Answer:

Step-by-step explanation:

Multiply $120 (cost of haircut) X .18 (18% in decimal form) to get the tip amt.

120 X .18 = 21.60

Now add $120 (haircut) + 21.60 (tip) together to get the total amt. she paid.

120 + 21.60 = $131.60

Carla gave her stylist $131.60 total

This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive an

Answer:

5.0 ft-lbf

Step-by-step explanation:

The force is

$F = \dfrac{9}{6^x}$

This force is not a constant force. For a non-constant force, the work done, W, is

$W = \int\limits^{x_2}_{x_1} {F(x)} \, dx$

with $x_1$ and $x_2$ the initial and final displacements respectively.

From the question, $x_1 =0$ and $x_2 = 12$ .

Then

$W = \int\limits^{12}_0 {\dfrac{9}{6^x}} \, dx$

Evaluating the indefinite integral,

$\int\limits \dfrac{9}{6^x} \, dx =9 \int\limits\!\left(\frac{1}{6}\right)^x \, dx$

From the rules of integration,

$\int\limits a^x\, dx = \dfrac{a^x}{\ln a}$

$9 \int\limits \left(\frac{1}{6}\right)^x \, dx = 9\times\dfrac{(1/6)^x}{\ln(1/6)} = -5.0229\left(\dfrac{1}{6}\right)^x$

Returning the limits,

$\left.-5.0229\left(\dfrac{1}{6}\right)^x\right|^{12}_0 = -5.0229(0.1667^{12} - 0.1667^0) = 5.0229 \approx 5.0 \text{ ft-lbf}$

How would you explain the proper use of distributive property ?

Maksim231197 [3]

Start with the word “distribute” meaning to pass equally. Now distributive property means to distribute equally. For example 2(4x+5) you wanna distribute the 2 amount the parentheses so that it’s”distributed evenly. 2(4x+5) is now 8x+10
