What is the value of "c" in the quadratic equation 3x^2 5x 7 = 0?

mote1985 [20]

If you would like to know the value of 'c' in the quadratic equation, you can find this using the following steps:

3x^2 + 5x + 7 = 0

ax^2 + bx + c = 0<span>
a = 3
b = 5
c = 7

The correct result would be 7.</span>

Use subtraction to find the lengths of segments WX and XY.

Point W is on (9,3), point X is on (5,3) and point Y is on (5,9), if I'm reading this correctly.

Point W and point X match with their y-values, so we ignore them. Subtract the x-values, 9 and 5, to get the length. In this case, the length is 4 units.

Point X and point Y match with their x-values, so we ignore them. Subtract the y-values, 3 and 9, to get 6.

Since the problem is asking for length, you always subtract the smaller number from the larger one, as you can't have a negative distance or length.

The solid shape is a cone and a half sphere. So the equation would be (cone volume) + (1/2 sphere volume):
$cone = \frac{1}{3} \pi {r}^{2} h \\ sphere = \frac{4}{3} \pi {r}^{3} \\ object = ( \frac{1}{3} \pi {r}^{2} h) + \frac{1}{2} ( \frac{4}{3} \pi {r}^{3} )$
If the volume of the cone is 270pi and the height of the cone is 10, then:
$270\pi = \frac{1}{3} \pi {r}^{2} (10) \\ 27 = \frac{1}{3} {r}^{2} \\ 80 = {r}^{2} \\ r = 9$
The radius of the object is 9 cm. Therefore, we can plug into the formula for the total volume:
$object = 270\pi + \frac{1}{2} ( \frac{4}{3} \pi {(9)}^{3} ) \\ = 270\pi + \frac{2}{3} (729\pi) \\ = 270\pi \: + 243\pi \\ = 513\pi$
The total volume is 513 pi cm^3
