Answer:
Step-by-step explanation:
Given:
Required
Equivalent expression without fraction
To do this, we simply multiply through by a common multiple of the denominators in the expression.
The denominators are 2 and 3
So, 6 is the least common multiple.
Multiply both sides by 6
<em>Hence, an equivalent expression.</em>
Answer:
x tan q
Step-by-step explanation:
Refer the attached figure
An observer on the ground is x meters from the base of the launch pad of a rocket i.e. BC = x
The height of the rocket is AB
The observer sees its tip at an angle of q° from the horizontal.i.e.∠ACB = q°
In ΔABC
We will use trigonometric ratio
So, the height of the rocket is x tan q.
So, Option C is correct.
Hence the tip of the rocket is x tan q far above the ground
Answer:
4:9
Step-by-step explanation:
Not travelling: travelling
12 : 27
4 : 9
12 and 27 have 3 as a common factor
Therefore the ratio can be simplified to:
12/3 : 27/3
4 : 9
Answer:
Step-by-step explanation:
3^4 · 3^-9 = 3^4 · 1/3^9
