How long will it take 2000 dollars to double if it is invested at 8% interest compounded semi-annually?
The time it will take the 2000 dollar invested at 8% is t= 9.006468342 years
Compound Interest
Compound interest can be define as the addition of interest on the loan to the principal sum of the deposit.
2 = (1+8%) ^t
where t is the time of the year
2= (1 +8%)^t
2 = (1+8/100)^t
2 = ( 1 0.8)^t
Take the log of both sides
log 2 = log 1.08^t
log 2 = t log 1.08
Divide both sides by log 1.08
log 2/ log 1.08 = t
t= 9.006468342 years
Therefore, the time it will take the dollar invested at 8% is t= 9.006468342 years

Investment of $1600 at 5% interest rate for 8 years.
Investment of $1600 at 7% interest rate for 8 years.
Investment of $1600 at 7% interest rate for 12 years.
What is simple interest?Simple interest is the formula that is used to determine the interest that is earned when an amount is investment at an interest rate over a number of years.
Interest earned with simple interest increases linearly over the investment period. This means that the interest earned each year of the investment period is a constant amount.
Simple interest = amount invested x interest rate x year
Simple interest = $1600 x 0.07 x 8 = $896
Simple interest = $1600 x 0.05 x 8 = $640
Simple interest = $1600 x 0.07 x 12 = $1344

Find equation of plane pass through points (-2,1,3), (0,4,8) and (-1 ,-1,0)
The equation of plane is x + 11y + 7z - 30 = 0
What is equation?An equation is said to be a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for example, the two expressions 3x + 5 and 14 are separated by the symbol "equal."
Let ( x₁, y₁, z₁ ) ( x₂, y₂, z₂ ) ( x₃, y₃, z₃ ) be the coordinates,
we know that equation of plane is:
[tex]\left[\begin{array}{ccc}x-x1&y-y1&z-z1\\x2-x1&y2-y1&z2-z1\\x3-x1&y3-y1&z3-z1\end{array}\right][/tex] = 0

[tex]\left[\begin{array}{ccc}x+2&y-1&z-3\\0+2&4-1&8-3\\-1+2&-1-1&0-3\end{array}\right][/tex] = 0
[tex]\left[\begin{array}{ccc}x+2&y-1&z-3\\2&3&5\\1&-2&-3\end{array}\right][/tex] = 0
On solving this determinant,
(x+2) (-9+10) - (y-1) (-6-5) - (z-3) (-4-3) = 0
(x+2) - (y-1) (-11) - (z-3) (-7) = 0

The best fit line is represented by the equation y = -0.632x + 27.1, where x
represents the total bill in dollars, and y represents the percentage of the
bill left as a tip.
a. What does the best fit line estimate for the percentage of the bill left as
a tip when the bill is $15? Is this reasonable?
b. What does the best fit line predict for the percentage of the bill left as a
tip when the bill is $50? Is this reasonable?
a) The estimate for the percentage of the bill left as a tip with a bill of $15 is of 17.62%, which is reasonable.
b) The estimate for the percentage of the bill left as a tip with a bill of $50 is a non-reasonable -4.5%.
What is the line of best fit?The line of best fit in this problem is defined as follows:
y = -0.632x + 27.1.
In which the variables are defined as follows:
x is the total bill, in dollars.y is the percentage of the total bill left as a tip.Hence, for a bill of $15, the estimate is found replacing x by 15, as follows:
y = -0.632(15) + 27.1 = 17.62%.
Which is reasonable, as it is a positive number.
For a bill of $50, the estimate is obtained as follows:
y = -0.632(50) + 27.1 = -4.5%.
Which is not reasonable, as it is a negative number.

a. Find the bearing from O to A.
b. Find the bearing from O to B.
c. Find the bearing from O to C.
d. Find the bearing from A to O.
Answer:
a. 335°
Step-by-step explanation:
Bearing: The angle (in degrees) measured clockwise from north.
a. The bearing from O to A
Measure the angle from the positive y-axis, clockwise to point A.
Angles on a straight line sum to 180°, so the angle between the negative x-axis and point A is (180° - 115°).
Bearing = 270° + (180° - 115°) = 335°b. The bearing from O to B
Measure the angle from the positive y-axis, clockwise to point B.
Bearing = 270° - 48° = 222°c. The bearing from O to C
Measure the angle from the positive y-axis, clockwise to point C.
Bearing = 180° - 27° = 153°d. The bearing from A to O
Measure the angle clockwise from north of point A to point O.
Bearing = 180° - 25° = 155°A line intersects the points (4, 12) and (-1, -3). What is the slope of the line in simplest form? m = [?]

write an equation for a line parallel to y = − 2 x − 3 and passing through the point (3,-3)
Equation of line parallel to y = − 2 x − 3 and passing through the point (3,-3) is y = -2x + 3.
When two lines are called parallel?
Two lines are parallel lines if they do not intersect.
The slopes of the lines are the same.
f(x)= mx + b and g(x)= nx + c are parallel if m = n.
According to the given question:
Given equation of line is y = −2x − 3
If the new line is parallel, then it will have the same slope.
y = -2x + b
Now this line passes through the point (x,y) = (3,-3) so put in the x and y values into the equation above, solve for b
-3 = -2(3) + b
b = 3
Therefore the required equation of line is
y = -2x + 3

Two linear equations are:
2n + 3m = 280
2n + 5m = 320
Using the elimination method:
Because the coefficient for n is the same in both equations
-2m = - 40
m = 20
n = 110
