Answer:

  • - 2.71

Step-by-step explanation:

  • 2· 4^{v + 4} + 20 = 32
  • 2· 4^{v + 4} = 12
  • 4^{v + 4} = 6
  • (v + 4) log 4 = log 6
  • v + 4 = log 6 / log 4
  • v + 4 = 1.29  (<em>rounded</em>)
  • v = 1.29 - 4
  • v = - 2.71

Tanya stores her coins in a cylindrical container. The container has a diameter of 8 inches and a height of 15 inches. Which is
aleksley [76]

Answer:

754 inches³

Step-by-step explanation:

The equation for the volume of a cylinder is V = π*r²*h.

So you have d = 8 (meaning r = 4) and h = 15. Substitute in those values into the equation and you'll get V = π*4²*15 = 753.98, which rounds to 754 inches³

Use the distance formula to find the distance between (1 3) and (-2 9) rounded to the nearest hundredth
frosja888 [35]

Answer:

D = 6.71

Step-by-step explanation:

The distance formula is D = \sqrt {(x_{2} -x_{1})^{2} +(y_{2} -y_{1})^{2} }

Decide which point will be Point 1 and Point 2.

Point 1: ( 1,3 )          x₁ = 1     y₁ = 3

Point 2: (-2, 9)       x₂ = -2   y₂ = 9

Substitute the information into the formula.

D = \sqrt {(x_{2} -x_{1})^{2} +(y_{2} -y_{1})^{2} }

D = \sqrt {(-2 -1)^{2} +(9 -3)^{2} }    Simplify within the brackets

D = \sqrt {(-3)^{2} +(6)^{2} }   Square each number

D = \sqrt {9 +36 }     Add

D = \sqrt {45 }   Exact answer as a radical (root number)

D = 6.708....    Answer in decimals

D = 6.71   Rounded answer to nearest hundredth

The nearest hundredth is the second place value. It rounds up because the value after it is "8", which is greater than 4.
