What is the height of an object thrown when time is 6 seconds? Also explain how u got your answer

nevsk [136]

Answer:

$946.4\ m$

Step-by-step explanation:

Let

h(t) ---> the height of an object in meters

t ----> the time in seconds

we have

$h(t)=-2.6t^2+40t+800$

For t=6 sec

substitute in the quadratic equation the value of t and solve for h

$h(6)=-2.6(6)^2+40(6)+800$

$h(6)=946.4\ m$

The rectangles below are similar in shape. How wide is the smaller rectangle?

Amanda [17]

Answer:

$\huge\boxed{x=28\ ft}$

Step-by-step explanation:

If two rectangles are similar, then corresponding sides are in proportion.

Therefore we have the equation:

$\dfrac{x}{42}=\dfrac{36}{54}$

cross multiply

$54x=(42)(36)\\\\54x=1512$

divide both sides by 54

$\dfrac{54x}{54}=\dfrac{15212}{54}\\\\x=28$
