F(x)=x^2-(1/2)x+4
g(x)=8x-2
(g o f)(x)=?

(g o f)(x)=g(f(x))=g(x^2-(1/2)x+4)
x=x^2-(1/2)x+4→g(x^2-(1/2)x+4)=8[x^2-(1/2)x+4]-2
g(x^2-(1/2)x+4)=8x^2-4x+32-2
g(x^2-(1/2)x+4)=8x^2-4x+30

Answer: (g o f)(x)=8x^2-4x+30

For this case, the first thing we must do is the composition of functions.
 We have:
 f (x) = x ^ 2- (1 / 2x) +4
 g (x) = 8x-2
 (gOf) (x) = 8 (x ^ 2- (1 / 2x) +4) -2
 We rewrite: now the function:
 (gOf) (x) = 8x ^ 2- (8/2) x + 32-2
 (gOf) (x) = 8x ^ 2-4x + 30
 Answer:
 
The final result is:
 
(gOf) (x) = 8x ^ 2-4x + 30

Answer:

4√34

Step-by-step explanation:

Let the unknown side be y

y^2 = 20^2 + 12^2

y^2 = 400 + 144

y^2 = 544

Take the square root of both side

y = √544

y = √(16x34)

y = √16 x √34

y = 4√34

A sine function has an amplitude of 3, a period of pi, and a phase shift of pi/2. What is the y-intercept of the function?
jarptica [38.1K]

Based on the calculations, we can logically deduce that the y-intercept of this sine function is equal to: A. 3.

<u>Given the following data:</u>

  • Amplitude = 3
  • Period = π
  • Phase shift = π/2

<h3>How to determine the y-intercept of this function?</h3>

Mathematically, a sine function is modeled by this equation:

y = Asin(ωt + ø)

<u>Where:</u>

  • A represents the amplitude.
  • ω represents angular velocity.
  • t represents the period.
  • ø represents the phase shift.

Also, the period of a sine wave is given by:

t = 2π/ω

2 = 2π/ω

ω = 2

Substituting the given parameters into the equation, we have;

y = 3sin(2t + π/2)

At t = 0, we have:

y = 3sin(2(0) + π/2)

y = 3sin(π/2)

y = 3sin(90)

y = 3 × 1

y = 3.

In conclusion, we can logically deduce that the y-intercept of this sine function is equal to 3.

In spherical geometry, all points are points on the surface of a sphere. A line is a circle on the sphere whose diameter is equa
mamaluj [8]

Answer: It is not possible that two triangles that are similar and not congruent in spherical geometry.

Step-by-step explanation:

For instance, taking a circle on the sphere whose diameter is equal to the diameter of the sphere and inside is an equilateral triangle, because the sphere is perfect, if we draw a circle (longitudinal or latitudinal lines) to form a circle encompassing an equally shaped triangle at different points of the sphere will definately yield equal size.

in other words, triangles formed in a sphere must be congruent and also similar meaning having the same shape and must definately have the same size.

Therefore, it is not possible for two triangles in a sphere that are similar but not congruent.

Two triangles in sphere that are similar must be congruent.
