If ƒ(x) = 2x² + 3, then which of the following represent ƒ(x + 1)?

1 answer:

3 0

This is a bit harder. I suggest getting the Domain and Range for the function of x.
If any of these answers have, an infinite domain and (3, infinite) range. That will be your answer.

Your answer is B.

f(x) = 2x²+3 has the same domain and range as x²+3

The 888 mile trip to the ranch took three times as long as the 280 mile trip to the ocean because the speed was 4 mph less than

ziro4ka [17]

Alright, lets get started.

Suppose the speed to the ranch = x mph

So, speed to the ocean will be = (x-4) mph (because the speed was 4 mph less than the speed to the ranch)

Distance to the ranch = 888 miles

time moving to the ranch $= \frac{distance}{speed}$

time moving to the ranch $= \frac{888}{x}$

time moving to the ocean $= \frac{280}{x-4}$

As per given in question, the 888 mile trip to the ranch took three times as long as the 280 mile trip to the ocean , means

$\frac{888}{x} = 3 * \frac{280}{x-4}$

$\frac{888}{x}= \frac{840}{x-4}$

Corss multiplying

$888 (x-4) = 840 x$

$888 x - 3552 = 840 x$

$48 x = 3552$

$x=74$

Hence speed to ranch = 74 mph

Hence speed to ocean = $74 - 4 = 70$ mph

time for trip to ranch = $\frac{888}{74} = 12$ hrs

time for trip to ocean = $\frac{280}{70} = 4$ hrs

So, speed to ranch is 74 mph and trip time is 12 hrs and speed to ocean is 70mph and time is 4 hrs.

Hope it will help :)

A snow cone is a tasty treat with flavored ice and a spherical bubble gum ball at the bottom, as shown below: Snow cone with sph

o-na [289]

To solve this problem you must apply the proccedure shown below:

1. You have the following information given in the problem above:

- The <span>spherical bubble gum ball is at the bottom
- The radius of the cone is 1.5 inches, and its height is 3 inches.
- The diameter of the bubble gum ball is 0.5 inches.

2. Therefore, you must apply the formula for calculate the volume of a sphere to find the volume of the bubble gum ball:

Vs=4</span>πr^3/3

r is the radius (r=0.5 inches/2=0.25 inches)

Vs=4π(0.25 inches)^3/3
Vs=0.065 inches^3

3. The volume of the cone is:

Vc=πr^2h/3

r is the radius of the cone (r=1.5 inches)
h is the height (h= 3 inches)

Vc=π(1.5 inches)^2(3 inches)/3
Vc=7.06 inches^3

W<span>hat is the closest approximation of the volume of the cone that can be filled with flavored ice?

Vt=Vc-Vs
Vt</span>≈7.00 inches^3
