Answer:
I think the oil pollutes the groundwater
Step-by-step explanation:
My six grade science teacher once taught us something about this, but that was a year ago so I might be wrong, but I'm pretty sure that the oil will spread and then pollute local rivers and streams, by polluting the groundwater.
R = 6t.....subbing in (8,48).....t = 8 and r = 48
48 = 6(8)
48 = 48 (correct)
r = 6t...subbing in (13,78)...t = 13 and r = 78
78 = 6(13)
78 = 78 (correct)
so u have 2 sets of points on this line and they are (8,48) and (13,78)
Answer:
Width = 5
Length = 2*5 = 10
Step-by-step explanation:
Givens
Let the width = W = x
Let the length = L = 2x
Equation
Area = L * W
Solution
Area = 2W * W Substitute into the given equation
Area = 2W^2 Simplify the right
50 = 2W^2 Divide by 2
50/2 = 2W^2 / 2 Simplify
25 = W^2 Switch
W^2 = 25 Take the square root of both sides
sqrt(w^2) = sqrt(25)
Answers
w = 5 ft
L = 2 * 5 = 10 ft
Answer:
73 degrees
Step-by-step explanation:
Given that the temperature during a day can be modeled by a sinusoid.
At 4 am. lowest = 53 deg and at 4 pm highest = 99 deg
Amplitude = (99-53)/2 = 23
Mean temp = 76 deg
If 4 am is taken as t =0 then we have middle temp = 46 degrees at 10 a.m.
Hence equation would be of the form
T(t) =23 sin (pi t/12)+53 where T is the temperature and t is time in hours from 4 a.m.
At 8 am t =4
So T(4) = 23 sin pi/3 +53 = 19.92+53 =72.92
Nearly 73 degrees
Answer:
The time the ball will hit the ground is 1.4s
Step-by-step explanation:
Given;
function of the ball's motion; h(t)= -5t²+ 14t + 3h
The final velocity of the ball, v , is given as;
v = dh/dt
v = -10t + 14
When the ball hits the ground, the final velocity, v = 0
v = -10t + 14
0 = -10t + 14
10t = 14
t = 14 / 10
t = 1.4s
Therefore, the time the ball will hit the ground is 1.4s
