Suppose y varies directly as x , and y=−319 when x = 29. Based on this information, write a direct variation equation that relat

Len [333]

Answer:

$y = - 11x$

Step-by-step explanation:

If y varies directly as x, then we can write the relation

$y = kx$

where k is the constant of proportionality.

We substitute y=-319 when x=29.

$- 319 = 29k$

This implies that:

$k = \frac{ - 319}{29}$

$k = - 11$

The variation equation now becomes

$y = - 11x$

Is 0.07 less than 0.06

Kobotan [32]

No, .007 is not less than .006. Not only is the decimal form evidence of these integers, but writing them as a percentage can also decipher the question.

Since .007 equals to 7% (0.07 = 7/100) and 0.06 equals to 6% (0.06 = 6/100) then 7% is greater than 6%, therefore, answering you question.

Use the distance formula to find the perimeter of the triangle below. Round you answer to the nearest hundredth.

Murrr4er [49]

jAlright, let's take this problem step-by-step:

What is the perimeter:

⇒ all the side-lengths added up

⇒ need to find side-length using distance formula

$Distance_._. Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

- (x₁,y₁): first point

- (x₂,y₂): second point

Let's solve:

Find length of AC

⇒ first point: (5,7)

⇒ second point: (3,3)

$Distance =\sqrt{(3-5)^2+(3-7)^2} =\sqrt{4+16} =\sqrt{20} =4.472$

Find length of AB

⇒ first point: (5,7)

⇒ second point:(8,6)

$Distance=\sqrt{(8-5)^2+(6-7)^2} =\sqrt{9+1} =\sqrt{10}=3.162$

Find length of BC

⇒ first point: (8,6)

⇒ second point: (3,3)

$Distance = \sqrt{(3-8)^2+(3-6)^2} =\sqrt{25+9} =\sqrt{34}=5.831$

Now let's solve for the perimeter:

$Perimeter = 4.472+ 3.126+ 5.831=13.429$

Answer: 13.43 (rounded to the nearest hundredth)

Hope that helps!
