Answer:

x-6y=-9

Correct answer: Option b

Step-by-step explanation:

<u>Equation Of A Line </u>

The standard equation of a line is given by

y=mx+b

Where m is the slope of the line and can be computed as

\displaystyle m=\frac{d-b}{c-a}

Where (a,b), (c,d) are two known points of the line. Let's use the points (-3, 1), (3, 2)

\displaystyle m=\frac{2-1}{3+3}

\displaystyle m=\frac{1}{6}

The value of b can be obtained by using any point and the value of m. Let's use (3,2)

\displaystyle 2=\frac{1}{6}(3)+b

b=2-\frac{1}{2}=\frac{3}{2}

The equation of the line is

y=\frac{1}{6}x+\frac{3}{2}

Multiplying by 6

6y=x+9

Rearranging

x-6y=-9

Correct answer: Option b

Write the first five terms of the arithmetic sequence. a4 = 22, a10 = 64
dedylja [7]
Hello :
the general term is : 
an = a1+(n-1)×d  
or : an = ap +(n-p)×d......d is common diffrence
let : n=10 and p= 4
a10 =  a4 +(10-4)×d
64 = 22 + 6d
6d =  42
d= 7
conclusion :
a4 = 22
a3 = 22-7=15
a2=15-7=8
a1= 8-7=1
<span>the first five terms : 1 , 8 , 15 , 22</span>

A 9,000-lb load is suspended from the roof in a shopping mall with a 16-ft-long solid aluminum rod. The modulus of elasticity of
Westkost [7]

Answer:

Step-by-step explanation:

Given:

elongation, x = 0.50 in

Force, f = 9000 lb

Young modulus, E = 10,000,000 psi

Maximum Stress, Sm = 30000 psi

Length, L = 16 ft

Converting ft to in,

12 in = 1 ft

=16 × 12 = 192 in

Young modulus, E = stress/strain

Stress = force/area, A

Strain = elongation, x/Length, L

E = f × L/A × E

1 × 10^7 = stress/(0.5/16)

= 26041.7 psi

Minimum stress = 26041.7 psi

Maximum stress = 30,000 psi

Stress = force/area

Area = 9000/26041.7

= 0.3456 in^2

Stress = force/area

Area = 9000/30000

= 0.3 in^2

Using minimum area of 0.3 in^2,

A = (pi/4)(d^2)

0.3 in^2 = (pi/4)(d^2)

d = 0.618 inches

diameter, d = 0.618 inches
