A Particle Moves Along The X-axis So That Anytime T Comma Measured In Seconds It's Position Is Given

Answers

Answer 1

Given the position function s(t), you can get the acceleration function by differentiating s twice:

velocity = s'(t) = -5 sin(t ) + 3 cos(3t )

acceleration = s''(t) = -5 cos(t ) - 9 sin(3t )

Then when t = π, the particle's acceleration is

s''(π) = -5 cos(π) - 9 sin(3π)

… = -5 • (-1) - 9 • 0 = 5

Answers

Answer:

a = 1.8 cm

Step-by-step explanation:

Here. we want to find the value of a

To do this, we are going to use the sine rule

it states that the ratio of a side and the sine of the angle that faces the side is a constant for all the sides of a triangle

From the diagram, we have that;

The angle facing a is;

180-15-105 = 60

So, we have that

a/sin 60 = 2/sin 105

a = 2sin 60/sin 105

a = 1.794 cm

What is the area of a circle?

The area of a circle is defined as the space occupied by the circle in a two-dimensional plane. In other word, the space occupied under the region or circumference of a circle is called the area of the circle.

The formula for the area of a circle is A = πr²,

Where r is the radius of the circle.

For example, if the radius of circle is 6cm, then its area will be: Area of a circle with 6 cm radius = πr² = π(6)² = 36π square cm.

Given data as :

A = 1/2 πr²

Solve for pi

⇒ A = 1/2 πr²

Multiply by 2 both the side

⇒ 2A =  πr²

⇒ 2A/r² =  π  or

⇒  π = 2A/r²

If A = 76 cm² and π  = 22/7,

⇒ A = πr²

⇒ A/π = r²

⇒ √A/π = r

Substitute the values, we have:

⇒ √76 /(22/7) = r

⇒ √76 * 7/22 = r

⇒ √532/22 = r

⇒ √24.1818 = r

⇒ 4.917 = r

⇒ r = 4.92 cm (Rounding to two decimal places)

Jasmine sold half of her Barbie doll Collection
and then bought 9 dolls. She now has 13 dolls.
Barbie dolls did she begin with?
How many

Answers

Answer: 8 dolls.

Explanation: 13 - 9 = 4, 4 x 2 = 8.

Work the equation backwards... she has bought 9 extra dolls to add on the the half of her original amount. Without the extra 9 dolls (13 - 9), Jasmine has half of her original amount left (4) and so to find the original amount of dolls, think that if 4 is half the amount, what is 4 half of? 4 is half of 8 and so 8 is the original amounting dolls she had.

On a team 5 girls and 2 boys scored a total of 41 points. The difference between the number of points scored by the 5 girls and the number of points scored by the
2 boys is 29. Each girl scored the same number of points and each boy scored the same number of points. Find the number of points scored by each girl and each
boy
Each girl scored points

Answers

Step-by-step explanation:

Let x be the number of points the 5 girls scored.

=> 41 - x is the number of points the 2 boys scored.

We have x + 29 = 41 - x or x - 29 = 41 - x.

=> 2x = 12 or 2x = 70

=> x = 6 or x = 35

We reject x = 6 as 6 is not a multiple of 5. (Each girl would have scored 1.2 points which is absurb)

So x = 35, each girl scored 35/5 = 7 points.

=> 41 - (35) = 6, each boy scored 6/2 = 3 points.

Answers

Answer:

see explanation

Step-by-step explanation:

(3)

The opposite sides of a parallelogram are congruent, so

6x = 3x + 15 ( subtract 3x from both sides )

3x = 15 ( divide both sides by 3 )

x = 5

and

2y - 10 = y + 5 ( subtract 5 from both sides )

y - 10 = 5 ( add 10 to both sides )

y = 15

Then x = 5 and y = 15

-------------------------------------------------------------------------

(4)

The diagonals of a parallelogram bisect each other, thus

y = 4x - 6 → (1)

9x - 25 = 2y → (2)

Substitute y = 4x - 6 into (2)

9x - 25 = 2(4x - 6)

9x - 25 = 8x - 12 ( subtract 8x from both sides )

x - 25 = - 12 ( add 25 to both sides )

x = 13

Substitute x = 13 into (1)

y = 4(13) - 6 = 52 - 6 = 46

Then x = 13 and y = 46
