Mathematics
1 answer:
nordsb [41]3 years ago

Answer:

Order from greatest to least: 10.5, 3\pi +1, \sqrt{105}

Step-by-step explanation:

step 1 simplify each number

3π + 1  = 10.4247779

*round to the nearest tenth*

3π + 1 = 10.4

\sqrt{105} =10.2469507

*round to the nearest tenth*

\sqrt{105} =10.2

10.5 = 10.5

Now that we have simplified each number we can easily put them in order from greatest to least

10.5 is the greatest number

10.4 is the middle number

10.2 is the lowest number

so 10.5, 10.4, 10.2

Now we put them back in the original form

10.5 = 10.5

10.4 = 3π + 1

10.2 = \sqrt{105}

Your answer is

10.5 , 3\pi + 1, \sqrt{105}

Giving that ai +bj 5i-2j are perpendicular find the value of a if b=3​
Nonamiya [84]

Answer:

a = \frac{6}{5}

Step-by-step explanation:

Given

ai + bj and 5i - 2j are perpendicular and b = 3, that is

ai + 3j and 5i - 2j are perpendicular, then

The scalar product = 0 , that is

5a - 6 = 0 ( add 6 to both sides )

5a = 6 ( divide both sides by 5 )

a = \frac{6}{5}

Please Answer ASAP ! Which point lies on the circle represented by the equation x2 + (y − 12)2 = 252?
Ivahew [28]

Answer:

Point (20 , -3) lies on the circle ⇒ (A)

Step-by-step explanation:

The point which lies on the circle must satisfy the equation of the circle

The equation of the circle is x² + (y - 12)² = 25²

<em>Take the left hand side and substitute x and y by the coordinates of each point the answer must equal the right hand side</em>

<em />

A. (20 , -3)

∵ x = 20

∵ y = -3

∴ (20)² + (-3 - 12)² = 400 + (-15)² = 400 + 225 = 625

∵ The right hand side is 25²

∵ 25² = 625

∴ The left hand side = The right hand side

∴ Point (20 , -3) satisfy the equation of the circle

∴ Point (20 , -3) lies on the circle

B. (-7 , 24)

∵ x = -7

∵ y = 24

∴ (-7)² + (24 - 12)² = 49 + (12)² = 49 + 144 = 193

∵ The right hand side is 25² = 625

∴ Point (-7 , 24) does not lie on the circle

C. (0 , 13)

∵ x = 0

∵ y = 13

∴ (0)² + (13 - 12)² = 0 + (1)² = 0 + 1 = 1

∵ The right hand side is 25² = 625

∴ Point (0 , 13) does not lie on the circle

D. (-25 , -13)

∵ x = -25

∵ y = -13

∴ (-25)² + (-13 - 12)² = 625 + (-25)² = 625 + 625 = 1250

∵ The right hand side is 25² = 625

∴ Point (-25 , -13) does not lie on the circle
