The first two are equivalent to 15 = k + 13

8 = k + 13 - 7 → ( add 7 to both sides )

8 + 7 = k + 13 ⇒ 15 = k + 13 ' is equivalent '

12 = k + 13 - 3 → ( add 3 to both sides )

12 + 3 = k + 13 ' is equivalent '

Answer:

Step-by-step explanation:

The formula for simple interest is

I = Prt,

where I is the interest earned,

r is the interest rate in decimal form, and

t is the time in years.  For us,

I = 75,

P = ?

r = .05

t = 1

75 = P(.05)(1) and

.05P = 75 so

P = 1500

State the horizontal asymptote of the rational function. For full credit, explain the reasoning you used to find the horizontal
Rzqust [24]

So here are the rules of horizontal asymptotes:

  • Degree of Numerator > Degree of Denominator: No horizontal asymptote
  • Degree of Numerator = Degree of Denominator: y=\frac{\textsf{leading coefficient of numerator}}{\textsf{leading coefficient of denominator}}
  • Degree of Numerator < Degree of Denominator: y = 0

Looking at the rational function, since the degree of the numerator is 2 and the degree of the denominator is 1 (and 2 > 1), this means that <u>this function has no horizontal asymptote.</u>

Emily makes cylindrical bars of soap to sell online. Each bar has a radius of 3.5 cm and a length of 4 cm. Each bar is wrapped i
Mariulka [41]

Answer:

C) 1050π cm²

Step-by-step explanation:

Surface area of a cylinder = 2πrh + 2πr²

radius, r = 3.5cm

Height, h = 4 cm

Surface area of a cylinder = 2πrh + 2πr²

= 2 * π * 3.5 * 4 + 2 * π * 3.5²

= 28π + 2π * 12.25

= 28π + 24.5π

= 52.5π cm²

Surface area of a cylinder = 52.5π cm

There are 20 bars of soap

Total plastic Emily needs for 20 bars of soap = surface area of each soap × 20

= 52.5π cm² × 20

= 1,050π cm²
