Step-by-step explanation:
Area of a circle = pi r^2
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:

Which is increasing on (0, ∞).
After the translation, the function is:

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, ∞).

Answer:
a) mean=1,8 b) mean=3.6 c) mean=7.2
Step-by-step explanation:
a) 2.4 +1.6+ 3.2+ 0.3+ 1.5=9
9/5=1.8
b) 4.8+3.2+6.4+0.6+3=18
18/5=3.6
c)9.6+6.4+12.8+1.2+6=36
36/5=7.2
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.
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
