Answer:

The parametric equations for the line.x(t)=

y(t)=

z(t)=

is  

 \= r (t) =  \left \{ {{x(t)= 4-3t} \atop {y(t)= -5+t}}  \atop {z(t)=3-t}} \right \}

Step-by-step explanation:

From the question we are told that

      the given equation is

                \= r(t) =  (4-3t) + (-5 + t) + (3-t)

This given equation can be represented as

             \= r (t) =  [4 -3t , -5+t,3-t]

Generally this equation can be represented in terms of the parametric equations as follows

   \= r (t) =  \left \{ {{x(t)= 4-3t} \atop {y(t)= -5+t}}  \atop {z(t)=3-t}} \right \}

This above equation is obtained by assigning each component of r(t) to each  line

<h3>Answer: Choice A. Graph (1)</h3>

Reasoning:

If it is at all possible to draw a single vertical line through more than one point on the curve, then the graph is not a function. With graphs (2), (3) and (4), we can draw a vertical line through more than one point on those curves, so they aren't functions. Graph (1) is the only thing left. This graph is a function because it is not possible to draw a single vertical line through more than one point. It passes the vertical line test. Any input (x) leads to exactly one and only one y output.

Nice work on getting the correct answer when you chose "graph (1)".

Answer: 18.7

Step-by-step explanation:

Find the lengths of AB, BC, and CA

AB = \sqrt{(4-(-1))^{2} + (-1-4)^{2} } = 5\sqrt{2} ≈ 7.1

BC = \sqrt{(0-(-1))^{2} + (-3-4)^{2} } = 5\sqrt{2} ≈ 7.1

CA = \sqrt{(0-4)^{2} + (-3-(-1))^{2} } = 2\sqrt{5} ≈ 4.5

7.1 + 7.1 + 4.5 = 18.7

During a fundraiser, Ms. Dawson’s class raised $560, which is 25% more than Mr. Casey’s class raised. How much money did Mr. Cas
evablogger [386]

Answer:

$420

Step-by-step explanation:

To work this out you would need to find the 25% decrease of 560. To do this you would first divide 25 by 100, which gives you 0.25. Then you would minus 0.25 from 1, which gives you 0.75. This is because when finding percentage decreases you would first have to convert it into a decimal. Then you would have to minus it from 1 , to make sure that it will be a 25% decrease not a 75% decrease. Then you would multiply 560 by 0.75, which gives you 420.

1) Divide 25 by 100.

25/100=0.25

2) Minus 0.25 from 1.

1-0.25=0.75

3) Multiply 560 by 0.75.

560*0.75=$420

How do you write 2,252/ 1,000 as a percentage?
REY [17]
225% 2252/1000 is a fraction so you divide and get 2.25 and move the decimal point over two to the right.
