Answer:

  1.5 seconds

Step-by-step explanation:

The height equation is supposed to be ...

  h(t) = -16t^2 +22t +3

We want to find the positive value of t where h(t) = 0.

  0 = -16t^2 +24t -2t +3 . . . . facilitate factoring

  0 = -8t(2t -3) -1(2t -3) . . . . . factor by pairs

  0 = -(8t +1)(2t -3) . . . . . . . .  complete the factoring

The solutions to this are ...

  t = -1/8, 3/2

The ball will reach the ground in 1.5 seconds.

Answer:

72

explanation:

Just took the test

Given that the sum of 3 consecutive even integers is 36, we can define the variables to be:

And we can set up the equation as:

[tex]\sf {N + (N + 2) + (N + 4) = 36} \\ \sf{\longrightarrow 3N + 6 = 36} \\ \sf{\longrightarrow 3N = 30} \\ \sf{\longrightarrow N = 10}[/tex]

The first even number which we assumed was N, which is equal to 10.

And hence the answer will be

[tex]\leadsto \underline{\boxed{\sf{\pink{\quad10\quad}}}}[/tex]

Verification:

3 consecutive even no.s :

Their sum = 10 + 12 + 14 = 36

Hence, N = 10 is the solution of the question.

Answer:

3 : 2

Step-by-step explanation:

Number of students in the class = 15

Number of boys in class  = 9

To describe ratio;

  We know that the number girls in the class will be

          15 - 9 = 6 students.    

Simply in this class, the ratio of boys to girls:

            9 : 6  = 3 : 2

In the class, we have 3 boys to 2 girls.

x/r + x/w + x/t = 1

x (1/r + 1/w + 1/t) = 1

x = 1 / (1/r + 1/w + 1/t)

To make the solution a bit cleaner, multiply through the numerator and denominator by the LCM of each fraction's denominator, rwt :

x = 1 / (1/r + 1/w + 1/t) • rwt / rwt

x = rwt / (rwt/r + rwt/w + rwt/t)

x = rwt / (wt + rt + rw)

Answer:

[tex]\frac{dh}{dt}\approx0.08622\text{ ft/min}[/tex]

Step-by-step explanation:

We know that the conical water tank has a radius of 13 feet and is 21 feet high.

We also know that water is flowing into the tank at a rate of 30ft³/min. In other words, our derivative of the volume with respect to time t is:

[tex]\frac{dV}{dt}=\frac{30\text{ ft}^3}{\text{min}}[/tex]

We want to find how fast the depth of the water is increasing when the water is 17 feet deep. So, we want to find dh/dt.

First, remember that the volume for a cone is given by the formula:

[tex]V=\frac{1}{3}\pi r^2h[/tex]

We want to find dh/dt. So, let's take the derivative of both sides with respect to the time t. However, first, let's put the equation in terms of h.

We can see that we have two similar triangles. So, we can write the following proportion:

[tex]\frac{r}{h}=\frac{13}{21}[/tex]

Multiply both sides by h:

[tex]r=\frac{13}{21}h[/tex]

So, let's substitute this in r:

[tex]V=\frac{1}{3}\pi (\frac{13}{21}h)^2h[/tex]

Square:

[tex]V=\frac{1}{3}\pi (\frac{169}{441}h^2)h[/tex]

Simplify:

[tex]V=\frac{169}{1323}\pi h^3[/tex]

Now, let's take the derivative of both sides with respect to t:

[tex]\frac{d}{dt}[V]=\frac{d}{dt}[\frac{169}{1323}\pi h^3}][/tex]

Simplify:

[tex]\frac{dV}{dt}=\frac{169}{1323}\pi \frac{d}{dt}[h^3}][/tex]

Differentiate implicitly. This yields:

[tex]\frac{dV}{dt}=\frac{169}{1323}\pi (3h^2)\frac{dh}{dt}[/tex]

We want to find dh/dt when the water is 17 feet deep. So, let's substitute 17 for h. Also, let's substitute 30 for dV/dt. This yields:

[tex]30=\frac{169}{1323}\pi (3(17)^2)\frac{dh}{dt}[/tex]

Evaluate:

[tex]30=\frac{146523}{1323}\pi( \frac{dh}{dt})[/tex]

Multiply both sides by 1323:

[tex]39690=146523\pi\frac{dh}{dt}[/tex]

Solve for dh/dt:

[tex]\frac{dh}{dt}=\frac{39690}{146523}\pi[/tex]

Use a calculator. So:

[tex]\frac{dh}{dt}\approx0.08622\text{ ft/min}[/tex]

The water is rising at a rate of approximately 0.086 feet per minute.

And we're done!

Answer:

-3 is the integer

4 would be greater than -3

Answer:

#2 and #4

Step-by-step explanation:

area is length times width, so to find your answer you must multiply all the lengths and widths given in the table. when you multiply 3x+6 and 4 (for #2) and simplify, you get 12x+24. when you multiply 2x+4 and 6 (for #4) and simplify, you get the same thing: 12x+24.

Answer:

y = -2x+8

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

    = ( -4-4)/(6-2)

    = -8/4

   = -2

The slope is -2

We can use the slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = -2x +b

Using the point ( 2,4)

4 = -2(2) +b

4 = -4+b

Add 4 to each side

4+4 = -4+4+b

8 = b

y = -2x+8

Step-by-step explanation:

7/8 cups of sauce are needed to make 1 pizza.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Domino's can make 4 pizzas using 3 1/2 cups of sauce.

Now, for 1 pizza he needed

= (3 1/2) /4

= (7/2)/ 4

= 7/2 x 1/4

= 7/8 cups of sauce.

Hence, 7/8 cups of sauce needed.

Answer:B and E

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

From the figure attached,

'b' and 'c' are the parallel lines and line 'a' is a transversal line intersecting parallel lines at the points respectively.

Line 'a' is perpendicular to line 'b'.

Angle between lines 'a' and 'b' is 90°.

Therefore, m(∠X) + 90° = 180° [Linear pair of angles]

m(∠X) = 90°

Since, angle X and angle having measure [5(x + 7) + 15]° are the corresponding angles,

m(∠X) = [5(x + 7) + 15]°

90° = [5(x + 7) + 15]°

5(x + 7) = 90 - 15

5(x + 7) = 75

x + 7 = 15

x = 8

Therefore, x = 8 will be the answer.
