Answer:
$64,269.65
Step-by-step explanation:
Lets use the compound interest formula provided to solve this:
![A=P(1+\frac{r}{n} )^{nt}](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7Br%7D%7Bn%7D%20%29%5E%7Bnt%7D)
<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, change 6.25% into a decimal:
6.25% ->
-> 0.0625
Since the interest is compounded quarterly, we will use 4 for n. Lets plug in the values now:
![A=10,000(1+\frac{0.0625}{4})^{4(30)}](https://tex.z-dn.net/?f=A%3D10%2C000%281%2B%5Cfrac%7B0.0625%7D%7B4%7D%29%5E%7B4%2830%29%7D)
![A=64,269.65](https://tex.z-dn.net/?f=A%3D64%2C269.65)
The value of Sara's investment after 30 years will be $64,269.65
Step by step explanation:
X + y=25
-y. -y
X=25-y
3x +4y= 90
3(25-y) =90
75-3y=90
-75. -75
-3y =15
/-3. /-3
Y=-5
X=25-(-5)
X= 25+5
X=30
Answer:
for the first equation
f(-3) = 34
f(4) = 6
for the 2nd equation
f(-3) = -56
f(4) ÷ 70
Step-by-step explanation:
my work is attached in a picture.
all you do is substitute each x value into each equation
<span> line passes through the points (p, a) and (p, –a)
where p and a are real numbers and p ≠ 0
(p, a) and (p, –a) m = Cannot divide by ZERO, there is no slope to this Line.
slope of the line: no slope (does not exist)
equation of the line: x = p Perpendicular Line
</span><span>slope of a line perpendicular to the given line: would be m = 0, horizontal Line y= 3
</span>y- intercept: none
