Can a quadratic equation have more than two solutions?

Answers

A quadratic equation always has exactly two solutions.  If the quadratic
expression is a perfect square, then they're both the same solution.
Quadratic equation can have maximally two solutions if delta>0.

What is the volume of the right prism? A.
166 in3

B.
140 in3

C.
64 in3

D.
16 in3

Answers

I saw the image that should have been included in this problem.

It was a rectangular prism. It can also be identified as a right prism because its bases are aligned one directly above the other and its lateral faces are rectangular.

The image has the following measurements:
length = 7 inches
width = 5 inches
height = 4 inches

volume = length * width * height
v = 7 in * 5 in * 4 in
v = 140 in³  Choice B.

360

for me it was 360.

Simplify the given equation. 5x + 2(x - 3) = -2(x - 1)

Answers

on the left side, distribute the 2 to x and -3 so the left side should look like 5x+2x-6.

on the right, distribute the -2 to x and -1 so the right side should look like -2x+2.

combine like terms on the left to get 7x-6=-2x+2

add -2x from the right side to the left side to make the equation 9x-6=2 now it's a two step equation.
add 6 to 2 to get 9x=8. divide by 9 and x=8/9.


If 8 people share 44 balloons equally, how many balloons does each person get?

Answers

5.5 or either they would all get 4

Answer:

5.5 but to have half a balloon is impossible so we should say 4 just for the case of it

Step-by-step explanation:

We know that there are 8 people and 44 balloons, they want to be shared equally, "equally" is a term for division, so we divide.

44 / 8

==> 5.5

Of course there is no such thing as a half balloon, so if we were to ask how many everyone would get, it would be 4 at most.

Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were allergic to penicillin, Nathan has a 75% chance of having the same allergy. The doctor performed a skin test to see whether Nathan would react to it. The test is 98% accurate. What is the probability that Nathan is not allergic to penicillin and the test predicts it?0.005
0.015
0.245
0.735

Answers

Answer:

Option 3 is correct.

Step-by-step explanation:

Given that Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were allergic to penicillin, Nathan has a 75% chance of having the same allergy. The doctor performed a skin test to see whether Nathan would react to it. The test is 98% accurate.

we have to find  the probability that Nathan is not allergic to penicillin and the test predicts it.

As, Nathan has a 75% chance of having the same allergy.

Hence, (100-75)%=25% chance of not having the same allergy.

Also the test predicts given

Probability that Nathan is not allergic to penicillin and the test predicts it is = 25\%* 98\%

  =0.25* 0.98=0.245

Hence, Option 3 is correct.

0.245 because of him having the 75% chance of getting it and the test only being 98%
