Answer:

\frac{\sqrt{3} }{2}, because the angles are complementary

Step-by-step explanation:

The sine and the cosine functions are complementary functions.

This means that;

\cos(\theta)=\sin(90-\theta)

Or

\sin(\theta)=\cos(90-\theta)

If \cos(30\degree)=\frac{\sqrt{3}}{2}, then

\sin(60\degree)=\frac{\sqrt{3}}{2}

The correct answer is

\frac{\sqrt{3} }{2}, because the angles are complementary

Well, the answer would be square root of 3 over 2 because of the unit circle. So, the answer choice should be which ever one involved square root 3 over 2

Hello!

Explanation:

Distributive property: → a(b+c)=ab+ac

First do expand.

4(x+1)=4x+4

Then you subtract by 4 from both sides of an equation.

4x+4-4=2x+4-4

Simplify by equation.

4x=2x

Next, subtract by 2x from both sides of an equation.

4x-2x=2x-2x

Simplify.

2x=0

You can also divide by 2 from both sides of an equation.

\frac{2x}{2}= \frac{0}{2}

Finally, simplify by equation and dividing into the groups.

0/2=0

Answer: → \boxed{x=0}

Hope this helps!

What are the determinants for solving this linear system? 5x + 3y = 17 −8x − 3y = 9 |A| = |Ax| = |Ay| =
valentina_108 [34]

For this case we have the following system of equations:

5x + 3y = 17\\-8x - 3y = 9

We can Rewrite the system of equations of the form:

Ax = b

Where,

A: coefficient matrix

x: incognita vector

b: vector solution

We have then:

A=\left[\begin{array}{ccc}5&3\\-8&-3\end{array}\right]

x=\left[\begin{array}{ccc}x\\y\end{array}\right]

b=\left[\begin{array}{ccc}17\\9\end{array}\right]

Then, the determinant of matrix A is given by:

|A|=(5)(-3)-(3)(-8)\\

|A|=-15+24

|A|=9

Answer:

The determinants for solving this linear system are:

|A|=9

Tems11 [23]
A) 1/5 + 5/9

find common denominator:
9*5 = 45

pillow case: 1/5 = 9/45
table cloth: 5/9 = 25/45

9/45 + 25/45 = 34/45 was used 

B. using 45 as the denominator the full piece of cloth would be 45/45
       fraction left over = 45/45 - 34/45 = 11/45 left

C. from A the pillow case uses 9/45, they have 11/45 left, because 9 is less than 11, they have enough to make a pillow case
