A rectangular yard has a width that is 10 feet longer than the width . If the the area of the yard is 600 squared feet , find th
olga55 [171]

Answer:

length = 30 feet and width = 20 feet

Step-by-step explanation:

Let l is length and b is width of a rectangular yard. The area of a rectangle is given by :

A = lb ..(1)

A rectangular yard has a length that is 10 feet longer than the width.

length, l = 10+b ...(2)

ATQ,

Put the value of l in equation (1),

(10+b)b=600\\\\10b+b^2=600\\\\b^2+10b-600=0\\\\b^2+30b-20b-600=0\\\\b(b+30)-20(b+30)=0\\\\(b+30)(b-20)=0\\\\b=-30\ \text{feet}\ \text{and}\ b=20\ \text{feet}

Width can't be negative. The width is 20 feet.

Put the value of b is equation (2),

l = 10+20

l = 30 feet

Hence, the length and width are 30 feet and 20 feet.

Bet u can’t solve this
S_A_V [24]

Answer:

Step-by-step explanation:

Assuming you're solving for p:

m=2^{-1} *2^p(2^p-1)

Let y=2^p

Now we can re-write the equation with y instead of 2^p.

m=\frac{1}{2} y(y-1)

2m=y^2-y

y^2-y-2m=0

Use the quadratic formula to get:

y = \frac{1+\sqrt{1+8m} }{2}

or

y = \frac{1-\sqrt{1+8m} }{2}

Therefore, using natural log and log rules:

2^p = \frac{1+\sqrt{1+8m} }{2}, ln(2^p)= ln(\frac{1+\sqrt{1+8m} }{2}),pln(2) = ln(\frac{1+\sqrt{1+8m} }{2}), p = \frac{ln(\frac{1+\sqrt{1+8m} }{2})}{ln(2)}

or

2^p = \frac{1-\sqrt{1+8m} }{2}, ln(2^p)= ln(\frac{1-\sqrt{1+8m} }{2}), pln(2) = ln(\frac{1-\sqrt{1+8m} }{2}), p = \frac{ln(\frac{1-\sqrt{1+8m} }{2})}{ln(2)}

If I haven't made any mistakes this should be correct!
