Answer:
Step-by-step explanation:
The general form of a quadratic equation is often written as ...
ax² +bx +c = 0
The references to "a", "b", and "c" are to the coefficients in this form. Comparing this to your equation ...
x²-3x -2 = 0
we see that the coefficient of x², is 1, so a=1; the coefficient of x is -3, so b=-3, and the constant is -2, so c=-2.
$17.85 is 110% of the original price.
To find 1% divide this by 110:
17.85/110 = 0.16% (rounded).
Original price is 100% so 0.16*100 = $16.23 (rounded).
Check:
$16.23*1.1=$17.85 (1.1 is decimal equivalent of 110%).
I am pretty sure the first thing we should do is to <span>integrate acceleration into velocity
And we will have: </span>


Then calculate v :

As you can see, velocity is zero and none of the objects is moving. It happens when <span> t=7/3 which means we can calculate this in the way we did (integrating) :
</span>

The product is <span>p(0) = 0 that makes us to reduce vector function to</span>

Answer: x= -21
Step-by-step explanation:
-4x=86-2
calculate
-4x=84
divide both sides
x=-21
A and b are the legs, and c is the hypotenuse.
hope this helps!
