Answer:
Step-by-step explanation:
Find the slope using the points, (1, -3) and (3, 1):
m = 2
Find the y-intercept (b) by substituting x = 1, y = -3, and m = 2 in 
Subtract 2 from both sides
Plug in the value of m and b into the slope-intercept form equation, .
Thus:
✅
Answer:the last one I’m not really sure
This is the derivative of S with respect to r, evaluated at r=8.
dS/dr = 8πr
Substituting r=8 into the above gives the answer of 64π.
DT/dt=k(T-38)
ln(T-38) = kt+C
T=38 + Ce^(-kt)
Since T(0)=75, 75 = 38+C, so C=37
Since T(30)=60, 60 = 38+37e^(-30k), so k = -ln(22/37)/30 ~= -0.017329
T(60) = 38+37e^(-0.017329*60) = 51.1°F
Answer:
Hope this answers the question.
Step-by-step explanation:
Factoring a number: If you use the number 10, for example, you have to find all the factors to factor it. 1, 2, 5, 10.
Factoring a trinomial: If you use the trinomial x^2 + 16 + 64, for example, to factor it you need to first find what numbers multiply up to 64 and also add up to 16. In this case, those numbers are 8, and so you get (x + 8)^2.
