For the function F defined by F(x) = x^2 – 2x + 4, find F(| – 4|).
Morgarella [4.7K]

| - 4 | = 4

Thus :

f ( | - 4 | ) = f ( 4 )

f ( 4 ) = ( 4 )^2 - 2(4) + 4

f ( 4 ) = 16 - 8 + 4

f ( 4 ) = 16 + 4 - 8

f ( 4 ) = 20 - 8

f ( 4 ) = 12

What is the simplified form of 3 Start Root 5 c End Root times Start Root 15 c cubed End root? (worth 30 brainily points)
aleksley [76]

Answer:

A. 15 c squared Start Root 3 End Root

Step-by-step explanation:

3\sqrt{5c} *\sqrt{15c^3} \\

Multiply the terms inside the square roots together

3\sqrt{75c^4}

Look for items that are perfects squares

3\sqrt{25*3*c^4}

We can separate terms inside the square root into separate square roots

3\sqrt{25} *\sqrt{3}*\sqrt{c^4}

3*5 *\sqrt{3} *c^2

Combine like terms

15c^2\sqrt{3}

You buy 4 bags of sand and 3 bags of pea gravel for $24. In a second purchase (at the same prices), you buy 2 bags of sand for $
Kazeer [188]

Answer:

x = $3

y = $4

Step-by-step explanation:

We need to know the prices of gravel and peas. We can find the price by using equations and graphing them.

Let X be the price of the sand

Be and the price of pea gravel

In the first purchase we have:

4x + 3y = 24

In the second purchase we have

2x = 6

Both relations represent the equation of a line. In the graphic shown, these lines are drawn. In this case the interception between both lines represents the price of each product, and the solution of the problem. You can see that the lines intersect at point (3 4). This means that the price of each bag of sand is $ 3, and the price of a bag of pea gravel is $ 4.
