7 0

Answer:

\huge\boxed{16}

Step-by-step explanation:

The discriminant of y=ax^2+bx+c is equal b^2-4ac.

We have the equation:

x^2+2x+5=0\to a=1,\ b=2,\ c=5

Substitute:

b^2-4ac=2^2-4(1)(5)=4-20=-16

3. Alexander deposited money into his retirement account that is compounded annually at an interest rate of 7%. Alexander though
Akimi4 [234]
The equation for compound interest is: 


Where r is the interest rate and n is the number of times per year it's applied. Annually n = 1 and 7% interest r = 0.07 The quarterly rate 2% is already quartered 0.02 = r/n . 


You can see that Alexander is incorrect. A quarterly compound interest rate of 2% will accrue more interest than a 7% compound annual interest rate. 


1.7% compound quarterly Hope this helps:)

If the mass of two objects is increased, what is the effect on the force between them?
almond37 [142]

Answer:

A

Step-by-step explanation:

The formula used for this type of question is

F = \frac{Gm_1m_2}{r^2}  

so as long as you don't change anything else (like r), changing m will increase the force. Both of the last 2 answers look like they might be feasible, but they are not. The attraction increases.

So the answer is A

You shuffle a standard 52 card deck of cards, so that any order of the cards is equally likely, than draw 4 cards. How many diff
galina1969 [7]

Answer:

270725 different ways

Step-by-step explanation:

The problem tells us that the order of the letters does not matter. Therefore, in the combination the order is NOT important and is signed as follows:

C (n, r) = n! / r! (n - r)!

We have to n = 52 and r = 4

C (52, 4) = 52! / 4! * (52-4)! = 52! / (4! * 48!) = 270725

Which means that there are 270725 different ways in total to make that raffle
