Answer:

y = 2

Step-by-step explanation:

Given that y varies inversely as the square of x then the equation relating them is

y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of variation

To find k use the condition y = 2 when x = 4

k = yx² = 2 × 4² = 2 × 16 = 32, thus

y = [tex]\frac{32}{x^2}[/tex] ← equation of variation

When x = 4, then

y = [tex]\frac{32}{4^2}[/tex] = [tex]\frac{32}{16}[/tex] = 2

Answer: Radius

Step-by-step explanation: The radius of a circle is a segment that joins the center of the circle to a point on the circle.

The minute hand on a clock would start in the center and go outwards towards a certain number. However, the minute hand would not go the full length across the clock so it's not the diameter.

The circumference of a circle which is another way of saying the perimeter of the circle is the distance around the circle so it would not be the circumference.

This means that the minute hand would represent the radius of a clock.

The 5 inch length of the minute hand on the clock is actually a radius, not a diameter or circumference. This radius is the distance from the center of the clock face to the tip of the minute hand. The diameter, which would be twice the length of the radius, would be 10 inches, and the circumference of the circle formed by the minute hand's movement would be approximately 31.4 inches.

In this case, the 5 inches refers to the radius of the circle that is created by the minute hand of the clock as it moves around the clock face. This radius is the distance from the center of the clock face to the tip of the minute hand. In general, in any circular motion, the length of the revolving component, like a clock hand, from the center to its tip is called the radius of the circle.

The diameter is simply twice the radius, and in this case if the radius is 5 inches, the diameter would be 10 inches. The circumference of a circle is calculated by the formula 2πr (2 times the value of pi times the radius), hence, in this instance, it would be 10π inches or approximately 31.4 inches.

{12, 4, -6}

Step-by-step explanation:

The relation is given by the equation as 12x + 6y = 24 ........... (1)

Now, the domain of this function is {-4, 0, 5}

We have to find the range of this function corresponding to the given domain.

Now, for x = - 4,  

12(-4) + 6y = 24 {From equation (1)}

⇒ 6y = 72

⇒ y = 12

Now, for x = 0,  

12(0) + 6y = 24 {From equation (1)}

⇒ 6y = 24

⇒ y = 4  

Now, for x = 5,  

12(5) + 6y = 24 {From equation (1)}

⇒ 6y = -36

⇒ y = -6

Hence, the range for the relation is {12, 4, -6} (Answer)

Answer:

6 large, 12 medium and 18 small

Step-by-step explanation:

Lets call small pizzas s, medium pizzas m and large pizzas l, with its respective prices $10, $15 and $40.

As they sell as many small as medium and large combined we can say that:

s = m + l [eq 1]

Also, as the number of medium is twice the larges we can say that:

m = 2l [eq 2]

Finally, as the get $600 we know that every amount sold multiplied by its price, and summing all together must bring $600:

10s + 15m + 40l = 600 [eq 3]

Lets replace s by its value in eq 1:

10s + 15m + 40l = 10 (m+l) 15m + 40l = 10m +10l + 15m + 40l = 600

25m + 50l = 600

Now we can replace m by its value in eq 2:

25m + 50l = 25 (2l) + 50 l = 50l + 50l = 100l = 600

100l = 600

Now divide both sides by 100:

l = 6

So, 6 large pizzas were sold.

Replace l=6 in eq 2:

m = 6*2

m = 12

12 medium pizzas were sold.

Finally, replace l=6 and m=12 in eq 1

s = m + l = 12 + 6 = 18

And 18 small pizzas were sold.

Lets verify our results in eq. 3:

10*(18) + 15*(12) + 40*(6) = 600

180 + 180 + 240 = 600

360 + 240 = 600 ---> Verified!

Option 3

The solution for given expression is [tex]\frac{(x - 4)(x - 4)}{(x + 3)(x + 1)}[/tex]

Given that we have to divide,

[tex]\frac{x^2 -16}{x^2 + 5x + 6} \div \frac{x^2 + 5x + 4}{x^2 -2x - 8}[/tex]   ---- (A)

Let us first factorize each term and then solve the sum

Using [tex]a^2 - b^2 = (a + b)(a - b)[/tex]

[tex]x^2 -16 = x^2 - 4^2 = (x + 4)(x -4)[/tex]  ----- (1)

[tex]x^2 + 5x + 6 = (x + 2)(x + 3)[/tex]   ----- (2)

[tex]x^2 + 5x + 4 = (x+1)(x + 4)[/tex]   ---- (3)

[tex]x^2 -2x - 8 = (x-4)(x + 2)[/tex]   ---- (4)

Now substituting (1), (2), (3), (4) in (A) we get,

[tex]\frac{(x + 4)(x -4)}{(x +2)(x +3)} \div \frac{(x+1)(x+4)}{(x-4)(x +2)}[/tex]

To do division with fractions, we turn the second fraction upside down and change the division symbol to a multiplication symbol at the same time. Then we treat this as a multiplication problem, by multiplying the numerators and the denominators separately.

[tex]\frac{(x + 4)(x -4)}{(x +2)(x +3)} \times \frac{(x - 4)(x + 2)}{(x + 1)(x + 4)}[/tex]

On cancelling terms we get,

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

Thus option 3 is correct

First we're going to change the 3 1/4 into an improper fraction.

3 1/4 is the same as 13/4

When dividing fractions, it's the same thing as multiplying by the reciprocal.

What this means is we're going to flip the second fraction.

So the original problem is this:

13/4 divided by 3/1

It now looks like this:

13/4 multiplied by 1/3

Then, simply multiply the top numbers together and then multiply the bottom numbers together.

13*1=13

4*3=12

your answer is 13/12

D) 12 cm is the right answer

Step-by-step explanation:

Given

[tex]Radius\ of\ sphere = r_s = 6\ cm\\Height\ of\ cone = h = 6 cm\\[/tex]

As the volumes of cone and sphere are same

[tex]V_s = V_c\\\frac{4\pi {r_s}^3}{3} = \frac{\pi {r_c}^2h}{3}[/tex]

Putting the known values

[tex]\frac{4\pi {6}^3}{3} = \frac{\pi {r_c}^2*(6)}{3}[/tex]

Dividing both sides by pi

[tex]\frac{4\pi {(6)}^3}{3\pi } = \frac{\pi {r_c}^2*(6)}{3\pi }\\\frac{4*{(6)}^3}{3} = \frac{{r_c}^2*(6)}{3}[/tex]

Multiplying both sides by 3

[tex]4*(6)^3 = 6{r_c}^2\\{r_c}^2 = \frac{4*(6)^3}{6}\\{r_c}^2 = 4 * 6^2\\{r_c}^2 = 144[/tex]

Answer:

Part a) [tex]V(h)=6.25\pi h\ in^3[/tex]

Part b) [tex]V(3)=18.75\pi\ in^3[/tex]  (see the explanation)

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

[tex]V=Bh[/tex]

where

B is the area of the base of cylinder

h is the height of the cylinder

we have that

[tex]B=\pi r^{2}[/tex]

Part a) Write the function, V(h), that represents the volume of the cylinder

we have

[tex]r=5/2=2.5\ in[/tex] ----> the radius is half the diameter

substitute

[tex]B=\pi (2.5)^{2}[/tex]

[tex]B=6.25\pi\ in^2[/tex]

The volume is

[tex]V(h)=6.25\pi h\ in^3[/tex]

Part b) Find V(3) and tell what it represents

V(3) represent the volume of the cylinder with a height of 3 inches

so

For h=3 in

substitute

[tex]V(3)=6.25\pi(3)\ in^3[/tex]

[tex]V(3)=18.75\pi\ in^3[/tex]

Final answer:

The function for the volume of the cylinder with diameter 5 inches is V(h) = π * (2.5 inches)² * h. To find V(3), we calculate the volume with height 3 inches, which represents the physical volume of the cylinder at that height.

Explanation:

To find the volume of the cylinder, V(h), we must use the formula V = πr²h, where r is the radius of the base, and h is the height of the cylinder.

Part A: Given that the diameter is 5 inches, the radius is half of the diameter, so r = 5 / 2 = 2.5 inches. Thus, the function representing the volume is V(h) = π * (2.5 inches)² * h.

Part B: To find V(3), we substitute h with 3 inches into the function: V(3) = π * (2.5 inches)² * 3 inches. This gives us the volume of the cylinder when the height is 3 inches.

Answer:

Both fireworks  will explode after 1 seconds after firework b launches.

Step-by-step explanation:

Given:

Speed of fire work A= 300 ft/s

Speed of Firework B=240 ft/s

Time before which fire work b is launched =0.25s

To Find:

How many seconds after firework b launches will both fireworks explode=?

Solution:

Let t be the time(seconds) after which both the fireworks explode.

By the time the firework a has been launched, Firework B has been launch 0.25 s, So we can treat them as two separate equation

Firework A= 330(t)

Firework B=240(t)+240(0.25)

Since we need to know the same time after which they explode, we can equate both the equations

330(t) = 240(t)+240(0.25)

300(t)= 240(t)+60

300(t)-240(t)= 60

60(t)=60

[tex]t=\frac{60}{60}[/tex]

t=1

Final answer:

By setting the distance traveled by both fireworks equal, we find that both Firework A and B will explode 1.25 seconds after Firework B is launched.

Explanation:

To solve the problem of when both fireworks will explode, we can use the constant speed equation distance = speed × time. Firework A travels at 300 ft/s, and Firework B travels at 240 ft/s. Firework B is given a 0.25s head start. We need to find the time when they have traveled the same distance.

Let's call the time after Firework B launches when both explode as t. Since Firework A launches 0.25s after B, it will have traveled for t - 0.25s when they explode together. The equations for the distances traveled by both fireworks until that point will be:

Setting these distances equal to each other:

300 (t - 0.25) = 240 t

Solving for t:

300t - 75 = 240t

60t = 75

t = 1.25s

Therefore, both fireworks will explode 1.25 seconds after Firework B launches.
