Answer:

160

Step-by-step explanation:

NEXT = 2 • NOW

Implies

a(n+1) = 2 × a(n)

a(1) = 10

a(2) = 20

a(3) = 40

a(4) = 80

a(5) = 160

Answer:

160 bacteria

Step-by-step explanation:

We can create an exponential function of the form: y=ab^{x-1}, where a is the initial value, b is the rate, and x is the time.

Here, a = 10 and b = 2, so our equation is:

y=ab^{x-1}

y=10*2^{x-1}

We want the number of bacteria present after the fifth hour, or when x = 5, so we have:

y=10*2^{x-1}

y=10*2^{5-1}=10*2^{4}=10*16=160

There were 160 bacteria.

<h3>What is the distance between two points?</h3>

The distance between two points is defined as the length of the line segment between two places representing their distance.

Given AB with coordinates A(-4,5) and B(12,13).

The formula of the distance between two points is A(x₁, y₁) and B(x₂, y₂) is given by: d (A, B) = √ (x₂ – x₁)² + (y₂ – y₁) ².

x₁ = -4, y₁ = 5

x₂ = 12, y₂ = 13

distance = √ (12 – (-4))² + (13 – 5)²

distance = √ (12 + 4)² + (8)²

distance = √ (16)² + (8)²

distance = √ (256 + 64)

distance = √320

distance = 17.88 units

The horizontal distance is 16 units and the vertical distance is 8 units from A to B which are determined by the graphing method.
