For the quadratic function below, what is the rate of change over the interval.

Mathematics
1 answer:
Darya [45]3 years ago
5 0

Answer:

Step-by-step explanation:

Intervals are always x values. When x = 5, y = 4 (look at the graph to se this); when x = 6, y = 2. The rate of change is the same thing as the slope. We can't get an exact slope here because this isn't a straight line, but we can find the average rate of change. We use the slope formula to do this: with the coordinates (5, 4) and (6, 2):

m=\frac{2-4}{6-5}=\frac{-2}{1}=-2. Third choice down is the one you want.

Ebony is building a shelf to hold the two boxes showed what is the least with she should make the shelf the boxes are 4/5 feet t
Alona [7]

Answer:

  4/5 ft

Step-by-step explanation:

Assuming both boxes need to fit completely on the shelf, Ebony should make it as wide as the largest of the boxes.

In decimal, 4/5 = 0.80 and 3/4 = 0.75, so 4/5 > 3/4.

The shelf should be 4/5 ft wide.

9. A quality-control specialist for an electronics manufacturer estimates that 0.25% of the televisions produced each day by her
aleksandr82 [10.1K]

Answer:

33.75

Step-by-step explanation:

Given that the manufacturer produces an average of 450 televisions each day and 0.25% of the numbers produced each day are defective.

Therefore

0.25% of 450 will give the number of defective televisions produced per day

So

0.25% /100 x 450

0.0025 x 450

1.125

This means that 1.125 of televisions produced each day are defective.

Now to get the estimate of defective televisions in 30 days , multiply the number of defective televisions per day by 30 days seeing that the producer produces an average of 450 each day

So

1.125 x 30

33.75

33.75 televisions are defective in 30 days
