Answer:
There are two ways to find the area of this triangle. One way is to do 19.4 * h / 2 and the other way is to do 17 * 9.4 / 2. Since these are equal we can write:
(19.4h) / 2 = (17 * 9.4) / 2
19.4h = 17 * 9.4 (Multiply the equation by 2 to get rid of the denominators)
h = 17 * 9.4 / 19.4 (Divide by 19.4)
h ≈ 8.2 (Simplify)
Answer:
KE=4000J
Step-by-step explanation:
KE=1/2*mv²
KE=1/2×500×16²
KE=250×16²
KE=4000J

Phantasy [73]
Answer:
A
Step-by-step explanation:
The x values have to be different in order for points not to be on the same vertical line. A function needs to pass the vertical line test.
Answer:
y = 75x - 747
Step-by-step explanation:
formula is y = mx + b
m is slope
slope = change in y / change in x = (-597 - -672) / (2 - 1) = 75 / 1 = 75
m = 75
Now, to find b, substitute any value from the table. Let's do (1, -672)
y = 75x + b
-672 = 75(1) + b
-747 = b
So equation is y = 75x - 747
Use BIDMAS/BODMAS so 9/3=3
15+3= 18
Answer is 18
