Answer:Plug the numbers into the exponential growth formula:

Now work backwards to get the answer:

1)Divide 120150 by 60100 to get 1.998668885

2) Find the 11th root of ANS:

3) Minus 1 from your answer to give 0.064976629

4)Multiply your answer by 100 to give you the rate of x%, which is 6.5 to 1d.p

x=6.5 (1 d.p.)

Btw, this answer also works if you plug it back into the equati

Find the center of the circle that you can circumscribe about DABC.

Vlada [557]

The center of the circle that circumscribe about DABC is $(h,k) = (1, 5)$ .

A circle can be modelled after a expression of the form:

$A\cdot x + B\cdot y + C =-x^{2}-y^{2}$ (1)

We can determine all coefficients by knowing three <em>distinct</em> points on plane.

If we know that $(x_{1}, y_{1}) = (2, 8)$ , $(x_{2}, y_{2}) = (0, 8)$ and $(x_{3}, y_{3}) = (2, 2)$ , then the solution of the system of linear equations is:

$2\cdot A + 8\cdot B + C = -68$ (2)

$8\cdot B + C = -64$ (3)

$2\cdot A + 2\cdot B + C = -8$ (4)

$A = -2, B = -10, C = 16$

Now we proceed to <em>complete</em> squares and factor each resulting perfect square trinomial in order to determine the coordinates of the center of the circle:

$x^{2}+y^{2}-2\cdot x -10\cdot y +16 = 0$

$(x^{2}-2\cdot x +1)-1+(y^{2}-10\cdot y +25)-25 +16 = 0$

$(x-1)^{2}+(y-5)^{2}= 10$

The center of the circle that circumscribe about DABC is $(h,k) = (1, 5)$ .

I Need The Answer Plz!!! Geometry Is Hard!!!

Scorpion4ik [409]

Answer:

B. 10

Step-by-step explanation:

First, we need to recognize that the two triangles are similar (the triangle with a leg value of 21 and the triangle with a leg value of 4 and hypotenuse x)

Let's first label the leg of the second triangle as y.

Then, we can set up this equation

$\frac{21}{y} =\frac{y}{4}$

Cross multiplying gives us

84=y^2

So, y=sqrt(84) or 2 sqrt(21).

Now, using the pythagorean theorem, we get

4^2+2sqrt(21)^2=x^2

100=x^2

x=10

Math someone help me

liubo4ka [24]

Answer:

One bottle of soap will hold 3/8

Step-by-step explanation:

3/4= The amount of soap she has in total

3/4= 6/8 which is the same amount but now we can divide it by 2

.75 (6/8) divided by 2= .375 (3/8)

So each soap dispenser will have 3.75 liters of soap.

Sentences: To check our work

.375x2= .75

3/4 divided by 2= 3.75

Answer:

a or 116

Step-by-step explanation:

First you solve the blue part which is 14*14=196. Then solve the green part 10*8=80. Subtract blue minus green. Which gives you 116.

Kruka [31]

Answer:

24!

Step-by-step explanation:

I will refer the people to A,B,C, and D

24 is the answer.

4 choices for the first position.

3 choices for the second.

2 choices for the third.

1 for the fourth.

4*3*2*1=24

Here it is listed out where a,b,c,d are the 4 people:

abcd

abdc

acbd

acdb

adbc

adcb

bacd

badc

bcad

bcda

bdac

bdca

cabd

cadb

cbad

cbda

cdab

cdba

dabc

dacb

dbac

dbca

dcab

dcba

(of course, this assumes that there is a direction to the line, or a 'front' and a 'back'. If direction doesn't matter then the answer is 12, since every combination above has a reverse. e.g., abcd and dcba. The list becomes:

abcd

abdc

acbd

acdb

adbc

adcb

bacd

badc

bcad

bdac

cabd

cbad
