Taylor charges $15 for the first hour of dog walking and $10 for each additional hour or fraction of an hour. The rates that Luc

svetoff [14.1K]

Answer:

Taylor will charge more by $15

Step-by-step explanation:

Given

Taylor

First Hour = $15

Hourly Rate = $10

Lucy:

$f(x) = \left \{ {{20x,\ 0 \le \ x \ \le 2} \atop {10x, x>2}} \right.$

For a dog walk of 2.5 hours.

Taylor's charges is:

$Charges = First\ Hour + Hourly\ Rate * 2.5$

$Charges = \$15 + \$10 * 2.5$

$Charges = \$15 + \$25$

$Charges = \$40$

Lucy's charges is:

Here, we consider

$f(x) = 10x$ Because $x > 2$

i.e 2.5 > 2

So, Lucy's charges is:

$Charges = 10 * \$2.5$

$Charges = \$25$

By comparison;

Taylor will charge more by $15

The difference is calculated by:

$Difference = \$40 - \$25$

$Difference = \$15$

What is the approximate radius of a sphere with a volume of 34 cm3?

xz_007 [3.2K]

Answer:

Step-by-step explanation:

The formula of a volume of a sphere:

$V=\dfrac{4}{3}\pi R^3$

R - radius

We have

$V=34\ cm^3$

Substitute:

$\dfrac{4}{3}\pi R^3=34$ multiply both sides by 3

$3\!\!\!\!\diagup^1\cdot\dfrac{4}{3\!\!\!\!\diagup_1}\pi R^3=(3)(34)$

$4\pi R^3=102$ divide both sides by 4

$\dfrac{4\pi R^3}{4}=\dfrac{102}{4}$

$\pi R^3=\dfrac{51}{2}$ divide both sides by π

$\dfrac{\pi R^3}{\pi}=\dfrac{\frac{51}{2}}{\pi}$

$R^3=\dfrac{51}{2\pi}$ use π ≈ 3.14

$\R^3\approx\dfrac{51}{(2)(3.14)}$

$R^3\approx\dfrac{51}{6.28}\\\\R^3\approx8.121\to R\approx\sqrt[3]{8.121}\\\\R\approx2.01\ cm$

3x 2 + 7x - 5 name the terms

Ulleksa [173]

Answer:

Hello! Your answer would be, BELOW

Step-by-step explanation:

$-3x^{2} - 7x - 5$

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

Term's are 7x and 5
