Answer:
3.186 x 10^8
Step-by-step explanation:
3.2× 10^8 = 320,000,000
1.4 × 10^6 = 1,400,000
320,000,000 - 1,400,000 = 318,600,000
318,600,000 = 3.186 x 10^8
- you get to the power of eight, by counting the amount of spaces the decimal moved over (moving to the left increase, but right decreases)
Answer:
y - 3 = - 4 ( x + 4)
Step-by-step explanation:
(-4,-3) and (4,1)
Slope = (1 + 3)/(4 + 4) = 2/8 = 1/4
Perpendicular lines, slope is opposite and reciprocal so slope of the line that is perpendicular to the given line is -4
Equation in point slope form, passing thru (-4 , 3)
y - 3 = - 4 ( x + 4)
Answer:
Total amount of fuel =200,000 litres
Amount of fuel used = 130,000 litres
Percentage of the fuel capacity used:
<em><u>65%</u></em> of the fuel is used on this flight.
Your answer is 35.75%.
Let’s pretend something at the store is $100. (It will save some math later)
100 - 35% leaves 65% (0.65 as a decimal)
100 x 0.65 = 65
That’s the price after the first discount. If we take 45% off of the sale price, we’ll be left with 55%, 0.55
65 x 0.55 = $35.75
Now normally you’d compare 35.75(sale price)/ 100(original price) to % off (x)/100, but doe this example, it’s unnecessary.
35.75/100 = x%/100
Answer:
1. f (2) = 3 x 2^x-1
2. f (-1) = -3 x 2^x
