A student inscribes a triangle inside a circle. The triangle divides the circle into arcs with the following measures: 46°, 102°, and 212°. What are the measures of the angles of the triangle?

Answers

Answer 1
Answer: The angle of each arc is going to equal the measure of the angle opposite the arc... so the angles of the triangle will also be 46 degrees, 102 degrees, and 212 degrees.

(Look at one of the angles of the triangle and follow it as it opens up all the way to the other side of the circle and you'll see the equivalent arc)

The product of 3.68 can be obtained from the following expressions:

B. 4.6 × 8      D. 4.6 × 0.8

How to determine the expressions of a product?

Let's calculate the products and see which expressions result in a product of 3.68.

B. 4.6 × 8 = 36.8

D. 4.6 × 0.8 = 3.68

They are explained below:

Option B (4.6 × 8) results in a product of 36.8, which is not equal to 3.68.

Option D (4.6 × 0.8) results in a product of 3.68, which matches the desired value.

Therefore, the expressions that have a product of 3.68 are option D: 4.6 × 0.8.

How to find the inverse of the function f(x)=2x-3 ? Please

Answers

f(x)=2x-3\n\ny=2x-3\n\n-2x=-y-3\ \ \ \ /:(-2)\n\nx=(1)/(2)y+(3)/(2)\n\nf^(-1)(x)=(1)/(2)x+(3)/(2)
f(x)=2x-3

The line that divides a parabola in half is..?

Answers

The line of symmetry that divides a parabola in half as "The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola".

What is parabola?

A parabola is an approximately U-shaped, mirror-symmetrical plane curve. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line. Three different parabolas exist. Vertex form, standard form, and intercept form are the three forms. You can access a unique key feature for the graph on each form. A parabola's general equation is written as y = a(x - h)² + k or x = a(y - k)²+ h. Vertex here is indicated by (h, k).

Adita has two options for how to invest $1,000.Plan A: Put the $1,000 in an account that pays $100 per year.
Plan B: Put the $1,000 in an account that pays 5 percent interest per year.

Which statement is true?
Plan A will be worth more than plan B after two years.
Plan A will be worth the same amount as plan B after one year.
Plan B will be worth more than plan A after three years.
Plan B will be worth more than plan A after four years.

Answers

First let's calculation
Plan A = 1000 dollars to be invested in an account that pays 100 dollars per year. (1000 + 100 = 1100 dollars in a year)
Plab B = 1000 dollars to be invested in an account that pays 5% interests per year  (1000 * .05 = 50 => 1000 + 50 = 1050 dollars per year)
Thus the correct answer is Plan A will be worth more than plan B after two years.

The true statement is Plan A will be worth more than plan B after two years.

What is the worth of the plans with the passage of time?

The equation that can be used to represent the future value of plan A:

Total value = initial value x ($100 x number of years)

Value in 2 years: 1000 x (100 x 2) = $1200

Value in 3 years: 1000 x (100 x 3) = $1300

Value in 4 years: 1000 x (100 x 4) = $1400

The equation that can be used to represent the future value of plan B:

FV = P (1 + r)^n

  • FV = Future value
  • P = Present value
  • R = interest rate
  • N = number of years

  • Value in 2 years: 1000 x(1.05^2) = $1102.50
  • Value in 3 years: 1000 x(1.05^3) = 1157.63
  • Value in 4 years: 1000 x(1.05^2) = 1215.51
