We want to study the angle of an arc given that the length of the said arc is smaller than the radius of the circle.

The correct option is:

"it is less than pi radians"

A circle of radius R has a circumference:

C = 2*pi*R

An arc defined by an angle θ has a length:

L = θ*R

Now, we know that the length of the arc is smaller than the radius, then we have:

θ*R < R

Dividing both sides by R we get:

θ < 1

So we can see that the correct option is:

"it is less than pi radians"

Because it is smaller than 1.

Answer:

D or the last option

Step-by-step explanation:

38/6, so 6 can go on 38 6 times, means it will be 6 times 6, which is 36. So, we can eliminate the answers A and B.

38-36 = 2, which is the left over. Now You add a decimal point and bring down a zero and make it 20. and 6 can go on 20, 3 times... 6 times 3, which is 18.

20-18= 2, so you do the same thing over and over again, the answer is 6.3

Answer:

With the metric system, the formula for BMI is weight in kilograms divided by height in meters squared. Since height is commonly measured in centimeters, an alternate calculation formula, dividing the weight in kilograms by the height in centimeters squared, and then multiplying the result by 10,000, can be used.

An algorithm is the series of steps followed to do calculations especially by a computer.

[tex]\frac{1}{4}[/tex] × [tex]\frac{2}{3}[/tex] = [tex]\frac{2}{12}[/tex]  =[tex]\frac{1}{6}[/tex]

The algorithm would use the multiplication of the numerator with the numerator and the denominator with the denominator for solving simple multiplication of the proper fractions.

[tex]\frac{1}{4}[/tex] × [tex]\frac{2}{3}[/tex]

= (1×2)/(4×3)  ⇒ the numerators are multiplied and so the denominators

= 2/12

Now 2 is taken as common from both 2 and 12 ( numerator and denominator)

= (2/2 ) 1/6   taking 2 as common factor

= 1/6         cancelling 2 by 2

The diagram can be used to explain the same fact.

1 is multiplied with 2 and 4 is multiplied with 3.

Therefore we get 2 as numerator and 12 as denominator.

2/12 is further reduced to 1/6

Answer:

Step-by-step explanation:

Multiply the numerator by the reciprocal of the denominator.

251

300

= 56

Any number can be converted to fraction if you use one for the denominator:

84/1

Therefore now that we've converted 84 into the fraction, to work out the lowest term, we put the fraction 2/3 side by side with our new fraction, 84/1 so that we should multiply those 2 fractions.

all you need to do is convert the whole number into the fraction or then multiply the numerators or denominators :

2 x 84 / 3 x 1

= 168 / 3

In this situation, our new fraction shall actually be the simplified down further. To do that, we want to find the greatest common factor of those numbers.

We can now sum both the new numerator or the denominator by the three to simplify this fraction down to its lowest terms.

168/3 = 56

3/3 = 1

When we put that together, we could see that our complete solution is:

56/1

= 56

( 5 , - 3 ) -------> ( 3 , 5 )

Step-by-step explanation:

After the rotation of 270° clockwise about the origin, the coordinate will become (3, - 5).

Given is a figure rotated 270° clockwise about the origin.

The algebraic rule for a figure that is rotated 270° clockwise about the origin is -

(x, y) → (y, -x)

Initial point marked on the figure : (5, 3)

After the rotation, the points will be : (3, - 5)

Therefore, after the rotation of 270° clockwise about the origin, the coordinate will become (3, - 5).

Answer:

Step-by-step explanation:

The system of linear equations intersect exactly at one point. This point where the two lines intersect is the solution of the system of equations.

Step-by-step explanation:

Given,

S = 4LW + 2WH

S = 138

L = 9

W = 3

so value of H,

→ 138 = 2(9)(3) + 2(3)H

→ 138 = 54 +6H

→ 6H = 138 - 54 = 84

→ H = 84/6 = 14

therefore, value of H is 14.

No it isn't. Using the substitution method, if we substitute x for 0, we get

y = 6(0)+7

y = 0+7

y = 7

y = 0+7

y = 7

Answer:

Step-by-step explanation:

To find measures of angles m and n

The triangle to the left has three sides of equal length.

This means that it will also have three angles of equal measure.

The internal angles of a triangle sum to 180°

So the internal angles of the left triangle are 180/3 = 60°

The top right angle is made up of one of the 60° angles and angle n

60 + n = 90

n = 30°

Again the internal angles of a triangle sum to 180°, so the right triangle

m + n + 90 = 180

m = 180 - 90 - 30

m  = 60°

or we could realize that the top and bottom horizontal lines are parallel because the vertical line on the right makes right angles to both of them.

Knowing that they are parallel, we also know that angle m and the top right 60° angle of the left triangle are opposite internal angles of a line intersecting parallel lines and must be identical angles, therefore

m = 60°

F(x) = 25x² - 100

g(x) = 1/5x

{ 7 1/5x² - 100 = y

{ 1/5x = y

∴  25 x² - 100 = 1/5x

x = 2

y = 0.4

The function for the amount of money earned, the total amount of money for 40 hours and the expression for the difference quotient are given as A(x) = 5x³ - 20x, 319200 and 15x² - 15xh - 20 respectively.

A function y = f(x) is defined as a one to one relation between sets X and Y. The set X is called the domain while Y is called the range of f(x).

The given function for earned money in designing house is,

f(x) = 25x² - 100

The function for number of rooms decorated is,

g(x) = x/5

PART A :

As per the problem, the the function for the amount of money made by interior designer is the product of functions f(x) and g(x) as,

A(x) = f(x)g(x)

=> A(x) = (x/5)( 25x² - 100)

=> A(x) = 5x³ - 20x

Where x represents the number of hours worked.

PART B :

If the designer works for 40 hours the amount of money earned can be obtained by substituting x = 40 in A(x) as follows,

A(x) = 5x³ - 20x

at x = 5

A(5) = 5 × 40³ - 20 × 40

       = 319200

PART C :

The difference quotient for the function A(x) is given as,

(A(x + h) - A(x))/h

= (5(x + h)³ - 20(x + h) - (5x³ - 20x))/h

= (15x²h - 15xh² - 20h)/h

=  15x² - 15xh - 20

Hence, the answers for all the parts are A(x) = 5x³ - 20x, 319200 and 15x² - 15xh - 20 respectively.
