Fundamental Trigonometric Identities are listed below:

$sin^{2}$ Θ + $cos^{2}$ Θ = 1
$sec^{2}$ Θ - $tan^{2}$ Θ = 1
$cosec^{2}$ Θ - $cot^{2}$ Θ = 1
sinΘ = 1 / cosec Θ
cos Θ = 1 / sec Θ
tan Θ = 1 / cot Θ
tan Θ = sinΘ / cosΘ
cotΘ = cosΘ / sinΘ

<h3>Meaning of Fundamental Trigonometric Identities</h3>

Fundamental Trigonometric Identities can be defined as the basic identities or variables that can be used to proffer solutions to any problem relating to angles and trigonometry.

In conclusion, A few Fundamental Trigonometric Identities are listed above.

A Pizza factory has come out with two kinds of pizzas.A square pizza of side 26 cm costs AED 80 and a circular pizza of diameter

DiKsa [7]

Answer:

Square pizza

Step-by-step explanation:

To obtain which pizza is the best buy:

Cost of square pizza :

AED 80

side length, s = 26cm

Area of square, A = s²

A = 26² = 676 cm²

1 AED of square pizza gives : 676 / 80 = 8.45 cm²

Cost of circular pizza :

AED 80

Radius, r = 28cm

Area of circle, A = πr²

A = 22/7 * 14 * 14 = 22 * 2 * 14 = 616 cm²

1 AED of circular pizza gives : 616 / 80 = 7.7cm²

Hence, square pizza is the better buy ;

8.45cm² > 7.70 cm²

Write the equation of the line that passes through (3, 4) and (2, −1) in slope-intercept form. (2 points) a y = 3x − 7 b y = 3x

sashaice [31]

Answer: y = 5x − 11

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis represent

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

The line passes through (3,4) and (2, -1),

y2 = - 1

y1 = 4

x2 = 2

x1 = 3

Slope,m = (- 1 - 4)/(2 - 3) = - 5/- 1 = 5

To determine the y intercept, we would substitute x = 3, y = 4 and m= 5 into

y = mx + c. It becomes

4 = 5 × 3 + c

4 = 15 + c

c = 4 - 15 = - 11

The equation becomes

y = 5x - 11

Is w^2-9w+81 a trinomial square

Yuri [45]

No because it would be
if you knew that
ax^2+bx+c was a trinomial square, then the factored form would be
$( \sqrt{a}x+ \sqrt{c})^{2}$ or $( \sqrt{a}x- \sqrt{c})^{2}$
so
if w^2-9w+81 is perfect square, factored form is either
$( \sqrt{1}x+ \sqrt{81})^{2}$ or $( \sqrt{1}x- \sqrt{81})^{2}$ aka $( x+9)^{2}$ or $( x-9)^{2}$
expand them
(x+9)^2=x^2+18x+81, wron middle term

(x-9)^2=x^2-18x+81 wrong

so it is not
