Answer:
y = 2x
Step-by-step explanation:
The equation that represents a proportional relationship that has a constant of proportionality equal to 2 is y = 2x
That is called a constant
like 2,3,234234, -903
it doesn't have a placeholder
Answer:
Step-by-step explanation:
sin θ=1/4,tan θ>0
so θ lies in first quadrant.
cos θ=√(1-sin²θ)=√(1-(1/4)²)=√(1-1/16)=√(15/16)=√15/4
Answer:
164 cm²
Step-by-step explanation:
Take the 2 shapes and find the areas
Triangle area = (bh)/2
13 × 8 × 0.5 = 52
Rectangle area = 16 × 7 = 112
Add up the areas
112 + 52 = 164
9514 1404 393
Answer:
B. 45π cm^3
Step-by-step explanation:
The volume is given by ...
V = 1/3πr^2h
where r is the radius (half the diameter) and h is the height. With the given numbers, we have ...
V = (1/3)π(3 cm)^2(15 cm)
V = 45π cm^3 . . . volume of each cup
