Answer:
-64
Step-by-step explanation:
The question is asking to solve 
Notice how the -4 is in parenthesis. This means that along with the 4 being multiplied, the negative is too.
is the same as -4 · -4 · -4
First let's figure out if this will be negative or positive
Whenever the exponent is odd and there is a negative in the parenthesis the answer will be negative and if its even it will be positive
Now find out what 4 x 4 x 4 equals (64)
In conclusion the answer is -64

Step-by-step explanation:
1 11/20 = 31/20 = 1.55 and 1.55 =1.55
Answer:
-9
Step-by-step explanation:
First, we pay attention to the numerical coefficients of the terms in the series: 10, 21, 32, 43, 54, 65. Conclusively they form an arithmetic sequence with a common difference of 11. Thus, the next numerical coefficient is 76. Then, we pay attention to the letters which are just arrange alphabetically. The next letter ought to be G which needs to be capitalized. Thus, the answer is letter C. 76G.

Answer:
80.5°
Step-by-step explanation:
The applicable trig function is the tangent.
Tan = Opposite/Adjacent
In this scenario, the side opposite the angle is the tower height, 324 m. The side adjacent is the distance to the tower, 54 m. Then the angle α is related by ...
tan(α) = 324/54
The value of the angle with this tangent is found using the arctangent function:
α = arctan(324/54) ≈ 80.5°
She should set her binoculars to 80.5°.
