The coordinates of point B are (-1,-5)

Step-by-step explanation:

The formula for mid-point is given by:

M = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})

Given

M(x,y) = (-3,-3)

A(x1,y1) = (-5, -1)

We have to find the coordinates of B(x2,y2)

So,

M(x,y)= (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\(-3,-3) = (\frac{-5+x_2}{2} , \frac{-1+y_2}{2})\\putting\ respective\ coordinates\ equal\\-3 = \frac{-5+x_2}{2}\\-3 * 2 = -5+x_2\\-6 = -5+x_2\\-6+5 = x_2\\x_2 = -1\\And\\-3 = \frac{-1+y_2}{2}\\-3*2 = -1+y_2\\-6 = -1+y_2\\-6+1 = y_2\\y_2 = -5

Hence,

The coordinates of point B are (-1,-5)

Takumi started studying how the number of branches on his tree changes over time.
Musya8 [376]

Answer:

Grows, Factor of 2

Step-by-step explanation:

The relationship between the elapsed time, t, in years, since Takumi started studying his tree, and the total  number of its branches, N(t), is modeled by the function:

N(t) = 63. 2^t

For illustration, let us take the growth for the first three years after he started studying the number of branches.

When \:t=1, N(1) = 63. 2^1=126\\When \:t=2, N(2) = 63. 2^2=252\\When \:t=3, N(3) = 63. 2^3=504\\504\div 252=252\div 126=2

We notice that for each subsequent year, the number of branches doubles.

Therefore:

Every year, the number of branches  <u>grows</u> by a factor of <u>2.</u>

Please answer this question <br>It's really important ​
Bumek [7]

for #3:

a) 0.9

b) 0.4

c) 0.7

d) 0.08

e) 3.9

f) 1.6

g) 5.5

h) 12.4

And for #4:

The answer is $131.63

Nathan earns 9.75 dollars in <u>one</u> hour, and you want to figure out how many he makes in <u>thirteen and a half</u> hours. To do this, just multiply 9.75 by 13.5.

9.75*13.5 is 131.625. However, money only goes to the hundredths place, which means there are only 2 decimal places. This means you should <u>round 131.625 to the hundredths place</u>, which makes 131.63.

If anyone could help out with this one i would really appreciate it <br><br> f(2)=?
algol13

Answer:

f(2) = 0

Step-by-step explanation:

Function f(t) is defined in three different ways depending on the value of t.

For t = 8, function f(t) is -64/t.

For t = 10, function f(t) is 14 - t.

We are not asked about f(8) or f(10). We are asked about f(2). The third definition of function f(t) is for all values of t that are not 8 or 10. 2 is not 8 or 10, so use the third definition of function f(t) and plug in 2 for t.

f(t) = t^2 - 3t + 2 for t not equal to 8 or 10.

f(2) = 2^2 - 3(2) + 2

f(2) = 4 - 6 + 2

f(2) = 0

Gina paints beach scenes on notecards. She sells packages of 8 notecards for $8 for one package, $16 for 2 packages, and $24 for
Hitman42 [59]
In this question, each package has 8 notecards. 
one notecard costs $8
2 notecards cost $16
3 notecards cost $24
if n - number of packages
d - selling price in dollars
We can see that with each additional notecard bought the cost increases by $8
therefore there's a proportional relationship between n and d
As n increases, d increases by the same amount.
if we put it in an equation,
d = 8*n
n - 1 package and d is 8 
if n - 2
d = 8*2
d = 16
Therefore we can use the following equation;
d=8n
