Engineers are analyzing the performance of windshield wiper blades. at the end of one swipe, the tip of a blade is at (−5, 7) when represented graphically. what is the sine value of this function? (2 points) negative 7 square root 74 divided by 74 negative 5 times square root of 74 over 74 7 times square root of 74 over 74 square root 74

Option C.

Step-by-step explanation:

At the end of one swipe the tip of one blade is at (-5, 7). We have to find sine value of this function.

As shown in the figure coordinates of the tip of the wiper blade are (-5, 7)

So

Here Height of the triangle = 7

and Hypotenuse = x =

By putting these values in the expression

Answer is option C.

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
