What you need to do is look at the number in front of all the variables.

a) 1
Explanation: how many ys are there? 1 is the answer. (The reason we don't NEED to write 1 before a variable is for the same reason that when I say I have 1 thing, I can just say I have a thing. I don't need to include the 1)

c) 6
Explanation: how many sts are there? 6 is the answer.

d) -15
Because a variable to the '0' power equals 1, we can write this as -15x^0 and then we can come to -15(1) which is just -15. We write is with the x^0 so that we can ask, how many x^0 are there? -15 is the answer.

e) -1
Explanation: just like the coefficient of JUST dh would be 1, the coefficient of NEGATIVE dh would be -1

f) 1
Explanation: how many bcs are there? The answer is 1.


Best of luck! :)

Please help!!!!!!!!!!!!!!!!!!!!!!!!
brilliants [131]

Answer: P=47 inches

Step-by-step explanation:

First, you have to find the other side lengths. Two of the sides are equal to 20 because this is a rectangle. The first blank would be 20 because 20 times the other side length is equal to 70. Then you would divide 70 by 20 which would equal x. x would equal 3.5 in. Then the perimeter would be:

2(20)+2(3.5)=P

P=47 inches

stepan [7]

Answer: Mean=4.11

Median=4.44

Step-by-step explanation:

Using a graphing calculator, enter the values into the first list.  Then run one-variable statistics on the list.

By hand, to find the mean, add together all of the values:

3.25+3.25+3.66+3.83+4.57+4.52+4.74+4.69+4.44 = 36.95

Divide by the total number of data points, 9:

36.95/9 = 4.11

To find the median, order the data from least to greatest:

3.25, 3.25, 3.66, 3.83, 4.44, 4.52, 4.57, 4.69, 4.74

The middle number is 4.44

A ball is tossed between three friends. The first toss is 8.6 feet, the second is 5.8 feet, and the third toss is 7.5 feet, whic
algol13

Answer:

The angles are 79.45, 59.02 and 41.53 degrees to the nearest hundredth.

Step-by-step explanation:

We have a triangle with sides of length 8.6, 5.8 and 7.5 feet.

Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:

cos X =  (8.6^2 - 5.8^2 - 7.5^2) / ( -2*5.8*7.5)

=  0.18310

X =  79.45 degrees.

We can now find another angle using the sine rule:

8.6 / sin 79.45 =  7.5/ sin Y

sin Y = (7.5 * sin 79.45) / 8.6

Y = 59.02 degrees

So the third angle = 180 - 79.45 - 59.02

= 41.53 degrees.
