Its 216 square feet because 24 x 18 / 2 = 216 (divided by two because its a triangle)
They have walked 0.4 miles because half of 0.8 is 0.4.
Answer:
34
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 1, 6 ], thus
f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162
f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8
average rate of change = = = 34
Answer:
A= 18, B= 12
Step-by-step explanation:
A +B= 30 -----(1)
A :B= 3 :2
From the ratio,
A ----- 3 units
B ----- 2 units
Units shall be represented by the letter u from this point forth.
Substitute into equation (1):
3u +2u ---- 30
5u ----- 30
u ----- 30 ÷5= 6
This means that 1 unit represents 6.
A
= 3(6)
= 18
B
= 2(6)
= 12
Answer:
(-3, -8)
Step-by-step explanation:
-8+2/2= -3
-6 -10/2= -8
(-3, -8)
