The area of the octagon below is 10,391.9 square millimeters. What is the approximate perimeter of the octagon? Round to the nearest whole number. Mm What is the approximate length of one side of the octagon? Round to the nearest whole number. Mm

Answer:

Let x be the number of mile.

Total cost is no more than 130.

As per the given statement: if the car rental 94 a week plus 12 cent a mile.

12 cent a mile means 12x

then the equation become:

[tex]94 + 12x \leq 130[/tex]

Subtract 94 to both sides we get;

[tex]94 + 12x-94 \leq 130-94[/tex]

Simplify:

[tex]12x \leq 36[/tex]

Divide both sides by 12 we get;

[tex]x \leq 3[/tex]

Therefore, 3 miles she drive  if the car rental 94 a week plus 12 cent a mile.

a) -1 mult. 2 & 2 mult. 2

b) [tex]-a(x+1)^2(x-2)^2[/tex]

c) 4 at least (even degree could be 4, 6, 8, etc)

Step-by-step explanation:

A polynomial graph has several features we look for to determine the equations.

In this graph, there are two real zeros: -1,2

We can write them in intercept or factored form as (x+1) and (x-2).

Because the graph never crosses the x-axis each has an even multiplicity of at least 2.

The graph is facing down and is an upside down W so is negative. [tex]-a(x+1)^2(x-2)^2[/tex]

This means the function has a degree of 4 or higher with the degree being even.

Answer:

130m

Step-by-step explanation:

Let the ocean be the origin (0,0)between the the bird flying and the shark swimming. If the distance between a bird flying and the ocean is 100m and the distance between the ocean above and a shark swimming below the sea is 30 m, the distance between the flying bird and the shark will be calculated by adding the two distances to give;

=(100-0)+(30-0)

= 100+30

= 130m

Note that the ocean serves ad the origin(0,0) therefore the distance between each animal and the sea will be known first and the two values will be added as shown above to get the distance between the two animals.

 The population at the end  of 2017 is 65,550

Step-by-step explanation:

 step 1; find the  population   at the end  of 2016

if 60,000   increases by 15% therefore final % = 100 +15 =115%

Therefore  60,000   = 100%

                         ?      =    115%

by cross multiplication

={ (115 % x 60,000) /100}  =69,000

Step 2:  find the population at the end  of 2017  

if  69,000   decrease by 5% therefore the final% = 100 -5 =95%

Therefore 69000  = 100%

           ?    =  95%

by cross multiplication

= 69000 x 95/100 = 65,550

Answer:

20 pages

Step-by-step explanation:

2 minutes is 1/2 of 4 minutes.

By proportion  number of pages he scans in 2 minutes = 1/2 * 40

= 20 pages

Final answer:

To calculate the number of pages a scanner can scan in 2 minutes, you divide the total pages scanned in 4 minutes by 4 to find the rate per minute, and then multiply by 2. The scanner can scan 20 pages in 2 minutes.

Explanation:

To find out how many pages a scanner can scan in 2 minutes if it can scan 40 pages in 4 minutes, we use proportion or unit rate since the scanning speed is constant. We start by determining how many pages are scanned in one minute. Since 40 pages are scanned in 4 minutes, we divide 40 by 4 to find the scanning speed per minute:

40 pages ÷ 4 minutes = 10 pages per minute.

Now we find out how many pages can be scanned in 2 minutes by multiplying the rate by the number of minutes:

10 pages per minute × 2 minutes = 20 pages.

Therefore, the scanner can scan 20 pages in 2 minutes at the given rate.

Answer:

$6.    

Step-by-step explanation:

Let x be the new price of ticket.

We have been given that a ticket cost $4.80. The new ticket price will be 1.25 times the old price.  

We can represent this information as:

[tex]x=1.25\times 4.80[/tex]  

[tex]x=6[/tex]      

Therefore, the cost of new ticket will be $6.

Final answer:

The new ticket price will be $6.00

Explanation:

Increased Price: The problem states that the new ticket price will be 1.25 times the old price. This means the new price will be 25% higher than the old price.

Calculating the Increase: To calculate the new price, we need to find 1.25 times the old price. Mathematically, this is done by multiplying the old price by 1.25.

Old ticket price: $4.80

Calculation: New ticket price = Old ticket price × 1.25

Calculation: New ticket price = $4.80 × 1.25 = $6.00

Therefore, the new ticket price will be $6.00

Answer:

The equation of this line is y - 7 = 4(x + 3)

Step-by-step explanation:

To find this, start with the base form of point-slope form.

y - y1 = m(x - x1)

Now put the slope in for m and the two coordinates in for (x1, y1).

y - 7 = 4(x + 3)

Final answer:

The equation in Point-Slope form for the given point ( -3,7) and slope 4 is B. y - 7 = 4 ( x + 3 ). (Option B)

Explanation:

The correct equation in Point-Slope form for the given point and slope, where the point is ( -3,7) and the slope is 4, can be written as y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point through which the line passes. Substituting the given values, we obtain y - 7 = 4(x + 3).

Therefore, the correct equation in Point-Slope form is:

B. y - 7 = 4 ( x + 3 )

Answer:

550

Step-by-step explanation:

We can write a proportion to find the total amount using the information given. A proportion is two equivalent ratios set equal to each other. Since we know the population increased to 200% of last year and is 1,100.

[tex]\frac{200}{100}=\frac{1100}{y}[/tex]

We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.

200y=100(1100)

200y=110,000

y=550

There was 550 rabbits last year.

By applying percentages and division, we find that there were 550 rabbits last year, as this year's population of 1,100 rabbits is 200% or twice the amount of last year's.

The rabbit population in a certain area is 200% of last year's population. This year, there are 1,100 rabbits. It means that 1,100 is double the population from last year because 200% is equal to 2 times the original number. To find the population of rabbits last year, we need to take this year's total and divide it by 2. So, 1,100 rabbits divided by 2 equals 550 rabbits. Therefore, last year, the population of rabbits was 550.

Answer:

(1) B. f(x)->0  as x->∞, f(x)->∞  as x->-∞

(2) D. [tex]f(x)= 2^{-x}+5[/tex]

Step-by-step explanation:

[tex]f(x) = b^x[/tex]. Given 0<b<1

'b' is between 0  and 1  so b should be a fraction

'b' is a fraction, so for positive value of x , the value of f(x) cannot be negative.

the graph of f(x) will goes close to 0 but it never cross x  axis

So end behavior is f(x)->0  as x->∞

for negative values of x , the y value increases

So end behavior is f(x)->∞  as x->-∞

(2)  f(x) = 2^x

When graph reflects across y axis, x becomes -x

so [tex]f(x)= 2^{-x}[/tex]

For translating up by 5 units we add 5  at the end

so [tex]f(x)= 2^{-x}+5[/tex]

When 0 < b < 1, the graph of the function f(x) = [tex]b^x[/tex] is decreasing. This means that the values of f(x) will get smaller and smaller as x gets larger and larger.

In the limit as x approaches positive infinity, f(x) will approach zero. On the other hand, in the limit as x approaches negative infinity, f(x) will approach positive infinity.

The correct answer is g(x) = 2*+5.

The function g(x) = 2*+5 reflects the graph of f(x) = 2x across the y-axis and translates it up 5 units.

The reflection across the y-axis is achieved by multiplying the function by -1.

The translation up 5 units is achieved by adding 5 to the function.

The graph of g(x) is also shifted up 5 units.
