cosxcos(x+pi divided by 4)=0
0

Answers

Answer 1

Answer:

Step-by-step explanation:

hello : solutions in R

cosxcos((x+π)/4) =0

means :   cosx = 0   or   cos((x+π)/4) =0

1)   cosx = 0    means : x = π/2+kπ    k in Z

2)  cos((x+π)/4) =0  means :  (x+π)/4 =  π/2+kπ .......continu calculate : x

What is a function?

A function can be defined as a law, rule or expression that shows the relationship between two variables in an equation.

These variables are called;

The independent variableThe dependent variable

From the information given, we have the function;

f(x) = (x + 1)² g(x) = 2x³

To determine the composite function, we have to substitute the value of g(x) as x in the function f(x), we have;

(f º g)(x) = (2x³ + 1)²

expand the bracket

(f º g)(x) = 4x⁶ + 1

Hence, the function is (f º g)(x) = 4x⁶ + 1

Answers

Answer: One solution

Step-by-step explanation:

y = 3x + 3

y = -2x + 3

-----------------------------------------------------------------------------------------------------------

To solve this, you need to understand a few things:

a) If two lines have the same slope but different y-intercepts, they are parallel when graphed and thus do not have any solutions

b) If two lines have the same slope and same y-intercepts, they are the same line when graphed and thus do not have infinitely many solutions

c) If two lines have different slopes (and/or y-intercepts), they have one solution

-----------------------------------------------------------------------------------------------------------

These two lines have different slopes but the same y-intercept (condition c)

So they have one solution

Find the measure of the given angles

Answers

Hey there!

The answer is 58 degrees

Since ΔABC ~ ΔDEF, then m∠A ~ m∠D, and m∠B ~ m∠E, and m∠C ~ m∠F. This means we can set m∠A equal to m∠D:

x + 29 = 2x

Subtract x from both sides:

29 = x

Now, we plug into the angle expressions to find their measurement:

m∠A = 29 + 29

m∠A = 58

Since they are equal, m∠A and m∠D are both 58 degrees.

Have a terrificly amazing day! :)
