Given:
The point is (8,5).
To find:
A point on the y-axis such that its distance from the point (8,5) is 10 units.
Solution:
Let the required point on the y-axis be (0,k).
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The distance between (8,5) and (0,k) is 10 units. Using distance formula, we get
[tex]10=\sqrt{(0-8)^2+(k-5)^2}[/tex]
Taking square on both sides.
[tex]100=64+(k-5)^2[/tex]
[tex]100-64=(k-5)^2[/tex]
[tex]36=(k-5)^2[/tex]
Taking square root on both sides.
[tex]\pm \sqrt{36}=k-5[/tex]
[tex]\pm 6=k-5[/tex]
Now,
[tex]6=k-5[/tex] and [tex]-6=k-5[/tex]
[tex]6+5=k[/tex] and [tex]-6+5=k[/tex]
[tex]11=k[/tex] and [tex]-1=k[/tex]
Therefore, the required point is either (0,11) or (0,-1).

Given that log, xy = 2 + 3 log, x - log, y, express y in terms of x.
Answer:
the answer could be y=10+×
Step-by-step explanation:
its a long calculation.First,separate log xy into log x +log y and do it like usual way of doing algebra.then,cancel log(change 2 to log 10^2 bfr that) and u must get y^2=10^2+x^2.then square root the whole equation.

Abdul buys dress pants from a clothing Company for P dollars he sells each pair of pants in his men's clothing shop at 40% markup select all the expressions below represent the new retail price of a pair of dress pants
Answer:
$P + 0.4P or 1.4P
Step-by-step explanation:
Given that:
Cost of dress pants = $P
Markup on cost price = 40%
The new retail price of a pair of dress pant :
(Cost price of the dress pant + markup on cost price)
$P + 40% of P
$P + 0.4P
New retail price = $P + 0.4P = 1.4P

One ninth of the students in Mr. Beck’s class list red as their favorite color. Twice as many students call blue their favorite, and three times as many students prefer pink. The rest name green as their favorite color. If 6 students call blue their favorite color, how many students are in Mr. Beck’s class?
Answer:
27
Step-by-step explanation:
this is because 6 students is 2/9th of the class and if we divide that by two we get 3. 3 is 1/9th od the class so we multiply it by 9 to get 27 which is how many students should be in his class if i am right
A recent survey suggests that 47% of all televisions are connected to the internet, 32% are voice controlled, and 22% are both connected to the internet and voice controlled. Suppose a television is selected at random and it is voice controlled. What is the probability that a randomly selected voice-controlled television is also connected to the internet?
A. 0.15
B. 0.47
C. 0.69
D. 0.79
Answer:
0.69
Step-by-step explanation:
Here, we want to find the probability that a randomly selected television is connected to the internet given that it is voice-controlled
let P(V) is the probability of selecting a voice controlled television
P(I) is the probability that a selected television is connected to the internet
So the probability we want to calculate according to Baye’s theorem will be;
P(I|V) = P(I n V)/P(V)
P( I n V) = 22%
P(V) = 32%
So the probability is;
22%/32% = 0.6875 which is approximately 0.69
Answer: 0.69

I need to now the measurements on of A and B
Answer:
A = 90° and B = 145°
Step-by-step explanation:
We already know that A is a right angle because it looks just like one. A trapezoid has a total of 360 degrees. We can create an equation to solve for the 4th angle.
90 + 90 + 145 + x = 360
325 + x = 360
x = 35
Now, we can find B. Angle B and 35 make a supplementary angle. This means that both angles when added will equal 180 degrees. We can create an equation and solve.
35 + B = 180
B = 145

what is the mean of 2 4 5 6 8
Answer:
The mean of 2 4 6 8 is 6
bc Means is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
Step-by-step explanation:
Hope this helps :)
A mean is an arithmetic average of a set of observations. The mean of 2, 4, 5, 6, and 8 is 5.
What is Mean?A mean is an arithmetic average of a set of observations. it is given by the formula,
Mean = (Sum of observations)/Number of observations
The mean of 2, 4, 5, 6, and 8 can be written as,
Mean = (2+4+5+6+8)/5 = 25/5 = 5
Hence, the mean of 2, 4, 5, 6, and 8 is 5.

Twice the square of a number is less than another number. Negating the square of that number and adding 5 causes
it to be larger than the other number. Which represents the solution set?
Answer:
d
Step-by-step explanation:
took it on edg
The graph d represents the solution set of the inequalities 2x^2 < y and -x^2 + 5 > y
How to represent the solution set?First, we represent the mathematical statements as an equation or inequalities
Mathematically, the statements in the questions are:
2x^2 < y-x^2 + 5 > yWhere x and y represents the two numbers
So, we plot the graphs of 2x^2 < y and -x^2 + 5 > y
The graph d represents the solution set of the inequalities 2x^2 < y and -x^2 + 5 > y

At a college bookstore, Tanisha bought a Math Textbook and a Novel for $54. If the price of the Math Textbook is $8 more than 3 times the price of the Novel, then how much is the price of each book?
Answer: Price of Math Textbook= $42.5, Price of the Novel= $11.5
Step-by-step explanation:
Let x = price of the Novel.
Price of Math Textbook = 8+3x
As per given , we have
Price of Math Textbook + Price of the Novel = $54
⇒ 8+3x+x = 54
⇒ 8+4x=54
⇒ 4x = 46 [subtract 8 from both sides]
⇒ x = 11.5
Price of Math Textbook = 8+3(11.5) = 8+34.5= $42.5
Hence, Price of Math Textbook= $42.5, Price of the Novel= $11.5
