Write the equation of line perpendicular to y = 4 that passes through (5, 2).

Mathematics

NNADVOKAT [17]3 years ago
4 0
Answer:
x=5

Explanation;
y=4 is a horizontal line, and we know this because all we have is the y intercept; 4 (the y-intercept is the point on the line that intercepts the y axis) There is also no x value. This is the equation for a horizontal line:

y=b
B is the y-intercept.

A line perpendicular to a horizontal line would be a vertical line. This is the equation for a vertical line:

x=d
D is the x-intercept (the point on the line that intercepts the x axis)

So to answer the question, we just need to plug the x value of the point (5,2) into x=d.

(5,2)-> 5 is the x coordinate

Therefore, x=5

I hope this helps! Please comment if you have any questions.

In Wellington, a city of 360,000 citizens, there has been an outbreak of vampires and werewolves There are 3,000 people infected
Alex17521 [72]

Answer:

0.0286 or 2.86%

Step-by-step explanation:

The total number of people that have werewolfism is 21,000.

Of those 21,000, 600 also have vampirism, while the remaining 20,400 do not. Therefore, the probability that someone has vampirism, given that they have werewolfism is:

P(V|W)=\frac{N_{V\cap W}}{N_W}\\P(V|W)=\frac{600}{21,000} \\P(V|W)=0.0286=2.86\%

The probability is 0.0286 or 2.86%.

Find the area of the triangle (but identify which formula to use). Please help!
GalinKa [24]
A.) A= (1/2)absinC
b.) sinA/a, sinB/b, sinC/c
sin100/42, sin25/b, sinC/c
use these two fractions.
sin100/42= sin25/b
cross multiply next
b×sin100= 42×sin25
then divide on both sides by sin100
b=18
c.)measurementofA+measurementofB+measurementofC=180
100+25+C=180
125+C=180
-125 -125
The measurement of angle C is 55 degrees.
d.)A=(1/2)42×18×sin55
= 21×18×sin55
A =309.6 units squared
