does somebody knows how to do this one?
vlada-n [284]

Answer:

Step-by-step explanation:

To find the area subtract the area of the semicircle from the area of the rectangle.

Although the line isn’t there, if you imagine there is one, then you will see that you form a rectangle which is the same line as the semicircle’s diameter.

The area of rectangle is:

⇒ A = lw

⇒ A = (14)(8)

⇒ A = 112cm^{2}

The area of the semicircle;

⇒ A = \frac{1}{2}\pi r^{2}

⇒ A = \frac{1}{2}\pi (7)^{2}

*Note here that the radius is half the diameter, so it is 7cm, not 14cm

⇒ A = 76.97cm^{2}

Finally subtract the two areas;

⇒ A = 112 - 76.97

⇒ A = 35.03cm^{2}

I am so confused! Can anyone help me with this trig problem?
Dominik [7]

\frac{5\pi }{4} or \frac{7\pi }{4}

divide both sides by 2

sinΘ = - \frac{\sqrt{2} }{2}

Since the sin ratio is negative then Θ is in third / fourth quadrants

Θ = sin^{- 1} (\frac{\sqrt{2} }{2}) = \frac{\pi }{4} related acute angle

Θ = ( π + \frac{\pi }{4} ) = \frac{5\pi }{4}

or Θ = ( 2π - \frac{\pi }{4} ) = \frac{7\pi }{4}

The functions f (x) = 1/2x-3 and g(x) = -2x+ 2 intersect<br> at x = -2. True or false?
Norma-Jean [14]

9514 1404 393

Answer:

  False

Step-by-step explanation:

f(-2) = (1/2)(-2) -3 = -1 -3 = -4

g(-2) = -2(-2) +2 = 4 +2 = 6

The function values are not the same at x=-2, so the graphs do not intersect there.

__

The graphs intersect at x=2.

Answer: Team one = 1/5

Team 2 = 4/21

Team A is the fastest

Step-by-step explanation: Answer: Team one = 1/5

Team 2 = 4/21

Team A is the fastest

Step-by-step explanation: TEAM A

Tammy working alone in 1hr can clean 1/2

Melissa working alone in 1 hr  can clean 1/3

working together in 1hr ,let x represent the area they will clean  we have

\frac{1}{1/2} + \frac{1}{1/3} = 1/x

⇒ 3 + 2 = 1/x

5 = 1/x

x = 1/5

TEAM B

Santay working alone can clean  1/4

Leticia working alone in 1 hr can clean 4/5

working together in 1 hr ,let y represent the amount they clean,  we have

\frac{1}{1/4} + \frac{1}{4/5} = 1/y

4 + 5/4 = 1/y

21/4 = 1/y

y = 4 /21

comparing x and y , 1/5 is greater than 4/21 , therefore Team A is faster
