I need more info on the prism
Given,
A linear function consisting of 2 terms, one is dependent on time and the other one is independent of time, i.e.,
A = -2.3t - 7
The dependent term -2.3 indicates that the altitude of Mr Mole decreases by 2.3 meters every minute.
At t = 0, A = -2.3(0) - 7 = 0 - 7 = -7. (Negative sign indicates the value is below the ground level of 0 meter.
The constant term - 7 is the altitude at t = 0, because at t = 0
Thus, Mr. Mole's burrow lie 7 meters below the ground.
We must know how many inches the plant grows in one month.
13 ÷ 5 = 2.6
The plant grows 2.6 inches a month.
Simply multiply 2.6 by the corresponding months to fill in the rest of the boxes.
(2x+1)=Jeremy´s age
(2x+3)=Sam´s age.
we suggest this equation:
(2x+1)(2x+3)=783
4x²+6x+2x+3=783
4x²+8x-780=0
x²+2x-195=0
We solve this quadratic equation:
x=[-2⁺₋√(4-4*1*(-195))]/2=(-2⁺₋28)/2
x₁=(-2-28)/2=-15 this solution is not valid.
x₂=(-2+28)/2=13
Jeremy´s age=2x+1=2*13+1=27
Sam´s age=2x+3=2*13+3=29
answer:
538.89576473...
