The diameter of a circle is 19 in. Find its circumference in terms of \piπ.

Answer:

The equations that represent an exponential decay are;

A; [y = (0.1)ˣ]

B; [y = 2·(0.3)ˣ]

Step-by-step explanation:

An exponential decay is given by the following formula;

y = a·bˣ

Where;

b < 1

For option A, we have; [y = (0.1)ˣ]

Here; a = 1, b = 0.1 < 1, therefore, the function represents an exponential decay

For option B, we have; [y = 2·(0.3)ˣ]

Here; a = 2, b = 0.3 < 1, therefore, the function represents an exponential decay

For option C, we have; [tex]\left[y = \left(\dfrac{4}{3} \right)^x\right][/tex]

Here; a = 1, b = [tex]\dfrac{4}{3} \right) > 1[/tex], therefore, the function does not represent an exponential decay

For option D, we have; [tex]\left[y = \left(\dfrac{7}{5} \right)^x\right][/tex]

Here; a = 1, b = [tex]\dfrac{7}{5} \right) > 1[/tex], therefore, the function does not represent an exponential decay

Answer:

409 = 223 + z

z = 186

Step-by-step explanation:

We know Tyler is 223 - z or z + 223

409 = 223 + z

409 = z + 223

409 - 223 = z + 223 - 223

186 = z + 223 - 223

z = 186

Answer: The slope of a perpendicular line will be m = 3/2. To find the perpendicular gradient take the negative inverse of the original gradient.

Step-by-step explanation:

The slope of a perpendicular line will be m = 3/2. To find the perpendicular gradient take the negative inverse of the original gradient.

By 'negative inverse' I mean change the sign and switch the numerator and denominator (the top and bottom of the fraction).

The original gradient there is m = - 2/3. Remember the line equation: y = mx + c.

To gain the perpendicular gradient change the - to +, move the 3 to the top and the 2 to the bottom. Now m = + 3 / 2 = 3/2

Answer:

x= −1 /2 y+4

Step-by-step explanation:

Let's solve for x.

2x+y=2(6−2)

Step 1: Add -y to both sides.

2x+y+−y=8+−y

2x=−y+8

Step 2: Divide both sides by 2.

2x /2= −y+8 /2 x= −1 /2 y+4

Answer: C.Neither; the ratios are equivalent

Step-by-step explanation:

Kira spent 15 hours watching T.V and 12 hours reading. The ratio of time spent watching T.V. to time spent reading will be:

= 15/12

= 5/4

= 5:4

Charlie spent 20 hours watching T.V. and 16 hours reading. The ratio of time spent watching T.V. to time spent reading will be:

= 20/16

= 5/4

= 5:4

Therefore, they have equivalent ratio

Answer:

-45x - 18

Step-by-step explanation:

distributive property

Answer:

x = 18/45 (or, in a decimal, 0.4). Someone correct me if I'm wrong. :)

Step-by-step explanation:

We have to use the distributive property here. That means that you multiply -5x by 9 and -2 by 9. So...

9*-5x = -45x

9*-2 = -18

-45x = -18

Now, divide both sides by 45...

-45x/45 = -18/45

x = 18/45 should be the answer.
