Using the combination formula, it is found that 84 different groups of 6 people are possible from the 9 remaining friends.

The order in which the friends are chosen is not important, hence the combination formula is used to solve this question.

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this problem, 6 friends are chosen from a set of 9, hence:

[tex]C_{9,6} = \frac{9!}{6!3!} = 84[/tex]

84 different groups of 6 people are possible from the 9 remaining friends.

Answer:

ok so use the degrees

Step-by-step explanation:

x should be 8 + 17 and then multiply the 110 degrees by 8 + 17

Answer:

x = 6

The marked angle is 110°

Step-by-step explanation:

See how there are 8 angles in this type of image. The angles either are EQUAL, or they ADD UP TO 180°. It's just two numbers for the degrees of these angles. Four of them are the same and the other four are the same.

In your question the 8 + 17x = 110°

Solve.

Subtract 8.

17x = 102

Divide by 17.

x = 6

If your question says find the measure of the angle it is 110°, if you are to find x, then x = 6.

Jfyi, four of these angles are 110°. The other four are 70°.

Answer:

[tex]y=-\frac{1}{5} x+2[/tex]

Step-by-step explanation:

f(x) = [tex]\frac{5}{x}[/tex]  ⇒ f(x) = [tex]5x^{-1[/tex]

Use the power rule to diferentiate:

f'(x) = [tex]-5x^{-2[/tex]

Plug in the value to differentiate at:

f'(5) = [tex]-5(5)^{-2[/tex] = [tex]-\frac{1}{5}[/tex] = [tex]m[/tex]

Plug into the equation of the tangent line:

[tex]y-f(5)=f'(5)(x-5)[/tex]

[tex]y=f'(5)(x-5)+f(5)[/tex]

[tex]y=-\frac{1}{5} (x-5)+1[/tex]

[tex]y=-\frac{1}{5} x+2[/tex]

Answer:

Range is [tex]\{y|y\neq 1\}[/tex]

Step-by-step explanation:

[tex]f(x)=x+1\\g(x)=\frac{1}{x}\\ \\(f\circ g)(x)=f(g(x))=f(\frac{1}{x})=\frac{1}{x}+1[/tex]

Thus, the range of the composite function is [tex]\{y|y\neq 1\}[/tex], indicated by the horizontal asymptote.

Answer:

the large boxes weigh 40 pounds and the smaller boxes weigh 30 pounds

Step-by-step explanation:

define variables:

b is the weight of large boxes and s is the weight of small boxes. you can create two equations to represent what you know:

b + s = 70 (the weight of one large box and one small box is 70 pounds)

60b+ 55s = 4050 (the total weight of the 60 large boxes and the 55 small boxes is 4050)

then by making one of the equations equal to a variable, you can use substitution to solve.

s = 70 - b

so 60b + 55s = 4050 now becomes:

60b + 55(70 - b) = 4050, and next you solve for b

60b + 3850 - 55b = 4050

5b = 200

b = 40.

now you know that the large boxes weigh 40 pounds. to solve for the small box weight, you plug in b in either equation. i am going to choose the first once since it's fewer steps

b + s = 70 -> 40 + s = 70

s = 30

and now you know that the smaller boxes weigh 30 pounds.

Step-by-step explanation:

Equation of Straight Line in the Form y=mx+c

where m is the Slope and c is the y-intercept.

Answer:

 Slope = -0.400/2.000 = -0.200

 x-intercept = 15/4 = 3.75000

 y-intercept = 15/20 = 3/4 = 0.75000

Step-by-step explanation:

* BE AWARE, THIS ANSWER IS NOT TO BE PLAGERIZED AS IT IS CONSIDERED CHEATING IF THIS IS A TEST OR HOMEWORK QUESTION, MOST LIKELY IT IS* - Purpose is to help understanding of the concept.

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    y-(3/4-1/5*x)=0

STEP 1:

simplify 1/5

Equation at the end of step 1:

y -(3/4-(1/5• x))  = 0

Step 2:

Simplify 3/4

Equation at the end of step 2:

y-)(3/4-x/5)=0

Calculating the Least Common Multiple :

Calculating Multipliers :

3.2    Calculate multipliers for the two fractions

   Denote the Least Common Multiple by  L.C.M

   Denote the Left Multiplier by  Left_M

   Denote the Right Multiplier by  Right_M

   Denote the Left Deniminator by  L_Deno

   Denote the Right Multiplier by  R_Deno

  Left_M = L.C.M / L_Deno = 5

  Right_M = L.C.M / R_Deno = 4

Making Equivalent Fractions :

3.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.   L. Mult. • L. Num.      3 • 5

  ——————————————————  =   —————

        L.C.M              20  

  R. Mult. • R. Num.      x • 4

  ——————————————————  =   —————

        L.C.M              20  

Adding fractions that have a common denominator :

3.4       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

3 • 5 - (x • 4)     15 - 4x

———————————————  =  ———————

      20              20  

Equation at the end of step

:

      (15 - 4x)

 y -  —————————  = 0

         20    

STEP

:

Rewriting the whole as an Equivalent Fraction :

4.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  20  as the denominator :

         y     y • 20

    y =  —  =  ——————

         1       20  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

4.2       Adding up the two equivalent fractions

y • 20 - ((15-4x))     20y + 4x - 15

——————————————————  =  —————————————

        20                  20      

Equation at the end of step

:

 20y + 4x - 15

:

When a fraction equals zero :

5.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 20y+4x-15

 ————————— • 20 = 0 • 20

    20    

Now, on the left hand side, the  20  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  20y+4x-15  = 0

Equation of a Straight Line

5.2     Solve   20y+4x-15  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  20y+4x-15  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 3/4 so this line "cuts" the y axis at y= 0.75000

 y-intercept = 15/20 = 3/4  =  0.75000

Calculate the X-Intercept :

When y = 0 the value of x is 15/4 Our line therefore "cuts" the x axis at x= 3.75000

 x-intercept = 15/4  =  3.75000

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 0.750 and for x=2.000, the value of y is 0.350. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 0.350 - 0.750 = -0.400 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -0.400/2.000 = -0.200

Geometric figure: Straight Line

 Slope = -0.400/2.000 = -0.200

 x-intercept = 15/4 = 3.75000

 y-intercept = 15/20 = 3/4 = 0.75000

The sum of the square of the hypotenuse is equal to the sum of the square of the other sides.The length of the hypotenuse of the triangle is l = √14

The sum of the square of the hypotenuse is equal to the sum of the square of the other sides.

Given that one of the sides is √7, hence;

l^2 = (√7)^2 + (√7)^2
l^2 = 7 + 7
l^2 = 14
l = √14

Hence the length of the hypotenuse of the triangle is l = √14
