The coordinates of the vertices of the triangle are
(–8, 8), (–8, –4), and<span> (10, –4)</span>.
Consider QR the base of the triangle. The measure of the base is b = 18 units, and the measure of the height is h = <span>12</span> units.
The area of triangle PQR is<span>108</span> square units.
Answer:
4, 2, 1, 2, 4
Step-by-step explanation:
-2 <= 0, so use the first equation, f(x) = (1/2)^x, to find f(-2).
f(-2) = (1/2)^-2 = 1^-2/2^-2 = 2^2/1^2 = 4/1 = 4
-1 <= 0, so use the first equation, f(x) = (1/2)^x, to find f(-1).
f(-1) = (1/2)^-1 = 1^-1/2^-1 = 2^1/1^1 = 2/1 = 2
0 <= 0, so use the first equation, f(x) = (1/2)^x, to find f(0).
f(0) = (1/2)^0 = 1^0/2^0 = 1/1 = 1
1 > 0, so use the second equation, f(x) = 2^x, to find f(1).
f(1) = 2^1 = 2
2 > 0, so use the second equation, f(x) = 2^x, to find f(2).
f(2) = 2^2 = 4
Answer:
$3.20
Step-by-step explanation:
I divided the $2 by 8 to see how much 1/8 a gallon cost.
I got 0.40
Multiple this by 8 to get 8/8 or 1 gallon.
You get 3.2
so $3.20
Hope this helped. :)
Answer:
12.5 hours
Step-by-step explanation:
The function d(x) = 1375 -110x represents the distance in miles a high-speed train is from its destination after x hours of travel.
So, when the train reaches its destination then d(x) will become zero miles.
Therefore, 0 = 1375 - 110x
⇒ x = 12.5 hours.
So, the train will travel 12.5 hours to reach its destination. ( Answer )
