Answer:

When asked to write an equation, you need to know two things – slope (m) and y-intercept (b).

Or

The Standard Form for a linear equation in two variables, x, and y, is usually given as Ax + By = C where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.

Answer:

Slope and y intercept.

Step-by-step explanation:

This is necassary to write the equation of a line in y=mx+b

m is where the slope goes, and b is the y intercept.

Alternatively, you could also write the equation for a line with a point on the line and the slope.

You would then write it in point slope formula:

y-y1=m(x-x1)

This can later be converted into slope intercept form.

Question 2 An exponential model y = a.6 passes through the points (0,9) and (3,243). What are the values of a and b?​
weqwewe [10]

Answer:

a = 9, b = 3

Step-by-step explanation:

The exponential function is

y = a b^{x}

Find a and b by using the points it passes through

Using (0, 9 ) then

9 = a b^{0} ( b^{0} = 1 )

a = 9

y = 9 b^{x}

Using (3, 243 ) then

243 = 9b³ ( divide both sides by 9 )

27 = b³ ( take the cube root of both sides )

b = \sqrt[3]{27} = 3

y = 9(3)^{x} ← exponential equation

A hemisphere has a diameter of 48 inches. What is the volume of the
ss7ja [257]

Answer:

9,216π or 28,938.2 meters³

Step-by-step explanation:

Given: diameter 48 inches

Radius 24 inches

Note:

Volume of hemisphere = volume of sphere / 2

Volume of hemisphere = 1/2 • 4/3 • πr³

= 1/2• 4/3×π×24³

= 1/2•18432π

= 9,216π

= 28,938.2 meters³

Segments cf, eb, and ad are medians of triangle ace. cf = 3.6 m. what is the length of segment cg?
Vaselesa [24]
Assuming g is the centroid, it is 2/3 of the length of cf from point c.
  cg = (2/3)cf = (2/3)3.6 m
  cg = 2.4 m
