Answer:
216 cubic meters
Step-by-step explanation:
to find the volume of any prism the equation is bh or base times height
the base is a triangle so you find the triangles area and multiply it by the height
8 * 6 * 1/2 = 24
24 * 9 = 216
216 cubic meters
Substitute y=4x to the second equation:
x^2 + (4x)^2 = 17
x^2 + 16x^2 = 17
17x^2 = 17
x^2 = 17/17
x^2 = 1
x = 1 and -1
When x=1, y=4(1) = 4
When x=-1, y=4(-1) = -4
Thus the solutions would be (1,4) and (-1,-4). That would correspond to D. and A.
Step-by-step explanation:
Distance = rate × time
If b is the speed of the boat in still water, and c is the speed of the current, then:
60 = (b + c) × 4
35 = (b − c) × 3.5
Simplifying:
15 = b + c
10 = b − c
Add the equations together:
25 = 2b
b = 12.5
Plug into either equation to find c:
c = 2.5
The speed of the boat is 12.5 km/h, and the speed of the current is 2.5 km/h.
What you do is turn them in to improper fractions
you will have 15/4 times 12/5 then multiply
you would get 180/20 and you simplify it to get
9/1 witch = 9
Answer:
f(x)=x+1/11
Step-by-step explanation:
These two lines would be perpendicular.
