Answer:

4. 8.0

5. 27.6

6. 35.5 degrees

Step-by-step explanation:

#4- Cos 48= x/12

0.669131= x/12

x=8.0

Sin 78= 27/x

0.978=27/x

0.978x=27

x=27.6

Tan X= 15/21

tan x= .714

inverse tan= 35.5 degrees

Well we know that:
1-4 stay on the floor,
5-9 it's round up time.
So with that in mind you would round the 9's up and they would round up th 4 to a 5. 5's round up so that would round up the first 4 to a 5.
SO your answer would be 5,000.

A set of weights includes a 10 lb barbell and 8 pairs of weight plates. Each pairof plates weighs 20lbs. If x pairs of plates ar

Leni [432]

It is given that the weight of the barbel is given by:

$f(x)=20x+10$

It says that there are eight pair of weights so x can take values from 0 to 8 and f(x) can take the values as follows:

$\begin{gathered} x=0,f(x)=10 \\ x=1,f(x)=30 \\ x=2,f(x)=50 \\ x=3,f(x)=70 \\ x=4,f(x)=90 \\ x=5,f(x)=110 \\ x=6,f(x)=130 \\ x=7,f(x)=150 \\ x=8,f(x)=170 \end{gathered}$

So the range is:

$\mleft\lbrace10,30,50,70,90,110,130,150,170\mright\rbrace$

Option B is correct.

The range is all the y-values.

(1,0)
(2,2)
(-4,-2)
(-2,-3)

These points are all in the form of (x,y)

The y-coordinates make up the range.

The range is {-3, -2, 0, 2}.

Your answer is A.
