Answer: [tex]10\left(\cos90^{\circ}+i\sin90^{\circ}\right)[/tex]

Step-by-step explanation:

Given

The complex number is [tex]z_1=0+10i[/tex]

Complex number in polar form is given by

[tex]z=r\left(\cos \theta +i\sin \theta\right)[/tex]

Compare it with the given complex number

[tex]r=10[/tex] and [tex]\sin \theta=1[/tex] which implies [tex]\theta[/tex] must be [tex]90^{\circ}[/tex]

So, in the polar form, it is

[tex]z_1=10\left(\cos90^{\circ}+i\sin90^{\circ}\right)\\z_1=10e^{i\frac{\pi}{2}}[/tex]

Answer:

There will be 361 individuals in 4 years.

Step-by-step explanation:

Exponential equation of population decay:

The amount of individuals of a certain population, after t years, with a decay rate of r(as a decimal), is given by:

[tex]A(t) = A(0)(1-r)^t[/tex]

In which A(0) is the initial population and r is the decay rate.

The population of a certain animal species decreases at a rate of 2.5%.

This means that [tex]r = 0.025[/tex]

There are 400 individuals:

This means that [tex]n = 400[/tex]. So

[tex]A(t) = A(0)(1-r)^t[/tex]

[tex]A(t) = 400(1-0.025)^t[/tex]

[tex]A(t) = 400(0.975)^t[/tex]

How many there will be in 4 years?

This is A(4). So

[tex]A(4) = 400(0.975)^4 = 361.4[/tex]

Rounding to the nearest whole number, there will be 361 individuals in 4 years.

Hi there!

[tex]\large\boxed{y = -7}[/tex]

4y - 2(1 - y) = -44

Begin by distributing -2:

4y - 2(1) - 2(-y) = -44

Simplify. A negative times a negative equals positive.

4y - 2 + 2y = -44

Combine like terms:

6y - 2 = -44

Add 2 to both sides:

6y = -42

Divide both sides by 6:

y = -7

The equation in slope intercept form

Solving (3):

[tex]m = -1[/tex]

[tex](x_1,y_1) =(4,-4)[/tex]

The equation in slope intercept form is:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = -1(x - 4) -4[/tex]

Expand

[tex]y = -x + 4 -4[/tex]

[tex]y = -x[/tex]

Solving (5):

[tex]m = -3[/tex]

[tex](x_1,y_1) = (1,-5)[/tex]

The equation in slope intercept form is:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = -3(x - 1) - 5[/tex]

Expand

[tex]y = -3x + 3 - 5[/tex]

[tex]y = -3x -2[/tex]

P.S when it says OVER it me like a fraction

Step-by-step explanation:

Consider a circle of radius  8  centimetres. Recall that the centre angle in a circle is always 360˚ . However, a semi-circle is a circle cut in half. Hence, the centre angle for the semi-circle is cut in half, or has a measure of 180˚

Here's a diagram of what's going on.

Before applying the formula, let's convert 180˚  to radians.

180˚ over 1  times π over 180°

We will now use the formula to determine the area of this semi-circle.

A= 1/2 × π × 8²

A=1/2 × π × 64

A= 32πcm²

We can confirm this using the formula for area of a semi-circle, A= r²π over 2

A= 8²π over 2

A= 32πcm²

Same, so both formulae work.

Step-by-step explanation:

The interquartile range is obtained using the relation :

Third quartile (Q3). - First quartile (Q1)

From. The boxplot :

Q3 = 96

Q1 = 12

Interquartile range (IQR) = Q3 - Q1 = 96 - 12 = 84

Answer:

(-2, 1).

Step-by-step explanation:

When f(x) = 0

4 + 2x = 0

2x = -4

x = -2.

Ehen f(x) = 6

4 + 2x = 6

2x = 6-4 = 2

x = 1.

Step-by-step explanation:

defective rate is 7 out of 100

defective rate of 4, or 3, or 2, or 1 defective is:

7/100 + 6/99 + 5/98 + 4/97 ≈ 22/100

The required probability for fewer than 5 defective rate is 0.10

An industrial machine produces widgets, but it has a 0.07 defective rate.

What is the probability?

Probability, can be define as the ratio of favorable events to the n number of total events.

defective rate fewer than 5

p of 4 defective + p for 3 defective+ p for 2 defective + p for  1 defective.

total p = 4/100 + 3/99 + 2/98 + 1/97 ≈ 0.10

Thus, The required probability for fewer than 5 defective rate is 0.10

Answer:

B.) Graph of a cubic polynomial that falls to the left and rises to the right with x intercepts negative 3, 2, and 3. The graph intersects the y axis at a point between 15 and 20.

Step-by-step explanation:

Cubic graph falls to the left and rises to the right. Option C is the correct answer.

We need to identify the graph graph best represents the function f(x) = (x − 1)(x + 3)(x − 3).

A cubic function is a polynomial function of degree 3 and is of the form f(x) = ax³+ bx² + cx + d, where a, b, c, and d are real numbers and a ≠ 0.

Graph the cubic using its end behaviour and a few selected points. Falls to the left and rises to the right.

Plot these points on graph (-1, 16), (0, 9), (1, 0), (2, -5) and (3, 0).

Therefore, option C is the correct answer.
