Answer:

11.66

Step-by-step explanation:

Pythagorean theorem: a^2+b^2=c^2

6^2+10^2=c^2

36+100= c^2

sqrt(136)= sqrt(c)

c= 11.66

Answer:

x is 24 degrees

Answer:

x = 24

Step-by-step explanation:

I'm 8 years old and I know how to do this.

The sum of interior angles of a quadrilateral is 360°

The sum of a supplementary angle is 180°

180 - 111 = 69

94 + 41 + 69 + a = 360

204 + a = 360

a = 156

156 + x = 180

x = 24

Step-by-step explanation:

Answer:

17 cm

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 +b^2 = c^2  where a and b are the legs and c is the hypotenuse

8^2 + 15^2 =c^2

64+225 = c^2

289 = c^2

Take the square root of each side

sqrt(289) = sqrt(c^2)

17 = c

Answer:

The hypotenuse is 17cm

Step-by-step explanation:

Pythagoras theorem is :   [tex]a^{2} +b^{2} =c^{2}[/tex]

To work out the hypotenuse of this triangle you would first need to know Pythagoras theorem. The theorem states that [tex]a^{2} +b^{2} =c^{2}[/tex]. A and B are the 2 lengths given in this question and c is the hypotenuse.

The first step in working out the hypotenuse is to square the base of 8, this gives you 64.

Then you would need to square the height of 15, this gives you 225. This is because we are substituting the values into a and b.

Then the next step is to add the values of 64 and 225, this gives you 289.

The final step is to root the value of 289, which gives you 17cm. This is because as c is the hypotenuse while the value worked out is c squared and so to work out c you would have to root it.

1) Square the base of 8cm.

[tex]8^{2} =64[/tex]

2) Square the height of 15cm.

[tex]15^{2} =225[/tex]

3) Add 64 and 225.

[tex]64+225=289[/tex]

4) Root the value of 289.

[tex]\sqrt{289}= 17cm[/tex]

Answer:

The value of x is 56°

Step-by-step explanation:

Given that opposite angles in a cyclic quadrilateral is add up to 180°. So in order to find x, you have to write an expression in terms of x :

[tex]97 + x + 27 = 180[/tex]

[tex]x + 124 = 180[/tex]

Next you have to solve it by substracting 124 to both sides :

[tex]x + 124 - 124 = 180 - 124[/tex]

[tex]x = 56[/tex]

Answer:

48 km/h.

This is because 1200/25 is 48.

Answer:

49 cm²

Step-by-step explanation:

The area for a square is Area = length x width, and if the square name tag is 7cm long on "each side", that means that both the length and the width are 7cm.

Plug this into the formula to get A = 7cm x 7cm.

This can be simplified to A = 49cm².

Answer: 49 cm^2

Step-by-step explanation:

7 x 7 = 49

Answer:

The Pythagorean theorem works only on right triangles. Also it is used to find the hypotenuse when you know 2 other sides.

Step-by-step explanation:

Answer: The Pythagorean Theorem is a formula used to find the hypotenuse (the value of C2).

Step-by-step explanation: That formula is A2 + B2 = C2. Right Triangles are the only triangles that relate to the Pythagorean Theorem.

Answer:

GCF = x+3

Step-by-step explanation:

(6x+18)/(x^2-x-12) = 6 (x+3)/(x^2 +3x - 4x -12)

                            = 6(x+3)/( x(x+3) - 4(x+3) )

                            = 6(x+3)/( (x-4)(x+3) )

The greatest common factor (GCF) of the numerator and denominator of the rational expression [tex]\frac{(6x+18)}{(x^2-x-12)}[/tex]  is (x + 3) .

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.  

According to the question

The rational expression :

[tex]\frac{(6x+18)}{(x^2-x-12)}[/tex]

The greatest common factor (GCF)  of the numerator and denominator

Step 1 : We take out factors of numerator

(6x+18) = 6 (x + 3)

Step 2 : Then we take out  factors of denominator

[tex](x^2-x-12)[/tex] = x² - (4-3)x - 12

                    =  x² - 4x + 3x - 12

                    =  x (x - 4) + 3(x - 4)

                    = (x + 3) (x - 4)  

Now , The greatest common factor (GCF)  of the numerator and denominator is  (x + 3)  which is present in both .

Hence, the greatest common factor (GCF) of the numerator and denominator of the rational expression [tex]\frac{(6x+18)}{(x^2-x-12)}[/tex]  is (x + 3) .

Answer:

2:4  means one part is 2/(2+4)=1/3 of AB and the other part is 2/3 of AB

Step-by-step explanation:

Add  1/3 of the distance from -2 to 4.  (1/3)(4+2)=2.  -2+2=0   The x coordinate is 0

Subtract 1/3 of the distance from 6 to -6,  (1/3)6+6)=4   6-4=2  The y coordinate is 2

The point is (0,2)

Check the answer

distance from (-2,6) to (0,2)   is square root of (-2)^2 + (4)^2 = sqr20 = 2(5)^2

distance from (0,2) to (4,-6)  is square root of (4)^2 +(8)^2 = sqr80 = 4(5)^2

First distance is half the 2nd distance,  so the point divides AB into 2 parts in a ratio of 2:4

Answer:

The exponential funtion is "height(n) = 77*(0.9925)^n". After 15 years he is 68.7778 inches.

Step-by-step explanation:

Since Tom's initial height is 77 inches. After one year:

height(1) = 77*(1 - 0.0075) = 77*0.9925

After two years:

height(2) = height(1)*(0.9925) = 77*0.9925*(0.9925) = 77*(0.9925)²

After three years:

height(3) = height(2)*0.9925 = 77*(0.9925)²*0.9925 = 77*(0.9925)³

And so on, therefore the expression that represents his height is:

height(n) = 77*(0.9925)^n

Where n is the number of elapsed years. For 15 years we have:

height(15) = 77*(0.9925)^(15) = 68.7778 inches

The exponential funtion is "height(n) = 77*(0.9925)^n". After 15 years he is 68.7778 inches.

What are the choices??

Step-by-step explanation:

Answer:

Step-by-step explanation:

We cannot factor this function out which tells us that there are no zeros. The graph backs this up because we can see that there are none. The easiest way to graph this would start by plugging in points and making a table for yourself.

Lets start by plugging in -1.

(-1)^2-2(-1)+3 =6, this means we have a point at (-1,6).

Now lets plug in 0.

(0)^2-2(0)+3= 3 (0,3)

For plugging in 1

(1)^2-2(1)+3=2 (1,2) (this happens to be the vertex)

And lastly lets plug in 2

(2)^2-2(2)+3=3 (2,3)

Depending on how many points are needed, keep plugging in numbers like we did above.
