Answer:

Amplitude = 1/2

Period  =  \dfrac23 \pi

Phase shift = \pi (left)

Vertical shift = -3

Step-by-step explanation:

f(x)=-\dfrac12cos(3(x+\pi))-3

y = A sin(B(x + C)) + D

Amplitude is A = 1/2

Period  is \dfrac2B \pi =  \dfrac23 \pi

Phase shift is C= \pi (left)

Vertical shift is D = -3

The form is

\\ \tt\longmapsto f(x)=Asin(B(x+c))+D

where

  • A=Amplitude
  • Period=2π/B
  • Phase shift=c
  • Vertical shift=D

Now compare to our given function

  • Amplitude=-1/3
  • Period=2π/3
  • phase shift=c=π
  • Vertical shift=-3

4x - 36 = 2*(x+7) => 4x - 36 = 2x + 14 => 4x - 2x = 50 => x = 25 => DG = 4*25 - 36 = 64.

A store buys lawnmowers from the manufacturer and marks
alina1380 [7]

Answer:

0.7142857

Step-by-step explanation:

Let wholesale price = x

Retail price = 40% Markup of wholesale price

Retail price = (100 + 40)% of x

Retail price = 140% of x

Retail price = 140/100 * x

Retail price = 1.4x

Hence,

Wholesale price / retail price

x / 1.4x

= 0.7142857

Hence, wholesale price is 0.7142857 of the retailer price

What is the area of the sector with a central angle of 49° and a radius of 11 cm? Use 3.14 for pi and round your final answer to
olga_2 [115]

Answer:

\boxed{\text{51.71 cm}^{2}}

Step-by-step explanation:

If the angle θ is in radians, the formula for the area (A) of a sector of a circle is

A = ½r²θ

If θ is in degrees

A = \dfrac{1}{2}r^{2}\theta \times \dfrac{\pi \text{ rad}}{180^{\circ}}= \pi r^{2}\times\dfrac{\theta }{360}

Data:

θ = 49°

r = 11 cm

Calculation:

\begin{array}{rcl}A& = &3.14\times 11^{2}\times\dfrac{49}{360}\\\\ & = &3.14 \times 121 \times 0.1361\\ & = & \mathbf{51.71}\\\end{array}\\\text{The area of the sector is }\boxed{\textbf{51.71 cm}^{2}}

can anyone help me will mark
Ostrovityanka [42]

Answer:

A) infinitely many solutions

Step-by-step explanation:

2x - y = 8

4x - 2y = 16

simplify the first equation

2x - y = 8

2x = 8 + y

2x - 8 = y

y = 2x - 8

substitute y for 2x - 8 in the second equation

4x - 2y = 16

4x - 2(2x - 8) = 16

4x - 4x + 16 = 16

4x - 4x = 16 - 16

0x = 0

since no matter what x is, 0 = 0, the answer is infinitely many solutions
