A soccer ball on the ground was kicked with an initial velocity of 35 ft/sec at an elevation angle of 40º. Create a set of parametric equations to model the path of the soccer ball. Approximately how far away did the soccer ball hit the ground?


19 feet

26 feet

38 feet

52 feet

Answers

Answer:

38 feet.

Step-by-step explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 35 ft/s

Angle of projection (θ) = 40º

Acceleration due to gravity (g) = 9.8 m/s²

Range (R) =?

Next, we shall convert 9.8 m/s² to ft/s². This can be obtained as follow:

0.3048 m/s² = 1 ft/s²

Therefore,

9.8 m/s² = 9.8 m/s² × 1 ft/s²/ 0.3048 m/s²

9.8 m/s² = 32.15 ft/s²

Thus, 9.8 m/s² is equivalent to 32.15 ft/s².

Finally, we shall determine how far away the soccer ball hit the ground (i.e range) as shown below:

Initial velocity (u) = 35 ft/s

Angle of projection (θ) = 40º

Acceleration due to gravity (g) = 32.15 ft/s²

Range (R) =?

R = u² × Sine 2θ / g

R = 35² × Sine (2×40) / 32.15

R = 1225 × Sine 80/ 32.15

R = 1225 × 0.9848 / 32.15

R = 37.5 ≈ 38 feet.

Thus, the soccer ball hit the ground 38 feet away.

1. Find the (product, quotient, difference, sum) of f(x) and x + 5
2. The (quotient, remainder, sum, discriminant) of this operation is 0
3. Therefore, (x+5) is (not a factor, the opposite, a factor, the simplified form) of function f
4. So f ([-75, 5, -5, 75)] = 0

Answers

1. quotient

2.remainder

3. a factor

4. 5

Step-by-step explanation:

i just took the test

The expression (x + 5) is a factor of given function f(x).

So the remainder of the function will be zero.

Remainder theorem:

The given function is,

                      [tex]f(x) = x^3 + 3x^2 - 25x - 75[/tex]

We have to check (x + 5) is a factor of the given function.

Equate (x + 5) is equal to 0.

           x + 5 = 0

                 x = -5

Substitute x = -5 in given equation.

          [tex]f(-5)=(-5)^3+3(-5)^2-25(-5)-75\\\\f(-5)=-125+75+125-75\\\\f(-5)=0[/tex]

Since f(-5) = 0. Therefore, (x + 5) is a factor of given function f(x).

Just think about 1) 60 is the new temperature, in order to have an addition problem we're going to have to use negative numbers. Since we had to subtract 20, in order to use addition it would be 80+(-20).

$142,162
$13,616
$14,720

Answers

Answer:

$13,616

Step-by-step explanation:

For each year we will have to constantly decrease it by 7.5%

23,500 - 7.5%

= 21,737.5

= 21,737.5 - 7.5%

= 20,107.1875

= 20,107.1875 - 7.5%

= 18599.1484375

= 18599.1484375 - 7.5%

= 17204.2123047

= 17204.2123047 - 7.5%

= 15913.8963818

= 15913.8963818 - 7.5%

= 14720.3541532

= 14720.3541532 - 7.5%

= 13616.3275917

Definitively we will get the answer $13,616

at a basketball game at team made 58 successful shots they were a combination of one and two point shots the team scored 98 points in all right and solve a system of equations to find out the number of each type of shot

Answers

Answer:

There were 18 1 point goals and 40 2 point goals

Step-by-step explanation:

Let the number of one point shots be x and the number of two point shots be y

Total number of shot is 58

x + y = 58 ••••(i)

Then;

Total of 1 point is 1 * x = x

Total of 2 points is 2 * y = 2y

x + 2y = 98 ••••••(ii)

x = 98-2y

Put this in 1

98-2y + y = 58

-y = 58-98

y = 40

x = 58-40

x = 18

Water flows down the Mississippi river at about 1.2 miles per hour. The relationship between hours and miles the water has traveled is... Discrete or continuous

Answers

Answer:

Continuous

Step-by-step explanation:

Given

[tex]Rate = 1.2\ miles/hour[/tex]

Required

Determine if this relationship is discrete or continuous

Numbers in their whole form (i.e. 1,2,3.....) represent discrete values while others with decimals (such as 0.2,0.9, 1.2...) represent continuous values

From the above analysis, we can see that 1.2 fall in the category of continuous values.

Hence, the relationship between both parameters is continuous

Carrie and Alex are playing hide and seek Alex stands at the house to count Carrie runs 25 m west and finds nowhere to hide. She Continues 60 m north to the tree

Answers

Answer:

65m

Step-by-step explanation:

Since we are not asked what to find, we can as well calculate the displacement of Carrie.

Displacement will be gotten using Pythagoras theorem;

Given

direction through west x = -25m

direction through north y = 60m

Required

Displacement d

According to the theorem;

d² = x²+y²

d² = (-25)²+(60)²

d² = 625 + 3600

d² = 4225

d = √4225

d = 65 m

Hence the displacement of Carrie is 65m
