Answer:

D. (x^3 - 10)(x^2 + 10x^3 + 100).

Step-by-step explanation:

Using  the identity a^3 - b^3 = (a - b)(a^2  + ab + b^2):

We have  x^9-1000 :

- here a = x^3 and b = 10 so:

x^9-1000 = (x^3 - 10)(x^2 + 10x^3 + 100)

An octagon is a polygon with 8 sides and angles. The two equal angles are 140 degrees each

An octagon is a polygon with 8 sides and angles

The formula for calculating the sum of interior angle of a regular polygon is expressed as:

S = (n-2) * 180

If the sum of six interior angles of a regular octagon is 800 the other two angles are equal, then;

800 + 2x = (8-2)*180

800 + 2x = 1080
2x = 1080 - 800
2x = 280
x = 140

The two equal angles are 140 degrees each

c) 0.025

d) [tex]f(x)=2950000(0.975)^x[/tex]

e) 2,409,123

Step-by-step explanation:

Part (a)

Exponential DECAY, since the population was decreasing annually.

Part (b)

Initial amount = 2,950,000 people (in the year 2000)

Part (c)

Decay factor = 2.5% = 0.025 (in decimal form)

Part (d)

General form of exponential decay function:

[tex]f(x)=a(1-r)^x[/tex]

where:

Given:

[tex]\implies f(x)=2950000(1-0.025)^x[/tex]

Step-by-step explanation:

(a) When measuring distance like running you measure it in minutes and seconds

(b) When finding the average of a population you have to pick randomly and to get the best results you time them youself

Randomly pick 55 students to run a lap around the track and measure their times.

Answer:

16

Step-by-step explanation:

The figure shown is a trapezoid

Area of a trapezoid = 1/2(bottom base length + top base length) × height

Bottom base length = 7 units

Top base length = 1 unit

Height = 4 units

So area = 1/2 ( 7 + 1 ) × 4

==> add 7 and 1

Area = 1/2 (8) × 4

==> multiply 1/2 and 8

Area = 4 × 4

==> multiply 4 and 4

Area = 16

Ans: The measure of exterior angle i.e angle A is -52⁰.

You meant to say that the measure of an angle A is on exterior angle so let me elaborate it you clearly,

Answer:

(x+6)^2+3

Step-by-step explanation:

translate 6 left

left is negative

so (x+6)^2. it is + because the x goes in the opposite direction causing (x-6)^2 to go right

and 3 units up so add x by 3 to get (x+6)^2+3

Answer:

g(x) = (x + 6)² + 3

Step-by-step explanation:

To move horizontally replace each x with (x ± c)

if you move it to the right, you need x - c

if you move it to the left , you need x + c

Since we are moving to the left 6, we will have: g(x) = x² + 6

To move up or down, add or subtract the constant equal to the units moved, so to move it up 3 would give us:

g(x) = (x + 6)² + 3

The sampling strategy she use was a quota.

Quotas are meant to establish boundaries on the number of specific goods that are allowed to be lawfully imported into the country throughout a distinct period of time. In that, quotas are similar embargoes, except quotas don´t have explicit political purposes as embargoes do.

A Fixed quota would be a maximum amount not to be surpassed, while a tariff rate surcharge allows it, but with a higher duty.

If  each point costs $1000.00. how long would it take to break even by buying is:9 years.

First step

Monthly savings=$958-$948.75

Monthly savings=$9.25

Second step

Time=(Cost of points/Mothly savings)/ 12 months

Time=($1,000/$9.25)/12 months

Time=108/12 months

Time=9 years

Therefore how long would it take to break even by buying is:9 years.

Answer:

Step-by-step explanation:

In order to solve this, you must use the distributive property.

[tex]\sf{\dfrac{4\left(5t+1\right)}{5}}[/tex]

Distributive property:

⇒ A(B+C)=AB+AC

⇒ 4(5t+1)

Multiply by expand.

4*5t=20t

4*1=4

Rewrite the problem down.

20t+4

20t+4/5

[tex]\text{FRACTION RULES: }\\\\\\\Longrightarrow: \sf{\dfrac{A\pm \:B}{C}=\dfrac{A}{C}\pm \dfrac{A}{C}}[/tex]

[tex]\Longrightarrow: \sf{\dfrac{20t+4}{5}=\dfrac{20t}{5}+\dfrac{4}{5}}[/tex]

You have to divide the numbers from left to right.

⇒ 20/5=4

[tex]\Longrightarrow: \boxed{\sf{4t+\dfrac{4}{5} }}[/tex]

Answer:

If 73% of the students surveyed said their favorite color was purple,  1,000 students were surveyed in total.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

Let the total number of persons surveyed be x. However, the question tells us that 350 respondents, or 35% of this x, make up the total.

Hence, mathematically, we have;

73% of x = 219

(73/100) × x = 219

73x = 100×219

73x = 219,000

x = 219,000/219

x = 1,000 students

Thus, if 73% of the students surveyed said their favorite color was purple, 1,000 students were surveyed in total.
