Answer: I will give you hints but not straight up answers kay?
Step-by-step explanation:
In fact, you have undoubtledly encountered non-integer exponents in the past, though you might not have been aware of it at the time! The simplest non-integer power is the square root. Let us review what we do when we take the square root of a number. In taking a square root of 4 for instance, we ask ourselves what number(s) can by multiplied by themselves once in order to give 4? The answer is: well 2 × 2 gives 4 and so does (-2) × (-2). Thus, +2 or -2 raised to the power of 2 gives 4. So the square root of 4 is equal to ±2 (the notation "±" means "plus or minus"). Thus, if Sqrt is to denote the process of taking the square root we have:
22 = 4
Sqrt(22) = Sqrt(4)
2 = Sqrt (4)
Answer:
12x+19.95=13x+9.95
19.95=x+9.95
10=x
So after 10 classes the cost will be the same
12(10)+19.95=120+19.95= $139.95
13(10)=9.95=130+9.95= $139.95
Answer:
1. 8 + t
2. g/15
3. 5b
4. 32 - x
Step-by-step explanation:
1. the sum of 8 and t
8 + t
2. the quotient of g and 15
g/15
3. the product of 5 and b
5b
4. the difference of 32 and x
32 - x
Answer:
2198 cm²
Step-by-step explanation:
Total surface area of a cylinder = 2πrh + 2πr²
Radius, r = diameter/2
= 20cm/2
= 10 cm
Height, h = 25 cm
Total surface area of a cylinder = 2πrh + 2πr²
= 2*3.14*10*25 + 2*3.14*10²
= 1,570 + 6.28*100
= 1,570 + 628
= 2198 cm²
Total surface area of a cylinder = 2,198 cm²
