Hello,

1)
y=(2x-7)(x+5)^3

y'=2(x+5)^3+(2x-7)*3*(x+5)²
if x=4 then
y'=2*9^3+1*3*9²=1701

2)
y=(3x-2)/√(x+2)

y'=(3*√x+2 - (3x-2)/(2*√x+2))/(x+2)

Find the slope of the line passing through the points (8,-4) and (-7, -4).
Tju [1.3M]

Answer:

Step-by-step explanation:

slope=m=(Y2-Y1)/(X2-X1)

As given values

take,   (X1,Y1)=(-7,-4)

          (X2-Y2)=(8,8)

hence   X1=-7  ,  Y1= -4   ,  X2=8  , Y2= 8

putt the values in the above equation of slope we get ,

m=(8-(-4))/(8-(-7)

m=12/15    Ans

Jai Narayan sells two radio sets for 2288 each.
san4es73 [151]

Answer:

1%

Step-by-step explanation:

S.P of each radio=$ 2288

Total S.P=2\times 2288=$4576

Gain=10%

Lose=10%

C.P=\frac{S.P\times 100}{100+gain(in\;percent)}

C.P=\frac{S.P\times 100}{100-loss(in\;percent)}

By using the formula

C.P of one radio=\frac{2288\times 100}{110}=$2080

C.P of another radio=\frac{2288\times 100}{100-10}=$2542.2

Total C.P of two radios=2080+2542.2=$4622.2

Total C.P >Total S.P

Loss=S.P-C.P

Loss=4622.2-4576=$46.2

Loss%=\frac{Loss}{C.P}\times 100

Loss %=\frac{46.2}{4622.2}\times 100=1%

Hence, his loss 1%
