Answer:

0.571428571429 grams per cm³

Step-by-step explanation:

density = mass/volume

Let’s calculate the volume V of the pyramid :

V = (1/3)×base×height

= (1÷3)×(5×7)×9

= 105 cm³

Then

The density = mass/volume

= 60÷105

= 0.571428571429

a video game arcade offers a yearly membership with reduced rates for game play. A single membership costs $60 per year. Game to

7nadin3 [17]

slope is $0.10 ($1.00 per 10 tokens = $0.10)

y-intercept is $60 ($60 is the annual fee)

y = .10x + 60 (y = mx + b)

domain is x ≥ 0 (you can't buy a negative number of token)

range is y ≥ 60 (input the domain (x ≥ 0) to find the range)

Answer: the y-intercept of the function is $60

Let P=x^2+6 PLEASE SHOW WORK!! 15 POINTS

stellarik [79]

Answer:

Step-by-step explanation:

P = x^2 + 6

$(x^2+6)^2 - 21 = 4x^2 + 24\\(x^2+6)^2 - 4x^2 - 45 = 0$

Solving for 4x^2:

P = x^2 +6

P - 6 = x^2

4(P - 6) = 4x^2

Substitution:

$p^2 - 4p - 24 - 45 = 0\\p^2 -4p - 69 = 0$
