Answer:

t(99)= -2.89

Step-by-step explanation:

-To places after the decimal point is equivalent to rounding off to the nearest hundredth.

-To round off to the nearest hundredth, we check the thousandths digit:

  • If the thousandths digit is less than5, we round down to the previous hundredth.
  • If the thousandths digit is greater than 4, we round up to the next hundredth:

Hence,-2.8888\approx-2.89

What is the y-intercept of the equation of the line that is perpendicular to the line y =
igor_vitrenko [27]

Answer:

y=-5/3x+20

Step-by-step explanation:

Let the equation of the required line be represented as \[y=mx+c\]

This line is perpendicular to the line \[y=\frac{3}{5}x+10\]

\[=>m*\frac{3}{5}=-1\]

\[=>m=\frac{-5}{3}\]

So the equation of the required line becomes \[y=\frac{-5}{3}x+c\]

This line passes through the point (15.-5)

\[-5=\frac{-5}{3}*15+c\]

\[=>c=20\]

So the equation of the required line is \[y=\frac{-5}{3}x+20\]

Among the given options, option 4 is the correct one.

2p^2 -1 =7 <br> Would appreciate some help thank you
SIZIF [17.4K]

Answer: p = 2

Step-by-step explanation:

To solve this problem, you first have to add 1 to each side of the equation, leaving you with 2p^2 = 8. Then you divide by 2 on both sides leaving you with p^2 = 4. After that, you take the square root of both sides, and because 4 is a perfect square, you get p = 2 as your final answer.
