In 2015, an autonomous vehicle drove from the Golden Gate Bridge to New York City at an average speed of 15.7 miles per hour. Th
ivolga24 [154]

The speed is the distance covered by an object at a particular time. The distance that is covered by the vehicle is 3,391 miles.

<h3>What is speed?</h3>

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

Speed = Distance / Time

Given that the journey took 9 days. Therefore, the time in hours will be equal to,

Time = 24 hours/day × Number of days

        = 24× 9

        = 216 hours

Also, given that the speed of the vehicle is 15.7 miles per hour, the number of hours for which it travels is 216 hours.

Distance = Speed × Time

              = 15.7 miles/hour × 216 hours

              = 3,391.2 miles

Hence, the distance that is covered by the vehicle is 3,391 miles.

I Have 10 Minutes Hurry for Brainlist and pls be accurate

To find the equation we will put the values of x and y in the equations and then check if LHS=RHS.

\large\red{\sf{y=3x-1}}

  • x=1
  • y=9

\begin{gathered}\\ \sf\longmapsto 9=3(1)-1\end{gathered}

\begin{gathered}\\ \sf\longmapsto 9=3-1\end{gathered}

\begin{gathered}\\ \sf\longmapsto 9≠2 \end{gathered}

\large\green{\sf{y=5x+4}}

\begin{gathered}\\ \sf\longmapsto 9=5(1)+4\end{gathered}

\begin{gathered}\\ \sf\longmapsto 9=5+4\end{gathered}

\begin{gathered}\\ \sf\longmapsto 9=9\end{gathered}

\large\blue{\sf{y=-2x-8}}

\begin{gathered}\\ \sf\longmapsto 9=-2(1)-8\end{gathered}

\begin{gathered}\\ \sf\longmapsto 9=-2-8\end{gathered}

\begin{gathered}\\ \sf\longmapsto 9≠10\end{gathered}

\large\pink{\sf{y=6x-8}}

\begin{gathered}\\ \sf\longmapsto 9=6(1)-8\end{gathered}

\begin{gathered}\\ \sf\longmapsto 9=6-8\end{gathered}

\begin{gathered}\\ \sf\longmapsto 9≠-2\end{gathered}

Hence, Option B. y=5x+4 satisfies the system (1,9)

Determine the measures of angles C and D.<br>​
Morgarella [4.7K]

Answer:

c = 40 and d = 76

Step-by-step explanation:

this is going to take me a long time to explain but here we go

so you need to do 180 - 116 and get 64.

then create a equation that is like this 7y + 6 + 4y + 64 = 180

when you solve it you get y = 10

then plug in 10 in for y in 4y. and you get 40 for c

do the same for d and you will get 76

pls mark me brainleist because i didnt waster your time.

B) (y+6)^1/5 - 3

Exercise 4

A) 49^1/2 = square root of 49

(Dont have the square symbol y my phone. Lol!)

Always remember... You can write:

A^x/y = y root of A^x
