Answer:
If that is supposed to say she sold 5 DOZEN eggs at the farmer's market then The farmer gave away 7 dozen eggs which would be 84 eggs. She earned $22.50
Step-by-step explanation:
12 dozen - 5 dozen = 7 dozen
7 dozen x 12 = 84 eggs
5 dozen x 4.50 = $22.50
$25.90 because if you move the decimal over one place in 18.50 you get 1.85 that is 10% so you take that times four and get $7.50 add that to 18.50 and you get the answer
Answer:
a) (x + 5) (x - 5)
b) (x + 5i) (x - 5i)
c) (x + (5i/2)) (x - (5i/2))
d) (x-1)(x-1)
e) x +i√3 +1) (x -i√3+1)
Step-by-step explanation:
To solve this, we will need to factorize each quadratic function making it equal to zero first and then proceeding to find x
a) f(x) = x²-25
x²-25 = 0
⇒(x + 5) (x - 5)
b) f(x)=x²+25
x² + 25 = 0
x²= -25
x = √-25
x = √25i
x = ±5i
⇒(x + 5i) (x - 5i)
c) f(x)=4x²+25
4x²+25 = 0
4x²= -25
x² = -25/4
x = ±√(-25/4)
x = ±(√25i)/2
x = ±5i /2
⇒(x + (5i/2)) (x - (5i/2))
d) f(x)=x²-2x+1
x²-2x+1 = 0
⇒(x - 1)²
e) f(x)=x²-2x+4
x²-2x+4 = 0
x²-2x = -4
x²-2x +1 = -4 +1
x²-2x + 1 = -3
(x-1)² +3 = 0
(x-1)²= -3
x-1 = √-3
x = ±√3i +1
⇒(x +i√3 +1) (x -i√3+1)
Answer:
3/16
Step-by-step explanation:
2 <- 1 and 1(1/4*1/4=1/16)
3 <- 1 and 2,2 and 1(1/2*1/4=1/8)
4 <- 3/16
5 <- 4/16
6<-3/16
Answer:
1
Step-by-step explanation:
Assuming no division by 0, anything divided by itself is 1.
