A and b have the same direction, and they both have a magnitude of 6. What must be true about a and b ? a. They are equal and parallel.
b. They are opposites, but not parallel.
c. They are opposites and parallel.
d. They are equal, but not parallel.
Answers
Answer: Option a
They are equal and parallel
Step-by-step explanation:
If a and b have the same direction then necessarily a and b are parallel.
We know that they also have the same magnitude.
Two vectors are equal if they have the same magnitude and direction.
Then we can say that a and b are equal and we can also say that they are parallel.
Therefore the correct option is the option a

The fraction of a sandwich that each girl gets will be4/5
Number of sandwiches = 4
Number of girls = 5
Based on the question, we are given the information that they are going to share 4sandwich, therefore this will be:
= Number of sandwiches / Number of girls
= 4/5
Therefore, each of the children will only get 4/5 of a sandwich each.
In conclusion, the correct option is 4/5.

Answers
Let the base be "x"
According to the question,
h = x - 13
A = 24 in sq.
Now,
Factorizing the equation, x² - 13x -48, we get,
NOW, using zero product property, we get,
Either,
x + 3 = 0
x = -3
Or,
x - 16 = 0
x = 16
Since, distance can't be negative, we have, x = 16 in.
So, the length of the base is 16 inches.

umm...i don't know how to do it...can you post a picture of the same kind of (solved) question....i mean like an example
Answers
Answer:
5 hours 30 minutes
Step-by-step explanation:
Truck one is traveling south at 59 mph
It'd distance can be expressed as
d = 59t with d being the distance traveled, 59 is the speed, and t is
the number of hours it traveled for
Truck two is traveling north at 62 mph
It'd distance can be expressed as
d = 62t with d being the distance traveled, 62 is the speed, and t is
the number of hours it traveled for
We want their combined distance to be 665.5, so use the equation
59t + 62t = 665.5 and solve for t
121t = 665.5 (combine like terms on the left)
t = 665.5/121 (divide be 121 on both sides to isolate the
variable)
t = 5.5 (simplify)
t = 5 hours 30 minutes (0.5 hours is 30 minutes)
Final answer:
Two trucks, traveling south and north at speeds of 59mph and 62mph respectively, will be 665.5 miles apart after 5.5 hours.
Explanation:
The two trucks are moving in opposite directions, south and north, and the correct way to find the total distance between the two is by adding their speeds. So, the combined speed of the two trucks is 59 miles per hour (mph) + 62 mph = 121 mph. To find the time it will take for the trucks to be 665.5 miles apart, we need to divide the total distance by their combined speed. So, the time is 665.5 miles / 121 mph = 5.5 hours. Meaning it will take 5.5 hours for the two trucks to be 665.5 miles apart after leaving the warehouse.

Answer:
function is correct for Erin's purpose and the new growth rate is 32%
Step-by-step explanation:
Growth rate function: --A
where r is the rate of growth
We are given that The function represents the growth of a dragonfly population every year in a remote swamp.
Now Erin wants to manipulate the formula to an equivalent form that calculates four times a year, not just once a year
So, equation becomes:
Now on comparing with A
1.32=1+r
0.32=r
So, New growth rate = 0.32=32%
Hence function is correct for Erin's purpose and the new growth rate is 32%
We use the variable
z as the number of 3 months per year
So,
x = z/4
Substituting, the new growth rate would be:
f(z) = 4(3)^(z/4)
