Step-by-step explanation:

Answer:

3

Step-by-step explanation:

[tex]5a = 15\\\frac{5a}{5} = \frac{15}{5} \\a = 3[/tex]

5 * 3 = 15

To simplify the expression (x⁻³ × y² / x⁴ × y⁶) cubed, you need to cube each term in the fraction individually.

To simplify (StartFraction (x⁻³) (y²) Over (x⁴) (y⁶) EndFraction) cubed, you need to cube each term in the fraction individually.

Here is the step-by-step breakdown:

Cube the numerator: x⁻⁹y⁶

Cube the denominator: x¹²y¹⁸

Combine the cubed terms: (x⁻⁹y⁶) / (x¹²y¹⁸)

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   .

Answer:

shrinks/ 2/3

Answer:

The equation that represents the battery charge in Sanchez's phone as a percentage t hours after he left his house is B(t) = 30 - 3*t.

Step-by-step explanation:

The initial state of the battery on Sanchez's phone is 30% so in time t equals zero the battery should be at that value and as time progresses the battery should lose battery charge at a rate of 3% for each hour. We can write this in an equation form by taking the initial state and subtract it by the rate multiplied by the value of time. We have:

B(t) = 30 - 3*t

The equation that represents the battery charge in Sanchez's phone as a percentage t hours after he left his house is B(t) = 30 - 3*t.

Answer:

[tex]A(t)=(0.902)^t \cdot 1500[/tex] [tex][km^2][/tex]

Step-by-step explanation:

In this problem, the initial area of the  forest at time t = 0 is

[tex]A_0 = 1500 km^2[/tex]

After every year, the area of the forest decreases by 9.8%: this means that the area of the forest every year is (100%-9.8%=90.2%) of the area of the previous year.

So for instance, after 1 year, the area is

[tex]A_1 = A_0 \cdot \frac{90.2}{100}=0.902 A_0[/tex]

After 2 years,

[tex]A_2=0.902 A_1 = 0.902(0.902A_0)=(0.902)^2 A_0[/tex]

And so on. So, after t years, the area of the forest will be

[tex]A(t)=(0.902)^t A_0[/tex]

And by substituting the value of A0, we can find an explicit expression:

[tex]A(t)=(0.902)^t \cdot 1500[/tex] [tex][km^2][/tex]

Answer:

Step-by-step explanation:

The roll of nickels forms a cylinder

cylinder area includes the sides and the round areas

round areas  = pi r^2   there is two   so    2 pi r^2

                                                                    = 2 pi (.835/2)^2

and the side area  pi x d x h

                               pi x .835 ( .077 x 40)     (there are 40 nickels in $ 2

Add the areas to get the total ......

To find the total surface area of a $2 roll of nickels, we calculate the surface area of one nickel and then multiply by 40 (the number of nickels in a $2 roll), resulting in an approximate surface area of 47.84 in² when rounded to the nearest hundredth.

To calculate the approximate surface area of a $2 roll of nickels, we must first determine how many nickels are in a $2 roll. Knowing that each nickel is worth 5 cents, a $2 roll would contain 40 nickels ($2.00 / $0.05 = 40). The surface area of a nickel includes the area of the circles on both sides and the area of the edge. The formula for the area of a circle is πr² (where r is the radius) and the formula for the area of the side (cylinder height) is 2πrh (where h is the width).

The diameter of a nickel is 0.835 inches, so the radius is half of that or 0.4175 inches. Using these measurements:

Therefore, the total approximate surface area for a $2 roll of 40 nickels = 40 * 1.196 in² = 47.84 in².

Rounded to the nearest hundredth, the surface area is 47.84 in².

Answer:

33 π

Step-by-step explanation:

Given,

Area of circle = 36 π

Central angle of sector,θ = 11/6 rad

Area of the sector = ?

we know,

A = π r²

36 π = π r²

r = 6

Area of sector

[tex]A = \frac{1}{2} r^2 \theta [/tex]

[tex]A = \frac{1}{2} \times 6^2 \times (\frac{11}{6}\pi)[/tex]

[tex]A = 33\pi \ sqr. units[/tex]

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.

Answer:

80

Step-by-step explanation:

The sides of a triangle always add up to 180. 80+20+?=180

Answer:

C, 80 degrees

Step-by-step explanation:

Together, all of the interior angles in a triangle add up to 180 degrees. Therefore, the missing angle is the two other angles subtracted from 180 degrees. 180-20-80=80 degrees, or answer choice C. Hope this helps!

Answer:

  $2700

Step-by-step explanation:

Using Heron's formula, we can find the area of the triangle to be ...

  A = √(s(s -a)(s -b)(s -c)) . . . . where s=(a+b+c)/2 and a, b, c are the sides

Here, we have ...

  s = (50 +75 +100)/2 = 225/2 = 112.5

  A = √(112.5 · 62.5 · 37.5 · 12.5) ≈ 1815.461 . . . square yards

Then the profit is expected to be ...

  (1815.451 yd²)($1.50/yd²) = $2723.19 ≈ $2700

The farmer expects a profit of about $2700 from that crop.

Answer:

from the looks of it, all you have to do is, for f(x), is plug it in as an exponent. in order (top to bottom), it should be: 64, 2048, 4096, 8192.

g(x) is being squared and then multiplied, so it should be (from top to bottom): 720, 2420, 2880, 3380

C(-3,5;-2) abscissa: -3.5 ordenada -2

D(0,-1) abscisa: 0 ordenada:- 1

Step-by-step explanation:

What we must take into account is that the abscissa is the value of x and the ordinate is the value of y. There is always a number of the (x,y), that is, the abscissa is the first value and the ordinate is the second value, therefore:

Answer:

We need to identify  abscissa and ordenada in each of the pairs given.

For a pair (x, y), x is the abscissa and y is the ordenada.

Answer:

8x squared- 6x+16 is the answer

Answer: the z score is 2.4

Step-by-step explanation:

Since the lengths of the certain species of beetles are normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = length of the beetle species.

µ = mean length

σ = standard deviation

From the information given,

µ = 1.9 centimeters

σ = 0.2 centimeters

For a species with a length of 2.38 centimeters, the z score is

z = (2.38 - 1.9)/0.2

z = 0.48/0.2

z = 2.4

Step-by-step explanation:

You need to work backwards and do the opposite

So, first do subtraction since Melanie added to her collection. SO do the opposite of addition.

17-9=8

Then, since she sold half of her comics, and she is dividing her collect, you multiply 8 with 2.

8 x 2=16

Final answer

Answer:

Yes the information i.e. AT ║ CS and diagonals AS = CT are sufficient to prove that CATS is an isosceles trapezoid.

CATS is an isosceles trapezoid. (Proved)

Step-by-step explanation:

Yes the information i.e. AT ║ CS and diagonals AS = CT are sufficient to prove that CATS is an isosceles trapezoid.

Proof :

Taking Δ CAT and Δ STA,

(i) CT = AS (Given)

(ii) AT is the common side and

(iii) ∠ ACT = ∠ TSA

{Since AT ║ CS and the angles are obtained from the same base AT}

Therefore, by the criteria Side-Side-Angle i.e. SSA, we can say Δ CAT ≅ Δ STA.

Hence, AC = ST {Corresponding sides}

Therefore, CATS is an isosceles trapezoid. (Proved)
