Answer:
5x-4y+4
Step-by-step explanation:
3x-4y-2+2x+6
Gathers like terms together:
3x+2x= 5x
-4y= -4y
-2+6= 4
Put it together:
5x-4y+4
To the nearest tenth is 290 and to the nearest hundreth is 300
Answer:
<1 = 93 (vertical opposite angle are equal)
Step-by-step explanation:
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:
Step-by-step explanation:
tax = 1/20 of price
1/20 of $3 = 1/20 × 3 = 3/20 = $0.15
1/20 of $800 = 1/20 × 800 = $40
