Given the function h of x equals negative 2 times the square root of x, which statement is true about h(x)?
gavmur [86]

Using translation concepts, it is found that the correct statement about h(x) is:

The function is decreasing on the interval (0, ∞).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the parent function is:

f(x) = \sqrt{x}

Which is increasing on (0, ∞).

After the translation, the function is:

h(x) = -2\sqrt{x}

It was multiplied by a negative number, which means that it was reflected over the x-axis, and it will be decreasing on the interval (0, ∞).

Write a proportion to find how many points xx a student needs to score on a test worth 50 points to get a test score of 78%.
Archy [21]
Let
 x = points that a student needs to score on a test
 p = points worth the exam.
 to find how many points to student needs to score on a test to get a test score of 78%. it will be given by
 x = 0.78 * p
 Thus, in a 50-point test, the number of points the student needs to get to get a test score of 78% will be
  x = 0.78 * 50 = 39 points.

Please help me with my math problem! It would be very much appreciated!
IrinaK [193]

Answer:

A = 1133.54 cm^2

Step-by-step explanation:

Remember, our diameter is twice the length of our radius.

Diameter = 2 * Radius

Our diameter is 38 cm, meaning our radius is 19 cm.

A = pi * (r^2)

A = 3.14 * (19cm)^2

A = 3.14 * 361cm^2

A = 1133.54 cm^2
