If ?2000 is placed into a bank account that pays 3% compound interest per year , how much will be in the account after 2 years ?

Mathematics
1 answer:
Elodia [21]3 years ago
3 0

Answer:

Step-by-step explanation:

A=P(1+r/n)^t*n

A=2000(1+.03)^2

A=2000(1.03)^2

A=2000(1.0609)

A=2121.80

Since it’s per year I didn’t divide 1 by .03 or multiply it by 2 since it would end in the same equation. If you were to do semiannually or any other payment period, the process would have been nessassary.

Hope this helps!

Tell whether the graph of the Quadratic function y=-3x squared +x+1 opens upward or downward
8_murik_8 [283]

Answer:

down

Step-by-step explanation:

y = -3x^2 +x +1

The coefficient of the x^2 term is negative so it opens facing down

X^2 coeffient

- means down

+ mean up

Help please 1. Describe the transformations necessary to transform the graph of
natta225 [31]

Here are all the steps, and what they do:

STEP 1: HORIZONTAL TRANSLATION

We transform

x^2\mapsto (x-1)^2

The general transformation is

f(x)\mapsto f(x+k)

These transformations translate the graph horizontally, k units to the left if k>0, k units to the right if k<0.

In this case, k = -1, so we translate the original graph 1 unit to the right.

STEP 2: VERTICAL STRETCH

We transform

(x-1)^2\mapsto 3(x-1)^2

The general transformation is

f(x)\mapsto kf(x)

These transformations stretch the graph vertically. The graph expands if |k|>1, while it shrinks if 0<|k|<1. If k is negative, we also reflect the graph with respect to the x axis.

In this case, k = 3, so we stretch the graph vertically by a factor 3.

STEP 3: VERTICAL TRANSLATION

We transform

3(x-1)^2\mapsto 3(x-1)^2+4

The general transformation is

f(x)\mapsto f(x)+k

These transformations translate the graph vertically, k units up if k>0, k units down if k<0.

In this case, k = 4, so we translate the graph 4 units up.

So, we start from the original graph of f(x)=x^2 and we:

  • Translate it 1 unit to the right
  • Stretch it vertically by a factor 3
  • Translate it 4 units up

(the order is important!)

to get the graph of g(x)=3(x-1)^2+4

4(2y-7)=64+12y<br> 2y-7=16+3y<br> 5y=23<br> Y=4.6<br> Is this equivalent? <br> (Explain)
ratelena [41]
Yes it is equivalent because you need to isolate the y so divide by 5 on both sides and 23 divided by 5 is 4.6

Find in degrees.<br> 11<br> B<br> 6<br> [?]°<br> Round to the nearest hundredth.<br> Enter
avanturin [10]

Answer:

\beta  = 28.610

Step-by-step explanation:

in this case we have a right angled triangle, whenever you see this triangle think of the TRIG RATIOS * sin, cos & tan* but if it was another triangle besides right angled triangle you use SINE RULE OR COSINE RULE

SOLUTION

\tan( \beta )  =  \frac{opposite}{adjecent}  \\  \tan( \beta )  =  \frac{6}{11}  \\  \beta  =  tan(inverse)( \frac{6}{11} ) \\  \beta  = 28.61045
