Answer:

Option (D)

Step-by-step explanation:

Given expression is,

x³ × 3 ÷ \frac{2}{9} + 9x - (7 - 6x)

By substituting x = \frac{2}{3},

(\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-[7-6(\frac{2}{3})]

By using rule PEMDAS,

P - Parenthesis

E - Exponent

M - Multiplication

D - Division

A - Addition

S - Subtraction

=(\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-[7-4]

= (\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-3

= \frac{8}{27}\times 3 \div \frac{2}{9}+6-3

= \frac{8}{9}\div \frac{2}{9}+6-3

= \frac{8}{9}\times \frac{9}{2}+6-3

= 4 + 6 - 3

= 7

Option (D) is the answer.

The table represents a quadratic function. Write an equation of the function in standard form.
kakasveta [241]

The equation of the quadratic function in standard form as required in the task content is; f(x) = -x² + 12x - 43.

<h3>Standard form equation of a quadratic function.</h3>

It follows from the task content that the standard form equation of the quadratic function is to.be determined.

Since the standard form equation can be derived from the vertex form equation as follows;

f(x) = a (x - h)² + k

f(x) = a (x - 6)² - 7

Hence, to find the value of a, Substitute x = 8 and f(x) = -11 so that we have;

-11 = a (8 - 6)² - 7

-11 = 4a - 7

4a = -4

a = -1.

Hence, the equation in vertex form is; f(x) = -1 (x -6)² - 7 and when expressed in standard form we have;

f(x) = -1(x² - 12x + 36) - 7

f(x) = -x² + 12x - 43

Therefore, the required equation in standard form is; f(x) = -x² + 12x - 43.

A field is in the shape of a rectangle 5/6 mile long and 3/4 mile wide. What is the area of the field? *
Lynna [10]

Area = length x width

Area = 5/6 x 3/4

= (5x3) / (6x4)

= 15/24

= 5/8 square miles
