Answer:

d.) 81

Step-by-step explanation:

f(2) would be 27 and 27x3 is 81.

Answer:

Step-by-step explanation:

For the recursive function, f(n+1) = one-half(n)

Thus, when n = 2,

f(3) = 9

If n = 1,

f(2) = 9×3

f(2) = 27

If n = 0,

f(1) = 27 ×3

f(1) = 81

What does 23/2 reduce down to in its simplest form?

Lunna [17]

To simplify this improper fraction we can turn it into a mixed number. The fact that the denominator is 2 and the numerator isn't divisible by 2 shows that it can't simplified any further as a improper fraction.

23/2 = 11 1/2

Best of Luck!

Question 1 Find the missing angle to the nearest degree. 36 14 degrees

Alla [95]

Answer:

23°

Step-by-step explanation:

Let the missing angle be x

Reference angle = missing angle = x

Opposite side to x = 14

Hypotenuse = 36

Applying trigonometric ratio, we have:

$sin(x) = \frac{14}{36}$

$x = sin^{-1}(\frac{14}{36})$

x = 23° (to the nearest degree)

Why does a conjugate pair make a difference of 2 squares?

allsm [11]

Answer:

where one perfect square is subtracted from another, is called a difference of two squares. It arises when (a − b) and (a + b) are multiplied together. This is one example of what is called a special product.

Step-by-step explanation:

Every difference of squares problem can be factored as follows: a2 – b2 = (a + b)(a – b) or (a – b)(a + b). So, all you need to do to factor these types of problems is to determine what numbers squares will produce the desired results. Step 3: Determine if the remaining factors can be factored any further.

Is 4 a solution of 5m + 7 = -3? Justify your . answer.

irina [24]

Answer:

The equality is false because one side is positive and the other side negative.

Step-by-step explanation:

5(4)+7

Multiply the numbers 4 and 5

20+7

add the numbers 20 and 7

27 $\neq$ -3

so the number 4 is not the solution
