Answer:
The Pythagorean identity states that
Using that we can rewrite the left denominator as:
Which can be factored as
The numerator we can expand as:
On the right hand side, let's multply numerator and denominator with (1 - sin t):
The total formula then becomes:
There you go... left and right are equal.
Answer:
(-2,-110)
Step-by-step explanation:
First solve for x
20x−70=70x+30
x= -2
Now substitute x for -2
y=20x−70
y=20(-2)-70
y = -110
Answer:
Step-by-step explanation:
11
It's 45 because they are congruent. If the vertex is in the center of a circle then the angle and the arc are congruent
4p-7=13
After the first step which is combining like terms, so add the 3p and the single p together.
Next, the negative 7 turns to a positive when we exterminate it from one half of the equation and add it towards the second part.
4p-7=13
+7. +7
4p=20
Divide both sides by 4 to get the p alone.
4p=20
/4. /4
P=5
That is the answer to the entire equation, again though the first step answer is at the very top, i just felt like solving it for you as well.
