Answer:

2.5

Step-by-step explanation:

The radius is any line from the middle of the circle to the end of the circle. The diameter is a chord which is a line going from any end of the circle to the other end but the diameter crosses though the point which is in the middle.

So, you split the diameter in half. 5/2 = 2.5

Graphs of exponential functions
Valentin [98]

An example of an exponential graph function has been attached and its' properties are as below.

<h3>How to draw the graph of an exponential function?</h3>

The general formula for exponential functions is: f(x) = aˣ, a > 0, a ≠ 1.

The reasons for the restrictions are because;

If a ≤ 0, then when you raise it to a rational power, you may not get a real number.

The graph of an exponential function y = 2ˣ is shown in the attached file. Here are some properties of the exponential function when the base is greater than 1.

  • The graph passes through the point (0,1)
  • The domain is all real numbers
  • The range is y>0.
  • The graph is increasing
  • The graph is asymptotic to the x-axis as x approaches negative infinity
  • The graph increases without bound as x approaches positive infinity
  • The graph is continuous
  • The graph is smooth

60% of a museum’s fossils are from the Jurassic Period. If the number of fossils from the Jurassic period is 15, what is the tot
Keith_Richards [23]

Answer : The total number of fossils at the museum are, 25

Step-by-step explanation :

As we are given that 60% of a museum’s fossils are from the Jurassic Period.

Let the total number of fossils at the museum be, 'x'

Given:

Number of fossils from the Jurassic period = 15

The % of a museum’s fossils are from the Jurassic Period = 60%

Thus, the expression will be:

\frac{15}{x}\times 100=60

By solving the term 'x' we get:

x=\frac{15}{60}\times 100

x=25

Thus, the total number of fossils at the museum are, 25

For what values of t can 3(x^2) + tx + 8 be written as the product of two binomials and what are the pairs of binomials?
Alekssandra [29.7K]
Answer:

The pair of binomials are;

(x+1)(3x+8)

and

(x-1)(3x-8)

Step-by-step explanation:

The given expression is  3x^2+tx+8.

If the given quadratic trinomial can be factored as two binomials, then,

By comparing to ax^2+bx+c, we have a=3,b=t,c=8

We find ac=3\times8=24

We also know that; -3\times -8=24

This implies that;

t=8+3=11 or t=-3-8=-11

When t=11;

3x^2+11x+8

When we factor this we obtain;

(x+1)(3x+8)

When t=-11;

3x^2-11x+8

When we factor this we obtain;

(x-1)(3x-8)
