To calculate the future value we need to use the compound formula:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]where P is the principal, r is the interest rate in decimal form, n is the number of times the interest is compound in any given time t.
In this case we have that P=901, r=0.035 and since the interest is compound semiannually this means that n=2. Finally t=6. Plugging this values into the equation above we have that:
[tex]\begin{gathered} A=901(1+\frac{0.035}{2})^{2\cdot6} \\ A=1109.53 \end{gathered}[/tex]Therefore the future value would be $1109.53

After solving the inequality, we get:
[tex]x\leq -10[/tex]
With the plotted inequality given.
Step-by-step explanation:
Step 1: Manipulate and solve the inequality
The inequality is given as:
[tex]\frac{1}{2}x+8\leq 3[/tex]
Make [tex]x[/tex] the subject of the inequality to solve it:
[tex]\frac{1}{2}x+8\leq 3\\\\\text{Subtract 8 from both sides of the equation:}\\\frac{1}{2}x+8-8\leq 3-8\\\\\text{Simplify:}\\\frac{1}{2}x\leq -5\\\\\text{Multiply by 2 on both sides of the inequality:}\\2\times \frac{1}{2}x\leq -5\times 2\\\\\text{Simplify:}\\x\leq-10[/tex]
Step 2: Plot the inequality
After solving the inequality, we get:
[tex]x\leq -10[/tex]
Which means that [tex]x[/tex] consists of all values that are equal to and less than [tex]-10[/tex].
On a number line, when the inequality includes the value, it is denoted by a closed circle.

Using proportions, it is found that:
a) The graph for the distance-time journey is given at the end of the answer.
b) The average speed for the whole journey was of 25 miles per hour.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using basic arithmetic operations such as multiplication or division from the rates of the variables.
Proportions are applied to find the relation between velocity, distance and time, as velocity is distance divided by time, that is:
v = d/t.
Then, applying cross multiplication, the distance is given by:
d = vt.
On the first interval of his trip, for the first 15 minutes = 1/4 of an hour, he traveled at a velocity of 40 mph, hence the distance is:
d = 40 x 1/4 = 10 miles.
During the second interval, of 25 minutes, from 15 minutes to 40 minutes, he stopped, hence his distance remained constant at 10 miles.
During the third interval, of 20 minutes = 1/3 of an hour, Tim completed the journey at a velocity of 45 mph, hence the complete distance is given by:
d = 10 + 45 x 1/3 = 10 + 15 = 25 miles.
The graph with these three intervals is given at the end of the answer.
He drove a distance of 25 miles in one hour, hence his average speed is given as follows:
v = d/t = 25/1 = 25 miles per hour.

er 10 ft long rests against a vertical wall. if the bottom of the ladder slides away from the wall at a rate of 0.5 ft/s, how fast is the angle between the ladder and the ground changing when the bottom of the ladder is 8 ft from the wall?
The angle between the ladder and the ground changes when the bottom of the ladder is 8 ft from the wall is -1/12 radians per second.
Denoting the distance in feet between the wall and the base of the ladder by x and the angle in radians between the ladder and the ground by y, it is noted;
cos(y) = x/10
which implies;
y = arccos(x/10)
Denoting time in seconds by t, it is further noted that;
[tex]\frac{dx}{dy} = \frac{dy}{dx} \frac{dx}{dt}[/tex] (chain rule)
Noting (using a standard table of derivatives for convenience)
[tex]\frac{dy}{dx}= -\frac{1}{\sqrt{1-(0.1x)^2} }(0.1)[/tex] (also by chain rule)
The above equation changes as;
[tex]\frac{dy}{dx}= -\frac{0.1}{\sqrt{1-0.1x^2} }[/tex]
It is noted from the question that in this particular system;
[tex]\frac{dx}{dt} = 0.5[/tex] feet per second
So (denoting the derivative as a function of x)
[tex]\frac{dy}{dt}(x)=\frac{dy}{dx} \frac{dx}{dt} = - \frac{0.05}{\sqrt{1-0.01x^2} }[/tex]
At last;
[tex]\frac{dy}{dt}(8)=\frac{dy}{dx} \frac{dx}{dt} = - \frac{0.05}{\sqrt{1-0.01(64)} }[/tex]
= [tex]\frac{0.05}{\sqrt{1-0.64} }[/tex]
= [tex]\frac{-0.05}{\sqrt{0.36} }[/tex]
= -5/60
= -1/12 radians per second
The angle between the ladder and the ground changes when the bottom of the ladder is 8 ft from the wall is -1/12 radians per second.

write an equation for the line parallel to y 3x - 8 through the point (-2,-7)
Answer:
y = 3x - 1
Step-by-step explanation:
In order for lines to be parallel, they must have the same slope.
The slope of y = 3x - 8 is 3.
Now, we can solve it using point-slope form. Remember that m = 3, x₁ = -2 and y₁ = -7:
y − y₁ = m(x − x₁)
y - (-7) = 3(x - (-2))
y + 7 = 3(x + 2)
Distribute 3 and isolate y:
y + 7 = 3x + 6
y = 3x - 1
Georgina has a total of $5000 invested in a savings account that receives 0.6% APY and a CD that receives 0.9% APY. How much does she have invested in each account if her total annual interest earned is $37.50?
The amount that Georgina has invested in savings account and CD are $ 2500 each.
Given that:-
Total amount invested in savings account and CD = $ 5000.
APY in savings account = 0.6 %
APY in CD = 0.9 %
Total interest earned = $ 37.5
Let the amount invested in savings account be x.
Hence, according to the data given in the question, we can write,
Amount invested in CD = 5000 - x
Interest in savings account in a year = x*(0.6)*1/100 = 0.006x
Interest in CD in a year = (5000-x)*(0.9)*1/100 = (0.009)(5000-x) = 45 - 0.009x
Hence,
0.006x + 45 - 0.009x = 37.5
45 - 37.5 = 0.009x-0.006x
7.5 = 0.003x
x = 7.5/(0.003)
x = 7500/3 = 2500
Hence, Georgina has invested $2500 in each savings account and CD.

A material’s density is a measure of its mass per unit volume. In other words, D = M
V
. Use
this relationship to calculate the density of a shiny metal object whose mass was 200 g,
and whose volume was measured to equal 10.4 mL. Round answer to 1 d.p.
The density of the material of mass 200 g and volume 10.4 ml is 19.2 g/ml.
According to the question,
We have the following information:
Density is defined as the mass per unit volume.
So, we have the formula of density:
Density = Mass/volume
Mass of the metal object = 200 g
Volume of the metal object = 10.4 ml
Density = 200/10.4 g/ml
Density = 19.231 g/ml
Now, we will round it off to nearest 1 decimal point.
We know that when the digit is greater than 5 then the number is increased by 1 and when the digit is less than 5 then the number remains same.
So, we have:
Density = 19.2 g/ml
Hence, the density of the metal object is 19.2 g/ml.

What is permutations and combination?A set's subsets can be created in two ways: combination and permutation. When the subset's components are combined, they can be listed in any order.The subset's components are listed in a permutation in a specific order. Permutations include the arrangement of people, digits, numbers, alphabets, letters, and colors. Choosing the menu, cuisine, clothes, subjects, and team are all examples of combinations.When creating permutations, we use the notation nPr, where n represents the number of available options, P represents the permutation, and r represents the number of options you are selecting.To calculate the permutation, use the formula nPr = n! / (n - r)!Therefore,
1.75C + 2.50A = 1357.50
C + A = 606
C = 606-A
1.75(606 - A) + 2.50A = 1357.5
1060.5 - 1.75A + 2.50A = 1357.5
1060.5 + 0.75 A = 1357.5
0.75 A = 297
A = 297/0.75
A = 396
No of adults = 396

The area of the square is 21.4 cm² truncated to 1 decimal place. Write the error interval for the area, a, of the shaded region in the form m < a < n
The error interval for the area will be expressed as 64.2< a < 63.93
Error intervals may be defined as the limits of accuracy when a number has been rounded or truncated. They are the range of possible values that a number could have been before it was rounded or truncated. According to the question, Area of circle = 78.1 cm² and Area of square = 21.4 cm². If we round the area to one decimal point, we get the Area of circle = 78.1 + 0.05 and = 78.1 - 0.05 that is 78.15 and 78.05. Also, the Area of square = 21.4 - 0.05 and = 21.4 + 0.05 we get 21.35 and 21.45. Now, Area of shaded region in the form m < a < n. So, n = 78.15 - 21.35

A multi step equation with an answer of -8 can be expressed as: 2x + 20 = 4.
x = -8 when solved.
What is a Multi Step Equation?A multi step equation can be an equation that has variables or/and terms on both sides, of which we can solve for the variable in the equation by isolating the variable to one side of the equation using inverse operations.
For example, a multi step equation can be expressed as 2x + 20 = 4.
Solve for x in the equation:
2x + 20 - 20 = 4 - 20 [subtraction property of equality]
2x = -16
2x/2 = -16/2 [division property of equality]
