Answers
Answer:
122.46 cm²
Step-by-step explanation:
A = [tex]\pi r^{2}[/tex]
~~~~~~~~~
[tex]r_{1}[/tex] = 8 cm
[tex]r_{2}[/tex] = 5 cm
A = 3.14 ( 8² - 5² ) ≈ 122.46 cm²

The sales tax in one town is 8%. So, the total cost of an item can be written as c+0.08c. What is the total cost of an item that sells for 12?
Answers
Answer:
12.96c
Step-by-step explanation:
Given the total cost of an item written as c+0.08c. To get the total cost of an item that sells for 12, we will write;
1 item = c+0.08c
1 item = 1.08c
For 12items;
12 = x
Divide both expressions
1/12 = 1.08c/x
1 * x = 12 * 1.08c
x= 12.96c
Hence the total cost of 212 items is 12.96c

y = 7, x ≈ 9.9
Step-by-step explanation:
The remaining angle has to also be 45° which tells us we're working with an isosceles right triangle, or that y also has to be 7 (the same length).
Use the Pythagorean theorem for x.
a^2 + b^2 = x^2
7^2 + 7^2 = x^2
49 + 49 = x^2
x^2 = 98

D- Tan(55°)=c/a

Answers
Option A is the correct answer because the ratio between the opposite side and the hypotenuse side is correct.
Triangle :
A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any one angle is a right angle. Therefore, this triangle is also called the right triangle or 90-degree triangle. The right triangle plays an important role in trigonometry. Let us learn more about this triangle in this article.
A triangle with Side lengths a unit, b units, and c units.
"Opposite" is opposite to the angle θ
"Adjacent" is adjacent (next to) to the angle θ
"Hypotenuse" is the long one
A)
Sin 55 = a/c
Sin θ = opposite / hypotenuse
Option A ) is correct Sin 55 = a/c
B)
Cos(55°)=c/b
Cos θ = Adjacent / hypotenuse
Cos 55 = c/ b is not equal to the Adjacent / hypotenuse
Option B) is not a correct answer because the ratio is between Adjacent and Hypotenuse.
C)
Cos(55°)=a/b
Cos θ = Adjacent / hypotenuse
Cos 55 = a/ b is not equal to the Adjacent / hypotenuse
Option C) is not a correct answer because the ratio is between Adjacent and Hypotenuse.
D)
Tan(55°)=c/a
Tan θ = Opposite / Adjacent
Tan 55 = c/a is not equal to the Opposite / Adjacent
Option D) is not a correct answer because the ratio is between Opposite and Adjacent.

How do the asymptote and intercept of the given function compare to the asymptote and intercept of the function f(x) = 5 ^ x ? a. g(x) = 5 ^ (x + 3) b. h(x) = 5 ^ (- x)
Please help me
Answers
Answer:
Step-by-step explanation:
Asymptote is the x axis for both functions. the y intercept is translated up to 125
What is a function?A relation is a function if it has only One y-value for each x-value.
The asymptote and intercept of the given function compare to the asymptote and intercept of the function f(x) = 5ˣ
To find x- or y-intercepts, set the other variable equal to zero and solve in turn.
To find y-intercept: set x = 0 and solve for y. The point will be (0, y). To find x-intercept: set y = 0 and solve for x. The point will be (x, 0).
The asymptote is the x axis for both functions. the y intercept is translated up to 125.
Hence, asymptote is the x axis for both functions. the y intercept is translated up to 125.
