<span>d) (6-a) divide (a+5) </span>
Answer:
Surface area means all 6 sides
TOP side= 2 multiplied by 5
Bottom = 2 multiplied by 5
Right face = 2 multiplied by 8.1
Left face = 2 multiplied by 8.1
Back side = 5 multiplied by 8.1
front side = 5 multiplied by 8.1
10+10+16.2+16.2+40.5+40.5 = 133.4 cm ^2
Answer:
The answer to your question is:
a) f(a) -2 = a² - 3
b) f(a - 2) = a² - 4a + 3
c) f(b + d) = b² + 2bd + d² - 1
Step-by-step explanation:
a. f(a) - 2 = (a)² - 1 - 2
f(a) -2 = a² - 3
b. f(a - 2) = (a - 2)² - 1
f(a - 2) = a² - 4a + 4 - 1
f(a - 2) = a² - 4a + 3
c. f(b + d) = (b + d)² - 1
f(b + d) = b² + 2bd + d² - 1
Answer:
It appears to fly faster than its actual speed.
Step-by-step explanation:
In general, if talking about velocities, the direction of the movement should also be taken into account. For example, if two objects move in opposite directions, a person inside one object observes that the other one moving in the opposite goes faster than its actual speed (because the velocities are summed up). If they are moving in the same direction the opposite phenomenon is true (the velocities are subtracted).
Finally, in this example the planes move in opposite direction, therefore, a plane flying in the opposite direction will appear to fly faster.
Answer:
25.5
Step-by-step explanation:
First, make 2 5/6 into an improper fraction:
17/6
Then divide it by 4 to get the unit rate of spoons of chocolate syrup per 1/6 gallon:
17/6 / 4= 4 1/4 or 4.25 <------ Unit rate
Then multiply it by 6:
4.25*6= 25.5
Hope this helps!
