What is the square root of 18 plus the square root of 2? And is it rational or irrational?
​

Answer:

(½x+½y)²=6

Step-by-step explanation:

x^2 + y^2 = 14, xy=5

(A+B)^2=A^2 +2AB+B^2... (*)

(1/2x+1/2y)^2 =(*)

(1/2x)^2 +2(1/2x)(1/2y)+(1/2y)^2 =

1/4x^2 +1/2xy+1/4y^2=

1/4(x^2 +y^2) +1/2(xy)=

1/4*14+1/2*5=

14/4+5/2=

14/4+10/4=

24/4=6

let me know if I'm wrong.

( 1/2x +1/2y)²

= { ( x + y )/ 2xy }²

= ( x² + 2xy + y² )/4(xy)² —(1)

As we know that x² + y² = 14 — (2)

and xy = 5 —(3)

So, substitute the value of equation 2 and 3 in equation 1,

= ( x² + 2xy + y²)/4(xy)²

=( 14 + 2*5)/(4*5²)

= 24/(4*25)

= 6/25.

Answer:

c

Step-by-step explanation:

The solution is, C. AB = WX, must to be true to prove AABC= AWXY by the AAS theorem.

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

here, we have,

We are given,

Triangles ABC and WXY having ∠A=∠W and ∠B=∠X

Now, it is give that the triangles hold AAS theorem.

Since, we already have two corresponding angles equal i.e. ∠A=∠W and ∠B=∠X.

So, by AAS Theorem, the corresponding sides between these angles must be  equal.

Thus, we have, AB = WX.

Hence, option C is correct. C. AB = WX, must to be true to prove AABC= AWXY by the AAS theorem.

The number of strawberry ice cream cones the shop sells that Saturday is 9 ice cream.

calculation:-

An ice cream shop sells ice cream cones with exactly 1 of 3 ice cream flavors in the cone.

let a number of strawberry ice cream this shop sold on satrday=X

  number of vanilla ice cream shops sold = X+2

       number of Chocolate ice cream shops sold = X+2+11

Total number of icecream sold on Saturday =42

       ⇒ X+ X+2+ X+2+11 = 42

      ⇒ 3X + 15 =42

      ⇒   3X = 27

      ⇒X = 27/3

       ⇒   X = 9

Answer:

Step-by-step explanation:

( x1, y1 ) = ( - 4, - 2 )

Here,

x1 = - 4

y1 = - 2

( x2, y2 ) = ( - 4, 22 )

Here,

x2 = - 4

y2 = 22

Formula : -

Slope = ( y2 - y1 ) / ( x2 - x1 )

Slope

= ( 22 - ( - 2 ) ) / ( - 4 - ( - 4 ) )

= ( 22 + 2 ) / ( - 4 + 4 )

= 24 / 0

= 0

Answer:

...probably

Step-by-step explanation:

since it's square units and this is a right triangle

area = (width * height) / 2

area = 6 * 3 / 2

area = 18 / 2

area = 9 square units²

Answer:

9 [tex]units^{2}[/tex]

Step-by-step explanation:

The formula to find the area of a triangle is [tex]A=\frac{1}{2}b*h[/tex] where b is the base or bottom of the triangle and h is the height of the triangle.

The base of the triangle in the picture is 6 units.

The height of the triangle in the picture is 3 units.

Substituting these values into the area formula:

[tex]A=\frac{1}{2}(6*3)=\frac{1}{2}(18)=9[/tex]

So the area of the triangle is 9 [tex]units^{2}[/tex]

Answer:

I'll assume "position 7" refers to distance and not to the order of other people.  

Step-by-step explanation:

We want an equation of the form y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).  We can assume that "claps" is a new measure of distance.  0 claps is the finish.

Let's express the information provided in point format.

"At 2 claps, Joe is in position 7"  is (2,7)  2 is the distance (claps) and 7 is the time (minutes)

And we can say the rate is also the slope of a line.  "rate of 3 claps per minute" is 3c/m, where c is claps and m is minutes.

We can start a line equation by stating y = 3x + b, where we're using the rate, 3 c/m, as the slope, m.

We need to determine the value of b.  We can use the given point (2,7) and solve for m:

y = 3x + b

7 = 3*(2) + b

b = 1

The equation becomes y = 3x + 1

y is the distance in claps and x is the time in minutes.

At a time of 2 claps he is at position of 7.  b = 1 means he started 1 clap further from the finish at 0 claps.

To find the time required to reach the finish, we need to know the total distance, in claps.

Step-by-step explanation:

hopefully im right

due to my knowledge its 75 because it is.

Step-by-step explanation:

first I thought the angles at Q and P are right angles (90 degrees). but the last part tells me they are not.

so, all the "perpendicular" answers are out.

answer 1 and 2 are all correct but I would pick 2, because it had the most detail that's true.

and since these 2 lines are parallel, the must have the same angles with the crossing line.

therefore, when the angle RQS is 75 degrees, then the angle TPU is also 75 degrees.

Answer:

it will take the certain particle 15/4 (unit of time) to reach 30 km/hr

Input 30 as for y and solve the equation.

Step-by-step explanation:

Since y is kilometers per hour and the question is asking for how long it takes for a certain particle to reach 30 km/hr, you input 30 for y and solve for x.

-4x + y = 15

-4x + (30) = 15

subtract 30 from both sides

-4x = -15

divide -4 from both sides

x = 15/4

it will take the certain particle 15/4 (unit of time) to reach 30 km/hr

Answer:

To overcome such type of real world problems we use union. Unlike structures union occupies single memory location to store all its members. So, unions are helpful when you want to store value in single member from a set of members. Size of union is defined according to size of largest member data type.

Step-by-step explanation:

In union, all members share the same memory location. For example in the following C program, both x and y share the same location. If we change x, we can see the changes being reflected in y. #include <stdio.h> // Declaration of union is same as structures.

Answer:

x = + 14.88 km

Step-by-step explanation:

Let's solve for x using the Pythagorean Theorem.  

The length of the hypotenuse is 15.8 km; that of the shorter leg is 5.3 km.

Since a² + b² = c², we get:

(5.3 km)² + x² = (15.8 km)²

Solving for x², we obtain (15.8 km)² - (5.3 km)² = 249.64 km² - 28.09 km²

The last expression returns the value 221.55 km² for x²

Taking the square root of both sides, we get x = + 14.88 km
