Answer:
1/555 miles
Step-by-step explanation:
The question requires that we determine the speed in miles per second. From the definition of speed, it's distance covered per unit time. In this case, the distance covered is in miles and unit time is seconds.
Distance=1/3 mile
Time= 3 minutes, 5 seconds
Speed=Distance (miles) /time(s)
Converting time to seconds, we multiply by 3 minutes by 60=3*60=180 seconds
Total time=180+5=185 seconds
Substituting distance with 1/3 mile and time with 185 seconds we get speed as
Speed=0.001801802 or 1/555 miles per second

nnnnnnnnnnnnnnmnnnnnnnnnnnnnnnnnnnnnnnnnn
Step-by-step explanation:
2.
The 21 degree angle shown is a corresponding angle to angle 3, which means they are identical, so angle 3 is 21 degrees.
Angle 3 and 4 are supplementary angles which need to add up to 180 degrees.
Angle 4 = 180 - 21 = 159 degrees.
3. A bisector means both sides are the same length.
Set the two equations to equal to solve for x:
4x+12 = 2x +18
Subtract 2x from both sides:
2x +12 = 18
Subtract 12 from both sides:
2x = 6
Divide both sides by 2:
x = 3
Now you have x, solve both equations and add them together:
4(3) +12 = 12+12 = 24
2(3) +18 = 6+18 = 24
24 +24 = 48
AB = 48
Answer:
f(x)= 3(x - 2)(x + 2)
Step-by-step explanation:
The given quadratic function f(x) = 3x^2 - 12
Let's factor the given function.
f(x) = 3x^2 - 3*4
Here the common factor is 3, we can take it as common factor and write the remaining terms.
f(x) = 3(x^2 - 4)
Now we can factor (x^2 - 4) using the formula (a^2 - b^2) = (a-b)(a + b)
(x^2 -4) = (x^2 - 2^2)
= (x - 2)(x + 2)
Therefore, f(x) = 3(x^2 - 2^2)
f(x)= 3(x - 2)(x + 2)
Hope this will help you to understand the concept.
Thank you.
