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:

[tex]h>1600[/tex]

Step-by-step explanation:

We have been given that Matt is climbing a mountain. When his elevation is higher than 1600 meters, breathing is difficult for Matt.

We are asked to write an inequality that describes h, the elevation at which breathing is difficult for Matt.

We know when elevation (h) will be higher than 1600 meters Matt will face difficulty in breathing. We can represent this situation as:

[tex]h>1600[/tex]

Therefore, inequality representing the elevation at which breathing is difficult for Matt will be [tex]h>1600[/tex].

Step-by-step explanation:

First of all, we will make a diagram to demonstrate the given scenario as shown in the attached picture.

Now we will use similar triangles to set the ratios as shown below to figure out the height of the building.

[tex]\frac{x}{130} =\frac{5.5}{8}[/tex]

Now we will solve for x from this equation by cross multiplying.

[tex]8x=130\cdot5.5[/tex]

[tex]8x=715[/tex]

[tex]x=89.375[/tex]

Therefore, height of the building is approximately 89 feet.

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.

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.
