Mathematics
1 answer:
azamat3 years ago
5 0

Answer:

The answer is D.

Step-by-step explanation:

Well, all the equations are the same except for the symbol so you don't need to figure out the equation of the line.

Anyways, note that the line is dotted, which means it cannot be A nor B since they have an "equal to."

Also, note that the shaded region is above the graph. Since it is above, it means that y is greater than whatever x is.

Thus, the answer is D.

a stack of cards is placed next to a ruler, and the height of stack measured to be 3/4inches. how thick is one card
4vir4ik [10]

Total thickness of the stack of cards = 3/4 inch or 0.75 inch

In a full stack of cards, there are 52 cards.

Hence, the thickness of 52 cards = 0.75 inch.

To find the thickness of one card, we divide the total thickness with the total number of cards.

Thickness of one card = \frac{0.75}{52} = 0.014423 inch

1 inch = 2.54 cm

0.014423 inch is approximately equal to 0.34 cm.

Answer = 0.34 cm

Solve the quadratic. x^2+8x+3=0
Reil [10]
Factor
find wht 2 numbers add to 8 and multiply to 3
none do

use quadratic formula which can be used when
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^{2}}-4ac }{2a}

a=1
b=8
c=3

x=\frac{-8+/- \sqrt{8^{2}-4(1)(3)} }{2(1)}
x=\frac{ -8+/- \sqrt{64-12} }{2}
x=\frac{ -8+/- \sqrt{52} }{2}
x=\frac{ -8+/- 2 \sqrt{13} }{2}
x=-4+/- \sqrt{13}

x=-4+ \sqrt{13} or x=-4- \sqrt{13}
aprox x=-7.60555 or x=-0.394449
