Consider the graph of f shown be
Estimate the average rate of change from X = 2 to x = 5.
Answer:
Average rate of change = [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
We have to calculate the average rate of change of the graph at x = 2 to x = 5.
From the graph attached,
At x = 2,
f(2) = 3
At x = 5,
f(5) = 7
Since, average rate of change of the function between x = a and x = b is defined by,
Average rate of change = [tex]\frac{f(b) - f(a)}{b - a}[/tex]
Therefore, average rate of change of the function represented by the graph will be = [tex]\frac{7-3}{5-2}[/tex]
= [tex]\frac{4}{3}[/tex]

A cone has a volume of 3 pi and a radius of 1 what is its height
Answer:
The answer should be 2
Step-by-step explanation:
16 pi = 1/3 pi r^2 ( 12) Divide both sides by pi
16 = 1/3 r^2 (12) 1/3 * 12 = 4
16 = 4 r^2 divide both sides by 4
4 = r^2 You should be able to take it from here !
Admission to the circus costs $4 plus $0.50 per ride. Ella spent $17.50 at the circus.
Answer:
Ella went on 27 rides.
Step-by-step explanation:
$17.50 - $4 = $13.50
Prove that 17^16+17^14 is divisible by 5
We'll use the exponent rule that a^(b+c) = a^b*a^c
to break up 17^16 into 17^(14+2) = 17^14*17^2
That allows us to factor like so
17^16+17^14
17^14*17^2+17^14*1
17^14(17^2 + 1)
Computing 17^14 is a lot more difficult compared to computing 17^2 + 1, assuming you only could use paper and pencil.
Note that 17^2 = 17*17 = 289, so 17^2 + 1 = 289+1 = 290
Because 290 ends in a 0, this means that 5 is a factor
290 = 5*58
This makes 5 to be a factor of the original expression.
----------------
So overall,
17^16+17^14 = 17^14(17^2 + 1) = 17^14*290 = 17^14*5*58 = 5*17^14*58
The stuff "17^14*58" doesn't matter. All we care about is that factor of 5.
Since 5 is a factor, this means that 17^16+17^14 is a multiple of 5, or 17^16+17^14 is divisible by 5.
Phrased another way, 17^16+17^14 all divided over 5 leads to some integer. In this case, the integer would be the result of 17^14*58.

Round 0.043 to the nearest hundred
Answer:
0.04
Step-by-step explanation:
Find the number in the hundredth place, in this case its 4
and look one place to the right for the rounding digit, in this case its 3
Round up if this number is greater than or equal to 5 , and round down if it is less than 5.
Answer:
0.04
Step-by-step explanation:
I was taught "5 or more, let it soar, 4 or less, let it rest" Since the number next to the hundreths place is 3, the 4 stays the same.

Answer:
[tex]21.79 + c \leq 25[/tex]
Joshua can spend up to 3.21 on a card.
Step-by-step explanation:
[tex]21.79 + c \leq 25[/tex] is the correct equation because Joshua is spending 21.79 on flowers, a certain amount on the card, and the maximum he can spend is 25. That is why you use the less than or equal to sign.
To solve, first subtract 21.79 from both sides to get: [tex]c \leq 3.21[/tex]. This means that Joshua can spend up to 3.21 on a card.
Hope it helps!

Step-by-step explanation:
EDGE 2021
The perimeter of the parallelogram is of 44 units.
What is the perimeter of a figure?
The perimeter of a figure is given by the sum of all it's outside measures.
In this problem, since it is a parallelogram, we have that:
AD = BC
Hence:
3x - 1 = 2x + 2
x = 3
Hence:
AD = BC = 3x - 1 = 3(3) - 1 = 8
We also have that:
AB = DC
4y - 2 = 2y + 6
2y = 8
y = 4
Then:
AB = DC = 4y - 2 = 4(4) - 2 = 14
Thus, the perimeter is:
2 x (14 + 8) = 44 units.
