Solve for x

Mathematics

Answer:

B

Step-by-step explanation:

We have 2 inequalities, so we will obtain at maximum 2 ranges for x

5x-29>-34. Lets solve for x, pass -29 to the other side

5x>-34+29, this gives 5x>-5, from that we obtain the first range x>-1

(-1, inf)

The second one is similar

2x+31<29, solving for x you have the following: 2x>-2 <(note that we have to reverse the < sign since the "-" sign that appears when performing the subtraction -31+29=-2) thus you have x>-1, our second range is (-1, inf)

Comparing the two ranges... we have x>-1 repeating, thus, is enough to say that we have only one range, x>-1

So, using the number 3,200,000 deaths per year, you want to divide it until it reaches deaths per minute.
3,200,000 divided by 365 (for days)
8767.123 divided by 24 (for hours)
365.297 divided by 60 (for minutes)
and so you get 
6.088 deaths per minute

Hope this helped.

A home gardener estimates that 24 apple trees will have an average yield of 104 apples per tree. But because of the size of the
d1i1m1o1n [39]

Answer:

The farmer should plant 14 additional trees, for maximum yield.

Step-by-step explanation:

Given

Trees = 24

Yield = 104

x \to additional\ trees

So, we have:

Trees = 24 + x

Yield = 104 - 2x

Required

The additional trees to be planted for maximum yield

The function is:

f(x) = Trees * Yield

f(x) = (24 + x) * (104 - 2x)

Open bracket

f(x) = 24 * 104 + 104x - 24 * 2x - x * 2x

f(x) = 2796 + 104x - 48x - 2x^2

f(x) = 2796 + 56x - 2x^2

Rewrite as:

f(x) = - 2x^2 + 56x + 2796

Differentiate

f'(x) = -4x + 56

Equate f'(x) = -4x + 56 to 0 and solve for x to get the maximum of x

-4x + 56 = 0

-4x =- 56

Divide by -4

x =14

The farmer should plant 14 additional trees, for maximum yield.
