Answer:

C. 40.5 cm²

Step-by-step explanation:

Use the formula for the area of a trapezoid:

A = (1/2)(b1 +b2)h

The bases are the parallel sides, 4.5 cm and 9 cm. The height is the perpendicular distance between them, 6 cm. Filling in these numbers, we have ...

A = (1/2)(4.5 +9)(6) = 40.5 . . . cm²

Which equation represents a line that is perpendicular to the line passing through (-4,7) and (1,3)?

diamong [38]

The equation perpendicular to the line passing through the points (-4,7) and (1,3) is $y=\frac{5}{4}x-2$

<h3>Equation perpendicular to a line</h3>

The slope of the given line is calculated as:

$m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{3-7}{1-(-4)} \\\\m=\frac{-4}{5}$

The equation perpendicular to the given line will be of the form

$y-y_1=\frac{-1}{m} (x-x_1)$

Substitute $x_1=-4, y_1=7, and m=\frac{-4}{5}$

$y-7=\frac{5}{4}(x+4)\\\\ y=\frac{5}{4}x+5-7\\\\ y=\frac{5}{4}x-2$

Therefore, the equation perpendicular to the line passing through the points (-4,7) and (1,3) is $y=\frac{5}{4}x-2$

The cost of sending an overnight package from Kansas City to Miami is $23.50 for a package weighing up to but not

Ilia_Sergeevich [38]

Answer:

For every pound that the package weight increases, the price of sending it increases by $3.80

Step-by-step explanation:

Overnight from KC to Miami = $23.50 for anything less than a pound + $3.80 per additional pound.

This means that for every pound that the package weight increases, the price of sending it increases by $3.80.
