The first and third graphs are both negative, so we can rule them out. Also, the fourth graph has no correlation, so we can rule that out. That leaves us with the final and correct answer, graph B.

Hope this helps!

A rectangle has a perimeter of 76 cm and length 31 cm what is its width

Snowcat [4.5K]

The formula for the perimeter of a rectangle is P = 2L + 2W

you are given P (perimeter) and l (length.

Replace the letters withe the given information and solve for width:

76 = 2(31) +2W

Simplify:

76 = 62 + 2w

Subtract 62 from both sides:

14 = 2w

Divide both sides by 2:

W = 14/2

W = 7 cm

The width is 7 cm.

I am having a hard time figuring this out can some one please help!1

aniked [119]

Answer:

$y=500\cdot 0.658^{\frac{x}{2}}$

Step-by-step explanation:

Express the weight as the exponential function of months

$y=a\cdot b^{\frac{x}{2}}$

When $x=0,$ then

$500=a\cdot b^{\frac{0}{2}}\\ \\500=a\cdot b^0\\ \\500=a$

Hence,

$y=500\cdot b^{\frac{x}{2}}$

When $x=2,$ then

$329=500\cdot b^{\frac{2}{2}}\\ \\329=500b^1\\ \\329=500b\\ \\b=\dfrac{329}{500}=0.658$

Therefore,

$y=500\cdot 0.658^{\frac{x}{2}}$

Check the rest values:

$x=4: \ y=500\cdot 0.658^{\frac{4}{2}}=500\cdot 0.658^2\approx 216\\ \\x=6:\ y=500\cdot 0.658^{\frac{6}{2}}=500\cdot 0.658^3\approx 142\\ \\x=8:\ y=500\cdot 0.658^{\frac{8}{2}}=500\cdot 0.658^4\approx 93\\ \\x=10:\ y=500\cdot 0.658^{\frac{10}{2}}=500\cdot 0.658^5\approx 61\\ \\x=12:\ y=500\cdot 0.658^{\frac{12}{2}}=500\cdot 0.658^6\approx 40$
