Answer:

y ≈ 61

Step-by-step explanation:

Using the Sine rule in the triangle

\frac{y}{sin117} = \frac{21}{sin18} ( cross- multiply )

y × sin18° = 21 × sin117° ( divide both sides by sin18° )

y = \frac{21sin117}{sin18} ≈ 61 ( to the nearest whole number )

Given that (5,4) is on the graph of f(x), found the corresponding point for the function f (x)+4
yarga [219]

Answer:

The corresponding point is (5,8)

Step-by-step explanation:

In this problem we know that

The rule of the transformation is equal to

(x,f(x)) ------> (x,f(x)+4)

so

for the point (5,4)

x=5, f(x)=4

substitute

(5,4) ------> (5,4+4)

(5,4) ------> (5,8)

therefore

The corresponding point is (5,8)
