I'm not sure about ratios, because I'm bad at them myself, but I can help you with graphs. Take this plot point, for example (3,4) The X-axis is the line that is horizontal. This is the first letter in the coordinates, 3, so you would find the number 3 on the X-axis. The Y-axis is the line that is vertical, and its number is the second one in your set of coordinates. You would then find 4 on your Y-axis. Then, draw a line from your X-coordinate up, and your Y-coordinate right. Find where these overlap. If these are negatives, however (for example, if the coordinates were (-3,-4)), then draw the line in the opposite direction (X-coordinate down, Y-coordinate left) and do the same as you would with normal coordinates and find where they overlapped. I hope this helped you, since I love graphs and want to help!

In Exercise,find the balance in the account after 10 years.

djverab [1.8K]

Answer: The balance in the account after 10 years is $3374.65

Step-by-step explanation:

The exponential equation for growth [ compounded continuously] is

$y=pe^{rt}$

, where P= Present value

r= growth rate ( in decimal)

t= time (years)

By considering the given information , we have

p=$2500 r = % =0.03 and t= 10

Substitute all the values in the above equation , we get

$y=2500e^{0.03(10)}$

$y=2500e^{0.3}$

$y=2500(1.3498588)=3374.64701894\approx3374.65$ [Round to the nearest cent]

Therefore, the balance in the account after 10 years is $3374.65

Simplify. 2(m + 11) 0 24 m O 2 m+ 22 O 2 m+ 11 O 22 m

krek1111 [17]

Answer:

2m + 22

Step-by-step explanation:

Use the distributive property.

2(m + 11)

2 x m = 2m

2 x 11 = 22

Therefore, 2m + 22

True or false 120% of a whole number is always greater than the number? and why?

Stells [14]

I can only use math to explain it. What is 100%?
100% = $\frac{100}{100}$
percent means per 100.
so 120% = 120/100 = 1.2
120% of a whole number. For example 120% * 10 = $\frac{120}{100} * 10$ = 12
is it greater than 10.

How do you do simplify this -9 -11

zheka24 [161]

Answer:

-9 + -11=-20

Step-by-step explanation:

Since subtracting is the same as addition of the oppositie, just putting a negative symbol is easier because you are only working with negative numbers, instead of one negative and one positive.

Did that help?
