Answer:(theta) =π only
Step-by-step explanation:
-4cos(theta)+1=5
Subtract 1 from both sides
-4cos(theta)+1-1=5-1
-4cos(theta)=4
Divide both sides by -4
-4cos(theta) ➗ -4=4 ➗ -4
cos(theta)=-1
(theta)=cos(inverse)(-1)
(theta)=180
(theta)=π
Yes 4/5 is greater than 0.75 because if you put 0.75 as a fraction that would be 75/100 then you do the same denominator and 5 can go into 100 20 times and so you do that to the numerator and you get 80/100 and 75/100 so 4/5 id grater than 0.75.
Answer:
They are b and c.
Step-by-step explanation:
Let's simplify each expression:
a. b+2 (b+2b)
= b + 2b + 4b = 7b.
b. 3b + b = 4b.
c. 2(2b) = 2 * 2b = 4b.
2/3 reciprocal is 3/2, & 8/3 reciprocal is 3/8. The numbers are just filled to find their reciprocal!
Answer:
4.=11 5.=4 6.=17 7.=47 I think
Step-by-step explanation:
an absolute value of a number is never negative so you just make the number positive and go about the equation normally
