3. Congruent, 30 degrees
4. 2x+30+50=180
80+2x=180
x=50
2x=100
5. 3x-13+58=90, so 3x+45=90
3x=45 x=15
3x-13=3(15)-13
=45-13
=32 degrees
2 + 13x, because (19x − 6x) + 2 = 13x + 2 = 2 + 13x
The vertex of a parabola is the point where the parabola crosses its axis of symmetry.
For this case we have that the vertex of the parabola is the point:
(x, y) = (1, 4)
Equivalently:
x = 1
y = 4
answer:
the vertex of the graph shown below is
(x, y) = (1, 4)
Answer: The investment will be 6314 after 9 years.
Step-by-step explanation:
Formula to calculate the accumulated amount in t years:
, whereP= principal amount, r= rate of interest ( in decimal)
Given: P = $4,625
r= 3.52% = 0.0352
t= 9 years
Then, the accumulated amount after 9 years would be:

Hence, the investment will be 6314 after 9 years.
