Depending on if you know the diameter or the radius the formulas are: Circumference = pi x diameter or pi x 2 x radius


1. 3.14 x 8 ft = 25.12 ft.


2. 3.14 x 2 x 7in. = 3.14 x 14 = 43.96 in.


3. 3.14 x 18 yds. = 56.52 yds.

3.920 * (1.018)^x = 5.500<br><br>X=?​
Andrei [34K]

Answer:

19

Step-by-step explanation:

3.920(1.018)ˣ = 5.500

  • First we can divide both sides by 3.920 to get: (1.108)ˣ = 1.403
  • Then we can take the natural log of both sides to get: ln[(1.108)ˣ] = ln(1.403)
  • We can then use logarithmic rules to move the x exponent to the front: xln(1.108) = ln(1.403)
  • Then we can divide both sides by ln(1.108) to get: x=\frac{ln(1.403)}{ln(1.018)}
  • Then using a calculator we get x = 18.98 ≈19

A projectile is shot vertically from the ground level. It’s height h, in feet, after t seconds is given by h = 88t - 16t ^2. How
kozerog [31]

Answer:

it will take 5.5 seconds to hit the ground

Step-by-step explanation:

A projectile is shot vertically from the ground level. It’s height h, in feet, after t seconds is given by h = 88t - 16t ^2

When the projectile hits the ground then the height becomes 0

h = 88t - 16t ^2

0 = 88t - 16t ^2

GCF is -8t

0 = 8t(11 - 2t)

now set each factor =0 and solve for t

8t=0, t=0

11-2t=0, t=\frac{11}{2}

So it will take 5.5 seconds to hit the ground

Finding angle measures between intersecting lines
grin007 [14]

Answer: 60° angle

Step-by-step explanation: AGD is a 90° angle, therefore, subtracting 30 from the 90 degrees gives you 60. As x is vertical to the 60 degree angle and verticals have the same degree measurement, x=60°.
