How many units of heat are needed to raise the temperature of 20.0 g of aluminum from 22°C to 55°C, if the specific heat of aluminum is 0.90 units?

(x, y)→(x − 8, y − 7)

step-by-step explanation:

enjoy!

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

answer: 0.26

i used the calculator on google

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
