No it’s not. 1/4 of 126 is 31.5.
To get this you need to do 126/4
Answer:
the answer is she had $4.40 left.
Step-by-step explanation:
1) 40x1.50=<u>60</u> 2) 40x0.89= <u>35.6</u> 3) 60+35.6= <u>95.6</u> 4) 100- 95.6= <u>$4.4</u> I hope this helps if not sorry. :)
Cos Ф - cos Ф.sin² Ф
sin² Ф = 1 - cos² Ф
cos Ф - cos Ф( 1-cos² Ф) = cos Ф - cos Ф - cos³ Ф = cos³ Ф
cos Ф - cos Ф.sin² Ф = cos³ Ф
Answer:
w^64
Step-by-step explanation:
(w^8)^8
both of the powers will be multiplied; hence
w^8*8
w^64
Answer: 4.5
<u>Step-by-step explanation:</u>
First, find the points of intersection by solving the system.
y = x² + 2x + 4
y = x + 6
Solve by substitution:
x² + 2x + 4 = x + 6 ⇒ x² + x - 2 = 0 ⇒ (x + 2)(x - 1) = 0 ⇒ x = -2, x = 1
Now, integrate from x = -2 to x = 1
<em>the bottom of the integral is -2 </em>
=
=
= 
= 
= 
= 
= -3 + 1.5 + 6
= 4.5
