Answer:

B

It can not be c or d because you can't combine unlike factors. It is not a because 0.07 * 4K is not 2.8K

The correct answer is B

We can simply solve to see if it is correct.

Apply the distributive property.

.7*4k-.7*12

2.8k-8.4

This matches the example given in the question.

Hope this helps!

Enzo is studying the black bear population at a large national park.
Naddik [55]

Answer:

2,973

Step-by-step explanation:

The black bear population B(t), in the park is modeled by the following function:

B(t) = 2500 \cdot 2^{0.01t}

Where t is the time(in years) elapsed since the beginning of the study.

We want to determine the black bear population in 25 years time, t=25.

B(25) = 2500 \cdot 2^{0.01*25}\\=2973.02\\\approx 2973

There will be 2,973 black bears in 25 years time.

The table below shows some inputs and outputs of the invertible function f with domain all real numbers.
Naddik [55]

by the inverse function definition, we will have that:

  • f⁻¹(-2) = 3
  • f⁻¹(1) = 0

<h3>How to find the values of the inverse function?</h3>

Remember that, by definition, for an invertible function f(x) we have that:

f(x) = y

then:

f⁻¹(y) = x

Where f⁻¹(x) is the inverse function of f(x).

Now, we want to find:

f⁻¹(-2)  and f⁻¹(1)

If you look at the given table, we can see that we have the points (3, -2) and (0, 1), which means that:

f(3)= -2

f(0) = 1

Then, by the inverse function definition, we will have that:

  • f⁻¹(-2) = 3
  • f⁻¹(1) = 0

Describe lengths of three segments that could not be used to form a triangle
Tanya [424]
I don't understand, but, two form a triangle your two SHORTEST sides have to equal LARGER than your LONGEST side. Example: 2,3,4 
The two shortest sides are 2 and 3. 2+3=5 Is the sum greater than the largest side,4,? Yes, therefore it makes a triangle.
