<h3><u>Answer:</u></h3>

The number of x-intercepts of the function are:

Two(2)

<h3><u>Step-by-Step explanation:</u></h3>

The domain of a quadratic function is all real numbers and the range is y ≤ 2.

i.e. the graph of this quadratic polynomial will be a downward parabola whose vertex has y-coordinates less than or equal to 2.

Also we know that any upward or downward facing parabola have two x-intercepts i.e. the  parabola crosses the x-axis at two points i.e. the y-coordinates of those two points are zero.

Hence, the number of x-intercepts of the function is:

Two(2)

Compound Interest: You deposit $100 in an account that earns 3% annual interest compounded continuously. How long does it take t
monitta

9514 1404 393

Answer:

  a) 3.18 years

  b) 13.52 years

  c) 23.10 years

Step-by-step explanation:

Solving for t, we find ...

  A = Pe^(rt)

  A/P = e^(rt)

  ln(A/P) = rt

  t = ln(A/P)/r

For P=100 and r=.03, the times are ...

a. $110: t = ln(110/100)/.03 ≈ 3.18 years

b. $150: t = ln(150/100)/.03 ≈ 13.52 years

c. $200: t = ln(200/100)/.03 ≈ 23.10 years

translate this into an expression: the quotient of a number, x, and 8, could you please explain it to me?​
Xelga [282]

Answer:

x/8

Step-by-step explanation:

First, we are given "the quotient of...". This means that we are dividing something/something else. If two numbers are given in the phrase "something and something else", the first number given will be the something, and the second number will be the something else.

The first number listed is x. Therefore, we have

x/something else.

Next, we are given "and 8", so we have x/8 as our expression

In a plane, if two lines are each parallel to a third line, then they are _________ to each other.
iogann1982 [59]
Parallel. This is pretty simple if you either a) Picture it in your head, or b) look at each option logically. lets try out b)

The last option does not really apply to lines, and is for angles. (unless your talking about the adjecent sides of an angle, but this would mean they meet at a vertex) Perpendicular, doesnt make sense because if they were perpindicular on a plane, (2-d) then it would be immpossible for BOTH to be parallel to a third line. This leaves the first option, which makes sense.
