Answer:

3.9%

Step-by-step explanation:

Percentage error

=  \frac{7.7 - 7.4}{7.7}  \times 100 \\  \\  =  \frac{0.3}{7.7}  \times 100 \\  \\   =  \frac{300}{77}  \\  \\  = 3.8961039    \\  \\  = 3.9 \%

Hi there! The answer is A.

t = 2(s + 2)
To get a proper idea of the type of function this formula represents we work out the parenthesis.

Working out the parenthesis can for instance be done using rainbow technique.
t = 2s + 4

We can now see sinilarities between this function an the general function of a line in slope intercept form
y = mx + n

The function t therefore describes a line with slope 2 and y-intercept 4. Therefore the answer is A.
