Answer:
Step-by-step explanation:
I am assuming that i = √(-1)
3i*2i*(m + i)
= 6i^2(m + i)
= -6(m+ i)
= -6m - 6i.
What is the perimeter of a square?
Explanation:
Let the side of a square be represented as "x".
The perimeter of a square is the sum of it's sides. Since the sides are equal, we can add x four times to get the perimeter.
[tex]\rightarrowtail \text{Perimeter of square} = 4 \times x[/tex]
[tex]\rightarrowtail \text{Perimeter of square} = x + x + x + x[/tex]
[tex]\rightarrowtail \boxed{\text{Perimeter of square} = 4x}[/tex]
To find the perimeter of the square, simply substitute the side length of the square into 4(Side length) to find the perimeter.

Answer:
a) [tex]1\frac{1}{4}[/tex]
b) [tex]46.69[/tex]
Step-by-step explanation:
a) To evaluate the value of this long expression, we can split it up into parts that are easy to calculate. [tex]2\frac{1}{3}+\frac{1}{2}-\frac{1}{12}[/tex] is equal to [tex]2+\frac{4}{12}+\frac{6}{12}-\frac{1}{12}[/tex] and since the fractions have the same denominators, you can add the numerators and keep the denominators. This would result in [tex]2\frac{9}{12}[/tex], which is [tex]2\frac{3}{4}[/tex] simplified. So, now we know that the first parentheses are equal to [tex]2\frac{3}{4}[/tex]. Next, we have to calculate [tex]2(\frac{1}{3}+\frac{1}{4})[/tex]. Using the distributive property to expand, we reach [tex]\frac{2}{3}+\frac{2}{4}[/tex] and we bring them both with a denominator of 12 and add to get [tex]\frac{7}{6}[/tex]. Finally, the last square root is equal to [tex]\frac{1}{3}[/tex] because [tex](\frac{1}{3})^2[/tex] is equal to [tex]\frac{1}{9}[/tex]. To find our final answer we put all of our answers together in the expression [tex]2\frac{3}{4}-\frac{7}{6}-\frac{1}{3}[/tex]. Bring all of these fractions to a denominator of 12 to get: [tex]2\frac{9}{12}-\frac{14}{12}-\frac{4}{12}[/tex]. We combine to get [tex]1\frac{1}{4}[/tex].
b) Similar to the previous part, we can split this expression into two parts to make it more manageable; [tex]-4.9(-12+\sqrt{0.81})[/tex] and [tex](2.2)^2*1.59[/tex]. Once we find the value of each, we will get our final answer by subtracting the second from the first (as shown in the expression). [tex]-4.9(-12+\sqrt{0.81})[/tex] is equal to [tex]-4.9(-12+0.9)[/tex] which is [tex]-4.9*-11.1[/tex] which is [tex]54.39[/tex]. [tex](-2.2)^2*1.59[/tex] is equal to [tex]4.84*1.59[/tex] which is [tex]7.6956[/tex]. To get the final answer, we do [tex]54.39-7.6956[/tex] which is [tex]46.6944[/tex]. Rounded to the nearest hundredth, it is [tex]46.69[/tex].

Answer:
x = 15
Step-by-step explanation:
We can see that the angle with a measure of 37° and the angle with (9x + 8)° form a straight line, so they add up to 180°. This means that 37 + 9x + 8 = 180.
Step 1: Combine like terms.
[tex](9x)+(37+8)=180[/tex] [tex]9x+45=180[/tex]Step 2: Subtract 45 from both sides.
[tex]9x+45-45=180-45[/tex] [tex]9x=135[/tex]Step 3: Divide both sides by 9.
[tex]9x/9=135/9[/tex] [tex]x=15[/tex]Therefore, x = 15!

The expression 5⁻¹³× 5⁵ × 2⁵ can be rewritten as 5⁻⁸ × 2⁵.
What is Exponentiation?Exponentiation is the method of writing a number in terms of powers. This method is usually useful for writing larger numbers in an understandable and effective way.
For a number x, suppose x can be written as aᵇ, here 'a' is called the base and 'b' is called the exponent.
We have to write the expression 5⁻¹³× 5⁵ × 2⁵ in a form where each base comes only once.
This can be solved using one of the basic property of exponents as stated below:
xᵃ × xᵇ = xᵃ⁺ᵇ
That is, upon multiplying two exponents with the same base value, we can combine it and add the exponent values.
∴ 5⁻¹³× 5⁵ can be rewritten as 5⁻⁸.
So 5⁻¹³× 5⁵ × 2⁵ = 5⁻⁸ × 2⁵.
Hence the expression 5⁻¹³× 5⁵ × 2⁵ can be rewritten as 5⁻⁸ × 2⁵ where each base comes only once.

Steven’s cat drinks water from a bowl. The following function represents the ounces of water left in the bowl in terms of hours since it was filled. y= -1/2x + 4 Which variable represents the number of hours since the bowl was filled
Considering the given linear function, variable x represents the number of hours since the bowl was filled.
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem, the number of ounces of water left in the bown after x hours is given by:
y = -0.5x + 4.
Variable x is the input, hence, it represents the number of hours since the bowl was filled.
More can be learned about linear functions at https://brainly.com/question/24808124
Answer:
Part A: The number of ounces of water left in the bowl depends on the number of hours since the bowl was filled. So the number of ounces is the dependent quantity. The y-variable represents the dependent quantity. So, the y-variable represents the ounces of water left in the bowl.
Part B: The number of hours since the bowl was filled is the independent quantity. The x-variable represents an independent quantity. So, the x-variable represents the number of hours since the bowl was filled.
Part C: The value 4 is the initial value of the function. It represents the ounces of water in the bowl immediately after the bowl was filled and before the cat drank any water from the bowl.
Part D: The value -1/2 is the function’s rate of change. It represents the change in ounces of water in the bowl with every hour.

Gareth has 15 total quarters and dimes with a total value of $2.10. A photo of a stack of quarters and a stack of dimes is shown. The system of equations can be used to solve for the number of each Gareth has. {Q+D=15 25Q+10D=210 Complete in the table to show the quantities and values of the coins Gareth has.
Answer:
4 Quarters and 11 Dimes
Step-by-step explanation:
In the first equation, we know that [tex]D=15-Q[/tex] If we plug this into the second equation, we get 25q+10(15-Q)=210. If we simplify this equation, we get 25q+150-10q=210, which can be simplified to 15q+150=210. And since 15q=60, q=4. Then, you subtract 4 from 15, to get 11 dimes. So, there are 4 quarters and 11 dimes. Hopefully, this helps!

Find the range of the quadratic function.
y= 3x2 – 18x+ 23
Write your answer as an inequality using x or y as appropriate.
Or, you may instead click on "Empty set" or "All reals" as the answer.
Answer:
-4 ≤ y <∞.
Step-by-step explanation:
y = 3x² - 18x + 23
= 3(x² - 6x) + 23
= 3(x² - 6x + 9) - 27 + 23
= 3(x - 3)² - 4 ≥ -4
So the range is -4 ≤ y <∞.
