You have shared the situation (problem), except for the directions: What are you supposed to do here? I can only make a educated guesses. See below:
Note that if <span>ax^2+bx+5=0 then it appears that c = 5 (a rational number).
Note that for simplicity's sake, we need to assume that the "two distinct zeros" are real numbers, not imaginary or complex numbers. If this is the case, then the discriminant, b^2 - 4(a)(c), must be positive. Since c = 5,
b^2 - 4(a)(5) > 0, or b^2 - 20a > 0.
Note that if the quadratic has two distinct zeros, which we'll call "d" and "e," then
(x-d) and (x-e) are factors of ax^2 + bx + 5 = 0, and that because of this fact,
- b plus sqrt( b^2 - 20a )
d = ------------------------------------
2a
and
</span> - b minus sqrt( b^2 - 20a )
e = ------------------------------------
2a
Some (or perhaps all) of these facts may help us find the values of "a" and "b." Before going into that, however, I'm asking you to share the rest of the problem statement. What, specificallyi, were you asked to do here?
Si los lados están en razón 1 a 1/2 la medida de los lados del otro rectángulo será la mitad del original.
7×1/2 = 3,5
5×1/2 = 2,5
Dimensiones de la imagen largo 3,5 ancho 2,5. Para comprobar que son proporcionales si divides el largo entre el ancho del primer rectángulo el cociente debes ser igual al que se obtiene al dividir el largo entre el ancho del segundo rectángulo.
7÷5 = 1,4
3,5÷2,5 = 1,4
El valor de cada lado del segundo rectángulo se obtiene multiplicando los lados del primer rectángulo por 1/2
Los ángulos son iguales.
Sí. Todos los rectángulos, por definición tienen 4 ángulos rectos
Todos los rectángulos tienen la misma forma, pueden ser más pequeños o más grandes, pero todos tienen los lados iguales 2 a 2 y 4 ángulos rectos
45.95+12.95+ 6.89= 65.79
I wouldn’t be too trusting of my answer though, haven’t done this math in a while
Answer:
The answer is 90 winners.
Step-by-step explanation:
Well, we are given three days. The first day has a rate of 13% winning. The second day has a rate of 13% as well. And the third day has a rate of 11%. You can find this simply by dividing the amount of winners by amount of participants. Now, we must find the mean, or average, of these statistics. We will get 12% as the average rate of winners. How did we get this? By simply adding all three (13+13+11) then dividing by three (37/3), which gives us 12% if we round to a whole number. Now, we can take this number and get 12% of 750. How do we do this? Well, 12% is equal to 0.12. So we will multiply 0.12 by 750. This will give us 90. And there you have your answer.
<em>Alternatively</em>, you could add up the total amount of contestants from the three days. You should end up with 1000. Then add up the total amount of winners from the three days. You should get 120. Divide both of these by 4. The winners will now be 40, and the total contestants will be 250. Now multiply both by 3. The amount of contestants will be 750, and the amount of winners will be 90. This way is a bit easier, but does not always work. <u>Do what is best for you!</u>
Hope this helped!
