HELP!!!!! Find the number of solutions of the equation 5t2 + 3t − 7 = 0 by using the discriminant.
Charra [1.4K]

Answer:

Below in BOLD.

Step-by-step explanation:

1.  The discriminant D = b^2 - 4ac

= 3^2 - 4*5*(-7)

= 9 + 140

= 149.

Positive value so it has 2 real solutions.

2. D = (-12)^2 - 4 * 9 * 4

= 144 - 144

= 0.

So it has one real solution.

3.  D =  2^2 - 4*1*3

= -8.

It is negative so there are No real solutions.

4.  D = 4^2 - 4*2*10 = 16 - 80 = -64.

No solutions.

5. D = (-12)^2 - 4*3*(12)

= 144 - 144 = 0

So its the second choice.

3. What is the radius of the figure if the Area of the Sector is 288*pi? *
Alla [95]

Answer:

The radius of the circle is 36

x = 36

Step-by-step explanation:

Area of sector formula is:

A=\frac{\theta}{360}*\pi r^2

Given  \theta=80, and area (A) is 288\pi, we substitute and solve for r:

A=\frac{\theta}{360}*\pi r^2\\288\pi=\frac{80}{360}*\pi r^2\\288\pi=\frac{2}{9}*\pi r^2\\288\pi=\frac{2\pi r^2}{9}\\2\pi r^2= 2592 \pi \\r^2= 1296\\r=\sqrt{1296}\\r=36

Thus,

The radius of the circle is 36

x = 36
