Find two consecutive even integers

Fantom [35]

You can set up a system of equations with x being the smaller number and y being the larger number. So the first equation would be 2y=5x-14 and the second equation would be x=y-2. You can solve by substitution and substitute y-2 into the x in the first equation to get 2y=5(y-2)-14. You can solve this out and it ends up simplifying to y=8. So you know the larger number is 8. So since the larger number is 8 and they are consecutive even integers, the smaller number must be 6. So the two numbers would be 6 and 8.

For f(x)=4x+1 and g(x) = x^2 - 5, find (f+g)(x).

Rus_ich [418]

Answer:

(f + g)(x) = x² + 4x - 4

Step-by-step explanation:

The statement (f + g)(x) is the same as f(x) + g(x). In other words, the question simply wants you to add the two functions together.

f(x) = 4x + 1

g(x) = x² - 5

(f + g)(x) <----- Original statement

f(x) + g(x) <----- Rewrite

(4x + 1) + (x² - 5) <----- Substitute the equations in f(x) and g(x)

4x + x² - 4 <----- Add 1 and -5

x² + 4x - 4 <----- Rearrange the terms

If sin(32)=x , then sin(4) cos(4) cos(8) cos(16)=..............

svp [43]

If sin 32 is equal to x, then sin 4 · cos 4 · cos 8 · cos 16 is equal to x/8 by using double angle trigonometric functions.

<h3>How to simplify an expression by trigonometric expressions</h3>

Trigonometric expressions are formulas that utilize trigonometric functions. Trigonometric functions are a kind of trascendental functions, that is, functions that cannot be described in algebraic terms.

In this question we must simplify a given expression by using the following trigonometric formula:

sin 2x = 2 · cos x · cos x (1)

Now we proceed to expand the expression given:

x = sin 32

x = 2 · sin 16 · cos 16

x = 4 · sin 8 · cos 8 · cos 16

x = 8 · sin 4 · cos 4 · cos 8 · cos 16

Thus,

sin 4 · cos 4 · cos 8 · cos 16 = x/8

If sin 32 is equal to x, then sin 4 · cos 4 · cos 8 · cos 16 is equal to x/8 by using double angle trigonometric functions. $\blacksquare$
