In right AABC with mzC-90°, mzB-75°, and AB = 12 cm. Find the area
of AABC.

The slope-intercept form is y = mx + b.

If the value of m = -6 and b = 9 then 6x + y = 9 be the standard form.

Y = mx + b is the general formula for the slope-intercept form, where m stands for the line's slope and b for the y-value of the line's y-intercept. We may more easily determine a line's slope and its y-axis intersection using the slope-intercept form of a linear equation.

Let the value of m = -6(slope)

b = 9 (y -intercept)

The slope-intercept form is given by,

y = mx + b

y = -6x + 9

Therefore,  y = -6x + 9  is the slope-intercept form

Standard form is given by, Ax + By = C

Since, slope-intercept form is y = -6x + 9

⇒ 6x + y = 9

Therefore, 6x + y = 9 is the standard form.

What is Irrational Number?

An Irrational number is areal number that cannot be expressed as a ratio of integers; for example [tex]\sqrt{2}[/tex] is an irrational number. We cannot express any irrational number in the form of ratio, such as p/q, where p and q are integers, q[tex]\neq[/tex] 0. Again, the decimal expansion of an irrational number in neither terminating nor recurring.

Let us assume [tex]7\sqrt{56}[/tex] is rational.

So, we can write this number as

[tex]7\sqrt{56}[/tex] = a/b __(1)

Here, a and b are two co-prime numbers and b is not equal to zero.

Simplify the equation (1) divide by 7 both sides, we get

[tex]\sqrt{56}=\frac{a}{7b}[/tex]

Here, a and b are integers, so a/7b is a rational number, so [tex]\sqrt{56}[/tex] should be a rational number.

But [tex]\sqrt{56}[/tex] is a irrational number, so it is Contradictory.

Therefore, [tex]7\sqrt{56}[/tex] is irrational number.

The distance between Amy's initial and final position is 1 mile and she is facing South direction

It is given that,

Amy first moves towards East direction in reference to her initial position  for 2 miles

The distance covered by Amy in East direction = 2 miles

Then,

Amy moves towards South direction in reference to her initial position(facing East side) for 3 miles

The distance covered by Amy in South direction = 3 miles

We need to find,

The distance between Amy's initial and final position which will be given by the displacement between both points

Let's say that the positive direction is East and the negative direction is south.

The distance covered by Amy in East direction = + 2 miles

The distance covered by Amy in South direction = - 3 miles

Then , +2 +(-3) = -1

Answer:

108°

Step-by-step explanation:

Since angle WYT and angle UYW lie on the same line, we can use linear pair fidn the answer.

That is: 180-72= angle UYW

Therefore angle UYW=108°

-Hence proved:)

The measures of the angle and it's supplement are144°  and 36° respectively.

The measure of the supplement of an angle is four times the measure of the angle. (given)

Let us consider the value of the supplement be X°.

Therefore the value of the angle  is 4X°

 180 - X = 4X

  X = 36° (The value of supplement)

180°-X = 144°( The value of angle)

Hence the angles are 36° and 144° .

the maximum time that he can have in his last race is 23 seconds.

We know that the average can not be greater than 22.8 seconds, then if x represents the time of the last race, the maximum value that x can take is given by the equation:

(23.1 + 23.2 + 22.8 + 21.9 + x)/5 = 22.8

(That is the equation for the mean of the 5 times)

Solving that for x we will get:

(23.1 + 23.2 + 22.8 + 21.9 + x) = 5*22.8

91 + x = 114

x = 114 - 91 = 23

Using Substitution method,

From the equation (1) [tex]x-2y=4[/tex] , the value of x is

3x + y = 4                             equation (2)

Using Substitution method,

From the equation (1) i.e., x - 2y = 4 , the value of x is

x = 4 + 2y

Putting the value of x in equation (2), we get

3 ( 4 + 2y ) + y = 4

⇒ 12 + 6y + y = 4

⇒ 12 + 7y = 4

⇒ 7y = (-8)

⇒ y = (-8/7)

Now, putting the value of y in equation (1), we get

x - 2 ( -8/7 ) = 4

⇒ x + ( 16/7 ) = 4

⇒ x = 4 - ( 16/7 )

⇒ x = ( 28 - 16 )/ 7

The given equation is an identity, so it is true for any value of x, and x can take infinite values, thus, the linear equation has infinite solutions.

Here we have the linear equation:

x - 2 = -2 + x

And we want to see how many solutions it has, so let's solve it.

IF we add 2 in both sides we will get:

x - 2 + 2 = -2 + x + 2

x + (-2 + 2) = x + (-2 + 2)

x = x

The common ratio of the geometric sequence 4, 10, 25, 62.5, . . . is 2.5. The answer is B.

A geometric sequence refers to a sequence of numbers, which the next term is obtained by multiplying the previous term with a constant, called a common ratio.

a(n) = a r^(n-1)

Where:

a(n) = nth term

a = first term

r = common ratio

The common ratio must be the same for all pairs of succeeding term to be called a geometric sequence.

To find the common ratio, use the formula

a(n) = a r^(n-1)

let n = 2, a = 4, a(2) = 10

10 = 4(r^(2 - 1)

10 = 4(r)

r = 2.5
