Answer:

Input - Output

2 - $290

12 - $690

24 - $1170

Step-by-step explanation:

Cost after n months:

The cost after n months is given by the following function:

C(n) = 40n + 210

After 2 months:

This is C(2). So

C(2) = 40(2) + 210 = 80 + 210 = 290

After 12 months:

This is C(12). So

C(12) = 40(12) + 210 = 480 + 210 = 690

After 24 months:

This is C(24). So

C(24) = 40(24) + 210 = 960 + 210 = 1170

Table:

Input - Output

2 - $290

12 - $690

24 - $1170

Find the area of the triangle SHOW WORK
kykrilka [37]

Answer:

The area of triangle is 1263.6 mm².

This is an Equilateral triangle.

Step-by-step explanation:

Given that the area of triangle formula is A = 1/2×base×height. So you have to substitute the values into the formula :

area =  \frac{1}{2}  \times base \times height

Let base = 54mm,

Let height = 46.8mm,

area =  \frac{1}{2}  \times 54 \times 46.8

area =  \frac{1}{2}  \times 2527.2

area = 1263.6 \:  {mm}^{2}

This is the <u>E</u><u>q</u><u>u</u><u>i</u><u>l</u><u>a</u><u>t</u><u>e</u><u>r</u><u>a</u><u>l</u><u> </u><u>t</u><u>r</u><u>i</u><u>a</u><u>n</u><u>g</u><u>l</u><u>e</u> because all sides of the triangle are <u>e</u><u>q</u><u>u</u><u>a</u><u>l</u>.
