Mathematics
1 answer:
Arturiano [62]3 years ago
4 0

Answer:

Sophia has considered the coefficient of x² as 1 in place of 16 and coefficient of x as 10 in place of - 40 in the original trinomial.

Step-by-step explanation:

The given trinomial to be factorized into a perfect square is 16x² - 40x + 25.

And Sophia obtained the perfect square as (x + 5)² which gives the trinomial as x² + 10x + 25.

Therefore, Sophia's work is not correct as 16x² - 40x + 25 ≠ x² + 10x + 25.

Therefore, Sophia has considered the coefficient of x² as 1 in place of 16 and coefficient of x as 10 in place of - 40 in the original trinomial and then factorized the wrong trinomial as (x + 5)². (Answer)

What is the vertex of the quadratic function?
viktelen [127]

Answer:

The vertex is (6, -4)

Step-by-step explanation:

f(x) =(х – 8)(х – 4)

First find the zeros

0 = (х – 8)(х – 4)

0 = x-8      0 =x-4

x=8          x=4

The zeros are x=8 and x=4

The vertex is 1/2 way between the zeros

(8+4)/2 = 12/2 =6

To find the y value, substitute 6 into the function

f(6) = (6-8) (6-4)

     =  -2 (2) = -4

The vertex is (6, -4)

A child requires a 5ml dose of medicine each day. how many days would a gallon of this medicine last.
OLga [1]

in a US gallon, there are approximately 3.79 Liters, in a Liter there are 1000 milliLiters, so 3.79 Liters is then 3.79 * 1000 milliLiters, namely 3790 milliliters.

since a gallon is then approximately 3790 mL, how many times does 5mL go in to 3790? 3790 ÷ 5 = 758.

since the child uses 5mL in 1 day, then 758 times that is 758 days.
