Answer:

Table C

Step-by-step explanation:

To find the constant of proportionality, you need to divide y by x

Table A has a constant of proportionality of $\frac{1}{3}$ which is 0.3333 repeating

Table B has a constant of proportionality of $\frac{3}{5}$ which is 0.6

Table C has a constant of proportionality of $\frac{3}{10}$  which is 0.3

What is the measure of 0 ?

MrRissso [65]

Answer:

Option A. 4 radians

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

$C=2\pi r$

we have

$r=5\ cm$

substitute

$C=2\pi (5)$

$C=10\pi\ cm$

step 2

Find the measure of angle $\theta$

we know that

The circumference of the circle subtends a central angle of 2π radians

using proportion

Find out the central angle by an arc length of 20 cm

$\frac{10\pi}{2\pi}=\frac{20}{x}\\\\x=2\pi (20)/10\pi\\\\x=4\ radians$

The population of rabbits on an island is growing exponentially. In the year 1990, the population of rabbits was 1200, and by 19

kobusy [5.1K]

Answer:

2023 rabbits

Step-by-step explanation:

The exponential model consists of the following expression:

$y = A \cdot r^{t}$

Where:

$A$ - Initial population.

$r$ - Increase rate.

$t$ - Time

$y$ - Current population.

The initial population and increase rate are, respectively:

$1200 = A \cdot r^{0}$

$A = 1200$

$1700 = 1200 \cdot r^{4}$

$r^{4} = \frac{1700}{1200}$

$r^{4} = \frac{17}{12}$

$r = \sqrt[4]{\frac{17}{12} }$

$r \approx 1.091$

The exponential model that predicts the population of rabbits is:

$y = 1200\cdot 1.091^{t}$

Lastly, the expected population for the year 1996 is:

$y = 1200\cdot 1.091^{6}$

$y\approx 2023.624\,rabbits$

Expand: 4(5x+5) - 3(2x + 4)

aliina [53]

Answer:

14x + 8

Explanation:

⇒ 4(5x+5) - 3(2x + 4)

distribute inside parenthesis

⇒ 4(5x) + 4(5) - 3(2x) - 3(4)

multiply the variables

⇒ 20x + 20 - 6x - 12

collect like terms

⇒ 20x - 6x + 20 - 12

subtract like term

⇒ 14x + 8
