Answer:
Step-by-step explanation:
- We must prove that : sin²∝ + sin²∝ × tan²∝ = tan²∝
- sin²∝+ sin²∝× tan²∝ = sin²∝(1+tan²∝)
- 1+ tan²∝= 1/cos²∝
- So: sin²∝(1+tan²∝)= sin²∝/cos²∝ =tan²∝
Answer:
729 m³
Step-by-step explanation:
Volume of a cube (or a rectangular prism) formula:
lwh
l is length
w is width
h is height
Here, the length, width, and height measures 9 m.
So
9 × 9 × 9 or 9³ = 729
ANSWER
Or
EXPLANATION
Let us find the gradient of the line:
by rewriting it in the slope intercept form.
We divide through by 4 now;
This is now in the form;
where
is he slope.
This implies that the slope of the line that is perpendicular to this line will be the negative reciprocal of .
Thus the perpendicular line has slope,
.
Let the perpendicular line have equation,
When we substitute the slope we have;
We substitute the point. 
to find c.
We substitute c to obtain;

The paid amount including service fee, tip, and tax is $77.987.
<h3>what is the percentage?</h3>
the percentage is value per hundred.
bill value = $59.99
service fee = 3% of $59.99 = 59.99*3/100 = $1.7997
tip = 20% of 59.99 = $11.998
tax = 7 % of $59.99 = $4.1993
total payment = 59.99+1.7997+11.998+4.1993 = $77.987
therefore, the paid amount including service fee, tip, and tax is $77.987.
