Answer:
18
Step-by-step explanation:
Answer:
174 feet below sea level
Step-by-step explanation:
y is the number of minutes so you can multiply 14 by 9
14*9 is 126
then you add 126 to -300
126 + (-300) is essentially 126 - 300 and that is -174
the submarine was at 174 feet below sea level
Answer:
2,016.4
Step-by-step explanation:
Answer:
Reflected about the y-axis and then rotated 90° counterclockwise
Step-by-step explanation:
(x , y) to (-x , y) --> reflected over y-axis
then (-x , y) --> (-y, -x) -->90 degrees rotation counterclockwise
So answer is the last one
Reflected about the y-axis and then rotated 90° counterclockwise
The equation for the line passing through point A and perpendicular to AB will be y-0.5x=6, the gradient of line AB is -2, and the gradient of a line perpendicular to AB is 0.5.
<h3 /><h3>What is the slope or gradient?</h3>
A numerical assessment of a line's angle relative to the ground is known as the slope.
Given data;
m₁ is the slope of line AB
m₂ is the slope of a line perpendicular to AB
The coordinate points are,
A,(x₁,y₁)= (0, 6)
B,(x₂,y₂)=(3, 0).
The gradient of line AB;
The slope of the lines has a perpendicular relation is -1;
m₁ × m₂ = -1
(-2) × m₂ = -1
m₂ = 1/2
m₂ = 0.5
The equation of the line passing through point A and perpendicular to AB;
(y - y₁) = m₂(x-x₁)
(y-6)=0.5(x-0)
y-6 = 0.5 x
y-0.5x=6
Hence, the gradient of line AB, the gradient of a line perpendicular to AB, and the equation of the line passing through point A and perpendicular to AB will be -2,0.5 and y-0.5x=6.
