Answer: (5,-6)
Step-by-step explanation:
Answer:
3. 1.5ft x 3.14 = 4.71ft.
6. 2 yd. since that is the radius, you multiply by 2 for the diameter.
4 yds. x 3.14 = 12.56 yds.
9. 2.5m x 3.14 = 7.85m
Step-by-step explanation:
You multiply the diameter with pi(3.14) and you get the circumference.
Cancel one variable to solve for one. Multiply the two equation by 4 and 3
12x+12=-24
12x-12y=-72
Then the y variables cancel different sings
24x=-96
Tren divide and you get -4
Answer:
See below.
Step-by-step explanation:
The density = mass / volume
= 612 / 245
= 2.50 g/cm^3.
The literature states a density of 2.70 for the density of aluminium. The only other metal which is close to this value is strontium ( d = 2.64) which is a silvery colour so it might be that. One way to find out which it i s to see if the metal reacts with water. Aluminium does not while strontium does.
Answer:
The value of f(1) is larger than the value of f(3)
Step-by-step explanation:
Put the numbers in the equation and do the arithmetic.
f(1) = -2(1²) +3(1) +10 = 11
f(3) = -2(3²) +3(3) +10 = 1
11 is larger than 1, so f(1) is larger than f(3).
