Answer 1

Answer: You are incorrect, the slope is correct, but the actual y-intercept is 205 ft.

Then the equation is:

y = (-15 ft/min)*x + 205 ft

Step-by-step explanation:

Ok, let's solve this.

We know that water is drained from a reservoir, let's assume that we can model this situation with a linear relation:

y = a*x + b

Where x is time, y is the height of the water in the reservoir, a is the slope (in this case represents how much changes the height of the water in the reservoir in one unit of time) and b is the initial height of the water in the reservoir.

We know that for a line that passes through the points (x₁, y₁) and (x₂, y₂) the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

For this particular case we know that after 2 minutes the height of the water is 175 ft, then we have the point (2 min, 175 ft)

and after 5 minutes (so 7 minutes in total), the height of the water is 100ft, then: (7 ft, 100ft)

Then the slope of this:

a = (100 ft - 175 ft)/(7 min - 2 min) = (-75ft/5min) = - 15 ft/min

Then our line is something like:

y = (-15ft/min)*x + b

To find the value of b, we can use the fact that when x = 2 min, y = 175 ft

So if we replace these two values in the equation we get:

175ft = (-15 ft/min)*2 min + b

175 ft = -30 ft + b

175 ft + 30 ft = b                  

(here is your problem, it seems like you subtracted instead of adding in this part)

205 ft = b

Then the equation is:

y = (-15 ft/min)*x + 205 ft

So you are incorrect (but only for a little bit), you computed wrong the y-intercept.

Q1 2. Q2 3.

Step-by-step explanation:

to solve a system of equations, you would usually have to use either elimination or substitution. however, in both of these problems, Y is given directly so that's unnecessary

for these, all you have to do is plug in y and then solve for x, where x is then the first number in the ordered pair and y is the second number.

Q1 48/-6 = -8, so the answer is (-6,-8)

Q2 10/2=5, so the answer is (5, -1)

Answers

Answer:

x = 7

Step-by-step explanation:

Given

3x - 5 = 16 ( add 5 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Answer: X= 7

Explanation:
(you need to get x by its self)

Step 1- add the (-5) over to the 16

Because to get rid of a negative or minus sign you need to do the opposite which is addition.

You’ll get: 3x=21

Step 2- divide the 3 off from 21
Because the ‘3x’ is acting as multiplication, and the opposite of multiplication is division

You’ll get: X=21/3
Which is X=7

Answers

Answer:

a) The ratio of height is 2:15

b) The ratio of surface area is 4:225

c) The ratio of volume is 8:3375

Step-by-step explanation:

The scale factor of model to original is 2 :15

Please remember the concept, when scale factor is a:b

Then ratio of sides would be same a:b

The ratio of surface area is [tex]a^{2} :b^{2}[/tex]

The volume is [tex]a^{3} :b^{3}[/tex]

According to the concept,

The ratio of height is 2:15

The ratio of surface area is [tex]2^{2} :15^{2}[/tex] =4:225

The ratio of volume is [tex]2^{3} :15^{3}[/tex] =8 :3375.

Three of the four vertices of a rectangle are located at (4, 2), (7, 2) and (4, 8). a. What are the coordinates of the missing vertex? ( , ) b. Find the area and perimeter of the rectangle. Area = square units Perimeter = units

Answers

Answer:

a) The coordinates of the missing vertex = (7, 8)

b) Area = 18 square units

   Perimeter = 18 units

Step-by-step explanation:

a) We know three of the four vertices:

A: (4, 2)           C ______ D(?)

B: (7, 2)               |             |

C: (4, 8)           A |______| B  

To find the coordinates of the missing vertex we need to calculate the distance in the x-direction from point A to point B:

[tex] B_{x} - A_{x} = 7 - 4 = 3 [/tex]                    

Hence, the distance of point D from point C in the x-direction is:

[tex] D_{x} = C_{x} + 3 = 4 + 3 = 7 [/tex]

Now, to find the coordinate in "y" we need to calculate the distance in the y-direction between point C and point A:

[tex] C_{y} - A_{y} = 8 - 2 = 6 [/tex]  

Then, the distance of point D from point B in the y-direction is:

[tex] D_{y} = B_{y} + 6 = 2 + 6 = 8 [/tex]

Therefore, the coordinates of the missing vertex (point D) are:

[tex] D = (D_{x}, D_{y}) = (7, 8) [/tex]    

b) The area of the rectangle is:

[tex] a = (B_{x} - A_{x})*(C_{y} - A_{y}) = 3*6 = 18 units^{2} [/tex]

The perimeter is given by:

[tex] p = 2*(3 + 6) = 18 units [/tex]

I hope it helps you!          

The volume of a sphere can be determined by the formula V = 4/3 πr^3, where r is the radius. What is the volume of a sphere with radius 3/2x^3y^–2 in terms of x and y?

Answers

Answer:

[tex]V = \frac{99}{7} x^{9}y^{-6}[/tex]

Step-by-step explanation:

Given

[tex]V = \frac{4}{3}\pi r^3[/tex]

Required

Find V when

[tex]r = \frac{3}{2}x^3y^{-2[/tex]

Substitute [tex]\frac{3}{2}x^3y^{-2[/tex] for r in [tex]V = \frac{4}{3}\pi r^3[/tex]

[tex]V = \frac{4}{3}\pi * (\frac{3}{2}x^3y^{-2})^3[/tex]

Open bracket

[tex]V = \frac{4}{3}\pi * \frac{3}{2}^3 * x^{3*3}y^{-2*3}[/tex]

[tex]V = \frac{4}{3}\pi * \frac{27}{8} * x^{9}y^{-6}[/tex]

Simplify the fractions

[tex]V = \pi * \frac{9}{2} * x^{9}y^{-6}[/tex]

Let

[tex]\pi = \frac{22}{7}[/tex]

So:

[tex]V = \frac{22}{7} * \frac{9}{2} * x^{9}y^{-6}[/tex]

[tex]V = \frac{11}{7} * \frac{9}{1} * x^{9}y^{-6}[/tex]

[tex]V = \frac{99}{7} * x^{9}y^{-6}[/tex]

[tex]V = \frac{99}{7} x^{9}y^{-6}[/tex]
