Determine whether lines are parallel, perpendicular or neither.

Mathematics
1 answer:
Phantasy [73]3 years ago
6 0

Answer:

Parallel.

Step-by-step explanation:

We need to  convert the 2 equations to  slope-intercept form (in bold) :-

2x + y = 8

y = -2x + 8.

6x + 3y = 12

3y = -6x + 12

Divide through by 3:

y = -2x + 4.

The slopes are the same (both  -2), so they are parallel.

What is the perimeter of △ABC?<br> Round each step to the nearest tenth.
trapecia [35]
Required Perimeter = AB + BC + CA
AB = sqrt((5 - (-1))^2 + (-1 - 1)^2) = sqrt(6^2 + (-2)^2) = sqrt(36 + 4) = sqrt(40) = 6.3
BC = sqrt((-1 - 0)^2 + (1 - (-3))^2) = sqrt((-1)^2 + 4^2) = sqrt(1 + 16) = sqrt(17) = 4.1
CA = sqrt((0 - 5)^2 + (-3 - (-1))^2) = sqrt((-5)^2 + (-2)^2) = sqrt(25 + 4) = sqrt(29) = 5.4

Perimeter = 6.3 + 4.1 + 5.4 = 15.8 units

An evergreen nursery usually sells a certain shrub after 9 years of growth and shaping. The growth rate during those 9 years is
Volgvan

Answer:

(a) After t years, the height is

18t² + 3t + 10

(b) The shrubs are847 cm tall when they are sold.

Step-by-step explanation:

Given growth rate

dh/dt = 1.8t + 3

dh = (18t + 3)dt

Integrating this, we have

h = 18t² + 3t + C

When t = 0, h = 10cm

Then

10 = C

So

(a) h = 18t² + 3t + 10

(b) Because they are sold after every 9 years, then at t = 9

h = 18(9)² + 3(9) + 10

= 810 + 27 + 10

= 847 cm
