We take the equation <span>d = -16t^2+12t</span> and subtract d from both sides to get
0<span> = -16t^2+12t - d
We apply the quadratic formula to solve for t. With a = -16, b = 12, c = -d, we have
t = [ -(12) </span><span>± √( 12^2 - 4(-16)(-d) ) ] / [2 * -16]</span>
= [- 12 ± √(144-64d) ] / (-32)
= [- 12 ± √16(9-4d)] / (-32)
= [- 12 ± 4√(9-4d)] / (-32)
= 3/8 ±√(9-4d) / 8
The answer to your question is t = 3/8 ±√(9-4d) / 8
This is super simple. Begin with cross multiplying
35/x=7/13 becomes (35)*(13)=(7) *(x)
Then multiply my love muffin, you get...
455=7x
divide both sides by 7
65=x
-or-
x=65
hope that helped :)
The rate of change of the given equation is: 0.86
Step-by-step explanation:
Rate of change or slope is the steepness of a linear function or line.
When an equation is given in the form of slope-intercept form, the co-efficient of x is the slope or rate of change of the equation.
Given equation is:
We can see that the co-efficient of x is 0.86
Hence,
The rate of change of the given equation is: 0.86

it would be 48 because you would multiply 8 and 12 but then divide by 2
Answer:
12.5% Step 1 to find volume of Pyramid A Step 2 is find percentage through division then multiplication of 100
Step-by-step explanation: Length of one side of the base (a) = 14 in
Height of square pyramid (h) = 6 in
Using the square pyramid volume formula,
Volume = 1/3 x a^2 x h
Volume = 1/3 x 14^2 x 6
Volume = 392 in3
The volume Pyramid A is 392 cubic inches.
Pyramid A has a volume = 392 cubic units Pyramid B has a volume of 3,136 cubic inches. to find percentage 392 of 3136 we divide then * 100 To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator... = (392/3136 ) x 100% = 12.5% Proof is (12.5 * 3136 ) / 100 = 392
