Answer:

Option A is correct

Step-by-step explanation:

We have been given four equations and we need to tell which one of them is quadratic

Case1:

$6(x+2)^2+8(x+2)+1$

In this we will use the formula $(a+b)^2=a^2+b^2+2ab$

Here, a=x and b=2

The equation will become $6(x^2+2^2+4x)+8x+16+1$

Hence, after simplification equation will become

$6x^2+24+24x+8x+16+1$

$6x^2+32x+41$ which is a quadratic equation because quadratic equation is the equation is the equation which has degree 2.

In this equation degree is 2 hence, quadratic

Case2:

$6x^4+7x^2-3$ is not quadratic since, degree in this equation is 4 not 2

Hence, biquadratic not quadratic

Case3:

$5x^6+x^4+12$ is not a quadratic equation since, degree in this equation is 6.

Hence, not quadratic

Case4:

$x^9+x^3-10$ is not quadratic since, degree in this equation is 9

Hence, not quadratic

Therefore, Option A is correct

A quadratic equation is a polynomial with an order of two. Its general form is ax² + bx + c = 0. From the choices given, the first option seems to be the quadratic equation. Simplifying the equation gives 6x² + 18x + 27 = 0.

Which is bigger 0.125 or 0.15

Answers

0.125 is smaller, and 0.15 is bigger.

Here's how u tell:
The largest place in a decimal is the tens place, first u check the tens place of the decimals. OK, they are both 1. Then you move to hundredths place, see here is where's the catch. One is 2, and one is 5. So you go for the one with the five bc thats bigger.

so, 0.15 is bigger

0.125 is smaller than 0.150.150=0.150.150-0.125=0.025 there is a difference0.125-0.150= - number

For a button to fit through its buttonhole the hole needs to be size of the buttons diameter. What size butte hole is needed for a button with a circumference of 7.38 centimeters (use the value of 3.14 to represent pi.) HELP ME PLEAS

Answers

circumference = 2πr

diameter = 2 r

7.38 = 2 r (3.14)

7.38/3.14 = 2 r

2 r = 2.35 cen.

diameter needs to be 2.35 cen.

Answer:

$\huge\boxed{V = 359.01 mm^(3) }$

Use the formula V = 1/3(bh) to solve for the volume of the cone where b = πr² where π ≈ 3.14:

Find the area of the base:

b = π(7)²

b = 49π

b = 153.86 mm²

Find the volume:

V = 1/3(153.86 · 7)

V = 1/3(1077.02)

V = 359.006 ≈ 359.01 mm³.
