The length of a rectangle is 2 more than twice the width. The area of the
vlada-n [284]

Answer: w=5 , L= 2+2(5)=12

Step-by-step explanation:

L=2+2W

A= 60

LxW=60, now we will replace the L

(2+2W)(W)=60   we multiply

2w^2+2w=60

2w^2+2w-60=0  we divide by 2 the equation so we can work easier

w^2+w-30=0

find out w using the quadratic equation

we will get 2 solution,

w=5 and another solution is -6, which is not valid, as the side can not be negative

Find the value of x.<br> X =
Paladinen [302]

Answer:

X = 20

Step-by-step explanation:

when you have an angle that looks like an X shape the angles opposite each other are always equal. knowing this we now know that angle 5x must equal 100

so just make X the subject of the formula and solve, like shown bellow

5x = 100

x = 100 \div 5

x = 20

Help me please I don’t know what to do

To find an inverse function first replace f(x) with y

f(x) = 8*sqrt(x)
y = 8*sqrt(x)

Then, simply switch the places of the x and y.

x = 8sqrt(y)

Now solve for the new y by squaring both sides (to get rid of the root)

x^2 = 64y

divide to get

y = x^2/64. This is the inverse function or option C.

In a parallel circuit, ET = 208 V, R = 33 kΩ, and XL = 82 kΩ. What is the apparent power?
jeka94

Answer:

Apparent power is 1.413Volt-Amps.

Step-by-step explanation:

We are given that in a parallel circuit,E_{T}=208V,R=33kΩ and X_{L}=82kΩ.

And we are asked to find apparent power.

Apparent power is the combination of true power and reactive power.

In other words, we can say that in a power triangle apparent power is the hypotenuse where as true power and reactive powers are sides.

Let us find true power , reactive power first and the using Pythagorean theorem we can find apparent power.

True power=\frac{E_{T}^{2}}{R}=\frac{208^{2}}{33000}=1.311watts

Reactive power=\frac{E_{T}^{2}}{X_{L}}=\frac{208^{2}}{82000}=0.528VARs

Hence apparent power=\sqrt{1.311^{2}+0.528^{2}} =1.413VA
