5 0

Answer:

R30 : R60

Step-by-step explanation:

sum the parts of the ratio, 1 + 2 = 3 parts

Divide the amount by 3 to find the value of 1 part of the ratio

R90 ÷ 3 = R30 , then

2 parts = R30 × 2 = R60

R90 in ratio 1 : 2 = R30 : R60

The graph shown represents the number of bacteria in a dish after a certain number of minutes. It is a function in the form f(x)
SSSSS [86.1K]

Answer:

The number of bacteria in the dish after 9.9 minutes is 478

Step-by-step explanation:

The form of the function is f(x)=a.b^{x} , where a is the initial amount (value f(x) at x = 0)

To find a and b let us use two points from the graph and substitute their coordinates in the equation

∵ The graph passes through point (1 , 1)

∴ x = 1 and y = 1

- Substitute them in the equation

∵ 1=a.b^{1}

∴ a.b = 1 ⇒ (1)

∵ The graph passes through point (1 , 1)

∴ x = 3 and y = 4

- Substitute them in the equation

∵ 4=a.b^{3}

∴ a.b³ = 4 ⇒ (2)

Use equation (1) to find a in terms of b

∵ a.b = 1

- Divide both sides by b

∴ a=\frac{1}{b} ⇒ (3)

- Substitute a in equation (2) by equation (3)

∴ \frac{1}{b} . b³ = 4

- Remember the rule \frac{a^{m}}{a^{n}}=a^{m-n}

∵ \frac{1}{b} . b³ = b^{3-1} = b²

∴ b² = 4

- Take √  for both sides

∴ b = 2

Substitute the value of b in equation (3) to find a

∵ a = \frac{1}{2}

∴ a = 0.5

∴ f(x)=0.5(2)^{x}

∵ f(x) represents the number of bacteria after x minutes

∵ x = 9.9 minutes

- Substitute x by 9.9 to find the number of bacteria

∵ f(9.9)=0.5(2)^{9.9}

∴ f(9.9) = 477.7128917

- Round it to the nearest whole number

∴ f(9.9) = 478

∴ The number of bacteria in the dish after 9.9 minutes is 478
