Step-by-step explanation:
4x-12<16+8x
4x-8x<16+12
-4x<28
x>-7
25-4^2/8=
4^2= 16
16/8= 2
25-2=23
The answer to the first question is 23.
12*5-8/4+7*2=
12*5= 60
8/4= 2
7*2= 14
60-2+14= 72
The answer to the second question is 72.
Number one is 23.
Number two is 72.
Answer: -3
Step-by-step explanation:8-5=3 take the negative so it’s -3
Problem 1
<h3>Answer: D) 2pi</h3>
-------------------
Explanation:
The given table we have is
If you were to graph all those points and draw a cosine curve through them, then the function you should get is
The B coefficient is 1, so that leads to a period of
T = 2pi/B
T = 2pi/1
T = 2pi

Problem 2
<h3>Answer: C)
343.134 yards</h3>
-------------------
Explanation:
Draw out a triangle with these properties
- side a = 270
- side b = 170
- angle C = 100
We'll use the law of cosines to find side c
c^2 = a^2 + b^2 - 2*a*b*cos(C)
c^2 = 270^2 + 170^2 - 2*270*170*cos(100)
c^2 = 117740.902710
c = sqrt(117740.902710)
c = 343.133943
c = 343.134

Problem 3
<h3>Answer: A) 2</h3>
-------------------
Explanation:
If you started with y = sin(x) and applied the transformations stated, then you should end up with
From here, plug in x = 0 to find the y intercept.
Answer:
y = 64
Step-by-step explanation:
To get rid of the 8 in the denominator, you need to do the opposite of the expression. So opposite of division is multiplication. My multiplying each side by 8, you can get rid of the 8 in the denominator. Because if you divide 8 by 8 it is 1.
y = 64
