Answer:

The rate of change will be the same for all years.

Step-by-step explanation:

As it is mentioned in the question, that the rate of change is 7%.

And as we know that

= I (1 + R)^T

where

I = Initial amount

R = Rate of growth,

And T = Time.

So in the given case, the rate is 0.07, or 7% while on the other hand the growth RATE remains constant and the growing amount would be increased each year.

Therefore the rate of change would be the same for all the year

In an investment account what if $2000 is invested. What is the value after 3 years if compounded monthly by 6% ?
OleMash [197]
<span>
Compound interest formula  A = P(1 +r/100)^n
A = Amount
r = rate = 6
n = number of compounding time.
P = Principal = $2000.
Since we are compounding monthly, r = 6% p.a = (6/12)% per month.
n= 3 years = 3*12 = 36 months.
Note that  since we are compounding monthly, our time would be in months.
A = P(1 +r/100)^n
A = 2000 * (1 + (6/12)/100 )^36
A = 2000 * (1 +  6/1200)^36
</span><span>A = 2000 * (1 +  0.005)^36    Use your calculator</span>
<span> <span>A = 2000 * (1 .005)^36</span> = 2393.36
Amount = $2 393.36</span>
That's it. Cheers.

If x&lt;5 and y&lt;6, then x+y__ 11<br> is it &lt;,&gt;,=?
Daniel [21]
To solve for this, let's try the highest number x and y can be.

X < 5, so it can be 4.
Y < 6, so it can be 5.

4 + 5 = 9.
9 < 11, so x + y < 11.

Your missing inequality symbol is:

<

I hope this helps!

Which is a possible turning point for the continuous function f(x)? (–2, 0) (0, –2) (2, –1) (4, 0)
alekssr [168]

We are given coordinates of a continuous function f(x)

(–2, 0)

(0, –2)

(2, –1)

(4, 0).

We need to find the possible turning point for the continuous function.

<u>Note: Turning point is a point on the graph where slope of the curve changes from negative to positive or positive to negative.</u>

<em>A turning point is always lowest or highest point of the curve (where bump of the graph seen).</em>

For the given coordinates we can see that  (–2, 0) and (4, 0) coordinates are in a same line, that is on the x-axis.

But the coordinate  (0, –2) is the lowest point on the graph.

Therefore, (0, –2) is the turning point for the continuous function given.

A figure is shown Below<br><br> Find M
yKpoI14uk [10]

Answer:

58 degrees

Step-by-step explanation:

We know that angles on a straight add up to 180 degrees. Therefore:

To find the angle at the top of the triangle do 180-112 = 68

To find the angle at the right side of the triangle do 180 - 126 = 54

We know that angles in a triangle add up to 180 degrees. Therefore:

To find m do 180 - (54 + 68) = 58
