Answer:
zinc = 152 grams
Step-by-step explanation:
Ratio of zinc to copper = 4 : 15
Copper = 570 grams
zinc = x grams
Find x
Ratio of zinc to copper = x : 570
Equate both ratios
4 : 15 = x : 570
4/15 = x/570
Cross product
4 * 570 = 15 * x
2,280 = 15x
x = 2,280/15
= 152
x = 152 grams
zinc = 152 grams
The bottom one since as x increases so does y. the top function doesn't since it's a quadratic. meaning it decreases and hen increases
ANSWER:
STEP-BY-STEP EXPLANATION:
We have the following function
Now, we calculate for each case the result of the function.
a) g(6)
b) g(3)
c) g(-4)
d) g(-15.75)
e) g(x+h)
Answer:0.15d+30<_100
Step-by-step explanation:
Substituting the data points into the model:
f(x)= -x2 + 2x -3
f(-2)=-11
f(0)=-3
f(1)=-2
f(3)=-6
f(5)=-18
So A is the right ans.
