Alexeev081 [22]

Solving this problem is just pretty straight forward. We simply have to get the ratio of distance and time to get the speed. that is:

speed = distance / time

speed = 100 m / 10.94 s

speed = 9.14 m/s

2 (4x - 8) + 16t = 48

Effectus [21]

Distributive property first so you wanna do 2•4 then you will get 8x then you have to do 2•8 Wich is 16 then you will end up with 8x-16+16t=48 move the expression to the right 8x=48+16-16t 8x=64-16t x=8-2t?

Remember that the general decay equation is:
$y=A(1-r)^{x}$
where
$y$ is the amount after a time $x$
$A$ is the initial amount
$r$ is the the decay percent in decimal form

The first ting we are going to do is find $r$ by dividing our decay rate of 25% by 100%: $r= \frac{25}{100} =0.25$ .
We also know from our problem that $y=64$ . Lets replace $y$ and $r$ in our formula:
$64=A(1-0.25)^{x}$
$64=A(0.75)^{x}$
We know now that our decay rate is 0.75, and since 0.75<1, we can conclude that this situation represents exponential decay.

Now, to find the initial amount, we are going to solve our equation for $A$ :
$64=A(0.75)^{x}$
$A= \frac{64}{0.75 ^{x} }$
Notice that $A$ will depend on the number of ours $x$ .

9(x) = 2x-1 r(x) = -2x 2 2 Find the value of r(q (2)).

BabaBlast [244]

Answer:

Answer is -6

Step-by-step explanation:

$given \: q(x) = 2x - 1 \\ and \: r(x) = - 2x \\ r(q(2)) = r(2(2) - 1) \\ \: \: = r(4 - 1) \\ = r(3) \\ = - 2(3) \\ = - 6 \\ therefore \: r(q(2)) = - 6$

HAVE A NICE DAY!
