<u>The following are the evaluation steps in order for the 8 \times 3 \div\left(4^{2}-13\right)+5^{2}+4 \times 3 given expression:</u>

Step 1: First perform exponentiation inside parentheses

             4^{2}

Step 2: Next, evaluate the contents of parentheses

               (16 – 13)

Step 3: Before any multiplication or division, exponentiation outside parentheses should be done.

               5^{2}

Step 4: Perform multiplication and division from left to right

                8 \times 3

Step 5: Perform multiplication and division from left to right

              \frac{24}{3}

Step 6: Perform multiplication and division from left to right

                4 \times 3

Step 7: After all the multiplication and division, addition should be performed from left to right

                  (8 + 25)  

Step 8: Perform addition from left to right

                    (33 + 12)

Use the Venn diagram to list the set of elements of A ∩ B in roster form.
artcher [175]

Answer:

A. {e, h}

Step-by-step explanation:

In a Venn diagram, the set of elements in any intersection can simply be visualised. The elements contained in the region where the circles representing different sets overlap, are the set of elements of intersection.

In the Venn diagram given, the set of elements contained in the region where the circles representing A and B overlap are {e, h}.

{e, h} is common to both set A and set B.

Y = x^2+ 7x - 5 can be written in the form y = (x + a)^2+b
BARSIC [14]

Answer:

see explanation

Step-by-step explanation:

The equation of a parabola in vertex form is

y = (x - h)² + k (h, k) are the coordinates of the vertex

Given y = x² + 7x - 5

To express in vertex form use the method of completing the square

add/subtract ( half the coefficient of the x- term )²

y = x² + 2( \frac{7}{2} )x +\frac{49}{4} - \frac{49}{4} - 5

y = (x + \frac{7}{2} )² - \frac{49}{4} - \frac{20}{4}

y = (x + \frac{7}{2} )² - \frac{69}{4}

Hence

a = \frac{7}{2} and b = - \frac{69}{4}
