Wewaii [24]

Answer:

Step-by-step explanation:

Converting percent to decimal : 2.2/100 = 0.022

Finding 2.2$ of $75k : 75,000 x 0.022 = $1,650 (also the increase in one year)

Finding how much it was worth after 11 years :

(75,000 x 0.022) x 11 = $18,150 or 1,650 x 11 = $18,150

Now add the product to the regular amount to find out the answer:

75,000 + 18,150 = $93,150 (which is how much it increased after 11 years)

A city planner wants to build a road perpendicular to D Street. What is the slope of the new road?

Romashka-Z-Leto [24]

Answer:

The slope of the new road is 0.

Step-by-step explanation:

the slope of d street line is tan(90)

[if the angle made by a line with x axis is $\alpha$ then, the slope of that line will be tan( $\alpha$ ) ]

here, the angle made by the d street line with x axis is 90 degrees.

if a road is to be built which is perpendicular to d street , it should make 0 degrees i.e, it should be parallel to x axis .

so, the slope of new road will be tan(0) = 0
