The square of the length of the hypotenuse of the triangle is?
The sum of squares of the lengths of the triangle is 130 and the square of the length of the hypotenuse is 65
What is a right-angled triangle?This is a triangle with 3 sides and one side is called the hypotenuse which faces one of the angles 90°
Analysis:
distance between two points = [tex]\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2} }[/tex]
distance AB with coordinates A(-2,4) B(5,0) = [tex]\sqrt{(5 - -2)^{2} + (0 - 4)^{2} }[/tex] = [tex]\sqrt{65}[/tex]

Given g(x)=^3√x+6, on what interval is the function negative?
A (-∞, -6)
B (-∞, 6)
C (-6, ∞)
D (6, ∞)
The interval which the function is negative is (-∞, -6)
How to determine the interval?The equation of the function is given as:
[tex]g(x) = \sqrt[3]{x + 6}[/tex]
When the function is negative.
It means that g(x) is less than 0
i.e. g(x) < 0
So, we have:
[tex]\sqrt[3]{x + 6} < 0[/tex]
Take the cube of both sides
x + 6 < 0
Subtract 6 from both sides
x < -6
The above represents a value from negative infinity to -6
i.e. (-∞, -6)

In January, Joanna deposited $250
into her savings account. In
February, she deposited an
additional $100. If her account has
an APR of 6% compounded monthly,
how much interest did Joanna earn
in the first two months?
The interest that Joanna earned in the first two months is $4.26.
What is the interest earned?Interest earned in the first month = future value - amount deposited.
Future value = amount deposited x (1 + monthly interest)
Monthly interest = 6/12 - 0.5% = $252.50
Interest = $252.50 = 250 = $2.50
Interest earned in the second monthly = future value of the first month + amount deposited x (1.005)
(252.50 + 100) x 1.005 = 354.26
Interest = 354.26 = 352.50 = $1.76

Two sides of an acute triangle meaure 5 inches and 8 inches. The length of the longest side is unknown. What is the greatest possible whole-number length of the unknown side?
The greatest whole possible whole number length of the unknown side is 9 inches.
How to identify if a triangle is acute?Let us have:
H = biggest side of the triangle
And let we get A and B as rest of the two sides.
Then we get:
If
[tex]A^2 + B^2 < C^2[/tex]
then the triangle is acute
Two sides of an acute triangle measure as 5 inches and 8 inches
The length of the longest side is unknown.
We have to find the length of the unknown side
WE know that the longest side of any triangle is a hypotenuse
For an acute triangle we know:
[tex]A^2 + B^2 < C^2[/tex]
Here in this sum,
a = 5 inches
b = 8 inches
c = ?
Substituting we get,
[tex]A^2 + B^2 < C^2\\\\5^2 + 8^2 < C^2\\\\25 + 64= C^2[/tex]

Answer:
[tex]\huge\boxed{\bf\:2\sqrt{5} \:\: units }[/tex]
Step-by-step explanation:
We have a figure given in the shape of a square with a diagonal (x) passing from one edge to another. We need to find the measure of its diagonal if the side of the square is [tex]\sqrt{10}[/tex] units.
We know that, a square has all equal sides. Then, all the sides of the square will be equal to [tex]\sqrt{10}[/tex] units.
Now, let's find the diagonal.
To find the diagonal of a sqaure from one of its sides, we need to know the formula ⟶ Diagonal = side [tex]\bf\:\sqrt{2}[/tex].
By using this formula,
[tex]Diagonal (x)\\= side *\sqrt{2} \\= \sqrt{10} *\sqrt{2}\\ = \sqrt{5*2*2} \\= \boxed{\bf\:2\sqrt{5} \:units}[/tex]
→ The diagonal of the square = 2√5 units.

Write a power function representing the verbal statement. (Let k represent the constant of proportionality)
A quantity W is inversely proportional to the square root of a quantity n.
W(n)=
Answer:
W = k·n^(-1/2)
Step-by-step explanation:
When two quantities are proportional, their relationship can be described by the linear equation y = kx, where k is the constant of proportionality.
Saying two quantities are inversely proportional is the same as saying one is proportional to the inverse of the other. Then "inversely proportional to the square root" is the same as "proportional to the inverse of the square root."
__
W is inversely proportional to the square root of n, so we have ...
[tex]W=k\cdot\dfrac{1}{\sqrt{n}} = \dfrac{k}{n^{\frac{1}{2}}}\\\\\boxed{W=kn^{-\frac{1}{2}}}[/tex]
_____
Additional comment
The rules of exponents let us write the square root as a fractional power, and the inverse as a negative power. Thus our power function ends up with a negative fractional power.
The Power function representing the verbal statement is W = k.[tex]n^{1/2}[/tex].
What is the Power function?A power function is in the form of f(x) = kxⁿ, where k = all real numbers and n = all real numbers. You can change the way the graph of a power function looks by changing the values of k and n.
When two quantities are proportional, their relationship can be described by the linear equation y = kx, where k is the constant of proportionality.
Now "inversely proportional to the square root" is the same as "proportional to the inverse of the square root."
According to question,
W α 1/√n
W = k/√n
W = k.[tex]n^{-1/2}[/tex]
Thus, the Power function representing the verbal statement is W = k

What is simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
To divide by a fraction, we can multiply by its reciprocal. So to simplify the expression:
((2x-3)/x ) / (7/x²)
We can multiply the numerator by the reciprocal of the denominator:
((2x-3)/x ) * (x²/7)
Simplifying this expression, we can cancel out the common factor of x in the numerator and denominator:
(2x-3) * (x/7)
Expanding the product:
(2x² - 3x) / 7
Therefore, the quotient of ((2x-3)/x ) / (7/x^2) is (2x² - 3x) / 7.

The value of (8 kg 300 g 120 mg) − (3 kg 500 g 480 mg) is; 4 kg 799 g 640 mg
How to carry out Unit Conversions?We want to find the value of;
(8 kg 300 g 120 mg) − (3 kg 500 g 480 mg)
First of all, let us convert all units to kg as;
120 mg = 0.00012 kg
300 g = 0.3 kg
Thus;
8 kg 300 g 120 mg = 8 + 0.3 + 0.00012 = 8.30012 kg
Similarly, converting the second expression;
480 mg = 0.00048 kg
500 g = 0.5 kg
Thus;
3 kg 500 g 480 mg = 3 + 0.5 + 0.00048 = 3.50048 kg
Thus, we have;

Explain the difference between using the cosine ratio to solve for a missing angle in a right
triangle versus using the secant ratio. You must use complete sentences and any evidence
needed (such as an example) to prove your point of view.
In trigonometry, secant in a right triangle, is the reciprocal of the cosine of an angle symbol: sec while cosine is in a right triangle, is the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse.
The cosine of an angle is the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse of the triangle. The cosine of ∠A will be abbreviated as cos ∠A
The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .

Step-by-step explanation:
Suppose a right triangle ABC in which
BC=3 units and AC=5 unit and angle B=90 degree
