8^_/8^-4=8^9 I hate school btw

Mathematics
1 answer:
Monica [59]2 years ago
6 0
So 8 to the blank power divided by 8 to the negative 4 power=8 to the 9th power so

simplify
8^-4 means a reciprocal so 8^-4 means 1/(8^4) or 1/4096

8^9 is 134217728

so (8^x)/(1/4096)=134217728
multiply both sides by 1/4096
8^x=134217728/4096=32768
32768= 2^15 or 2*2*2*2*2*2*2*2*2*2*2*2*2*2*2 or since we know that 8=2*2*2 we can group the 2's this way  (2*2*2)(2*2*2)(2*2*2)(2*2*2)(2*2*2) we notice that there are 5 groups so 8^5 is the answer so x=5

Determine which set of side measurements could be used to form a right triangle.
musickatia [10]

The set of side measurements that could be used to form a right triangle is 3, 4 and 5 option (D) is correct.

What is a right-angle triangle?

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

It is given that:

The side length of the triangle is shown in the option:

As we know,

Pythagoras' theorem is the square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.

Using Pythagoras' theorem:

From option(D):

3, 4 and 5

(3)² + (4)² = 5²

9 + 16 = 25 (True)

Thus, the set of side measurements that could be used to form a right triangle is 3, 4 and 5 option (D) is correct.

How do you work this out?
Ira Lisetskai [31]
I'm guessing you find the length of the hypotenuse using the pythagorean theorem. 

a² + b² = c²     a and b are the legs and c is the hypotenuse

15² + 8² = c²

225 + 64 = c²

289 = c²

√289 = √c²

17 = c

hope that helps, God bless!
