Use this formula: A = P(1 + r/n)^nt, where A is the amount after interest (what you are solving for), P is the amount you invested originally, r is the rate at which it was invested in decimal form, n is the number of times the compounding occurs each year, t is the time in years it is invested. It would look like this: A = 500(1 + [.06/12])^12*5. Do inside the parenthesis first to get 1 + .005 = 1.005. Now raise that to the 60th power (12 times 5 is 60) to get 1.34558. Now multiply that by the 500 out front to get a total amount of $674.43
The equation would be:
y = 3x + 15
1) Table: It is pretty easy to do so, just plug in 0, 1, 2, 3, etc. for x and solve for y
2) graph (find slope): slope would be 3 shells/day that has a y-intercept of 15
3) you already defined the variables
4) 3(5)+15 = 15+15 = 30 seashells
I hope this helps!
the fraction in the image is 2 1/2
let's try each choice
1) 2/3 x 5/2 = 10/6 = 5/3
2) 5/4 x 5/2 = 25/8
3) 3/3 x 2 1/2 = 2 1/2
4) 4/5 x 5/2 = 20/10 = 2
who is giving you these questions?
Answer:
the graph will start at y1 and go down 1 and right 2 for every point.
Step-by-step explanation: since the x is negative you know that the graph is going to be negative so from left to right it will be going from top to bottom. next you look at the 1/2 which just states that every point on that line will will be 1 down and two right from the previous point. now you look at the +1 which just says that the graph will cross the y axis a 1.
Right Triangles and the Pythagorean Theorem
The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
The side opposite the right angle is called the hypotenuse (side c in the figure).
