The required coordinates of point B will be (2/9, -14/9).

Point A is at ( -3,4) and Point C is at ( 2,-6 )

Given that point B on line, AC suck as the ratio of AB to AC is 4:5

The coordinates of point B will be,

{[(mx2+nx1)/(m+n)],[(my2+ny1)/(m+n)]}

Breaking it down, the x coordinate is (mx2+nx1)/(m+n) and the y coordinate is (my2+ny1)/(m+n)

As per the question, m = 4 and n = 5

The coordinates of point B :

⇒ {[(4×-3+5×2)/(4+5)],[(4×4+5×-6)/(4+5)]}

⇒ {[(-12+10)/(9)],[(16-30)/(9)]}

⇒ (2/9, -14/9)

Thus, the required coordinates of point B will be (2/9, -14/9).

nikitadnepr [17]

Answer: y = 1/2x + 3

Step-by-step explanation:

Use the equation y=mx +b

Find the slope (m) of the line by finding the difference in y over the difference in x. Or "rise over run".

The y-intercept (b) is 3 (when x is zero, it is y).

Hello, a Maths question if anyone knows what to do Solve: 6(x+4)=30
eduard

Answer:

x = 1

Step-by-step explanation:

6(x+4)=30    (divide both sides by 6)

(x+4) = 30/6

x+4 = 5   (subtract 4 from both sides)

x = 5 - 4

x = 1

Wayne's service center operates a welding shop. Assume that the arrival of jobs follows a Poisson distribution with 2 jobs arriv
Reika [66]

Answer:

a) 0.3125 per hour

b) 2.225 hours

c) 8.9 hours

d) 12.1 hours

e) 80%

Step-by-step explanation:

Given that:

mean time = 3.2 hours, standard deviation (σ) = 2 hours

The  mean service rate in jobs per hour (λ) = 2 jobs/ 8 hour = 0.25 job/hour

a) The average number of jobs waiting for service (μ)= 1/ mean time = 1/ 3.2 = 0.3125 per hour

b) The average time a job waits before the welder can begin working on it (L) is given by:

L=\frac{\lambda^2\sigma^2+(\lambda/\mu)^2}{2(1-\lambda/\mu))} =\frac{0.25^2*0.2^2+(0.25/0.3125)^2}{2(1-0.25/0.3125)}=2.225\ hours

c) The average number of hours between when a job is received and when it is completed (Wq) is given as:

W_q=\frac{L}{\lambda}=2.225/0.25=8.9\ hours

d) The average number of hours between when a job is received and when it is completed (W) is given as:

W=W_q+\frac{1}{\mu} =8.9+\frac{1}{0.3125}=12.1 \ hours

e) Percentage of the time is Gubser's welder busy (P) is given as:

P=\frac{\lambda}{\mu}=0.25/0.3125=0.8=80\%

The product of two consecutive integers is 56.find the the integers.
defon

Let, the integers = x,(x+1)

x*(x+1) = 56

x²+x = 56

x²+x-56 = 0

x²+8x-7x-56=0

x(x+8)-7(x+8)=0

x+8= 0  OR x-7=0

x = -8 OR x = 7

it would be -8 & -7 or 7 & 8
