Square root of 64+49-2(8)(7)cos32

Mathematics
1 answer:
gizmo_the_mogwai [7]3 years ago

Answer:

+4.245

Step-by-step explanation:

Before you can find the square root of x^2, you have to EVALUATE

64+49-2(8)(7)cos32, and THEN take the square root of the result:

64+49-2(8)(7)cos32 = 64 + 49 - 112(0.848) =  113 - 94.981 = 18.019

Then x^2 = 18.019.

Find the square root of 18.019:  It is +4.245.  A negative result here would make no sense.

write a slope intercept equation for a line passing through the point (2,-2) that is parallel and perpendicular to the line x=-1
vekshin1

You would need two different lines to complete this as lines cannot be both parallel and perpendicular (these are opposites). The answers would be:

Parallel: x = 2

Perpendicular: y = -2

In order to find these, we first need to see that the original line of x = -1 is a horizontal line. Therefore, any line that is parallel should be horizontal as well. To get a horizontal line through the point (2, -2), the only option is x = 2.

Similarly, with the perpendicular line, if the original line is horizontal, the new line must be vertical. The only vertical line that goes through (2, -2) is y = -2.
