Answer:
3[tex]x^{2}[/tex] -2x - 6
Step-by-step explanation:
Subtract the 2 functions so 3[tex]x^{2}[/tex] - 2 - (2x + 4) so you get
3[tex]x^{2}[/tex] - 2 -2x - 4 so add like terms you get 3[tex]x^{2}[/tex] -2x - 6
A dog walked 25 miles in 12.5 hours. Find the speed of the dog.
Answer:
Step-by-step explanation:
Someone calculated his or her average speed to 18.36 Miles per hour (mph) Calculate your average speed This calculation will help you calculate your average speed when you have covered a certain distance over a certain time.
Answer:
2 mph
Step-by-step explanation:
if we divide our miles by our time with the equation d for distance and t for time we'll get this
d/t = s (s to represent the speed
now time to plug in our equation
25/12.5 = 2
we now have our answer of 2 miles per hour

Step-by-step explanation:
Josh and Greg leave from the same place
and travel the same route. Josh travels 2
hours and stops. Greg travels 5 hours at
double Josh's rate. After five hours, they
are 256 miles apart. Find the rate and
distance of each.
9514 1404 393
Answer:
Josh: 32 mph, 64 miGreg: 64 mph, 320 miStep-by-step explanation:
Let x represent Josh's rate of travel in miles per hour. After 2 hours, his distance is ...
distance = speed · time
distance = x · 2 = 2x
Then 2x is Greg's rate of travel After 5 hours, his distance is ...
distance = speed · time
distance = (2x) · 5 = 10x
The distance they are apart is ...
10x -2x = 256
8x = 256
x = 32
__
Josh's rate: 32 miles per hour; Josh's distance = (2 h)(32 mi/h) = 64 miles.
Greg's rate: (32 mi/h)·2 = 64 mi/h; Greg's distance = (5 h)(64 mi/h) = 320 miles.
__
Check: 320 miles - 64 miles = 256 miles . . . . correct separation

Two solids are described in the list below.
• One solid is a sphere and has a radius of 6 inches.
• The other solid is a cylinder with a radius of 6 inches and a height of 6 inches. What is the difference between the volumes, in cubic inches, of the solids in terms of pi?
A) 72pi
B) 144pi
C) 216pi
D) 288pi
Answer:216X
Step-by-step explanation:
Volume of the sphere = 4/3 πr³
radius r = 6 inches
Volume = 4/3 π(6)³
⇒ 4/3(216)π
⇒ 472π
⇒ 288π cubic inches
Volume of a cylinder = π r²h
radius r = 6 inches
height h = 6 inches
Volume = π(6)²(6)
⇒ 6³π
⇒ 216π cubic inches
Difference between the volumes = 288π - 216π = 72π

Step-by-step explanation:
A submarine 58 feet below see level. An a airplane is 264 feet above sea level. How far above is the submarine in the plane?
Answer:
322
Step-by-step explanation:
58+264=322
Answer:
322 feet
Step-by-step explanation:
if the question was two positive heights, you would subtract, and you still do. we find how many inches my father is taller than me by subtracting my height from his, and the same applies to this, though the submarine, being below sea level is at a negative height. when you subtract a negative, it's the same as adding a positive.
264 - (-58)
264 + 58 = 322

Rational Functions
Create a Model to represent the scenario.
Shrek, Donkey, and Fiona are riding in a carriage to Far Far Away. The horses, Prescott and Thaddeus, are pulling the carriage all the way. Prescott alone could pull the carriage all the way to Far Far Away and back to The Swamp in 21 days, but together they are able to pull the carriage to Far Far Away in 9 days.
Answer:
Step-by-step explanation:
Remark
I suppose the question is what is Thaddeus' time to make the trip. This is a fairly common question but not everyone knows how to solve it.
Derivation of the Formula
Prescott + Thaddeus = 1 trip
So the logic of the equation is this.
distance = 1 trip
time = number of dates
rate = ?
rate = distance / time
To find out what the contribution of Thaddeus is set up a distance time formula.
1/21 days is the rate for Prescott
1/x days is the rate for Thaddeus
Together the rate is 1/9
Solution
1/21 + 1/x = 1/9
Subtract 1/21 from both sides
1/x = 1/9 - 1/21
It's not obvious what the LCM is.
9 = 3 * 3
21 = 3 * 7
LCM: 7 * 3 *3 = 63
1/x = 7/63 - 3/63 = 4/63
1/x = 4/63 Cross Multiply
4x = 63 Divide by 4
x = 63/4
Answer
x = 15 3/4
x = 15.75

Answer:
A
Step-by-step explanation:
Angle P is intercepted by two arcs.
SB and RQ.
We can use this theorem,
If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.
So in other words,
[tex] \frac{80 + 150}{2} = rpq[/tex]
[tex]rpq = 115[/tex]
