Which of the following is described below?

This object goes forever in opposite

directions. It is infinitely skinny, as it is a

set of points that are all lined up.

A. Point

B. Line

C. Ray

D. Segment

**Answer:**

B. line

**Step-by-step explanation:**

A line would fit this description best. A ray wouldnt work because it goes on infinitely in one direction. A point wouldnt work because it is a dot that marks a location, and a segment is bound by 2 points, and cannot go on forever.

The given description would be best fitting to a "**line**", which is the correct **answer **would be an **option **(**B**).

A Line is formed by a set of **points **traveling in a straight line but in opposite directions. It has no breadth, no depth (**curvature**), and no termination, which implies 'it will not finish,' hence it moves in a **straight line **in opposing **directions **indefinitely.

This object goes forever in opposite directions. It is infinitely skinny, as it is a set of points that are all lined up.

This description would be best suited to a **line**.

A ray would not operate since it extends in one direction **indefinitely**. A point would not work since it is a dot that indicates a position, but a **segment **is constrained by two **points **and cannot continue indefinitely.

Hence, the correct answer would be an option (B).

1. There are 2 hiking trails in Watkins Park. The Spicebush Trail is 2.7 miles and the Loop Trail is 1.7 miles. If you hiked both trails, how many miles would you walk?

2. On your hike, you brought 1.7 pounds of almond trail mix and 1.4 pounds of cashew trail mix. How much trail mix do you have all together?

3. At the end of the hike you still had 2 pounds of trail mix left. How much trail mix did you at on the hike?

4. Solve these decimal addition and subtraction problems with your base-10 blocks or a number line:

5.3 + 7.4

2.45 + 3.95

2.5 – 1.3

4.12 – 2.80

1. Add 2.7 and 1.7 together to discover the total amount

2.7 + 1.7 = 4.4

You would walk 4.4 miles if you walked both trials.

2. Add the amounts of both trail mixes together

1.7 + 1.4 = 3.1

There were 3.1 pounds of trail mix brought on the hiking trip

3. Subtract answer from 2 by 2 and recieve the answer for this question

3.1 - 2 = 1.1

There were 1.1 pounds of trail mix eaten on this hiking trip

A cart is slowing down at a rate of 2t + 60 centimeters per second per

second (where t is the time in seconds).

By how many centimeters per second does does the cart slow

down between seconds 5 and 15?

The **cart slows** that at the **rate of 20cm/s **between **5 and 15secs**

**Given** the r**ate function** expressed as:

r(t) = 2t + 60

If the time is **t = 5**

r(5) = 2(5) + 60

r(5) = 70cm/s

If the time is** t = 15**

r(15) = 2(15) + 60

r(15) = 90cm/s

Taking the **difference in rate;**

Difference = 90cm.s - 70cm/s

Difference = 20cm/s

Hence the **cart slows** that at the **rate of 20cm/s **between **5 and 15secs**

A polynomial function has a zero at x = 1 with a multiplicity of 3 and a zero at x = -2 with a multiplicity of 1. The y – intercept for the function is (0, -8). Write an equation for this polynomial.

**Answer:**

f(x) = 4(x -1)^3·(x +2)

**Step-by-step explanation:**

Each root x=p indicates the function has a factor (x -p). The factor will be repeated according to the multiplicity of the root.

f(x) = a(x -1)^3·(x +2)

f(0) = a(-1)^3·2 = -2a = -8 ⇒ a = 4

The factored form of the equation is ...

** f(x) = 4(x -1)^3·(x +2)**

The sum of 7/8 of a number and 20 is 34 at minimum

**Answer:**

7/8x ≥ 14

**Step-by-step explanation:**

(sum means addition in case you forgot)

You would start by writing 7/8x + 20 ≥ 34

You would then subtract 20 from both sides to isolate the variable x.

You would then have 7/8x ≥ 14

slope-intercept form?

Write your answer using integers, proper fractions, and improper fractions in simplest form.

**Answer:**

y=4x+2

**Step-by-step explanation:**

So we start with the slope, which is bad.

But I have an idea

lets write it as

y=4x+? and since x=1 and y=6

6=4+?

Therefore, the y, intercept must be two

**Answer:**

y=4x+2

**Step-by-step explanation:**

y-y1=m(x-x1)

y-6=4(x-1)

y=4x-4+6

y=4x+2

For what values of k

If y = cos(kt), then its first two derivatives are

y' = -k sin(kt)

y'' = -k² cos(kt)

Substituting y and y'' into 49y'' = -16y gives

-49k² cos(kt) = -15 cos(kt)

⇒ 49k² = 15

⇒ k² = 15/49

⇒ **k = ±√15/7**

Note that both values of k give the same solution y = cos(√15/7 t) since cosine is even.

A restaurant has two sizes of milkshakes, small and regular. The ratio of small milkshakes purchased to regular milkshakes purchased is 14 to 6. What percent of milkshakes purchased are small?

**Answer:**

70%

**Step-by-step explanation:**

the ratio is 14 to 6 so if you have 14 small milkshakes you would also have 6 regular milkshakes

to find a percentage we can buff up the ratio to add up to 100

14 + 6 = 20

100 / 20 = 5

that means we must multiply each side by 5

14 * 5 = 70

6 * 5 = 30

the ratio is now 70 to 30

you would have 70% of milkshakes that are small
