Answer:

12

Step-by-step explanation:

Average age of 5 boys = 11 year

Sum of age of 5 boys = 11*5 = 55

Age of sixth boy = 17 years

Sum of age of 6 boys = 55 + 17 = 72

Average age of 6 boys= 72/6 = 12

The hypotenuse of a triangle measures 12 inches, and the measure of one of the acute angles is two less than three times the mea
olga_2 [115]

Answer:

26 sq in.

Step-by-step explanation:

Let x = measure of one acute angle

3x - 2 = measure of other acute angle

Since the triangle is a right triangle, the sum of the measures of the acute angles is 90

x + 3x - 2 = 90

4x - 2 = 90

4x = 92

x = 23

90 - 23 = 67

The acute angles are 23° and 67°

Now, let a = length of side opposite the 23° angle

sin 23 = a/12

a = 12 sin 23

Let b = length of the side opposite the 67° angle

sin 67 = b/12

b = 12 sin 67

Area = 1/2ab = 1/2(12 sin 23°)(12 sin 67°)

                     = 25.90

26 sq in to the nearest inch

Wow!  That is quite the problem.

Decide whether the function is an exponential growth or exponential decay function, and find the constant percentage rate of gro
Rasek [7]

Answer:

Exponential decay function; -0.94%

Step-by-step explanation:

We are given an exponential function and we are supposed to find whether the given function increases or decreases and also the percentage of increase or decrease.

Th given function is f(x) = 2060\times (0.9906)^{x}

Here x denotes the number of years.

At the start the value was 2060. In the next year it was multiplied by 0.9906.

This means that the value becomes 0.9906 times after each year.

Hence the value decreases by 0.0094 times its original value.

Converting to percentage it becomes 0.94% decrease after each year.
