THE NUBER OF PEOPLE CONTACTED
Elis [28]

Answer:

option c, x = 3

Step-by-step explanation:

Given:

  • f(x) = 27
  • f(x) = 3^{x}

Since both equal f(x) they must be equivalent as well,

3^{x} = 27\\

Apply exponent rule, 3 x 3 x 3 = 27

hence x = 3

Allushta [10]

Answer:

Step-by-step explanation:

We can use Hypotenuse Theorem for this:

For triangle ABC,

AC²=CB²+BA²

9²=CB²+3²

Switch the sides

-CB²=3² -9²

-CB²= 9-81

-CB²= -72

the signs cut each other

CB²=72

the square changes sides

CB=√72

CB= 8.49 cm

Now triangle CBD

We have the length of CB but not the other two whereas we have the angle

It will be sin

As we know sin= O/H

Here O is CB whereas H is CD

Put the values

sin 50= 8.49/H

H= 8.49 ÷sin 50

Calculate

H=11.1 cm

As we know H is CD so CD is 11.1 cm

Hope it helps
