Tell whether the given value is a solution of the inequality

Answer:

D. 225 square units

Step-by-step explanation:

Multiply 2.5 by the scale factor of 6.

2.5 * 6 = 15

Then because it is a square, multiply 15*15

15 * 15 = 225

The answer is 225

Answer:

D

Step-by-step explanation:

The side length of the new square = 6 × 2.5 = 15 then its area

A = 15² = 225 units² → D

The two non negative real numbers with a sum of 64 that have the largest possible​ product are; 32 and 32.

Let the two numbers be x and y.

Thus, if their sum is 64, then we have;

x + y = 64

y = 64 - x

Their product will be;

P = xy

Putting (64 - x) for y in the product equation we have;

P = (64 - x)x

P = 64x - x²

Since the product is maximum, let us find the derivative;

P'(x) = 64 - 2x

At P'(x) = 0, we have;

64 - 2x = 0

2x = 64

x = 64/2

x = 32

Thus; y = 64 - 32

y = 32

The correct option is:(c.) f(a+h) = a² + h² + 2ah + 2a + 2h + 1

This can be obtained by substituting (a + h) into the function f(x):

f(a + h) = (a + h)² + 2(a + h) + 1

          = a² + 2ah + h² + 2a + 2h + 1

So, the correct expression for f(a + h) is a² + h² + 2ah + 2a + 2h + 1.

Step-by-step explanation:

Answer:

3216 grams of Zn

Step-by-step explanation:

It is not clear from the question if the ratio is based on the chemical formula, and is thus the ratio of atoms, or if it is based on mass (in g).  I'll assume it is based on the numbers of Zn and Cu atoms.

Let's convert the mass of copper, 494 grams, to moles of copper (representative of the number of atoms).  The molar mass of copper, Cu, is 63.55 grams/mole.  

Moles Cu =(494 grams)/(63.55 grams/mole) = 7.77 moles Cu

If zinc (Zn) is in a ratio of 19/3, we would have:

  (19 moles Zn/3 moles Cu)*(7.77 moles Cu) = 49.2 moles of Zn

The molar mass of zinc is 65.38 grams/mole

The mass of 49.2 moles of Zn is:

(49.2 moles Zn)(65.38 grams/mole) = 3216 grams of Zn

Answer:

10. y=the total amount of money

A) y=4m

B) y= 4(5.25)

y= $21

11. y= total amount of money

A) y= 40m + 35

B) y= 40(10) + 35

y= $435

Number 10:

You know five people, you and four friends, are contributing the same amount of money for food.  Lets say F = Food and M=Money.  Since they are contributing the same amount of money, it would be 5 * m, or 5m.  So, F would equal 5m.   F=5m.

Part B-  You would do the same expression, F=5m, but you would instead plug 5.25 in for m.  So, 5.25 times 5 would equal 26.25 dollars.

Number 11:

Part A- Let M equal months.  $40 times the number of months + 35 is the total cost, so 40m +35 is the expression.

Part B-  Since the total cost is 40 dollars times the number of months + $35, you would multiply 40 * 10, to get 400 dollars over 10 months.  Then you would add the $35 fee, so the answer would be $435.

Answer:

B. The length must decrease

Step-by-step explanation:

Given;

maximum volume of the tank, V = 24 ft³

maximum height of the tank, h = 4 ft

let the width of the tank = w

let the length of the tank = L

Volume of the tank is given by;

V = Lwh

L = V / (hw)

L = 24 / (4w)

L = 6/w

L is inversely proportional to w; an increase in w (width) will cause a decrease in L (length)

Therefore, If the designer increases the width of the fish tank, "The length must decrease"

Let's call the length of the bottom side of the triangular banner "b". When Alice reaches her arm up above the ground, the height of the banner changes from its original height of "h" to a new height of "h'". The area of the banner can be calculated using the formula:

A = (b * h') / 2

The new height "h'", can be calculated using the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the longest side (the hypotenuse).

In this case, the two shorter sides are the original height "h" and the difference between the length of Alice's arm and the original height, which we will call "d". The longest side is the distance between the two anchors, which we will call "a".

So:

h^2 + d^2 = a^2

We can solve for "d" using this equation:

d = sqrt(a^2 - h^2)

And then we can find "h'" using:

h' = h + d

So the area of the banner can be calculated as:

A = (b * (h + sqrt(a^2 - h^2))) / 2

The solution assumes that the banner is a right triangle, with one vertex at the top, one vertex at the bottom, and a straight side along the ground connecting the two bottom vertices.

The equation that represents h(x) is h(x) = (f(x))(g(x)).

To determine which equation represents h(x), we need to analyze the given table and understand the relationship between the functions f(x), g(x), and h(x).

Since h(x) represents the output values obtained by multiplying f(x) and g(x), we should look for values in the table where h(x) is the product of the corresponding values of f(x) and g(x).

Let's examine the table and compare the values:

x | f(x) | g(x) | h(x)

1 | 3 | 4 | 12

2 | 5 | 2 | 10

3 | 2 | 6 | 12

From the table, we can see that the values in the h(x) column are the products of the corresponding values in the f(x) and g(x) columns. Therefore, the equation that represents h(x) is h(x) = (f(x))(g(x)).

The area under one arch of the cycloid x = r(t − sin t), y = r(1 − cos t) for 0 ≤ t ≤ 2π is 4πr².

To find the area under one arch of the cycloid x = r(t − sin t), y = r(1 − cos t) for 0 ≤ t ≤ 2π, we can use the formula for finding the area under a curve:

A = ∫[a,b] f(x) dx

In this case, we need to find the integral of y with respect to x:

A = ∫[0,2π] y dx

We can solve for y in terms of t by substituting x = r(t − sin t) into the equation for y:

y = r(1 − cos t)

dx = r(1 − cos t) dt

Substituting these into the formula for the area, we get:

A = ∫[0,2π] r(1 − cos t)(r(1 − cos t) dt)

Simplifying, we get:

A = r² ∫[0,2π] (1 − cos t)² dt

Using the trig identity (1 − cos 2t) = 2 sin² t, we can simplify the integrand:

A = r² ∫[0,2π] (1 − cos t)² dt

= r² ∫[0,2π] (1 − 2cos t + cos² t) dt

= r² ∫[0,2π] (1 − 2cos t + (1 − sin² t)) dt

= r² ∫[0,2π] 2(1 − cos t) dt

= r² [2t − 2sin t] from 0 to 2π

= 4πr²

Therefore, the area under one arch of the cycloid x = r(t − sin t), y = r(1 − cos t) for 0 ≤ t ≤ 2π is 4πr².
