Question 33 Of 45 You May Use Your Calculator For This Question. A Particle Moves Along A Line So That

Answers

Answer 1

The particle's velocity at time [tex]t[/tex] is equal to the first derivative of its position at that time, and acceleration is the second derivative.

We have

[tex]s(t) = -4\sin(t) - \dfrac t2 + 10 \implies s'(t) = -4\cos(t) - \dfrac12 \implies s''(t) = 4\sin(t)[/tex]

Find when the velocity is zero:

[tex]s'(t) = -4\cos(t) - \dfrac12 = 0 \implies \cos(t) = -\dfrac18 \implies t = \cos^{-1}\left(-\dfrac18\right) \approx 1.696[/tex]

At this time, the acceleration of the particle is approximately

[tex]s''(1.696) \approx \boxed{3.969}[/tex]

The total distance if Pete walks from A to B to C is 40 yards, the direct distance from A to C is more than 10 yards, and an inequality w < 30

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

Points A, B, and C, form a triangle. The distance between point A and point B is 15 yards. The distance between point B and point C is 25 yards.

Total distance if Pete walks from A to B to C:

= 15 + 25 = 40 yards

As we know in the triangle the sum of the two sides is greater than the third side.

25 + 15 > AC

The direct distance from A to C is more than 10(25-15) yards.

The inequality w < 30 represents the distance, w, that Pete might save by taking the direct path.

Thus, the total distance if Pete walks from A to B to C is 40 yards, the direct distance from A to C is more than 10 yards, and an inequality w < 30

capital income at age 40 * income

= 2.4 * 32000

Capital = $76800

The correct answer is option B which is (-4-√11) and (-4+√11).

What is inequality?

Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

The inequality is given as x² + 8x + 5 < 0 for we will draw a graph of the inequality and find the range of x which ranges from ( -7.31,- 0.68) So these points in the options will be equal to (-4-√11) and (-4+√11).

Step-by-step explanation:

if 12 pieces combine to make x, [we know they are identical], each piece must be 1/12 of x [1/12·x = x/12]

(think of it like this: "x" length must be divided amongst 12 pieces, so, we divide x/ 12)

Timber=x/12

Step-by-step explanation:

12 pieces long is x, if the length of each one is same, so the length of each one is x/12.

Which step in the construction of copying a line segment ensures that the new line segment has the same length as the original line segment

Answers

Now out of these points, steps 5 and 6 are the main steps that ensure that the copied line segment is exactly the same as the original segment.

The steps to copy a line segment are given below:

1. Let's start with a line segment AB that we have to copy.

2. Now mark a point C. Below or above AB, which will be one endpoint of the new line segment.

3. Now, put the compass tip on point A of the line segment AB.

4. Spread the compass up to point B, so that the compass width is equal to the length of AB.

5. Without changing the compass width, now place the compass tip on point C that you made in step 2.

6. Now, draw an arc roughly without changing the compass settings. Mark that point D. This will form the new line segment.

7. Draw a line from C to D.

Solve the Proportion.
10/a = 15/24
a=?

Answers

Answer:

a=16

Step-by-step explanation:

10/a=15/24, a≠0

10/a=5/8

80=5a

5a=80

a=16,a≠0

a=16

a = 16. How did I get this? Well, 15/24 is a reducible fraction itself. When reducing the fraction 15/24, we divide the numerator and denominator by 3 to get 5/8. Now that we have 5/8 as our simplified fraction, the expression is:

10/a = 5/8

Because 10 divided by 2 equals 5, we could multiply 8 by 2 to get what our denominator that is missing would be. 8 x 2 = 16, so a = 16. 10/16 = 15/24.

Your final answer: a = 16

-11y=11

y=-1

x-3y=-5

x+3=-5

x=-8

Answer: x = -8 and y = -1

Step-by-Step Solution:

=> x + 8y = -16 (Eq. 1)
=> x - 3y = -5 (Eq. 2)

Subtracting Eq. 2 from 1, we get :-

8y + 3y = -16 + 5
11y = -11
y = -11/11
=> y = -1

Therefore, y = -1

Substitute value of ‘y’ in Eq. 2 :-

x - 3y = -5
x - 3(-1) = -5
x - -3 = -5
x + 3 = -5
x = -5 - 3
x = -5 + -3
=> x = -8

Therefore, x = -8

Hence, x = -8 and y = -1 (-8, -1)
