Answer:

x^5+5x^4−x^3

Step-by-step explanation:

Expand by distributing terms

x^3x^2+x^3*5x-x^3

Use the product rule x^a+x^b=x^a+b

x^3+2 +x^3*5x-x^3

Simplify 3+2 to 5

x^5+x^3*5x-x^3

Regroup

x^5+5x^33-3^3

Use product rule x^a+x^b=x^a+b

x^5+5x^3+1   -x^3

Simplify 3+1 to 4

Answer: 7.69

Step-by-step explanation:

3.04+w=10.73

W+3.04=10.73

W+3.04-3.04=10.73-3.04

Subtract 3.04 from both sides

W=7.69

Hi!

Given:

[tex]\frac{4}{5} *\frac{1}{4}[/tex]

First, multiply the numerators.

[tex]4*1=4[/tex]

Second, multiply the denominators.

[tex]5*4=20[/tex]

Now we have:

[tex]\frac{4}{20}[/tex]

Last, simplify. 20 and 4 can both be divided by 4.

[tex]\frac{4/4}{20/4} =\frac{1}{5}[/tex]

Your answer is [tex]\frac{1}{5}[/tex]

All are the exponential function.

Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. c is the base and x is the power.

1.  y = f(x) is a exponential function.

Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.

2.  y = h(x) is a exponential function.

Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.

3.  y = g(x) is a exponential function.

Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.

4.  y = k(x) is a exponential function.

Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.

Thus, all are the exponential function.

Answer:

number of sides: 18 sides

Explanation:

                        Total Interior angle = ( n - 2 ) * 180°

Using the formula:

2880° = ( n - 2) * 180°

n - 2 = 16

n = 16 + 2

n = 18 sides

The given coordinates of the vertices of the triangle ΔABC, which are: A(-5, -1), B(-5, -1), and C(-1, -1), gives the side lengths and the angle measures found using Pythagorean theorem, and the law of cosines as follows:

AB = 2, BC = 4, AC ≈ 4.47

m∠B = 90°, m∠A ≈ 63°, m∠C ≈ 27°

Pythagorean theorem states that in a right triangle, the sum of the squares of the legs, is equal to the square of the length of the hypotenuse side.

The vertices of the triangle are; A(-5, 1), B(-5, -1), and C(-1, -1)

The length, l, of a line having points (x₁, y₁) and (x₂, y₂) can be found using Pythagorean theorem as follows;

[tex]l = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}[/tex]

The length of AB = √((-5 - (-5))² + (-1 - 1)²) = 2

Length of BC = √((-1 - (-5))² + (-1 - (-1))²) = 4

Length of AC = √((-1 - (-5))² + (-1 - 1)²) ≈ 4.47

The interior angles can be found using the law of cosines as follows:

a² = b² + c² - 2·b·c·cos(A)

Which gives: 2·b·c·cos(A) = b² + c² - a²

[tex]\angle A = arccos\left(\dfrac{b^2 + c^2 - a^2}{2\cdot b \cdot c} \right)[/tex]

Where:

a, b, and c are the side lengths of the triangle, and ∠A is the angle opposite side a.

Taking AB = c, BC = a, AC = b, gives:

[tex]\angle A = arccos\left(\dfrac{4.47^2 + 2^2 - 4^2}{2\times 4.47 \times 2} \right) \approx 63^{\circ}[/tex]

Similarly, we have:

[tex]\angle B = arccos\left(\dfrac{4^2 + 2^2 - 4.47^2}{2\times 4\times 2} \right) \approx 90^{\circ}[/tex]

Which by the angle sum property of a triangle gives: ∠C = 180° - 90° - 63° = 27°

The option that gives the side lengths and the angle measure is therefore:
