Sorry if they are wrong...
You can write out the equation like so: t = 2(d) and the dvd costs d. So, d + 2d = 1296. Which is also 3D=1296. So divide 1296/3 to solve for the cost of the DVD player = 432 and the cost of the tv is 2(d) or 2 x 432 = 864.
Answer:
4.58257569 meters (Could probably get away with rounding it to 4.6 meters)
Step-by-step explanation:
Pythag theorem
a^2 +b^2 =c^2
Insert your numbers
10^2+b^2=11^2
Simplify squares
100+b^2=121
subtract 100 from both sides
b^2=21
sqrt both sides
sqrt(b^2)=sqrt(21)
simplify sqrts to get b
b= 4.58257569
Answer:
A, C, and D
Step-by-step explanation:
The rate of change will simply be the slope of the line, which we can find by taking the change in y and dividing that by the change in x:
slope = 
Thus, the slope is 3/2 = 1.5.
Since the slope remains constant throughout the graph, we know that A is correct. In addition because the points 0, 2, 4, and 6 are on the graph, the rate of change between any of the two points will still be the constant 1.5, making C and D correct as well.
So, we can choose A, C, and D.
Hope this helps!
12 i took quiz I hope this helped if i am wrong i am soooooo sorry
