Answer:
f(x) = 1/2x + 6
Step-by-step explanation:
So before we even look at the first given formula, let's use the second formula: f(x) = -5.
Plug this formula into the x:
0 <= -5 <= 7
Is this true? Is -5 greater than or equal to 0 and less than or equal to 7?
No, this is false.
So the formula, f(x) = -5, is not the graph of f.
That only leaves one possible option!
Answer:
107.5
Step-by-step explanation:
make d the subject by multiplying both sides by t,d=St . convert 43m to kilometers to get speed in km/hr then multiply it by time (2.5)=0.1075.convert into metres
Answer:
The answer is 90 square units.
Step-by-step explanation:
Volume = the length (3) x height (6) x width (5)
3 x 5 x 6 = 90
The formula for the area of a triangle of base b and altitude h is A = (1/2)(b)(h).
Here, b = 18 cm and h = 9 cm. Thus, the desired area is:
(18 cm)(9 cm)
A = ----------------------- = 81 cm^2
2
This problem gives you more info than is needed to solve it. The area of the given triangle is 81 cm^2.
