Answer:
✔️ 198.7 m²
✔️$219.9
Step-by-step explanation:
✔️Area around the wall to be painted = area of rectangle - area of triangle
= L×B - ½ab×sin(C)
Where,
L = 17 m
W = 14 m
a = 9.5 m
b = 8.7 m
C = 72°
Plug in the values
Area around the wall to be painted = 17×14 - ½×9.5×8.7×sin(72)
= 238 - 39.3024105
≈ 198.7 m² (nearest tenth)
✔️Cost of painting the wall:
Paint cost $21.99 per container of 20 liters
Find how many liters would be needed if 1 liter covers 1m²
Liters needed to cover 198.7 m² = 198.7*1 = 198.7 liters of paint
20 liters = 1 container,
198.7 liters = 198.7/20 = 9.935 ≈ 10 containers
1 container cost $21.99
10 containers = 21.99×10 = $219.9
Answer:

Step-by-step explanation:
Given: 
To find: value of x and y
Solution:

From equation (i) and (ii),

Put
in (i)

Use the slope formula and slope-intercept form
y=mx+b
to find the equation.
y=2/11x + 4/11
Hope this helps
Differentiate the given solution:

Substitute
and
into the ODE:

and it's easy to see the left side indeed reduces to 0.
Answer:
for the 1st one the answer is x= 3 y=1 and the second one is x= 5 and y = 3 and 1/3
Step-by-step explanation: so basically for the first one -5 times x which is 3 is -15 right? and then 5 times y which is 1 is 5 right so -15 plus 5 = -10
second one is x = 5 and y = 3 and 1/3 because 5*x which is 5 is = to 15 right? and then 3 times y which is equal to 3 and 1/3 is equal to 10 which when you do 15-10 in pretty sure it equals 5 correct me if im wrong
Hope this helps xD ;)
