The amount of carbon-14 in an object is given by y = ae– 0.00012t where a is the initial amount of carbon and t is the age in ye
Reptile [31]

Answer:

The approximate age of the bone is approximately 11552 years.

Step-by-step explanation:

The current proportion of carbon-14 with respect to its original amount is defined by following formula:

\frac{y}{a} = e^{-0.00012\cdot t} (1)

Where:

y - Current amount of carbon-14, no unit.

a - Initial amount of carbon-14, no unit.

t - Time, in years.

If we know that \frac{y}{a} = 0.25, then the approximate age of the bone is:

t = -8333.333\cdot \ln \frac{y}{a}

t\approx 11552.453\,yr

The approximate age of the bone is approximately 11552 years.

tom takes a taxi to work. There is an initial fee of $2.20. Each mile is calculated at $1.50. If Tom's final cost for the taxi i
Fudgin [204]

Fee for distance = total fee - initial fee = 12.70-2.20 = $10.50

Now, for 1 mile = $1.50

for x miles = 10.50/1.50 = 7

So, tom travel 7 miles.

The team mascot shoots a rolled T-shirt from a special T-shirt cannon to a section of people in the stands at a basketball game.
Svet_ta [14]
For this parabola we have:
f ( 0 ) = 8
and : f ( 1 ) = 24
In the first equation ( A) :
f ( 0 ) = - 16 * ( 0 - 1 )² + 24 = - 16 * 1 + 24 = 8 ( correct )
f ( 1 ) = - 16 * ( 1 - 1 )² + 24 = 24  ( correct )
For B:
f ( 0 ) = - 16 * ( 0 + 1 )² + 24 = - 16 + 24    = 8  ( correct )
f ( 1 ) = - 16 * ( 1 + 1 )² + 24 = - 16 * 4 + 24 = - 64 + 24 = 40 ( false )
For C:
f ( 0 ) = - 16 * ( 0 - 1 )² - 24 = - 16 - 24 = - 40 ( false )
f ( 1 ) = - 16 * ( 1 - 1 )² - 24 = - 24  ( false )
For D:
f ( 0 ) = - 16 * ( 0 + 1 )² - 24 = - 16 - 24 = - 40 ( false )
f ( 1 ) = - 16 * ( 1 - 1 )² - 24 = - 24   ( false )
Answer:
A )  f ( t ) =  - 16 * ( t - 1 )² + 24

Which set of shapes contains members that are always similar to one another?.
Viefleur [7K]
Answer: Equilateral triangles.

Explanation: We know that in similar polygons, its all the corresponding angles are congruent. Only the set of equilateral triangles contains members that are always similar( by AAA similarity criteria) to one another as the measure of all the angles of equilateral triangle is fixed i.e. 60°.
Rest other do not have fixed measure for angles in it.
