Please help me I really need it!!!! Find the midpoint of BD.
Answer:
The midpoint of [tex]\overline{BD}[/tex] is [tex](\frac{a}{2},\frac{a}{2})[/tex].
Step-by-step explanation:
Consider the provided information.
We need to find the midpoint of [tex]\overline{BD}[/tex].
For this, we will use the midpoint formula: [tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Now put [tex](x_1,y_1)=(0,a)[/tex] and [tex](x_2,y_2)=(a,0)[/tex] in the above formula and solve for M.
[tex]M=(\frac{0+a}{2},\frac{a+0}{2})[/tex]
[tex]M=(\frac{a}{2},\frac{a}{2})[/tex]
Hence, the midpoint of [tex]\overline{BD}[/tex] is [tex](\frac{a}{2},\frac{a}{2})[/tex].

What is the value of (4-2)3-3x4
Answer:
The answer is -4.
Step-by-step explanation:
It is -4 using the method of PEMDAS. Subtract 4 and 2 together in the parentheses to get 2. Multiply to the third root power to get 8. Then, multiply -3 by 4 together to get -12. Finally, subtract 12 from 8 to get -4 as your final answer.

A line passes through point A(12,18). A second point on the line has an x-value that is 125% of the x-value of point A and a y-value that is 75% of the y-value of point A. Use point A to write an equation of the line in point-slope form.
PLEASE! PUT THIS IN POINT SLOPE FORM!
Answer:
y - 18 = -1.5(x - 12)
Step-by-step explanation:
A = (12, 18)
B=(1.25(12), 0.75(18)) = (15, 13.5)
Find slope: m = (13.5-18)/(15-12) = (-4.5)/3 = -1.5
Point slope form: y - y1 = m(x - x1)
Using point A as (x1, y1)
y - 18 = -1.5(x - 12)

Write the ratio 3/5 to 6 as a fraction in simplest form
Answer:
1/10
Step-by-step explanation:
To convert a ratio to a fraction, you divide the number on the left by the number on the right. This gets you (3/5)/6. When dividing fractions by whole numbers, you need to convert the whole number to a fraction. I converted 6 to 6/1, so that gave me (3/5)/(6/1). You then multiply the top number by the bottom number to get the numerator of the answer, and the middle 2 numbers multiplied is the denominator. The answer is (3x1)/(5x6), or 3/30, which can be simplified to 1/10.

Q#1: Suppose that you have two different algorithms for solving a problem. To solve a problem of size n, the first algorithm uses exactly n*exp1-[n+2n+3n+4n]/nlne(10) operations and the second algorithm uses exactly n! operations. As n grows, which algorithm uses fewer operations?
Answer:
The one of -[n+2n+3n+4n]/nlne(10) has fewer operations because the value of n is static.
The one of n! ( factorial ) is factorised up to n∞ hence has infinity operations.

Your student email account requires you to choose a password of 4 letters followed by one of the digits 0-9. The password can consist of upper case letters (26) or lower case letters (26).
How many different five-character passwords can be created?
Answer: 520
Step-by-step explanation:
Total choices for letters = upper case letters (26) + lower case letters (26).
= 26+26 = 52
Choices for digits = 10
By Fundamental counting principle,
The different five character passwords can be created = (Choices for letters) x (Choices for digits)
= 52 x 10
= 520
Hence, the number of different five character passwords can be created = 520

Nori had 2 1/12 bags of apples. He used 1 5/12 bags of apples to make pies How many bags of apples does Nori has left
Answer:
3 1/2
Step-by-step explanation:
Answer is 8/12.
Mixed number Fraction:
A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
(Here),
Nori had [tex]2\frac{1}{12}[/tex] bags of apples.
Given, he used [tex]1\frac{5}{12}[/tex] bags of apples.
Nori left = [tex]2\frac{1}{12}[/tex] - [tex]1\frac{5}{12}[/tex]
=> (25 / 12) - (17 / 12)

complete the statement to describe the expression (a+b+c)(d+e+f).
the expression consists of ? factors, and each factor contains ? terms.
Answers:
the expression consists of 2 factorseach factor has 3 terms==============================================
Explanation:
The two factors are (a+b+c) and (d+e+f). A factor is a part of multiplication. So in general if we multiply x and y, then x and y are factors to lead to the product x*y.
The expression a+b+c has three terms. Each term is separated by a plus sign.
The expression d+e+f also has three terms.

Answer:
1) 135°
2) 0.77 units
3) 0.92 units
4) 6.12 units
5) 2.83 square units
Step-by-step explanation:
1) The exterior angle at any vertex is 360°/n, where n is the number of sides. For the octagon, the exterior angle is 360°/8 = 45°. The interior angle will be the supplement of this: 180° -45° = 135°.
The measure of each interior angle is 135°.
__
2) Each sector of the octagon is an isosceles triangle with a central angle of 45° (also 360°/8). Since the radius is 1 unit, the length of one side is twice the sine of half the central angle.
s = 2·sin(45°/2) ≈ 0.765367
The length of one side is about 0.77 units.
__
3) Similarly, the apothem is the cosine of half the central angle:
a = cos(45°/2) ≈ 0.923880
The apothem is about 0.92 units.
__
4) For an octagon, the perimeter is 8 times the length of one side.
P = 8s = 8(0.765367) ≈ 6.12293
The perimeter is about 6.12 units.
__
5) The area of one sector (isosceles triangle) is given by the formula ...
A = (1/2)bh
A = 1/2sa ≈ 1/2(0.765367)(0.923880) ≈ 0.353553
Then the area of the octagon is 8 times this:
A = 8(sector area) = 8(0.353553) ≈ 2.82843
The octagon area is about 2.83 square units.

The local fitness center is running two different monthly payment options to attract new customers. The options are shown below.
What is the rate of change for the plans and at what number of visits would the plans cost the same amount?
Answer: The rate is increasing upwards, if that is what you were asking?
Step-by-step explanation: Let me know if you need anything else, please :)
The rate of change for payment option 1 is 1 and for payment option 2 is 0.25.
At 4th visit the cost of both the plans will be same.
What is the slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is its graph or the rate of change is large.
We know the slope m = (y₂ - y₁)/(x₂ - x₁).
Payment option 1 has two points (0, 2) and (2, 4).
Slope(m₁) = (4 - 2)/(2 - 0).
Slope(m₁) = 2/2
Slope(m₁) = 1.
4 = 2(1) + b.
b = 2.
y = x + 2.
Payment option 2 has,
$0.25 every visit is $(1/4) and it is the rate of change or the slope.
y = 0.25x + 5.
The number of visits when the cost will be equal is when we'll equate these two equations,
x + 2 = 0.25x + 5.
x - 0.25x = 5 - 2.
0.75x = 3.
x = 3/0.75.
x = 4.
At 4 visits the cost of each plan will be the same.
