Answer:
cos90* = 0.
Step-by-step explanation:
Look up the unit circle or type it into your calculator
I believe it is -1 since -3 times -1 equals 3 and the rate of change is based on the slope of a line
Answer:
To graph:
Step-by-step explanation:
Plot your first point at (0,3) as it's your y-interecpt.
Then from that point move 2 up and 1 over to the right for your second point. I did this since 2 is your slope.

The required values are ~

The volume of the original prism is calculated by multiplying the area of the base by the height,
volume = (8 cm²)(6 cm) = 48 cm³
By the word dilated we mean to say that the dimensions of the new prism is 5/4 times that of the original solid. If we let x be the volume of the new solid,
x / 48 cm³ = (5/4)³
The value of x from the equation above is equal to 93.75 cm³.
