Answer: 16⅔ yds by 25 yds

Step-by-step explanation:

Let x be the length of 3 fence sections

Let y be the length of 2 fence sections

A = xy

3x + 2y = 100

y = 50 - 1.5x

A = x(50 - 1.5x) = 50x - 1.5x²

dA/dx = 50 - 3x

0 = 50 - 3x

3x = 50

x = 50/3 = 16⅔ yds

y = 50 - 1.5(16⅔) = 25 yds

if you invested $45,000 for 8 months at an interest rate of 2.75 % how much interest would you earn?

Masteriza [31]

Answer:

You'd earn $825 in interest.

Step-by-step explanation:

The appropriate formula for simple interest is i = p·r·t, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years. Because 8 months constitutes 2/3 year, we have:

i = $45,000·(0.0275)(2/3) = $825.

You'd earn $825 in interest.

How many real number solutions are there to the equation 0=-3x^2 + x -4

natta225 [31]

We have that
the equation
y=-3x² + x -4
the real number solutions are the points x intercept of the graph
are the points when y=0

using a graph tool
see the attached figure

the graph has no point of intersection with the x axis
therefore

the answer is
there are zero real numbers solutions

The ordered pairs (1,3), (2,9), (3,27), (4,81), and (5,243) represent a function. What is a rule that represents this function?

weqwewe [10]

The rule is 3^x.

Check: 3^1 = 3; 3^2 = 9; 3^3 = 27 and 3^4 = 81
