Answer with explanation:
The equation of any line with slope 'm' and passing through any point
is given by

As we know that the general equation of a line with slope 'm' is 
Comparing with the given equation
we can conclude slope of the given line is 
Now we know that the product of slopes of perpendicular lines is -1
Mathematically we can write for perpendicular lines

Thus the slope of the required line is obtained from the above relation since it is given that they are perpendicular

Hence using the given and the obtained values the equation of the required line is

Part b)
The angle of intersection between 2 lines with slopes
is given by

Comparing the equations of given lines

with the standard equation we get

Thus the angle of intersection becomes

60% more than regular size. 230.4.
Answer:
D) 252.00
Step-by-step explanation:
Initial price of computer = $400
Less 30 % = -0.30 × 400 = - 120
Sale price = 280
Less 10 % = -0.10 × 280 = -28
Final price = $252
Answer:
sqrt 52
Step-by-step explanation:
use the pythagorean thereom
side a - 4
side b - 6
to find the hypotenuse, simply square both sides.
4² + 6²
4 x 4 = 16
6 x 6 = 36
add these two together
you should get 52.
After finding the combined side length, find the inverse operation of squared.
The inverse operation is the square root.
So find the square root of 52.
√52 = 7.21110255
round to the nearest tenth.
the answer should be 7.2
But to keep it in radical form the answer is sqrt 52
