The quadratic equation y=-0.5x+4x+10 models the path of a heavy ball through the air, where y represents the height in feet and x represents time in seconds. When will the ball hit the ground?

Answers

We have been given that the quadratic equation $y=-0.5x^2+4x+10$ models the path of a heavy ball through the air, where y represents the height in feet and x represents time in seconds. We are asked to find the time when ball will hit the ground.

The ball will hit the ground, when height of ball above ground will be 0. So we will equate our given quadratic equation with 0 and solve for x.

$-0.5x^2+4x+10=0$

We will use quadratic formula to solve our given problem.

$x=(-b\pm√(b^2-4ac))/(2a)$ , where

b = Coefficient of x term,

a = Coefficient of $x^2$ term,

c = Constant.

$x=(-4\pm√((-4)^2-4(-0.5)(10)))/(2(-0.5))$

$x=(-4\pm√((16+20))/(-1)$

$x=(-4\pm√(36))/(-1)$

$x=(-4\pm6)/(-1)$

$x=(-4+6)/(-1), x=(-4-6)/(-1)$

$x=(2)/(-1), x=(-10)/(-1)$

$x=-2,x=10$

Since time cannot be negative, therefore, the ball will hit the ground after 10 seconds.

Answers

Given:

$\text{Function}=\{(3, -2), (6, 1), (-1, 4), (5, 9), (-4, 0)\}$

To find:

The domain of the given function.

Solution:

Domain is the set of input values or x-values.

In the given function, the x-coordinates of ordered pairs are 3, 6, -1, 5 and -4. So, domain is the set of these values in ascending order.

The set builder form of domain is

$\text{Domain}=\{x|x=-4,-1,3,5,6\}$

Therefore, the correct option is C.

The area of a rectangular wall of a barn is 55 square feet. It's length is 6 feet longer than the width. Find the length and width of the wall of the barn.

Answers

x - width
x+6 - length

$x(x+6)=55\n x^2+6x-55=0\n x^2+11x-5x-55=0\n x(x+11)-5(x+11)=0\n (x-5)(x+11)=0\n x=5 \vee x=-11$

x=5 feet
x+6=11 feet

Final answer:

The dimensions of the barn wall are found by setting up and solving a quadratic equation involving its area and the relationship between its length and width. Discarding the nonsensical negative solution, we find that the width of the wall is 5 feet and the length is 11 feet.

Explanation:

Given that the area of the rectangular wall is 55 sq. ft. and the length is 6 ft. longer than the width, we can assign the width as x and the length as x + 6. Therefore, length multiplies width equals to the area of the rectangle, we then have the equation: x * (x + 6) = 55.

After rearranging the equation, we obtain: x² + 6x - 55 = 0. This is a quadratic equation that we can solve using the quadratic formula or by factoring if possible. Factoring results in (x - 5)(x + 11) = 0. Setting each factor equal to zero gives the possible solutions x = 5 and x = -11.

However, since the dimensions of a physical object (in this case, width of the barn wall) cannot be negative, we discard x = -11. Therefore, the barn wall has a width of 5 feet and a length of 5 + 6 = 11 feet.

Hi please help me I'm confused If 8% of a number is 4, what is 12% of a number? Explain your reasoning.

Answers

Answer:

Step-by-step explanation:

The easiest way of solving this is to divide 8% of the number into a % that is divisible by 12.

This is 4%.

So if 8% of the number is 4, then 4 percent is half of 4, that is 2.

Now we convert 4% into 12% thus making it 6

Hope this helps

A more complicated way of doing this, but most reliable is to work out what the number is .

For now let number be y.

8/100 x y = 4

8y/100 = 4

8y= 400

y = 50.

Now calculate 12% of 50.

This is

12/100 x 50 = 6

Hope this helps.

6 is 12 % of a number.
