Identify the measure of arc RT. HELP ASAP!

Answer:

Step-by-step explanation:

Area of octagon = area of square - area of 4 triangles that are formed in four corners

Area of square:

Side = Width of the octagon = 10 cm

Area = side * side

       = 10 * 10

      = 100 cm²

Area of triangle:

Base =  2cm

height =  2 cm

Area =[tex]\frac{1}{2}b*h[/tex]

        =[tex]\frac{1}{2}*2*2[/tex]

       = 2  cm²

Area of octagon = 100 - 2 =  98  cm²

Answer:

14)  [tex]\frac{1}{2} n-1[/tex] (half of n is [tex]\frac{1}{2} n[/tex] and subtract that with 1)

15) 3o+4 ( multipy o with 3, it becomes "3o" and add that with "4")

16) 5p-2 (same concept as No.15)

17) 7+r ( add 7 with "r")

18) s+7 (same concept with No.18)

19) t-10 (subtract 10 from "t")

20) 10-u ( subtract "u" from 10)

21) 2v ( multiply 2 with v)

22) 2w (same concept as No.21)

23) [tex]\frac{x}{5}[/tex] (divide x with 5 and show the result in fractions)

24) [tex]\frac{5}{y}[/tex] ( divide 5 with y and show the result in fractions)

Tip : Alphabets and numbers never combine unless you multiply them with it (eg. 3*x = 3x) but ( 3+x stays like that ).

Answer:

Step-by-step explanation:

a. the inequality is x+y >= 2  (red line) that keeps onlythe two farms in the region.

b. substituting the coordinates of the farms in the inequality and see if they are satisfied:

C(2,2)  2+2 = 4 > 2    checks

F(3,4)   3+4 = 7 > 2    checks.

The other farms will not , for example,

D(1,-2) 1-2 = -1 < 2     does not check.

...

c. y > -4x + 3 is shown in blue.

Farms that satisfy given inequality can raise chickens, i.e. to the right of the blue line, or farms C,E and F.

If necessary, we can again check by the coordinates as in part b.

C(2,2)   -4(2) + 2 = -8+2 = -6   y=2 > -6, so checks.

Hey there! :)

Answer:

5a².

Step-by-step explanation:

Solve this expression by finding how many times 9a² goes into [tex]45a^{4}[/tex]. Since we are only dividing from a monomial, long division does not need to be used.

Begin by solving for the coefficient:

45 ÷ 9 = 5.

Solve for the exponent of a:

[tex]a^{4}[/tex] ÷ a² (subtract exponents when dividing) = a². Therefore:

[tex]45a^{4}[/tex] ÷ 9a² = 5a².

Answer:

-1 10/17

Step-by-step explanation:

Answer:

y = 1 10/17

Step-by-step explanation:

The LCD is 9y.  Multiply all three terms by 9y:

(9y)(12)                   (9y)(4)

----------- + 8(9y) = -----------

     y                           9

This reduces to 108 + 72y = 4y, or 108 = -68y

Dividing both sides by 68, we get y = 1 10/17

We can use a ratio to solve

24.95               x dollars

---------------- = ----------------

9 melons          17 melons

Using cross products

24.95 * 17 = 9x

Divide by 9

24.95 * 17/9 = x

47.127777777 = x

Rounding to the nearest cent

47.13 for 17 melons

Answer:

$47.12

Step-by-step explanation:

We know that 1 box has 9 lemons and each box is $24.95. Therefore, 1 lemon costs 24.95/9 dollars. That leads us to know that 17 lemons cost (24.95/9 * 17). Once we plug that into the calculator and round to the nearest hundreth place, we get $47.12.

Answer:

A. 3

Step-by-step explanation:

Let the integers be

x

(x+1)

(x+2)

(x+3)

Sum the integers

We have,

x+(x+1)+(x+2)+(x+3)=18

x+x+1+x+2+x+3=18

4x+6=18

Subtract 6 from both sides

4x-6=18-6

4x=12

Divide both sides by 4

4x/4=12/4

x=3

The smallest integer which is x is equal to 3

Answer:

Step-by-step explanation:

The equation of graph g(x) = f(-x) as it has been rotated along y-axis and the maximum coordinates of g(x) is (-3, 4).

A function can be thought of as output for the given set of inputs. The output is called the dependent variable and the inputs are called the independent variable.

We know when we rotate a function along the y-axis sign of x changes.

Given a function y = f(x) after rotation along y-axis it becomes y = f(-x) = g(x)

and if the given function is odd f(-x) becomes -f(x).

Also given that the maximum point of f(x) = (3, 4).

∴ Function  g(x) will have maximum at coordinates (-3, 4).

Answer:

1 < x < 3

(1 , 3)

Step-by-step explanation:

We have been provided with a set that is

{x|1 < x < 3}

We have to write it in both as an inequality and also in the form of interval notation.

The inequality can be found easily by just looking at the given set. It states that the set contains x, such that x is greater than 1 and x is smaller than 3, so the inequality can be written as:

1 < x < 3

To write in interval notation, we use brackets, As both 1 and 3 are not included, we'll use round brackets to show the interval.

(1 , 3)

Answer:   x < 3

Step-by-step explanation:

Answer:

Step-by-step explanation:

a) angle CAD= angle ODA ( in triangle OAD, OA=OD(same radius) angels opp                          to equal sides are equal)

hence angle CAD=42

b)angle b =90(angle subtended by diameter)

hence using angle sum property in triABC,

angle ACB=66-------------eq4

c) in tri OAD,

Angle AOD=180-(42+42)-------(using angle sum prop.)

=> 96-----------------eq1

angleACD=1/2 Angle AOD ( angle subtende by an arc at centre is double the angle subtended...)

hence angle ACD =1/2 x 96(from eq1)

angleACD=48--------------eq3

from eq 3,and eq4,

angle BCD= 48+66

=114 degree...

hope this helped you........pls mark brainliest

a) Measure of angle CAD is, 42°

b) The size of ACB is, 66°

c) The size of angle BCD is, 114°

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Given that;

In the diagram O is the center of the circle.

And, AOC is a straight line.

Here, Angle BAO is 24° and Angle ADO is 42°​.

Now,

a) In triangle OAD,

⇒ OA=OD (same radius)

And, Angels opposite to equal sides are equal.

Hence, We get;

⇒ ∠CAD= ∠ODA

⇒ ∠ CAD = 42°

b) We have;

⇒ ∠B =90     (Angle subtended by diameter)

Hence, By using angle sum property in ΔABC,

⇒ ∠ BAC + ∠ACB + ∠B = 180°

⇒ 24 + ∠ACB + 90° = 180°

⇒ ∠ ACB = 66°

c) In ΔOAD,

⇒ ∠AOD = 180 - (42 + 42)   ( By using angle sum property)

              = 96

And, Angle subtended by an arc at center is double the angle subtended.

Hence, We get;

⇒ ∠ACD = 1/2 ∠AOD

               = 1/2 × 96

               = 48°

Hence, We get;

⇒ ∠ BCD = 48° + 66°

               = 114°

Answer:

As x —> infinity, g(x)—> infinity, and as x —> Negative infinity, g(x) —> Infinity

Step-by-step explanation:

Because

The end behavior of the graph will be as x tends to infinity, g(x) will tend to infinity, and as x tends to Negative infinity, g(x) tend to Infinity.

A quadratic, cubic, quartic, and other functions involving only non-negative integer powers of x are examples of polynomial functions. We can define a polynomial's degree and provide a generic definition for it.

A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.

The given function is g(x)=5x ⁶+x⁵+9x³-12x-125 will have the end behavior of the graph as x tends to infinity, g(x) will tend to infinity, and as x tends to Negative infinity, g(x) tend to Infinity.

Answer:

i think it's 100

Step-by-step explanation:

100 is the interval which would not be used for the stems of a stem-and-leaf plot.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

In a stem-and-leaf plot, the stem is typically the leftmost digits of a number and the leaf is the rightmost digit.

The stem represents the largest common place value of the numbers being plotted.

If the data set is {12, 15, 21, 26, 30, 31, 35, 38}, the stem would be the tens place and the leaf would be the ones place.

The stem values would be 1, 2, 3, and 4.

Therefore, the interval for the stems should be determined by the range of the data set.

Hence, 100 is the interval which would not be used for the stems of a stem-and-leaf plot.

Answer:

Option B.

Step-by-step explanation:

If a line passing through two points, then the slope of line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that f(x) passing through the points (0,-2) and (1,1). So, slope of f(x) is

[tex]m_1=\dfrac{1-(-2)}{1-0}=1+2=3[/tex]

It is given that g(x) passing through the points (-4,0) and (0,2). So, slope of g(x) is

[tex]m_2=\dfrac{2-0}{0-(-4)}=\dfrac{2}{4}=\dfrac{1}{2}[/tex]

Since, [tex]\dfrac{1}{2}<3[/tex], therefore [tex]m_2<m_1[/tex].

The slope of g(x) is less than the slope of f(x).

Therefore, the correct option is B.

Answer:

(4.462, 19.411)

Step-by-step explanation:

From the description, the functions are:

f(x) = (11/5)^(x - 7/10)

g(x) = 1/8x² + 2x + 8

(Notice that 2 2/10 is equivalent to 22/10 = 11/5)

In the picture attached, the plot of the functions is shown. The exponential is in red and the quadratic is in blue. The exponential function begins to exceed the quadratic function from point (4.462, 19.411)

Step-by-step explanation:

In the above question, we have been given a rule to follow

Given a * b = ba−ba+ab

We are to find (2*3)×(3*2)

Let simplify each bracket first

a * b = ba−ba+ab

2*3, a = 2, b = 3

2*3 = 3×2 - 3×2 + 2×3

= 6 - 6 + 6

= 6

a * b = ba−ba+ab

3*2, a = 3, b = 2

3*2 = 2×3 - 2×3 + 3×2

= 6 - 6 + 6

= 6

(2*3)×(3*2)

= 6 × 6

= 36
