Answer:
n >= -1/4
Step-by-step explanation:
Divide both sides by the same factor, and flip the relation because the factor is negative
-28n/-28 >= 7/-28
Simplify,
Cancel terms that are in both the numerator and denominator.
n >= 7/-28
Divide the numbers.
n >= 7/-28 = n >= -1/4
The answer is n >= -1/4

A town has a population of 4.11 x 104 and shrinks at a rate of 9.6% every year.
Which equation represents the town's population after 4 years?
Answers
Answer:
59304
Step-by-step explanation:
4.11x 10⁴=41100, 9.6 =( 1+9.6/100)=1.096
x(n)−population after n years
x(n)=x(0)×1.096^n=41100x1.096^n
x(4)=41100×1.096⁴=59304.007
= 59304
An equation represents the town's population after 4 years is [tex]x(4)=4.11\times10^4(1+\frac{9.6}{100})^4[/tex].
Given that, a town has a population of [tex]4.11\times10^4[/tex] and shrinks at a rate of 9.6% every year.
What is population growth and population decrease formula?If a constant rate of growth be R% per annum, then population after n years = [tex]P(1+\frac{R}{100} )^n[/tex]
Now,
[tex]x(4)=4.11\times10^4(1+\frac{9.6}{100})^4[/tex]
⇒ [tex]x(4)=4.11\times10^4(1+0.096)^4[/tex]
⇒ [tex]x(4)=41100\times(1.096)^4[/tex]
⇒ x(n)=41100×1.443
⇒ x(n)=59307.3
Therefore, an equation represents the town's population after 4 years is [tex]x(4)=4.11\times10^4(1+\frac{9.6}{100})^4[/tex].

no
Step-by-step explanation:
(- 3)² = - 3 × - 3 = 9 ≠ -9
Answer:
no , see below
Step-by-step explanation:
when you raise a number to a power, you multiply the number by itself the amount of times the power is. so if (-3) has a power of 2 , we multiply -3 by itself twice.
so we get -3 × -3
a negative times a negative is a positive
so -3 × -3 = 9 , not -9

-7/25
7/25
4/5
Answers
Answer:
7/25
Step-by-step explanation:
Let [tex]\theta= \arcsin(\frac{3}{5})[/tex] so we have [tex]x=\cos(2\theta)[/tex]
As [tex]\cos(2\theta)=\cos^2\theta-\sin^2\theta[/tex], we'll have [tex]\cos[2\arcsin(\frac{3}{5})]=\bigr[\cos(\arcsin(\frac{3}{5}))\bigr]^2-\bigr[(\sin(\arcsin(\frac{3}{5}))\bigr]^2[/tex]
To determine [tex]\cos(\arcsin(\frac{3}{5}))[/tex], construct a right triangle with an opposite side of 3 and a hypotenuse of 5. This is because since [tex]\theta=\arcsin(\frac{3}{5})[/tex], then [tex]\sin\theta=\frac{3}{5}=\frac{\text{Opposite}}{\text{Hypotenuse}}[/tex]. If you recognize the Pythagorean Triple 3-4-5, you can figure out that the adjacent side is 4, and thus, [tex]\cos\theta=\frac{4}{5}=\frac{\text{Adjacent}}{\text{Hypotenuse}}[/tex]. This means that [tex]\cos(\arcsin(\frac{3}{5}))=\frac{4}{5}[/tex].
Hence, [tex]\cos[2\arcsin(\frac{3}{5})]=(\frac{4}{5})^2-(\frac{3}{5})^2=\frac{16}{25}-\frac{9}{25}=\frac{7}{25}[/tex]

b. Describe what this ratio tells you.
Answers
The location with the greatest amount of rainfall is Beaumont, while the location with the least amount is El Paso.
How to identify the place with the greatest and least amount of rainfall?The first step is to make sure to use the same units. Due to this, let's convert everything to meters.
Austin = 0.8687 mBeaumont = 1.534 mGalveston = 1.095 mEl Paso = 0.2464 mDel Rio = 0.4953 mSouth Padre= 0.655mBased on this, Beaumont has the greatest amount of rainfall and El Paso has the lowest amount of rainfall.
How are the two places related?The ratio for these places are 1.5 to 0.2 or 1.5/ 2 = 0.7. This ratio implies that there is a difference of 0.7 meters in the amount of rainfall in these places.

add the numbers 197,203 and 423 in two ways fast
Answers
Answer:
823
Method 1
Break the three numbers into hundreds, tens and units, then add these separately (starting with the units)
197 = 1 hundred, 9 tens, 7 units
203 = 2 hundreds, 0 tens, 3 units
423 = 4 hundreds, 2 tens, 3 units
Units: 7 + 3 + 3 = 13
Tens: 9 + 2 = 11 tens = 110
Hundreds: 1 + 2 + 4 = 7 hundreds = 700
Add these together: 700 + 110 + 13 = 823
Method 2
First add 203 to 197:
Borrow the 3 from 203 and add it to 197: 197 + 3 = 200
Add the remaining 200: 200 + 200 = 400
Now add 423 to 400: 400 + 423 = 823
⇒ 203 + 197 + 423 = (203 + 197) + 423
= 400 + 423
= 823
197
203
423
——
823
Method two:
Add the hundreds first:
100+200+400=700
Then add the tens:
700+90+20=810
Then add the 1s:
810+7+3+3=823

Which trigonometric function does the graph below represent?
Answers
Answer:
(d) 2sin(2θ +π/4) -1
Step-by-step explanation:
The graphed function has a midline of -1 (eliminates choice A). It will be a cosine function shifted right π/8 units, or a sine function shifted left π/8 units.
__
The shift is accomplished by replacing θ with (θ -π/8) in the sine function, or (θ +π/8) in the cosine function. That means, we're looking for an expression that is either of ...
2(cos(2(θ-π/8)) -1 = 2cos(2θ -π/4) -1 . . . . . no match
or
2(sin(2(θ+π/8)) -1 = 2sin(2θ +π/4) -1 . . . . . matches choice D
_____
Additional comment
In the form ...
g(x) = K·f(C(x -A)) +B
the factor K is a vertical stretch factor, C is a horizontal compression factor, A is a right shift, and B is an up shift. In this function, we have its amplitude stretched by a factor of 2, a down shift of 1 unit, and a horizontal shift of π/8. The horizontal compression factor is 2.
__
The amount of horizontal shift for the cosine function is found at the peak nearest the y-axis. The amount of horizontal shift for the sine function is found at the upward midline crossing nearest the y-axis.
