Calculator display for $\frac{9}{12}$ = 0.75

calculator display for $\frac{5}{12}$ = 0.41667

Calculator display for $\frac{7}{12}$ = 0.5833

Step-by-step explanation:

Calculator display for $\frac{9}{12}$ is 0.75

Yes , it is the exact decimal equivalent.

$\frac{9}{12}$ = 0.75

9 ÷ 12

=3 ÷ 4

= (3 × 25) ÷( 4 × 25)

= 75 ÷ 100

= 0.75

calculator display for $\frac{5}{12}$ = 0.41667

$\frac{5}{12}$ = 0.41667

It is not the exact decimal equivalent.

5 ÷ 12 = (5 × 8.35) ÷ ( 12 × 8.35)

= 41.75 ÷ 100.2

= 0.41667

Calculator display for $\frac{7}{12}$ = 0.5833

It is not the exact decimal equivalent.

7 ÷ 12 = ( 7 × 8.35) ÷ ( 12 × 8.35)

= 58.45 ÷ 100.2

= 0.5833

If f(x) = 8x2 + 4x - 12. Find f(2)<br> f(2)=

posledela

Answer:

f(2) = 28

Step-by-step explanation:

$\rm f(x) = 8 {x}^{2} + 4x - 12$

$\rm Evaluate \: 8 x^2 + 4 x - 12 \: where \: x = 2: \\ \\ \rm \implies f(2) = 8 \times {2}^{2} + 4 \times 2 - 12 \\ \\ \rm \implies f(2) = 8 \times 4 + 8 - 12 \\ \\ \rm \implies f(2) = 32 - 4 \\ \\ \rm \implies f(2) = 28$
