Answers
The amount of the lump sum that the insurance company must put into a bank account is $6,928,571.43 option (B) is correct.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
Gertrude has a life insurance policy that will pay her family $97,000 per year.
If interest rates are at 1.4% when the insurance company has to pay
r = 1.4%
or
r = 0.014
The amount of the lump sum that the insurance company must put into a bank account:
= 97,000/0.014
= 6928571.429 ≈ $6,928,571.43
Thus, the amount of the lump sum that the insurance company must put into a bank account is $6,928,571.43 option (B) is correct.

thirteen and five sevenths cm2
fifteen and one seventh cm2
Answers
The area of the rectangle is thirteen and one seventh cm2
What is the area of the rectangle?A rectangle is a four-sided object that has two widths and two lengths. The sum of angles in a rectangle is 360 degrees.
Area of a rectangle = length x width
3 2/7 x 4
23/7 x 4 = 92 / 7 = 13 1/7 cm²
We conclude that the area of the rectangle is (13 + 1/7) cm²
How to get the area of the rectangle?
For a rectangle of length L and width W, the area is:
A = L*W
Here we know that:
L = (3 + 2/7)cm
W = 4cm
Then the area is:
A = (3 + 2/7)cm*4cm = (12 + 8/7)cm² = (13 + 1/7) cm²
We conclude that the area of the rectangle is (13 + 1/7) cm²

What is function?A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given that two lines are intersecting at point (-3, -4)
Therefore the system of equations of these two have a solution at (-3, -4)
So, if taking the lines as function,
We have f(x) and g(x),
so both of them are intersecting at (-3, -4) so the range when the domain is -3 will be equal.
Hence the correct option is f(-3) = g(-3).

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made. Different types of inequalities are represented by a variety of notations, including:
The symbol a< b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
We are given

Find the longer and shorter lengths and hypotenuses
Answers
Answer:
Short leg: 9 in
Long leg: 40 in
Hypotenuse: 41 in
Step-by-step explanation:
This problem involves the Pythagorean Theorem, solving a system of equations, and solving a quadratic equation.
The Pythagorean Theorem applies because the question states this is a right triangle. That is one equation.
Two more equations come from descriptive relationships between various sides of the triangle.
Solving the system is done here with the Substitution Method, and solving the quadratic equation is done with factoring and the zero product property. Other methods could be used, but there is a character limit, so we can't dive into every way to solve this.
The Pythagorean TheoremPythagorean Theorem: [tex]a^2+b^2=c^2[/tex] where "c" is the hypotenuse of the right triangle.
"c" must be hypotenuse.
It doesn't matter which of the two legs' lengths is used for "a" & "b". However, because of other parts of the question, we'll need to know which one is which.
The question refers back multiple times to one specific leg (the short one). So, when we refer back to that leg in our equations, we need to make sure we're using the same leg each time.
Keeping track of which leg is which
Let's use "a" for the smaller leg, and "b" for the longer leg.
"c", as always, is the hypotenuse.
Setting up the relationships between the sidesNext, the question gives two statements relating the side lengths of the triangle to each other.
For the first statement, "the length of the longer leg of a right triangle" (that's "b") "...is 13 inches more than three times the length of the shorter leg ("a").
Translating the first sentence into math:
"the length of the longer leg of a right triangle" means "b""...is..." means "=""...13 inches more than..." means " +13 " (start with what's coming next, and then do the adding)"...three times..." means " 3* ""... the length of the shorter leg." means "a".[tex]b=3a+13[/tex]
Similarly from the second statement, we get: [tex]c=3a+14[/tex]
Combining this with the Pythagorean Theorem, we have a system of 3 equations, and 3 unknowns.
[tex]b=3a+13[/tex]
[tex]c=3a+14[/tex]
[tex]a^2+b^2=c^2[/tex]
Solving a system of equationsTo solve a system of equations, there are two main methods:
The substitution methodThe elimination methodEither method can be used, but the substitution method is the most intuitive.
Substitution method
To solve a system with the substitution method, isolate variable in an equation, written in terms of the other variables, and substitute them in to try to get a single equation with a single unknown.
Looking at our system, the first two equations already have "b" and "c" isolated in terms of "a". If we substitute both of these into the third equation, we'll have a single equation in terms of a, and can attempt to solve it.
[tex]b=3a+13[/tex]
[tex]c=3a+14[/tex]
[tex]a^2+b^2=c^2[/tex]
Substituting...
[tex]a^2+(3a+13)^2=(3a+14)^2[/tex]
Rewrite the square binomials as a product...
[tex]a^2+(3a+13)(3a+13)=(3a+14)(3a+14)[/tex]
Apply FOIL (a combination of the distributive property, the commutative properties of multiplication, and combining like terms)...
[tex]a^2+(9a^2+39a+39a+169)=(9a^2+42a+42a+196)\\a^2+(9a^2+78a+169)=(9a^2+84a+196)\\[/tex]
Observe that the equation is a degree-2 polynomial (polynomial with highest power of 2; aka quadratic). Move all terms to one side to get the equation equal to zero in preparation for solving:
[tex]a^2+(9a^2+78a+169)=(9a^2+84a+196)\\a^2+9a^2+78a+169-(9a^2+84a+196)=0\\a^2-6a-27=0\\[/tex]
There are a few ways to solve this, including the quadratic formula. However, factoring the polynomial and using the zero product property is quite efficient here:
Factoring to solve a Quadratic
Since the leading coefficient is 1, we can use the shortcut and find factors of -27 that add to make -6.
-27 has factor pairs of:
1 and -273 and -99 and -327 and -13 and -9 add to make -6, so factoring the polynomial is
[tex]a^2-6a-27=0\\(a+3)(a-9)=0[/tex]
Applying the zero product property...
[tex](a+3)=0[/tex] or [tex](a-9)=0[/tex]
So a=-3 or a=9. Given that this represents a length in a triangle, we discard the negative solution. So a=9.
Finding the other two unknowns
To finish up, substitute the "a" back into the two equations for "b" and "c".
[tex]b=3a+13\\b=3(9)+13\\b=27+13\\b=40[/tex]
[tex]c=3a+14\\c=3(9)+14\\c=27+14\\c=41[/tex]
The original problem set up our measurements in inches, so all three values are measured in inches.
Remember which length was which
"a": short leg
"b": longer leg
"c": hypotenuse
Short leg: 9 in
Long leg: 40 in
Hypotenuse: 41 in.

In a softball diamond, each of the bases, including home plate, are equidistant from each other. Although the name implies differently, a softball diamond is in the shape of a square. Given that the distance between the bases is unknown, determine an expression for the straight line distance between first and third bases.
So far I know that the equation is
x² + x² = c²
But i dont know how to simplify that
Answers
The expression for the distance from the 1st base to the 3rd base in terms of side length will be c=x√2
Given that the softball diamond is square in shape.
Let the side of the square i.e. distance between consecutive bases is x
The distance from the 1st base to the 3rd base creates the hypotenuse of a right triangle, where each side is equal to x i.e. x is the side length of the square formed by the baseball diamond.
Using the Pythagorean theorem we have:
x² +x²= c²,
where c is the distance from the 1st base to the 3rd base.
Combining similar terms gives us
2x²=c²
Taking the square root of both sides we have
√2x²= √c²
⇒x√2=c
⇒c=x√2
This is the expression for the distance from the 1st base to the 3rd base in terms of side length.
Therefore the expression for the distance from the 1st base to the 3rd base in terms of side length will be c=x√2.
