Can someone help me with this question please! I have nooo idea how to complete it!
natulia [17]

Answer:

y = 3\sqrt{2} + 4

Step-by-step explanation:

Create 2 equations using values from the table to find a and b.

Using (0, 10), then

10 = acos0° + b ( cos0° = 1 ), thus

a + b = 10 → (1)

Using (90, 4), then

4 = acos90° + b ( cos90° = 0 ), thus

b = 4

Substitute b = 4 into (1)

a + 4 = 10 ( subtract 4 from both sides )

a = 6

Thus

y = 6cosx° + 4

When x = 45°, then

y = 6cos45° + 4 = 6 × \frac{\sqrt{2} }{2} + 4 = 3\sqrt{2} + 4
