I need the answer for the parentheses

Mathematics
1 answer:
jolli1 [7]3 years ago
7 0

Answer:

Step-by-step explanation:

To find the vertex, we need to put this into vertex form, which is done by completing the square on the quadratic. Begin by moving the 8 over to he other side of the equals sign:

3x^2-6x=-8

Now factor out the 3:

3(x^2-2x)=-8

Now take half the linear term, square it, and add it to both sides. Our linear term is 2. Half of 2 is 1, and 1 squared is 1:

3(x^2-2x+1)=-8+3

We added a 3 on the right because 3 times the 1 we added in is 3. Cleaning that up a bit gives us the perfect square binomial on the left and -5 on the right:

3(x-1)^2=-5

and when we move the -5 back over by adding we have

3(x-1)^2+5=y and our vertex is seen to be (1, 5)

Joey and his band have just recorded 14 new songs. The band decides that they want the new songs to form an album. How many ways
Natali [406]

Answer:

87,178,291,200 ways

Step-by-step explanation:

Number of songs = 14

To Form an album with the 14 songs, the number of ways at which the 14 songs can be arranged is obtained by calculating the factorial of the number of songs ;

Number of ways in which the 14 songs can be arranged :

14! = (14 * 13 * 12 * 11* 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) = 87178291200 ways

The figure shows a map of five streets that meet at Concord Circle. The measure of the angle formed by Melville Road and Emerson
Dovator [93]

Alright, lets get started.

Please refer the diagram I have attached.

The angle between Melville Road and Emerson Avenue is 119°.

Hawthorne Lane bisects the angle formed by Melville Road and Emerson Avenue.

So, angle between Hawthorne Lane and Emerson Avenue will be = \frac{1}{2} * 119 = 59.5°

Now, angle between Emerson Avenue and Thoreau Street is 135°.

Dickinson Drive bisects the angle formed by Emerson Avenue and Thoreau Street.

So, angle between Dickinson Drive and Emerson Avenue will be = \frac{1}{2} * 135 = 67.5°

So, the complete angle between Hawthorne Lane and Dickinson Drive will be = 59.5 + 67.5 = 127°

So, the answer is 127 °.   :    Answer

Hope it will help :)

The solutions to the inequality y < to -x+1 sre shaded on the graph. Which point is a solution
Citrus2011 [14]
<h3>Answer:  B.  (3,-2)</h3>

There are two ways to confirm this is the answer. The first is to note that (3,-2) is on the boundary, so it is part of the solution set. This only works if the boundary line is a solid line (as opposed to a dashed or dotted line).

The second way is to plug (x,y) = (3,-2) into the given inequality to find that

y \le -x+1\\\\-2 \le -3+1\\\\-2 \le -2

which is a true statement. So this confirms that (3,-2) is in the solution set of the inequality.
