The answer is D.
Hopefully this helps! :)
Answer:
The Answer is A. 1.4 x 10^5
Step-by-step explanation:
Numbers in Scientific notation have the first number between 1 and 9 and then the decimal, followed by the rest of the numbers. Find the power of 10 by moving the decimal one place a time from right to left until the decimal is between the last number and the next to last.
B. is wrong because the number is .32 x 10^3 instead of 3.2 x 10^2
C. is wrong because it is 2 to the 10th power (2^10) instead of a power of 10
D is wrong because the number is 11.2 x 10^1 instead of 1.12 x 10^2
Hope this helps!! Have an Awesome Day!! :-)
Answer:
standard form is 45x -12y -100 = 0.
Step-by-step explanation:
Given the equation is -3/2x=-2/5y-10/3.
Finding common denominator, L.C.M.(2,5,3) = 30.
Multiplying both sides by 30.
30*(-3/2x) = 30*(-2/5y-10/3)
-45x = -12y -100
Moving all terms on left side, keeping right side equal to 0.
-45x +12y +100 = 0
Making x's coefficient positive by changing all signs.
45x -12y -100 = 0
Hence, standard form is 45x -12y -100 = 0.
y -y1= m(x-x1) is in point slope form
y --9 = -2 (x-10)
y+9 = -2(x-10)
Answer:
£1,219.5
Step-by-step explanation
Original price of car = £4500,
If the car depreciates by 10% after first year
New price = 90% of 4500
New price = 0.9 * 4500
New price = £4050
Second year
Price = 90% of 4050
Price = 0.9 * 4050
Price = £3,645
Third year:
Price = 90% * £3,645
Price = 0.9 * £3,645
Price = £3,280.5
Decrease in value = £4500 - £3,280.5 = 1,219.5
Hence the value of the car would have decrease by £1,219.5 after 3 years
