Answer:
If it cuts x-axis 5 times.
Step-by-step explanation:
When we look at the graph of a function we can see its real roots by looking at its graph
The intersecting points that is the number of times a line cutting x-axis will be the real root of the function
So, by looking at the 5th degree function the number of time that function cuts x-axis will be the number of real roots.
So, if we need to say all the zeroes or roots of the function are real means it will cut the x-axis 5 times.
Because a function will have the root equal to its degree.
Hey there!!
In order to solve this question, we take the area as 196 as these are the total number of plants to cover a specific place.
The formation must be in a square formation
area of a square = ( s ) ²
s = side
or the number of plants in a row
s² = 196
s = √196
s = 14
There are 14 plants in each row
Hope my answer helps!
This is
{HH, TT, TH, HT} where H = head and T = tail
Answer:
Part A:
x + y = 80
x + 20 = y
Part B:
Pam spends 30 minutes practicing math every day.
Part C:
It is not possible for Pam to have spent 60 minutes practicing dance because this means she must have practiced math for 40 minutes (60 - 20 = 40). This would total out to 100 minutes of total practice, not 80 minutes. Therefore, this is impossible.
Step-by-step explanation:
Part A:
"She spends 80 minutes every day practicing dance and math."
x + y = 80
"She dances for 20 minutes longer than she works on math."
x + 20 = y
Part B:
Solve for x:
x + 20 = y
Isolate variable x:
x = y - 20
Plug in this new value for the first equation:
y - 20 + y = 80
Combine like terms:
2y - 20 = 80
Isolate variable y:
2y = 100
y = 50
Plug in the new value of y into any equation:
x + 50 = 80
Isolate variable x:
x = 30
Part C:
x + 20 = y
x + 20 = 60
x = 40
x + y = 80
40 + 60 = 80
100 = 80
Impossible.
1 - First we can determine the area of the yard alone by doing:
22 feet x 44 feet = 968 feet squared
2 - Then, we can calculate the area of the walk by first subtracting two from the original values given ( 22 and 44 ), and then subtract the area of the yard with the value given in the equation we setup and solved below:
(22-2) x (44-2) = 20 x 42 = 840 feet squared
3 - Stated in step 2, subtract 840 from the yard's area ( 968 feet squared ) to determine the space that is left over, that'll represent the 'walk' in this case:
968 - 840 = 128 feet squared
4 - Final Answer:
The area of the walk is 128 feet squared.
