Give the name (monomial,

AlladinOne [14]

Answers:

Name = monomial
Degree = 3

====================================

Explanation:

This is a monomial since it's one term. Terms are separated by a plus sign or minus sign. For instance, the expression 2x^3+5x has two terms.

The expression 12x^3 is a cubic monomial, because the exponent is 3. The degree of the monomial is simply the exponent itself. For polynomials, the degree is the largest exponent. This only applies to single variable polynomials.

A girl made a ladybug cage. Her cage has five sides. Each side has a length of 28 centimeters (cm). The cage is 20 cm high. What

Aleksandr [31]

The shape of her Cage's base is Pentagon

The perimeter of the base of the cage is 140 cm

Step-by-step explanation:

Side length of the base of the cage = 28cm

No. of sides the base has = 5

The shape of the cages base is Pentagon as it has 5 sides.

Perimeter= 5(28)

= 140cm

The perimeter of the base of the cage is 140 cm

ABC has vertices at A(5,-1), B(9, -9), and C(4,-1). Write the equation of the line in slope-intercept form that is perpendicular

Gala2k [10]

Answer:

$y=\frac{1}{2}x-3$

Step-by-step explanation:

step 1

Find the slope of AB

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

A(5,-1), B(9, -9)

substitute the values

$m=\frac{-9+1}{9-5}$

$m=\frac{-8}{4}$

$m=-2$

step 2

Find the slope of the line that is perpendicular to AB

we know that

If two lines are perpendicular, their their slopes are opposite reciprocal (the product of their slopes is equal to -1)

we have

$m_A_B=-2$

therefore

The slope of the perpendicular line is

$m=\frac{1}{2}$

step 3

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=\frac{1}{2}$

$C(4,-1)$

substitute

$y+1=\frac{1}{2}(x-4)$

step 4

Convert to slope intercept form

Isolate the variable y

$y+1=\frac{1}{2}x-2\\\\y=\frac{1}{2}x-2-1\\\\y=\frac{1}{2}x-3$
