Answer:

Discriminant = -92

the equation has no distinct real numbers

Step-by-step explanation:

Given the function f(x) = 4x^2 + 2x + 6 where;

a = 4, b = 2 and c= 6

The discriminant is expessed as D = b^2 - 4ac

Substitute;

D = 2^2 - 4(4)(6)

D = 4 - 96

D = -92

Hence the discriminant is -92.

Since the discriminant is less than zero i.e D< 0, this shows that the zeros of the equation are not real but complex numbers. Hence, the equation has no distinct real numbers

The subsets of the real numbers can be represented in a Venn diagram as shown. To which subset of real numbers does −2π belong?
Alecsey [184]

Answer:

D

Step-by-step explanation:

Whole numbers are the basic counting numbers: 0,\ 1,\ 2,\ 3,\ 4, \....

Integers are whole numbers and negative numbers: ...,\ -2,\ -1,\ 0,\ 1,\ 2,\ ...

Rational numbers are all fractions \frac{m}{n}, where m is an integer and n is a natural number.

Irrational numbers are all real numbers that are not rational.

Number \pi is irrational number (it is not counting number, so it is not whole number, not integer number), it cannot be represented as a fraction, so it is not rational number, thus this number is irrational number.

The product of integer number -2 by irrational number \pi is irrational number -2\pi

Correct option - option D

What is the surface area of this design?<br> A.150in2<br> B.197in2<br> C.210in2<br> D.127in2
ANEK [815]

Answer:

197 in ^2 (answer B of the list)

Step-by-step explanation:

Notice that this figure has a total of 6 faces, four of which are rectangles (whose area is calculated as "base times height") and two trapezoids (whose area is (B+b)H/2 ).

The total surface area is therefore the addition of these six areas:

Rectangles:

5 in x 5 in = 25 in^2

5 in x 5 in = 25 in^2

5 in x 6.4 in = 32 in^2

9 in x 5 in = 45 in^2

Trapezoids:

Two of equal dimensions: B = 9 in, b = 5 in, H = 5 in

2 * (9 in + 5 in) 5 in /2 = 70 in^2

Which gives a total of  (25 + 25 + 32+45 + 70) in^2 = 197 in^2

This agrees with answer B of he provided list.

I need help with number 16 please.
Kruka [31]
The graph is misleading because the sizes compared to the percentages are off. a more appropriate way to show the data would be with a bar graph.
Hope this helps!
