Answer:

a) φ = 4/7

b) φ = 4

Step-by-step explanation:

The relationship between radius, angle, and arc length is ...

a = r·φ . . . . . φ in radians

You want to find the angle φ, so you can divide this equation by r:

φ = a/r

a) φ = a/r = (8 cm)/(14 cm) = 8/14

φ = 4/7 radians

b) φ = a/r = (16 cm)/(4 cm) = 16/4

φ = 4 radians

Solve quadratic equation (x-3)^2+5=14

loris [4]

(X-3)^2+5=14
Step 1: simplify both sides of the equation
X^2-6x+14=14

Step 2: subtract 14 from both sides
X^2-6x+14-14=14-14
X^2-6x=0

For this equation: a=1, b=-6,c=0
1x^2+-6x+0=0

Step 3: Use quadratic formula with a=1, b=-6, c=0

The answer is x=6 or x=0

How would the number of times edgardo uses a container to fill the 10 gallon cooler change if he uses a one cup container? Expla

Answer:

Edgardo would use the container 160 times to fill.

Step-by-step explanation:

Given:

Edgardo uses a container to fill the 10 gallon cooler.

If he uses a one cup container.

Now, to find the times it would take to fill the 10 gallon container.

As, the capacity of container = 1 cup.

And, the capacity of cooler = 10 gallon.

So, we use conversion factor to find the times the container to fill the cooler:

1 gallon = 16 cups.

10 gallon = $10\times 16\ cups.$

10 gallon = 160 cups.

Thus, to fill the 10 gallon cooler 160 cups of container needed.

And, the container is of 1 cup.

So, to get the times he would use the container we divide 160 by 1:

$160\div 1=160.$

Hence, 160 times Edgardo would use the 1 cup container to fill the 10 gallon cooler.

Therefore, Edgardo would use the container 160 times to fill.
