can someone help me and you need to round to nearest whole number

Answer:

A and C

Step-by-step explanation:

Statements B) BA ≅ BC and C) AE ≅ DE guarantee that ray BE bisects angle ABC.

Statement B states that BA is congruent to BC. This means that side AB is the same length as side BC. Since the bisector of an angle divides the opposite side into two segments with equal lengths, this guarantees that ray BE bisects angle ABC.

Statement C states that AE is congruent to DE. This means that the segments AE and DE have the same length. Since the bisector of an angle divides the opposite side into two segments with equal lengths, this guarantees that ray BE bisects angle ABC.

The other statements are not sufficient to guarantee that ray BE bisects angle ABC. For example, if BA is congruent to BD, this does not mean that the segments AE and DE have the same length. Similarly, if BD is congruent to DE, this does not mean that side AB is the same length as side BC.

Therefore, the correct answers are B and C.

The answer is 1/81 cm squared

Step-by-step explanation:

Step-by-step explanation:

Answer:

Part A

The vertex of the graph lies at (40,18). This is the maximum value on the graph. This means the balloon reached a maximum altitude of 1,800 meters about 40 minutes after its launch.

Part B

One of the x-intercepts of the function lies somewhere between x = 82 and x = 83. This is this point where the balloon is at zero altitude, or sea level. So, the balloon stays in the air for a little over 82 minutes. There is another x-intercept to the left of the origin. But a negative time value doesn’t make sense. So, we won’t considerate it for this scenario.

Part C

The -y-intercept of the function lies at (0,2). This is the starting point of the balloon’s journey. The point the balloon launched from was 200 meters above sea level.

Part D

We can’t interpret negative time values in this situation. So, the domain of the function is restricted to positive values of x. A negative y-value indicates an altitude below sea level. While some locations have negative altitudes, we can consider only positive values for this scenario. So, we should only consider positive values of y. So the domain of the function is restricted to only those values of x that produce positive values of y. Since we can’t see the x-intercept clearly from the graph, we’ll consider the domain of the function to be [0, 82].

Part E

Average rate of change on [0, 20] = f(20)-f(0) / 20-0

= 14-2 / 20

= 12 / 20

=0.6

Average rate of change on [60, 80] = f(80)-f(60) / 80-60

= 2-14 / 20

= -12 / 20

= -0.6

In this case, the rate of change represents the change in the balloon’s altitude within a time interval. The average rate of change on [0, 20] is positive. This indicates that the balloon is ascending, or climbing, during the first 20 minutes of its journey.

The average rate of change on [60, 80] is negative. This indicates that the balloon is descending between 60 and 80 minutes. Although negative, the rate of change in the second interval has the same absolute value as the rate of change for the first interval. So, during the last 20 minutes the balloon is descending at the same rate it was ascending during the first 20 minutes.

Answer:

A: Negative

B: 1) Decreases

   2) Increases toward 100

C: The point (1,55) and (5,97) are outliers.

Step-by-step explanation:

Because the grade decreases as the number of abscenses increases, it is called a negative association.

Outliers are the point that stick far out from the rest of the points.  Both (1,55) and (5,97) are far away from the rest of the points.  And don't follow the general trend of the graph.

Luca gave them 6 treats.

His father gave them t (unknown) treats.

All together, they got 10 treats.

This would be the equation:

[tex]6+t=10[/tex]

To solve, subtract 6 from each side.

[tex]6-6+t=10-6\\t=4[/tex]

Therefore, Luca's father gave the dogs 4 treats.

Answer:

31.7 min

Step-by-step explanation:

Given that;

N(t) = Noe^kt

No = amount of radioactive isotope initially present

N(t) = amount of radioactive isotope present at time t

t = time taken

k = decay constant

5.25 = 14e^-k16

5.25/14 = e^-k16

0.375 = e^=k16

ln(0.375) = =-16k

k = ln(0.375)/-16

k = 0.0613 min^-1

So time taken for 2 mg to remain;

2 = 14e^-0.0613t

2/14 = e^-0.0613t

0.1429 = e^-0.0613t

ln(0.1429) = -0.0613t

t = ln(0.1429)/-0.0613

t = 31.7 min

Answer:

=z ^(-11) + ^(-15)

= z ^ -26

Answer:

z^-11 times z^-15 = z^-26

Step-by-step explanation:

According to exponential properties, multiplying two numbers that have exponents with the same bases should be added.

Negative exponents mean to go from a^-x to 1/a^x.

Using these properties, we evaluate the expression.

Both terms have the same base, z, so we can go ahead and add the exponents.

-11 + -15 = -26

z^-11 * z^-15 = z^-26

Because the instructions specifically say to leave it in z^n form, our answer is z^-26.

Answer:

Median- 12

Q1- 5

Q3- 43

IQR- 38

Step-by-step explanation:

2, 5, 11, 13, 43, 45

Put your numbers in order of least to greatest

Since there is no given median as the amount of numbers is even, find the number in between the 2 middle numbers, in this case, the number would be 12, as it is in between 11 and 13.

To find Q1 and Q3, you need to find the first and third median, which would be 5 and 43. To find the IQR, you need to subtract Q3 from Q1, which would give you 38 in this equation

Answer:

The Correct option is 36.60

Step-by-step explanation:

The key to solving this question lies around measurement conversion,specifically converting grams into its equivalence in kilograms.

1000 grams equal one kilogram

9 grams=9/1000 kg

9 grams=0.009 kg

70 grams=70/1000 kg

70 grams=0.07 kg

Julie pays=$600*0.009=$5.4

Jacques pays=$600*0.07=$42

Jacques pays   $36.60 more ($42-$5.4) than Julie paid

Option is wrong because that was what Julie paid

Option D is wrong because that was what Jacques paid

Option B is obviously wrong

Answer:

25² · 40 π in.³

Step-by-step explanation:

V = πr²h

π · 25² · 40

≈ 78539.81634

Since your question wants it in a different way, you have to know the formula.

V = πr²h

V = r² · h π in³

Answer:

Step-by-step explanation:

distance between ( 3 , 9 ) and ( 3 , - 3 ) = 9 - (-3) = 12 because x is the same for both pts

12 is the diameter of circle so its radius = 12/2 = 6

center is in the middle: ( 3 , (9-3)/2 ) = ( 3, 3 )

so the circle's eqn is

( x - 3 )^2 + ( y - 3 )^2 = 6^2

Answer:

Yes, they would get different values

Step-by-step explanation:

Given

[tex](4 * 35) + (36 * 8)[/tex]

Required

Would there be different value for the expression?

From the question, we understand that both students made no computational errors. This doesn't mean that the students cannot make other errors.

For instance, the expression can be solved (wrongly) in the following ways;

[tex](4 * 35) + (36 * 8) \to 4 * 35 + 36 * 8 \to 140 + 36 * 8 \to 176 * 8 = 1408[/tex]

[tex](4 * 35) + (36 * 8) \to 4 * 35 + 36 * 8 \to 4 * 71 * 8 \to = 2272[/tex]

While the correct solution is:

[tex](4 * 35) + (36 * 8) \to 140 + 288 =428[/tex]

Hence, it is possible for two students to get different values
