What is the area of the region bounded by the lines x= 1 and y= 0 and the curve y=xe^x^2?
Mice21 [21]

Answer:

A = 0.859

Step-by-step explanation:

We want to find the area of the region bounded by the lines x = 1 and y = 0 and the curve y = xe^(x²).

At y = 0, let's find x;

0 = xe^(x²)

Solving this leads to no solution because x is infinity. Thus we can say lower bound is x = 0.

So our upper band is x = 1

Thus,lets find the area;

A = ∫xe(x²) dx between 1 and 0

A = (e^(x²))/2 between 1 and 0

A = ((e¹)/2) - (e^(0))/2)

A = 1.359 - 0.5

A = 0.859

Please show steps on how to solve <br> log7 -2b-9=-6
NeTakaya

Answer: b= - -log10(7)+3/2

Step-by-step explanation: log 10 (7) -2b-9=-6 : b= - -log10(7)+3/2 (Decimal : b = -1.07745...)

so these are the steps how I got it I did log 10 (7)-2b-9=-6 subtract log 10 (7) -9 from both sides log 10 (7)-2b-9-(log10(7)-9)=-6-(log 10 (7) -9)

Simplify -2b= -log10(7)+3

Divide both sides by -2  -2b/2= - log 10(7)/-2+ 3/-2 if you simplify it should give you b= - -log10(7)+3/2 that should be your answer but i'm not sure those I think that's how you do it let me know if you got it right bye!

Ivan had a total of 9 pigs and chickens on his farm. There was a total of 30 legs. How many of each did he have ?
luda_lava [24]

Answer: 6 pigs and 3 chickens

Step-by-step explanation: you know that each pig has 4 legs and each chicken has 2 legs so start out by saying 9 pigs and 0 chickens which is 36 legs then try 8 pigs and 1 chickens and 8 times 4 = 32 + 2 which is 32 which is more than 30 then notice for every chicken there is you subtract 2 from 36

knowing this we can divide 6 by 2 and get 3 the number of chickens

so 6 pigs and 3 chickens      

hope this helps mark me brainliest if it helped
