Function:
f(x) = 2 cos x +1

Note: The values of x should be given in radians.

Therefore;

Substituting for x = 1.5 radians

f(1.5) = 2 Cos 1.5 + 1 ≈ 1.1415

1.1414

Step-by-step explanation:

Given that f is  a function given by

f(x) =2cosx +1

Here x is taken in radians.

Hence when x =1.5

we have cos 1.5 = 0.0707

2cosx = 0.1414

And hence

2cosx+1=1+0.1414

=1.1414

Thus we get

f(1.5) = 1.1414 apprxy

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
