Answer:
every number you can think of
Step-by-step explanation:
6x - 3y = -6
=> 3(2x - y) = -6
=> 2x - y = -2
And you see there's a problem here. The question doesn't have enough information because x and y can be every numbers.
Take an example, x can be 200 and y can be 402 or x can be 5 and y can be 12.
Rewrite or check the question again so I can solve this :)
The is answer is definitely D, because he computed the total population of 3,320 in the survey of his targeted people that he specified which was grade school and high school. In order for his computation to work for his market analysis he used the radius of 5m and the 75% he wanted to achieve.
Answer:
Step-by-step explanation:
Square the base, height and hypotenuse
add the base and height together and if it equals the hypotenuse it is a right triangle
example:
base = 3, height = 4, hypotenuse = 5
3^2 + 4^2 = 9 + 16 = 25
5^2 = 25
25 = 25 so that would be a right triangle.
Step-by-step explanation:
General form of a sine or cosine wave is:
y = ±A sin((2π/T) t) + B
y = ±A cos((2π/T) t) + B
where A is the amplitude, T is the period, and B is the vertical offset or midline.
The Ferris wheel is 80 meters in diameter or 40 meters in radius.
A = 40
The Ferris wheel turns once every 8 minutes.
T = 8
The lowest point is 5 meters above the ground, so the center of the Ferris wheel is 45 meters above the ground.
B = 45
At t=0, you're at the lowest point, so use -cos.
Therefore, the equation is:
y = -40 cos(2π/8 t) + 45
y = -40 cos(π/4 t) + 45
When t = 5:
y = -40 cos(5π/4) + 45
y = 20√2 + 45
y ≈ 73.3 meters
When y = 35:
35 = -40 cos(π/4 t) + 45
-10 = -40 cos(π/4 t)
1/4 = cos(π/4 t)
π/4 t ≈ 1.318
t ≈ 1.68 minutes
