Kapil is programming a robot to always know its distance from its charging base by following these steps:
Step 1) save b, which is the current distance from the base
Step 2) Face charging base and turn 0° to the right
Step 3) Move x
Step 4) Compute new distance from the base
Step 5) Go back to Step 1
For example, it might happen that when the robot gets to step 4 in its program
b=70 units
Θ = 60°, and
x=50 units
In the example above, what would the robot's new distance from its base be?

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.

that would be a prism, if not right, feel free to correct me
