Help me please number 3

Mathematics
1 answer:
asambeis [7]2 years ago
3 0

Answer:

c = 26

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem.

a^2 + b^2 = c^2

where a and b are the legs and c is the hypotenuse

10^2 + 24^2 = c^2

100 + 576 = c^2

676 = c^2

Take the square root of each side

sqrt(676) = sqrt(c^2)

26 = c

gayaneshka [121]

Answer:

<h3>Part A</h3>
  • d(n) = n(n + 1)/2
  • n = 1 ⇒ d(1) = 1(1 + 1)/2 = 2/2 = 1, proved
<h3>Part B</h3>
  • d(k) + (k + 1) =
  • k(k + 1)/2 + (k + 1) =
  • [k(k + 1) + 2(k + 1)]/2 =
  • [(k + 1)(k + 1 + 1)]/2 =
  • d(k + 1)
  • Proved

Please help me with this&gt;If you help me i will give you brainliest
Komok [63]

Answer:

Step-by-step explanation:

So its difficult to show

Y= X-6 so what ever x is, y is six less than that so

X= -4 Y= -10

X= 0 Y=-4

X=4 Y=0

X=8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= 4/3x -2 so whatever x is y is 4/3 and 2 less then that

X=-4 Y= -5

X=0 Y= -2

X=4 Y=1

X= 8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= -2

Find minus 2 on the y axis and draw a horizontal line through it all the way across the grid.

Y= 2+ 1/4x  so whatever x is y is 1/4 of x add 2

X=-8 Y= 0

X= -4  Y = 1

X=0 Y=2

X=4 Y=3

X=8 Y=4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Do this method for 9

y = 2x -3 so whatever x is, y is  2 times that -3

y=2x +1 so whatever x is y is 2 times that +1

y= 2x so whatever x is y is 2 times that

Then plot the answers on a graph like co-ordinates (x,y) and draw a straight line through them

Make sure to label each line

Hope this helps
