Answer:

The graph has a greater rate of change and y-intercept.

Slope is 3/4 and y-intercept is about -1 which is greater than the one in the equation.

Find the measure of each angle

Nesterboy [21]

Let's solve this problem step-by-step.

To begin with, it is important to establish the following formula:

Angle sum of all triangles = 180°

Using this formula as well as the values of two out of three of the angles given, we can identify the value of the unknown angle as displayed as the following:

Let the unknown angle = x

Make (x) the subject as displayed as the following:

Angle sum of all triangles = 180°
180 = x + 63 + 59
x = 180 - 63 - 59
x = 58°

Therefore, the measure of each of the angles is as follows:

63°
59°
58°

you work for a telecommunications company and need to analyze the outcome of a proposed new cell tower project. cell phone radio

umka21 [38]

Answer:

The equations describing the area which each tower covers are given as

Tower A : $x^{2} + y^{2} = 16$

Tower B : $(x - 5)^{2} + (y - 4)^{2} = 9$

Tower C : $(x - 4)^{2} + (y + 4)^{2} = 25$

Step-by-step solution:

Cell phone radio towers broadcast a cell phone signal in circular pattern

Tower A at Adele Acres have position co-ordinates as (0,0) and a coverage radius of 4 ml. So, the area which it covers is given by the equation,

$x^{2} + y^{2} = 16$ -------------------------------(1)

Tower B at Brown Lake have position co-ordinates as (5,4) and a coverage radius of 3 ml. So, the area which it covers is given by the equation,

$(x - 5)^{2} + (y - 4)^{2} = 9$ -------------------------------(2)

Tower C at Cady City have position co-ordinates as (4,-4) and a coverage radius of 5 ml. So, the area which it covers is given by the equation,

$(x - 4)^{2} + (y + 4)^{2} = 25$ -------------------------------(2)

Consider the spiral given by c(t) = (e2t cos(2t), e2t sin(2t)). Show that the angle between c and c' is constant. c'(t) = _____L

Tcecarenko [31]

Answer:

angle is 45° which is constant

Step-by-step explanation:

We use formula for two vectors <u>a </u>and <u>b</u> to calculate angle θ between them by formula

cos θ = <u>a .</u> <u>b</u> / magnitude of <u>a </u> × magnitude of <u>b</u>
