You're right the towo numbers are 1.5 and 3.5 so the answer would be 10
Answer:
p(x) = f(x) - g(x) = -0.04x² + 20.96x - 71
Explanation:
The sales are given by f(x) = 24.96x and the cost are represented by g(x) = 0.04x² + 4x + 71.
Then, the profit is equal to
p(x) = f(x) - g(x)
p(x) = 24.96x - (0.04x² + 4x + 71)
p(x) = 24.96x - 0.04x² - 4x - 71
p(x) = -0.04x² + 20.96x - 71
Therefore, the answer is
p(x) = f(x) - g(x) = -0.04x² + 20.96x - 71
Answer:
9 Model As.
Step-by-step explanation:
Let A represent Press A and let B represent Press B.
So, they own 14 total presses. This means that:

They can print 905 books per day, in other words, since A prints 70 per day and B prints 55 per day:

This is now a system of equations. Solve by substitution. From the first equation, subtract B from both sides:

Substitute this into the second equation: "

First, we can divide everything by 5 to simplify things:

Distribute the left:

Combine like terms:

Subtract 196 from both sides:

Divide both sides by -3

So, the company has 5 Model B presses.
Which means that the company has 14-5 or 9 Model A presses.
And we're done!
Answer:
42
Step-by-step explanation:
168 factors into
2•2•2•3•7
two of the 2's make a perfect square
(2•2)•2•3•7
2²•2•3•7
as none of the product of the remaining factors makes a perfect square
2•3 = 6, 2•7 = 14, 3•7 = 21
we need to multiply the remaining factors together to find another perfect square
2²•(2•3•7)²
2•3•7 = 42
42(168) = 7056 = 84²
Answer:
D
Step-by-step explanation:
The formula we need to solve this is:

Where
is the distance from one focus to the vertex
is the second distance from another focus to same vertex
<u>Note:</u> Here, vertex point is the point on top. The common point from which the RED and BLUE line meets the 2 foci
is half the length of the major axis (which is 9 here since total major axis is given as 18)
<em>Now we can plug into the equation and solve:</em>
<em>
</em>
<em />
<em>D is the correct answer.</em>
