Lorico [155]2 years ago
6 0

Answer:

-6125

Step-by-step explanation:

negative 78 squared = -6084

-6084 + 3 - 9 = -6090

-6090 - 5 squared minus 6 minus 4 = --6125

I got confused by "8th" and "a minus" do you mean 3a, and 6a?

Simplify (use only positive exponents) : (3y^10)(2y^2)/8y^5
nadezda [96]
When multiplying variables with exponents, all you have to do is to add the exponents and that’s the ‘product.’

So;

(3y^10)(2y^2) is equal to (3)(2)(y^10+2).

6y^12/8y^5


When dividing exponents, you do the opposite and subtract the exponents. And you divide the whole number by half.


6y^12/8y^5 = 3y^7/4

A hair dryer has a resistance of 11. 5. What current does it conduct when it is plugged into a wall outlet that provides 120 V?
Nata [24]

The current it conduct when it is plugged into a wall outlet that provides 120 V is 10.4A

<h3>Ohms law</h3>

The current passing through a conductor is proportional to the potential difference. Mathematically;

V = IR
where
V is the voltage = 120V

R is the resistance = 11.5 ohms

Required

Current I

Substitute

I = V/R
I = 120/11.5
I = 10.4A

Hence  the current it conduct when it is plugged into a wall outlet that provides 120 V is 10.4A
