Answer:
I am deeply sorry for the late answer
but the answer is The answer is
r ≈ 6
Step-by-step explanation:
The answer is r ≈ 6
A ≈ 113.04 cubic in.
this means that
d ≈ 12
and
C ≈ 37.69
Therefore
r ≈ 6
Hope this helped.
If a line is parallel to another line,Then the gradients are the same.So m=4 .Using general formula for str8 line, y=mx+c

sub in coorfinates (1,13)

So C=9.
Answer:
3. 17x + 5 = 90° ( alternate exterior angles are equal)
=> 17x + = 90 – 5
=> 17x = 85
=> x = 85/17
=> x = 5
4. 63° + c + 110° + 75° + 50° = 360 °
=> c + 298° = 360°
=> c = 360° – 298°
=> c = 62 °
Answer:
Properties of Real Numbers ...
Step-by-step explanation:
Commutative Property of Multiplication (Numbers) 2 • 10 = 10 • 2
Associative Property of Addition (Numbers) 5 + (6 + 7) = (5 + 6) + 7
Associative Property of Multiplication (Numbers) 6 • (3 • 2) = (6 • 3) • 2
Additive Identity (Numbers) 6 + 0 = 6
Newton's law of cooling is
k (t₁ - t₂) = -ln (T₁ - T∞ / T₂ - T<span>∞)
Use the two data points in the given to find k.
t = 0, T = 154
t = 10, T = 133
Solution:
k(0 - 10) = - ln (154 - 71/ 133 - 71)
-10k = -0.291716
k = 0.02917 or 0.0292
So now find t when T = 100
0.2917 * ( 0 - t) = -ln (154 - 71 / 100 -71)
- 0.02917t = - 1.0515
t = 36. 05 minutes
to the nearest minute t = 36</span>
