Domain means the values that can be used as a function's input. Since all real values of x will yield a real value of f(x), the domain is (-infinity, infinity).

What is the factored term form of 2x^3+4x^2-x

Westkost [7]

Answer: $x(2x^2+4x-1)$

Step-by-step explanation:

2x³+4x²-x, first find the Greatest Common Factor (GCF), which is x. To find the GCF, look at what all the numbers have in common, and then see if it has the greatest value. Next factor out the GCF.

$x(\frac{2x^3}{x} + \frac{4x^2}{x}-\frac{x}{x} )$ Simplify each term in the parentheses.

$x(2x^2+4x-1)$

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! :-)

Contact [7]

Answer:

Step-by-step explanation:

Given that latitude and longitude describe locations on the Earth with respect to the equator and prime meridian.

Latitude High Temp

("N)

16 41

30 67

36 63

32 70

11 58

10 61

33 67

30 72

Slope 0.732

Int -21.56266667

Regression line is y = 0.732x-21.563 where x represents the latitude and y high temperature

Since slope = 0.732, we get temp increases by 0.8 degree for 1 degree increasenorth in latitude

Hence option c is right

What is the area of the figure below ?

Airida [17]

Answer:

Step-by-step explanation:

Area of the figure = area of the down triangle + area of trapezium + area of the upper triangle

Down triangle:

Base b = 8 in

Height = 6 in

$Area = \frac{1}{2}bh\\=\frac{1}{2}*8*6\\\\=4*6$

= 24 in²

Trapezium:

bases a = 4 in & b = 6 in

Height h = 5 in

$Area=\frac{(a+b)h}{2}\\\\=\frac{(4+6)*5}{2}\\\\=\frac{10*5}{2}\\\\=5*5$

= 25 in²

Area of the upper triangle:

Base b = 6 in

Height = (8 - 5) = 3 in

$Area=\frac{1}{2}bh\\\\=\frac{1}{2}*6*3\\\\=3*3$

= 9 in²

Area of the figure = 24 + 25 + 9 = 58 in²
