(5.8 × 105)(6.4 × 102)

1 answer:

6 0

Hi well you didn’t tell me weather your adding them, subtracting, dividing, or multiplying. So here is the answer for all 4 of them. Adding them you get 1261.8, subtracting then you get -43.8, multiplying them you get 397555.2, and dividing them you get 1015/1088. If you just need the answer for each one (5.8x105) is 609 and (6.4x102) is 652.8. Hopefully I helped in some type of way. Have a good night :)

Answer:

Reflection over the y-axis and rotation of 180°

Step-by-step explanation:

We have,

Rectangle ABCD with co-ordinates A(-4,2), B(-4,1), C(-1,1) and D(-1,2).

It is transformed to a new rectangle A'B'C'D' with co-ordinates A'(-4,-2), B'(-4,-1), C'(-1,-1) and D'(-1,-2).

The graph of both the triangles is shown below.

we see that,

The rectangle ABCD is reflected about y-axis and then rotated 180° to obtain A'B'C'D'.

Reflected about y-axis Rotation of 180°

A= (-4,2) (4,2) A'= (-4,-2)

B= (-4,1) (4,1) B'= (-4,-1)

C= (-1,1) (1,1) C'= (-1,-1)

D= (-1,2) (1,2) D'= (-1,-2)

Hence, the second rectangle is formed by: Reflection over the y-axis and rotation of 180°.

Answer:

a) Since the income is more than the cost, she makes a profit.

b) To make profits, she must sell at least 17 necklaces

Step-by-step explanation:

Inequalities

The costs of selling jewelry at a fair are $135 to rent a booth and $4 for each necklace. The cost function is:

C(n) = 135 + 4n

Where n is the number of necklaces she sells at the fair. She sells each necklace at $12 each, thus the income function is:

R(n) = 12n

a) If she sells n=17 necklaces, it will cost:

C(17) = 135 + 4*17 = 203

And the income is:

R(17) = 12*17= 204

Since the income is more than the cost, she makes a profit.

b) To make a profit R(n) > C(n), thus:

12n > 135 + 4n

Subtracting 4n:

8n > 135

n > 135/8

n > 16.875

Thus, to make profits, she must sell at least 17 necklaces

Answer:

$\displaystyle \frac{\pi}{6}$

Explanation:

According to the unit circle, $\displaystyle \frac{\pi}{3}$ and $\displaystyle \frac{\pi}{6}$ are the radian measures you are looking for because all y-coordinates are associated with the sine function, so when evaluating, you will arrive at this:
