it is 72mm because there are 6 cubes and they each are 12mm so you do 6*12 witch is 72

Answer:

h(t) = -16t² + 200

distance = 56 ft

Step-by-step explanation:

First of all, we know that the initial velocity (v0) of the rock is 0 ft/s because the rock was dropped. We also know that the initial height of the rock is 200 ft because it was dropped at the top of the well which is 200 ft high. Plugging this information into our quadratic function we get h(t) = -16t² + 200.

Now we need to find the distance from the surface of the water to the bottom of the well. This distance is equal to the height of the rock at time equals 3 seconds. Therefore, all we need to do is find h(3) = -16(3)² + 200 = 56 ft.

The diagram illustrates congruent and complementary angles

The congruent statement [tex]\angle C \cong \angle P[/tex] is true

The given parameters are:

Angles C and O are complementary angles

Angles P and M are complementary angles

[tex]\angle O \cong \angle M[/tex]

The statement [tex]\angle O \cong \angle M[/tex] means that, angles O and M are congruent angles.

From the figure, we have:

[tex]\angle C = 90 - \angle O[/tex]

Also, we have:

[tex]\angle P = 90 - \angle M[/tex]

Recall that: [tex]\angle O \cong \angle M[/tex]

So, we have:

[tex]\angle P = 90 - \angle O[/tex]

By comparison, we have:

[tex]\angle C \cong \angle P = 90 - \angle O[/tex]

Hence, the statement [tex]\angle C \cong \angle P[/tex] has been proven

Answer:

The square root is 2357.0224861

Answer:

x= 6.324555320

Step-by-step explanation:

X^2=40

1. Square root both sides

2. You should be left with x=6.32....

Solution: √40 = x

So basically, you have to find x, which is raised to the power of two. To find that, we'll have to square root 40 because square rooting a number is the opposite of squaring a number

So 40 squared = 6.32455532034

A really long number...

Now, let's check our answer

6.32455532034^2 = 40

So therefore, x = 6.32455532034

Hope this helped!!

Answer:

Step-by-step explanation:

Multiply the top equation by 3.

3*(x - y)/3 = 0.5 * 3

(x - y) = 1.5

There is no single solution that satisfies this system. There infinitely many values for x and y that will work. The only restriction is that x - y = 1,5

So if you make y = 3

x - 3 = 1.5                   Add 3 to both results

x - 3 + 3 = 1.5 + 3       Combine

x = 4.5

Infinitely many solutions exist.

Answer:

y=900x-1700

Step-by-step explanation:

(sorry if the explanation is long)

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

First, let's find what m is, the slope of the line...

The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.

For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:

So what we need now are the two points you gave that the line passes through. Let's call the first point you gave, (2,100), point #1, so the x and y numbers given will be called x1 and y1. Or, x1=2 and y1=100.

Also, let's call the second point you gave, (3,1000), point #2, so the x and y numbers here will be called x2 and y2. Or, x2=3 and y2=1000.

Now, just plug the numbers into the formula for m above, like this:

m=

1000 - 100

3 - 2

or...

m=

900

1

or...

m=900

So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:

y=900x+b

Now, what about b, the y-intercept?

To find b, think about what your (x,y) points mean:

(2,100). When x of the line is 2, y of the line must be 100.

(3,1000). When x of the line is 3, y of the line must be 1000.

Because you said the line passes through each one of these two points, right?

Now, look at our line's equation so far: y=900x+b. b is what we want, the 900 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the two points (2,100) and (3,1000).

So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!.

You can use either (x,y) point you want..the answer will be the same:

(2,100). y=mx+b or 100=900 × 2+b, or solving for b: b=100-(900)(2). b=-1700.

(3,1000). y=mx+b or 1000=900 × 3+b, or solving for b: b=1000-(900)(3). b=-1700.

See! In both cases we got the same value for b. And this completes our problem.

The equation of the line that passes through the points

(2,100) and (3,1000)

is

y=900x-1700

Step-by-step explanation:

this is correct

Answer:

[tex]y=3^x[/tex]

Step-by-step explanation:

exponential function : y = a(b)^x

where a = y intercept and b = factor ( number you are multiplying by )

according the the graph the y intercept is a 1 so a = 1

we now have y = 1(b)^x

to find the factor you plug in one of the ordered pairs into y = 1(b)^x

the ordered pair you use will not effect the outcome, i have chose (2,9)

y = 1(b)^x

(x,y) = (2,9) so x = 2 and y = 9

9 = 1(b)^2

divide both sides by 1

9 = (b)^2

take the square root of both sides

3 = b

the final equation is y = 1(3)^x or just y = 3^x

Answer:

 $22.88

Step-by-step explanation:

The total bill is the subtotal plus tax. The tax is computed by multiplying the tax rate by the subtotal, which is the total of all items being billed.

  subtotal = $5.25 +12.75 +2.99 = 20.99

  tax = $20.99 × 0.09 = $1.89

The total bill is ...

  subtotal + tax = $20.99 +1.89 = $22.88

Answer:

y = 8x - 5

Step-by-step explanation:

Given:

To find:

How to find:

The slope is always known as "constant of variation" or "rate of change", but it's basically the increase of both y and x axes in simple terms. The decrease or increase in two points together and then found with the formula of rise/run (increase and decrease) (horizontal line/vertical line).

The y-intercept is always on the y-axis and is the beginning of what is learned in pre-algebra as a "story" which helps students practice finding the slope which again, is the change with "per" or "each".

Make sure to use the formula:

y = mx + b

Now we insert.

y = 8x <---------- slope

y = 8x - 5 <------ y-intercept and completed slope-intercept equation.

The reason it has a negative is because it started out as a negative y-intercept and is increasing by 8 through ordered pairs.

Answer:

y = 8x - 5

Step-by-step explanation:

because if its has a slope of 8 then m is 8

if the y intercept is -5 the b is -5

y = mx + b

y = 8x -5
