Answer:

The sum would be

$\frac{3}{2}$

The difference would be

$\frac{2}{3} - \frac{5}{6} = - \frac{1}{6} \\ \\ or \\ \\ \frac{5}{6} - \frac{2}{3} = \frac{1}{6}$

NEED ASAP NEED TO RURN IN FAST!!! WILL MARK *BRAINLIEST*

Travka [436]

Answer:

Step-by-step explanation:

We know that:

-measuring a cone
-diameter: 18 units
-height: 8 units

We need to know how to find the volume of this cone. To do this, we need the equation to find the volume of a cone:
$V= \pi r^2\frac{h}{3}$ where r=radius and h=height

Upon assessing this equation we also now know that we are missing a radius.

For a circle, the radius is the distance from the midpoint, center, to the border of the circle. The diameter is the distance from the border of one circle to another, passing through the midpoint. Knowing this, we can conclude that the diameter is two times the radius.

Using this information we can figure out the radius for this cone: 9 units.

Now that we have the radius, we can plug in the rest of the numbers with the correct placements.

$V= \pi 9^2\frac{8}{3}$ square the 9 by calculating 9 times 9.

$V=\pi*81*\frac{8}{3}$ combine like terms and keep pi separate.

V=216 $\pi$ cubic units
Since this problem is asking for volume, we will used cubic units.

Complete Question

Peyton is a sprinter who can run the 40-yard dash in 4.5 seconds. He converts his speed into miles per hour, as shown below.

Which ratio is incorrectly written?

40 yd/4.5 sec • 3 ft/1 yd • 5280ft/1 mile • 60 sec/1 min • 60 min/1 hr

Answer:

5280ft/1 mile is the incorrect ratio

Hence, 40-yard dash in 4.5 seconds = 18.2 miles per hour(mile/hr)

Step-by-step explanation:

We are to convert 40 yards per 45 seconds to Mile per hour.

We are given the following conversion ratios:

40 yd/4.5 sec • 3 ft/1 yd • 5280ft/1 mile • 60 sec/1 min • 60 min/1 hr

The incorrect ratio is 5280ft/1 mile .

It should have been written as 1 mile/5280 ft.

Hence,

40 yd/4.5 sec • 3 ft/1 yd • 1 mile/5280ft• 60 sec/1 min • 60 min/1 hr

= 432000mile/23700 hr

= 18.181818182 mile/hr

Approximately= 18.2mile/hr

Find a formula for the nth term in this

stepan [7]

The formula of nth term is = 10 - 3n

What is AP?

A series of numbers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms. Take the numbers 5, 7, 9, 11, 13, and 15 as an example. . . is a sequence of numbers having a common difference of two.
The n-th term of the sequence is given by:, if the beginning term of an arithmetic progression is and the common difference between succeeding members is, then
If the AP contains m phrases, then denotes the final term, which is given by:
The term "finite arithmetic progression" or "arithmetic progression" refers to a finite segment of an arithmetic progression. An arithmetic series is the total of a finite arithmetic progression.

Acc to our question-

For the nth term in an algebraic series
U(n) = a + (n - 1)d
the number of terms is n.
The first term is a.
d is the typical difference
From the preceding sequence
a = 7
d = 4 - 7 = - 3
The nth term's formula is
U(n) = 7 + (n - 1)-3
= 7 - 3n + 3
The ultimate solution is
= 10 - 3n

Hence,The formula of nth term is = 10 - 3n

Write a function to represent the set of ordered pairs.

77julia77 [94]

Answer:

Option C $f (x) = x^ 2 - 2$

Step-by-step explanation:

Note that the relation describing the set of ordered pairs does not change at a costing rate

$y_2 -y_1 = 7-2 = 5\\\\y_3 -y_2 = 14- 7 = 7\\\\y_4 - y_3 = 23- 14 = 9$

Therefore the relationship is not linear.

However, the exchange rate $y_n- y_{n-1}$ increases by a factor of 2 units when n increases 1 unit. This allows us to conclude that the relationship is quadratic

Note that the following ordered pairs belong to the function

$y = x ^ 2$

A = {(2, 4), (3, 9), (4, 16), (5, 25)}

The set of ordered pairs that we have is:

B = {(2, 2), (3, 7), (4, 16), (5, 23)}

Note that there is a similarity between both sets of ordered pairs.

In set B the values of y are always 2 units less than the values in y of the set A.

Then we deduce that since the function that models the set A is $y = x ^ 2$ then the function that contains the ordered pairs of the B set is:

$y = x ^ 2 -2$

The correct option is option C) $f (x) = x^ 2 - 2$
