Answer:
C. Point A lies on ray BC
Step-by-step explanation:
Points A and C can be connected by a segment which would be a measure of the distance between the points. Locating point B between AC, makes the three points lying on segment AC.
A ray extends from a point to infinity, a line extend to infinity on both sides, while a segment is known to have two endpoints. Therefore, points AC are the end points of the segment AC, and point B between this segment confirms that point B lies on the segment AC. Therefore, Point A lies on ray BC is not correct.

The graph shows the equation x2 + y2 = 5. Use the slider for a to move the vertical line on the graph. Based on the vertical
line test, is this equation a function? Why or why not?
Answer: This equation is not a function.
Step-by-step explanation:
Ok, a function is something like a "machine".
It takes an input value, x, and transforms it into an output value, y.
Such that for every input x, the function can transform it into only one value of y.
for example, if we have a "function" f(x)
such that f(2) = 3 and f(2) = 4
(for the same input, x = 2, we have two different outputs)
Then this is not a function.
Now, the given equation is:
x^2 + y^2 = 5
This is actually the equation for a circle, centered at the point (0, 0) and with a radius equal to √5.
Then, if we want to transform it into y(x), we can see a problem
If x = 0, we have:
0^2 + y^2 = 5
y^2 = 5
then we have two possible values for y:
y = +√5
y = -√5
Then for one value of x, we have two values of y.
This means that this is not a function.
Answer:
No. The vertical line touches the graph at more than one point at once.
Step-by-step explanation:

The period of y = 2tanx is _____.
Answer:
The period of the function y = 2×tan x is π
Step-by-step explanation:
The tangent function, generally has a period of π radians such that a cycle of the tangent function is completed every π radians
Therefore, where a required number of periods is required to be completed within the π radians range, the number is used to multiply the trigonometric function[ parameter.
From the question, we have;
y = 2×tan x
Which gives the multiplier of the variable x as 1
Therefore, the period of the function y = 2×tan x is π.

Answer:
no feasible solutions
Step-by-step explanation:
There are so many inequalities that determining the area covered by all 5 of them is problematic. Hence, we have reversed all of them in the attached graph, so any feasible solution region would remain white. Alas, there is no such region.
This system of inequalities has no feasible solution.

10) Find the least number that must be subtracted from the following numbers to make them perfect squares. a) 1098 b) 4498
Answer:
a. 9
b. 9.
Step-by-step explanation:
a) √1098 = 33.136
33^3 = 1089
So the answer is 1098 - 1089
= 9.
b) √4498 = 67.067
67^2 = 4489
Answer = 9.
Answer:
a). 9
b). 9
Step-by-step explanation:
a) If you try to subtract 1 to 8 from 1098, it won't make a perfect square. But if you subtract 9 from 1098 (that will make it 1089), it will make a perfect square.
√1089 = 33
33² = 33 × 33 = 1089
So the answer is 9.
b). If you try to subtract 1 to 8 from 4498, it won't make a perfect square. But if you subtract 9 from 4498 (that will make it 4489), it will make a perfect square.
√4489 = 67
67² = 67 × 67 = 4489
So the answer is 9.

Find the values of a and b so that the following
system of linear equations have infinitely solutions:
(1) (2a - 15x + 3y - 5 = 0, 3x + (6 - 1)y - 2 = 0
plz answer step by step
Answer:
a = 15/2, b = 2/5
Step-by-step explanation:
For a system of two linear equations to have infinitely many solutions, the equations must be equivalent to one another.
Assuming a and b to be constants, and since b is absent from equations, there must be a typo where b was mistaken for a 6.
Modified equations:
2a - 15x + 3y - 5 = 0 ...................(1)
3x + (b - 1)y - 2 = 0 .....................(2)
rearrange equations to standard form:
-15x + 3y + 2a-5 = 0 .................(1a)
3x + (b-1)y -2 = 0 ........................(2)
To equalize the coefficient of x, multiply (2) by -5
-15x - 5(b-1) y +10 = 0 ................(2a)
Subtract (2a) from (1a)
3y + 5(b-1)y + 2a-5 -10 = 0 ..............(3)
For the two equations (1a) and (2a) to be identical, coeffients of y and constant term of (3) must equal zero.
3+5(b-1) = 0 .................(4)
3+5b-5 = 0
5b = 2
b = 2/5
2a-5-10 = 0 .....................(5)
a = 15/2

The total number of cupcakes soldduring 5 days was 2087. The number of cupcakes sold by the shop on Thursday was 3 times the cupcakes sold on Monday. How many cupcakes were sold on Thursday?
Answer:
1252
Step-by-step explanation:
We're assuming that the same amount of cupcakes were sold each day.
2087/5 = 417.4
417.4 x 3 = 1252.2
Since we can't sell fractions of a cupcake, 1252 were sold on Thursday.

Earnings per share, EPS is calculated using the formula \large EPS=\frac{NI-PD}{SO}, where NI is net income, PD is preferred dividence, and SO number of outstanding shares.
What is a company's net income if they have $50,000 in preferred dividends and pay out $0.55 per share on 200,000 shares?
Answer: $160,000
Step-by-step explanation:
Given the following :
Earning per share (EPS) = $0.55
Number of outstanding shares = 200,000
Preferred dividend = $50,000
EPS = (NET INCOME - PREFERRED DIVIDEND) / NUMBR OF OUTSTANDING SHARES
0.55 = ( NET INCOME - 50000) / 200000
200000 × 0.55 = NET INCOME - 50000
110,000 = NET INCOME - 50000
NET INCOME = 110,000 + 50,000
NET INCOME = $160,000

Answer:
x=3
Step-by-step explanation:
5/2 ( 3x-1) = 20
Multiply each side by 2/5
2/5 ( 5/2 ( 3x-1) )= 20 *2/5
3x-1 = 8
Add 1 to each side
3x-1+1 = 8+1
3x = 9
Divide each side by 3
3x/3 = 9/3
x =3
Solve the equation 7b-27=8(6+4b)
Answer:
b = -3
Step-by-step explanation:
7b-27=8(6+4b)
Distribute
7b -27 = 48 + 32b
Subtract 7b from each side
7b-7b-27=48+32b-7b
-27 = 48+25b
Subtract 48 from each side
-27-48 = 48+25b -47
-75 = 25b
Divide each side by 25
-75/-25 =25b/25
-3 =b
Answer: b= -3
Step-by-step explanation:
[tex]7b-27=8\left(6+4b\right)[/tex]
distribute
[tex]7b-27=48+32b[/tex]
add 27 to both sides
[tex]7b-27+27=48+32b+27[/tex]
[tex]7b=32b+75[/tex]
subtract 32b on both sides
[tex]7b-32b=32b+75-32b[/tex]
divide -25 on both sides
[tex]-25b=75[/tex]
[tex]b=-3[/tex]

5. Find the product of p(x) and q(x) if p(x) = 2x+7 and q(x) = 4x-9
a. Is p(x) a polynomial? If not, give an explanation.
b. Is q(x) a polynomiala If not, give an explanation.
c. Is the product a polynomials If not, give an explanation,
d. If the product is a polynomial, identify type and degree.
Answer:
p(x), q(x), and their product are all polynomials.
p(x) · q(x) = 6x² + 10x - 63
Step-by-step explanation:
First of all P(x) and q(x) are polynomials because polynomials refer to any sum, difference, or product of a collection of algebraic terms. The word polynomials is general. P(x) and q(x) are polynomials but more specifically they are binomials since they only have two terms. Their product is a polynomial as well, but more specifically its a trinomial because it has three terms.
process of multiplying
Using the distributive property (or foil method) when multiplying p(x) and q(x) you would first get the expression 6x² - 18x + 28x - 63. From here you would combine "like terms". This would give you your final answer of
6x² + 10x - 63. Sorry, I couldn't help you with the D question but I hope this helps ;)

Alice wrote three consecutive even numbers. The sum of these numbers was 252.
Pat wrote three consecutive odd numbers. Pat's numbers were larger than Alice's numbers.
The difference between the largest of Pat's numbers and the largest of Alice's numbers was 25.
What was the sum of Pat's numbers?
Answer:
333
Step-by-step explanation:
Let a represent Alice's numbers and p represent Pat's numbers.
Alice wrote three consecutive even numbers. The sum of the three is 252. This means:
[tex]a+(a+2)+(a+4)=252[/tex]
The first term is even. Each consecutive even term is two more than the previous term. Simplify:
[tex]3a+6=252\\3a=246\\a=84[/tex]
In other words, Alice's first number was 84.
Pat wrote three consecutive odd numbers. His numbers were larger than Alice's numbers. Similar to Alice, we can write:
[tex](p+1)+(p+3)+(p+5)=x[/tex]
The first term is odd. Each consecutive odd term will be 1 more, then 3 more, then 5, etc. We want to find Pat's sum, or x.
We are told that the difference between the largest of Pat's and Alice's numbers is 25. Therefore:
[tex](p+5)-(a+4)=25[/tex]
Simplify. Substitute a. Solve for p:
[tex]p-a+1=25\\p-84=24\\p=108[/tex]
Therefore, Pat's sum is:
[tex](108+1)+(108+3)+(108+5)=333[/tex]

Answer:
x= 0, and x=4
Step-by-step explanation:
x² -x = 3x, we can subtract 3x from both sides
x² -x -3x = 0, combine like terms
x² -4x = 0 , factor x
x *( x-4) = 0, if the product of 2 numbers equals 0 at least one is 0
x=0 and
x-4 = 0, add 4 to both sides
x= 4
Answer:
x=4 simple thing with all problems like this, is if it has a exponent, then half the exponent and add it to the numerical digit on the right of the equals sign, and you have you answer

Answer:
Option (2)
Step-by-step explanation:
In the given circle,
[tex]m(\widehat{CBD})+m(\widehat{CED})[/tex] = 360°
Therefore, 212° + [tex]m(\widehat{CED})[/tex] = 360°
[tex]m(\widehat{CED})=360-212[/tex]
= 148°
Tangent - chord theorem states,
"Angle between a chord and tangent measure the half of the angle measure of the intercepted minor arc."
m∠ACD = [tex]\frac{1}{2}(\widehat{CED})[/tex]
= [tex]\frac{1}{2}(148)[/tex]
= 74°
Therefore, measure of ∠ACD is half the measure of arc CD or 74°.
Option (2) will be the correct option.
Each employee in a company is either right-handed or left-handed.

right-handed
male
left-handed
Total marks: 3
Answer:
32 female - 23 right-handed || 9 left-handed
22 male - 18 right handed || 4 left handed
Step-by-step explanation:
I find it easiest to write all the information out and fill the gaps.
From what we're given, 32 employees are female, that means 22 are male, as 54 - 32 = 22.
We are also given that there are 41 right-handed employees, which means there is 13 left-handed employees by subtraction.
If 18 of the right-handed employees are male, then 23 of them are female, and 4 are left-handed males.
If 23 of the female employees are right-handed, then 9 female employees are left-handed.
It's quite simple if you write everything out :D

Given that T{X: 2<x ≤ 9} where x is an integer. what is n(T)
Answer:
n(T) = 7Step-by-step explanation:
Given the set T{X: 2<x ≤ 9} where x is an integer, the element of the set T will be {3, 4, 5, 6, 7, 8, 9}. note that from the inequality set 2<x ≤ 9, x is not equal to 2 but greater than 2. The inequality can be divided into two as shown;
If 2<x ≤ 9 then 2<x and x≤9
If 2<x, this means x>2 but not equal to 2. This is the reason why 2 is not contained in the set T.
Similarly if x≤9, this shows that x can not be greater than 9 but less than or equal to 9.
Since the set T = {3, 4, 5, 6, 7, 8, 9}, we are to find n(T). n(T) means cardinality of the set T and cardinality of a set is defined as the total number of element in a set.
Hence n()n(T) = 7 (since there are 7 elements in the set T)
