mary robertson sells tires at a large car service center. She earns 10% commission on the first $1000.15 percent on the next $20
Illusion [34]

Answer:

$1530 = 45% commission

Step-by-step explanation:

First, jot down the important facts:

• first $1000 = 10% comm.

• next $2000 = 15% comm.

• total more than $3000 = 20% comm.

• total comm. = $3400

Then, go in order with your jotted facts to withdraw the total commission amount. Here's what I mean:

 $3400   ← total is more than $3000 = +20% comm.

<u>- $1000</u>   ← the first $1000 = +10% comm.

 $2400

<u>- $2000</u>   ← the next $2000 = +15% comm.

   $400

Then, add together the commission percentages:

20% + 10% + 15% = 45% comm.

Convert the percentage to a decimal:

45% × 100 = 0.45

And multiply it with the total amount to find the commission amount:

$3400 × 0.45 = $1530

In △PKQ, PK = KQ = 12, m∠P = 35º. Find PQ.
Neporo4naja [7]

The length of PQ is 19.66 units

Step-by-step explanation:

The given is:

1. PK = KQ = 12

2. m∠P = 35º

We need to find the length pf PQ

∵ PK = KQ

∴ m∠P = m∠Q

∵ m∠P = 35°

∴ m∠Q = 35°

The sum of measures of the angles of a triangle is 180°

∴ m∠P + m∠Q + m∠K = 180°

∴ 35 + 35 + m∠K = 180

∴ 70 + m∠K = 180

- Subtract 70 from both sides

∴ m∠K = 110°

Let us use cosine rule to find the length of PQ

∵ PQ = \sqrt{(KP)^{2}+(KQ)^{2}-2(KP)(KQ)cos(K)}

∵ PK = 12 , KQ = 12 , m∠K = 110°

- Substitute these values in the rule

∴ PQ = \sqrt{(12)^{2}+(12)^{2}-2(12)(12)cos(110)}

∴ PQ = 19.66

The length of PQ is 19.66 units

\text{We have been given the function }\\&#10;f(x)=(x-1)^2-4\\&#10;\text{Let f(x)=y}\\&#10;y=(x-1)^2-4\\&#10;\text{Swap x and y, we get}\\&#10;\\&#10;x=(y-1)^2-4\\&#10;\text{Now we solve for y}\\&#10;(y-1)^2=x+4\\&#10;\\&#10;y-1=\pm \sqrt{x+4}\\&#10;\\&#10;y=1\pm \sqrt{x+4}\\&#10;\\&#10;f^{-1}(x)=1\pm \sqrt{x+4}\\

x+4\geq 0\\&#10;x\geq -4\\&#10;\text{Thus, the domain is given by}\\&#10;x\in [-4,\infty )
