You deposited $3,000 in the bank in 2019. It is compounded annually at 4%. How much money will you have in 9 years (in 2028)?
ANSWER
[tex]\begin{equation*} \$4,269.94 \end{equation*}[/tex]EXPLANATION
To find the amount of money that you will have in 9 years, apply the formula for annually compounded amount:
[tex]A=P(1+r)^t[/tex]where P = principal
r = interest rate
t = number of years
Hence, the amount after 9 years is:
[tex]\begin{gathered} A=3000(1+\frac{4}{100})^9 \\ A=3000(1+0.04)^9=3000(1.04)^9 \\ A=\$4,269.94 \end{gathered}[/tex]That is the answer.

Answer:
1.48
Step-by-step explanation:
Subtract 14 from 32 giving us 18. Showing us that 18 is the amount of girls in the class.
Then do 32 x 1.515 which gives us 48.48
multiply the 14 x 1.56 = 21.84
then do 48.48 - 21.84 =26.64
then do 26.62 divided by 18
which gives us 1.48.
Which of the following is the average rate of change over the interval [−3, 0] for the function g(x) = log2(x + 4) − 5? (2 points)
The average rate of change of g(x) on the interval [-3, 0] is r = 2/3.
How to get the average rate of change?
For any function f(x), we define the average rate of change on an interval [a, b] as:
r = ( f(b) - f(a))/(b - a)
In this case, the interval is [-3, 0], and the function is:
g(x) = log₂(x + 4) - 5
Replacing that in the average rate of change formula, we get:
r = ( g(0) - g(-3))/(0 + 3)
g(0) = log₂(0 + 4) - 5 = -3
g(-3) = log₂(-3 + 4) - 5 = -5
Replacing that:
r = (-3 + 5)/3 = 2/3
The average rate of change is 2/3.

The vivandière sold viands and sandwiches. If she sold 300 total and 50 more viands than sandwiches, how many of each did she sell?
She sold 125 sandwiches and 175 viands as per the equation using substitution method as the definition of substitution method says, "The algebraic approach to solving simultaneous linear equations is known as substitution method. The value of one variable from one equation is substituted in the other equation in this method, as the name implies".
How to construct equation?A mathematical formula is an equation that uses algebraic operations like add, subtract, multiply, divide, raise to a power, take the natural logarithm, take the cosine, or some combination of operations to express one variable as a combination of other variable(s). One-step equations can be solved in four different ways: by adding, subtracting, multiplying, and dividing. In an equation, both sides will remain equal if we add the same amount to each side. The "scale" (or equation) must ALWAYS be balanced when solving math equations so that both sides are ALWAYS equal.
Here,
Let x be the sandwiches she sold and y be the viands she sold.
x+y=300
y=50+x
x+50+x=300
2x+50=300
2x=250
x=125
y=50+125
y=175
In accordance with the equation and applying the substitution method, she sold 125 sandwiches and 175 appetizers "The substitution method is an algebraic strategy for resolving simultaneous linear equations.

If P = (-1,5), Find:Ry=1 (P)([?], []).
The line y = 1 is a horizontal line and thus is a line that is parallel to the x-axis.
If we reflect about a line that is parallel to the x-axis, then the x-coordinate of the point (that is reflected) will remain the same, thus the image of (-1, 5) has x-coordinate -1 and thus the point is of the form (-1, b).
The point (-1, 5) is 4 units from the line y = 1 (because the difference between y = 5 and y = 1 is 4).
The reflected point has to be the same distance from the line y = 1 as the original point

∡BCA = 29
∡BOC = 58
Explanation:
The angles BDC and BAC form the same arc on the circle, the arc BC. Then, these angles have the same measure, so
∡BCA = ∡BDC
∡BCA = 29
Then, we can use the inscribed angle theorem to find the arc BC as follows
[tex]\begin{gathered} \measuredangle BDC=\frac{1}{2}BC \\ \\ 29=\frac{1}{2}BC \\ \\ 2(29)=BC \\ \\ 58=BC \end{gathered}[/tex]Therefore, arc BC has a measure of 58 degrees, which means that ∡BOC is equal to
∡BOC = Arc BC
∡BOC = 58
So, the answers are
∡BCA = 29
∡BOC = 58

What is the difference between Distance and Displacement?
While distance and displacement appear to signify the same thing, they actually have very different definitions and meanings.
A scalar quantity known as distance measures "how much ground an object has traversed" while moving.
An object's total change in position is referred to as displacement, a vector variable that measures "how far out of place an object is."
Distance is the sum of an object's movements, regardless of direction. Regardless of an object's starting or ending position, distance can be defined as the amount of ground it has covered.
The term "displacement" refers to a shift in an object's position. It is a vector quantity with a magnitude and direction. The symbol for it is an arrow pointing from the initial location to the ending place. For instance, if an object shifts from location A to position B, its position changes. Displacement is the term used to describe this shift in an object's position.
∠BCD = 36°
∠ACD = 32°
CD= 26m
tan∠BCD=0.726
tan∠ACD=0.624
since,
BD=CD x tan∠BCD
AD=CD x tan∠ACD
thus,
AB = BD-AD
= CD x tan∠BCD - CD x tan∠ACD
= CD x [0.726 - 0.624]
