Mustafa is staring at a pizza spinning on a wheel in a glass case. The pizza is cut into four even slices. The distance P(t)P(t)P, left parenthesis, t, right parenthesis (in \text{cm}cmstart text, c, m, end text) between the center of the tastiest looking slice and the door of the glass case as a function of time ttt (in seconds) can be modeled by a sinusoidal function of the form a\cdot\cos(b\cdot t)+da⋅cos(b⋅t)+da, dot, cosine, left parenthesis, b, dot, t, right parenthesis, plus, d.
At t=0t=0t, equals, 0, the center of the tastiest looking slice is farthest from the door, at a distance of 30\text{ cm}30 cm30, start text, space, c, m, end text away. After 2\pi2π2, pi seconds, it is closest to the door, at a distance of 10\text{ cm}10 cm10, start text, space, c, m, end text.
Find P(t)P(t)P, left parenthesis, t, right parenthesis.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

how am i supposed to answer

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
