Whats a line passing<br> through the<br> points (0, 0) and<br> (5,-7)?
Ipatiy [6.2K]

Answer:

y = -7/5x

Step-by-step explanation:

First, we need to use the two points to find the slope.

m = y₁ - y₂ / x₁ - x₂

m = -7 - 0 / 5 - 0

m = -7/5

Now we know that the slope is -7/5. Now we'll substitute the information we've gathered into the point-slope form equation to get an equation.

y - y₁ = m(x - x₁)

y - (-7) = -7/5(x - 5)

y + 7 = -7/5x + 7

y = -7/5x

Therefore, the equation of the line is y = -7/5x.

Each hemisphere of isabels globe has a volume of 60,750 pie cm^3. What is the radius of her globe
zaharov [31]

Answer:

45cm

Step-by-step explanation:

Volume of a sphere = 4/3πr³

Volume of an hemisphere = 1/2 of volume of a sphere

Volume of hemisphere = 1/2{4/3πr³}

Volume of hemisphere = 2/3πr³

Given

Volume of the hemisphere = 60,750πcm³

60,750π = 2/3πr³

π cancels out

60,750 = 2/3r³

Multiply both sides by 3

2r³ = 60,750×3

2r³=182,250

Divide both sides by 2

r³ = 91,125

Find the ∛ of 91,125 to eliminate the cube on r

r = ∛91,125

r = 45cm

The first difference of a sequence is 1, 4, 7, 10, 13…
Rama09 [41]

Answer:

1) {4, 5, 9, 16, 26, 39}

2) {3, 4, 8, 15, 25, 38}

3) {3, 4, 8, 15, 25, 38}

Step-by-step explanation:

Hi!

Let's call the sequence {x₁, x₂, x₃, etc}

The information you have is the difference between to consecutive terms:

x_2-x_1= 1\\x_3-x_2= 4\\x_4-x_3= 7\\x_4-x_5= 10\\x_6-x_5= 13

1) Data: x₁=4, then to get x₂ you sum 1, and get x₂=5. Then to get x₃ you sum 4, and get x₃=9, and so on. Result:  {4, 5, 9, 16, 26, 39}

2) Data: x₁ + x₂ = 7. You know that x₂ = x₁ + 1. Then:

x_1+x_2 = x_1 +x_1 +1= 2x_1+1=7\\x_1=3\\x_2= x_1 +1 = 3+1=4

If you continue the same process as in 1), you get {3, 4, 8, 15, 25, 38}

3) Data: x₅ = 25. If you look at the result in 2), you see that x₅ = 25 there!

So the sequence in this case is the same as before {3, 4, 8, 15, 25, 38}
