Answer: 7.84 is the answer
Answer:
The height of the curve at every point is the line value of the sine. In the language of functions, y = sin x is an odd function.
Step-by-step explanation:
Answer:
∠ 3 = 55°
Step-by-step explanation:
∠ 2 and ∠ 7 are corresponding angles and are congruent, then
5x - 60 = 3x + 14 ( subtract 3x from both sides )
2x - 60 = 14 ( add 60 to both sides )
2x = 74 ( divide both sides by 2 )
x = 37
∠ 2 = 3x + 14 = 3(37) + 14 = 111 + 14 = 125°
∠ 2 and ∠ 3 are adjacent angles on a straight line and sum to 180° , so
125° + ∠ 3 = 180° ( subtract 125° from both sides )
∠ 3 = 55°
I'll solve one from each kind
Q1)
6 = a/4 + 2 <em>(mutiply both sides)</em>
24 = a + 8 <em>(move the terms)</em>
-a = 8 - 24 <em>(calculate)</em>
-a = 8 - 16 <em>(change the signs)</em>
a = 16
Q8)
2( 2 + 5) = -2 <em>(divide both sides)</em>
n + 5 = -1 <em>(move the constant to the right)</em>
n = -1 - 5<em> (calculate)</em>
n= -6
Q3)
9x - 7 = 7 <em>(cancel equal terms)</em>
9x = 0 <em>(divide both sides)</em>
x = 0
If you multiply 38.95 by 0.02, you will get the amount taken away from the total when the discount is applied:
38.95x0.02=0.78
Then, you subtract that discount price from the total to get the amount Joan pays when she pays with cash:
38.95-0.78=35.17
Joan pays $35.17 in cash.
