The table represents the function f (x) = 3x-1
Reika [66]

Answer:

a=-16, b=11, c=23

Step-by-step explanation:

The function that represents the table is

f(x) = 3x - 1

We substitute x=-5 to find the value of a.

a = f( - 5) = 3( - 5) - 1

We evaluate to obtain:

a =  - 15 - 1 =  - 16

To find the value of b, we substitute x=4,

We get:

b = f(4) = 3 \times 4 - 1 \\ b = 12 - 1 \\ b = 11

To find c, we plug in x=8,

c = f(8) = 3(8) - 1 \\ c = 24 - 1

c = 23

Answer: the area of the triangle is 23.4 cm²

Step-by-step explanation:

The given triangle is not a right angle triangle. Since two sides and one angle are known, we can either apply the Heron's formula or the Sine formula which is expressed as

Area of triangle = 1/2abSinC

Where a and b are the sides of the triangle and C is the given angle. Therefore,

Area = 1/2 × 8.2 × 6.4 × Sin63

Area = 1/2 × 8.2 × 6.4 × 0.8910

Area = 23.4 cm² to the nearest tenth.
