When placed in the box below, what expression will complete an example of the commutative property of addition 7(2+9)= ?
ANEK [815]

The expression for 7(2+9) IS A(B+C) which is distributive property of addition over multiplication.

Only two arithmetic procedures are subject to the commutative property: Multiplication and Addition

 A + B = B + A Which is Commutative property of addition

A.B = B.A, which is a commutative property of multiplication.

Distributive property is A(B+C) =AB+AC

The operation on numbers that are available in brackets can be distributed for each number outside the bracket, according to the distributive property. It is one of the mathematical properties that is used the most. Commutative and associative qualities are the other two important features.

from the given data 7(2+9) =7*2+7*9

                                                =14+63

                                                =77

Now, we can clear that 7(2+9) =7(9+2)

Hence, the expression for commutative property of addition is A(B+C) = AB+AC.

Priscilla invests $10,000 in an account that compounds interest continuously and earns 11%. How long will it take for her money
Shkiper50 [21]

Answer:

Step-by-step explanation:

When the interest compounds continuously, our formula is

A(t)=Pe^{rt}

If we start with 10000 and are looking for how long, t, it takes to double, we are looking for how long it will take for our account to have 2 times 10000.  That's 20000.  Therefore, our equation is

20000=10000e^{.11t}

Divide both sides by 10000 to get

2=e^{.11t}

Take the natural log of both sides to "undo" that e:

ln(2)=ln(e^{.11t})

Again, since ln and e undo each other what we have now is

ln(2) = .11t and

\frac{ln(2)}{.11}=t so

t = 6.3 years

Please help soon!!! Will mark brainliest!!!
BartSMP [9]

REVISED ANSWER.

In the picture, I have drawn on the example given. the RC and PD are the same because They are across from each other perfectly. So the answer is still PD=400m but if there can be two answers then I would have to say another possiblity would be 200m for the diameter of the pond. The wording of this problem is tricky and the picture can throw you off a bit but I did my best to answer properly here.

So if you could mark brainliest that would be awesome.
