4/5-3/7. First they need the same denominater: 4/5(7)=28/35, 3/7(5)=15/35. 28/35-15/35. Now subtract numerators: 28-15=13. So your answer H. 13/35 :)
Domain is the numbers yo can use
we has a sqrt and a ln
we cant have any neagtive ln's or sqrts
x cannot be negative
it cannot be 0 either
domain is all numbers bigger than 0
deritivive
apply chain rule
dy/dx(f(g(x))=f'(g(x))g'(x)
and also
dy/dx (lnx)=1/x
and
dy/dx(f(x)g(x))=f'(x)g(x)+g'(x)f(x)
and from experience
dy/dx(sqrtx)=1/(2√x)
so
dy/dx(ln(2xsqrt(2+x)))=
(1/(2xsqrt(2+x))(2)(sqrt(2+x)+(x/(2sqrt(2+x))=
(3x+4)/(2x(x+2))
domain is all real numbers greater than 0

Answer:
-10.76
Step-by-step explanation:
Let's solve your equation step-by-step.
4=314(1.5x)
Step 1: Flip the equation.
314(1.5x)=4
Step 2: Divide both sides by 314.
314(1.5x)/314
=
4/314
1.5x=2/157
Step 3: Solve Exponent.
1.5x=2/157
log(1.5x)=log(2/157)(Take log of both sides)
x*(log(1.5))=log(2/157)
x=
log(2/157)
log(1.5)
x=−10.760725
Answer:
x=−10.760725
Let Mike be m and Adam be m+2. Then:
m²+28=(m+2)²
m²+28=m²+4m+4
4m=24
m=6
Mike is 6; Adam is 8
☺☺☺☺
3^2+x^2=8^2
9+x^2=64
x^2 = 64-9=55
The answer is B
