Answer:

  P(x) = -1.1x +49

Step-by-step explanation:

You are given the percentage in 2000 (for x=0) as 49, and told that its rate of change is -1.1 percent per year. So, with a slope of -1.1 and an intercept of 49, the slope-intercept form of the linear equation becomes ...

Ashely is making $500 a week at her job. She receives a 20% pay raise. A year later she takes a 5% pay cut. How much money does
zheka24 [161]

Answer:

<em>$570 a week</em>

Step-by-step explanation:

<u>Percentage Calculations </u>

One tricky fact about percentages is that they are usually performed over the last computed quantity. It makes them non-additive. For example, a raise of 10% followed by a 10% some time later, is NOT a 20% of total raise

The question states Ashely is making $500 a week at her job and that she receives a 20% pay raise. After that raise she will make

\$500*(1+20/100)=\$500(1.2)=\$600 \text{ a week}

A year later she takes a 5% pay cut. We must be careful to take that percentage from the last earnings. She now makes

\$600(1-5/100)=\$600(0.95)=\$570\ a\ week

A 0.02 N push accelerates a table-tennis ball along a table at 8 m/s2 north. What is the mass of the ball?
photoshop1234 [79]
  • Force=0.02N=F
  • Acceleration=a=8m/s^2
  • Mass=m

According to Newton's second law

\\ \sf\longmapsto F=ma

\\ \sf\longmapsto m=\dfrac{F}{a}

\\ \sf\longmapsto m=\dfrac{0.02}{8}

\\ \sf\longmapsto m=0.0025kg

\\ \sf\longmapsto m=2.5g
