If the last three digits of a number are divisible by 8, then the number is completely divisible by 8. So we can check the last three digits of a number to know whether they are a multiple of 8.
A multiple of 8 is a number that can be evenly divided by 8 without a remainder. To determine if a number is a multiple of 8, you can divide it by 8 and check if the quotient is an integer (a whole number with no remainder).
For example, to check if the number 96 is a multiple of 8, you can divide 96 by 8 and the quotient is 12, which is an integer, so 96 is a multiple of 8.
Another way to check if a number is a multiple of 8 is to check if the last three digits of the number are 000 or divisible by 8. This is because 8 is a power of 2 (2^3=8), and any number that is a multiple of 8 will be divisible by 2^3, which means it must have 3 trailing zeroes.
A more general method to check if a number is a multiple of any number is by using the modulo operator, which returns the remainder of a division. If x is a multiple of y, then x mod y = 0. Therefore, you can use x % 8 == 0 to check if x is a multiple of 8.

Write your answer as a decimal.
Answer:
j = 1.5
Step-by-step explanation:
You want to solve the equation 0.3j-(0.1j-3) + 0.1 = 2 (j+0.1) + 0.2 for the value of j.
SimplifyIt usually works well to simplify such an equation as the first step. That means eliminating parentheses and combining like terms.

Additional comment
You are often taught to solve this kind of 3-step equation by subtracting the unwanted variable term and the unwanted constant term in two steps. (The third step is dividing by the coefficient of the variable.) Here, we show those subtractions being done both at once.
The variable term we choose to subtract is the one with the smallest coefficient. That way, the result of the subtraction (1.8j) leaves the coefficient of the variable as a positive number.
Sometimes the variable term on the right is subtracted, so you end up with a "j = " equation. In that case, the equation you would be solving as the last step is ...
-1.8j = -2.7
which requires arithmetic with negative numbers. Negative numbers tend to be associated with more mistakes, so we choose not to go there.

Find the volume of a pyramid with a square base, where the area of the base is 4. 6\text{ cm}^24. 6 cm 2 and the height of the pyramid is 2. 3\text{ cm}2. 3 cm. Round your answer to the nearest tenth of a cubic centimeter.
The volume of the pyramid is 3.5 cubic centimeters.
The volume of a pyramid can be calculated using the formula:
V = (1/3) * Base area * Height
Where Base area is the area of the base of the pyramid, and Height is the distance from the base to the apex of the pyramid.
Given that the area of the base of the pyramid is 4.6 cm^2 and the height of the pyramid is 2.3 cm, we can substitute these values into the formula and solve for the volume:
V = (1/3) * 4.6 cm^2 * 2.3 cm = 3.53 cm^3
So the volume of the pyramid is 3.53 cubic centimeters. Rounded to the nearest tenth of a cubic centimeter, the volume is 3.5 cm^3.

Answer:
First question(unnumbered):
[tex]\mathrm{Choice \; (B) : \;\;\dfrac{1}{2}}[/tex]

[tex]\mathrm{Choice \;(C)\;\; (x, y) = \left(-1, \dfrac{3}{2}\right)}[/tex]
Question 49
[tex]\mathrm{Choice \; (D)\;\;-1}[/tex]
Step-by-step explanation:
The imaginary variable i is [tex]\sqrt{-1}[/tex] and [tex]i^2 = -1[/tex]
For the unnumbered first question we have
the equation
[tex]\dfrac{1}{1-i}[/tex]
Multiply numerator and denominator by [tex]i + 1[/tex]
[tex]\rightarrow \dfrac{1\cdot \left(1+i\right)}{\left(1-i\right)\left(1+i\right)}\\\\\\= \dfrac{1 + i}{1 - i^2} \;\;\;\;\;\;\;since \;(a +b)(a-b) = a^2 - b^2\\\\\textrm{Since $i^2 = -1$, the denominator becomes:}\\\\1-i^2 = 1 -(-1) = 2\\\\\\[/tex]
Therefore ,
[tex]\dfrac{1}{1-i} = \dfrac{1 + i}{2}\\\\= \dfrac{1}{2} + \dfrac{i}{2}\\\\[/tex]
The real part is [tex]\dfrac{1}{2}[/tex] and the imaginary part is [tex]\dfrac{i}{2}[/tex]

Solve [tex](x, y)[/tex] for [tex]2y\:+\:xi\:=\:4+x-i[/tex] for [tex]$x,y\in\mathbb{R}$[/tex]
For the equation
[tex]2y\:+\:xi\:=\:4+x-i[/tex]
Move the the x and i terms from the right to left side:
[tex]2y + xi - x + i = 4\\\\2y - x +xi + i =4\\\\[/tex]
Since this works out to a real number, the imaginary part is 0
So
[tex]xi + i = 0\\\\xi = -i\\\\x = \dfrac{-i}{i}\\\\x = -1[/tex]
and the real part
[tex]2y - x = 4[/tex]
Substitute for x = -1 in the above to get
[tex]2y -(-1) = 4\\\\2y + 1 = 4\\\\2y = 4-1\\\\2y = 3\\\\y = \dfrac{3}{2}\\\\[/tex]
[tex](x, y) = \left(-1, \dfrac{3}{2}\right)[/tex]

Since i² = -1 this works out to:

Find Dy/Dx By Implicit Differentiation. 5x^2-xy-4y^2=0
The Implicit Differentiation of 5x^2-xy-4y^2=0 is Dy/Dx= (5x-y)/(-4y)
Using implicit differentiation, Dy/Dx can be found by taking the derivative of both sides with respect to x.
On the left side, the derivative with respect to x of 5x2 is 10x and the derivative with respect to x of -xy is -y.
On the right side, the derivative of 4y2 with respect to x is 0.
Therefore, the equation becomes 10x - y = 0.
Solving for y gives y = 10x.
Substituting this into the original equation, we get 5x2 - 10x2 - 4(10x)2 = 0, which simplifies to -5x2 - 40x2 = 0.
Finally, we can solve for Dy/Dx:
Dy/Dx= (5x-10x)/(-4(10x))
Dy/Dx= (5x-y)/(-4y)

Answer:
y = 13
Step-by-step explanation:
given (7, 33 ) is a solution of the top equation, then
x = 7, y = 33 satisfies the equation , that is
33 = 7a + 5 ( subtract 5 from both sides )
28 = 7a ( divide both sides by 4 )
4 = a
then
y = 4x + 5 ← top equation
substitute y = 4x + 5 into the other equation
9x + 2(4x + 5) = 44
9x + 8x + 10 = 44
17x + 10 = 44 ( subtract 10 from both sides )
17x = 34 ( divide both sides by 17 )
x = 2
substitute x = 2 into the top equation for value of y
y = 4x + 5 = 4(2) + 5 = 8 + 5 = 13

How to obtain the length of the race track?The length of the race track is obtained applying the proportions in the context of this problem.
His car stops 10m past the starting line. After he fixes a wheel, the car goes 2/5 the racetrack’s total distance and then stops for good. It is 38m from the starting line, hence the distance driven during this entire period is of:
38 - 10 - 28 m.
28 m is 2/5 of the track length, which is going to be called x, hence the equation is given as follows:
2x/5 = 28.
The track length is then obtained as follows:
2x = 5 x 28
x = 5 x 14
x = 70 meters.

1) Ed invests $1,000 into a money market account that earns 8% annual interest compounded quarterly. How much money will
he have earned after 8 years?
The money market account earns 8/4 = 2% interest per quarter.
In one year, there are 4 quarters.
so, the formula to calculate the balance after 8 years is:
A = P (1 + r/n)^(nt)
where A is the final balance, P is the principal (initial investment), r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years the money is invested for.
Substituting in the given values,
A = 1000 (1 + .02)^(4*8)
A = 1000 (1.02)^32
A = 1000 (1.8587)
A = 1858.7
So after 8 years, Ed will have earned $1858.7.
