Answer:

8x10^4=80,000

8x10^1=80

79,920 times larger!

Step-by-step explanation:

Hope that helps! :)

The values 8 * 10^4 is 1000 times larger than 8 * 10^1

Scientific notations are expressions written in the form A * 10^n

Given the following scientifc notations:

A = 8 x 10^4

B = 8 x 10^1

In order to know how many times larger  is 8 x 10^4 than 8 x 10^1, we will take the ratio of both values as shown;

Ratio =

[tex]\frac{A}{B} = \frac{8 \times 10^4}{8 \times 10^1}\\ \frac{A}{B} = 1 \times 10^{4-1} \\ \frac{A}{B} = 10^3\\ \frac{A}{B} = 1000[/tex]

This shows that the values 8 * 10^4 are 1000 times larger than 8 * 10^1

Answer:

Coordinate

Step-by-step explanation:

It is a coordinate because with slope you would need at least two ordered pairs

Answer:

A coordinate.

Step-by-step explanation:

A coordinate takes the form of ( x , y ), in which x is the horizontal, while y is the vertical.

In this case, (6 ,0) is the given coordinate, in which it displaces +6 to the right of the (0 , 0).

Given:

The radii of circles are 14 cm and 7 cm.

To find:

The area of the shaded region.

Solution:

Area of a circle is

[tex]Area=\pi r^2[/tex]

From the given figure, it is clear that

Area of shaded region = Area of larger circle - Area of smaller circle

                                      = [tex]\pi (14)^2-\pi (7)^2[/tex]

                                      = [tex]\dfrac{22}{7}\times 14\times 14-\dfrac{22}{7}\times 7\times 7[/tex]

                                      = [tex]616-154[/tex]

                                      = [tex]462[/tex]

Therefore, the area of the shaded region is 462 sq. cm.

Answer:

25c^2-30cd

Step-by-step explanation:

The product of expression is,

⇒ 5c (5c - 6d)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ (5c - 3d)² - 9d²

Now, We can write the expression in form of product as;

⇒ (5c - 3d)² - 9d²

⇒ (5c - 3d)² - (3d)²

⇒ (5c - 3d - 3d) (5c - 3d + 3d)

⇒ (5c - 6d) (5c)

⇒ 5c (5c - 6d)

Thus, The product of expression is,

⇒ 5c (5c - 6d)

Answer: A)y = 358,000(2)t

Step-by-step explanation:

since the population is 358,000 and it's decreasing by 2%, then that means that it would 2, hence it would not be b, c, or d

bam hope this helped (if it did mark brainliest)

Answer:

Part A: C) y = 358,000(0.98)^t

Part B: about 323604 people

Step-by-step explanation:

This problem would represent an exponential function, which involves a constant multiplicative rate. I believe you could view it in the form of y = (initial population)(rate)^t.

In this case, since it is decreasing annually by 2%, you could view the multiplicative rate as 98% (0.98 in decimal form), since 98% would be remaining each year you deduct 2%.

So, it would be y = 358,000(0.98)^t for Part A.

For Part B, simply plug in 5 for t, since t is being measured in years:

358,000(0.98)^5 = 323603.645254 ≈ 323604 people

The graph and therefore, the sinusoidal function equation is a wave function graph and equation

The formula of the sinusoidal function can be written as follows;

[tex]y = \mathbf{5 \cdot sin\left (\dfrac{1}{2} \cdot \left (x + \dfrac{\pi}{2} \right)\right)}[/tex]

The process of deriving the equation of the sinusoidal function is as follows:

The given parameters of the sinusoidal function are;

The coordinate of the maximum point = (0, 5)

The coordinate of the minimum point = (2·π, -5)

Method:

The general form of the sinusoidal function is y = A·sin(B·(x - h)) + k

From the given coordinates of points on the graph of the sinusoidal wave, the values of A, B, h, and k can be calculated as follows

Solution:

y = A·sin(B·(x - h)) + k

Where;

A = Amplitude = (Maximum y-value - Minimum y-value)/2

∴ A = (5 - (-5))/2 = 5

A = 5

The period, T = 2·π/B = The time to complete a cycle = Time from maximum y-value to another maximum y-value

∴  The period, T  = 2 × (The x-value at maximum y-value - The x-value at minimum y-value)

T = 2 × (0 - 2·π) = -4·π

Given that the period, T represent a scalar quantity, we have T = 4·π

∴ T = 4·π = 2·π/B

B = 2·π/4·π = 1/2

B = 1/2

From the given coordinates, at x = 0, f(x) is maximum, therefore, sin(B·(x - h)) = 1, which gives;

B·(x - h) = π/2

(1/2)·(0 - h) = π/2

h = -π/2

The vertical shift, k =  (Maximum y-value + Minimum y-value)/2

∴ k = (5 + (-5))/2 = 0, there is no vertical shift

Therefore;

The equation of the sinusoidal function is y = 5·sin(1/2·(x - (-π/2)) + 0, from which the equation can be presented as follows;

[tex]y = \mathbf{ 5 \cdot sin\left (\dfrac{1}{2} \cdot \left (x + \dfrac{\pi}{2} \right)\right)}[/tex]

because it is

When x = -3;

w = -5(-3) - 1

w = 15 - 1

w = 14

When x = 0;

w = -5(0) - 1

w = 0 - 1
