Answer:

3*∑ (1/2)^n = 6

Step-by-step explanation:

We have the summation from n = 1 to n = ∞, for:

∑ 3/(2)^(n - 1)

We know that the summation between k = 0, and k = N - 1 for:

∑ r^k = (1 - r^N)/(1 - r)

if we have the summation between k = 0 and k = ∞ - 1 = ∞

(here we used that ∞ is really big, then ∞ - 1 = ∞)

In the numerator we will have the term r^∞, if 0 < r < 1, then r^∞ = 0.

Then if we assume that 0 < r < 1 we can write:

∑ r^k =  1/(1 - r)

In our case, we can rewrite our summation as:

3*∑ (1/2)^n

for n = 0 to  n = ∞

You can see that i changed the limits for n, this does not really matter because we are summing between a number and infinity, the only thing you need to take care is that now the power is n, instead of (n - 1)

Then we have r = (1/2) which is clearly smaller than 1.

then (1/2)

Then this summation is equal to:

3*∑ (1/2)^n = 3*( 1/(1 - 1/2)) = 3*( 1/( 2/2 - 1/2)) = 3*( 1/(1/2)) = 3*2 = 6

3*∑ (1/2)^n = 6

Answer:

y = 4/5x

Step-by-step explanation:

Points on the graph: (5, 4) and (0, 0)

Slope:

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

m=(0-4)/(0-5)

m=(-4)/(-5)

m= 4/5

Slope-intercept:

y - y1 = m(x - x1)

y - 4 = 4/5(x - 5)

y - 4 = 4/5x - 4

y = 4/5x

Answer:

The cost of one gallon of gas in Toronto, Canada is $3.458.

Solution:

Given, One gallon of gasoline in buffalo, New York costs $2.29.  

In Toronto, Canada, one liter of gas costs $0.91.  

There are 3.8 liters in one gallon.  

We have to find how much does one gallon of gas cost in Toronto?

Now, cost of one gallon of gas in Toronto = cost of one litre of gas in Toronto x 3.8 liters for 1 gallon.

Cost of one gallon of gas = 0.91 x 3.8 = 3.458

Hence, the cost of one gallon of gas in Toronto, Canada is $3.458.

Step-by-step explanation:

since area is measured for 2d shapes and surface area is just finding the area of each side separately and adding it together

Using the area formula, the height of the cylinder is found to be approximately 7.87 inches.

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

Use the formula for the volume of a cylinder to relate the radius, height, and volume of the cylinder -

V = πr²h

Where V is the volume, r is the radius, and h is the height of the cylinder.

It is given that the area of the base of the cylinder is 150 square inches.

Since the base of a cylinder is a circle, the area of the base is given by -

A = πr²

Where A is the area of the base and r is the radius.

Solving for r -

r² = A/π = 150/π

Use the given volume and radius to solve for the height -

V = πr²h

1050 = π(150/π)²h

h ≈ 7.87 inches

Therefore, the height is 7.87 inches.
