If a⊕ b= 1 / a + 1 / b, for what decimal value of a is a⊕ 0.2 = 10?

Mathematics
1 answer:
andriy [413]3 years ago
5 0

Answer:

a = 0.2

Step-by-step explanation:

Given the operation a⊕ b= 1 / a + 1 / b, it can be inferred from the operation that a is similar to 1/a and b is similar to 1/b.

For the operation a⊕ 0.2 = 10, on applying the rule above;

1/a+1/0.2 = 10

1/a + 5 = 10

1/a = 10-5

1/a = 5

a = 1/5

a = 0.2

A 12 foot ladder is leaning against a wall and the foot of the ladder is 5 feet away from the wall. What is the angle between th
Pepsi [2]

Answer:

65.38degrees

Step-by-step explanation:

Given the following

Length of ladder = 12foot = hypotenuse

Distance of the ladder from the wall = 5ft = adjacent

Required

Angle between the ground and the ladder theta

Using the SOH CAH TOA identity

Cos theta = adj/hyp

Cos theta = 5/12

Cos theta = 0.41667

theta = arccos(0.41667)

theta = 65.38 degrees

Hence the angle between the ground and the floor is 65.38degrees

What expression is equivalent to the area of metal sheet required to make this square-shaped traffic sign?
AveGali [126]

Answer: \text{Area of the square shaped traffic sign }=16x^2+9+24x

Step-by-step explanation:

Given: The side of the square shaped traffic sign = 4x+3

We know that the area of square is given by:-

Area= side^2

Therefore, the area of the side of the square shaped field is given by:-

Area=(4x+3)^2

We know that , (a+b)^2=a^2+b^2+2ab

Therefore,

(4x+3)^2=(4x)^2+(3)^2+2(4x)(3)\\=16x^2+9+24x

Hence, \text{Area of the square shaped traffic sign }=16x^2+9+24x

What does the dotted line in the diagram imply about the number of triangles you can construct from the given information
nekit [7.7K]

Answer:

Step-by-step explanation:A triangle is aptly named: it is composed of three (tri) angles formed by three non-coincident, non-parallel lines. That the lines are non-coincident means they do not overlap, and that they are non-parallel means that each line intersects with every other line. Correspondingly, a triangle also has three sides.
