How many roots do u thinn

Mathematics
1 answer:
hram777 [196]2 years ago
6 0

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.

A rectangle is twice as long as it is wide. If its area is 50 sq. yd., find the length.
sertanlavr [38]
A = L * W
A = 50
L = 2W

50 = W(2W)
50 = 2W^2
50/2 = W^2
25 = W^2
sqrt 25 = W
5 = W

L = 2W
L = 2(5)
L = 10 <==length is 10 yd

Could you show me the process on how to get the volume. ​
Anettt [7]

Answer:

Volume = length x width x height.

You only need to know one side to figure out the volume of a cube.

The units of measure for volume are cubic units.

Volume is in three-dimensions.

You can multiply the sides in any order.

Which side you call length, width, or height doesn't matter.

Given that f(x) = 2x2 − 96, find x.
NISA [10]
F(x)=2x(2)−96

Step 1: Add -4x to both sides.

xf+ −4x = 4x−96+ −4x

xf −4x= −96

Step 2: Factor out variable x.

x(f−4)= −96

Step 3: Divide both sides by f-4.

x(f−4)/ f−4 = −96/ f−4

x= −96/f−4

Answer:

x= −96/ f−4
