Answer

See graph

Step-by-step explanation

The given line segment passes through the point (-5,7) and  (4,-3).

We plot this points and draw a straight line to them to obtain the blue line as shown in the

attachment.

The slope of this line segment is given by the formula

m=\frac{y_2-y_1}{x_2-x_1}

This implies that,

m=\frac{7--3}{-5-4}

m=-\frac{10}{9}

The equation of this line is given by the formula,

y-y_1=m(x-x_1)

y+3=-\frac{10}{9}(x-4)

9y+27=-10(x-4)

9y+27=-10x+40

9y=-10x+13

We now find the inverse by interchanging x and y.

9x=-10y+13

We now make y the subject,

9x-13=-10y

y=-\frac{9}{10}x+\frac{13}{10}

We now plot some points.

When

x=7

y=-\frac{9}{10}\times 7+\frac{13}{10}

y=-\frac{50}{10}=-5

This gives the ordered pair

(7,-5)

Also when

x=-3

y=-\frac{9}{10}\times -3+\frac{13}{10}

y=\frac{40}{10}=4

This gives the ordered pairs,

(-3,4)

We plot these points too and draw a straight line through them to get the red line in the attachment.

A person x inches tall has a pulse rate of y beats per​ minute, as given approximately by yequals600 x Superscript negative 1 di
tankabanditka [31]

Answer:

a) 5.13beats/min

b) 2.82 beats/min

Step-by-step explanation:

Given the pulse rate of a person modelled by the equation y = 600x^-1/3 for 30≤x≤75

If the height is 39inches, the instantaneous rate of change of pulse rate for the heights will be expressed as;

y = 600(39)^-1/3

y = {600(1/39)}/3

y = 600/39×3

y = 600/117

y ≈ 5.13beats/min

The instantaneous rate for a 39 inches tall person is 5.13 beats per min

b) For a 71inches tall person, the beat rate will be expressed as;

y = 600(71)^-1/3

y = {600(1/71)}/3

y = 600/71×3

y = 600/213

y ≈ 2.82 beats per minute

The instantaneous rate for a 71 inches tall person is 2.82 beats per min

Find the center and radius of x^2 – 18x + y^2 -10y = -6. part two write x2 – 18x + y2 -10y = -6 in standard form
Aleks04 [339]

Answer:

see explanation

Step-by-step explanation:

I will begin with part two, first.

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius.

Given

x² - 18x + y² - 10y = - 6

Using the method of completing the square

add ( half the coefficient of the x/ y terms )² to both sides

x² + 2(- 9)x + 81 + y² + 2(- 5)y + 25 = - 6 + 81 + 25, that is

(x - 9)² + (y - 5)² = 100 ← in standard form

with centre = (9, 5 ) and r = \sqrt{100} = 10
