The graph of an absolute value function has a vertex of (2,3) and crosses the x-axis at (−1,0) and (5,0). What is the equation f
frez [133]

Answer:

Option D.

Step-by-step explanation:

The vertex form of an absolute function is

y=a|x-h|+k

where, a is a constant, (h,k) is vertex.

It is given that, vertex of an absolute function is (2,3). So, h=2 and k=3.

y=a|x-2|+3   ...(1)

It crosses the x-axis at (5,0). So put x=5 and y=0 to find the value of a.

0=a|5-2|+3

-3=3a

-1=a

Put a=-1 in (1).

y=(-1)|x-2|+3

y=-|x-2|+3

Now, put y=0, to find the equation for this absolute value function when y=0.

0=-|x-2|+3

Therefore, the correct option is D.

The difference between the masses is
  4.55·10¹³ kg -1.78·10¹² kg
  = 4.55·10¹³ kg - 0.178·10¹³ kg
  = (4.55 -0.178)·10¹³ kg
  = 4.372·10¹³ kg

Rounded to the appropriate precision, the mass of the Antarctic iceberg exceeds that of the Rock of Gibraltar by ...

Find the volume of a sphere whose surface area is 1256 sq.cm (Take π = 3.14)<br>​
Alekssandra [29.7K]

Curved surface area of a sphere =1256 cm

2

We know that, Curved surface area of a spehre =4πr

2

⟹1256=4×3.14×r

2

⟹r

2

=

4×3.14

1256

⟹r

2

=100

∴r=10 cm

Hence, the answer is 10 cm.

The parabola y=x2y=x^2 y=x 2 y, equals, x, squared is scaled vertically by a factor of 110\dfrac{1}{10} 10 1 ​ start fraction, 1
sweet [91]

Question is not well presented

The parabola y=x² is scaled vertically by a factor of 1/10.

What is the equation of the new parabola?

Answer:

The equation of the new parabola is 0.1x²

Step-by-step explanation:

Given

Parabola: y = x²

Scale = 1/10 = 0.1

The interpretation of this question is that; there's a need to scale the graph in ratio 1:10.

I.e; 1 unit on the parabola is being represented by 10 unit on the scale

So, x (on the new parabola) = 1/10 of old x.

So, the new equation of the parabola = 1/10x²

New equation = 0.1x²

Hence, the equation of the new parabola is calculated as 0.1x²
