What would be the x values for 3x^2-10x +7 = 0?

1 answer:

8 0

The answers are x = 2.33 and x=1

3x^2 - 10x + 7 = 0
x3

x^2 - 10x + 21 = 0

After you find the factors, you divide them by 3, since you multiplied by 3 before.

(x - 7/3) (x - 3/3)

Simplify.

(x - 2.33) (x - 1)

Equal both to zero and solve.

(x - 2.33) = 0

(x - 1) = 0

x = 2.33
x = 1

Determine the midpoint between the two points x(4,-6) and y(-2,8)

ikadub [295]

Answer:

$p(a, b) = (1, 1)$

Step-by-step explanation:

Midpoint formula is

$p(a, b)=(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} )$ ---------------(1)

Here

$(x_1, y_1) = (4, -6) \ \ \ and \ \ \ (x_2, y_2) = (-2, 8)$

Substituting values in equation (1)

$p(a, b)=(\frac{4 - 2}{2}, \frac{-6 + 8}{2} )$

$p(a, b) = (1, 1)$

How many cubic centimeters of water can this paper cone cup hold?

blagie [28]

48π cm^3

Step-by-step explanation:

The formula for the volume of a cone is...

$V=\frac{1}{3}\pi r^2h$

We can plug everything we know from the photo into the equation, but note that the picture gives us the diameter, which is 8, instead of the radius. The radius is half of the diameter, so the radius will be 4. Also we will be leaving pi as it is, instead of changing it to 3.14.

$V=\frac{1}{3}*(\pi *4*4*9)$
