Answer:
It hit the ground at t=2
It reaches its highest point at t=1
Its maximum height =16
Step-by-step explanation:
The graph of the function of the height will be a parapola opening downward where it's x intercepts = the time where the object hit the ground and its maximum point = the point with the maximum point
The x intercepts are 0 when the object was thrown and 2 when it landed
The x coordinate of the vertex is in the middle of the two x intercepts so it will be 1
Substituting the x coordinate of the vertex gives us the y coordinate of the vertex which is the maximum hight 16
Answer:
130 women
Step-by-step explanation:
First set up a system of equations:
1.23W+2.50M=365.00
W+M=211
Using substitution you get:
1.25W+2.50(211-W)=365.00
Simplify:
-1.25W=-162.5
Divide:
W=130
Answer:
The area of the surface that needs to be iced is 480 m².
Step-by-step explanation:
A cake has the same shape as a rectangular prism. A rectangular prism has six faces. The first one is formed by the length and the width, the second is formed by the length and the height and the third is formed by the width and the height, each of these faces is mirrored, so the surface area for the cake is:
surface area = 2*width*height + 2*width*length + 2*length*height
surface area = 2*12*4 + 2*12*12 + 2*12*4
surface area = 96 + 288 + 96 = 480 m²
The area of the surface that needs to be iced is 480 m².
Answer:
swing state
noun
a US state where the two major political parties have similar levels of support among voters, viewed as important in determining the overall result of a presidential election.
Step-by-step explanation:
Standard deviation is the square root of the variance.
To find the variance from the standard deviation, raise it to the 2nd power:
Standard deviation = 4
Variance = 4^2 = 4x4 = 16.
