Answer:
x <7
Step-by-step explanation:
3x – 4 < 17
Add 4 to each side
3x – 4+4 < 17+4
3x < 21
Divide each side by 3
3x/3 < 21/3
x <7
Answer:
$50 is the value of interest earned in the first installment on a single bond
Step-by-step explanation:
Applying Interest earned in the first installment on a single bond ;
= PRT/100
P = $1.000
R = 5%
T = 1
Plugging the values in the equation ;
Interest = 1000 x 5 x 1 /100
= $50, hence option A is the correct one.
Answer:
48 mm ^ 2
Step-by-step explanation:
We know we have a cube of side x, therefore the volume of that cube will be equal to:
V = x ^ 3, because it is a cube and each side is the same.
Now the derivative of the volume with respect to the length (that is, x) would be:
dV / dx = 3 * (x ^ 2)
They tell us that x takes a value of 4, replacing we have:
dV / dx = 3 * (4 ^ 2) = 48
That is, 48 mm ^ 2 would be the value of dV / dx when x is equal to 4 mm.
