Answer: If there is no real solution, enter NO REAL SOLUTION.)  Find all solutions of the equation and express them in the form  x^3 − 2x^2 − 7x + 14 = 0. -separate the problem into factoring: x^3 and 2x^2 will be the outside numbers √(x + 42)=x ... Use f(x) = 4x − 3 and g(x) = 5 − x^2 to evaluate the expression. (f o g) (-2)

The probability you get tails and select a white golf​ ball is 0.36

Step-by-step explanation:

There are 2 yellow golf balls: Y1 and Y2

There are 5 white golf balls: W1, W2, W3, W4 and W5

Then, the sample space is: ​{HY1, HY2,​ HW1, HW2,​ HW3, HW4,​ HW5, TY1,​ TY2, TW1,​ TW2, TW3,​ TW4, TW5}

What is the probability you get tails and select a white golf​ ball?

desired outcomes {TW1,​ TW2, TW3,​ TW4, TW5}

number of desired outcomes: 5

number of possible outcomes: 14

I need help with this math problem
mr Goodwill [35]

Let X = number of minutes.

Plan A = 50 + 0.04X

Plan B = 60 + 0.02X


50 + 0.04X = 60 + 0.02X

Subtract 50 from each side:

0.04X = 10 + 0.02X

Subtract 0.02X from each side:

0.02X = 10

Divide both sides by 0.02

X = 10 / 0.02

X = 500

It will take 500 minutes.

A physician orders 140mg of a medication to give orally. You have 125mg/5mL on hand. What is the correct dose of medication to g
adelina 88 [10]
<h2>Hello!</h2>

The answer is: The correct dose of medication to give is 5.6 mL

<h2>Why?</h2>

To solve this problem we need to establish a relationship between the prescripted medication and the available solution.

Let's write the needed equations to establish the relantionship:

\frac{125mg}{5mL}=1\\\\125mg=5mL

The available solution means 125 mg each 5 mL of solution, so:

\frac{125mg}{5mL}=\frac{140mg}{x}\\\\x*\frac{125mg}{5mL}=140mg\\\\x=140mg*\frac{5ml}{125mg}=\frac{700mg*mL}{125mg}=5.6mL

Hence, the correct dose of medication to give is 5.6 mL of the 125 mg/5mL solution.

Have a nice day!
