Answer:

-14/3

Step-by-step explanation:

Use derivative = 0 to find turning point(S)

D f(x) = 3x + 10 = 0

3x = - 10

X = - 10/3

When X = - 10/3

F(x) = 1.5(10/3)^2 - 10(10/3) + 12

= (3*10*10) / (2*3*3) - 100/3 +12

= 50/3 - 100/3 + 36/3

= - 14/3

What’s the value of 27.43? Write answer in a fraction

Nezavi [6.7K]

Answer:

As an improper fraction: 27 $\frac{43}{100}$

As a mixed fraction: $\frac{2743}{100}$

Step-by-step explanation:

Any number could be expressed as a fraction 27 is $\frac{27}{1}$ and since 0.43 is forty-three hundredths we can express it as $\frac{43}{100}$ .

To find the answer as a mixed fraction we have to put the whole number in the beginning and the fraction in the end. 27 $\frac{43}{100}$

As an improper fraction we have to add 27 / 1 + 43/100 = $\frac{2743}{100}$
