Sin is opposite over hypotenuse, so sin(A) = 4/5. Cos its adjacent over hypotenuse, so cos(A) = 3/5
Answer:
<em>( 4, 11 ) , ( - 4, 27 ) </em>
Step-by-step explanation:
f(x) = x² - 2x + 3
f(x) = - 2x + 19
x² - 2x + 3 = - 2x + 19
x² - 16 = 0
( x + 4 )( x - 4 ) = 0
= - 4
= 4
f(x) = 
= - 2( - 4 ) + 19 = 27
= 27
f(x) = 
= - 2( 4 ) + 19 = 11
= 11
<em>( 4, 11 ) , ( - 4, 27 )</em>

Step-by-step explanation:
An exponential function is a mathematical function of the following form: f ( x ) = a x. where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e , which is equal to approximately 2.71828.
