Answer:

a = -2.872 and 3.272

Step-by-step explanation:

Given the equation 5a^2-2a-47=0

Using the general formula;

a = 2±√2²-4(5)(-47)/2(5)

a = 2±√4+940/10

a = 2±√944/10

a = 2±30.72/10

a = 2-30.72/10 and 2+30.72/10

a = -28.72/10 and 32.72/10

a = -2.872 and 3.272

A forest cover 43,000 acres. A survey finds that 0.2% of the forest is old growth tress. How many acres of old growth trees are

Sveta_85 [38]

Given:

Total forest area = 43,000

Old growth trees forest = 0.2%

To find:

The area of the old growth trees.

Solution:

We have,

Total forest area = 43,000

Old growth trees forest = 0.2%

Area of the old growth trees = 0.2% of 43,000

= $\dfrac{0.2}{100}\times 43000$

= $86$

Therefore, the area of the old growth trees is 86 acres.

Please solve the question below 88

RideAnS [48]

Answer:

7361.56 yards

Step-by-step explanation:

Height of the tower = 906 yards

Mauricio's height = 2 yards

Angle of elevation = $7^{o}$

Let the distance between Mauricio and the base of the tower be represented by x.

The difference between the height of tower and Mauricio's height = 906 - 2

= 904 yards

So that applying the appropriate trigonometric function, we have;

Tan θ = $\frac{opposite}{adjacent}$

Tan $7^{o}$ = $\frac{904}{x}$

0.1228 = $\frac{904}{x}$

x = $\frac{904}{0.1228}$

= 7361.5635

x = 7361.56 yards

The distance between Mauricio and the base of the tower is 7361.56 yards.
