[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].

Answer:

Angle 3 is 49 degrees

=============================

Explanation:

Angle 1 is 50 degrees and angle 2 is 48 degrees. Added up, they total to 98 degrees. This is angle DEF.

Angle DEF is congruent to angle ABC because they are alternate exterior angles and because lines m and n are parallel

We are told that angle ABC is bisected (aka cut in half) because of line s; which means that the angles labeled "4" and "5" are exactly half that of angle ABC = 98 degrees

Therefore, angle 4 is 98/2 = 49 degrees and so is angle 3 (due to angles 3 and 4 being vertical angles; angle 3 = angle 4)

Answer:

Option C is correct.

288 degree measure could he have rotated the pentagon so that is mapped onto itself

Step-by-step explanation:

Given:  Patrik rotated the pentagon about its center.

A Rotational symmetry of a regular polygon is based on the number of vertices it has.

If the Pentagon figure is rotated [tex]360^{\circ}[/tex] about its center, each vertex lands exactly on the top of where it started.

Since you have 5 vertices, so your starting vertex can land in 5 different starting places and still come up with the same figure.

So if you take [tex]\frac{360}{5} = 72^{\circ}[/tex] rotations to each consecutive vertex.

⇒a rotation of 72 degree, 144 degree, 216 degree, 288 degree and 360 degree will result in the same figure.

Therefore, 288 degree measure could he have rotated the pentagon so that is mapped onto itself.

Whole numbers are 1 and 2

Step-by-step explanation:

Given that a number 5 and we use the square root of 5.

We are to find two whole numbers that falls between square root of 5.

We know that whole numbers are 0,1,2.....

We know that square root of 5 is irrational approximately equal to 2.236.

Consider square root of 5.

Since square root of any number always has two solutions the solutions are

-[tex]\sqrt{5}[/tex] and [tex]\sqrt{5}[/tex]

We have to find two whole numbers lying between these values.

We see that  0, 1,2 are the whole numbers lying between these two values.

Let us select any two of them from these two.

Say 1,2

Then answer is 1,2.

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:

(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.

Because a triangle must have two equal sides

Final answer:

The sets of measurements that could be the side lengths of a triangle are c (9 cm, 4 cm, 4 cm) and d (7 cm, 10 cm, 8 cm), as they both satisfy the Triangle Inequality Theorem.

Explanation:

The question asks which set of measurements could be the side lengths of a triangle. To determine if three lengths can form a triangle, we can use the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides must be greater than the length of the third side. Let's analyze each option:

Therefore, options c (9 cm, 4 cm, 4 cm) and d (7 cm, 10 cm, 8 cm) could be the side lengths of a triangle.

The compound interest for 5 year is $3868.7.

Interest accrued on both the principal sum of money and the interest already earned.

The formula for compound interest is p(1+r/100)ⁿ - p

Where p is principal amount, r is rate and n is time.

Given that,

Principal = $20000,

Time = 5 years,

And rate of interest = 18/5 %

To find compound interest, use formula,

Compound interest =  p(1+r/100)ⁿ - p

Compound interest = 20000(1+18/(5×100))⁵-20000

Compound interest = 23868.7 - 20000

                                 = 3868.7

The compound interest for 5 years is $3868.7.

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: 3 1/4 tons = 6500 tons

Step-by-step explanation:

3 tons is 6000 since 3 * 2000 = 6000

1/4 would be 25% of 2000 which would be 500

because if you take 500 four times it will be 2000

So here you go bud.

3 1/4 tons in pounds.

if 2000 pounds are 1 ton multiply 2000 to 3 tons.

You get 6000.

Then you move on to 1/4.

2000 divided by 4 is 500.

500 is your 1/4.

So 6500 is your answer.

Answer:

Anya rode at 8.5 miles per hour.

Step-by-step explanation:

We have been given that Taylor and Anya live 63 miles apart. One day they left their houses at 8 am and met at 11 am riding toward each other. Taylor rode at 12.5 miles per hour.

We can see that Taylor and Anya met after 3 hours as 11-8=3. This means that both rode their cycles for 3 hours.

Let us find distance covered by Taylor.

[tex]\text{Distance}=\text{Speed*Time}[/tex]

[tex]\text{Distance covered by Taylor}=12.5\frac{\text{Miles}}{\text{hour}}*3\text{ hours}}[/tex]

[tex]\text{Distance covered by Taylor}=12.5*3\text{ Miles}[/tex]

[tex]\text{Distance covered by Taylor}=37.5\text{ Miles}[/tex]

Therefore, Taylor covered 37.5 miles in 3 hours.

Let us find distance covered by Anya in 3 hours by subtracting distance covered by Taylor from total distance of 63 miles.

[tex]\text{Distance covered by Anya in 3 hours}=(63-37.5)\text{ Miles}[/tex]

[tex]\text{Distance covered by Anya in 3 hours}=25.5\text{ Miles}[/tex]

Now let us find speed at which Anya rode bike.

[tex]\text{Speed}=\frac{\text{Distance}}{\text{Time}}[/tex]

[tex]\text{Speed at which Anya rode the bike}=\frac{25.5\text{ Miles}}{3\text{ Hour}}[/tex]

[tex]\text{Speed at which Anya rode the bike}=8.5\frac{\text{ Miles}}{\text{ Hour}}[/tex]

Therefore, Anya rode the bike at the speed of 8.5 miles per hour.
