what is the area of the shaded sector of the circle if the radius is 14 ft? leave your answer in terms of pi

Strike441 [17]

Given:

Radius = 14 ft

θ = 45°

To find:

Area of the shaded sector

Solution:

Area of the sector formula:

$$\text { area of sector }=\frac{\theta}{360^{\circ}} \times \pi r^{2}$

$$=\frac{45^\circ}{360^{\circ}} \times \pi \times 14^{2}$

$$=\frac{1}{8} \times \pi \times 196$

$=24.5\pi$ ft²

The area of the shaded sector of a circle is 24.5π ft².

What is the slope of the line that contains the points (-2,2) and (3,4)

malfutka [58]

<u><em>Answer: B. 2/5 *The answer must have a fraction.</em></u>

Explanation:

Slope-intercept form: → $y=mx+b$

m: represents the slope and is constant.

b: represents the y-intercept.

Used rise/run.

$\frac{rise}{run}$

$x^1,y^1=(-2,2)$

$x^2,y^2=(3,4)$

You had to find the slope by using formula.

$Slope=\frac{y^2-y^1}{x^2-x^1}$

$\frac{4-2}{3-(-2)}$

subtract by the numbers and add the numbers too.

$\frac{4-2=2}{3-(-2)=3+2=5}$

$=\frac{2}{5}$

Hope this helps!

A rectangular box is to have a square base and a volume of 40 ft3. If the material for the base costs $0.36/ft2, the material fo

blagie [28]

Answer:

length: 2 ft
width: 2 ft
height: 10 ft

Step-by-step explanation:

The total cost of the top and bottom is $0.36 + 0.14 = $0.50 per square foot.

The total cost of a pair of opposite sides is $0.05 +0.05 = $0.10 per square foot.

A minimum-cost box will have the cost of any pair of opposite sides be the same. Here, that means the box will have a side area that is 5 times the area of the top or bottom.

Since the base is square, that means the box is the shape of 5 cubes stacked one on the other. Each of those would be 8 ft³, so would have edge dimensions of ∛8 = 2 feet. The height is 5 times that, or 10 ft.

The box is 2 feet square by 10 feet high:

length: 2 ft
width: 2 ft
height: 10 ft

_____

If you feel the need to write an equation, you can let x represent the edge length of the base. Then the cost of the top and bottom will be ...

top&bottom cost = 0.50·x²

The height of the box is 40/x², so the cost of the four sides will be ...

side cost = (0.05)(4x)(40/x²) = 8/x

This is minimized when the derivative of the sum of these costs is zero:

cost = top&bottom cost + side cost

cost = 0.50x² + 8/x

d(cost)/dx = 1.00x -8/x² = 0

Multiplying by x², we get ...

x³ -8 = 0

x = ∛8 = 2 . . . . . . as above

height = 40/x² = 40/4 = 10 . . . . . as above
