A rare baseball card that was purchased increases in value over time. The function C(t) is represented on the following graph, w

here C represents the value of the card, and t is time in years since the card was purchased.
What is the initial value, and what does it represent?

Select the statement that answers both parts of the question correctly.

The initial value is 0 and it represents the lowest value of the card.

The initial value is 10 and it represents the amount of time it takes for the card to increase in value.

The initial value is 12,000 and it represents the price of the baseball card at the time of purchase.

The initial value is 12,000 and it represents the price of the card when it was new.

The length of a side of an equilateral triangle is 40cm. what is the length of the altitude of the triangle?
podryga [215]

Answer:

20√3 cm

Step-by-step explanation:

Altitude of an equilateral triangle splits it into 2 equal right triangles, it bisects the base and the angle opposite to the base.

<u>Let the altitude be x. Then as per Pythagorean theorem:</u>

  • x² = 40² - (40/2)²
  • x²= 1600 -400
  • x²= 1200
  • x= √1200
  • x= 20√3 cm

<u>Correct choice is</u> the second one

Questions, are all in picture, please solve
Andrews [41]

The function represents a <em>cosine</em> graph with axis at y = - 1, period of 6, and amplitude of 2.5.

<h3>How to analyze sinusoidal functions</h3>

In this question we have a <em>sinusoidal</em> function, of which we are supposed to find the following variables based on given picture:

  1. Equation of the axis - Horizontal that represents the mean of the bounds of the function.
  2. Period - Horizontal distance needed between two maxima or two minima.
  3. Amplitude - Mean of the difference of the bounds of the function.
  4. Type of sinusoidal function - The function represents either a sine or a cosine if and only if trigonometric function is continuous and bounded between - 1 and 1.

Then, we have the following results:

  1. Equation of the axis: y = - 1
  2. Period: 6
  3. Amplitude: 2.5
  4. The graph may be represented by a cosine with no <em>angular</em> phase and a sine with <em>angular</em> phase, based on the following trigonometric expression:

    cos θ = sin (θ + π/2)

Solve the equation: 5x + 7= 7x +23
olga nikolaevna [1]

Answer:

x = -8

Step-by-step explanation:

1)  5x + 7= 7x +23

Move the terms

2)  5x + 7 -7x = 23

Collect like terms

3)  5x -7x = 23 - 7

Calculate

4)  -2x = 16

Divide both sides by <em>-2</em>

5)  x = -8
