Hi there. To solve this question, we'll have to remember some properties about parabolas and its roots.

Given the function:

that models the height of the football Armando kicked from the ground, in feet, with respect to time x in seconds, we have to determine:

The time it takes for the ball to return to the ground after being kicked.

Let's suppose that the ball was kicked from x = 0, since the times x is given in seconds and we can't have negative time.

Before supposing it, in fact we have to determine which moments the ball was at the ground, that is, f(x) = 0. We're finding the roots of the function:

To solve this quadratic equation, remember the general solution to a quadratic equation

Is given by the formula:

Plugging a = -7, b = 38 and c = 0.22, we get:

Multiply the values, square the number and add inside the radical.

Separing the solutions and calculating their values, we get

In this case, we before had supposed the ball started from x = 0. This is not really necessary because we found that the roots of this functions are contained in the positive x-axis.

To find the time for the ball to return to the ground, we make:

Or 5.42 seconds.

Graphically, what we have is:

Answer:

48 gallons of paint are needed.

Step-by-step explanation:

Set up a proportion.

Like this: x is for the unknown number of gallons.

[tex]\frac{3}{75} = \frac{x}{1200}\\ 75(x)= 3(1200)\\ 75x=3600\\x= 3600/75\\x= 48 Answer[/tex]

The first triangle is an Isosceles triangle:

2 equal sides

2 equal angles ( opposite to the sides)

The sum of all interior angles of a triangle is 180°

So, for the left triangle:

51+x+x2 = 180

x+x2 = 180-51

x+x2 = 129

Since both angles are equal:

129/2 = 64.5°

x= 64.5°

x+y = 90°

64.5 + y = 90

y= 90-64.5

y= 25.5°

Right triangle:

25.5+25.5 +z = 180

z= 180-25.5-25.5

z= 129°

The derivative of y =  [ 1/x(x+4) - 1/(5x + 1) - 1/(3x + 7) ] is

y' =  [tex]\sqrt{\frac{x(x-4)}{(5x+1)(3x+7)} }[/tex] x 1/2  [1/x(x+4) - 1/(5x + 1) - 1/(3x + 7)]

The derivative of a function f(x) represents its rate of change.

We have,

y = [tex]\sqrt{\frac{x(x-4)}{(5x+1)(3x+7)} }[/tex]

Putting log on both sides.
[ log a² = 2 log a ]

log y = 1/2 log [tex]\frac{x(x+4)}{(5x+1)(3x+7)}[/tex]

log y = 1/2 [ log x(x+4) - log (5x +1)(3x + 7) ]

log y = 1/2 [ log x(x+4) - log(5x + 1) - log (3x + 7) ]

Derivation on both sides.

[ d(logx)/dx = 1/x ]

d (log y) / dx = d [ {1/2 log x(x+4) - log(5x + 1) - log (3x + 7)} ] / dx

1/y y' = 1/2[ 1/x(x+4) - 1/(5x + 1) - 1/(3x + 7) ]

y' = y/2 [ 1/x(x+4) - 1/(5x + 1) - 1/(3x + 7) ]

y' =  [tex]\sqrt{\frac{x(x-4)}{(5x+1)(3x+7)} }[/tex] x 1/2  [1/x(x+4) - 1/(5x + 1) - 1/(3x + 7)]

Thus,

The derivative of y =  [ 1/x(x+4) - 1/(5x + 1) - 1/(3x + 7) ] is

y' =  [tex]\sqrt{\frac{x(x-4)}{(5x+1)(3x+7)} }[/tex] x 1/2  [1/x(x+4) - 1/(5x + 1) - 1/(3x + 7)]

We are given that Brianna needs to receive $199300 and that she also needs to allow for a 3 percent commission. Let "x" be the amount Brianna needs to sell her house. We need to subtract from this amount the 3% commission. To do that we will use the following relationship:

Now, we solve for "x" first by adding the fractions using the following model:

Therefore, we will multiply the 100 from the denominator by "x" and subtract 3 from the result, like this:

Solving the operations we get:

Now we multiply both sides by 100:

Now we divide both sides by 97:

Therefore, the amount is $205463.92. Since we are told to round to the nearest hundred dollars we round the answer to $205500.

Answer:

D. 17.4 yards

Step-by-step explanation:

Since the area of the rectangle is 17.36 square yards, and the width is 3.1 yards, we set up and solve this equation to find the length:

17.36 = 3.1h, so h = 5.6 yards.

From this, the perimeter of the rectangle is 2(3.1 + 5.6) = 2(8.7) = 17.4 yards.

So D is the correct answer.

Answer:

Yes, it is a linear function.  For every input there is only 1 output.

Step-by-step explanation:

Check the picture below.

Combining the three different transformations—rotations, reflections, and translations—will result in congruent shapes. Actually, any pair of congruent shapes can be matched to one another using a combination of one or more of these three transformations.

There are four possible transformations of a point, line, or geometric figure, each of which changes the object's shape and/or location. Pre-Image denotes the shape of the object before transformation, while Image denotes the final position and shape of the object.

We now know that during rigid transformations, the size and shape of the figures are maintained (reflections, translations, and rotations). The pre-image and the image are always in agreement.

Matt has the following transformational abilities:

Reflection (Flip)

A reflection keeps its original shape because the comparable points from the pre-image to the image stay at the same distance from the line of reflection.

Rotations as a Congruence Transformation

Rotations as a Congruence Transformation

A figure twists when it rotates. The figurine looks to have fallen over, although being the same size and shape. A great illustration of a rotation in the actual world is a clock. The connecting arms of a clock rotate around its axis every hour or every day. A rotation is defined by its degree; common rotations include 90 degrees, 180 degrees, and 270 degrees. The figure completes a full 360-degree rotation before returning to its starting point. A rotation must include indicate the clockwise or counterclockwise direction. This information can be used to calculate the degree, quantity, and direction of a revolution.

Translational congruence transformation

We refer to a movement as a translation when an object or shape is moved from one place to another without changing its size, shape, or orientation. Every point on an item or shape is moved by the same amount and in the same direction during a translation, sometimes referred to as a slide.

Suppose that the relationship between the tax rate t on imported shoes and the total sales S (in millions of dollars) is given by the function below. The tax rate t that maximizes revenue for the government is 66.992%.

Revenue can be defined as the amount or the income a person or an organization generated from the sales of goods and services.

Given function :

Total sale  = S(t) = 7−6∛t

Hence,

Expression for Revenue rate = r(t) = tS(t)

Now let substitute and solve  expression

r(t) = t (7−6∛t)

= 7t−6(t)^4/3

Differentiate the expression

d[r(t)] dt = r′(t)

r′(t) = 7− (4/ 3) 6(t)^1/3

=7−8(t) ^1/3 ........ expression (1)

Maximum revenue

r′(t) = 0

Substitute and solve expression (1)

0 =7−8(t)^1/3

(t) = (7/8)^3

= 0.66992 × 100

= 66.992%

Therefore we can conclude that the tax rate t that maximizes revenue is 66.992%.

Aisha age is 5 year and Aisha's mother age is 25 year.

The formula for a linear equation is the way in which a linear equation is expressed. It can be expressed in the standard form, the slope-intercept form or the point-slope form. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is the coefficient of x, and B is a constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, and A, B, and C are any real numbers.

Given that,

Aisha's mother is 5 times older than Aisha.

Let Aisha age = x year

Aisha's mother = 5x year

After 15 years Aisha's mother will be twice the age her daughter.

5x+15 = 2(x+15)

5x+15 = 2x+30
