You must complete the  sentence about the yearly rate of change of the bear population, telling whether it grows or shrinks and by what factor.

Thus, the goal is to interpret the rate of change in an exponential model.

The exponential model is:

       [tex]N(t)=2187\cdot \bigg(\dfrac{2}{3}\bigg)^t[/tex]

Let's analyze that function.

When t = 0, (2/3)⁰ = 1 and N(0) = 2,187 × 1 = 2,187

Thus, the population of bears starts with 2,187 individuals.

For t = 1, the population will be N(1) = 2,187 × (2/3).

For t = 2, the population will be N(2) = 2,187 × (2/3)²

And so on, every year the population of bears is multiplied by a factor of 2/3.

Since, 2/3 is less than 1, every year the population will be decreasing (decaying), by a factor of 2/3.

Thus, the answer, i.e. the complete sentence, is:

Every year, the bear population    shrinks    by a factor of    2/3   .

sin ( 2π(270)*t )

Step-by-step explanation:

Solution:-

- The frequency of the hum is denoted as k = 270 Hz.

- The displacement of the hum is modeled by a sinusoidal function.

- The trigonometric modelling of frequency generating systems is given in the following general form:

                               sin ( w*t ) + c

- Where,

              A: The amplitude of displacement e

              w: The angular speed of the hum

              c : The initial condition of displacement.

- Here, we will assume A = 1 and c = 0. The hum starts from time t = 0 seconds.

- The angular speed is the unit of speed that denotes the number of cycles in radians are undergone by the frequency generator device/person in unti time t.

- The angular speed is given by the following relation:

                             w = 2πk

                             w = 2π(270).

- The general model of the hum would be:

                             sin ( 2π(270)*t )

Answer:

a) v=6

b) s= u^2 - v^2 : -2a

Step-by-step explanation:

v^2=u^2+2as

u=12, a=-6, s=9

a)

(12)^2= 12 * 12= 144

v^2=u^2+2as

v^2=(12)^2+ 2*(-6)*9

v^2=144+(-12)*9

v^2=144+(-108)

v^2=36

v=6

b)

v^2=u^2+2as

-2as=u^2 - v^2

s= u^2 - v^2 : -2a

check for s

s= 144 - 36 : -2(-6)

s= 108 : 12

s=9 (equal vs the given)

Answer:

Y = 45*p(y) / (1 - p(y))    if I knew what p(y) is, we can find how many yellow marbles there are.   p(y) = probability of choosing yellow.

Step-by-step explanation:

Total marbles =  35 + 10 + yellow

If probability of choosing yellow =p(y) = yellow/Total

p(y) =  Y/(35 + 10 + Y)

Solve for Y,

p(y)*(35 + 10 + Y) = Y

45*p(y) + p(y)*Y = Y

45*p(y) = Y - p(y)*Y

Y = 45*p(y) / (1 - p(y))

To find the number of yellow marbles in the bag, set up an equation using the given probabilities. Simplify the equation and solve for the total number of marbles. Finally, substitute the value of  into the equation to determine the number of yellow marbles.

To solve this problem, we need to find the number of yellow marbles in the bag. Given that there are 35 blue marbles and 10 red marbles, we can subtract these two numbers from the total number of marbles to find the number of yellow marbles. Let's denote the number of yellow marbles as 'y'. We can set up the equation: 35 + 10 + y = total number of marbles. Since the probability of selecting a yellow marble is , we know that the ratio of yellow marbles to the total number of marbles is . This can be written as: y/total number of marbles = . Now, we can solve for 'y'.

By cross multiplying the ratio equation, we have: y = total number of marbles * . Now we can substitute this value of 'y' in the first equation: 35 + 10 + (total number of marbles * ) = total number of marbles. Simplifying this equation, we find: 45 + (total number of marbles * ) = total number of marbles. Rearranging the equation, we have: (total number of marbles * ) - total number of marbles = -45. Factoring out 'total number of marbles' from the left side, we get: total number of marbles * ( - 1) = -45. Dividing both sides of the equation by ( - 1), we find: total number of marbles = 45 / ( - ). Plugging in the value of , we can evaluate the expression: total number of marbles = 45 / ( - ) = - . Therefore, there are - yellow marbles in the bag.

The question is:

A cake recipe calls for 550 grams of flour. About how many pounds of flour do you​ need? Use the conversion factors (1 ounce)/(28.4 grams) and (1 pound)/(16 ounces).

Answer:

About 1.2 pounds of flour is needed.

Step-by-step explanation:

Given that the cake recipe calls for 550 grams, we want to determine about how many pounds of flour we need.

This simply means we want to convert 550 grams to pounds.

First, we were given (1 ounce)/(28.4 grams)

This implies that

1/28.4 = x/550 ..............................(1)

Where x is 550 grams in ounce.

Solving (1)

28.4x = 550

=> x = 550/28.4

≈ 19.3662

That is 550 grams is equal to 19.3662 ounce

Next, we are given the ratio (1 pound)/(16 ounce). We then convert 19.3662 ounce to pound

Let y be 19.3662 ounce in pound

=> 1/16 = y/19.3662

16y = 19.3662

y = 19.3662/16

≈ 1.2

That is 19.3662 ounce is equal to 1.2 pounds.

Therefore, 550 grams is equal to 1.2 pounds, and it is the amount of flour needed.

You would need approximately 1.210 pounds of flour for the cake recipe.

To convert grams to pounds, we can use the conversion factor:

1 pound = 16 ounces

And we also have the conversion factor:

1 ounce = 28.4 grams

First, we'll convert grams to ounces, and then ounces to pounds.

Given that the recipe calls for 550 grams of flour, let's calculate the amount in pounds.

Step 1: Convert grams to ounces.

550 grams x (1 ounce / 28.4 grams) = 19.366 ounces

Step 2: Convert ounces to pounds.

19.366 ounces x (1 pound / 16 ounces) = 1.210 pounds

Therefore, you would need approximately 1.210 pounds of flour for the cake recipe.

(5.5,5)

Step-by-step explanation:

Answer:

The coordinate of the midpoint is (5.5,5)

Step-by-step explanation:

To find the midpoint between two points, find the average of the x coordinates and the midpoint of the y coordinates.

x=(8+3)/2

x=11/2

x=5.5

y=(2+8)/2

y=10/2

y=5

The coordinate of the midpoint is (5.5,5)

Given:

The circle has a diameter of 30 cm and a chord of 10 cm is drawn.

Radius of the circle = 15 cm

Half of the chord = 5 cm

We need to determine the distance of chord from the center of the circle.

Distance of chord from the center of the circle:

Let us use the Pythagorean theorem, to find the distance between the center and the chord.

Let d denote the distance between the center and the chord of the circle.

Thus, we get;

[tex]15^2=d^2+5^2[/tex]

[tex]225=d^2+25[/tex]

[tex]200=d^2[/tex]

Taking square root on both sides, we get;

[tex]14.14=d[/tex]

Thus, the distance between the center and the chord of the circle is 14.14 cm.

Hence, Option A is the correct answer.

The chord is 14.14 cm far from the center of circle.

First option is correct.

The perpendicular drawn from center to the chord, is always divide the chord into two equal parts.

Radius of circle =  d/2 = 30/2 = 15 cm

A diagram is attached below, in which distance between center and chord is represented by x .

applying Pythagoras theorem

                  [tex]x=\sqrt{(15)^{2} -5^{2} }=\sqrt{225-25}=\sqrt{200} =14.14 cm[/tex]

Thus, the chord is 14.14 cm far from the center of circle.

Answer:

The probability that a point chosen at random will be in the shaded region is 0.25

Step-by-step explanation:

We have been given a small shaded circle inside a larger un-shaded circle. This is shown in the image attached below.

The area of smaller circle is 78.5 squares inches and the area of larger circle is 314 square inches. We have to find the probability that a point chosen at random will be in the shaded region.

Probability is defined as the ratio of Favorable outcome to the Total outcomes. In this case the favorable outcome is that the point should be inside the shaded region i.e. in an Area of 78.5 square inches. And the total outcome is that the point can be anywhere inside the larger circle i.e. within an Area of 314 square inches. Thus the probability that a point chosen at random will be inside the shaded region will be:

[tex]Probability = \frac{\text{Favorable Outcome}}{\text{Total Outcome}} \\\\ = \frac{78.5}{314}\\\\=0.25[/tex]

Thus, the the probability that a point chosen at random will be in the shaded region is 0.25. This means there is a 25% chance that a randomly chosen point will be inside the shaded region.

The Number of Spearmint gum are 27 pieces

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

Let the total number of peppermint gum and spearmint gum in the container is X

Ratio of peppermint gum to spearmint gum=  2 : 3.

Total ratio = 2+ 3=5

we are given that peppermint gum are 18 pieces , so total number of gums  will be calculated as;

Ratio of peppermint/ Total ratio x Total number of gums = Number of peppermint;

2/5 x X= 18

X=(18X 5) / 2 = 45

X=  Total number of gums = 45

Ratio of spearmint/ Total ratio x Total number of gums = Number of spearmint;

3/5 x 45= 27

Therefore Number of Spearmint gum are 27 pieces
