AURORKA [14]
Area of Trapezoid = h(b1+b2/2)
 b1 and b2 are the lengths of each base and h is the height.

Area = 16(20+24/2)=352 Square Feet

What is the equation of the line that passes through the point (-2, 0) and has
garik1379 [7]

Answer:

y = 2x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2 , then

y = 2x + c ← is the partial equation

To find c substitute (- 2, 0 ) into the partial equation

0 = - 4 + c ⇒ c = 0 + 4 = 4

y = 2x + 4 ← equation of line

A new computer company earns a profit of $245000 in its first year. The company expects the profits to increase by 15% each year
yulyashka [42]

Answer:

$566,700 to the nearest dollar.

Step-by-step explanation:

This is a geometric series with nth term = a1r^(n-1) where common ratio r

= 1.15 and first term a1 = 245000

So in its 7th year the profit will be 245000^ 1.15^(7-1)

= 566699.8876.
