)= 1/60
f(man)*f(woman) = 1/1800

Probability = P 
P (man-woman)< 5 = 1/1800* integral of (y ) with limits of (x+5) and (x-5) from 45 to 15. 
P (man-woman) <5 = 1/6
