Answer:
h = 24 cm
Step-by-step explanation:
The formula for area of a triangle is
A = (1/2)bh where b is the base and h is the height.
We are told that the base is 5 times the height, this translates to
b = 5h, so we can rewrite our formula to
A = (1/2)(5h)(h) or
A = (1/2)5h²
We are given A = 1,440, so plug that in and solve for h...
1,440 = (1/2)5h²
2,880 = 5h² (multiply both sides by 2 to get rid of the fraction)
576 = h² (divide both sides by 5 to get the h value by itself)
24 = h (take the square root of both sides)
Answer:
A: No
B: Yes
C: Yes
D: No
Step-by-step explanation:
A: Navy is obviously the bigger ratio so A is wrong
B: If you multiply both values by 18 you get the 3:1 ratio
C: If you Multiply both values by 5, you get the 3:1 ratio
D: Like A, Navy is always going to be bigger so D is wrong
ANSWER
114.52 meters per second
EXPLANATION
We have that the car covers a distance of 5726 meters in 50 seconds.
To find the speed, we have to use the formula for speed which is:
So, the unit rate of speed of the car is:
That is the unit rate of speed of the car in meters per second.
Answer:
Step-by-step explanation:
we would like to find the inverse of the following function:
to do so substitute y for f(x):
interchange variables:
cancel 9 from both sides:
square both sides:
add 4 in both sides:
divide both sides by 4:
substitute back:
and we're done!
