In an electrical circuit, the current is related to the power and resistance according to the rule I=pR−−√, where I represents t

he current (measured in amps), P represents power (measured in watts), and R represents resistance (measured in ohms). What is the electrical power drawn by a device that has a resistance of 15 ohms with a current of 4 amps?

Answer:

P=0.27\,\,watts

Step-by-step explanation:

Consider the formula: I=PR

Here, I represents the current (measured in amps), P represents power (measured in watts), and R represents resistance (measured in ohms).

Resistance = 15 ohms

Current = 4 amps

To find electrical power drawn by a device, put R=15\,,\,I=4

So,

4=15P\\P=\frac{4}{15}=0.27\,\,watts

The expression √93 is in between two whole numbers. Write the two numbers with a comma and a space in between
nalin [4]

Answer:

9, 10

Step-by-step explanation:

square root of √93 is 9.64.

Thus, we see that the number 9.64 is greater than  but less than 10.

On number line it can be represented as

-∞ _____________7___8___9__9.64___10___11_______+∞

Thus, we see that  the two whole numbers between which √93 lies is 9, 10

Projectile Is shot upward from the surface of Earth with an initial velocity of 136 meters per second. Use the position
Anna007 [38]

Answer:

v(3\,s) = 106.6\,\frac{ft}{s}, v(15\,s) = -11\,\frac{ft}{s}

Step-by-step explanation:

The velocity function of the projectile is obtained by deriving the position function:

v(t) = -9.8\cdot t + 136

Now, the velocities after 3 and 15 seconds are, respectively:

v(3\,s) = -9.8\cdot (3) + 136

v(3\,s) = 106.6\,\frac{ft}{s}

v(15\,s) = -9.8\cdot (15) + 136

v(15\,s) = -11\,\frac{ft}{s}

F(x)= x^2– 3x + 9<br> g(x) = 3x^3+ 2x^2– 4x – 9<br> Find (f - g)(x).
denis-greek [22]

Answer:

\large \boxed{\sf \ \ -3x^3-x^2+x+18 \ \ }

Step-by-step explanation:

Hello, please consider the following.

(f-g)(x)=f(x)-g(x)=x^2-3x+9-(3x^3+2x^2-4x-9)\\\\=x^2-3x+9-3x^3-2x^2+4x+9\\\\=\boxed{-3x^3-x^2+x+18}

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

The table below shows the relative frequencies of the color of cars bought last month by males and females. Which percentage rep
Pani-rosa [81]
The first thing we must do for this case is to observe the highest relative frequency of the table in the total column.
 For the white car we have:
 Male = 0.11
 Female = 0.20
 Total = 0.31
 The percentage is given by:
 (0.31) * (100) = 31%
 Answer:
 
The percentage that represents the car bought most often is:
 
31%

Please explain how you got your answer (:
melisa1 [442]
I used math

anyway
remember you can do anything to an equation as long as you do it to both sides

so

4n+2 and 1/2=2n+5
minus 2n both sides
4n-2n+2 and 1/2=2n-2n+5
2n+2 and 1/2=0+5
2n+2 and 1/2=5
minus 2 and 1/2 both sides
2n=2 and 1/2
divide both sides by 2
I mean times both sides by 1/2
n=1 and 1/4

answer is C
