The answer is B) 1.9 you need to use Pythagoras where a^2+b^2=c^2, so at 9 o'clock it will make a right angle triangle so the square root of 1.5^2+1.2^2 is 1.92093... rounded it is 1.9
R>Q
Because it's a greater amount
Exact form: 1/45
Decimal: 0.02
Answer:
The price increases by 5439 dollars.
The price of the next model is 42439 dollars.
Step-by-step explanation:
The next model of sports car will cost 14.7% more so it will be 114.7% of the current model. Therefore you multiply
37000 * 1.147 = 42439
To find out how much it increases by, you find the difference between the two prices which is 5439 dollars.
Hope this helped!!
Answer:
<h3>
f(x) = -x² + 20x - 96</h3>
Step-by-step explanation:
Parabola f(x) = ax² + bx + c passing through points (8,0) and (12,0) means that 8 and 12 are its root and (x-8) and (x-12) are its factors
So we get:
f(x) = a(x - 8)(x - 12)
The parabola passes through point (13, -5) that means if x=13 then f(x)=-5
So:
-5 = a(13 - 8)(13 - 12)
-5 = a(5)(1)
-5 = 5a
a = -1 {<0 so parabola opens down}
Therefore:
f(x) = -(x - 8)(x - 12)
And expanding:
f(x) = -(x² - 12x - 8x + 96)
So the standard form equation of the parabola:
<u>f(x) = -x² + 20x - 96</u>
