Answer: $34.13
explanation:
4 • $9.99 = $39.96 before tax or discount
subtract discount:
$39.96 • 0.2 = $7.992
39.96-7.992 = 31.968
add tax:
31.968 • 1.0675
= $34.13
Answer:
-3
Step-by-step explanation:
f(x) =-5x+7, find f(2)
f(2) = -5(2) + 7, multiply -5(2)
f(2) = -10 + 7, add -10 + 7
f(2) = -3
Answer:
The equation is true
Step-by-step explanation:
The best way to check if this equate is true is to convert the pi in radians to degree and actually evaluate the trigonometric terms.
Mathematically we know that pi = 180 degrees
So pi/8 = 22.5
and pi/4 = 180/4 = 45
So let’s make our check.
Insert pi = 22.5 and pi = 45
So we have;
tan 22/5 = √(1-cos45)/(1+cos45)
Now let’s evaluate this using a calculator.
tan 22/5 = 0.414213562373
The term in the root; 0.171572875254
The square root of this number is
0.41421356237
This is exactly as what is obtained with the tan 22.5
So we conclude that what we have is true
