A parallelogram has sides of length 16 units and 10 units. The shorter diagonal is 11 units. Find the measure of the longer diag
lord [1]

The measure of the longer diagonal is 24.31 units

<h3>How to determine the longer diagonal?</h3>

The side lengths are given as;

a = 16

b = 10

The shorter diagonal is represented as d1, and it is given as

d1 = 11

The longer diagonal is represented as d2, and it is calculated using

d1^2 + d2^2 = 2 * (a^2 + b^2)

Substitute the known values in the above equation

11^2 + d2^2 = 2 * (16^2 + 10^2)

Evaluate the sum

121 + d2^2 =2 * 356

Evaluate the product

121 + d2^2 = 712

Subtract 121 from both sides

d2^2 = 591

Take the square root of both sides

d2 = 24.31

Hence, the measure of the longer diagonal is 24.31 units

The Wal-Mart buys sweatshirts for $38 each andsells them at a 60% increase in price. What is the amount of increase? What is the
Luba_88 [7]
To find the amount increase in price, you will calculate what 60% of the $38 is by multiplying 0.6 and 38

0.6 x 38 = $22.80 is the amount of increase.

The retail price is found by adding the increase to the cost.

$38 + $22.80 =   $60.80.

How do I find the exact area of a circle with a diameter
kirill115 [55]

Answer:

Divide the diameter by 2 and insert for radius in the equation

Step-by-step explanation:

To find the area of a circle, we can use the equation <em>A=pir^2 </em>or <em>area=pi*radius squared.</em>

The radius is half of the diameter, so just divide the diameter by 2 and plug it into the equation.

Hope this helps!

A company has determined that when x hundred dulcimers are​ built, the average cost per dulcimer can be estimated by ​C(x)=0.2x^
damaskus [11]

Answer:

The minimum average cost per dulcimer is 150 and the minimum cost is $180.

Step-by-step explanation:

The given cost function is

C(x)=0.2x^2-0.6x+2.250

Differentiate the function C(x) with respect to x.

C'(x)=0.2(2x)-0.6(1)+(0)

C'(x)=0.4x-0.6

Equate C'(x)=0, to find the critical values.

C'(x)=0

0.4x-0.6=0

0.4x=0.6

Divide both sides by 0.4.

x=\frac{0.6}{0.4}

x=1.5

Differentiate the function C'(x) with respect to x.

C''(x)=0.4(1)

C''(x)=0.4

At x=1.5

C''(1.5)=0.4

The value of double derivative is positive. It means the function is minimum  at x=1.5 hundred.

1.5 hundred = 150

Substitute x=1.5 in the given function to find the minimum average cost.

C(1.5)=0.2(1.5)^2-0.6(1.5)+2.250

C(1.5)=1.8

The minimum cost is 1.8 hundred dollars.

1.8 hundred dollars = $180

Therefore, the minimum average cost per dulcimer is 150 and the minimum cost is $180.
