Find what x equals<br> (3/8)+x=(5/8)<br><br> find what t equals<br> t-(-5)=10

Dmitry_Shevchenko [17]

Answer:

X= 1/4 or in decimal form 0.25

T = 5

Step-by-step explanation:

For (3/8)+x=(5/8) Just do 5/8-3/8 which equals 1/4.

For t-(-5)=10 I used a calculator.

Find the length of RS with endpoints R(4,5) and S(-1, – 4).

Artist 52 [7]

Answer:

$d=\sqrt{106}$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

$d=\sqrt{(-1-4)^2+(-4-5)^2}$

$d=\sqrt{(-5)^2+(-9)^2}$

$d=\sqrt{25+81}$

$d=\sqrt{106}$

What came first into your mind when you read the word “union"? How did you

vodomira [7]

Answer:

well when you hear "union" you think 'joined' or 'together' since thats what it means, In a mathmatical set of numbers, union means that both of the sets are necessary for the equation to be true. I'm not sure what the sets are in this problem but in order to get "union" from anything, that means that when you checked for your domains, the values that you got had to be part of both the given sets

A roller coaster starts with the cars being pulled up a ramp. The mass of the cars is estimated by the function m(p) = 175p + 1,

KiRa [710]

Answer:

$E(p)=51,450p+346,920$

Step-by-step explanation:

The function

$m(p) = 175p + 1,180$

gives the mass of the car as a function of the number of passengers in it.

And the function

$E(m) = 9.8m*h$

gives the potential energy of the car as a function of the car's mass.

Now if the height of the ramp is 30 meters, we have

$E(m) =9.8m*(30)$

$E(m) =294m$

And to find the potential energy as a function of the number of passengers, we just substitute $m(p)$ into $E(m)$ to get:

$E(m(p))=294(175p+1180)$

$\boxed{ E(p)=51,450p+346,920}$

which gives the potential energy as a function of the number of passengers.
