Answer:
option D
Step-by-step explanation:
2/3x=26
multiply both sides by 3/2 to get x by itself
2/3x(3/2)=26 (3/2)
Cross out 2s and 3s. Divide by 2 and 3.
Then becomes 1*1*1*1*x=x
26(3/2)
Cross out 26 and 2. Divide by 2.
26/2=13
2/2=1
13*3=39
Answer:
x=39
Answer:
x² + (y-74)² = 4900
Step-by-step explanation:
Circle equation: (x-h)² + (y-k)² = r²
"h" refers to horizontal shifts while "k" refers to vertical shifts. If the center of the wheel is directly above the origin of the rectangular plane and the entire wheel is 4 ft. from the ground then:
- h = 0
- k = 74 (the radius + 4 ft.)
- r = 70
So plugging those into the equation of circles, we get the answer above.
Correct Answer:
Option 3. The quadratic function has two distinct real zeros.
The number of distinct real zeros of a function is equal to the number of x-intercepts of the function. In this case the quadratic function has 2 x-intercepts at 2 different places, this signifies that the function has 2 real zeros. Since the function is quadratic it can have only 2 zeros.
The knowledge of y-intercept is extra and has nothing to do with the number of zeros of the function.
