The equation of the known circle is x^2+y^2-4x-4y+4=0, and the two tangents passing through the point (4 , 2) and the point (4/5

Nutka1998 [239]

Answer:

Answer:

4x - 3y = 0

Step-by-step explanation:

The angle between the radius and the

tangent at P is right

The equation of a line in slope-intercept

form is

y = mx + c ( m is the slope and c the y-

intercept)

Rearrange 4y + 3x = 25 into this form

Subtract 3x from both sides

4y = - 3x + 25 ( divide all terms by 4)

y = -- 3 x + 25 + in slope-intercept form

with slope m

Given a line with slope m then the slope

of a line perpendicular to it is

= -

m perpendicular

* = 4, thus

y = 4 x+c+ is the partial equation

To find c substitute P(3, 4) into the partial

equation

4 = 4 +C+c= 4-4 = 0

y = { x + equation of radius in slope-

intercept form

Multiply through by 3

3y = 4x ( subtract 3y from both sides )

4x - 3y = 0 + equation of radius in

standard form

A group of children took part in a study on food allergies. There were about 40,000 children in the group. Nearly 8 percent of t

katovenus [111]

40,000 children
8% has allergies
The rest do not have allergies or 100%-8%
So, 92% do not have allergies.
Who do not have allergies
.92*40,000 = 36,800 children

A 5 gallon can of motor oil costs $28.00. What is the cost of 1 quart of the oil?

Masteriza [31]

There are 4 quarts in a gallon. 4 times 5 is 20 and 28 divided by 20 is 1.4. So the cost of one quart of the oil is $1.40

The graph of the equation x=y2+4is symmetric with respect to which of the following

lyudmila [28]

Answer:

The x-axis

Step-by-step explanation:

The graph of the equation x=y2+4 is symmetric with respect to the x-axis.

To test for symmetry with respect to the x-axis we substitute -y in place of y and simplify the equation. If the resulting equation is identical to original one then the function is symmetric with respect to the x-axis;

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

which is identical to the original equation
