Suppose you invest $10,000 in a mutual fund that earns 6% annual interest. What is the value of your investment 30 years later? Show both the value and evidence of the thinking you used to calculate the value of the investment.
Answer:
$57400
Step-by-step explanation:
Given data
P= $10,000
R= 6%
T= 30 years
Let us Assume the investment is compounded Anually
A= P(1+r)^t
A=10000(1+0.06)^30
A=10000(1.06)^30
A=10000*5.74
A=$57400
Hence the Final Amount after 30 years compounded anually is $57400

Step-by-step explanation:
Tree A at 5 years
2x5+29=39 inches
Tree B at 5 years
5x5+14=39 inches
Answer:
★ The answer for A= 2t + 19
★ The answer for B= 5t + 14
★ So the answer would 39 inches tall which would be equal to a height after 5 years

Answer:
(13x * 10^53) + 10.
Step-by-step explanation:
To simplify the expression "13x 10^53--10" and write it using only positive exponents, we can follow these steps:
Step 1: Remove the double negative signs by converting them to positive signs:
13x 10^53 + 10
Step 2: Rewrite the expression by moving the term with a positive exponent to the denominator:
13x / (10^-53) + 10
Step 3: To simplify the denominator, we can rewrite 10^-53 as (1/10^53):
13x / (1/10^53) + 10
Step 4: Simplify the division of a fraction by multiplying by its reciprocal:
13x * (10^53/1) + 10
Step 5: Multiply 13x by 10^53:
(13x * 10^53) + 10
The simplified expression, written using only positive exponents, is (13x * 10^53) + 1

The length of the segment GH is given by the distance D = 7.3 units
What is the distance of a line between 2 points?The distance of a line between 2 points is always positive and given by the formula
Let the first point be A ( x₁ , y₁ ) and the second point be B ( x₂ , y₂ )
The distance between A and B is D , and the distance D is
Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²
Given data ,
Let the first point be G ( -9 , -4 )
Let the second point be H ( -2 , -6 )
Let the length of the segment GH = D
Now , distance between G and H is D , and the distance D is
Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²
On simplifying , we get
D = √ ( -9 - ( - 2 ) )² + ( -4 - ( -6 ) )²
D = √ ( -7 )² + ( 2 )²
On further simplification , we get
D = √ ( 49 + 4 )
D = √53
D = 7.28 ≈ 7.3 units
Hence , the distance is 7.3 units

7. Find the number of vertices of a polyhedron
having 10 faces and 12 edges
Answer:
4
Step-by-step explanation:
Using Euler's rule for polyhedra
F + V - E = 2 ( F - faces, V- vertices, E- edges )
10 + V - 12 = 2
V - 2 = 2 ( add 2 to both sides )
V = 4

Consider the graph of y = -3|xl. What will be the effect
on the graph if –3 is replaced with 3?
a. no change
b. a flip over x axis
c. vertical shift
d. horizontal shift of one unit to right
Answer:
B
Step-by-step explanation:
Essentially, the -3 in this equation is the slope, and when you multiply slope by -1 you are reflecting over the x axis.
Angle A and angle B are complementary angles. Angle A is 30 degrees. What is the measure

Zx and Zy are supplementary angles. Zy measures 108°,
What is the measure of Zx?
Stuck? Watch a video or use a hint.
Answer:
72°
Step-by-step explanation:
Given
Zy = 108°
Zx = ?
We know
Zx + Zy = 180° {being supplementary angles }
Zx + 108° = 180°
Zx = 180° - 108°
Zx = 72°

The endpoints of line segment CD are C(-2,0) and D(4,9). Find the midpoint of
line segment CD
Given:
The endpoints of line segment CD are C(-2,0) and D(4,9).
To find:
The midpoint of CD.
Solution:
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Using the midpoint formula, the midpoint of CD is
[tex]Midpoint=\left(\dfrac{-2+4}{2},\dfrac{0+9}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{2}{2},\dfrac{9}{2}\right)[/tex]
[tex]Midpoint=\left(1,4.5\right)[/tex]
Therefore, the midpoint of the line segment CD is (1,4.5).
