Answer:

New balance = 3640

Step-by-step explanation:

Given the following data;

Interest rate = 4% = 4/100 = 0.04

Principal = 3500

To find the new balance;

First of all, we would find the amount at the interest rate;

New amount = interest rate * principal

New amount = 0.04 * 3500

New amount = 140

Now, to find the new balance;

New balance = principal + new amount

New balance = 3500 + 140

New balance = 3640

irakobra [83]

Answer:

The required interval is (26.23 , 27.37)

Step-by-step explanation:

The mean is = 26.8

The standard deviation is = 7.42

n = 654

At 95% confidence interval, the z score is 1.96

To find the desired interval we will calculate as:

$26.8+1.96(\frac{7.42}{\sqrt{654} } )$

And $26.8-1.96(\frac{7.42}{\sqrt{654} } )$

$26.8+0.57$ and $26.8-0.57$

= 27.37 and 26.23

So, the required interval is (26.23 , 27.37)

bogdanovich [222]

Step-by-step explanation:

Length of third side

$= \sqrt{ {24}^{2} + {16}^{2} } \\ = \sqrt{576 + 256} \\ = \sqrt{832} \\ = 28.84 \\ \approx \: 28.8 \: in$

Length of third side

$= \sqrt{ {24}^{2} - {16}^{2} } \\ = \sqrt{576 - 256} \\ = \sqrt{320} \\ = 17.8885438 \\ \approx \: 17.9 \: in$

Find g(x), where g(x) is the translation 4 units up of f(x) = x2.

NNADVOKAT [17]

Answer:

$g(x)=1(x-0)^{2}+4$

Step-by-step explanation:

Given:

The function, $f(x)=x^{2}$

A standard parabola with vertex at origin is represented as:

$f(x)=ax^{2}$

The above function is a standard parabola with vertex at origin and opening upward.

The vertex of the above function is at the origin $(0,0)$ and the value of $a$ is 1.

Now, the function is translated 4 units up.

So, from the rule of function transformations, if a graph is moved up by $c$ units, then $c$ units is added to the function.

Therefore,

$g(x)=f(x) + 4\\g(x)=x^{2}+4$ .

Also, the vertex of $f(x)$ will be translated 4 units up. So, the co-ordinates of the vertex of $g(x)$ will be $(0,0+4)=(0,4)$

Now, express the above function in the vertex form $g(x)=a(x-h)^{2}+k$ .

We have $a=1,h=0,k=4$

This gives,

$g(x)=1(x-0)^{2}+4$
