The kinetic energy of an object is given by the formula E = mv2. If m is in kg and v is in m/s,
then E is in joules. What is the kinetic energy of an electron (mass = 9.1 x 10-31kg) travelling at a
fifth of the speed of light (speed of light, c = 3 x 108m/s)?

Answers

Answer 1

Answer:

9.553×10^-26

Step-by-step explanation:

m= 9.1 ×10 ^-31

v = 3 × 108

= ( 9 .1 × 10 ^- 31) × ( 3 × 108 ) ^2

= 9 .552816 × 10 ^ -26

approximately

9.553×10 ^26

At practice, Carlos eats half as many apples as Alex, and also eats 2 tangerines. He eats 4 pieces of fruit in total. The equation 0.5x + 2 = 4 describes this situation. What does the variable represent?

Answers

Answer:

Step-by-step explanation:

In this scenario, the variable x represents the total number of apples that Alex has eaten. Since Carlos has eaten half as many apples as Alex this would be represented as 0.5 and is why it is being multiplied by the variable x. The 2 in this scenario represents the tangerines that Carlos has also eaten, while the 4 represents the total number of fruits that Carlos has eaten.

Answer:

Step-by-step explanation:

[tex]AV=PV(1+i)^n\\AV=24750(1+.0125)^3\\25689.77[/tex]

Answer:

$25,689.775

Step-by-step explanation:

The interest has to be in decimal form. So 1.25/100=0.0125

Plug everything into the equation for compound equation [tex]A=P(1+\frac{r}{t})^{n}^{t}[/tex]

Which is A = 24750 [(1 + 0.0125/1)^(1)(3)]

Type them in a calculator and get A ≈ $25,689.775

***the question says "compounded annually" so the equation for compound interest [tex]A=P(1+\frac{r}{t})^{n}^{t}[/tex] should be used. Your provided formula of A = P(1 + R times T) shouldn't be used here, it is for simple interest but not compound.*** (^_^)

What is the minimum value for the function shown in the graph?

Answers

Answer:

2.5

The lowest point on the graph, or the minimum is at f(x)= 2.5

The minimum value of the given periodic function is, 2.5

What are functions?

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

A periodic function,

Period  = 3π

The value of the function is in the range of (2.5, 4.5)

So,

Maximum value = 4.5

Minimum value  = 2.5

Thus, the minimum value is 2.5

The Height of triangular face is 692.820 feet,

The height of Pyramid is 800 feet.

What is pyramid?

A pyramid is a three-dimensional polyhedron with three or more faces that are triangle-shaped and meet above the base. Faces are the triangular sides, and the apex is the point above the base. A pyramid is made by interfacing the base to the peak. To differentiate them from the base, the triangular sides are sometimes referred to as lateral faces. Each edge of the base of a pyramid connects to the apex that makes up the triangular face.

Given to Draw a Pyramid, with square base

and triangular faces are Equilateral,

length of Square base = 800 feet

The Drawing  of pyramid is attached,

which shows h = height of pyramid

S = height of Triangular face

And base = 800 feet

2: To find height of Triangular face

since triangular face are Equilateral

side of triangle = base of pyramid = 800 feet

and height of Equilateral triangle  = √3/2 × a

where a is side of triangle

S =  √3/2 × a = √3/2 × 800

S = 692.820 feet

3: As we have height of triangle so we can calculate the height of pyramid by relation between height of triangle and height of pyramid

h² = S² + (x/2)²

where x is the length of side of base,

x/2 = 800/2 = 400

substitute values of S and x/2

h² = (400√3)² + (400)²

h² = 480000 + 160000

h² = 640000

h = 800 feet

Hence, the height of triangular face is 692.820 feet,

and the height of Pyramid is 800 feet.
