Slope and rate of change are the same so I’m going to use the slope formula. The slope formula is y1-y2/x1-x2 so 15-3/1-(-2) which is 12/3 which means the rate of change is 4

He park trail is 10x^2+4x+2 miles long. The hiker has traveled 5x-1 miles. How much farther does the hiker need to travel to get

erma4kov [3.2K]

Answer:

$10x^2-x+3$ miles.

Step-by-step explanation:

It is given that,

Total length of park trail = $10x^2+4x+2$ miles

Total length traveled by hiker = $5x-1$ miles

We need to find the length of trail hiker need to travel to get to the end of the trail.

Required length $=10x^2+4x+2-(5x-1)$

$=10x^2+4x+2-5x+1$

$=10x^2+(4x-5x)+(2+1)$

$=10x^2-x+3$

Therefore, hiker need to travel $10x^2-x+3$ miles to get to the end of the trail.

rosa wants to use $20 to buy games. The inequality 2.50k+5.50≤20.00 represent the number of games, k, she can buy with her money

vichka [17]

Answer:

The greatest number of games Rosa can buy is 5

Step-by-step explanation:

Let

k ----> the number of games, k, that Rosa can buy with her money

we have

$2.50k+5.50\leq 20.00$

solve for k

subtract 5.50 both sides

$2.50k\leq 20.00-5.50$

$2.50k\leq 14.50$

divide by 2.50 both sides

$k\leq 5.8\ games$

therefore

The greatest number of games Rosa can buy is 5

The set of ————— consists of counting numbers, their opposites, and zero.

Nookie1986 [14]

Answer:

Integers

Step-by-step explanation:

Counting Numbers are {1,2,3,4,5,...}

Its opposite would be -1,-2,-3,-4,-5,... respectively.

It includes 0 so the whole set would be

{ ..., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, ... }

which is set of integers.

Use the Shell Method to find the volume of the solid obtained by rotating region under the graph of f(x)=x^2+2 for 0≤x≤5 about x

Irina18 [472]

For each x in the interval 0 ≤ x ≤ 5, the shell at that point has

• radius = 5 - x, which is the distance from x to x = 5

• height = x ² + 2

• thickness = dx

and hence contributes a volume of 2π (5 - x) (x ² + 2) dx.

Taking infinitely many of these shells and summing their volumes (i.e. integrating) gives the volume of the region:

$\displaystyle 2\pi \int_0^5 (5-x)(x^2+2)\,\mathrm dx=2\pi\int_0^5 (10-2x+5x^2-x^3)\,\mathrm dx=\boxed{\frac{925\pi}6}$
