Answer:

  16% increase

Step-by-step explanation:

A percentage change can be calculated from ...

  percentage change = ((new value)/(old value) -1) × 100%

  = (58/50 -1) × 100% = (1.16 -1) × 100%

  = 16%

Mr. Key's work hours increased 16% from last week to this.

Enter the equation of the line in slope-intercept formSlope is -4, and (6,1) is on the line.The equation of the line is
lianna [129]

Equation of a line in slope-intercept form:

y=mx+b

m is the slope

b is the y-intercept

As you have the slope (m= -4) and a point (6,1) you use it in the equation above to find the y-intercept, as follow:

(6,1) x=6 y=1

m= -4

1=-4(6)+b

Solve b:

\begin{gathered} 1=-24+b \\  \\ 1+24=-24+24+b \\ 25=b \end{gathered}Then, the equation of the given line in slope-intercept form is:y=-4x+25

What do I have to major in to become an astronomer and approximately how long would I have to stay in college?
Aleonysh [2.5K]
Something like physics, you want to not have such a specific major because you can always change your mind later on. It might take around 10ish years, but that is a rough estimate.

An object, which is at the origin at time t=0, has initial velocity V0= (-14.0i - 7.0j)m/s and constant acceleration a=(6.0i + 3
sesenic [268]
I am pretty sure the first thing we should do is to <span>integrate acceleration into velocity
And we will have: </span>a(t) = \ \textless \ 6,3\ \textgreater \v(t) = \ \textless \ (6t+C),(3t+C)\ \textgreater \ ; where    -- v(0) = \ \textless \ -14,-7\ \textgreater \
Then calculate v :&#10;v(t) = \ \textless \ (6t-14),(3t-7)\ \textgreater \
As you can see, velocity is zero and none of the objects is moving. It happens when <span> t=7/3 which means we can calculate this in the way we did (integrating) :
</span>p(t) = \ \textless \  (3t^2-14t+C) , ((3/2)t^2-7t+C) \ \textgreater \ &#10;
The product is <span>p(0) = 0 that makes us to reduce vector function to</span>p(t) = \ \textless \  (3t^2-14t) , ((3/2)t^2-7t) \ \textgreater \   where t = 7/3p(7/3) = \ \textless \  -49/3 , -49/6 \ \textgreater \<span>
