The hurdle and runner form a right triangle (see attached picture) such that
sin(30°) = <em>h</em> / (5 ft)
and
cos(30°) = <em>x</em> / (5 ft)
where <em>h</em> is the height of the hurdle and <em>x</em> is the horizontal distance from where the runner jumps to the hurdle. So
<em>h</em> = (5 ft) sin(30°) = 5/2 ft = 2.5 ft
<em>x</em> = (5 ft) cos(30°) = (5√3)/2 ft ≈ 4.33 ft
Subtract to find the weight she gained since birth.
32 - 8 = 24
Divide to see how many years passed.
24 / 4 = 6
Therefore, Darrel's baby sister is 6 years old.
Best of Luck!
Answer:
the equation of the line will be:
Step-by-step explanation:
Equation of line: x + y = 6
We need to write an equation for the perpendicular line that goes through
(5, 1).
The equation will be in slope-intercept form where m is slope and b is y-intercept
Finding Slope:
Equation of line given is: x+y=6
Writing it in slope-intercept form:
The slope of this line is m = -1 (By comparing it with we get m = -1)
Since the required line is perpendicular, their slopes will be opposite inverse of each other i.e.
So, slope of required line will be: m=1
Now, using the point (5,1) and slope m=1 we can find y-intercept
So, we get y-intercept b = -4
Now, the equation of required line, having slope m=1 and y-intercept b = -4
So, the equation of the line will be:
Answer:
8411?
Step-by-step explanation:
I am not entirely sure because you put an x without any spaces soo I don't know if that supposed to be a variable or multiplication sign. If its a multiplication sign then its 8411 because 36+65=99. 99 x 85=8415. 8415 - 4 = 8411.
