Find the equation of the line that contains the point (1,-5) and has a slope that is undefined. Express the equation using either the general form or the slope-intercept form of the equation of a line.
The equation of the line is
Answers
Answer:
x=1
Step-by-step explanation:
Since the slope is undefined, it's of the form x=a and since it passes through (1,-5) the equation is x=1
The equation of the vertical line in slope-intercept form is: x = 1.
What is the Equation of a Vertical Line?A vertical line has an undefined slope and therefore has no y-intercept. the equation of a vertical line is therefore expressed as, x = a, where a is the x-intercept, which is the value of x of the point where the vertical line intersects the x-axis..
Given the point (1, -5), since the line has an undefined slope, the equation in slope-intercept form would be: x = 1.

Find the center of a circle with the equation: x2+y2−4x+2y−11=0 x 2 + y 2 − 4 x + 2 y − 11 = 0
Answers
Answer:
( 2, - 1 )
Step-by-step explanation:
( x - h )² + ( y - k )² = r²
( h, k ) are coordinates of the center of a circle with radius r
~~~~~~~~~
x² + y² - 4x + 2y - 11 = 0
( x² - 4x + 4 ) - 4 + ( y² + 2y + 1 ) - 1 - 11 = 0
( x - 2 )² + ( y + 1 )² = 4²
Coordinates of the center of a circle are ( 2, - 1 )

Question 10: If the product of all the numbers from 1 to 100 is divisible by 2^n, then what is the maximum possible value for n: A. 128; B. 87; C. 64; D. 97; E. 70.
Answers
Answer: D
Step-by-step explanation:
100!=2*3*4*...*100
Counting which numbers are divisible by 2:
2,4,6,8,10,12,14,...,96,98,100 : 50 numbers (100/2=50)
Counting which numbers are divisible by 4=2²:
4,8,12,16,20,...96,100: 25 numbers (100/4=25)
Counting which numbers are divisible by 8=2³:
8,16,24,32,40,...,96: 12 numbers (100/8=12.5 ==> 12)
Counting which numbers are divisible by 16=2⁴:
16,32,48,...,96: 6 numbers (100/16=6.25 ==> 6)
Counting which numbers are divisible by 32=2⁵:
32,64,96 : 3 numbers(100/32=3.125 ==>3)
Counting which numbers are divisible by 64=2⁶:
64 : 1 number (100/64=1.5625 ==>1)
Sum of those numbers= 50+25+12+6+3+1=97
100! is divisible by 2⁹⁷.
Answer D
There are 25 multiples of 4
There are 12 multiples of 8
There are 6 multiples of 16
There are 3 multiples of 32
There is one multiple of 64
Each of these is also counted in the line above
So the unique multiples are (1 x 64) x (2 x 32) x (3 x 16) x (6 x 8) x (13 x 4) x (25 x 2)
= (1 x 2^6) x (2 x 2^5) x (3 x 2^4) x (6 x 2^3) x (13 x 2^2) x (25 x 2^1)
So n = 6 + 10 + 12 + 18 + 26 + 25 = 97
The slow (but easier way) to see this is to write down all the even numbers in factors of 2 and count the number of 2S
Eg 2, 2x2, 2x3, 2x2x2, 2x5, 2x2x3, 2x7, 2x2x2x2, 2x9, 2x2x5, 2x11, 2x2x2x3, 2x13, 2x2x7, 2x15 etc
(This only got to 30 but you should get the idea - there are 26 twos up to there)

Find the x-intercept and y-intercept of the line.
4x+5y= -20
Answers
Answer:y-intercept = -20/5 = -4 x-intercept = -20/4 = -5
Step-by-step explanation:
Answer:
x- intercept = - 5, y- intercept = - 4
Step-by-step explanation:
The x- intercept is where the line crosses the x- axis.
The y- coordinate of any point on the x- axis is zero
Substitute y = 0 into the equation and solve for x
4x + 5(0) = - 20
4x = - 20 ( divide both sides by 4 )
x = - 5 ← x- intercept or (- 5, 0 ) in coordinate form
The y- intercept is where the line crosses the y- axis
The x- coordinate of any point on the y- axis is zero
Substitute x = 0 into the equation and solve for y
4(0) + 5y = - 20
5y = - 20 ( divide both sides by 5 )
y = - 4 ← y- intercept or (0, - 4 ) in coordinate form

Step-by-step explanation:
you heard of the Pythagoras formula for rectangular triangles ?
c² = a² + b²
c is the Hypotenuse (the side opposite of the 90 degree angle), a and b are the other 2 sides touching the 90 degree angle.
so, in your case here we have therefore
x² = 8² + 6² = 64 + 36 = 100
x = sqrt(100) = 10
you know "sqrt" is an international abbreviation for square root : the opposite of squaring a number.

Answers
Total number of houses use hotspot is 18 houses
Step-by-step explanation:
Given that;
Number of total houses = 35
AT&T providers Internet service = [tex]\frac{1}{5}[/tex] of total house
Spectrum providers Internet service = [tex]\frac{2}{7}[/tex] of total house
Find:
Total number of houses use hotspot
Computation:
Number of houses AT&T providers Internet service = [tex]35 \times \frac{1}{5}[/tex]
Number of houses AT&T providers Internet service = 7
Number of houses Spectrum providers Internet service = [tex]35 \times \frac{2}{7}[/tex]
Number of houses Spectrum providers Internet service = 10
Total number of houses use hotspot = 35 - 7 - 10
Total number of houses use hotspot = 18 houses

Examine the graphs. Determine whether each function is discrete, continuous, or neither discrete nor continuous. Then state the domain and range of each function.
Answers
Hey there! I'm happy to help!
Discrete data are data that are usually counted and are represented by points that are not connected by a line.
Continuous data are data that are represented by a straight line.
Our graph has a continuous function because it is made of continuous.
In a function, the domain is all of the x-values and the range is all of the y-values.
With discrete data, the domain and range are usually more finite, and with continuous data, it is usually infinite.
What x-values on this graph include any possible number. If we follow the arrow on the bottom left side of our line, it will go down forever and go in the direction of infinitely many negative x-values. The same goes for the other direction with the other side of our arrow.
So, our domain is going to be -∞ ≤ x ≤ ∞.
If we look at our range, we have the same thing happening. We will have infinite negative y-values and infinitely positive as our arrow goes infinitely in both directions.
So, our range is going to be -∞ ≤ y ≤ ∞.
