Answer:

Step-by-step explanation:

Alright, lets get started.

There are 6 different stages of Tina's bike ride.

First: When she starts, her speed continuous increases means graph goes up.

Second : After seeing the stop sign, she slows down and speed reached to zero.

Third : She waits at stop sign, so, there is zero speed for some time.

Fourth : She again starts but at lower speed than previous speed.

Fifth : She makes a ride with steady speed.

Sixth : She finally slow down her speed and ends to zero.

So, the answer is second graph.

The owner of an office building is expanding the length and width of a parking lot by the same amount. The lot currently measure

Gnoma [55]

The best and most correct answer among the choices provided by your question is the second choice or letter B "20".

The current area is 120(80)=9600 and he want to expand it by 4400 so that the new area will be 9600+4400=14000

14000=(120+x)(80+x)

14000=9600+200x+x^2

x^2+200x-4400=0

x^2-20x+220x-4400=0

x(x-20)+220(x-20)=0

(x+220)(x-20)=0, since x is an increase it must be greater than zero so

x=20ft

(120+20)(80+20)=14000ft^2

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

How to solve this problem

rodikova [14]

$\bf \textit{circumference of a circle}\\\\
C=2\pi r\quad 
\begin{cases}
r=radius\\
-----\\
r=10
\end{cases}\implies C=2\pi 10\implies \boxed{C=20\pi }\\\\
-------------------------------\\\\$

$\bf \textit{let's converte 1km to inches}
\\\\\\
km\cdot \cfrac{1000m}{km}\cdot \cfrac{100cm}{m}\cdot \cfrac{in}{2.54cm}\implies \cfrac{1000\cdot 100\cdot in}{2.54}\approx 39370.079\ in\\\\
-------------------------------\\\\
\textit{how many times does }20\pi \textit{ go into }39370.079?\implies \boxed{\cfrac{39370.079}{20\pi }}$

A home’s value increases at an average rate of 5.5% each year. The current value is $120,000. What function can be used to find

notsponge [240]

So we need to cover 5.5% into a decimal.

0.055 = 5.5%

The house value is 120,000.
So

(1.055x) * (120,000)=

So

f(x)=1.055x * 120,000
