For this case we have the following expression:
 \frac{9^2}{(-3)^0} 

 The first thing you should know for this case, is that by power properties we have:
 Every number raised to zero is equal to unity.
 We then have to rewrite the expression:
 \frac{81}{1}
 81
 Answer:
 
The given expression is equal to:

Answer: Since the expression is not clear, the choices might be - 27 or 81 depending on the expression (see below for detailed explanation)


Justification:


1) If expression to evaluate is 9² ÷ (- 3)


2) In that case, the dividend is: 9² = 81

3) So, the division is 81 ÷ (-3) = - 27.

Remember the law of the signs: the division of opposite signs gives a negative result, while the division of equal signs gives a positive result.



4) If the expression to evaluate is 9² ÷ (- 3)⁰


5) 9² = 81, and (-3)⁰ = 1

6) In this case the division becomes 81 ÷ 1 = 81

How do you solve 2sin^2θ = 1 ?
Murrr4er [49]

The value of θ is 45 degrees as sin45° is equal to 1/√2.

<h3>What is trigonometric equation?</h3>

Trigonometric equation refers to an equation consists of a number of trigonometric ratios whose angle is unknown.

<h3>What is the ranges of trigonometric angle?</h3>

Generally trigonometric angles are represented by θ. while solving equations we get the values of θ ranges from 0 degree to 90 degrees.

Given, 2sin²θ = 1

solving the equation

      sin²θ = 1/2

     sinθ = 1/√2

we know sin45° has a specific value 1/√2

   sinθ = sin 45°

now, θ = 45°

hence, the solution is θ = 45 degrees.

Find f(-2) if f(x) = x + x + 7. f(-2) =
Lynna [10]

Answer:

f(-2) = 9

Step-by-step explanation:

Given that,

f(x) = x² + x + 7

We need to find the value of f(-2).

Put x = -2 in the given function.

f(-2) = (-2)² + (-2) + 7

= 4-2+7

= 9

Hence, the value of f(-2) is equal to 9.

The worlds two highest dams are both in Tajikistan. The rogue dam is 35 meters taller than the Nurek dam. together they are 635
galina1969 [7]
This is a sum and difference problem, with the equations
R-N=35
R+N=635
The solution of which is
R=(635+35)/2=335
N=(635-35)/2=300

In general, the sum and difference problem can be solved (most of the time mentally) using
Larger number = (sum + difference)/2
Smaller number = (sum - difference)/2
