disa [49]3 years ago
3 0

Answer:

  A.  219.80 square centimeters

Step-by-step explanation:

The total surface area is given by ...

  A = πr(r+s)

where r is the radius and s is the slant height. Filling in the given numbers, you get ...

  A = 3.14·(5 cm)·(5 cm +9 cm) = 219.80 cm²

How do you find area and perimeter of a rectangle with the side lengths of 5x^2 and 12x?
valentinak56 [21]

Answer:

The area can be found by multiplying the two terms, and the perimeter by doubling and adding them.

Using this, we find that the area of the rectangle is 60x³, and the perimeter is 10x² + 24x.

Step-by-step explanation:

First let's find the area:

5x² × 12x

= 60x³

Now the perimeter:

2(5x² + 12x)

= 10x² + 24x

In the triangle XYZ the measure of angle YXZ is 50 degrees and the measure of angle XYZ is 75 degrees. What is the measure of an
lbvjy [14]
<h2>Answer: 55 degrees</h2>

Step-by-step explanation:

Every triangle has 3 sides and 3 interior angles whose measures sum to 180 degrees. For example, a triangle with angles \theta, \alpha and \beta:

\theta+\alpha+\beta=180\º

Following this rule, we will apply it to the angles XYZ, YXZ and the unknown XZY:

XYZ+YXZ+XZY=180\º

50\º+75\º+XZY=180\º

XZY=180\º-50\º-75\º

Finally:

XZY=55\º

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.
