Answer:
The discriminant of the quadratic equation is 0
Step-by-step explanation:
Here, we want to calculate the discriminant of the given quadratic equation
Mathematically, we have the discriminant calculated by the following formula;
D = b^2 - 4ac
where;
b represents the coefficient of x which is -2
a is the coefficient of x^2 which is 1/7
c is the last number which is 7
Substituting these values;
D = (-2)^2 -4(1/7)(7)
D = 4 - 4
D = 0
Answer:
P =44 cm
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
121 = s^2
Taking the square root of each side
sqrt(121) = sqrt(s^2)
11 = s
We want to find the perimeter of a square
P = 4s where s is the side length
P = 4(11)
P =44 cm
To find how many times 63 goes into 3000, divide 3000 by 63.
= 3000 ÷ 63
= 47.619047619
ANSWER: 47.619047619 (round per teacher requirements; if rounding to a whole number= 48)
Hope this helps! :)
