Which two charges have a sum of 0? (1 point) a +6 charge and +6 charge b −6 charge and −6 charge c +6 charge and 0 charge d +6 c

Roman55 [17]

Answer:

+6 charge and −6 charge

Step-by-step explanation:

In this problem, we need to find two charges that have a sum of 0.

In option (d), both charges have the same magnitude. But they have opposite charges.

Sum means to add up charges i.e.

+6 charge +(-6) charge = 0 (they have opposite charges)

Hence, the correct option is (d).

The function y = -2(x-3)^2+4 shows the daily profit (in hundreds of dollars) of a hot dog stand, where x ist the price of a hot

Blababa [14]

Answer:

Option A The zeros are the hot dog prices that give $0.00 profit (no profit)

Option C. Zeros at $x=3(+/-)\sqrt{2}$

Step-by-step explanation:

we know that

The zeros of the function are the values of x when the value of y is equal to zero

In this problem

The zeros of the function are the price of a hot dog (in dollars) when the daily profit (in hundreds of dollars) of a hot dog stand are zero

we have

$y=-2(x-3)^{2}+4$

Find the zeros

equate the equation to zero

$0=-2(x-3)^{2}+4$

$2(x-3)^{2}=4$

$(x-3)^{2}=2$

square root both sides

$x-3=(+/-)\sqrt{2}$

$x=3(+/-)\sqrt{2}$

If $1000 is invested in an account earning 3% compounded monthly, how long will it take the account to grow in value to $1500? R

My name is Ann [436]

Answer:

14 months

Step-by-step explanation:

1 month) 1.03(1000) = 1030

2 months) 1030(1.03) = 1060.9

3 months) 1060.9(1.03) = 1092.727

4 months) 1092.727(1.03) = 1125.50881

5 months) 1125.50881(1.03) = 1159.2740743

6 months) 1159.2740743(1.03) = 1194.05229653

7 months) 1194.05229653(1.03) = 1229.87386542

8 months) 1229.87386542(1.03) = 1266.77008139

9 months) 1266.77008139(1.03) = 1304.77318383

10 months) 1304.77318383(1.03) = 1370.01184302

11 months) 1370.01184302(1.03) = 1411.11219831

12 months) 1411.11219831(1.03) = 1453.44556426

13 months) 1453.44556426(1.03) = 1497.04893119

14 months) 1497.04893119(1.03) = 1541.96039912

I multiplied them all by 1.03 because 0.03 is 3% but if I multiplied the numbers by 0.03 it would give me 3% of that number instead of increasing it by 3% so by doing 1.03 x the number I am adding the 3% onto the number

Why do you get a math error when you try to evaluate (-100) ^0.5, but not when you evaluate -100^1.5?

6+n/5=9<br><br> What is happening to the variable? <br><br><br> How do you solve for the variable?

Svetradugi [14.3K]

Answer:

n=15

Step-by-step explanation:

(subtract 6 from both sides of the equation.)

6+n/5=9

6+n/5-6=9-6

(Now you will have to simplify.)

n/5=3

(You will have to multiply all terms by the same value to eliminate fraction denominators.)

n/5=3

5xn/5=5x3

(You will now have to simplify.)

n=15

And that's how you get your answer.

i hope this helps. :)
