You need to know these two formulas:

\huge a^b \times a^c = a^{b+c}\\\\\huge \frac{a^b}{a^c}=a^{b-c}

For example,

5^2 \times 5^3 = 5^{2+3} = 5^5

\frac{2^6}{2^4} = 2^{6-4} = 2^2

Box A contains 10 pens that are either red or blue in colour. Box B contains 23 pens that are also either red or blue in colour.
NISA [10]

Answer:

b + r = 10 - - (1)

2r + 3b = 23 - - (2)

Step-by-step explanation:

Number of Blue pens in box A = b

Number of red pens in box A = r

BOX A :

Contains 10 pens that are either red or blue

b + r = 10

BOX B:

Contains 23 pens that are either red or blue ;

Red pens in box B = 2 tines the number of red pens in box A

Blue pens in box B = 3 times the number of blue pens in box A

2r + 3b = 23

\\ \sf\longmapsto 1+tan^2A

\boxed{\sf tanA=\dfrac{sinA}{cosA}}

\\ \sf\longmapsto 1+\dfrac{sin^2A}{cos^2A}

\\ \sf\longmapsto \dfrac{cos^2A+sin^2A}{cos^2A}

\boxed{\sf cos^2A+sin^2A=1}

\\ \sf\longmapsto \dfrac{1}{cos^2A}

\\ \sf\longmapsto \dfrac{1}{1-sin^2A}

\\ \sf\longmapsto \dfrac{1}{1}-\dfrac{1}{sin^2A}

\\ \sf\longmapsto \dfrac{1}{sin^2A}

Hence verified

Answer:

m<-2

Step-by-step explanation:

-4m-3.65>4.35

-4m>4.35+3.65

-4m>8

4m<-8 (the greater than or less than sign flips when you multiply or divide by the - sign)

m<-2 (divide both sides by 4)
