Answer:
U did not add a picture but if u do I will help.
Step-by-step explanation:
It should be 8 to the right and 12 to the left which should end at -4
Answer:
C
Step-by-step explanation:
Cause C met the rules of scientific notation which is:
- (First digit of the number) followed by (the decimal point) and then (all the rest of digits of the number) times (10 to an appropriate power)
Answer:
69.92°F
Step-by-step explanation:
Given:
Initial temperature ( i.e at time, t = 0) = 40°F
Temperature of the room = 70°F
Temperature after 10 minutes ( i.e at time t = 10 ) = 48°F
Now, from Newton's law of cooling
T'(t) = k(A - T(t))
T(t) temperature after time t
T'(t) =
here, A is the room temperature
thus,
= k(70 - T)
or
= kdt
on solving the differential equation, we get
T =
............(1)
Now from the boundary conditions,
i.e at time, t = 0; T = 40°F
we get,
40 = 
or
C = 30
and,
at time, t = 10; T = 48°F
thus,
48 = 
or
k =
or
k = 0.03
Therefore,
for t = 25
from 1 we have
T = 
or
T = 70 - 0.0780
or
T = 69.92°F
Answer:
First find the area of the square
(s x s)
10x10
=100
And then for the triangles
(1/2bh)
1/2 x 10 x 12
=60
since there are 4 triangles of the same area we will multiply 4 with the first triangle's area
60 x 4
=240
Total S.A= 240 + 100
=340 Square Inches
Option B
Hope it helps!
