What are the values of a, b, and c in the quadratic equation 0 = = x2 – 3x – 2?<br> a=1 h=30-2
jek_recluse [69]

Answer:

  • a = 1
  • b = -3
  • c = -2

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.

A store sold a case of scented candles for $17.85 that had been marked up 110%. What was the original price?
Salsk061 [2.6K]

$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%).

An object, which is at the origin at time t=0, has initial velocity V0= (-14.0i - 7.0j)m/s and constant acceleration a=(6.0i + 3
sesenic [268]
I am pretty sure the first thing we should do is to <span>integrate acceleration into velocity
And we will have: </span>a(t) = \ \textless \ 6,3\ \textgreater \v(t) = \ \textless \ (6t+C),(3t+C)\ \textgreater \ ; where    -- v(0) = \ \textless \ -14,-7\ \textgreater \
Then calculate v :&#10;v(t) = \ \textless \ (6t-14),(3t-7)\ \textgreater \
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>p(t) = \ \textless \  (3t^2-14t+C) , ((3/2)t^2-7t+C) \ \textgreater \ &#10;
The product is <span>p(0) = 0 that makes us to reduce vector function to</span>p(t) = \ \textless \  (3t^2-14t) , ((3/2)t^2-7t) \ \textgreater \   where t = 7/3p(7/3) = \ \textless \  -49/3 , -49/6 \ \textgreater \<span>
