if m<4=35 degrees, find m<2 and m<3

The approximate angle will be made by the stairway with the ground is 46.24°.

As we are been given that, the length of the stairway from the ground is 18 feet, under the right angle triangle, that will be the length of the hypotenuse. Next, since the elevation of the top of the stairway from, the ground is 13 feet, which is considered to be the length of the perpendicular of the assumed right angled triangle.

Now, we are asked to find the angle x,

Since, we know  that

                      sin θ = perpendicular/ hypotenuse

So, substituting the required values the desired angle we get is :

                            sin θ = 13/18

                            sin θ = 0.7222

                              θ  = sin ⁻¹ (0.7222)

                                  = 46.2364

                             x  = 46.24

the angle θ or x is 46. 24°.

Answer:

The two circles intersect at one and only point A(0 , 0)

Step-by-step explanation:

Let ς₁ be the circle of equation :

ς₁ : (x - 2)² + y² = 4

and ς₂ be the circle of equation :

ς₂ : (x + 2)² + y² = 4 

Consider the point M (x , y) ∈ ς₁∩ς₂

M  ∈ ς₁ ⇔ (x - 2)² + y² = 4

M  ∈ ς₂ ⇔ (x + 2)² + y² = 4

M (x , y) ∈ ς₁∩ς₂ ⇒ (x - 2)² + y² = (x + 2)² + y²

⇒ (x - 2)² = (x + 2)²

⇒ x² - 4x + 4 = x²+ 4x + 4

⇒  - 4x = 4x

⇒  8x = 0

⇒  x = 0

Substitute x by 0 in the first equation:

(0 - 2)² + y² = 4

⇔ 4 + y² = 4

⇔ y² = 0

⇔ y = 0

Conclusion:

The two circles intersect at one and only point A(0 , 0).

Clara is 2700 yards far from the home.

In mathematics, yard and inches are two different  units of length. we can say that yard is the one of the measurement of length. Conversion of yard in various quantities is as below:

       1 yard = 36 inches

       1 yard = 3 feet

       1 yard = 0.914 meters

For the statement based question first of all try to find out that what is given in the statement and what we have to find out. Now, try to form the statements in the mathematical notation and then solve the equations by performing certain mathematical and algebra operations according to need.

Now, for the given question :

as, Clara  is 450 yards from the local swimming pool on the map on her phone and the pool is 2/3 inch from her current location.

Therefore, the pool distance is 450 / (2/3) = 675 yards

Now, distance of current location = 4 inches

Thus, Distance from the home = 675 × 4 = 2700 yards

Hence, Clara is 2700 yards far from the home.

Doug entered a canoe race. He rowed 3 1/3 miles in 1/3 hour. What is his average speed in miles per hour?​

If Doug rowed 3 1/3 miles in 1/3 hour the equation is:

3 1/3x = 1/3

multiply both sides by 3:

3(3 1/3x) = 3(1/3)

10x = 1 hour

Doug rowed 10 MPH

Answer:

10 mile per hour

Step-by-step explanation:

3 1/3 mile = 3.3333333333333333333333333333333 mile

1/3 hour = 0.3333333333333333333333333333333333 hour

divide 3.33333333333333333333333 by 0.3333333333333333333333333
= 3.333333333333333333333333333333333 * 1/.33333333333333333333

The value of the car after 6 years will be $7340  .

The Depreciation can be calculated using the formula

A = P( 1 - r/100)ⁿ

where , A = amount , P = principal , r = rate of deprecation , n = time period

In the question ,

it is given that

the value of the car (P) = $28000

rate of deprecation (r) = 20% per year

time period (t) = 6 years

Substituting the values in the Depreciation formula we get ,

Amount = 28000*( 1 - 20/100 )⁶

= 28000*(80/100)⁶

= 28000*(0.80)⁶

= 28000*0.26214

According to given question we have

A number that is larger when positive becomes "more negative," and thus smaller when negative, and vice versa.

Dividing by a negative number is the same as dividing by a positive number and then multiplying by −1. Dividing an inequality by a positive number retains the same inequality. But, multiplying by −1 is the same as switching the signs of the numbers on both sides of the inequality, which reverses the inequality:

a<b⟺−a>−b.

Event correlation is a technique for making sense of a large number of events and pinpointing the few events that are really important in that mass of information. This is accomplished by looking for and analyzing relationships between events.

Event can be defined as a set of outcomes of an experiment. In other words, an event in probability is the subset of the respective sample space. So, what is sample space? The entire possible set of outcomes of a random experiment is the sample space or the individual space of that experiment
