Answer:
Correct option is:
C. 2
Step-by-step explanation:
We have to find the exponent in the term -3x²
An exponent refers to the number of times a number is multiplied by itself.
Here, x is multiplied to itself 2 times
i.e.
Hence, exponent in the term -3x² is:
2
So, the correct option is:
C. 2
Answer:
Hector's kite is 61.84 feet from the ground.
Step-by-step explanation:
The angle of elevation of the kite is 42°15’30” when converted to decimals, it is ≅
Let the height of the kite to the horizontal of angle of elevation be represented as x. Applying the trigonometric function to the sketch of Hector's kite,
Sin θ =
Sin =
⇒ x = 86 x Sin
= 86 x 0.6725
= 57.835
x ≅ 57.84 feet
The height of Hector's kite from the ground = x + 4
= 57.84 + 4
= 61.84 feet
