Write a function rule that represents the sentence. y is 8 less than the product of 7 and x.

Bas_tet [7]

Answer:

$f(x) = 7x - 8$ or

$y = 7x - 8$

Step-by-step explanation:

Let x be the input and f(x) or y represent output.

The function in this case is given as firstly we will take seven times of the input and subtract eight to it, to obtain the required output.

$y = 7x - 8\\or\\f(x) = 7x - 8$

What is the measure of angle R?

Alika [10]

Answer:

m<R = 22.62°

Step-by-step explanation:

Reference angle = R

Opposite = 5 cm

Hypotenuse = 13 cm

Apply the trigonometric function SOH:

Sin R = Opp/Hyp

$Sin (R) = \frac{5}{13}$

$R = sin^{-1}(\frac{5}{13})$

R = 22.6198649°

m<R = 22.62° (nearest hundredth)
