Answer:

all real numbers

Step-by-step explanation:

The graphs of positive and negative x^2 parabolas will always have a domain of all real numbers. Even though you only have a portion of the graph and see a "restriction" on your domain values, it is incorrect to assume that the domain is limited to what you can see. As the branches of the parabola keep going up and up and up, the values of x keep getting bigger and bigger and bigger. Again, this is true for all + or - parabolas. ....... Can consider brainlist*:)

I believe that it is All Real Numbers because it is asking for the domain of function f, which is referring to the x axis only. If you were to graph that as an inequality, you’d come to the conclusion that the line could extend to all possible numbers on the x-axis.

A ball is dropped from a height of 10 meters. Each time it bounces, it reaches 50% of its previous height. The total vertical di

yan [13]

Answer:

28.75 m.

Step-by-step explanation:

It is given that a ball is dropped from a height of 10 meters. Each time it bounces, it reaches 50% of its previous height. So,

For first bounce the vertical distance $a_1= 10\ m$

For next bounce ball has to travel up and down by 50% of previous distance, i.e., 10 m.

For second bounce the vertical distance $a_2=2\times (\dfrac{50}{100}\times 10)=2(5)=10\ m$

Similarly,

For third bounce the vertical distance $a_3=2\times (\dfrac{50}{100}\times 5)=2(2.5)=5\ m$

For fourth bounce the vertical distance $a_4=2\times (\dfrac{50}{100}\times 2.5)=2(1.25)=2.5\ m$

For fifth bounce the vertical distance $a_5=2\times (\dfrac{50}{100}\times 1.25)=2(0.625)=1.25\ m$

The total vertical distance down the ball has traveled when it hits the the 5th time is

$\text{Total distance}=a_1+a_2+a_3+a_4+a_5$

$\text{Total distance}=10+10+5+2.5+1.25$

$\text{Total distance}=28.75\ m$

Therefore, the total vertical distance down the ball has traveled when it hits the the 5th time is 28.75 m.

What percent of 137.4 is 96?

Neporo4naja [7]

X = 96

100 137.4

137.4x=(100)(96)

137.4x=9600

137.4x/137.4=9600/137.4

x=70%
