Interest is the amount of money added on an amount invested. He have doubled her investment after 18 years
Compound interestThe formula for calculating the compound interest is expressed as
A = P(1+r)^t
Given the following parameters
P = $500
r = 4%= 0.04
A= $1000 (doubled)
Substitute
1000 = 500(1+0.04)^t
2 = 1.04^t
t = ln2/ln1.04
t= 17.67 = 18years
Hence he have doubled her investment after 18 years

Can someone help me answer these two questions
Answer:
C) 7=y=5x+11
B) m=-4/5, b=13/5
Step-by-step explanation:
Problem 1:
A function is linear if its slope is constant and/or its graph is straight (that means 1-degree polynomials only). Therefore, C is the only correct answer.
Problem 2:
Convert to slope-intercept form (y=mx+b):
4x+5y=13
5y=13-4x
y=13/5-4/5x
y=-4/5x+13/5
Now we can see that since the original equation is in slope-intercept form (y=mx+b), the slope, m, is -4/5, and the y-intercept, b, is 13/5, making option B the correct answer.
The slope of a line is and the y-intercept is (0, 6). What is the equation of the line in slope-intercept form?
Answer:
y=x+6

The diagonals of square DEFG intersect at H. Given that EH = 5, find the indicated measure
Answer:
3. m<GHF= 90 degrees
4. m<DGH= 45 degrees
5. HF=5
6. DE=50
Step-by-step explanation:
3. The measure of angle DGF and EFG are 45 degrees each and 45+45 is 90 degrees. When you subtract 90 from 180, you get 90.
4. A square is also a rectangle and a rectangle has four right angles and it is a rhombus and the diagonals bisect the angles. This means that angle DGH is half of angle DGF and 90/2=45.
5. The diagonals of a square are congruent so it is also 5.
6. You use the Pythagorean Theorem and 5^2 + 5^2=50
The diagonals of square DEFG intersect at H. The measure of the following option; 3. m∠GHF= 90 degrees. 4. m∠DGH= 45 degrees 5. HF=5 6. DE=50
What is the property of a square?That rectangle whose all sides are equal is called a square.
A square is always a rectangle, parallelogram, a rhombus, and a quadrilateral but its reverse statement may or may not be true.
(ie it is not always necessary that a rectangle is a square or a parallelogram is a square or a rhombus is a square).
The diagonals of square DEFG intersect at H.
Given that EH = 5, we need to find the measure of the following option;
3. The measure of ∠DGF and ∠EFG are 45 degrees each .
The sum of the angle of the bisector of diagonal 45 + 45 = 90 degrees.
When you subtract 90 from 180, you get 90.
4. A square is also a rectangle and a rectangle has four right angles and it is a rhombus and the diagonals bisect the angles.
This means that ∠DGH is half of ∠DGF
90/2 = 45.
5. The diagonals of a square are congruent so HF is 5.
6. By Pythagorean Theorem
[tex]DF^2 = 5^2 + 5^2\\\\DF = \sqrt{50}[/tex]

(2) Explain how the product of 3 and 65 could be used to find (0.03) - (0.65).*
Answer:
See Explanation
Step-by-step explanation:
Required
Explain how 3 * 65 could be used for (0.03) * (0.65)
0.03 is to 2 decimal places and 0.65 is also to 2 decimal places
In total, we have: [tex]2 + 2 = 4[/tex]
So, to get (0.03) * (0.65) from 3 * 65.
Simply calculate the product: 3 * 65
Then divide by 10 to the power of the sum of the decimal places i.e. 4
This is shown below
(0.03) * (0.65)
Express as fraction
[tex](0.03) * (0.65) = \frac{3}{100} * \frac{65}{100}[/tex]
[tex](0.03) * (0.65) = \frac{3*65}{100*100}[/tex]
[tex](0.03) * (0.65) = \frac{3*65}{10^2*10^2}[/tex]
[tex](0.03) * (0.65) = \frac{3*65}{10^4}[/tex]
