Answer:

A = 907.46 m^{2}

Step-by-step explanation:

C = πd

34π = πd

d = 34

r = 17

A = \pi r^{2} = 3.14(17^{2}) = 3.14(289) = 907.46 m^{2}

Given the equation f(x) = 2x² + 4x - 1, what is axis of symmetry? a. 1 c. -1 b. 2 d. 0
Irina-Kira [14]

Answer: x=-1

Step-by-step explanation:

the x value of the vertex = -b/2a if the equation is in "ax^2+bx+c" for

you are in luck

x value of the vertex = -4/4 = -1

the line of symmetry is a vertical line, and since it must pass through the vertex

line of symmetry: x=-1

A pet store contains 35 light green parakeets (14 females and 21 males) and 44 sky blue parakeets (28 females and 16 males). You

You can use this formula <span>P(AorB) = P(A) + P(B) - P(AandB) 

Given:
35 LG (14 F & 21 M)
44 SB (28 F & 16 M)

Req:
- the probability that it is a female (F) or a sky blue (SB)

Sol:
</span>P(F or SB) = P(F) + P(SB) - P(F and SB) 
                 = [(14 F + 28 F)/(35 + 44)] + [(44 SB)/(35 + 44)] - [(28 F)/(35 + 44)]
                 = 53.16 + 55.70 - 35.44
                 = 73.42%

You have to deduct 28 female parakeets from 44 sky blue parakeets because the 28 parakeets are already accounted for in the female parakeets. You can also think of how many ways you can choose a female parakeet and a sky blue parakeet. Add all female parakeets (14 + 28) = 42. Sky blue parakeet equaled to 44. Minus the 28 female parakeets included in the sky blue parakeet to avoid double counting. 42 + 44 - 28 = 58 divided by 79 (35 + 44) total parakeets = 73.42%

Find the volume of each figure
konstantin123 [22]

Answer:

<u>1) 17.5×14×64</u>

  • → 1568 in³

<u>2) volume= 0.5×3.6×10×5=</u>

  • → 90

<u>3) d= 13, r=13/2= 6.5, h= 19</u>

  • → v= πr²h
  • → π(6.5)²×19
  • → 2521.91 mm³

<u>4) Base Area= a+b/2×h</u>

  • → (37+15)/2×25.7 cm²
  • →26×25.7 cm²
  • → 668.2 cm²
  • height= 20cm
  • voulme = 668.2×20
  • → 13364 cm²

<u>5) L×W×H</u>

  • → 25×7×18
  • → 175×18
  • → 3150 ft³

<u>6) v=πr²h</u>

  • → π(3.2²)(8)
  • → 81.92π
  • → 257.36 km²

------------

hope it helps...

have a great day!!
