PLEASE HELP I NEED THIS WITHIN THE HOUR OR I'LL FAIL!1. Samara is adjusting a satellite because she finds it is not focusing the incoming radio waves perfectly. The shape of her satellite can be modeled by y^2=2(x+6), where x and y are modeled in inches. She realizes that the static is a result of the feed antenna shifting slightly off the focus point. What is the focus point of the satellite?A. (–5.5, 0)B. (0, –5.5)C. (0.5, 0)D. (5.5, 0) 2. Which is the standard form of the equation of the parabola that has a vertex of (–4, –6) and a directrix of y = 3?3. Franco is adjusting a satellite because he finds it is not focusing the incoming radio waves perfectly. The shape of his satellite can be modeled by y^2+6y-3x+3=0, where x and y are modeled in inches. He realizes that the static is a result of the feed antenna shifting slightly off the focus point. What is the focus point of the satellite?A. (2, –3)B. (–1.25, –3)C. (3, 2.75)D. (3, 4.75)4. What is the standard form of the equation of a parabola with a focus of (0, –3) and its vertex at the origin?

The party planning committee has to determine the number of tables needed for an upcoming event. If a square table can fit 8 people and a round table can fit 6 people, the equation 150 = 8x + 6y represents the number of each type of table needed for 150 people. The variable x represents the number of . The variable y represents the number of . If y = 9, find the value of x. The committee needs square tables.

Some of the steps in the derivation of the quadratic formula are shown. Step 4: Step 5: Step 6: Step 7: Which best explains why the expression cannot be rewritten as during the next step? Negative values, like −4ac, do not have a square root. The ± symbol prevents the square root from being evaluated. The square root of terms separated by addition and subtraction cannot be calculated individually. The entire term b2 − 4ac must be divided by 2a before its square root can be determined.

The perimeter of a rectangle is at most 80 inches. The length of the rectangle is 25 inches. The inequality 80-2w (is greater than or equal to) 50 , can be used to find w, the width of the rectangle in inches. Solve the inequality and interpret the solution. How will the solution change if the width must be at least 10 inches and a whole number? I know how to solve the equation, it is the second part I'm stumped on.

The total amount of money in a savings account after t years is given by the function A=1000(1.023)^t .How could this function be rewritten to identify the monthly interest rate?What is the approximate monthly interest rate?Drag and drop the choices into the boxes to correctly complete the table. If a value does not match, do not drag it to the table.Function Monthly interest rateA = 1000(1 + 0.023)^12tA = 1000(1.023^12)^t/12A = 1000(1.023^t/12)^12t0.23%0.19%0.31%
