Find becky's mistake Choose 1

ss7ja [257]

Hi there!

mistake= step 2..

If you can see, the equation is the opposite so this means that to find the answer, your gonna have to add first.. instead of subtracting..

1.Add the terms:

$7+\frac{5}{4}=7\frac{5}{4}$

2.Simplifly the terms:

$7\frac{5}{4}=7\frac{25}{20}$

$\frac{4}{5}=\frac{16}{20}$

3.Subtract the terms:

$7\frac{25}{20}-\frac{16}{20}=7\frac{9}{20}$

Therefore, the mistake was step 2...

Step-by-step explanation:

An equation that is perpendicular to another equation must have the opposite slope. In other words, the perpendicular equation will be the opposite sign & the reciprocal of the equation it is perpendicular to. In this case, the perpendicular slope is -5/2x. Therefore, the only answer possible is a.

Please answer this question

alisha [4.7K]

Answer:

36.

Step-by-step explanation:

sec^2 (π/9) = 1 / cos^2 (π/9) = 1.13247

sec^2 (2π/9) = 1 / cos^2 (2π/9) = 1.70409

sec^2 (4π/9) = 1 / cos^2 (4π/9) = 33.1634

Adding these gives us 36 to the nearest whole number
