Answer:
B. 44°
Step-by-step explanation:
Central angle = 3x + 10°
Inscribed angle = 2x - 17°
Now
Central angle = 2 * inscribed angle
( Central angle is double of the inscribed angle standing on same arc)
3x + 10° = 2 ( 2x - 17°)
3x + 10° = 4x - 34°
4x - 3x = 34 ° + 10°
x = 44°
Hope it will help :)❤
Given:
The function is
Domain = {-4, -2, 0, 2}
To find:
The range of the given function for the given domain.
Solution:
We know that domain is the set of input values and range is the set of output values.
We have, and domain = {-4, -2, 0, 2}.
Putting x=-4 in the given function, we get
Putting x=-2 in the given function, we get
Putting x=0 in the given function, we get
Putting x=2 in the given function, we get
The output values are -7, 1, 9, 17. So, the range of the function f(x) for the given domain is {-7, 1, 9, 17}.
Therefore, the correct option is D.
11. 180-73 = 107
10. 180-107=73
12. 180-73=107
13. 5x + 20 + B = 180 -> B = 180 - 20 - 5x and 3x+66 + B = 180 -> 3x+66+ (180 - 20 - 5x) = 180 -> 222-180 = 2x -> x = 21
14. ABC = 5x + 20 = 5*21+20= 125
15. ABE = 3x+66 = 3*21+66 = 129
The square root of 36 is 6. Good luck.
Answer:
Harry swims at 1.6 laps per minute and Larry swims at 1.8 laps per minute. Henry swims at a slower rate than Larry.
Step-by-step explanation:
i dont know for sure if this is right or not but i think it is. i mean for Henry the only number i have is 1.6 and so if that is going to be multiplied by x which is his minutes i would guess that that is the rate he is swimming at per minute. and as for larry, i took 4.5 (which is his laps) and divided it by 2.5 (which is his time) to get how many laps per minute he swims. i got 1.8. 1.6 is slower than 1.8 so therefore, i concluded that harry swam at a slower rate than larry.
