It’s A I think but I could be wrong
The problem is stated incorrectly. It should be 7 DAYS and NOT years.
ending amount = beginning amount * (1.8)^days
7 years = 2,555 days
ending amount = 30 * 1.8^7
ending amount = 30 *

or 1,837 (rounded)
answer is D.
The formula for the circumference of a circle 'pi x diameter' so you need to multiply the radius shown on the circle by 2 so 15 x 2 = 30 and then you multiply this by pi using the formula: pi x 30 = 94.25 to 2 decimal places. This is the final answer. The pi symbol is π can be found on an advanced calculator :) .
Answer:
7)
8)
Step-by-step explanation:
7) The equation of the straight line passing through the ordered pair (-3,5) and (3,-5) is given by
⇒ -3(y - 5) = 5(x + 3)
⇒ -3y + 15 = 5x + 15
⇒ 5x + 3y = 0
⇒ (Answer)
8) The equation of the straight line passing through the ordered pair (5,7) and (11,16) is given by
⇒ 2(y - 7) = 3(x - 5)
⇒ 2y - 14 = 3x - 15
⇒ 3x - 2y - 1 = 0
⇒ (Answer)
multiply both sides by -3 , -6*-3 equals 18.
d is less than or equal to 18
