The end of a house has the shape of a square surmounted by an equilateral triangle. If the length of the base is measured to be

sergij07 [2.7K]

Answer:

The area of the end is 1755.44 ft²

Therefore, the maximum error in calculating area of the end is 8.3592

Step-by-step explanation:

Consider the provided information.

The length of the base is measured to be 35 feet, with a maximum error in measurement of 1 inch,

$1\ inch = \frac{1}{12}\ feet$

The area of shape = Area of square + Area of equilateral triangle

$A=x^2+\frac{\sqrt{3}}{4}x^2$

Substitute x=35 in above.

$A=(35)^2+\frac{\sqrt{3}}{2}\times (35)^2=1755.44$

Hence, the area of the end is 1755.44 ft²

Differentiate $A=x^2(1+\frac{\sqrt{3}}{4})$ with respect to x as shown:

$dA=2x\ dx(1+\frac{\sqrt{3}}{4})$

Substitute dx =1/12 and x=35

$dA=2(35)\ \frac{1}{12}(1+\frac{\sqrt{3}}{4})=8.3592$

Therefore, the maximum error in calculating area of the end is 8.3592

Which of the following is an example of direct variation?

Dafna11 [192]

Answer: Choice A) y = cx

The 'c' is the constant of variation

For example, if c = 2, then y = 2x is a direct variation. Whatever x is, we double it to get y. As x increases, so does y. As x decreases, then so does y. Both x and y increase/decrease together.

Direct variation equations always go through the origin, and they are always linear. The 'c' plays the role of the slope. You can think of y = cx as y = mx+b where b = 0 in this case and c = m.

Mr. Norel has to work for a minimum of 44 hours per week before he is entitled to any overtime pay

Montano1993 [528]

Answer:

$5832

Step-by-step explanation:

To determine if Mr. Norel is entitled to overtime pay for the month,

$\frac{288}{4}$ = 72 hours

Thus, Mr. Norel is entitled to overtime pay because he worked 72 hours per week.

His total regular pay = $9 x 288

= $2592

His overtime pay = 1.25 x $2592

= $3240

Total pay = regular pay + overtime pay

= $2592 + $3240

= $5832

Therefore, Mr. Norel's earning for the month is $5832.
