Answer:
The zeroes are and
On the graph, each of these zeroes represent the x-value where the equation will intersect with the x-axis.
Step-by-step explanation:
We have the quadratic equation
To factor this we need to find two numbers that fulfill the following:
They add up to 1
They multiply to give you -20
These two numbers are -4 and 5
This means that the quadratic equation in its factored form will be:
Now that we have the factored form, we need to set and solve for x
From this factored form, we can see that when and the result will be zero. Just to check we can plug in each of these x values
The result of this confirms that x=4 and x=-5 are indeed the zeroes of this equation.
Each of these zeroes represent the x-value where the equation will intersect with the x-axis.
Answer:
0.16. I hope this helps!
Step-by-step explanation:
10 inches = 0.83 feet
8 inches = 0.67 feet
Area = bh
0.83 × 0.67 = 0.16
Answer:
20(E)
Step-by-step explanation:
Printing press R, S and T are working together at their respective constant rate.
They can do a job for 4 hours.
Let r, s and t be the time for printing press R, S and T to complete the job alone at their respective constant rate.
Rate of printing press R = 1/r
Rate of printing press S = 1/s
Rate of printing press T = 1/t
Rate = job / time
R + S + T = 4
1/r + 1/s + 1/t = 1/4
S + T = 5
1/s + 1/t = 1/5
Substitute 1/s + 1/t = 1/5 in the equation 1/r + 1/s + 1/t = 1/4
1/r + 1/5 = 1/4
1/r = 1/4 - 1/5
1/r = (5 - 4)/ 20
1/r = 1/20
r = 20 hours
It takes the printing press R 20 hours to complete the job alone
