Which function has the smallest minimum?
A. All three functions have the same minimum
B. f(x)
C. g(x)
D. h(x)

Answers

The minimum value for f(x) is pretty straight-forward. -5+2=-3

We can tell by looking at the graph of g(x) that its minimum is -2

By symmetry the table shows a minimum of 3

So f(x) has the smallest minimum.

Answer:

Step-by-step explanation:

We are given three functions and we have to find which one has the smallest minimum.

I function is

[tex]f(x) = -5sin(2x-\pi) +2[/tex]

Since sine varies from -1 to 1, we get this function has a minimum when sine takes value 1.

Minimum of f(x) =1(-5)+2 =-3

II function is

a graph of parabola with minimum at x=3 and y =-2

III function is shown in tabular form.

From the table we find that minimum is x=1 y=3

Tabulating we have

f(x) (3pi/4, -3)

g(x) (3,-2)

h(x) (1,3)

Smallest is for f(x) with least value of -3

The length of the shadow of a flagpole was found to be 72 feet. the shadow of a 3 foot picket fence in line with the flagpole was 4 feet. what is the height of the flagpole?

Answers

We can solve this problem by simply using ratio and proportion. Let us call the height of the flagpole to be X. Therefore the ratio and proportion would be:

3 ft is to 4 ft and X ft is to 72 ft

3 / 4 = X / 72

X = (3 / 4) * 72

X = 54 ft

The height of the flagpole is 54 ft.

Which of the following is true when probability answer is written in the form of a fraction

Answers

The subject area of probability is actually expressed as a fraction or percentage because it represents a part of a whole. In lay man's term, probability is the scientific study of chance, likeliness and odds of an event happening. For example, you want to find the odds of getting a heads in a toss of the coin. You know that there are 2 possible results: head and tails. So, the probability of getting a head is 1/2 or 50%. Since it is a part of a whole, the probability in fraction should never be an improper fraction. This is the type of fraction in which the numerator is greater than the denominator. This is impossible as a probability because it will never exceed 1.

In probability, a fraction does not need to be simplified but converting to a percentage or decimal can aid in interpretation, with percentages being fractions with a denominator of 100. (First option)

When a probability answer is written in the form of a fraction, it is important to know how to handle the result. Simplifying the fraction is not generally required, especially in Probability Topics, where the focus is on understanding the probability itself rather than the arithmetic of fractions.

However, converting the probability to a percentage is a common practice that can help with interpretation. This is done by writing the value of the percent as a fraction with a denominator of 100 and then simplifying it if possible.

Converting a fraction to a decimal is another common step, which involves dividing the numerator by the denominator. It's also important to note that for rounding answers to probability problems, the convention is to round to four decimal places.

the volume of a gas varies inversely as the pressure upon it. if the volume of the gas is 160 cubic centimeters at a pressure of 108 centimeters find the volume when the pressure is 87 centimeters

Answers

It was stated in the problem that a given volume of a is inversely proportional with the pressure of the system. It means that the as the volume increases, the pressure would decrease and as the volume decreases, the pressure would increase. We would express it as:

V α 1/P

To change it to an equality, we introduce a proportionality constant, k. We do as follows:

V = k/P

So, to determine what is asked, we need to first calculate for the value of k.

V = k/P
At V = 160 m^3 P = 108 cmHg
160 = k / (108)
k = 17280

Thus, at P = 87 cmHg
V = 17280 / 87
V = 198.62 m^3

A phone company offers two monthly plans. Plan A costs $30 plus an additional $0.15 for each minute of calls. Plan B costs $16 plus an additional $0.20 for each minute of calls.
For what amount of calling do the two plans cost the same?
What is the cost when the two plans cost the same?

Answers

Plan A = 30 +0.15x

Plan B = 16 +0.20x

30+0.15x = 16+0.20x

subtract 16 from each side

14 +0.15x = 0.20x

subtract 0.15x from each side

14=0.05x

x = 14/0.05 = 280 minutes

280*0.15 = 42 +30 = $72

280 * 0.20 = 56 +16 = 72

280 minutes and cost $72 each

Lets m = number of minutes calls

Plan A : 30 + 0.15 m
Plan B: 16 + 0.20 m

For what amount of calling do the two plans cost the same?

30 + 0.15m = 16 + 0.20m
0.05m = 14
m = 280

280 minutes of calling, the two plans cost the same

What is the cost when the two plans cost the same?

Plan A: 30 + 0.15 m = 30 + 0.15 (280) = 72

Plan B: 16 + 0.20 m = 16 + 0.20 (280) = 72

answer

The course for the frog hopping race is 59 inches long. Max's frog has jumped 2 feet and 3 inches. How much further does Max's frog need to jump in order to reach the finish line?

Answers

2ft is equal to 24 inches+3 is equal to 27 inches travelled total.
To find what is left subtract 59-27=32 inches left, which is equivalent to 2 ft 8 inches

To find the remaining distance Max's frog needs to jump in the race, convert the initial jump to inches, and subtract it from the total race length.

The frog hopping race's course is 59 inches long. Max's frog has jumped 2 feet and 3 inches. To find out how much further Max's frog needs to jump to reach the finish line, convert 2 feet and 3 inches to inches and subtract it from 59 inches.

The conversion is: 2 feet x 12 inches = 24 inches. Adding 24 + 3 inches gives 27 inches. Subtract 27 inches from 59 inches to find the remaining distance Max's frog needs to jump.

The distance Max's frog still needs to jump is 32 inches.

in the system shown below, what are the coordinates of the solution that lies in quadrant I? x^2-y^2=25, x+y=25

Answers

The given equations in this item are,
x² - y² =25
and
x + y = 25

It can be deduced that the first equation is a difference of two squares and can be factored out as that one shown below.
(x - y)(x + y) = 25

From the second equation, x+y = 25. Substituting this to the equation above,
(x-y)(25) = 25
Hence, x - y = 1

The system of linear equations is,
x + y = 25
x - y = 1
Adding the equations together,
2x = 26
x = 13

The value of y is 12.

Since both x and y are positive values then, this solution lies in the first quadrant.

Find the equation of the circle that has a diameter with endpoints located at (7, 3) and (7, –5).

Answers

Final answer:

The equation of the circle with a diameter between (7, 3) and (7, -5) is (x - 7)² + (y + 1)² = 2².

Explanation:

To find the equation of the circle, we first need to find its center. The center of a circle is the midpoint of its diameter. To find the midpoint of (7, 3) and (7, -5), we can add the x-coordinates and divide by 2 to get 7. For the y-coordinates, we add -5 and 3 and divide by 2 to get -1. So, the center of the circle is (7, -1).

The radius of the circle is half the length of the diameter. The distance between the center of the circle and one of the endpoints of the diameter (7, 3) is the radius. Using the distance formula, the radius is √((7-7)² + (3+1)²) = 2.

Now, we can use the center and radius to write the equation of the circle, which is (x - 7)² + (y + 1)² = 2².

A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed, the angle of depression to the boat is 16°23'. When the boat stops, the angle of depression is 49°29' . The lighthouse is 200 feet tall. How far did the boat travel from when it was first noticed until it stopped? Round your answer to the hundredths place.

Answers

check the picture below.

now, bear in mind that, there are 60minutes in 1 degree, so 23' is just 23/60 degrees or about 0.38 degrees.

and 29' is just 29/60 degrees or about 0.48 degrees.

so 16°23' is about 16.38°, and 49°29' is about 49.48°

[tex]\bf tan(16.38^o)=\cfrac{200}{a+b}\implies a+b=\cfrac{200}{tan(16.38^o)} \\\\\\ \boxed{b=\cfrac{200}{tan(16.38^o)}-a} \\\\\\ tan(49.48^o)=\cfrac{200}{b}\implies \boxed{b=\cfrac{200}{tan(49.48^o)}}\\\\ -------------------------------\\\\ \cfrac{200}{tan(49.48^o)}=\cfrac{200}{tan(16.38^o)}-a\\\\\\a=\cfrac{200}{tan(16.38^o)}-\cfrac{200}{tan(49.48^o)}[/tex]

Choose the graph below that correctly represents the equation 15x − 5y = 30.

will give brainiest to best answer!!

PLEASE HELP!!!

Answers

You didn't give us a picture but I'll help you as best as I can.

First, convert the equation into the form y=mx+b:
15x-5y=30
-5y=-15x+30

Divide both sides by -5.
y=-3x-6

Below is a graph of that equation:

Final answer:

To choose the correct graph that represents the equation 15x - 5y = 30, isolate y, find the slope and y-intercept, and compare to the given graphs.

Explanation:

In order to choose the correct graph that represents the equation 15x - 5y = 30, we need to solve the equation for y.

First, let's isolate y by subtracting 15x from both sides of the equation:

15x - 5y - 15x = 30 - 15x

-5y = -15x + 30

Next, divide both sides of the equation by -5 to find the value of y:

-5y/-5 = (-15x + 30)/-5

y = 3x - 6

Now that we have the equation in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept, we can determine the graph that represents the equation. The slope of the equation is 3, which means that for every 1 unit increase in x, y increases by 3 units. The y-intercept is -6, which means that the graph intersects the y-axis at the point (0, -6).

Based on this information, we can determine that the graph that correctly represents the equation 15x - 5y = 30 is the one where the slope is 3 and it intersects the y-axis at (0, -6).

so... hmm now for a) a decagon is 10 sides, b) pentagon is 5 sides, d) and e) pretty much you can tell how many sides on those already.

Answer:

Step-by-step explanation:

As we know for a regular polygon sum of all interior angles is represented by n A = 180 (n-2)

and sum of all exterior angles is represented by n A' = 360°

Here n represents number of sides of the polygon.

Now we will go for each options given.

(A) Decagon : (Having 10 sides)

(1) 8A = 180 ( 8-2 )

8A = 180 × 6

A = [tex]\frac{1080}{8}[/tex] = 160° ( interior angle )

(2) n A' = 360°

8 A' = 360°

A = 45° ( exterior angle )

(B) Pentagon ( having 5 sides )

(1) 5A = 180 ( 5-2 )

5A = 180 × 3 = 540

A = 108° ( interior angle )

(2) 5A' = 360

A' = 72° (exterior angle )

(C) Dodecagon : ( having 12 sides )

(1) 12A = 180 (12-2)

12 A = 180 × 10 = 1800

A = 150° ( interior angle )

(2) 12 A' = 360

A' = 30° ( exterior angle )

(D) 16-gon ( having 16 sides )

(1) 16 A = 180 ( 16 - 2 )

16A = 180 × 14

16 A = 1520

A = 157.5° ( interior angle )

(2) 16 A' = 360

A' = 22.5°

(E) 25-gon ( having 25 sides )

(1) 25 A = 180 ( 25-2)

25A = 180 (23)

A = 165.6° ( interior angle )

(2) 25A' = 360

A = 14.4° ( exterior angle)
