Answer:
<h3>34.61</h3>
Step-by-step explanation:
Find the diagram attached
From the diagram;
Hypotenuse = 81.9
Angle of elevation = 65degrees
Required
The value of x (Adjacent)
Using the SOH CAH TOA identity
cos theta = adjacent/Hypotenuse
cos 65 = x/81.9
x = 81.9cos65
x = 81.9(0.4226)
x = 34.61
Hence the value of x to the nearest hundredth is 34.61
Width of a watch can be measured in cms or inches, since it's too small. Distance to the moon is measured in light years, since it is too large. Length of your finger is measures in cms or inches, since it is too small. The length if a roller skating ring is rightly measured in yards, since it is just the right size. It can also be measured in feet.
We have that
y=x²<span>+3x-5
</span>y=4x+1
using a graph tool
see the attached figure
the solution are the points
(-2,-7)
(3,13)
<span>the solution obtained by the student
</span>(-2,0)
(3,0)<span>
is incorrect because the values of the coordinate y are incorrect
</span>the values of x are correct
x1=-2
x2=3
<span>with those values of x obtained, the student had to substitute it in any of the two equations to obtain the value of y
</span>so
for x=3
y=4x+1------> 4*(3)+1-----> y=13
for x=-2
y=4x+1------> 4*(-2)+1-----> y=-7
