Answer:

36

Step-by-step explanation:

The tangents from the same point are equal. Each point of the triangle extend 2 tangents to the circle.

Tangents from the uppest point: 8+8=16

Tangents from the lowest point: 4+4=8

Tangents from the third point:

10-4=6

6+6=12

Perimeter: 16+8+12=36units

Find the area of the figure.<br><br> answer choices:<br> 31 ft², 80 ft², 40 ft², 60 ft²
IrinaVladis [17]

Answer:

60 ft²

Step-by-step explanation:

You can divide the figure into 2 parts.

First, solve for the rectangle: Area of a rectangle = b*h = 4ft x 10ft = 40ft²

Then, solve for the triangle:

Height = 10ft - 5ft = 5ft

Base = 12ft - 4ft = 8ft

Area of a triangle = (b*h)/2 = (5ft x 8ft)/2 = 20ft²

Just add them together: 20ft² + 40ft² = 60ft²

Please someone help me...​
Savatey [412]

use a^2-b^2=(a+b)(a-b)

to get (\cos^3A-\sin^3A)(\cos^3A+\sin^3A)

then use a^3+b^3=(a+b)(a^2+b^2-ab)

and a^3-b^3=(a-b)(a^2+b^2+ab)

also, \sin^2\theta+\cos^2\theta=1

to get (\cos A-\sin A)(1+\sin A\cos A)(\cos A+ \sin A)(1-\sin A\cos A)

then again use the first identity In both pairs, i.e.

(\cos A-\sin A)(\cos A+ \sin A) \cdot (1+\sin A\cos A)(1-\sin A\cos A)

to get \cos 2A (1-\sin^2A\cos^2A)

multiply and divide by 4 to get the RHS.

because, \sin(2A)= 2\sin A \cos A

squaring both sides, \sin^2 (2A)=4\sin^2A\cos^2A

Which of the following charts can be used to determine the cumulative probability that several sources contribute to a problem?
Svetllana [295]

Answer: a. Pareto

Step-by-step explanation:

A Pareto Chart is a graph that indicates the frequency of defects, as well as their cumulative impact. Pareto Charts are useful to find the defects to prioritize in order to observe the greatest overall improvement.

Fishbone diagram or Ishikawa diagram is a cause-and-effect diagram that helps managers to track down the reasons for imperfections, variations, defects, or failures.

Ordered Histogram is an approximate representation of the distribution of numerical data.

A histogram is a bar graph that illustrates the frequency of an event occurring using the height of the bar as an indicator.

What is the period of y = 8 cos (5pie x + 3pie/2)-9<br> Give an exact value. Units
zzz [600]

\\ \rm\Rrightarrow y=Acos(Bx+C)+D

  • This is the general formula and the period is 2π/B

Now our given function

\\ \rm\Rrightarrow y=8cos\left(5\pi x+\dfrac{3\pi}{2}\right)-9

On comparing we get

  • A=8
  • B=5π
  • C=3π/2
  • D=-9

Period:-

\\ \rm\Rrightarrow \dfrac{2\pi}{B}

\\ \rm\Rrightarrow \dfrac{2\pi}{5\pi}

\\ \rm\Rrightarrow \dfrac{2}{5}
