Hi Student!
This question can seem quite complex but it has a simple explanation. Just imagine, what is the purpose of a square root? It shows what can by multiplied against itself and produce the number that is in the square root. That is why when we take the square root of 4 we get 2 and -2 because they both produce the number 4 when we square them. Whenever we square a number, no matter if it's positive or negative, the answer will always be positive. This is because in order to get a negative number only one can be negative to overcome the positive otherwise it's just a double negative.
Therefore, there is a solution to the question of what is the square root of -4. What we do is practically take out the negative because the square root of -1 is equal to i. So we take the following steps
Separate the square root
[tex]\sqrt{-4}[/tex][tex]\sqrt{4}*\sqrt{-1}[/tex]Simplify the expression
[tex]\sqrt{4}*i[/tex][tex]2*i[/tex]Looking at what we have done, we see that although the explanation behind it might seem complex the actual solving portion isn't too hard when explained. Therefore, the solution to the square root of -4 would be 2i.

Which two of the following expressions are equivalent to cos(theta)? answers are cos(2pi+theta), cos(-theta), cos(pi-theta), and cos(pi+theta), also can someone explain this concept to me, i literally dont understand
The expressions which are equivalent to the trigonometric function cos(theta) are cos(2pi+theta) and cos(-theta)
What is the equivalent expression?Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.
The given trigonometric expressions is,
[tex]f(\theta)=\cos\theta[/tex]
The cosine function is the periodic function. The function repeats itself after the 2π. Thus,
[tex]f(\theta)=\cos\theta\\f(\theta)=\cos(2\pi+\theta)[/tex]
The cosine function is an even function. Thus,
[tex]f(\theta)=\cos\theta\\f(\theta)=\cos(-\theta)[/tex]
Thus, the expressions which are equivalent to the trigonometric function cos(theta) are cos(2pi+theta) and cos(-theta)

The odds in favor of winning a prize in the contest of the juice company which gives prizes to anyone finding specially marked caps is 3.2.
What is odds against?In probability, the term odds against is the ratio of probability of non occurring a favorable event to the probability of occurring a favorable event. It can be given as,
[tex]\text{odd against}=\dfrac{P(\overline A)}{P(A)}[/tex]
Here, [tex]P(\overline A)[/tex] is the probability of not occurring a favorable event, and P(A) is the probability of occurring a favorable event.
A juice company gives the prizes to anyone finding specially marked caps on its juice bottles. The 4 bottles have winning cap in 20 bottles. Thus, the probability of winning is,
[tex]P(A)=\dfrac{4}{20}\\P(A)=\dfrac{1}{5}[/tex]
The probability of not winning is,
[tex]P(\overline A)=1-\dfrac{1}{5}\\P=\dfrac{4}{5}[/tex]
Thus, the odd against the winning is,

equation of a circle that has a center of (-4,-1) and passes through (1,-3)
Answer:
[tex](x + 4)^{2} + (y + 1)^{2} = 29[/tex].
Step-by-step explanation:
The equation of a circle of radius [tex]r[/tex] and center [tex](a,\, b)[/tex] is:
[tex](x - a)^{2} + (y - b)^{2} = r^{2}[/tex].
In this question, it is given that the center is [tex](-4,\, -1)[/tex], such that [tex]a = (-4)[/tex] while [tex]b = (-1)[/tex].
The radius of this circle could be found as the distance between the center of this circle, [tex](-4,\, -1)[/tex], and any point on the circle- such as [tex](1,\, -3)[/tex]. Using the distance formula, the radius of this circle would be:
[tex]\begin{aligned}r &= \sqrt{((-4) - 1)^{2} + ((-1) - (-3))^{2}} \\ &= \sqrt{29}\end{aligned}[/tex].
Therefore, the equation of this circle would be:
[tex](x - (-4))^{2} + (y - (-1))^{2} = (\sqrt{29})^{2}[/tex].
Simplify to obtain:
[tex](x + 4)^{2} + (y + 1)^{2} = 29[/tex].

Jordan invests $9,500 into an account that earns 3.25% annual interest. How much will
be in the account after 10 years if the interest rate is compounded daily or continuously?
Which compounded interest rate should Jordan choose?
The amount of money that Jordan will earn at the end of 10 years = $12,587.5
Calculation of compounded interestsThe principal amount invested(P) = $9,500
The annual compounded daily interest rate(R) of the account = 3.25%
The time given (T) = 10 years
Simple interest (SI) = P×T × R/100
SI = 9,500×10×3.25/100
SI= 308750/100
SI= $3087.50
Therefore the total amount that would be in the account after 10 years = $9,500 + $3,087.50
= $12,587.5

Answer:
22
Step-by-step explanation:
the pattern here is to divide the previous number by 3
the first number is 15, divided by 3 to give you the second number:5 ,the second number divided by 3 gives us 5/3
using that principle the first six terms are :
15, 3, 5/3 , 5/9, 5/27, 5/81
(just multiply the denominator by 3)
adding we have
[tex]15 + 5 + \frac{5}{3} + \frac{5}{9} + \frac{5}{27} + \frac{5}{81} = \frac{1820}{81} [/tex]

does the given value make the inequality true x + 9 21 when x = 15
x = 15 is in fact a solution of the given inequality.
Is the inequality true for the given value?
Here we have the inequality:
x + 9 > 21
We want to see if it is true for x = 15, to check it, we need to repace the value:
15 + 9 > 21
24 > 21
This is true, 24 is larger than 21, then we conclude that x = 15 is a solution of the given inequality.

Help me find the figure , area formula and graph the dots and find the area
Answer:
Looking at the given points we know that it is going to be a triangle because it only have 3 points. Therefore the figure is a triangle and the area formula would be [tex]A=\frac{1}{2}*b*h[/tex].
You can look at the attached graph and what we see is that our height of the triangle is from [tex]y=-3[/tex] to [tex]y=4[/tex] which means that our height is 7 units high. We can also see that our base starts at [tex]x=-4[/tex] and ends at [tex]x=4[/tex] making us have a base of 8 units.
We then plug in the values and solve
[tex]A = \frac{1}{2}*7\ units * 8\ units[/tex]
[tex]A = \frac{1}{2}*56\ units^2[/tex]
[tex]A = 28\ units^2[/tex]
Therefore, the area of our triangle is [tex]28\ units^2[/tex]

Step-by-step explanation:
I got you this the answer
The required result of the division can be written as:
1258 ÷ 24 = 52 R 14, where R 14 means "52 with a remainder of 14".
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
For example 4/2 = 2
When you divide 1258 by 24, the result is a whole number with a remainder.
To find the result of this division, you can use a long division.
24 ) 1258 (52

A book store carries 41 Ocean calendars and 48 Space calendars. Every day, the store sells 3 Ocean calendars and 4 Space calendars.
After how many days there are the same number of both calendars left in the store?
Answer:
After 7 days there are the same number of both calendars left in the store
Step-by-step explanation:
Let x be defined by the number of days,
41 total, 3 Ocean calendars sell each day
48 total, 4 Space calendars sell each day
expression: 41 - 3x = 48 - 4x
- we set them equal to find when x amount days are the same for both calendars
- we subtract due to selling each calendars
solving:
41 - 3x = 48 - 4x
add 4x to both sides, trying to get like terms on the same side
41 - 3x + 4x = 48 - 4x + 4x
41 + x = 48
now subtracts 41 from both sides to get x alone
41 - 41 + x = 48 - 41
x = 7
