Answer:
This is physics. By the way look the explanation.
Step-by-step explanation:
The formula of Potential Energy is E=mgh, where m is the mass of the object, g the gravitational, and h the height of the object. Given that the potential energy of the object is 150 Joules at 3 meters height, Represent m=E/(g*h), considering g=9.8 m/s^2(Because this value was used for the first object), we get m=150/9.8/3=5.102

Answer:
D. $70
Step-by-step explanation:
you can first think that the first tree is $25 plus the nine trees for 5 dollars so
5x9=45
45+25=70
Hope this helps :D
Answer: 30 buttons
Step-by-step explanation:
If there were 8 kids, and 7 more joined, then there were 15 kids making snowmen (8+7 = 15). Each child used 2 buttons for the eyes, so 30 buttons were used (15 x2 = 30). This is assuming no other buttons were used on the snowmen for anything else
Answer:
The value of f(1) is smaller than the value of f(3)
Step-by-step explanation:
<u><em>The correct question is</em></u>
Given the function f(x) = 2x^2 + 3x + 10, find f(1) and f(3). Choose the statement that is true concerning these two values.
The value of f(1) is the same as the value of f(3).
The value of f(1) cannot be compared to the value of f(3).
The value of f(1) is larger than the value of f(3).
The value of f(1) is smaller than the value of f(3)
we have

step 1
Find out the value of f(1)
substitute the value of x=1 in the function f(x)
so
For x=1


step 2
Find out the value of f(3)
substitute the value of x=3 in the function f(x)
so
For x=3


step 3
Compare the values
37> 15
so
f(3) > f(1)
or
f(1) < f(3)
therefore
The value of f(1) is smaller than the value of f(3)
