Answer:
is there just 2 answers too this question? anyways the answer b
Answer:
25.8 ft
Step-by-step explanation:
Draw a right triangle with the right angle at the foot of the tower. The interior angle of the triangle at the top is the complement of the angle of depression. 90 - 74 = 16; it measures 16°. The leg at the bottom has length x. The height of the tower is the vertical leg and is 90 ft. We are looking for x.
For the 16° angle, x is the opposite leg, and 90 ft is the adjacent leg.
tan A = opp/adj
tan 16° = x/(90 ft)
x = 90 ft * tan 16°
x = 25.8 ft
Answer: 25.8 ft
Answer:
C
Step-by-step explanation:
We want to simplify the rational expression:
First, we can factor both the numerator and the denominator. This yields:
Cancel like terms:
However, since we canceled a term from our expression, we must place restrictions in order to stay true to the original expression.
Rational expressions are undefined whenever the denominator equals 0. The denominator is (before canceling):
Solve for n. By the zero product property:
Therefore:
By taking the square root of both sides (since we are taking an even root, it is required to have plus/minus):
Therefore, our fully simplified expression is:
Hence, our answer is C!
Answer:
So option b is right.
Step-by-step explanation:
Given that a figure is located in Quadrant I.
The figure is transformed and the image is located in quadrant iv.
We have to select the option which would have resulted in this.
A) rotating 360 degrees would result in the same place i.e. I quadrant hence wrong.
B) rotating 180 degrees counterclockwise, will make y coordinate negative but x coordinate will remain as it is.
Hence we get image in the IV quadrant.
THis option is correct
C) Rotating90 degrees counterclockwise will not transform all the coordinates to the IV quadrant hence wrong
D) Rotating 270 degrees counterclockwise would make the image in III quadrant hence wrong
So option b is right.
Answer:
The graph of y2+3x=0 is symmetric with respect to the x-axis
Step-by-step explanation:
To establish symmetry with respect to the x-axis we simply substitute -y in place of y in the original equation. If the resulting equation is identical to the original one then the function is said to be symmetric with respect to the x-axis.
In this case we have;
Which is identical to the original equation
