Help for 15 points . ill up it

RoseWind [281]

Step-by-step explanation:

Let $P_1(-1, -8)\:\text{and}\:P_2(-4, -9)$

The slope of the line through these two points is

$m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{(-9 + 8)}{(-4 + 1)} = \dfrac{1}{3}$

So the slope-intercept form of the line passing through the two points is

$y = mx + b = \frac{1}{3}x + b$

To find b, we use either point into our equation. Let's use (-1, -8):

$-8 = \frac{1}{3}(-1) + b \Rightarrow b = -\dfrac{23}{3}$

Therefore, the slope-intercept form of the equation for the line is

$y = \dfrac{1}{3}x - \dfrac{23}{3}$

The standard form of the equation can be written as

$x + 3y + 23 = 0$

Consider a steel guitar string of initial length L=1.00 meter and cross-sectional area A=0.500 square millimeters. The Young's m

Goshia [24]

Answer:

15mm

Step-by-step explanation:

we are looking for extension

To get Extension you need the original length and the strain both of which you are given

initial length L = 1.00m

the area A = 0.5mm² = 0.5 mm² = 0.5 x 10⁻⁶ m² ( we are changing to metres squared)

E = 2.0 x 10¹¹ n/m², Young's modulus

P = 1500N, the applied tension

Now to Calculate the stress.

σ = P/A (force/area) = (1500 N)/(0.5 x 10⁻⁶ m²) = 3 x 10⁹ N/m²

Also, Let β = the stretch of the string.

Then the strain is

ε = β/L (extension/ original length)

By definition, the strain is ε = σ/E = (3 x 10⁹ N/m²)/(2 x 10¹¹ N/m²) = 0.015

Therefore β/(1 m) = 0.015β = 0.015 m = 15 mm

Answer: 15 mm

HI CAN I GET SOMEONE TO HELP ME WITH MATH IM FAILING TY! :)

oksano4ka [1.4K]

Answer:

20 square meters

Step-by-step explanation:

area = length x width

area of grass = 4 x 4 = 16

area of grass and cement = 6 x 6 = 36

<em>Now you subtract to find the area of the cement.</em>

36 - 16 = 20
