Since distance is a function of time, then the range must be the possible time that Heather could spend with her mountain bike.

Given that she can travel for period 32 minutes and that there can be no negative time. The answer is:
2. 0 ≤ f(t) ≤ 32

To answer the problem above, we must interpret each given ranges in words.
1. If the time is greater than or equal to zero, the distance would be less than or equal to 6 miles.
2. If the time is less than or equal to 32 minutes, the distance would be greater than or equal to 0 miles
3. If the time is less than or equal to 32 minutes, the distance would be greater or equal to 6 miles
4. If the time is less than or equal to 24 minutes, the distance would be greater or equal to 12 miles.

The reasonable range is No. 2 .

<u>Answer:</u>

The variable that has the highest power is considered to be the degree of polynomials in an algebraic equation.

A column:

1) 4x^3 .

The degree is 3.

2)x^2+4.

The degree is 2.

3) x-2

The degree is 1.

B column:

1) 2x^2+1

The degree is 2.

2) x^2-x

The degree is 2.

3) x^3-5x^2+1

The degree is 3.

A×B columns:

While Multiplying two terms in a equation, if the variables are same then multiply the constant value and sum the exponent value.

1) (4x^3)(2x^2+1).

=8x^5+4x^3.

The degree is 5.

2) (x^2+4)(x^2-x).

=x^4-x^3+4x^2-4x.

The degree is 4.

3) (x-2)(x^3-5x^2+1).

=x^4-5x^3+x-2x^3+15x^2-3.\\=x^4-7x^3+15x^2+x-3.

The degree is 4.

A probability experiment is conducted in which the sample space of the experiment is S={1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.
Snezhnost [94]

Answer:

The answer is " \bold{\frac{2}{3}}"

Step-by-step explanation:

Given set:

\to F \ or\  G = \{ 5,6,7,8,9,10,11,12\}

In the above-given set, there are 8 elements and 12 possible outcomes so, the equation is:

\to P( F\ or \ G) = \frac{8}{12}

                      = \frac{2}{3}

by using the general addition Rule:

\to P(F \cup G) = P(F) +P(G)- P(F \cap G)

                    =\frac{5}{12}+\frac{4}{12}- P(E \cap H)\\\\=\frac{6}{12}+\frac{3}{12}- \frac{1}{12}\\\\=\frac{6+3-1}{12}\\\\=\frac{8}{12}\\\\=\frac{2}{3}\\\\

I’m reviewing for a state test plz help I know it’s keep change flip but what do we get and what’s the letter
andrew-mc [135]
The correct answer is C 4/9 x 8
This is because when dividing fractions, flip the second fraction and then change the division sign to multiplying sign
Hope this helps!

Which undefined terms are needed to define a line segment?
solmaris [256]
<span>The correct answer is point and line.

Explanation:
These are two of the fundamental undefined terms in geometry. A line segment is a part of a line that has two defined points at each end; therefore "line" and "point" are used in the definition.</span>
