cos (75)=cos (15) nothing square and check
2/5 van not be simiplified because 2 and 5 dont have a common factor lower than them
Answer:
Step-by-step explanation:
divide by 2 and square it
y+axSQUARED +bx+ c ----->(b/2)squared +d
2 ) add and subtract d to the equation
y = (axSQUARED +bx +d ) + c -d
factor the first part of the equation to match the vertex form and simplify
y= a(x-h)SQUARED + c- d
Y = a ( x - h SQUARED + k
24
Because it we have to find x....
Number 1. is 1/5 but in decimal form it’s 0.2
