Answer:
115° and 245°
Step-by-step explanation:
Given
cos x = - 0.4226
Since cos x < 0 then x is an angle in the second / third quadrants, thus
x = (0.4226) = 65° ← related acute angle , thus
x = 180° - 65° = 115° ← angle in second quadrant
x = 180° + 65° = 245° ← angle in third quadrant
The second one since the lowest y value is -4 and the values go forever up
Answer:

Step-by-step explanation:
1) Regroup terms.

2) Use product rule.

3) Simplify 2 × 2 to 4.

Therefor, the answer is p⁴x
Answer :
Let the first term of both the terms be
and last term be 
Now, by using the mid point formula to find the mid point of the segment -

Now, by substituting the values of both x and y -

Adding -7 and 6 -

Now, move the negative in front of the fraction -
