Step-by-step explanation:
20 1/2 = (20×2 + 1)/2 = 41/2.
to create 1/6 of that we have to multiply it by 1/6 :
41/2 × 1/6 = 41/12 = 3 5/12
the rock weighed 3 5/12 lb.
Answer:
The vertex is (2, 3)
Step-by-step explanation:
This is because the parent equation for problems like these is y=a(x-h)2 +k. The vertex is found through (h, k) and so with 2 as H and 3 as K, the vertex is (2,3).
Answer: 112
Step-by-step explanation:
Since we were given m and n, we plug them into the expression and solve.
-2(-6)+4(-5)² [exponent]
-2(-6)+4(25) [multiply]
12+100 [add]
112
Now, we know that the value of the expression is 112.
