Answer:

D

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write expression

[tex](\frac{7}{2}-\frac{1}{3} )(-2)^2+\frac{1}{2}[/tex]

Step 2: Evaluate

Answer:

13 1/6

Step-by-step explanation:

Follow PEMDAS:

(7/2-1/3) * (-2)^2 +1/2

P: parenthesis... 7/2 - 1/3 is 19/6

then you do E: exponents... (-2)^2 is basically -2 * -2 which a negative multiplied by a negative is a positive so its 4.

19/6 * 4+1/2

PE M DAS... M: multiply... 19/6 *4 is 38/3 which simplifies to 12 2/3

Lastly you add 12 2/3 with 1/2 and you get 13 1/6

Answer:

1.917

Step-by-step explanation:

The difference between 4.091 and 2.174 will be;

⇒ 1.917

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

The numbers are,

⇒ 4.091 and 2.174

Now,

Since, The numbers are,

⇒ 4.091 and 2.174

Hence, The difference the number 4.091 and 2.174 is,

⇒ 4.091 - 2.174

⇒ 1.917

Thus, The difference between 4.091 and 2.174 = 1.917

Answer:

A

Step-by-step explanation:

Because subtraction and addition are alike just how multiplication and division are.

The inverse of f(x) is (x+6)/5, the correct option is A

Suppose that the given function is

[tex]f:X\rightarrow Y[/tex]

Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is

[tex]f^{-1}: Y \rightarrow X[/tex]

such that:

[tex]\forall \: x \in X : f(x) \in Y, \exists \: y \in Y : f^{-1}(y) \in X[/tex]

It simply means, inverse of 'f' is undo operator, that takes back the effect of 'f'

Given;

f(x) = 5x - 6

f^-1 (x ) = x+6/5

Let, y = f(x) and rearrange making x the subject;

y = 5x - 6 ( add 6 to both sides )

y + 6 = 5x ( divide both sides by 5 )

x = (y+6)/5

Change y back into terms of x

x  = (x+6)/5

Therefore, the answer in inverse will be (x+6)/5

Answer:

Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder. So, the formula for the lateral surface area of a right cone is L. S. A=πrl , where l is the slant height of the cone .

Answer:   x = 6

Step-by-step explanation:

Angles 1 and 8 are alternate exterior angles, so they are equal.

so you can create an equation to solve for x

12x−20 = 2x+40  Subtract 2x from both sides. Add 20 to both sides

10x = 60

x = 6

if you need the  m∠1, Substitute 6 for x.  (2x+40)°  2(6) +40= 12+40 m∠1= 52°

m∠8=(12x−20)°   12(6) - 20 = 72-20  m∠8 = 52°

Answer:

Step-by-step explanation:

Another way to state it is to say that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. If you put the two shortest sides end to end, they have to be longer than the longest side to be able to angle up to form a triangle.

Answer:

3. 3, 5, 7

4. 1.1, 2.2, 3.2

5. 13, 5, 12

7. 5, 4, 3

8. 4, 4, 3

Step-by-step explanation:

In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

1. 19, 16, 3

16 + 3 = 19

No triangle

2. 1, 2, 3

1 + 2 = 3

No triangle.

3. 3, 5, 7

3 + 5 = 8 > 7

3 + 7 = 10 > 5

7 + 5 = 12 > 3

Triangle

4. 1.1, 2.2, 3.2

1.1 + 2.2 = 3.3 > 3.2

2.2 + 3.2 = 5.4 > 1.1

1.1 + 3.2 = 4.3 > 2.2

Triangle

5. 13, 5, 12

13 + 5 = 18 >12

5 + 12 = 17 > 13

13 + 12 = 25 > 5

Triangle

6. 1, 7, 8

1 + 7 = 8

No triangle.

7. 5, 4, 3

5 + 4 = 9 > 3

4 + 3 = 7 > 5

5 + 3 = 8 > 4

8. 4, 4, 3

4 + 4 = 8 > 3

4 + 3 = 7 > 4

Triangle.

The coordinates of B is (-6, -7)

The given parameters are

A = (4, -3)

M = (-1, -5)

The midpoint of a line is calculated as

M = 1/2(x1 + x2, y1 + y2)

So, we have

(-1, -5) = 1/2 * (4 + x, -3 + y)

This gives

(-2, -10) = (4 + x, -3 + y)

Solve for x and y

4 + x = -2

-3 + y =-10

Evaluate

x = -6 and y = -7

Hence, the coordinates of B is (-6, -7)
