Answer:
C
Step-by-step explanation:
The last one is absurd. You can't have a ladder reaching higher than itself. The question is a Pythagorean problem.
Givens
a = 3
b = ?
c = 25 feet
Formula
a^2 + b^2 = c^2
Solution
3^2 + b^2 = 25^2
9 + b^2 = 625 Subtract 9 from both sides.
b^2 = 625 - 9
b^2 = 616 Take the square root of both sides.
b = sqrt(616)
b = 24.8
Answer:
18km/[unit of time]
Step-by-step explanation:
v (speed) = d/t
v = 198/11
v = 18
Answer:
-5/4
Step-by-step explanation:
Slope is rise over run which means that the -5 will apply to your y values and the 4 will apply to your x values. This slope would have a point move down 5 units and to the right 4 units to get the location of the next point when going left to right. Because the slope contains a negative, the slope will be angled downward left to right. The negative only applies to the 5.
Answer:
The slope is 6/9.
Step-by-step explanation:
The equation used to calculate the slope from two points is:
(y2 - y1) ÷ (x2 - x1) =
It <u>doesn't matter</u> which x or y you choose to be first since <u>you'll get the same answer</u>. (For me, it's easier to go with the bigger number as the second x & y, so that's what I did.)
(-1 - -7) ÷ (4 - -5) = <u>6/9</u>
