A rectangular piece of tin has an area of 1056 square inches. A square of 3 inches is cut from each corner, and an open box is m

kvv77 [185]

Answer:

44 inches and 24 inches

Step-by-step explanation:

Let $l,b$ denotes length and breadth of a rectangle.

$lb=1056$

A square of 3 inches is cut from each corner, and an open box is made by turning up the ends and sides.

New length $=l-6$ inches

New breadth $=b-6$ inches

Height of box $=3$ inches

Volume of box = length × breadth × height

$(l-6)(b-6)3=2052$

$lb-6l-6b+36=684\\6(l+b)=408\\l+b=68\\b=68-l$

Put $b=68-l$ in $lb=1056$

$l(68-l)=1056\\l^2-68l+1056=0\\l^2-44l-24l+1056=0\\l(l-44)-24(l-44)=0\\(l-24)(l-44)=0\\l=24,44$

At $l=24,b=\frac{1056}{24}=44$ inches

At $l=44,b=\frac{1056}{44}=24$ inches

Graph this equation of a circle?<br>I'm stuck and I don't know how to approach this math problem.

Soloha48 [4]

First use the distance formula to find the radius of the circle:
d= $\sqrt{ ( x_{2}- x_{1}) ^{2}+ ( y_{2}- y_{1}) ^{2} }$

d= $\sqrt{ (-1-23)^{2}+ (5--2)^{2} }$

d= $\sqrt{ (-24)^{2}+ (7)^{2} }$

d= $\sqrt{ (-24+7)^{2} }$

d= $\sqrt{ (-17)^{2} }$

d=|17|
d=17

Next, find the equation of the circle (use the first picture):
(x+1)^2+(y-5)^2=17^2

Finally, input the equation into a graphing calculator:

guapka [62]

Answer:

I know this is late but hopefully this helps someone reading this in the future. the answer is y = 43(3)^x

Step-by-step explanation:

If kyle starts out with with 43, and the amount triples everyday, it would be 3 to the power of x (how many days there are), which would make that the equation. Sorry, if this explanation makes no sense.
