Answer:

C )For n = 3 the expression 4n+ 3 is composite number.

Step-by-step explanation:

Given : 4n + 3.

To find: Which value of n makes the value of the expression 4n+3 a composite number is it.

Solution : We have given 4n + 3.

Composite number : A composite number is a positive integer which is not prime (i.e., which has factors other than 1 and itself).

For, n = 3

4 (3) + 3

12 + 3

15 .

We can see 15 is not a prime number . it has factor 3 , 5, 15 .

So, For n = 3 the expression 4n+ 3 is composite number.

Therefore, C )For n = 3 the expression 4n+ 3 is composite number.

Answer:

1974.6 feets

Step-by-step explanation:

The plane's altitude is : h + 100 feets

To obtain h, according to the attached picture ;

We can use trigonometry :

Tan θ = opposite / Adjacent

Opposite = h ; adjacent = 3000 feets

Tan 32° = h / 3000

h = 3000 * 0.6248693

h = 1874.6080

Plane's altitude :

h + 100 feets

(1874.6080 + 100) feets

= 1974.6 feets

Solve for k. k/4 + 3 = 14 k =

Leto [7]

Answer:

The answer is k = 44.

Step-by-step explanation:

1) Subtract 3 from both sides.

$\frac{k}{4} = 14 - 3$

2) Simplify 14 - 3 to 11.

$\frac{k}{4} = 11$

3) Multiply both sides by 4.

$k = 11 \times 4$

4) Simplify 11 × 4 to 44.

$k = 44$

Therefor, the answer is k = 44.
