3. how is C(10) different from C(x) = 10?

Answers

Answer:

Step-by-step explanation:

1. C(10)=35  is the percentage of homes using only cell phone service 10 years after 2004, that is, after 2014.

2. C(x) = 10  is the percentage of homes using only cell phone service x years after 2004.  We must find x.

3. how is C(10) different from C(x) = 10?

In C(10), 10 measures time in years and is the independent variable here; C10) is the dependent variable.  See (2), above.  In C(x), x is the (unknown) independent variable, whereas 10 is the output vaue, the dependent variable.

Answer:

b=9 and b=-21

Step-by-step explanation:

first step: move 195 to the other side by adding to get:

b^2+12b=189

now to find the constant you take the b value which is 12 divide that by 2 and square it. then add the product to both sides. 12/2=6, 6^2=36

b^2+12b+36=189+36

next factor b^2+12b+36.

(b+6)^2=225

square root both sides to get:

b+6=15 and b+6=-15

solve by subracting 6 to both sides and you get the 2 final answers.

b=9 and b=-21

Kiran has 2 & 3/4 pounds of flour. When he divides the flour into equal-sized bags, he fills 4 & 1/8 bags. How many pounds fit in each bag?

Answers

Answer:

The number of pounds that will fit in each bag is 2/3 pounds of flour

Step-by-step explanation:

Here, we want to know the amount of pounds that will fit in each bag

What we have to do here is to divide the total number of pounds of flour, by the number of bags filled

We have this as;

2 3/4 divided by 4 1/8

This is;

11/4 divided by 33/8

= 11/4 * 8/33 = 2/3 pounds

Answers

Answer: It's a B answer.

Show your work here:

In an ordered pair the first coordinate is x the coordinate, and the second coordinate corresponds to the y coordinate.

Then we must substitute the given value of x in the equation and verify that we get in return the defined value for y.

the options are (-2,4)

in this one x=-2, and y=4, so let's confirm:

y=-3x-4

y=-3(-2)-4

y=-6-4

y=2

this is not a solution since the y values are not the same.

in this one x=-3 and y=5, let's also confirm:

y=-3(-3)-4

y=9-4

y=5

in this one the values for y are equal, this is a solution for the equation.

In circle D with m \angle CDE= 60m∠CDE=60 and CD=3CD=3 units, find the length of arc CE. Round to the nearest hundredth

Answers

Answer:

Length of arc CE = 3.14 unit (Approx.)

Step-by-step explanation:

Given:

Radius of circle = 3 units

Angle between radius = 60°

Find:

Length of arc CE

Computation:

Length of arc = [θ/360][2πr]

Length of arc CE = [60/360][2(2/7)(3)]

Length of arc CE = [60/360][2(3.14)(3)]

Length of arc CE = [1/6][6(3.14)]

Length of arc CE = 3.14 unit (Approx.)

For each diagram, decide if y is an increase or a decrease of x. Then determine the
percentage.
A
у
B
у

Answers

Answer:

A: Decrease, y is 80% of x

B: Increase, y is 160%of x

Step-by-step explanation:

It sounds like it wants to know what percent Y is of X, so if y was 50% of x, that would mean y was half as much of x. so if x was 10 and y was 5

A:  x is 5 and y is 4  since y is less it is a decrease.  to find the percent do 100*y/x, so in this case that's 100*4/5 =80, so y is 80% of x.  and it makes sense it is less than 100% since x is less than y

B: x=5 and y=8  y is greater than x so it is an increase and will be more than 100%.  100*8/5 = 160 so y is 160% of x
