Evaluate Sin^-1 sqrt2/2
Step-by-step explanation:
Let x = arcsin(√2/2).
We have sinx = √2/2, which is a basic trignometry identity. (sin45° = √2/2)
Since the range of arcsinx is [-90°, 90°] and 45° is within the range, the answer is 45° or π/4.

Answer: x= 10, y= 13. i dont know for sure so i'd wait for someone else to answer
Answer:
x = 12
y = 13
Step-by-step explanation:
by pythagoras theorem
x²=20²-16²
x²=400-256
x²=144
x=12
y²=x²+5²
y²=12²+5²
y²=144+25
y²=169
y=13
help please due soon
Answer:
y = 6x
Step-by-step explanation:
You can easily find the slope by using slope formula:
(y2-y1) / (x2-x1) (the numbers are subscript)
E.g: (24-12) / (4-2) = 12/2 = 6
m(slope) = 6
Hope this helped :)
(You can also check if it’s correct by inputting the coords into the equation, seeing if all solutions are aplicable).
Please solve, will mark brainliest
Answer:
The slope is undefined
Step-by-step explanation:
Answer:
Zero
Step-by-step explanation:
x-value remains at zero. This means the line is horizontal, so slope is zero.

A trapezoid has a base 1 = 6 base = 8 and a height = 3 whats the area?
Answer:
[tex]area = 21[/tex]
Step-by-step explanation:
Area of trapezoid formula:
[tex]area = \frac{a + b}{2} h[/tex]
Given information:
a: 6
b: 8
h: 3
Using the given information,
[tex]area = \frac{6 + 8}{2} 3[/tex]
Add the numbers in the numerator
[tex]area = \frac{14}{2} 3[/tex]
Reduce fraction with 2
[tex]area = 7 \times 3[/tex]
Answer:
[tex]area = 21[/tex]

The Singleton family is looking to rent a large truck for their upcoming move. With Erin's Moving, they would pay $41 for the first day plus $5 per additional day. With Greenpoint Rent-a-Truck, in comparison, the family would pay $31 for the first day plus $7 per additional day. Before deciding on which company to use, Mrs. Singleton wants to find out what number of additional days would make the two choices equivalent with regards to cost. What would the total cost be? How many additional days would that be?
Answer:
6days
total cost-$66
additional days-5

If forces are unbalanced, what will happen to the object (horse)?
Answer:
Newton's 2nd Law says that an object accelerates if there is a net (unbalanced) force on it. Looking at the wagon in the diagram above, you can see that there is just one force exerted on the wagon - the force that the horse exerts on it. The wagon accelerates because the horse pulls on it!

70% of the tickets sold at a school carnival were early-admission tickets. If the school sold 80 tickets in all, how many early-admission tickets did it sell?
The school sold 56 early admission tickets.
Step-by-step explanation:
To figure this out, you can multiply 80 by 0.7 and get the amount of early admission tickets that way.
If you wanted too, you could also do it by figuring out what 10% of 80 is (which is 8) and multiply that by 7 if that's easier for you.

5x + 3x = 5x + 6 What value of 3x makes the equation true?
Answer:
-45 (9x-20) - 3x = 45x-6
-405x+900-3x = 45x-6
-408x+900 = 45x-6 (combine like terms)
906=453x (add 6 to 900 and - 408x to 45x)
2=x (divided )
X=2
