Answer:
The correct option is (A).
Step-by-step explanation:
The function representing the growth of number, in billions, of the DNA sequences in a database x years since 2010 is:
The general growth function can be represented as:
Here,
<em>y</em> = final value
<em>a</em> = initial value
<em>r</em> = growth rate
<em>t</em> = time
Com-paring the two functions we get:
This implies that the annual increase rate in number, in billions, of the DNA sequences is 32%.
Thus, the correct option is (A).
Let's say the prisms dimensions were 2×2×2 and you doubled the height 4×2×2.
2×2×2=8 while 4×2×2=16
another example:
4×3×6=144 while 8×3×6=288
therefor it doubles the volume of the prism
Answer:
The given coordinates of the vertices of rectangle ABCD are A(−2,2),B(4,2),C(4,−2).
We are to plot D on the graph.
Since ABCD is a rectangle, the abscissa of D will be that of A and the ordinate of D will be that of C.
Step-by-step explanation:
Answer:
1/13
Step-by-step explanation:
There are 4 nines in a deck so the probability is 4/52 = 1/13
I first found x using the second equation :
-2x+4y=15
-2x = -4y+15
x =2y-7.5
Then, I substituted this value into the OTHER equation :
2x+5y=7
2(2y-7.5)+5y=7
4y-15+5y=7
9y=22
y=2.444
So you have you y value. Now, input this value into any one of the other equations (it doesn't matter which) to find x.
-2x+4y=15
-2x+4(2.444)=15
-2x+9.776=15
-2x=5.224
x=-2.612.
So the solution for this system of functions is (-2.612, 2.444).
