Answer:
a. -29
b. 7
c. 7.04
d. 1/6
Step-by-step explanation:
Here, we want to calculate the difference between the numbers;
a. -8 and 21
That would be -8-21 = -29
b.-87 abs -94
= -87-(-94)
-87 + 94= 7
c. 1.8 and -5.24
= 1.8 -(-5.24)
= 1.8 + 5.24 = 7.04
d. 1/3 and 1/6
= (2-1)/6 = 1/6
Answer:it has two
Step-by-step explanation: x =(3-√89)/4=-1.608
x =(3+√89)/4= 3.108
Given:
Consider the height of the rocket, in feet after x seconds of launch is
To find:
The time at which the rocket will reach its max, to the nearest 100th of a second.
Solution:
We have,
It is a quadratic polynomial with negative leading coefficient. So, it is a downward parabola.
Vertex of a downward parabola is the point of maxima.
To find the time at which the rocket will reach its max, we need to find the x-coordinate of the vertex.
If a quadratic function is , then the vertex is
Here, .
So,
So, x-coordinate of the vertex is 4.75.
Therefore, the rocket will reach its max at 4.75 second.
The infield of a baseball stadium is diamond shaped, which means each side is the same length.
If the whole area of the diamond is 81 inches, then each side has to be 9 inches.
A = b²
81 = b²
√81 = b
9 = b
The answer is 25 points
The equation would be : 3x+5y+6z
3*3= 9
5*2= 10
6*1= 6
9+10+6= 25
