Please do it

For images please try have them be pdfs or jpegs. If that is an issue let me know and we can resolve it. 1a) (4 points each) Pick a negative number m for a slope and a point in the plane. Find an equation of the line with the chosen slope that passes through the chosen point. 1b} Write an equation for a line with slope 10 and that passes through the point you chose. 1c) Find the equation of a line perpendicular to the one in 1a) and that passes through the point {3.5) 2} (10 points} If growth of a particular type of radioactive material is modeled by an exponential function. There are initially 1000mg present and the amount halves every hour. a) How long until it has 1/8 of its initial value? b) How long until it has 100mgs left? 3) (10 points)Graph x2 x 30. Find the x-intercept(s) and y-intercepts algebraically. Show your work. Then Graph 4) ( 10 points)Distribute and simpli): (5 + x - 3x2 + 4x3)(2x - 4) 5) ( 10 points)Distribute and simply}: (5 +1) (3-65) 6} Evaluate the given function. Show your work. 3 f(x) = 3x3 +4x 10 amigos) = _Zx+5 a) f(1)= b) M) = Cl HEP d) 90:) =21. Find it. 7) (10 points) If the money in a special account increases by 10% each year and there is $500 initially present. Create a table that models it for the first 3 years and a function that models it. a} When will the account be worth $1000? 8} The value of a certain jewel's price can be modeled by a linear equation from the time it is purchased. 3 years after it is purchased it is valued at 518000. At 10 years after purchase it is worth $25000. a) Find the y-intercept: What does it mean in the context of this problem. b) How much will it be worth 100 years after purchase? c) Find the x-intercept. Does it mean anything in the context of the problem? Explain. d) How many years after purchase will it be worth $20,000. 9) If growth of a particular type of bacteria is modeled by an exponential function. There are initially 100 present and the amount triples every hour. Write an equation that represents this and define your variables. How long until there are 5000
