in a certain situation, the maximum height H, in meters, that a ball bounces is given by the equation H=3/5F=0.02, where F is the force, in newtons, with which the ball is bounced. What force, in newtons, must be applied for the height to be 0.16 meters?

Answer:

n=36

Step-by-step explanation:

To isolate n you need to subtract 15 from both sides giving you

2n=72

Then to further isolate n you need to divide 2 from both sides giving you the answer

n=36

the next one is d(v) = 2.15v^2 / 22.54

Step-by-step explanation:

i just did this assignment. also thanks to the answer above me :)

We have that the value of f, rounded to the nearest hundredth.

f_1=0.02

f_2=0.009

f_3=0.009

From the question we are told that

d(v)= \frac{2.15v^2}{64.4f}

Generally the equation for the f is mathematically given as

f= \frac{2.15v^2}{64.4*d(v)}

Therefore

For v=20 and f=38

f= \frac{2.15(20)^2}{64.4*(38)(20)}

f=0.02

For v=30 and f=86

f=\frac{2.15(30)^2}{64.4*(86)(30)}

f=0.01

For v=40 and f=153

f=\frac{2.15(40)^2}{64.4*(153)(40)}

f=0.009

The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.

Volume is the amount of space that is occupied by a three dimensional object.

The volume of a cone (V) is given by:

V = (1/3)πr²h

Where r is the radius and h is the height.

For a radius of 1:

3π = (1/3)π*(1)² * h

h = 9

For a radius of 2:

3π = (1/3)π*(2)² * h

h = 2.25

For a radius of 5:

3π = (1/3)π*(5)² * h

h = 0.36

For a radius of 12:

3π = (1/3)π*(12)² * h

h = 0.02

The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.

Answer: The answer would be c  2x + 4

Step-by-step explanation:

My first tip would be to label your triangles.

If you find our reference angle and go across, that would be our opposite side, so x is the opposite side.

The line with both the reference angle and the right angle would be our adjacent side, so 40 would be the adjecent side.

If you find the right angle and go across, that would be our hypotenuse.

//

In this problem, we are given an angle and the adjacent side and we are looking for the opposite side, so that means that we would be using our tangent ratio.

[tex]tan = \frac{opp}{adj} = \frac{x}{40} [/tex]

[tex] \tan(43) = \frac{x}{40} [/tex]

if the thing you are looking for is on the numerator, we would have to multiply. If the thing you're looking for is in the denominator, you would have to divide.

Since x is on the numerator, we would have to multiply.

[tex]x = 40 \tan(43 ) [/tex]

Answer:

The equation representing the left table is:  

y = 1.5x – 6

The equation representing the right table is:  

y = –4x + 6.1

The solution to the system of equations is:  

(2.2, –2.7)

Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The first table is

x            y

0           -6

1            -4.5

2            -3

3             -1.5

Slope = -4.5+6/1

=1.5

Now let us find y intercept

-6=1.5(0)+b

-6=b

So the equation representing the left table is y=1.5x-6

Now let us find second table

x            y

0           6.1

1             2.1

2           -1.9

3            -5.9

m=2.1-6.1/1=-4

Now y intercept

2.1=-4+b

b=2.1+4

b=6.1

Equation representing the right table is y=-4x+6.1

Now equate two equations

1.5x-6=-4x+6.1

1.5x+4x=6.1+6

5.5x=12.1

x=12.1/5.5

x=2.2

and y=-4(2.2)+6.1

y=-8.8+6.1

y=-2.7

Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

A table of values can be generated from a quadratic function by substituting the x-values and calculating the values for f(x). When looking at a table of values for a quadratic function, the x-intercepts represent the x-values where y = 0. This corresponds to the x-values where f(x) is 0 in function notation.
