Answer:

2 units wide, 8 units long

Step-by-step explanation:

In this situation, width x length = area. Therefore, the two numbers in the correct answer must correctly multiply to 16.

4 x 2 = 8, so 4 units by 2 units is incorrect.

2 x 6 = 12, so 2 units by 6 units is incorrect.

4 x 3 = 12, so 4 units by 3 units is incorrect.

2 x 8 = 16, so 2 units by 8 units is correct.

In a class of 40 students, 5 like neither Nokia nor

Vikki [24]

Answer:

No student liked only Nokia

Step-by-step explanation:

The information can be illustrated as shown on the Venn diagram.

The number of students who liked only Nokia is x.

The sum of all regions in the Venn diagram should be 40.

We add all to get:

$5 + 5 + 30 + x = 40$

$40 + x = 40$

$x = 40 - 40$

$x = 0$

Therefore no one liked only Nokia

Solve the equation. And write all solutions in general form.

Amiraneli [1.4K]

Answer:

x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer

x = 5pi /3 + 2 pi n

Step-by-step explanation:

8 cos^2 x + 4 cos x-4 = 0

Divide by 4

2 cos^2 x + cos x-1 = 0

Let u = cos x

2 u^2 +u -1 =0

Factor

(2u -1) ( u+1) = 0

Using the zero product property

2u-1 =0 u+1 =0

u = 1/2 u = -1

Substitute cosx for u

cos x = 1/2 cos x = -1

Take the inverse cos on each side

cos ^-1(cos x) = cos ^-1(1/2) cos ^-1( cos x) =cos ^-1( -1)

x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer

x = 5pi /3 + 2 pi n

A rhombus, which is a quadrilateral with 44 equal sides, is plotted on the coordinate plane. The coordinates of the vertices are

Arturiano [62]

The rhombus is shown in the diagram below

The length of one side of the rhombus is 5 units, hence all the other sides are also 5 units each.
