Answer:

(a) 0.05 minutes per calorie burned

(b) Slope = 20

Step-by-step explanation:

(a) If 200 calories are burned in 10 minutes...then what about 1 calorie

; 1/200 × 10 = 0.05 minutes

(b) Slope of the graph...;just take any two points on the graph...which are (10;200) and (20;400)

Slope = (400 - 200) ÷ (20 - 10)

;Slope = 200 ÷ 10

;Slope = 20

What is the distance from the point (3,8) to the point (7,-6)?

oksano4ka [1.4K]

Answer: Distance is 14.6

Step-by-step explanation:

$d = √((x2-x1)2 + (y2-y1)2)$

$(x2-x1) = (7 - 3) = 4$

$(y2-y1) = (-6 - 8) = -14$

add it all together

$(4)2 + (-14)2 = 16 + 196 = 212$

Square 212

$\sqrt{212} =14.5602$

round to the nearest tenth

=14.6

It is given that y is directly proportional to x. When x = 3, y = 18. (a) Find the equation connecting x and y. (b) Hence, find

guapka [62]

Answer:

see explanation

Step-by-step explanation:

(a)

Given y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition when x = 3, y = 18 , then

18 = 3k ( divide both sides by 3 )

6 = k

y = 6x ← equation of proportion

(b)

(i)

when x = 12 , then

y = 6 × 12 = 72

(ii)

when y = 42

42 = 6x ( divide both sides by 6 )

7 = x
