Calculate the resistance of a 270-cm length of copper wire with a 0.030-cm2 cross-sectional area. ( = 1.8 · 10-6 ohm-cm) R = ___
devlian [24]

Answer:

Given:-

The length of copper wire (L) = 270 cm

Area of cross-sectional (A) = 0.030 cm^2

and specific resistance (ρ) = 1.8 \times 10^{-6} ohm-cm.

Use the formula  R=(Specific resistance*L)/A, to calculate the Resistance(R)

then, R=\frac{1.8 \times 10^{-6} \times 270}{0.030} ohm

Simplify:

R = 0.0162 ohm = 1.62\times 10^{-2} ohm

Therefore, the resistance of copper wire is,  1.62\times 10^{-2} Ω

4x-5y=-15 <br> 7x-2y=21 <br> X=<br> Y=
Helen [10]

Answer:

The values of x and y to the given equations are x=5 and y=7

Step-by-step explanation:

Given equations are 4x-5y=-15\hfill (1)

7x-2y=21\hfill (2)

To solve the given equations by elimination method :

Multiply the equation (1) into 2 we get

8x-10y=-30\hfill (3)

Multiply the equation (2) into 5 we get

35x-10y=105\hfill (4)

Now subtracting the equations (3) and (4) we get

8x-10y=-30

35x-10y=105

_________________

-27x=-135

x=\frac{135}{27}

Therefore x=5

Now substitute the value of x=5 in equation (1) we get

4(5)-5y=-15

20-5y=-15

-5y=-15-20

-5y=-35

y=\frac{35}{5}

Therefore y=7

The values are x=5 and y=7

Write an equation in standard form for a line that passes through (2,2) and (0, -3).
Alecsey [184]
First find the slope:
(-3-2)/(0-2)=-5/-2=5/2

So then y=5/2x+b

When x=0, then the y-coordinate with that is the y-intercept.

So the answer is y=5/2x-3.

What is the completely factored form of f(x) = 6x3 – 13x2 – 4x 15? (x 1)(6x2 – 19x 15) (x 1)2(2x – 3) (x 1)(3x – 2)(5x – 3) (x 1
ludmilkaskok [199]

The completely factored form of f(x) = 6x³ - 13x² - 4x + 15 is f(x) = (x + 1)(2x - 3)(3x - 5)

<h3>How to factor the expression?</h3>

The expression is given as:

f(x) = 6x³ - 13x² - 4x + 15

Expand the expression

f(x) = 6x³ - 19x² + 6x² + 15x - 19x + 15

Rewrite as:

f(x) = 6x³ + 6x² + 15x- 19x²   - 19x + 15

Factorize the equation

f(x) = (x + 1)(6x²- 19x + 15)

Expand (6x² - 19x + 15)

f(x) = (x + 1)(6x² - 10x - 9x + 15)

Factorize the expression

f(x) = (x + 1)(2x - 3)(3x - 5)

Hence, the completely factored form of f(x) = 6x³ - 13x² - 4x + 15 is f(x) = (x + 1)(2x - 3)(3x - 5)
