Answer:
$2,753.79
Step-by-step explanation:
Compound Interest Formula
[tex]\large \text{$ \sf A=P\left(1+\frac{r}{n}\right)^{nt} $}[/tex]
where:
A = final amountP = principal amountr = interest rate (in decimal form)n = number of times interest applied per time periodt = number of time periods elapsedGiven:
P = $2,000r = 3.25% = 0.0325n = 1t = 10Substitute the given values into the formula and solve for A:
[tex]\implies \sf A=2000\left(1+\frac{0.0325}{1}\right)^{(1 \times 10)}[/tex]

There are numbers that are terms in both the sequence S and the sequence T.
Find one of these numbers.
Answer:
t=4+6n
Step-by-step explanation:
a = 10
d=6
in general
tn = a + (n-1)*d
tn = 10 + (n-1)*6
tn = 10 + 6n - 6
tn = 4 + 6n

5x³ + 2 , when x = -1
5(-1)³ + 2
= -5 + 2
= -3
Answer:
-3
(first option listed)
Step-by-step explanation:
we know that 5x³ + 2 is our expression
we want to "evaluate" (find/solve for) when x = -1
we can do this by plugging in -1 to the expression:
5x³ + 2 {note, x = -1}
5(-1)³ + 2 {-1³ = -1}
5(-1) + 2
(-5) + 2
-5 + 2 = - 3
so, when x = -1, the statement is equivalent to -3

Explain how to find the average rage of change for a function over a given interval.
The average rate of change for a function over an interval is the slope
How to explain the steps?Take for instance, we have the function to be
Function f(x)
And the interval is (a,b)
The average rate of change for the function over the interval is
Rate = (f(b) - f(a))/(b - a)
The above represents the slope
Take for instance, we have:
f(x) = x^2 [2, 4]
We have:
f(2) = 2^2 = 4
f(4) = 4^2 = 16
So, we have:
Rate = (16 - 4)/(4 - 2)
Rate = 6

the top is 26 bottom is 24 left side is the missing side
Answer:
The answer is B=10 and the top is called hypothenus
Answer:
x = 10
Step-by-step explanation:
The given is a right triangle, in right triangles the sum of square value of two legs (base and height) is equal to square value of hypotenuse.
Now, know the value of base and hypotenuse are 24 and 26
let x represent the missing side:
26^2 = x^2 + 24^2
676 = x^2 + 576 subtract 576 from both sides
100 = x^2 find the root of both sides
10 = x this is the length of the missing side

The cost of the fruit is given by the function y = 3x + 1, where x is the number of fruits and y is the total cost. Find the range of the function.
The range of the given function will lie from ( -0.333,0) to ( 0,1).
What is the range?A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
Given that:-
The cost of the fruit is given by the function y = 3x + 1, where x is the number of fruits and y is the total cost.When we plot the graph of the function we will see that the straight line will cut the x-axis at point (-0.333 ) and the y-axis cut at ( 0,1 ) the points between the two points will be the solutions of the equation.

Find the equation of the line through point (8,−9) ( 8 , − 9 ) and perpendicular to 3+8=4 3 x + 8 y = 4 .
The equation of the line will be 3y + 8x = 165.
What is an equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that:-
Find the equation of the line through point (8,−9) ( 8, − 9 ) and perpendicular to 3 x + 8 y = 4.The given equation of the line is:-
3 x + 8 y = 4.
The slope of this line will be:-
3 x + 8 y = 4.
8y = -3x + 4
y = -3 /8x + ( 1 / 2)
y = mx + c
m = -3 / 8
Since the line is perpendicular to the other line 3x +8y = 4 so the slope will be inverse and negative for the line.
So the slope of the line will be -8 / 3
The equation of the line passing through the point will be given as:-
y - y 1 = m ( x- x1)
y - (-9) = ( -8 / 3) ( x - 8)
Y + 9 = ( -8 / 3 ) ( x -8 )
3 y = -8x + 165
3y + 8x = 165
Therefore the equation of the line will be 3y + 8x = 165.

f(x)=√x - 8. Find f¹(x) and its domain.
A. f¹(x) = x² +8; x≥ −8
-1
OB. f¹(x) = x² +8; x20
O c. f¹(x) = (x + 8)²; x≥ −8
O D. f-¹ (x) = (x+8)²; x≥0
The inverse function is [tex]f^{-1} = (x + 8)^2[/tex], and the domain is the set of all real numbers equal to or larger than -8. So the correct option is C.
How to find the inverse function?Remember that two functions are inverses if and only if:
[tex]f( f^{-1}(x)) = x\\f^{-1}(f(x)) = x[/tex]
Here we have:
[tex]f(x) = \sqrt{x} - 8[/tex]
Then we want to have:
[tex]f(f^{-1}(x)) = \sqrt{f^{-1}(x)} - 8 = x[/tex]
Solving that for the inverse function, we get:
[tex]f^{-1} = (x + 8)^2[/tex]
Now, how to get the domain. The domain of the inverse function is equal to the range of the original function.
[tex]f(x) = \sqrt{x} - 8[/tex]
The range of f(x) is the set of all real numbers larger or equal than -8 (because the smallest value that x can take is 0).
Then the domain of the inverse function is the set of all real numbers equal to or larger than -8.
The correct option is C.

A special right-angled triangle where:
Angles are in the ratio 1 : 2 : 3Sides are in the ratio 1 : √3 : 2Therefore, the formula for the sides is b : b√3 : 2b where:
b = shortest side opposite the 30° angleb√3 = side opposite the 60° angle2b = longest side (hypotenuse) is opposite the right angleThe given triangle is a 30-60-90 triangle, therefore the ratio of its sides is b : b√3 : 2b
We have been given the measure of the side opposite the 60° angle.
⇒ b√3 = 6√3
So b = 6

What is the slope-intercept equation of the line below?
Answer:
y= 2x - 3
Step-by-step explanation:
To calculate the slope (or gradient) of a line, take two points on the line whose x and y values are easy to read. Then divide the difference of they y-coordinate values by the difference of their x-coordinate values.
Here I have taken the points p (3, 3) and q (1, -1) to calculate the slope.
• slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1}}[/tex]
= [tex]\frac{3 - (-1)}{3 - 1}[/tex]
= [tex]\frac{4}{2}[/tex]
= 2
The intercept is the y-coordinate value of the point at which the line crosses ("intercepts") the y-axis. I've marked the intercept point with a green line.
• intercept = -3
The slope-intercept equation of a line takes the form:
y = mx + c
where 'm' is the slope and 'c' is the y-intercept.
Substituting the values we found into the equation gives us:
y = 2x + (-3)
∴ y = 2x - 3

Step-by-step explanation:
A constant in an expression is the number that is not attached to any variable, and this includes the sign that comes with the number.
0.05m +12
In the expression above, m is the variable thus 0.05 is known as the coefficient of m instead of a constant. Coefficients are numbers that are multiplied to variables.
+12, which can simply be written as 12, is not multiplied to any variable and is thus the constant.
The value of the number 12 will not change no matter the value of m. The fact that the value stays the same makes it a constant.

We solve an equation for a specific variable by using inverse operations to undo what is done to the variable. The resulting function is evaluated by substituting the given value for the variable.
__
a.We are given the equation ...
6x -3y = 2
Solving for y, we get ...
6x -2 = 3y . . . . . add 3y-2 to both sides
2x -2/3 = y . . . . . divide by 3
f(x) = 2x -2/3 . . . . write using functional notation

b.To find f(3), we use x=3 in the function.
f(3) = 2(3) -2/3 = 6 -2/3
f(3) = 5 1/3

If it is written as it is in the problem, then neither of the graphs is the correct option.
How to solve the compound inequality?
Here we have the inequalities:
3x ≤ 12
2x + 3 > 11
(notice that in all the options, the first inequality has a negative sign, while in the two given inequalities there are no negative sign. This means that you will never get the correct answer if you use the given information, as the problem is incorrectly written).
First, we need to isolate x on both inequalities, we will get:
3x ≤ 12
x ≤ 12/3
x ≤ 4
(As you can see, because we don't have the negative sign, this inequality is different to all the ones in the options).
And for the other:
2x + 3 > 11
2x > 11 - 3
x > 8/2
x > 4
So neither of the options is actually correct.
If we instead write the first inequality as:
3x ≤ -12
We would solve this as:
x ≤ -4
And in that case, our two inequalities are:
x ≤ -4
x > 4
