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

Find a.
Round to the nearest tenth:
2 cm
с
150
1050
a =
= [? ]cm
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
5/7(14-21x)=115

Two cars leave the same parking lot, with one heading north and the other heading east.
After several minutes, the eastbound car has traveled 3 kilometers. If the two cars are now a
straight-line distance of 6 kilometers apart, how far has the northbound car traveled? If
necessary, round to the nearest tenth.
Answer:
wouldn't it be 3 kilometers because 3 this way plus 3 that way = 6 away from each other?

The solution for pi is π = 2A/r² where r is the radius.
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)

what subtracted by 26 equals -102
Answer:
-76
Step-by-step explanation:
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
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.

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
