Aleks [24]

Answer:

10 years ago

Step-by-step explanation:

Let x be the number of years ago

x years ago,

Sonu's grandmother was 80 - x

Sonu was 20 - x

x years ago,

the grandmother was 7 times as old as Sonu

80 - x = 7(20 - x)

80 - x = 140 - 7x

6x = 60

x = 10

12 cm<br> 8 cm<br> Find the volume of the cylinder
ki77a [65]

Answer:

ubstitute the value of the radius r = 8.0 cm height h = 12.0 cm into the formula to find the volume. Pi (π) is approximately equal to 3.14 .

π x 82 cm2 x 12 cm

Raise 8 cm power of 2

π x 64.0 cm2 x 12 cm

Multiply 64.0 cm2 and 12 cm

π x 768.0 cm3

Combine π and 768.0 cm3

The result can be shown in multiple forms.

Exact Form

Volume = 768.0π cm3

∴ Volume of Cylinder radius 8 cm and height 12 cm is 768.0π cm3

Decimal Form

Volume = 2411.52 cm3

How many roots do u thinn
hram777 [196]

Answer:

  • 2 roots
  • 1 root

Step-by-step explanation:

Each equation is in vertex form, so you can easily determine the number of real roots. The leading coefficient tells you whether the parabola opens upward (positive) or downward (negative).

  y = a(x -h)^2 +k

has leading coefficient "a" and vertex (h, k).

__

<u>f(x) = 1/3(x +5)^2 +7</u>

  vertex: (-5, 7), opens downward

The vertex is above the x-axis, so there are two real roots.

__

<u>f(x) = -5(x -3)^2</u>

  vertex: (3, 0), opens downward

The vertex is on the x-axis, so there is one real root.
