CAN SOMEONE HELP ME WITH THIS PROBLEM

Mathematics
1 answer:
mestny [16]3 years ago

Hi, I believe the answer is Donna makes 0.2 revolutions per foot of distance traveled and the slope of the graph is 1/5.

To find the number of revolutions per minute you find a point on the graph where the <em>x</em> line and the <em>y</em> line match up, such as (2, 10) then you divide the amount of revolutions in ten feet by ten to find the amount in just one foot, 0.2.

To find the slope of the graph you pick two points on it such as (2, 10) and (4, 20) and subtract the first y coordinate from the second (4 - 2) and do the same with the x coordinates (20 - 10). Then you divide the difference in the y coordinates by the difference in the x coordinates to get the 2/10, then simplify to get 1/5.

Hope this is helpful and not too drawn out :)

Is 3/2 greater than 1? Or Less than
Simora [160]

Answer:

3/2 is greater than 1

Step-by-step explanation:

A little trick to immediately know if a number is more or less than when it involves fractions versus whole numbers is that improper fractions will always be greater than 1.

If you want to confirm this, dividing 3/2 equals 1.5, ergo 1.5 > 1.

In essence, improper fractions will always represent a number greater than one contrasted to proper fractions because if you put it on a perspective (let's say you have 13 pie slices but you only needed 12, that means there is a pie slice that's extra that makes it greater than the original pie slices).

Hope that helps :)

Jacques needs to convert the function f(x) = x2 − 6x + 14 to vertex form, f(x) = (x − h)2 + k, in order to find the minimum.
Anarel [89]

k = 5

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

To obtain this form use the method of completing the square

Since the coefficient of the x² term is 1 then

add/ subtract (half the coefficient of the x-term )² to x² - 6x

f(x) = x² + 2(- 3)x + 9 - 9 + 14 = (x - 3)² + 5 → k = 5

Write an equation for each description. solve for x
kipiarov [429]

Answer:

x = 33

Step-by-step explanation:

Because of the little square we know the total angle is 90

24 + 2x = 90

-24

2x = 66

/2

x = 33
