Answer:

z < 0

Step-by-step explanation:

Given:

\frac{29}{289}z

Required:

Solve for z

Follow the following steps:

Step 1: Rewrite expression

\frac{29z}{289}

Step 2: Multiply both sides of the inequality by (289)(161)

(161)(289)\frac{29z}{289}

Step 3: Simplify Expression

161 * 29z< 289 * 16z

Step 4: Multiply

4669 z< 4624 z

Step 5: Collect Like Terms

4669 z - 4624 z< 0

Step 6: Subtract

45z< 0

Step 7: Divide both sides by 45

\frac{45z}{45} < \frac{0}{45}

z < 0

Hence, the resul of \frac{29}{289}z is z < 0

Answer:

  $3600

Step-by-step explanation:

In each case, the repair cost exceeded the deductible, so your out-of-pocket cost for 2 repairs is ...

  2 × $1050 = $2100

In addition, you had to pay the premium of $750 per 6-month period, or $1500 per year, so your total was ...

  $2100 +1500 = $3600 . . . out-of-pocket total

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
