Answer:
Step-by-step explanation:
Given expression:
The given expression needs to be simplified to the form 
Applying the exponents rule to simplify.
Writing all numbers as product of 3.
⇒ 
Writing each in exponents form.
⇒ 
Using power of a power rule ![[\ (a^x)^y=a^{xy}\ ]](https://tex.z-dn.net/?f=%5B%5C%20%28a%5Ex%29%5Ey%3Da%5E%7Bxy%7D%5C%20%5D)
⇒ 
Using multiplication rule of exponents ![[\ a^x\times a^y=a^{x+y}\ ]](https://tex.z-dn.net/?f=%5B%5C%20a%5Ex%5Ctimes%20a%5Ey%3Da%5E%7Bx%2By%7D%5C%20%5D)
⇒ 
⇒ 
So we have 
∴
Answer:
1
Step-by-step explanation:
b= -2, b2 +6b +9
=-2(2)+6(-2)+9
=-4-12+9
=4+9-12
=13-12
=1
A) Minute Hand:
in 1 hour (= 60 minute) the minute hand travels 360 °
So in each minute, the minute hand travels 360/60 = 6°
And in x minute it will travel x.(6°)
B) Hour Hand:
in 1 hour (= 60 minute) the hour hand travels 360/12 = 30°
So in each minute, the hour hand will travel 30°/60° = 0.5°
And in x minute it will travel x.(0.5°)
ANGLE AT 4:35?
At 4:00, angle = 4. 30 = 120°
After 35 minutes, the minute hand strops at 35.(6°) = 210°, but during this 35 minute, the hour hand traveled 35.(0.5) = 17.5°, on top of its 120°, that makes an angle of 137.5°
So at 4:35 the angle between the hour & minute hand = 210°-137.5° =72.5°
Answer A
Answer:
The correct option is B.
Step-by-step explanation:
The area of triangle is
Where, b is the base of the triangle and h is the height of the triangle.
It is given that the base of the triangle is 10 inch and the height of the triangle is 14 inch.
The area of given triangle is
Therefore the area of triangle is 70 square inch and the option B is correct.
