Please someone should help me solve it 2x ÷ x^ - 4

Mathematics
1 answer:
Vaselesa [24]3 years ago
3 0

Answer:

The answer is

<h2>{2x}^{5}</h2>

Step-by-step explanation:

<h3>\frac{2x}{ {x}^{ - 4} }</h3>

First of all separate the two from the x

That's

<h3>\frac{2(x)}{ {x}^{ - 4} }</h3>

Next we use the rules of indices

Since they have the same base and are dividing we subtract the exponents

That's

<h3>\frac{ {a}^{x} }{ {a}^{y} }  =  {a}^{x - y}</h3>

So we have

<h3>\frac{2(x)}{ {x}^{ - 4} }  = 2( {x}^{1 -  - 4)}  = 2( {x}^{1 + 4} )</h3>

We have the final answer as

<h3>{2x}^{5}</h3>

Hope this helps you

Given :

Martin drinks 1/4 of a litre of juice each day.

Juice costs £3.60 for a 2 litre carton and £2.00 for a 1 litre carton.

To Find :

Martin buys enough juice to last for 2 weeks (14 days).

What is the lowest price Martin can pay for this juice.

Solution :

Amount of litre used in 14 days is :

V = 14× ( 1/4 )

V = 3.5 liter

Lowest price to pay is :

P = 2 × Cost of one 2 L carton

P = £(2 × 3.60)

P = £7.2

The lowest price Martin can pay for this juice is £7.2 .

Hence, this is the required solution.

What is the volume of this sphere? use 3.14 for pi and round to the nearest hundredth when necessary.
Harrizon [31]

The volume of the sphere is 900 cm³

Step-by-step explanation:

  • Step 1: Given the diameter of the ball = 12 cm. Find radius.

Radius = diameter/2 = 12/2 = 6cm

  • Use the formula for volume of a sphere to find the volume.

Volume of the ball = 4/3 πr³

                              = 4/3 × 3.14 × (6)³

                              = 904.32 cm³ ≈ 900 cm³ (nearest hundredth)

Use the information in the diagram to determine the height of the tree to the nearest foot.
algol13

Answer:

The correct option is A. The height of tree is 60 ft.

Step-by-step explanation:

From the given figure it is noticed that the building is creating a right angle triangle from a point and the tree divides the hypotenuse and base in two equal part.

According to midpoint theorem of triangle: In a triangle, if a line segment connecting the midpoints of two sides, then the line is parallel to third side. The length of line segment is half of the length of third side.

Using midpoint theorem of triangle, we can say that the length of tree is half of the building.

Tree=\frac{1}{2}\times Building

Tree=\frac{1}{2}\times 120

Tree=60

Therefore correct option is A. The height of tree is 60 ft.
