The description and measure of the segments and angles of the triangular-shaped photo frame, found using the triangle inequality theorem are;
Shortest side → ABLongest side → BCSmallest angle → ∠CLargest angle → ∠AWhat is the triangle inequality theorem?According to a triangle inequality theorem, the measure of the lengths of sides opposite angles of different measure, are also different and the the longest side of a triangle is opposite the largest angle of the triangle.
The interior angles of the photo frame are;'
∠B = 58°, ∠A = 82°
The angle sum property of a triangle indicates that we get the angle ∠C as follows;
∠C = 180° - 58° - 82° = 40°The triangle inequality theorem indicates that the measure of the angles opposite sides that have different lengths are also different, such that the larger angle is opposite the larger side.
According to the triangle inequality theorem, we get;
The shortest side is opposite the smallest angle, which is the angle ∠C = 40°
The side opposite ∠C is AB, therefore, the shortest side is AB
The longest side is opposite the largest angle, which is angle ∠A = 82°.
The side opposite the angle ∠A is BC, therefore, the longest side is BC
The smallest angle is the angle ∠C = 40°
The largest angle is the angle ∠A = 82°

A tortoise and a hare are competing in a 2000-meter race. The arrogant hare decides to let the tortoise have a 820-meter head start. When the start gun is fired the hare begins running at a constant speed of 7.5 meters per second and the tortoise begins crawling at a constant speed of 4.5 meters per second.
a. Write an expression in terms of t that represents the hare's distance from the starting line (in meters)
b. Write an expression in terms of t that represents the tortoise's distance from the starting line (in meters).
c. Write an expression in terms of t that represents the number of meters the tortoise is ahead of the hare.
Answers
a. The hare's distance from the starting line is represented by the expression 7.5t.
b. The tortoise's distance from the starting line is represented by the expression 4.5t+820.
c. The number of meters the tortoise is ahead of the hare is represented by the expression 4.5t+820-7.5t.
In the race, the hare is running at a constant speed of 7.5 meters per second, so their distance from the starting line is equal to their speed multiplied by the time it takes them to run that distance. This is represented by the expression 7.5t, where t is the time in seconds it takes the hare to run.
Similarly, the tortoise is crawling at a constant speed of 4.5 meters per second, so their distance from the starting line is equal to their speed multiplied by the time it takes them to crawl that distance, plus the 820-meter head start they were given. This is represented by the expression 4.5t+820, where t is the time in seconds it takes the tortoise to crawl.
To find the number of meters the tortoise is ahead of the hare, we subtract the hare's distance from the starting line from the tortoise's distance from the starting line, which gives us the expression 4.5t+820-7.5t.

8cm
27cm
6cm
17cm
30cm
The diagram is not drawn to scale.
Answers
Answer:
2064 cm²
Step-by-step explanation:
You want the surface area of a prism that is 30 cm between bases that are trapezoids with parallel sides 27 cm and 6 cm that are 8 cm apart, and slant sides that are 10 cm and 17 cm.
Base areaThe area of each trapezoidal base is ...
A = 1/2(b1 +b2)h
There are two identical bases, so their total area is ...
2A = (b1 +b2)h = (27 cm +6 cm)(8 cm) = 264 cm²
Lateral area
The lateral area of the prism is the area of the four rectangular faces. Each is 30 cm wide, and their total length is the perimeter of the base;
P = 27 cm +10 cm +6 cm +17 cm = 60 cm
lateral area = Ph = (60 cm)(30 cm) = 1800 cm²
Total surface area
The total surface area of the prism is the sum of the base area and the lateral area:
total area = base area + lateral area
total area = 264 cm² +1800 cm² = 2064 cm²
The surface area of the solid prism is 2064 cm².

Answers
One factor of the function f(x) = x3 − 6x2 + 11x − 6 is (x − 3). the x-intercepts and the y-intercept of the graph of f(x) are
x = 2, x = 3, and x = 4.(0, -6), (2, 0), (3, 0), and (4, 0). RespectivelyWhat are the x-intercepts?Generally, To find the x-intercepts, we set y equal to 0 and solve for x. In this case, the equation we need to solve is:
f(x) = x^3 - 6x^2 + 11x - 6 = 0
To solve this equation, we can use the fact that (x - 3) is a factor of the function. This means that we can write the function as:
f(x) = (x - 3)(x^2 - 3x + 2)
If (x - 3) is a factor, then x - 3 must equal 0. This gives us one x-intercept at x = 3.
To find the other x-intercepts, we can set the quadratic factor (x^2 - 3x + 2) equal to 0 and solve for x. This gives us the following equation:
x^2 - 3x + 2 = 0
We can use the quadratic formula to solve this equation:
x = (3 +/- √(9 - 8)) / 2 = (3 +/- √(1)) / 2 = (3 +/- 1) / 2
This gives us two more x-intercepts at x = 2 and x = 4.
So the x-intercepts of the graph of f(x) are x = 2, x = 3, and x = 4.
To find the y-intercept, we set x equal to 0 and solve for y. In this case, the equation we need to solve is:
f(0) = 0^3 - 6(0)^2 + 11(0) - 6 = -6
This gives us a y-intercept at (0, -6).
So the y-intercept of the graph of f(x) is (0, -6).
All of the intercepts of the graph of f(x) are, therefore (0, -6), (2, 0), (3, 0), and (4, 0).

A student receives a subsidized student loan for $10,000 with a 10-year repayment term and interest compounded monthly. Six months after she graduates from college, she will have to begin making payments. Find her monthly payment and total interest paid if the interest rate is 5.5%.
Answers
If the interest rate is 5%, the monthly payment and total interest would be $2.439.
Define interest.Interest is the sum of money that must be repaid on a loan or received in exchange for a loan. Principal refers to the borrowed or lent funds. The Amount is the total of the principal plus interest. The term "rate of interest" refers to the rate at which interest is applied to the principal.
Given,
A student receives a subsidized student loan for $10,000 with a 10-year repayment term and interest compounded monthly. Six months after she graduates from college, she will have to begin making payments.
A $10,000 subsidized student loan
Ten-year term of repayment
5.5% interest rate
First, we must determine the loan's future value (FV) over the next six months using the formula below:
FV in 6 months
= Loan Amount× (1 + Interest Rate)⁶ ($10,000×(1 + 0.055) ×6
= $2.7680.
Second, the formula for determining future value is used to determine the monthly payment:
M = FV in 6 months / (((((r)n) - 1) / r).......... (1)
When you enter all the pertinent values into equation (1), you get:
M = $2.7680 / ((((1 + 0.00466666666666667)^144) – 1) / 0.00466666666666667)
M = $2.439

Answers
The largest possible value of 2 that satisfies the equation is approximately 1.1.
What is Exponential Form Equation?
Since y=bx, y = b x is a one-to-one inverse of the exponential function, x=by x = b y, it too is a function. We simply swap x and y and solve for y to discover the inverse function, as is the case with all inverse functions.
To solve for m in the equation -2 * log(m) - 24 = -20, we can start by converting the equation into exponential form. To do this, we can raise both sides of the equation to the power of e:
[tex]e^(-2 * log(m) - 24) = e^(-20)[/tex]
Then we can simplify:
[tex]m^(-2) = e^(-20)[/tex]
Then we can solve for m:
[tex]m = sqrt[e^20]\\\\= sqrt[20*e^9]\\\\= sqrt[20] * sqrt[e^9]\\\\= 2 * 3^(1/2)= 2 * 1.732\\\\= 3.464[/tex]
So m is approximately equal to 3.464
To find the largest value of 2 that satisfies the equation [tex]log(2^2) - log(2 + 1) = 9[/tex], we can start by expanding the left-hand side of the equation:
[tex]log(2^2) - log(2 + 1) \\\\=log(2^2 / (2 + 1))\\\\ = log(4/3) = 9[/tex]
Then we can rewrite the equation as:
log(4/3) = 9
Then we can solve for 2:
[tex]2 = (4/3)^(1/9)\\\\= (4^(1/9)) / 3^(1/9)\\\\= 1.5874010519681994 / 1.4422495703074083\\\\= 1.1[/tex]

The distance between the line segments PQ, RS and TV are √53 respectively
Distance Between Two PointsThe distance between any two points is the length of the line segment joining the points. There is only one line passing through two points. So, the distance between two points can be calculated by finding the length of this line segment connecting the two points.
The formula is given as;
d = √(x₂ - x₁)² + (y₂ - y₁)²
In the first line segment;
P = (0,4), Q = (7, 2)
d = √((7-0)² + (2 - 4)²)
d = √53
b)
R = (-7, 6), S = (-5, -1)
d = √((-1 - 6)² + (-5 --7)²)
d = √53
c)
T = (0, -8), V = (2, -1)
d = √((-1 --8)² + (2 - 0)²)
d = √53
The distance between the lines are all √53 units

The linear function is y = x + 7 and it has it domain and range at (-∞, ∞) respectively while it x and y - intercepts are (-7, 0) and (0, 7) respectively.
Linear FunctionA linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
The linear function always model the form of y = mx + c
m = slopec = y-interceptTaking the points, we can find the slope of the line
m = y₂ - y₁ / x₂ - x₁
m = 8 - 0 / 1 - (-7)
m = 8 / 8
m = 1
The slope of the line is 1
Using the slope to find the y - intercept;
y = mx + c
8 = 1(1) + c
8 = 1 + c
c = 8 - 1
c = 7
The linear function is y = x + 7
The range of this function is (-∞, ∞) and the domain of the function is
(-∞, ∞).
The x and y -intercept of the function are
x - intercept = (-7, 0)
y - intercept = (0, 7)
