The answer is A) because the parabola is less than 3 (open circle) and the line is greater than and equal to 3 (closed circle)
Answer: 36 ft^2
Step-by-step explanation: 4x3/2=6. 6x2=12. 3x2=6. 4x2=8. 5x2=10. 12+8+6+10=36
Answer:
an=9+(n−1)3, an=3n+6
Step-by-step explanation:
Arithmetic Sequence:
d=3
This is the formula of an arithmetic sequence.
an=a1+d(n−1)
Step 1: Substitute in the values of
a1=9 and d=3.
an=9+(3)(n−1)
Step 2: Simplify each term.
an=9+3n−3
Step 3: Subtract 3 from 9.
an=3n+6
105° can be expressed as 60°+45°. What we have then is sin(60°+45°). The sum pattern for sin is sin(a)cos(b)+cos(a)sin(b). We will fill in as follows: sin(60)c0s(45)+cos(60)sin(45). Now draw those special right triangles in the first quadrant to get the exact values for each. The sin of 60 is

, the cos of 45 is

, the cos of 60 is 1/2, and the sin of 45 is

. When we put all that together we get

. Simplifying all of that we have

. We can put that over the common denominator that is already there and get

. Not sure if that's simplified enough; you may be at the point in class where you are rationalizing your denominator, but I'm not sure, and if you're not, I don't want to confuse you.
Answer:
x = 3/4 or 0.75
Step-by-step explanation:
Break the bracket out and you will get:
3(5x – 4) – 2 = 10 – 3x
= 3*5x - 3*4 - 2 = 10 - 3x
= 15x - 12 -2 = 10 -3x
Add 3x into both sides and subtract 12 and subtract 2 in both sides, we get:
15x + 3x - 12 - 2 + 12 - 2 = 10 - 3x + 3x + 12 + 2
18x = 24
Divide both side by 18, we get:
18x/18 = 24/18
x = 24/18 = 3/4 or 0.75
Hope this helped :3
