A student drops a rock over the edge of the well and hears it splash into water after 3 seconds. Write a function in the form h(t) = − 16t2 + v0 t + h0 to determine the height of the rock above the bottom of the well t seconds after the student drops the rock. What is the distance from the surface of the water to the bottom of the well?

Answer:

50.24 ft^2

Step-by-step explanation:

The radius of the circle in which the lawn sprinkler sprays water is 4 feet.

The formula to find the area of a circle is [tex]\pi r^2[/tex], where r = radius and π, in this case, is 3.14.

Therefore, the answer is 50.24 ft².

Answer:  4000 cm^3

Step-by-step explanation:

The volume of a rectangular prism is the length*width*height.

We can plug in the values given:

Volume = 20 cm * 20 cm * 10 cm

Volume = 4000 cm^3

Answer:

The simple answer, "Yes"

Answer:

Point slope form of the equations:

y = -3x + 8

y = 2x - 2

Solution to the system of equations:

(x, y) ==> (2, 4)

Step-by-step explanation:

6x + 2y = 16

2x - y = 2

6x + 2y = 16

2(2x - y = 2)  ==> 4x - 2y = 4

6x + 2y = 16

4x - 2y = 4

10x = 20

/10     /10

x = 2

Now, we solve for y:

6x + 2y = 16

6(2) + 2y = 16

12 + 2y = 16

-12         -12

2y = 4

/2   /2

y = 2

(x, y) ==> (2, 2)

Point-slope forms:

6x + 2y = 16

-6x          -6x

2y = -6x + 16

/2        /2

y = -3x + 8

2x - y = 2

-2x      -2x

-1y = -2x + 2

/-1       -1

y = 2x - 2

Using known formulas for cylinders, we will get:

We know that the pot has a diameter of 10cm and a height of 21 cm, and the hole must be 4 cm wider (so the diameter is 14cm) and 5 cm deeper (so the height is 26cm).

i) The volume of a cylinder of radius r and height H is given by:

V = pi*r^2*H

Where pi = 3.14, and the radius is half the diameter, so we have:

r = 14cm/2 = 7cm.

Then the volume is:

V = 3.14*(7cm)^2*26cm = 4,000.36 cm^3

ii) To fill a volume of 4,000.36 cm^3, you need 4,000.36 cm^3 of water.

iii) The curve surface of a cylinder is given by:

S = 2*pi*r*H

Remember that:

r = 7cm

H = 26cm.

Replacing that we get:

S = 2*3.14*7cm*26cm = 1,142.96 cm^2

So se must paint an area of 1,142.96 cm^2.

Using the Central Limit Theorem, considering a normally distributed population with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution is normal, with mean [tex]\mu[/tex] and standard deviation [tex]0.5\sigma[/tex].

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

Hence, considering a normally distributed population with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], and with the sample size of n = 4, the mean remains the same while the standard deviation is given by:

[tex]s = \frac{\sigma}{\sqrt{4}} = 0.5\sigma[/tex]

$33.91

Step-by-step explanation: Take 35% and change it to .35 now multiply 96.88 by .35 and you will get 33.908 round up to 33.91

Answer:

33.908

Step-by-step explanation:

To find the percentage of a certain number, you need to convert the percentage into its decimal form (0.35) and multiply it by the certain number. Then you'll have your answer!

0.35*96.88=33.908

33.908 is 35% of 96.88

Here's another example! Let's say you want to find 45% of.... 78!

45% is 45/100. The first step is to convert 45% into its decimal form. (45/100=0.45)

Then you multiply the decimal by the number you want to find the percentage of!

0.45*78=35.1

35.1 is 45% of 78!

Answer: 33,800

Step-by-step explanation: 10,400 x 3.25 = 33,800

Answer:

14,200 people are now in the town

Step-by-step explanation:

First, find 3.25% of 10,400.

3.25% of 10,400

3.25 × 10,400 = 3,800

Then, add that to 10,400 to get 14,200.

Answer:

Step-by-step explanation:

small=s,    s=3.99

large=l,       l=19.20

10s+8l=192.20

20s+l=99

we can see that in the second equation, 20s+l=99

l=99-20s

lets replace l in the first equation

10s+8(99-20s)=192.20

10s+792-160s=192.20

-150s=-792+192.20

150s=599.80

s=3.99

l=99-20(3.99)=99-79.80=19.20

Answer:

19

Step-by-step explanation:

You can set up a system of equations.

x=small, and y = large.

10x+8y=$192

20x+1y=$99

you can multiply the first equation by -2 to get rid of x:

20x+1y=$99

-20x-16y=-$384

when you combine them, you get:

-15y=$-285

you can divide by -15 and you get:

y=19, so 1 large equals $19

An ounce unit will best represent each scenario.

The average weight of an elephant is around 3000-4000 kg.

The average weight of a mouse = 15-20 grams

The average weight of a puppy = 25-30kg

It is given that

Weight of the elephant = [tex]1.5 * 10^5[/tex] units ≈150000 units

Weight of the mouse = [tex]6.3*10^2[/tex] units ≈630 units

Weight of the puppy = [tex]1.2*10^3[/tex] units ≈1200 units

1 ounce = 0.0253495 kg

150000 ounces = 3800kg, near to actual value

630 ounces = 16kg, near to actual value

1200 ounces = 30kg, near to actual value

Therefore, an ounce unit will best represent each scenario.

y = mx + c

m is the gradient

c is the y intercept

m is

m is rise/run

the line rises from 3 to 10

so rise is 7

the line runs from 0 to 3.5

so run is 3.5

m = 7/3.5

m = 2

c is

y-intercept is where the line is equal to x=0

that point is
