[tex]y=\frac{9}{16}(x-5)^2-8[/tex]

Step-by-step explanation:

The equation in vertex form is [tex]y=a(x-5)^2-8[/tex].

Substituting in the coordinates [tex](1,1)[/tex] to solve for [tex]a[/tex],

[tex]1=a(1-5)^2-8 \\ \\ 1=16a-8 \\ \\ 9=16a \\ \\ a=9/16[/tex]

Step-by-step explanation:

it’s the right answer trust me

Color would be the same for both statue and stone buildings.

Let's, consider paint black as = x

and paint white as = y

If both the paints are mixed then paint z which is grey is formed.

Represented as,

x(black) + y(white) = z(grey)

Whereas, for the stone building double the amount of black and white colors are being used,

2x + 2y = 2z, coating of grey color would be also double.

Canceling 2 from both sides,

x + y = z

x(black) + y(white) = z(grey)

Therefore color would be the same for both statue and stone buildings.

8 units is the radius of the circle with a circumference of 16π.

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The circumference of a circle is expressed mathematically as;

C = 2 × π × r

Where r is radius and π is constant pi ( π = 3.14 )

Given the data in the question;

To find the radius of the circle, plug the given value into the circumference formula and solve for r.

C = 2 × π × r

16π = 2π × r

r = 16π / 2π

r = 16/2

Radius r = 8

Therefore, the radius of the circle is 8.

Answer:

Step-by-step explanation:

Considering the product and the sum of the roots of the quadratic function, the numeric value of the expressions are given as follows:

1. [tex]\beta x^2 + \alpha x^2 - \alpha\beta = \frac{1}{4}(x^2 - 1)[/tex]

2. [tex]\frac{\alpha}{\beta} + \frac{\beta}{\alpha} = -\frac{7}{4}[/tex]

A quadratic function is defined according to the following rule:

y = ax² + bx + c.

In which a and b are the coefficients of the equation.

Supposing that the equation has roots [tex]\alpha[/tex] and [tex]\beta[/tex], the product and the sum of the roots of the quadratic function are given as follows:

In this problem, the equation is:

4x² - x + 1.

Hence the coefficients are:

a = 4, b = -1, c = 1.

Then the product and the sum of the roots of the quadratic function are given as follows:

Then the numeric values for the expressions can be found as follows:

[tex]\beta x^2 + \alpha x^2 - \alpha\beta = x^2(\alpha + \beta) - \alpha\beta = \frac{1}{4}x^2 - \frac{1}{4} = \frac{1}{4}(x^2 - 1)[/tex]

For the second expression:

[tex]\frac{\alpha}{\beta} + \frac{\beta}{\alpha} = \frac{\alpha^2 + \beta^2}{\alpha\beta} = 4(\alpha^2 + \beta^2)[/tex]

The sum of the squares of the roots is:

[tex]\alpha^2 + \beta^2 = (\alpha + \beta)^2 - 2\alpha\beta[/tex]

Hence:

[tex]\alpha^2 + \beta^2 = \frac{1}{16} - \frac{1}{2} = -\frac{7}{16}[/tex]

Then:

[tex]\frac{\alpha}{\beta} + \frac{\beta}{\alpha} = -\frac{28}{16} = -\frac{7}{4}[/tex]

Answer:

m<A = 50°

Step-by-step explanation:

supplementary angles add up to 180°

m<B = 2x + 30

we don't know m<A, so we'll say the value of it is x

2x + 30 + x = 180°

3x + 30 = 180

3x = 150

x = 50

plug this value back in for x

m<B = 2(50) + 30 = 130

m<B = 130°

m<A = x = 50

m<A = 50°

to prove these are supplementary angles, 130 + 50 = 180

If you change the 2H₂ to 3H₂ molecules and balance the equation the equation will produce three molecules of water.

The provided chemical equation is,

2H₂ + O₂ → 2H₂O.

Changing 2H₂ with 3H₂

The chemical equation becomes,

3H₂ + O₂ → 2H₂O.

By doing this, the equation has become completely imbalanced,

So first we will balance it,

3H₂ +3/2O₂ → 3H₂O

Now, there will be 3 molecules of water formed.

As we observe the reaction more closely, we can see that the number of atoms of all the elements are equal on both the sides of the reaction.

The value of equation (x + y) will be 1.

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The equation are;

2y + 5x = 5   ... (i)

4y - x = 21    ... (ii)

Now, Solve both the equation and find the value of x and y as;

Multiply by 2 in equation (i) we get;

4y + 10x = 10

Subtract above equation by (ii);

4y + 10x - (4y - x) = 21 - 11

11x = 11

x = 1

And, 2y + 5x = 5

Substitute x = 1;

2y + 5x = 5

2y + 5 = 5

2y = 0

y = 0

So, x + y = 1 + 0 = 1

Step-by-step explanation:

They lost 14 yards, then lost and additional 7 more. You would simply add and make it a negative number due to the key word " lost ".

The equation would look like this: -14 + ( -7 ).

Another way to solve this equation is to multiply. ( + ) x ( - ) = -.

Your equation will the look this this: -14 - 7.

Now you just solve.

Thus, your answer should be - 21.

Hopes the helps!

Have a great day.

Answer: -21

Step-by-step explanation:

.A football team will lose an additional 7 yards if they lost 14 on their first play.

. Since the first play resulted in a loss of 14 yards, the integers that reflect the overall change in yards for the two plays are negative.

.In the second play, we score 14 points but lose 7 yards, which is a loss of 7 points.

.Negative 14 + Negative 7 = Negative 21, which is the overall change in yards.

. Hence, the answer would be -21 yards.

. -21 would be the correct integer that will represent the the total change in yards for the two plays.

Answer:

Farooq gets £8.75

Step-by-step explanation:

Let's represent the amounts obtained by David, Eva and Farooq as D, E and F to make things simpler. Let M be the total amount of money shared

D = 2.50 and represents 1/6 of the total amount of money(M)

So

M/6 = 2.50

Multiply both sides by 6 => M = 2.50 x 6 = £15

Eva gets 1/4th of this so E = 15 x 1/4 = £3.75

David gets £2.50

Together they get £2.50 + £3.75 = £6.25

The balance goes to Farook so F = 15 - 6.25 = £8.75

The differential equation for the amount of salt A(t) in the tank at the time (dA / dT) / (A / 100) = 0, A(0) = 30

It is Given that a large tank holds 400 gallons of water, in which 80 ponds of salt have been dissolved, given that pure water is pumped into the tank at a rate of 8 gallons/min. here we have to find the differential equation for the amount of salt in the tank at the time when the solution is well stirred. we have to multiply both 400 gallons of water and pumped water at the rate of 8 gallons/min.

dA / dT = Rin - Rout

Rin = 0

Rout = A(t) / 400 * 8

        = A / 50

So,

  dA / dt = Rin - Rout

dA / dt = 0 - A /50

After solving the differential equation we get

A(0) = 30

the constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.

We are given that 1 bulb out of every 9 bulbs is defective.

So, this means that if there is a total of 9 bulbs, then 1 bulb in it will be defective.

Let us assume:

Total bulbs = 9

So, this implies that:

Defective bulbs = 1

Constant of proportionality = Defective bulbs / Total bulbs.

Substituting the values in this, we get that:

Constant of proportionality = 1 / 9

Therefore, we get that, the constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.
