Answer: 89

Step-by-step explanation:

A triangle always equal 180 degrees

so first add the measurements you know

PLEASE HELP!!! The amount of polonium-210 remaining, P(t), after t days in a sample can be modeled by the exponential function P

exis [7]

Answer:

$P(t)=100(0.994)^t$

Step-by-step explanation:

A calculator shows the value of $e^{-.006} \approx 0.994$ meaning that each day, about 99.4% of the sample remains.

The formula $P(t)=100e^{-0.006t} = 100(e^{-0.006})^t=100(0.994)^t$

Evaluate this at <em>t</em> = 16 to get 91 grams remain.

Answer:

207.24 in²

Step-by-step explanation:

The "r" in the formula stands for the radius of the cylinder. That is half the diameter, so is 3 in. The "h" in the formula stands for the cylinder height, shown as 8 in. Put these values in the formula and do the arithmetic.

SA = 2πr(r +h) = 2(3.14)(3 in)(3 in + 8 in) = 6.28(33 in²)

SA = 207.24 in²

Answer: hypotenuse = $c^{2} + b^{2}$

Step-by-step explanation: Pythagorean theorem states that square of hypotenuse (h) equals the sum of squares of each side ( $s_{1},s_{2}$ ) of the right triangle, .i.e.:
