Solve for x. √x−11=5

I'll give 100 brainly points, i just need help...plz

Answer:

A. $(x^{2/7})(y^{-3/5})$

Step-by-step explanation:

The numerator is:

$\sqrt[7]{x^2} = (x^2)^{1/7} = x^{2/7}\\$

The denominator is:

$\sqrt[5]{y^3} = (y^3)^{1/5} = y^{3/5}$

The fraction is equivalent to:

$\frac{x^{2/7}}{y^{3/5}} =$
$(x^{2/7})(y^{-3/5})$

Correct choice is A

Mister Rogers is fencing another new rectangular garden in his neighborhood. One side of the garden faces the road and needs to

Oksanka [162]

Answer:

length of the pretty side and length of the side oppositte to the pretty side = 37.91 ft

length of the other two sides = 27.52 ft

Step-by-step explanation:

The mathematical problem is:

Max A = b1*h

subject to: 35*b1 + 18*(2*h + b2) <= 3000

Where

A: area of the garden

b1: length of the pretty side

b2: length of the side oppositte to the pretty side

h: length of the other two sides

Replacing with b1 = b2 and taking only the equality sign in the restriction (in the maximum all the money will be spent), we get:

35*b1 + 18*(2*h + b1) = 3000

35*b1 + 36*h + 18*b1 = 3000

53*b1 + 36*h = 3000

b1 = 3000/53 - (36/53)*h

Substituing in Area's formula

A = (3000/53 - (36/53)*h)*h

A = (3000/53)*h - (36/53)*h^2

In the maximum, the derivative of A is equal to zero

dA/dh = 3000/53 - 2*(36/53)*h =

3000/53 - 72/35*h = 0

h = (3000/53)*(35/72)

h = 27.52 ft

then,

b1 = 3000/53 - (36/53)*27.52

b1 = 37.91 ft =b2

A book has n consecutive pages torn out. Suppose A is the last numbered page before the torn-out section and B is the first numb

Sergio039 [100]

The answer is n=(a-b)-1 because when you subtract a-b, you get almost the number of pages, but as you are counting the page b which has is not torn out, you must subtract 1 to get the correct answer if you plugged in a variable

Determine whether the statement is true or false.

forsale [732]

<h3>A circle $(x+4)^2+(y-2)^2=85$ passes through point (2, -5) is true</h3>

Solution:

Given equation of circle is:

$(x+4)^2+(y-2)^2=85$

Given statement is:

A circle $(x+4)^2+(y-2)^2=85$ passes through point (2, -5)

We have to say whether the statement is true or false

Substitute x = 2 and y = -5 in given equation

$(2+4)^2 + (-5-2)^2 = 85\\\\6^2 +(-7)^2 = 85\\\\36 + 49 = 85\\\\85 = 85$

The point (2 , -5) satisfies the given circle equation

Thus the statement is true
