If Julie invests $9,250 at a rate of 7%, compounded weekly, find the value of the investment after 5 years. $13,455.78
STatiana [176]
What is that $13,455.78? Something? I did this and got $13,122.76.  Here's how I did it:
Use this formula
A=P(1+ \frac{r}{n} ) ^{(n)(t)} where A is the ending amount, P is the starting amount, n is the number of times it compounds a year, and t is the number of years.  We have all we need to set it up:
A=9,250(1+ \frac{.07}{52} ) ^{(52)(5)}
First divide and add inside the parenthesis:
A=9,250(1.001346) ^{(52)(5)}
then multiply the exponents:
A=9,250(1.001346) ^{260}
raise the value inside the parenthesis to the power of 260:
A=9,250(1.418676)
and finally multiply to get A = $13,122.76

Give the general form of the equation of the line through (1,2) and is perpendicular to the line passing through (-6,-3)(6,3)
olga nikolaevna [1]

Answer:

4x+3y-10=0

Step-by-step explanation:

first find the gradient of the line that is perpendicular to the line of interest.

y2-y1/x2-x1

3--3/6--6

=3+3/6+6

=9/12

3/4

The gradient of the line of interest is the negative reciprocal of 3/4. Therefore m is -4/3

next, substitute information into

y-y1=m(x-x1)

y-2=-4/3 (x-1)

multiply both sides of equation by 3

3y-6=-4 (x-1)

expand brackets

3y-6=-4x+4

rearrange in general form

4x+3y-10=0

6. Find the equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel
prisoha [69]
<h3><u>The equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel  to the line -5x + 4y = 8 is:</u></h3>

y = \frac{5}{4}x + 13

<em><u>Solution:</u></em>

Given that,

We have to find the equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel  to the line -5x + 4y = 8

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c

Where "m" is the slope of line

From given,

-5x + 4y = 8

Rearrange to slope intercept form

4y = 5x + 8

y = \frac{5x}{4} + \frac{8}{4}\\\\y = \frac{5x}{4} + 2

On comparing the above equation with slope intercept form,

m = \frac{5}{4}

We know that, slopes of parallel lines are equal

Therefore, slope of line parallel  to the line -5x + 4y = 8 is:

m = \frac{5}{4}

\text{Substitute } m = \frac{5}{4}\ and\ (x, y) = (-8, 3) \text{ in eqn 1}

3 = \frac{5}{4} \times -8 + c\\\\3 = -10 + c\\\\c = 13

Substitute c = 13 and m = 5/4 in eqn 1

y = \frac{5}{4}x + 13

Thus the equation of line in slope intercept form is found
