Answer:
c) 5
Step-by-step explanation:
In this question you are being asked to find the hypotenuse of the triangle
the triangle has one side that is 3 and the other is 4
use Pythagoras to find the missing side (a^2+b^2=c^2)
3^2+4^2=c^2
simplify the exponents
9+16=c^2
combine like terms/adding
25=c^2
take the square root
5=c
the length of the hypotenuse is 5
Step-by-step explanation:
3/7y + 3/4x = 3/5
y = -3/4x.7/3 +3/5.7/3
y = -7/4x +7/5
so the slope is -7/4
Answer:
Step-by-step explanation:
- The first question's slope is 0 because it is a straight horizontal line
- The second question is undefined because it is a straight vertical line
- The third question's slope isn't able to be found with a blank line, but the line is positive because the more it travels right, it also goes up. So the slope of the third is positive
- The fourth is similar to the third as its slope cannot be calculated with a blank line, but the more it moves right, the more it moves down, meaning the slope is negative.
Cos theta = base /perp
= sqrt(13)/7
=0.515
