Step-by-step explanation:
Given :
log(a) + log(b) + log(c) = log(a + b + c)
We know that by property
log(a) + log(b) + log(c) = log(abc)
Therefore,
log(abc) = log(a + b + c)
Thus,
(abc) = (a + b + c)
Thus when a = b = c = 0,
then (abc) = (a + b + c)
0 = 0
and when a = 1, b = 2, c = 3,
then (abc) = (a + b + c)
(1 x 2 x 3 ) = (1 + 2 + 3)
6 = 6
Answer:
50° & 90°
Step-by-step explanation:
it's a right angle triangles, so one must be 90°
Interior angles in a triangle add up to 180.
180 - 90 - 40 = 50°
<u>Answer:</u>
$7.78
<u>Step-by-step explanation:</u>
3.18 lb (grapes) x $0.99 = $3.15 (Real answer: 3.1482. Rounded to the nearest cent)
1.25 lb (peaches) x $1.09 = $1.36 (Real answer: 1.3625. Rounded to the nearest cent)
2.75 lb (pears) x $1.19 = $3.27 (Real answer: 3.2725. Rounded to the nearest cent)
$3.15 (grapes total) + $1.36 (peaches total) + $3.27 (pears total) = $7.78 (total bill)
<u>Final Answer:</u>
$7.78

Answer:
The required specific heat is 196.94 joule per kg per °C
Step-by-step explanation:
Given as :
The heat generated = Q = 85.87 J
Mass of substance (m)= 34.8 gram = 0.0348 kg
Change in temperature = T2 - T1 = 34.29°C - 21.76°C = 12.53°C
Let the specific heat = S
Now we know that
Heat = Mass × specific heat × change in temperature
Or, Q = msΔt
Or, 85.87 = (0.0348 kg ) × S × 12.53°C
Or , 85.87 = 0.4360 × S
Or, S = 
∴ S = 196.94 joule per kg per °C
Hence the required specific heat is 196.94 joule per kg per °C Answer
