Answer:

50 degrees.

Step-by-step explanation:

The three angles make up a straight line angle which = 180 degrees, so:

C = 180 - 65 - 65

= 50 degrees.

Answer:

50

Step-by-step explanation:

So in forth-fifth grade you had to learn that a straight line is 180 degrees right? So the first thing that you do is you add 65+65 and then you get 130 degrees. But we're not done yet. Now we have to subtract 180 - 130 and you get 50 degrees. So the answer is 50 degrees.

Hope this helps! Please give Brainlist! Please!!

What is the mode of these numbers: 10, 13, 800, 24 and 13
OverLord2011 [107]
A mode is the number that appears the most in a set of numbers. (I'm going to put the numbers in order before I solve this) 

10, 13, 13, 24, 800

The answer is 13, because it appears more than any of the other numbers. :)

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

A. Rewrite the function y = x2 – 14x + 58 in vertex form by completing the square. Show your work. B. Rewrite the function y = –
marysya [2.9K]

Answer:

A. y = (x -7)² +9

B. y = -(x +3)² -11

C. minimum, (7, 9)

D. maximum, (-3, -11)

Step-by-step explanation:

The general steps to rewriting the function in vertex form are ...

1. factor out the leading coefficient (if not 1) from the first two terms

2. add inside parentheses the square of half the x coefficient; subtract the same amount outside parentheses. The factor in front of the parentheses must be taken into account when adding the same amount outside.

3. rewrite the content of parentheses as a square, collect terms outside parentheses.

___

A. y = x² -14x +58

y = (x² -14x) +58 . . . . . . . . . . step 1

y = (x² -14x +49) +58 -49 . . . step 2

y = (x -7)² +9 . . . . . . . . . . . . . step 3

__

B. y = -x² -6x -20

y = -(x² +6x) -20

y = -(x² +6x +9) -20 -(-9)

y = -(x +3)² -11

__

C. In vertex form, the function for vertical scale factor "a" and vertex (h, k) looks like ...

y = a(x -h)² +k

When a < 0, the vertex is a maximum (the graph opens downward); when a > 0, the vertex is a minimum (the graph opens upward).

The function of part A has a minimum at the vertex (7, 9). 9 is the minimum value.

___

D. The function of part B has a maximum at the vertex (-3, -11). -11 is the maximum value.

Max measures and records his height every year. This year, as a fifth grader, his height is 5 1/6 feet. He has grown 1 1/4 feet
gtnhenbr [62]

Answer:

  3 11/12 feet

Step-by-step explanation:

(5 1/6 ft) - (1 1/4 ft) = (5 2/12 ft) - (1 3/12 ft) = (5 -1) ft +(2/12 -3/12) ft

  = 4 ft - 1/12 ft

  = 3 11/12 ft . . . . Max's height in second grade
