Answer:

Investment amount after 9 years = 14715.12$

Explanation:

It is given to use continuous change function, $A(t) = Pe^{rt}$

Here P = Principal = 10500$

r = Rate of increase = 0.0375

t = Number of years = 9

$A(t) = Pe^{rt}\\ \\ A(t) = 10500*e^{0.0375*9}=14715.12$

So, investment amount after 9 years = 14715.12$

A coin is tossed and an eight-sided die numbered 1 through 8 is rolled. Find the probability of tossing a head and then rolling

ratelena [41]

Answer: 7/8

Step-by-step explanation:

Probability is calculated by number of possible outcomes/ total outcomes

From the question, a coin only has two sides, Head or Tail. Total outcomes is therefore equal to 2

Possible outcome is to toss a head, which is one event

Probability of tossing a head is therefore =1/2

The second part of the question is rolling a die with eight sides.

Here, the die is said to have eight sides, 1,2,3,4,5,6,7,8. Total outcomes is therefore equal to 8

Possible outcome of rolling a number greater than 5 is 3 possibilities, that is rolling 6, 7 and 8.

Pr(rolling > 5) is 3/8

Therefore, Pr ( head; rolling > than 5)

= 1/2 + 3/8

=7/8

I hope this is clear, please mark as brainliest answer

Kent thinks that x+x and x2 are equivalent expressions because they each have a value of 4 when x=2. Which statement best demons

Kevin is incorrect because x+x is adding two numbers, but x^2 is multiply.

1. -10+4 =<br> 2. -7+11=<br> 3. -8+7=

Setler [38]

1. -6

2. 4

2. -1

The positive numbers will out rule the negative number. It's sort of like placing blocks over another set of blocks. :)

HELP.... please??????????????

Answers:

Functions

y = -x+11
y = 2x^2-6x+4
y = -7

Not functions

x = 3
x^2+y^2 = 81
y^2 = -5x-12

=======================================================

Explanation:

A function is possible if and only if any given x input leads to exactly one y output.

For something like x^2+y^2 = 81, we can see that x = 0 leads to either y = 9 or y = -9. So this would <u>not</u> be a function. We would need x to pair with only y value to have it be a function.

We have the same thing going on with y^2 = -5x-12 as well.

For anything of the form x = k, where k is any real number, this is also not a function. We have one single input only and it leads to infinitely many outputs. So in a sense, this is even worse compared to the other examples.

-----------------

In summary, we have these three non-functions:

x = 3
x^2+y^2 = 81
y^2 = -5x-12

Everything else is a function. You can use the vertical line test as a visual way to check.
