Answer:

Step-by-step explanation:

The first statement, the fourth statement, and the fifth statement are true. The others are not.

In vertex form, looking at the first statement, you can see that the vertex is located at (4, -11), NOT (-8, 5)

The (x - 4)^2 binomial gives you the axis of symmetry, which is x = 4, NOT x = 5.

5. One canned juice drink is 15% orange juice; another is 10% orange juice. How many liters of each should be mixed together in

hram777 [196]

X: liters of 15% orange juice
y: liters of 10% orange juice

x+y=5L

y=5L - x

x liters of 15% orange juice plus y liters of 10% orange juice makes 5 liters of 12% orange juice in equation form:

0.15x+0.10y = 0.12(5L)

0.15x+0.10(5L-x)=0.12(5L)

0.15x+0.5-0.10x=0.6

0.05x=0.1L

x=2L

so y = 3L

so you need 2 liters of 15% orange juice and 3 liters of 10% orange juice

The circumference of Circle F is 72 cm. What is the length of Arc DE (the minor arc)?

Tom [10]

You need to first set up the equation:

It would look like 90 divided by 360 multiplied by the given circumference which is 72 cm.

So 90 / 360 x 72

Simply the fraction above, it will give us:

¼ x 72

So the answer would be 18 cm that is the length of DE (minor arc)
