1 answer:

5 0

Step-by-step explanation:

The length along the x-axis is 5 - (-1) = 6. The length along the y-axis is 3 - (-1) = 4. The perimeter of this rectangle can be calculated as

$P = 2x + 2y = 2(6) + 2(4) = 20\:\text{units}$

The area of the rectangle can be calculated as

$A = xy = (6)(4) = 24\:\text{units}^2$

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.

Cot(90° − x) = 1 The value of x that satisfies this equation is Blank °.

Reil [10]

Answer:

$x=90\degree$

Step-by-step explanation:

The given trigonometric equation is

$\cos(90\degree -x)=1$

We take the inverse cosine of both sides to obtain;

$(90\degree -x)=\cos^{-1}(1)$

$(90\degree -x)=0$

Group similar terms t obtain;

$-x=0-90\degree$

$x=90\degree$
