6.	Write the answer of e(a) (-7) (-7)
Answer» .. LET the MEASURE of the complementary ANGLE be a. 40 + a = 90 ∴ a = 50° Hence, the measure of the complement of an angle of measure 40° is 50° (ii) Let the measure of the complementary angle be a. 63 + a = 90 ∴ a = 27° Hence, the measure of the complement of an angle of measure 63° is 27° (iii) Let the measure of the complementary angle be a. 45 + a = 90 ∴ a = 45°

6.

Write the answer of e(a) (-7) (-7)

Answer»

..

LET the MEASURE of the complementary ANGLE be a.

40 + a = 90

∴ a = 50°

Hence, the measure of the complement of an angle of measure 40° is 50°

(ii)

Let the measure of the complementary angle be a.

63 + a = 90

∴ a = 27°

Hence, the measure of the complement of an angle of measure 63° is 27°

(iii)

Let the measure of the complementary angle be a.

45 + a = 90

∴ a = 45°

Answer»

GIVEN,

An expression, a(a²+ a +1)+1.

To Find,

The simplification of this expression with the value of a = -1.

Solution,

Given expression = a(a²+ a +1)+1.

[Substituting the value of a = -1]

= -1(-1² + -1 + 1)+1

In the brackets:

→ -1² = -1 X -1 = 1

→ -1 + 1 GETS CANCELLED as the add UPTO 0.

By simplifying, we get it as:

-1 x 1 + 1

= -1 + 1

= 0

Therefore by simplifying the expression a(a²+ a +1)+1 with the value of a = -1, we get the answer as 0.

((a-b)(a-b))-c^2

(a-b)^2-c^2

Set X =a-b and y=c. The formula becomes

Answer» Answer: Step-by-step explanation: Loud noise can damage cells and membranes in the cochlea. Listening to loud noise for a long time can overwork hair cells in the ear, which can cause these cells to die. The hearing loss progresses as long as the exposure continues. Harmful effects might continue even after noise exposure has stopped. A time period (denoted by 'T' ) is the time taken for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the time period of the wave decreases. The unit for time period is 'seconds'. The main disadvantage of friction is that it produces heat in various parts of machines. In this way some useful energy is wasted as heat energy. Friction is reduced by adopting the following methods: 1. By POLISHING the surfaces. 2. By applying oil or grease on the surfaces ( or by lubrication). Ball bearings use balls to separate two “races,” or bearing rings, to reduce surface contact and friction across moving planes. Because there is little surface contact between the balls and races, ball bearings typically have a lower load capacity for their size than other rolling-element bearings. Sound is transmitted as sound waves from the ENVIRONMENT. The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. The sound waves cause the eardrum to vibrate, which sets the THREE tiny bones in the middle ear into motion. The motion of the bones causes the fluid in the inner ear or cochlea to move. The movement of the inner ear fluid causes the hair cells in the cochlea to bend. The hair cells change the movement into electrical pluses. These electrical impulses are transmitted to the hearing (auditory) nerve and up to the brain, where they are INTERPRETED as sound. A system has to burn more energy in order to overcome the force of friction. This results in reduced efficiency. Friction also limits the life of mechanical components are they wear away over a period of time . as friction is a necessary evil it is not advisable to reduce it always or most often
