The number of cases of flu on day 15 will be 1001 flus

<h3>
Exponential functions</h3>

Exponential functions are expressed as y = ab^x

Given the expression below

f(x)=10001+999e^{-0.6030x}

In order to determine the number of cases of flu on day 15, we will substitute x = 15 into the expression to have:

f(x)=10001+999e^{-0.6030(15)}\\f(x)=10001+999e^{-9.045}\\f(15) = 10001+0.11786\\f(15) \approx 10001

Hence the number of cases of flu on day 15 will be 1001 flus

33 is 55% of what number
9966 [12]
Because percentage is the numerator divided by the denominator of a fraction times one-hundred, we can set up this equation:

\frac{33}{x} =0.55

Now, we cross multiply.

33= 0.55x

Next, we divide both sides by 0.55 to get x by itself.

x = 60

So, 33 is 55% of 60.

ANTONII [103]

The surface area of the triangular prism is 828 in².

Solution:

Let the missing length of the triangle be x.

Using Pythagoras theorem,

In right triangle, square of the hypotenuse is equal to the sum of the squares of other two sides.

12^2+x^2=15^2

144+x^2=225

Subtract 144 on both sides of the equation.

x^2=225-144

x^2=81

Taking square root on both sides, we get

x = 9

The missing length of the triangle is 9 in.

Area of the front triangle = \frac{1}{2}\times 12\times 9

                                         = 54 in²

Area of the back triangle = \frac{1}{2}\times 12\times 9

                                         = 54 in²

Area of the sloping rectangle = 20 × 9

                                                 = 180 in²

Area of the back rectangle = 20 × 12

                                             = 240 in²

Area of the base rectangle = 20 × 15

                                             = 300 in²

Total area = 54 in² + 54 in² + 180 in² + 240 in² + 300 in²

                 = 828 in²

The surface area of the triangular prism is 828 in².
