In geometry,

A point represents a point

Two points define a line extended on both sides of the points.

Two points define a ray if it extends on only one side of either of the points.

Three or more than three points define a plane.

Now as far as a wall is considered, it is a flat surface on which we can plot infinite points.

Hence the wall represents a plane.

Option C) is the right answer.

What is the average rate of change in f(x) over the interval [4,13]?

mestny [16]

we know that

Average Rate of Change. is the change in the y-value divided by the change in the x-value for two distinct points on the graph

$A=\frac{(f(b)-f(a))}{(b-a)}$

in this problem

$a=4\\ b=13\\ f(a)=f(4)=8\\ f(b)=f(13)=11$

substitute the values in the formula above

$A=\frac{(11-8)}{(13-4)} \\ \\ A=\frac{3}{9}$

Divide by $3$ both numerator and denominator

$A=\frac{1}{3}$

therefore

the answer is

$\frac{1}{3}$

June and Armando are each in a hot air balloon. Armando's balloon is at a slightly higher elevation than June's. The two balloon

Mandarinka [93]

Answer:

46.63 ft

Step-by-step explanation:

I've drawn and attached a triangle diagram to represent this elevation and distance of balloons.

Now, from the diagram attached, we can see the angle at which June must look up to see Armando is 25°.

Also, the height of Armando above June is represented by "x".

Thus, using pythagoras theorem, we can find x.

Thus;

x/100 = tan 25

x = 100 × tan 25

x = 100 × 0.4663

x = 46.63 ft

Andreyy89

So 5
then 5 times 5
then 5 times 5 times 5
so it seems that for x rounds, there will be 5^x

A: 4 rounds so 5^4=625 photos
B. see how many times 5 goes into 78125. the answer is 7 so 7 rounds
C. 1 million=1,000,000 so try big numbers
5^10=9,765,625 too big
5^9=1,9,53,125 too big
5^8=390625 too small
the minimum is 5^9 or 9 rounds

A:4
B:7
C:9
