The answer is 1/3 and the second box is -1/3
The quadratic formula, has a part we call the "discriminant" defined by the variables that are inside the square root, and is denotated by "delta":
<span>Δ=<span>b2</span>−4ac</span>
Whenever we solve a quadratic equation that is complete and we analyze the discriminant, we can get 3 scenarios:
<span>if→Δ>0<span>=></span>∃<span>x1</span>,<span>x2</span>/a<span>x2</span>+bx+c=0</span>
This just means: "if the discriminant is greater than zero, there will exist two x-intercepts"
And for the second scenario:
<span>if→Δ=0→∃<span>xo</span>/a<span>x2</span>+bx+c=0</span>
This means: "if the discriminant is equal to zero, there will be one and only one x-intercept"
And for the last scenario:
<span>if→Δ<0→∃x∉R/a<span>x2</span>+bx+c=0</span>
This means that :"if the discriminant is less than zero, there will be no x-intercepts"
So, if we take your excercise and analyze the the discriminant:
<span>3<span>x2</span>+7x+m=y</span>
we will find the values that satisfy y=0 :
<span>3<span>x2</span>+7x+m=0</span>
And we'll analyze the discriminant:
<span>Δ=<span>72</span>−4(3)(m)</span>
And we are only interested in the values that make the discriminant equal zero:
<span><span>72</span>−4(3)(m)=0</span>
All you have to do is solve for "m".
Lateral Area of cone=1130.4 inches^2
Step-by-step explanation:
Diameter of circular base = 18 inches
Height of cone = 40 inches
Lateral Area of cone = ?
The formula used to find Lateral Area of cone is:

Since we know that r= d/2,
so, r = 18/2
r= 9
Putting values, we get:

So, Lateral Area of cone=1130.4 inches^2

<h3><u>QU</u><u>ESTION</u><u>:</u><u>-</u></h3>
<u>Fin</u>d 26th term of the A.P --15,-35,-55,-75...
<h3><u>Solu</u><u>tion</u><u>:</u><u>-</u></h3>
First term=a=-15
Common Difference=d=-20
We know that






the first step is to isolate A which gets 39.59a+45=44.99
now get A and only A
39.59a=-.1
now divide both sides by 39.59 getting A= -0.00252589
