larisa86 [58]

This is all about operations priority! We have to perform the operations in the right order, remembering that parentheses come first, then powers, then multiplications and then additions:

Start with

$4(10-4)^2+4$

Perform the operations inside parenthesis first:

$4\cdot 6^2+4$

Perform the square:

$4\cdot 36+4$

Perform the product:

$144+4$

Perform the sum:

$148$

Note: you have an extra parenthesis at the end, and none of the options meets the result. I'm afraid that there's a typo in the question, but this should still give you a valid strategy to solve the actual exercise.

Look at the graph.

Rainbow [258]

Answer:

$f(x) =80 \cdot \: {( \frac{1}{4} )}^{x - 1}$

Step-by-step explanation:

Fro the graph, the first three terms of the sequence are 80,20,5,...

This is a geometric sequence with first term

$f(1)= 80$

The common ratio is

$r = \frac{20}{80} = \frac{5}{20} = \frac{1}{4}$

The function is given by

$f(x) = f(1) \cdot \: {r}^{x - 1}$

We substitute the values we got from the graph into this formula to get:

$f(x) =80 \cdot \: {( \frac{1}{4} )}^{x - 1}$

The correct answer is A

A 200-liter tank initially full of water develops a leak at the bottom. Given that 20% of the water leaks out in the first 5 min

Leya [2.2K]

Answer:

127.53 liters left after 10 minutes

Step-by-step explanation:

Let

$A \to Amount$

$t \to time$

Given

$A(0) = 200$ --- initial

$A(5) = 200 * (1 - 20\%) = 160$ --- the amount left, after 5 minutes

Required

$A(10)$ --- amount left after 5 minutes

To do this, we make use of:

$A(t) = A(0) * e^{kt}$

$A(5) = 160$ implies that:

$160 = 200 * e^{k*5}$

Divide both sides by 200

$0.80 = e^{k*5}$

Take natural logarithm of both sides

$\ln(0.80) = \ln(e^{k*5})$

$\ln(0.80) = \ln(e^{5k})$

$\ln(0.80) = 5k\ln(e)$

So, we have:

$-0.223 = 5k$

Divide by 5

$k = -0.045$

So, the function is:

$A(t) = A(0) * e^{kt}$

$A(t) = 200 * e^{-0.045t}$

The amount after 10 minutes is:

$A(10) = 200 * e^{-0.045*10}$

$A(10) = 200 * e^{-0.45}$

$A(10) = 127.53$
