Refer to the diagram shown below.
The right vertex is at (14, -1), and the center is at (-1, -1).
Therefore the semi-major axis is
a = 14 - (-1) = 15
The right focus is at (8, -1).
Therefore
c = 8 - (-1) = 9.
The distance of the directrix from the center is
d = c²/a = 9²/15 = 81/15 = 27/5.
Therefore the equation for the left directrix is
x = -1 - 27/5 = -32/5
Answer: x = -27/5
Answer:
.25
Step-by-step explanation:
2 eggs are pink
4 eggs are purple
2 eggs are orange
-----------------------
8 total eggs
P( orange) = orange eggs/ total eggs
= 2/8
= 1/4
= .25
Answer:
13.92$
Step-by-step explanation:
13.26 times .05 (sales tax)
.66 + 13.26 = 13.92
• P is the principal amount, $3000.00.
• r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.
• t is the time involved, 8 years time periods.
• So, t is 8 year time periods.
To find the simple interest, we multiply 3000 × 0.06 × 8 to get that:
The interest is: $1440.00
