Answer:

False (under assumption T(2,-3) means move it right 2 units and down 3 units).

Step-by-step explanation:

The statement is false.

T(2,-3) means move the point right 2 (so plus 2 on the x-coordinate) and down 3 units (so minus 3 on the y-coordinate).

So (1,6) will become (1+2,6-3)=(3,3) after the translation.

The point (1,12) will become (1+2,12-3)=(3,9).

If the statement were "Under the translation T(2,-3) the point (1,12) will become (3,9)", then it would be true.

Or!

If the statement were "Under the translation T(2,3) the point (1,6) will become (3,9)", then it would be true.

Answer:

(For the first two questions I do believe that you will need a protractor to calculate the angles.)

15) $-(\frac{7\pi }{18} )\\$ measures out to -70° in order to display that the angle would be in quadrant IV (the bottom right quadrant.)

The first image attached shows where the angle should be located.

16) $\frac{\pi }{3}$ is equal to 60° (the line you draw will be in quadrant 1 (the top right quadrant))

17) 350° is $\frac{35\pi }{18}$ or 6.11 (the answer depends on the format the professor wants.)

18) 240° is $-(\frac{4\pi }{3})$ radians or -4.19 (I am rounding to the nearest hundredths place the unsimplified answer is −4.18879020...)

A population of 100 frogs increases at an annual rate of 22%. How many frogs will there be in 5 years? Write an expression to re

gizmo_the_mogwai [7]

Exponential growth of the form:

F=Ar^t

F=100(1.22)^t

F(5)=100(1.22)^5

F(5)=270.27

F(5)=270 to the nearest frog...

....

1.22=r^12

r=1.22^(1/12)

F=100(1.22^(1/12)^t)

F=100(1.22^(t/12)) now it will produce monthly populations...

Say we did the same as before but instead of 5 years you have 60 months...

F(60)=100(1.22^(60/12))

F(60)=270 to the nearest frog... :P

ms. James has a 6 square foot bulletin board and a 12 square food bulletin board. She wants to cover both boards with index card

Anon25 [30]

Answer:

She need 72 index cards.

Step-by-step explanation:

Ms. James has a 6 square foot bulletin board and a 12 square food bulletin board and she wants to cover both boards with index cards without gaps or overlaps.

Each index card has an area of $\dfrac{1}{4}$ square foot.

Dividing the area of each board with the area of the index card will yield the the number of cards she needs to cover up completely.

Let us assume T₁ and T₂ are the number of cards she needs to cover 6 square feet food bulletin board and 12 square feet food bulletin board respectively. So

$T_1=\dfrac{6}{\frac{1}{4}}=24,\\\\T_2=\dfrac{12}{\frac{1}{4}}=48$

Therefore, in total she need 24+48=72 index cards.

Beyonce and Guns N Roses had the two top-grossing North American concert tours for 2016, together generating $300 million in tic

ipn [44]

Answer:

Step-by-step explanation:

B + G = 300 (million)

G = B - 38 (million)

B + B - 38 = 300

2B - 38 = 300

2B = 300 + 38

2B = 338

B = 338/2

B = 169 million <=== Beyonce

G = B - 38

G = 169 - 38

G = 131 million <==== Guns N Roses
