For the following quadratic function, find the axis of symmetry, the vertex and the y-intercept. y = x^2 + 8x + 12 axis of symmetry: x = 8; vertex: (8,140); y-intercept: 8
axis of symmetry: x = -8; vertex (-8,12); y-intercept: -8
axis of symmetry: x = 4; vertex: (4,60); y-intercept: 12
axis of symmetry: x = -4; vertex: (-4,-4); y-intercept: 12

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
