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.

gogolik [260]

Answer:

There are 3060 apples in the shipment.

Step-by-step explanation:

Given:

Number of boxes of apples = 15

Each boxes contains = 17 bags of Apples

hence 15 boxes will contains = Number of bags of apples in 15 boxes.

By Using Unitary Method we get;

Number of bags of apples in 15 boxes = 15\times 17= 255 \ bags \ of \ apples

Hence 15 boxes contains = 255 bags of apples.

Also Given:

Each bag contains = 12 apples

255 bags contains = Number of apples in 255 bags

By Using Unitary Method we get;

Number of apples in 255 bags = 255\times12= 3060 \ apples

Hence 255 bags of apples contains = 3060 apples.

Hence There are 3060 apples in the shipment.
