What is the slope of a line that passes through the points (12,7) and (-14,19)?

grandymaker [24]

Answer:

H) -6/13

Step-by-step explanation:

To find the slope of the line between a pair of two points, use the slope formula, $m = \frac{y_2-y_1}{x_2-x_1}$ . Substitute the x and y values of (12,7) and (-14,19) into the formula and simplify like so:

$m = \frac{(19)-(7)}{(-14)-(12)} \\m =\frac{19-7}{-14-12} \\m = \frac{12}{-26} \\m = -\frac{6}{13}$

So, Option H is correct.

New streetlights will be installed along a section of the highway. The posts for the streetlights will be 7.5 m tall and made of

SIZIF [17.4K]

First, we determine the volumes of the posts may it be cylindrical in shape or rectangular prism.

(A) cylindrical:
( π(26.7/100)² - π(24.2/100)²)*(7.5) = 0.3 m³
(B) rectangular prism:
(40/100)²(7.5) - (35/100)²(7.5) = 0.28125 m³

Then, we calculate for the amount of substance
(A) cylindrical: (0.3 m³)(2700 kg/m³) = 810 kg
(B) rectangular prism : (0.28125 m³)(2700 kg/m³) = 759.375 kg

Then, calculate for the costs
(A) (810 kg)($0.38/kg) = $307.8
(B) (759.375 kg)($0.38/kg) = $288.56

Thus, the answer for A is rectangular post
B. About $19.24 can be saved.

The density d of a substance is given by the formula d=mV, where m is its mass and V is its volume. Solve the formula for m.

NikAS [45]

Answer:m=d/V

Step-by-step explanation:

To solve for m, you must divide V from each side. Leaving you with m=d/V. Hope this helped:)
