Answer:

1) 36, 2) 14, 3) 19, 4) 18, 5) 3, 6) 117

Step-by-step explanation:

1) 6(7) - 3(2) 2) (7)(4)/2 3) (7) + |2(7) - (2)| 4) 6(5) - 4(3) 5) [(4) + (5)]/3

42 - 6 28/2 7 + |14 - 2| 30 - 12 9/3

36 14 7 + 12 18 3

6) (4) + [(5)^3 + (3)] - 15

4 + (125 + 3) - 15

4 + 128 - 15

132 - 15

The length of a iron-sheet and copper-sheet is 672 cm and 960 cm respectively.what will be the length of the highest piece of eq

marissa [1.9K]

In order to calculate the length of highest piece, You need to calculate the Greatest common divisor of 672 & 960 which is 96

So, the length of highest piece would be 96 cm

Now, Number of pieces of Iron-sheet = 672 / 96 = 7
Number of pieces of Copper-sheet = 960 / 96 = 10

Hope this helps!

Someone help yaaa girl out!!! Fr need help ASAP.

Daniel [21]

z=24 degrees. To explain, you can solve for x by making the equation 2x+48=180 since 180 degrees is the angle of a straight line. Once you solve for x, you add that number to 90. Finally, subtract that number from 180 to get z. You subtract from 180 because a triangle's total angle sum is always 180

Describe how the graph of y = x2 can be transformed to the graph of the given equation.

Vikki [24]

1.Describe how the graph of y = x2 can be transformed to the graph of the given equation.

y = (x+17)2

Shift the graph of y = x2 left 17 units.

2.Describe how the graph of y= x2 can be transformed to the graph of the given equation.

y = (x-4)2-8

Shift the graph of y = x2 right 4 units and then down 8 units.

.Describe how to transform the graph of f into the graph of g.

f(x) = x2 and g(x) = -(-x)2

Reflect the graph of f across the y-axis and then reflect across the x-axis.

Question 4 (Multiple Choice Worth 2 points)

Describe how the graph of y= x2 can be transformed to the graph of the given equation.

y = x2 + 8

Shift the graph of y = x2 up 8 units.

Question 5 (Essay Worth 2 points)

Describe the transformation of the graph of f into the graph of g as either a horizontal or vertical stretch.
f as a function of x is equal to the square root of x and g as a function of x is equal to 8 times the square root of x

f(x) = √x, g(x) = 8√x

vertical stretch factor 8

How can you determine if you need to use a combination or permutation to count the number of outcomes? Which will usually have m

Nadya [2.5K]

Answer with Step-by-step explanation:

Permutation : It is an arrangement of r elements out of n elements.

Combination : it is a selection of r element out of n elements .

Suppose we have a set

S={1,2,3}

If two elements are taken at a time then

Using permutation formula

Total number of outcomes= $3P_2$

Total number of outcomes= $\frac{3!}{(3-2)!}$

Total number of outcomes=3!= $3\times 2\times1=6$

Using combination formula

$\binom{n}{r}=\frac{n!}{r!(n-r)!}$

Total number of outcomes= $\binom{3}{2}=\frac{3!}{2!1!}$

Total number of outcomes= $\frac{3\times2!}{2!}$

Hence, total number of outcomes=3

Total number of outcomes determined by permutation have more outcomes.

Because permutation is an arrangement of elements therefore, it consider order of arrangement of element but combination is a selection of elements it does no consider order of elements

Arrangements of two elements out of 3 elements

{1,2},{2,3},{2,1},{3,2},{1,3},{3,1}

By using combination if two elements taken at a time then combination

{1,2},{2,3},{1,3}
