Answer:

Circle diameter = 1.6 Cm

Detailed explanation:

Information provided:

Distance from the first to the third coin = 3.2 cm

Question to solve:

What is the diameter of each coin?​

Calculations:

Total number of circles = 3

According to the diagram, the space between the first and third coins measures 3.2 cm.

Thus,

Space = radius of the 1st circle + diameter of the 2nd circle + radius of the 3rd circle

Space = radius of the 1st circle + 2 (radius) + radius of the 3rd circle

Space = R + 2R + R

3.2 Cm = 4 R

Radius = 0.8 Cm

Diameter = 2 × radius

Diameter = 2 × 0.8

Diameter = 1.6 Cm

A car with an initial cost of $23,000 is decreasing in value at a rate of 8% each year. Write the exponential decay function des
tester [12383]

Answer:

Step-by-step explanation:

We will utilize the exponential decay formula described as

A = P(1 - r/n)^(nt)

Where

A symbolizes the value after a time period t.

n refers to the timeframe for value loss calculation

t indicates the number of years.

P stands for the population value.

r indicates the rate of decrease.

Based on the provided data,

P = 23000

r = 8% = 8/100 = 0.08

n = 1

Thus, the exponential decay function fitting this situation is

A = 23000(1 - 0.08/n)^1)^ t

A = 23000(0.92)^t

If A = 15000, it follows that

15000 = 23000(0.92)^t

0.92^t = 15000/23000 = 0.6522

Taking logarithm of both sides to base 10

Log(0.92^t) = log(0.6522)

t log(0.92) = log(0.6522)

- 0.036t = - 0.1856

t = - 0.1856/- 0.036

We find t = 5 years rounded to the nearest year

Which polynomial function could be represented by the graph below?
AnnZ [12381]
According to the graph, which depicts a parabola, we can determine that the function will be quadratic. First, we identify the zeros as x=2 and x=4. Next, we can form the function using a point to solve for 'a'. For instance, at x=3 and y=-3, we can find 'a.' Plugging back into the equation, we can perform necessary multiplications to reach the final function.
