A quadratic function whose vertex is the same as the y-intercept has the equation
y=x^2+k (where k is the y-intercept, with vertex (0,k))

Since the vertex coincides with the y-intercept, the axis of symmetry is x=0.

stiks02 [169]

Answer:

We see that the only complete time-distance pair indicates that she walked 6.4 miles in 2 hours. If she walked at a constant speed, we can conclude that girl walked 3.2 miles in 1 hour. Using this speed, we can find the remaining values in the table. The easier entry to complete is finding out how far she walked in 5 hours: 5 hours⋅3.2 miles/hour=16 miles. To find out how long it took to walk 8 hours we can either notice that 8 is half of 16, so it took half the time to walk half the distance or we can divide 8 miles by 3.2 miles per hour to find that it took 2.5 hours

Solve for x (19x-18) (7x+1) (10x-9)

ExtremeBDS [4]

Answer:

Step-by-step explanation:

Exterior angle property: Exterior angles equals the sum of remote angles

19x - 18 = 7x + 1 + 10x - 9

19x - 18 = 7x + 10x + 1 - 9 {Combine like terms}

19x - 18 = 17x - 8 {Subtract 17x from both sides}

19x - 17x - 18 = -8

2x - 18 = -8 {Add 18 to both sides}

2x = -8 + 18

2x = 10

x = 10/2

x = 5

In the given figure, O is the centre of a circle, TN is a Tangent, AN = 12 cm and OE = 5 cm. Find the length of NE.

sp2606 [1]

Answer:

NE = 8 cm

Step-by-step explanation:

Radius OA = OE = 5 cm

In right triangle OAN, OA² + AN² = ON²

5² + 12² = ON²

ON² = 25 + 144 = 169

so ON = 13 cm

NE = ON - OE = 13 - 5 = 8 cm

Volume = l*b*h

1. Ans 24 unit cubes

Because it had 6 unit cubes as length, 2 unit cunes as breadth and 2 unit cubes as height.

2. Volume = l*b*h
= 30*15*4
=1800 cubic feet
