During a rainfall, the depth of water in a rain gauge increases at a rate modeled by r(t)=0.5+tcos(πt380) r ( t ) = 0.5 + t cos

Tresset [83]

The function r(t)= 0.5 + t cos(πt³/80) is an illustration of a cosine function

The depth of water in the rain gauge increases by 1.466cm from t = 0 to t = 3

<h3>How to determine the increase in water depth?</h3>

The function is given as:

r(t)= 0.5 + t cos(πt³/80)

When t = 0, the depth of water is:

r(0)= 0.5 + 0 * cos(π *0³/80)

Evaluate

r(0) = 0.5

When t = 3, the depth of water is:

r(3)= 0.5 + 3 * cos(π *3³/80)

Evaluate

r(3)= 1.966

Calculate the difference (d) in the depths

d = r(3) - r(0)

So, we have:

d = 1.966 - 0.5

Evaluate

d = 1.466

Hence, the depth of water in the rain gauge increases by 1.466cm from t = 0 to t = 3

Two friends are planning for a gathering. the food budget is modeled by one half times the absolute value of the quantity x minu

Georgia [21]

The least and greatest amounts that the two friends could spend on food would be 114 and 146.

We have,

The food budget is modeled by an equation,

i.e.

$\frac{1}{2}$ |x - 130| = 8

Here,

x = the amount spent on food

So,

Now,

According to the question,

To find the least and greatest amounts that the two friends could spend on food,

We have to,

Find absolute value of the quantity x,

i.e.

$\frac{1}{2}$ |x - 130| = 8

We get,

|x - 130| = 16

i.e.

x - 130 = ± 16

So,

The least amount will be, when we take negative value,

i.e.

x - 130 = - 16

On solving we get,

x = 114,

NOw,

The greatest amount will be, when we take positive value,

i.e.

x - 130 = 16

On solving we get,

x = 146,

So,

The least amount is 114 and greatest amount is 146.

Hence we can say that the least and greatest amounts that the two friends could spend on food would be 114 and 146.
