State the vertex and axis of symmetry of the graph of y=ax2+c.
Neporo4naja [7]

State the vertex and axis of symmetry of the graph of y=ax^2+c

General form of quadratic equation is y=ax^2 + bx +c

There is no bx in our given equation, so we put 0x

Given equation can be written as y=ax^2 + 0x +c

a=a , b=0

Now we use formula to find vertex

x=\frac{-b}{2a}

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

Now we plug in 0 for 'a' and find out y

y=a(0)^2 + 0x +c= c

So our vertex is (0,c)

The axis of symmetry at x coordinate of vertex

So x=0 is our axis of symmetry

43 centimeters equals blank or blank meters
Montano1993 [528]
1meter=100centimeter
1centimeter=1/100meter

so cm times 1/100=meters
43 times 1/100=43/100meters aka 0.43 meters
43/100 or 0.43 meters

Slope=1/2;(-2,7) <br> Equation:
romanna [79]
Point slope form:
(y-y1) = m (x-x1)

m=slope=1/2
given point (x1,y1) = (-2,7)

(y-7) = 1/2 (x+2)

slope intercept form:

y-7 = 1/2x + 1
y = 1/2x + 8

ANSWER: y=1/2x + 8

GETS BRAINILIST!!!!What number should be placed in the box to help complete the division calculation? long division setup showin
Ilia_Sergeevich [38]

The unknown value is being subtracted from 702 is 650

Step-by-step explanation:

Long division setup showing an incomplete calculation

  • 13 is in the divisor
  • 3302 is in the dividend
  • 2 hundreds and 5 tens is written in the quotient
  • 2600 is subtracted from 3302 to give 702
  • An unknown value represented by a box is being subtracted from 702

We need to find this number

Lets write the steps above

∵ The dividend = 3302

∵ The divisor = 13

- 2 hundreds means 200 and 5 tens means 50

∵ The quotient = 200 + 50 + x

∵ Dividend = divisor × quotient

∴ (13 × 200) + (13 × 50) + (13 × x) = 3302

∵ 13 × 200 = 2600

- Subtract 2600 from the dividend

∴ 3302 - 2600 = 702

∵ 13 × 50 = 650

∴ 702 - 650 = 52 ⇒ 650 is the unknown value

∵ 13 × x = 13x

∵ 52 - 13x = 0

- Add 13 x to both sides

∴ 52 = 13x

- Divide both sides by 13

∴ x = 4

∴ 3302 ÷ 13 = 200 + 50 + 4

∴ 3302 ÷ 13 = 254

∴ From the steps above the missing number subtracted from

   702 is 650

The unknown value is being subtracted from 702 is 650
