McKenzie delivers coupons to her neighborhood. This week she has 553 coupons to deliver. If she wants to give 7 coupons to each neighbor, which equation can be used to find the number of neighbors, n, to whom McKenzie can give coupons?

Answers

Answer:

Number of neighbors to whom McKenzie can give coupons = 79

Step-by-step explanation:

Coupons to deliver this week = 553

Coupons delivered to each neighbor = 7

which equation can be used to find the number of neighbors, n, to whom McKenzie can give coupons?

Let

n = number of neighbors to whom McKenzie can give coupons

n = Coupons to deliver this week / Coupons delivered to each neighbor

= 553 / 7

= 79

n = 79 neighbors

Number of neighbors to whom McKenzie can give coupons = 79

Find the area of the parallelogram.

Answers

Answer:

36 ft^2

Step-by-step explanation:

I) Find dimensions:

The base is 9 feet, and the height is 4 feet.

(Remember, 6 ft is not the height because that is the height of the parallelogram's parallel sides.)

II) Find area:

Area = base x height

A = B x H

36 = 9 x 4

III) Find unit:

Make sure to add the unit, it is ft^2 or ft² since this figure is three-dimensional and measured in feet.

The line l is tangent to the circle with equation x2 + y2 = 17 at the point P.
Determine the equation of line l.

Answers

The line is perpendicular to the line from origin to P (by tangent is perpendicular to radii)
Which slope is 1/4
So the
(slope of tangent) x (1/4) = -1

Slope of tangent = -4
Point slope form:
(y-1)/(x-4)=-4
y-1=-4x+16
y=-4x+17

Or you can construct the upper half of the circle in y=(17-x^2)^(1/2) and differentiate it to get the slope then use point slope form again
