If the discriminant is 16 in a quadratic equation what is true about its solutions

olganol [36]

If the discriminant is a positive number, there will be 2 possible solutions. If you replace the entire section of b²-4ac with 16, you will see that the equation becomes; (-b+-√16)/2a --> leading to an answer with the + and another with the -.

If the discriminant is 0, there will be 1 possible solution, (again replace this into the discriminant value) (-b)/2a ---> this formula is used to also find the x coordinates of a vertex, fyi.

If the discriminant is a negative number, there will be no solution (since squareroot of a negative number is not possible)

Hope I helped :)

Richard’s store sells pineapples and grapefruits. Pineapples originally cost $5.15 apiece, and grapefruits originally cost $2.25

sveta [45]

Answer:

c. The price of grapefruits experienced a reduction 6.01 percentage points greater than the price of pineapples.

Step-by-step explanation:

The original price of Pineapples=$5.15

New price of Pineapples=$3.88

Find change in price of Pineapples

Change in price=original price- new price

$=5.15-3.88=1.27$

The price of Pineapple was reduced by $1.27

% reduction in price

(reduction value/original value) × 100

$=\frac{1.27}{5.15} *100=24.66$

=24.66%

The original price of grape fruits=$2.25

New price of grape fruits=$1.56

Change in price of grape fruit

Change in price= original price -new price

$=2.25-1.56=0.69$

% reduction in price of grape fruits

(reduction value/original value)×100

$=\frac{0.69}{2.25} *100=30.67$

=30.67%

Answers

The fruit that has its price reduced by a greater percentage is grape fruit

How many percentage points greater = 30.67%-24.66% = 6.01 points
