What is the value of c, correct to one decimal place?
(view picture prior to question)

a.4.6

b. 3.2

c. 2.8

d. 1.2

Option (b) is correct.

The value of  c to one decimal place is 3.2

Step-by-step explanation:

Given : A triangle with some measurements are given.

We have to find the measure of side c.

Consider the given triangle ABC,

Using Laws of cosine,

a, b, c are the sides of a triangle and C is the angle opposite to side c.    

then,

So, Taking square root both side, we have,

Here, a = 7 ,

b = 5

and C = 24.63°          

Substitute, we have,

Simplify, we have,

c = 3.22

Thus, The value of  c to one decimal place is 3.2

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
