What basic trigonometric identity would you use to verify that (sin2x + cos2x)/cosx=secx
Oksana_A [137]

Answer:

Step-by-step explanation:

sin(2x) = 2 sin(x) cos(x) cos(2x) = cos2(x) – sin2(x) = 1 – 2 sin2(x) = 2 cos2(x) – 1. Now I am not sure if this is right but I remember another similar formula. Here is the correct formula cot x = cos x / sin x

2 ) ( sin² x + cos² x ) / cos x = sec x

1/cos x = sec x

sec x = sec x

cos² x + sin² x = 1

Select the correct answer. Which expression is equivalent to this polynomial? 15x − 24 A. 5(3x − 8) B. 3(5x − 5) C. 3(5x − 24) D
Scilla [17]

15x-24

the answer is not B because 3*-5= -15, we need -24

the answer is not C because 3*-24= -72

the answer is not A because 5*8= 40

Answer :

D. 3(5x − 8)

(3)(5x)(3)(-8)

15x-24= 15x-24

Cuanto es la respuesta de -126=14k?
N76 [4]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \text{k =   - 9}}}}}

Step-by-step explanation:

\star{ \text{ - 126 = 14k}}

\text{step \: 1 \: : Intercambia los lados de la ecuación}

\hookrightarrow{ \sf{14k =  - 126}}

\text{step \: 2 : Divide ambos lados por 14}

\hookrightarrow{ \sf{ \frac{14k}{14}  =  \frac{ - 126}{14}}}

\text{step \: 3 \:  : Calcular}

\hookrightarrow{ \sf{k =  - 9}}

\text{el valor de k es  - 9}

------------------------------------------------------------

Translation in English:

Step 1 : Swap the sides of the equation

Step 2 : Divide both sides by 14

Step 3 : Calculate
