Answer:

a)-2,0,6 b) ,A,B,C

Step-by-step explanation:

  • solve the x and y axis by using graphical method
  • because we have been given the values of x we replace them by the values given hence we can say y=-2²+2 which is -2 for the first box in ad then 0in the second and 6 in the third
  • you come and look in the graph which suits the equation by using the table you completed like -1on the x axis and 1 on the y axis goes for both Curve A and B then 2 on the x axis and 6 on the y axis goes for curveC

<u>Answer:</u>

Vt = 4071.5 ft^3

<u>Step-by-step explanation:</u>

Givens:

  • R = 12
  • R = 2r => r = 6

Equations

  1. V = (4/3)(pi)r^3

Find: Vt (Total Volume)

Vt = (1/2)V1 + (1/2)(V2)

Vt = (1/2)(V1 + V2)                 <em>[Factor out (4/3) and (pi) from volumes]</em>

Vt = (1/2)(4/3)(pi)(R^3 + r^3)  <em>[Sub in Values]</em>

Vt = 4071.5 ft^3

6. (07.02 MC)
Alexus [3.1K]

Answer:

x = 28.07°

Step-by-step explanation:

Recall: SOH CAH TOA

Reference angle given = x°

Opposite = 8

Hypotenuse = 17

Apply SOH:

Sin x = \frac{Opp}{Hyp}

Substitute

Sin x = \frac{8}{17}

x = sin^{-1}(\frac{8}{17})

x = 28.07° (nearest hundredth)

The solution for the system equations 8x-6y=-32 and -8x+5y=36
Ghella [55]

Answer:

x=47, y=68

Step-by-step explanation:

Add the two equations. Then we get

-y=-68

y=68

Substituting the value of y in the first equation,

8x-6(68)=-32

8x-408=-32

8x=376

x=47
