Suppose a baby food company has determined that its total revenue R for its food is given by R = − x 3 + 39 x 2 + 945 x where R

Paraphin [41]

Answer:

35,000 units

Step-by-step explanation:

Total revenue is:

$R = -x^3+39x^2+945x$

The maximum revenue is attained at the production level for which the derivate of the revenue function is zero:

$R = -x^3+39x^2+945x\\R'=0=-3x^2+78x+945\\x=\frac{-b\pm\sqrt{78^2-(4*(-3)*945)} }{-6}\\x_1=35\\x_2=-9$

Since production cannot be negative, revenue will be at a maximum when x = 35, or when the production level is 35,000 units.

Seven - tenths of the votes for blue were made by girls. Did girls who voted for blue make up more than or less than half of all

Ludmilka [50]

Answer:

More than half

Step-by-step explanation:

10/10 would be one whole, and half of ten is 5, which makes 5/10 equal to one half. 7 is greater than 5, so that means 7/10 is more than one half. Hope this helps!

Glenda and Penny are doing

Volgvan

Answer:

It depends on how many inches they are from the finish line.

Step-by-step explanation:

However, they will be at the same distance at 90 inches when Glenda hops 5 times. 18 x 5 = 90. Penny will also make it to 90 inches when she hops 6 times. 15 x 6 = 90. Then, you will subtract 90 inches from how long the race is in inches.

Hope this helps!

The height of a wooden pole, h, is equal to 20 feet. A taut wire is stretched from a point on the ground to the top of the pole.

kykrilka [37]

ANSWER

D. 25 feet

EXPLANATION

The height of the wall,h, the taut wire and the distance from the base of the pole to the point on the ground, formed a right triangle.

According to the Pythagoras Theorem, the sum of the length of the squares of the two shorter legs equals the square of the hypotenuse.

Let the hypotenuse ( the length of the ) taught wire be,l.

Then
