Then we know that we originally had 38 grams of the substance, the rate of growth is 18%, and that the time it was allowed to grow is 6 days. Then we have using the exponential growth model that the amount of the sample after 6 days will be S = P e^rt where P is the initial sample amount, r is the rate of growth, t is the time, and S is the final sample amount. S = 38 e^ .18*6 = 38 e ^ 1.08 = 111.8978 Thus if there were 38 grams of the substance present at the beginning of the study the mass of the sample would be 111.8978 grams after the study.

Answer:

right angle and acute

Step-by-step explanation:

because one angle is 90° and also two sides of the triangle are equal

The given triangle is Right angled triangle and Isosceles triangle.

Triangle is a two dimensional shape having three side and sum of all angles is equals to [tex]360^0[/tex].

We have,

A triangle with an angle of [tex]90^0[/tex] and two equal sides.

So,

We know that,

When a triangle have any angle equals to [tex]90^0[/tex] then it is  Right angled triangle.

Now,

When a triangle have any two sides equal then it is Isosceles triangle.

So,

From the above mentioned statements we can say that triangle is Right angled and Isosceles triangle.

Hence, we can say that the given triangle is Right angled triangle, Isosceles triangle.

so the mean is average

you add all then divide by how many (i think)

sooo

(13.4 + 16.2 + 15 + 16.5 + 12.5) / 5

So you simply add the numbers given and then divide them of the amount of numbers they're to get your answer.

====================================================

Explanation:

Focus on triangles SVT and UVT.

They are congruent triangles due to the fact that SV = VU and VT = VT. From there we can use the LL (leg leg) theorem for right triangles to prove them congruent.

Since the triangles are the same, just mirrored, this means ST = UT = 23.

-----------------------

Following similar reasoning as the previous section, we can prove triangle RVU = triangle RVS.

Therefore, RS = RU = 8

-----------------------

SV = VU = 5 because RT bisects SU.

Bisect means to cut in half. The two smaller pieces are equal.

-----------------------

SU = SV + VU = 5+5 = 10

Refer to the segment addition postulate.

Answer:

ST=23

RU=8

SV=5

SU=10

Step-by-step explanation:

RT bisects the whole quadrilateral, so a line on one side will be the same length as the line on the opposite side of RT. So:

1. ST=UT, UT=23, so ST=23

2. RU=RS, RS=8, so RU=8

3. SV=VU, VU=5, so SV=5

4. SU=2*SV, 5*2=10, so SU=10

If you still have no clue, just imagine the points R, S, T, and the lines connecting them (this will make a triangle). Then reflect the triangle across line RT, and name the new S point U (the new triangle still has the same line measures) . Make a line from S to U and make a point V from where RT and SU meet. This will make the figure in the picture.

Have a nice day! :)

Answer:

56.25 pi  cm^2

Step-by-step explanation:

To find the area of the circle,

we use the formula

A = pi r^2, where r is the radius

We know the diameter is 15 so we can find the  radius from

r = d/2  where d is the diameter

r = 15/2

A = pi ( 15/2) ^2

A = pi ( 225/4)

A = 56.25 pi  cm^2

Answer:

2nd option

› 56.25π cm²

Step-by-step explanation:

we know ,

area of circle is πr²

so,

given,

diameter,d = 15cm

radius,r = d/2 = 15/2 = 7.5 cm

so,

area = πr²

= (7.5×7.5)π

= 56.25π cm²

Answer:

x = -7

y = 1

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable x

[2] 7x = 3y - 52

[2] x = 3y/7 - 52/7

// Plug this in for variable x in equation [1]

[1] 4•(3y/7-52/7) + 3y = -25

[1] 33y/7 = 33/7

[1] 33y = 33

// Solve equation [1] for the variable y

[1] 33y = 33

[1] y = 1

// By now we know this much :

x = 3y/7-52/7

y = 1

// Use the y value to solve for x

x = (3/7)(1)-52/7 = -7

Solution :

{x,y} = {-7,1}

Answer:

Y=2

Step-by-step explanation:

On the Y axis you go up two and yeah that's about it

Answer:

y = 5/4x - 6

Step-by-step explanation:

First, put 4x + 5y= -45​ in y = mx + b form

4x + 5y= -45​

5y = -4x - 45

y = -4/5x - 9

So, the slope is -4/5. Perpendicular lines have a opposite reciprocal slope, so the line's slope will be 5/4 right so to find the equation of the perpendicular line in this question, plug in the slope and given point into y = mx + b, and solve for b

y = mx + b

-11 = 5/4(-4) + b

-11 = -5 + b

-6 = b

so you should Plug in b and the slope into y = mx + b

y = 5/4x - 6

So, the equation is y = 5/4x - 6

Step-by-step explanation:

1.they should divide each person into 3 teams

Answer: 280

Step-by-step explanation: So you have 9 people. One out of those 9 people could go in any of the spots for participants. You could start off with 9*8*7 because you want to work your way down and it doesn't matter which order but just the number of people in each group. 9*8*7 is one group, 6*5*4 is the second group and 3*2*1 is the third group. Now, you want to take each of those equations and divide them by 3!. You do this because there are 3 teams and 9 people are being distributed between them.

9*8*7                        6*5*4                            3*2*1

--------     = 84         -----------     =20 and      -----------  =1

 3!                              3!                                   3!

Now that you have 84, 20 and 1, you multiply them and once again divide the product by 3! or cancel. You will get 14*20*1 =280

Hope it helps!
