(9,40,41) is a Pythagorean Triple, farther down the list than teachers usually venture.

Answer: D. 41 cm

There's a subset of Pythagorean Triples where the long leg is one less than the hypotenuse,

a^2+b^2 = (b+1)^2

a^2 + b^2 = b^2 + 2b +1

a^2=2b+1

So we get one for every odd number, since the square of an odd number is odd and the square of an even number is even.

b = (a^2 - 1)/2

a=3, b=(3^2-1)/2=4, c=b+1=5

a=5, b=(5^2-1)/2 =12, c = 13

a=7, b=24, c=25

a=9, b=40, c=41

a=11, b=60, c=61

a=13, b=84, c=85

It's good to be able to recognize Pythagorean Triples when we see them.  

Otherwise we'd have to work the calculator:

√(9² + 40²) = √1681 = 41

f(4)= 16.

The answer is **C) 16**.

Here's how to evaluate the piecewise function f(4):

1. **Identify the appropriate rule:**

  - Since 4 is greater than 2 (4 > 2), we'll use the second rule of the function: f(x) = 5x - 4.

2. **Substitute x = 4:**

  - f(4) = 5(4) - 4

3. **Simplify:**

  - f(4) = 20 - 4 = 16

Therefore, f(4) = 16.

The other options are incorrect because they either use the wrong rule (A and D) or miscalculate the result (B).

Answer:

The projected cost of a gallon of oil by next june is $19.60.

Step-by-step explanation:

Given:

Oil prices are projected to increase by 100% by next june.

A quart of oil currently costs $2.45.

Now, to find the cost of a gallon of oil next june.

So, to get the projected cost of a quart of oil by next june:

Cost of one quart of oil currently = $2.45.

Rate of oil prices projected to increase by = 100%.

[tex]100\%\ of\ \$2.45+\$2.45\\\\=\frac{100}{100}\times 2.45+2.45\\\\=2.45+2.45\\\\=\$4.90.[/tex]

Now, to get the projected cost of a gallon of oil by next june we use conversion factor:

4 quart = 1 gallon.

If, 1 quart oil price = $4.90.

Then, 4 quarts oil price = [tex]\$4.90\times 4[/tex] = [tex]\$19.60.[/tex]

Thus, 1 gallon oil price = $19.60.

Therefore, the projected cost of a gallon of oil by next june is $19.60.

Answer:

2.26 meters

Step-by-step explanation:

so the volume for a cylinder is

v= π r² x h

now just substitute in the numbers you know:

180= π r² x 11.25

now rearrange the formula:

180= r² x 11.25π

(rearranging allows you to do this next bit with ease)

now divide by 11.25π on both sides to get

[tex]\frac{180}{11.25\pi }[/tex]= r²

to maintain accuracy, don't divide yet

now you know what r² is but you want r, so square root it:

[tex]\sqrt{\frac{180}{11.25\pi } }[/tex]=r

type that into a calculator and i think the answer is ...

2.25675833419

write the long answer in case you make a mistake when rounding

round appropriately : 2.26 meters   ( I've done it to 2 decimal places)

and hopefully that's the correct answer.

Answer:

width is 25 inches

length is 31 inches

Step-by-step explanation:

We will need the formula for perimeter of a rectangle:

P = 2(l + w)

"l" is length, "w" is width

If the length exceeds the width by 6, then:

l = w + 6       <= Substitute this into the equation

P = 2(l + w)

P = 2(w + 6 + w)

Remember we also know the perimeter is 112:

112 = 2(w + 6 + w)

Collect like terms:

112 = 2(2w + 6)

Start isolating "w" to find width.

56 = 2w + 6             Divided both sides by 2

50 = 2w                    Subtracted 6 from both sides

25 = w                      Divided both sides by 2

w = 25                      Variable on left for standard formatting

The width is 25 inches.

Find the length using "length exceeds width by 6".

l = w + 6

l = 25 + 6            Substitute the width

l = 31

The length is 31 inches.

∴ The length is 31 inches and the width is 25 inches.

Check your answer with the perimeter formula.

P = 2(l + w)

112 = 2(31 + 25)      Substitute all the variables.

112 = 2(56)

112 = 112               Same answer

LS = RS                Left side equals right side

The answer is correct.

Answer: Angle XCB = 46 degrees ( ∠XCB = 46°)

Step-by-step explanation: Please refer to the picture attached for details.

A rhombus basically is a parallelogram with a diamond shape. All four sides have equal length, opposite sides are parallel and opposite angles are equal.

The sides have been labelled ABCD as stated in the question, and the point X is extended to point B to form angle XBC and also extended to point C to form angle XCB. Upon careful observation we shall notice that a triangle has been formed with sides BXC and angle X is a right angle, which measures 90 degrees.

The sum of angles in a triangle equals 180, therefore,

Angle XBC + Angle XCB + Angle X = 180

Substituting for the given values we now have the following;

4a + 12 + 6a - 2 + 90 = 180

10a + 10 + 90 = 180

10a + 100 = 180

Subtract 100 from both sides of the equation

10a = 80

Divide both sides of the equation 10

a = 8

If XCB = 6a - 2,

Substitute for the value of a

XCB = 6(8) - 2

XCB = 48 - 2

XCB = 46

Therefore angle XCB measures 46 degrees.

Answer: 6 floors

Step-by-step explanation: Given that:

The first floor height = 25ft

Where each subsequent floor is 15 ft. tall.

Entry point on car window above horizontal = 12 in.

Distance from car window to victim = 42 in.

Distance from building to victim’s car = 350 ft.

Using similarity in angle method, we have

(25 + 15x)/350 = 12 in/42 in

Convert inches to feet by dividing the value by 12

(25 + 15x)/350 = 1/3.5

Cross multiply

3.5(25 + 15x) = 350

87.5 + 52.5x = 350

52.5x = 350 - 87.5

52.5x = 262.5

X = 262.5/52.5

X = 5

Therefore,

The floor number = 1 + 5 = 6 floors

To determine the shooter's floor number, we divide the distance from the building to the victim's car by the height of each floor. Using the given measurements, the shooter was on the 6th floor.

To determine the floor number from feet, we need to divide the distance from the building to the victim's car by the height of each floor. The height of the first floor is given as 25 ft, and each subsequent floor is 15 ft taller than the previous. We calculate the number of floors using the formula: floor number = (distance from building to car - height of first floor) / height of each subsequent floor. Plugging in the given values, we find that the shooter was on the 6th floor, so the correct answer is option b) 6.

An inverse trigonometric function is a function in which you can input a number and get/output an angle (usually in radians). It is the inverse function of the basic trigonometric functions.

Step-by-step explanation:

Trigonometric functions are derived from ratios of certain sides of a right triangle in reference to an angle. The graph of which is a wave, with amplitude in the y-axis and angle in the x-axis. We will first define the sine function written as:  

sin(θ)=oppositesidehypotenuse

As we can see, the sine function, together with all the other trigonometric functions, relates an angle to the ratio of an opposite side and the hypotenuse of right triangle. The input here is an angle, and the output is a ratio. Therefore, the inverse process to this is actually just a reverse process.  

Let  

y

=

y=sin(θ)

sin−1(y)=θsin−1(oppositesidehypotenuse)=θ

Thus we see, that the input to an inverse trigonometric function is a unitless ratio of two sides of a representative right triangle.

The input to an inverse trigonometric function is a unitless ratio of two sides of a representative right triangle.

We need to find what is the input for inverse trigonometric functions.

An inverse trigonometric function is a function in which you can input a number and get/output an angle (usually in radians).

The inverse trigonometric functions do the same thing as the inverse trigonometric relations, but when an inverse function is used, because of its restricted range, it only gives one output per input--whichever angle lies within its range.

Example:

Inverse sine of 1/2 is the angle of 30°

That is, [tex]sin^{-1}(\frac{1}{2} )=30^o[/tex]

As we can see, the sine function, together with all the other trigonometric functions, relates an angle to the ratio of an opposite side and the hypotenuse of the right triangle. The input here is an angle, and the output is a ratio. Therefore, the inverse process to this is actually just a reverse process.

Therefore, the input to an inverse trigonometric function is a unitless ratio of two sides of a representative right triangle.

Answer: OPTION 1

Step-by-step explanation:

For this exercise you need to remember that, by definition, the Arc length can be calculated with the following formula:

[tex]arc\ length=rC[/tex]

where "C" is the central angle of the arc in radians and "r" is the radius.

Since you need to find the Central  angle, you have to solve for "C" from that formula, as following:

[tex]C=\frac{arc\ length}{r}[/tex]

According to the information given in the exercise, you can identify that:

[tex]arc\ length=100\ m\\\\r=60\ m[/tex]

Answer:

(x+11) by (x+10)

Step-by-step explanation:

We know that Area = Length x width

Given: Area = x²+9x+20

Lets sort this out first

Area = x²+5x + 4x + 20

Area = x(x+5) + 4(x+5)

Area = (x+5) (x+4)

Therefore, it is concluded that:

Length 'l' = (x+5) feet

Width 'w' = (x+4) feet

if a 3-foot walkway is built around the fountain, we'll add 3 feet on both sides

Therefore,

Outer Length = (x+5+3+3) = (x+11) feet
