What is the resistance of a 1.00X10^2 -Ω , a 2.50-kΩ , and a 4.00-k Ω resistor connected in parallel?

Andreas93 [3]

Answer:

Therefore, the total Resistance: R = 93.9 Ω

Step-by-step explanation:

Given

R₁ = 1 × 10²

R₂ = 2.5 kΩ = 2.5 × 10³ Ω

R₃ = 4 kΩ = 4 × 10³ Ω

Given that the given resisters are connected parallel, so using the formula to calculate the total Resistance R:

$\frac{1}{R}\:=\:\frac{1}{R_1}\:+\:\frac{1}{R_2}+\frac{1}{R_3}$

susbtituting R₁ = 1 × 10², R₂ = 2.5 × 10³ Ω, and R₃ = 4 × 10³ Ω

$\frac{1}{R}=\frac{1}{1\times \:10^2}+\frac{1}{2.5\times \:10^3}+\frac{1}{4\times \:10^3}$

Multiply by LCM of R, 100, 2500, and 4000: 20000 R

$\frac{1}{R}\cdot \:20000R=\frac{1}{1\cdot \:10^2}\cdot \:20000R+\frac{1}{2.5\cdot \:10^3}\cdot \:20000R+\frac{1}{4\cdot \:10^3}\cdot \:20000R$

simplify

$20000=213R$

Switch sides

$213R=20000$

Divide both sides by 213

$\frac{213R}{213}=\frac{20000}{213}$

Simplify

$R=\frac{20000}{213}$

$R = 93.9$ Ω

Therefore, the total Resistance: R = 93.9 Ω

. Joanne does a daily walk from building P to building Q. Given point P(6,9) and point Q(5,-4), what is the distance between poi

kotykmax [81]

Answer:

The distance between points P and Q on this campus map of the local college is 13.038 units

Step-by-step explanation:

We are given that Joanne does a daily walk from building P to building Q

$P=(x_1,y_1)=(6,9)\\Q = (x_2,y_2)=(5,-4)$

We are supposed to find the distance between points P and Q on this campus map of the local college

We will use distance formula :

$d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute the values in the formula .

$d=\sqrt{(5-6)^2+(-4-9)^2}\\d=13.038$

Hence the distance between points P and Q on this campus map of the local college is 13.038 units
