The answer is 0. after you do everything in the parenthesis it would be 4-2•2 use pemdas and because multiplication comes before subtraction, you would get 4-4 which is 2.

JulijaS [17]

Answer:

40 is the missing angle

Step-by-step explanation:

all straight angles must add up to 180

so if we add 80+60=140 then do 180-140=40

that should be the answer

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:

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

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

$A(10) = 127.53$

The weights and heights of six mathematics students are given in the following table:

Verizon [17]

Answer:

c. Weight is input, height is output

Step-by-step explanation:

It is given here that "Height is a function of Weight".

which means

$Height = f(Weight)$

Thus, value of Height is depend on the value of Weight.

Thus, Weight is input variable and Height is output variable.

Hence option (c) is correct.

Further,

The variable that we can change is called the Input variable.

The Output variable depends upon the input variable, as we change the value of the input variable the value of the output variable is also get changed.
