Answers
In the given triangle ABC,
i. SAS is given
ii. The law of cosine can be used to solve it.
What is the cosine rule?The cosine rule is a mathematical principle that can be applied to determine the unknown length of side, or measure of the internal angle of a none right angled triangle.
The cosine rule states that;
[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - 2abCos C
Considering the given attachment to the question, for a standard labelling of triangle ABC. It can be observed that;
a. The given properties of the triangle are: Side-Angle-Side (SAS)
b. The angle given is an included angle, so that the cosine law is required to solve the triangle.

Answers
Answer:
The correct option that compares the end behavior of the functions f and g is D.
For function f, as x → ∞, f(x) → -∞, which means that the function approaches negative infinity as x approaches infinity. This is because the leading term of the function is -17x, which approaches negative infinity as x approaches infinity.
For function g, as x → ∞, g(x) → -∞, which means that the function also approaches negative infinity as x approaches infinity. This is because the leading term of the function is -78/87x, which approaches negative infinity as x approaches infinity.
Therefore, both functions have the same end behavior, which is approaching negative infinity as x approaches infinity.

Christina Sanders is concerned about the financing of a home. She saw a small Cape Cod–style house that sells for $90,000. If she puts 10% down, what will her monthly payment be at (a) 30 years, 5%; (b) 30 years, 512% ; (c) 30 years, 6%; and (d) 15 years, 378% ? What is the total cost of interest over the cost of the loan for each assumption? (Use Table 15.1.) Note: Round your answers to the nearest cent. Do not round intermediate calculations.
Answers
The monthly payments and total cost of interest depend on the interest rate and the length of the loan. Generally, a lower interest rate or a shorter loan term results in lower total interest costs.
To calculate the monthly payments, we can use the formula for the present value of an annuity:
[tex]PV = P * (1 - (1 + r)^{-n}) / r[/tex]
where PV is the present value of the loan, P is the principal (the amount borrowed), r is the monthly interest rate, and n is the number of monthly payments.
(a) 30 years, 5%:
PV = 0.9 * $90,000 = $81,000 (since she puts 10% down)
r = 0.05 / 12 = 0.0125(monthly interest rate)
n = 30 * 12 = 360 (number of monthly payments)
Using the formula, we get:
PV = $81,000
Monthly payment = $436.82
Total cost of interest = $57,255.85
(b) 30 years, 5.12%:
r = 0.0512 / 12 = 0.00427 (monthly interest rate)
Using the formula, we get:
PV = $81,000
Monthly payment = $439.88
Total cost of interest = $59,956.19
(c) 30 years, 6%:
r = 0.06 / 12 = 0.005 (monthly interest rate)
Using the formula, we get:
PV = $81,000
Monthly payment = $485.24
Total cost of interest = $95,687.34
(d) 15 years, 3.78%:
n = 15 * 12 = 180 (number of monthly payments)
r = 0.0378 / 12 = 0.00315 (monthly interest rate)
Using the formula, we get:
PV = $81,000
Monthly payment = $591.93
Total cost of interest = $34,147.07

Answers
In this case, we have:
A = $28,000
r = 2% = 0.02
n = 365 (since interest is compounded daily)
t = 6
We want to solve for P. Substituting the given values into the formula, we get:
$28,000 = P * (1 + 0.02/365)^(365*6)
Dividing both sides by (1 + 0.02/365)^(365*6), we get:
P = $28,000 / (1 + 0.02/365)^(365*6) = $22,406.57

Answers
Note that in the line graph presented, 3/4 the distance from A to B is 12, thus, t = 12.
what is the explanation about this?
Given:
A (- 2 , 0) and B(14, 0)
Using distance formula, we can determine the distance between coordinates given:
d = √ ( (x2 - x1)² + ( y2 - y1) ²)
In this case, x1 = -2 y1 = 0,
x2 = 14, and y2 = 0.
Substituting these values into the formula, we get:
d = √( (14 - (-2 ) ) ² + (0 - 0) ²)
= √((16)² + (0)² )
= √(256)
= 16
The distanc between the points (-2,0) and (14,0) is 16 units.
Recall that we need to find the position of t which is 3/4 the distance between A and B.

72+z rewrite the expression as a produc 72
Answers
Rewriting the expression based on the information will be 72(1 + z/72).
How to explain the expressionIn order to transform 72 + z into a product based on 72, we can apply the distributive property of multiplication over addition. Essentially, this property maintains that:
a x (b + c) = a x b + a x c
By extension, we can create the following equation:
72 + z = 72 + 1 x z
In order to produce an equivalent expression as a multiple of 72 and another factor, we would then need to use the distributive rule once again:
72 + 1 x z = 72 x 1 + 72 x z/72
Simplification leads us to arrive at:
72 + z = 72(1 + z/72)
Our end result is expressed as a synthesis between 72 and the expression (1 + z/72), namely:
72(1 + z/72).

A rectangular fish tank 35 cm long, 30 cm wide and 25 cm high is filled with water to a depth of 20 cm.
Find the volume of water in the fish tank.
Give your answer in liters.
Answers
Answer:
First, we need to calculate the volume of the rectangular fish tank. The volume of a rectangular solid is given by the formula:
volume = length x width x height
Plugging in the values we have, we get:
volume = 35 cm x 30 cm x 25 cm = 26,250 cubic cm
Next, we need to find the volume of water in the fish tank. The volume of water is equal to the volume of the space the water occupies, which is a rectangular solid with length 35 cm, width 30 cm, and height 20 cm. The volume of this rectangular solid is:
volume = length x width x height = 35 cm x 30 cm x 20 cm = 21,000 cubic cm
To convert cubic centimeters (cm^3) to liters (L), we need to divide by 1000:
volume = 21,000 cm^3 ÷ 1000 = 21 L
Therefore, the volume of water in the fish tank is 21 liters.

The exact volume of the soup can is 18.375 π cubic inches. So, correct option is C.
The volume of a cylinder can be found by multiplying the area of the base (circle) by the height of the cylinder. In this case, the diameter of the base is 3.5 inches, which means the radius is 1.75 inches (since radius = diameter/2).
So the area of the base can be calculated as:
π × (1.75 in)² = π × 3.0625 in²
The height of the cylinder is given as 6 inches.
Therefore, the exact volume of the soup can would be:
π × (1.75 in)² × 6 in = π × 3.0625 in² × 6 in = 18.375 π cubic inches (rounded to two decimal places)

Which function is a translation one unit right of the function f(x) = log x?
h(x) = log x + 1
g(x) = log x-1
j(x) = log(x + 1)
k(x) = log(x - 1)
Answers
Answer:
The function that is a translation one unit right of the function f(x) = log x is k(x) = log(x - 1).
When we shift a function f(x) one unit right, we replace x with (x - a) where "a" is the amount of the shift. In this case, "a" is equal to 1. Therefore, the function becomes:
f(x - 1) = log(x - 1)
This means that the function k(x) = log(x - 1) is obtained by shifting the function f(x) one unit to the right.
