Answer:

Step-by-step explanation:

23.m∠2=x+60

as the sides are equal.

so angles are also equal.

m∠2=45

x+60=45

x=45-60=-15°

so C

24.

74+74+m∠2=180

m∠2=180-148=32°

so 3x-4=32

3x=32+4=36

x=12°

C

25.

as the three sides are equal so angle are equal.

m∠2=60

7x-10=60

7x=60+10=70

x=10

D

A moose population is growing exponentially following the pattern in the table shown below. Assuming that the pattern continues,
EleoNora [17]

Answer:

  •   <u> 7,692 moose.</u>

Explanation:

The table that shows the pattern for this question is:

Time (year) Population

  0                   40

  1                     62

  2                    96

  3                   149

  4                   231

A growing exponentially pattern may be modeled by a function of the form P(x) = P₀(r)ˣ.

Where P₀ represents the initial population (year = 0), r represents the multiplicative growing rate, and P(x0 represents the population at the year x.

Thus you must find both P₀ and r.

<u>1) P₀ </u>

  Using the first term of the sequence (0, 40) you get:

   P(0) = 40 = P₀ (r)⁰ = P₀ (1) = P₀

Then, P₀ = 40

<u>  2) r</u>

Take two consecutive terms of the sequence:

  • P(0) = 40 r⁰ = 40
  • P(1) = 40 r¹ = 40r = 62
  • P(1) / P(0) = 40r / 40 = 62/40
  • r = 62/40 = 1.55

 

You can verify that, for any other two consecutive terms you get the same result: 96/62 ≈ 149/96 ≈ 231/149 ≈ 1.55

<u>3) Model</u>

 

Thus, your model is P(x) = 40(1.55)ˣ

<u> 4) Population of moose after 12 years</u>

  • P(12) = 40 (1.55)¹² ≈ 7,692.019 ≈ 7,692, which is round to the nearest whole number.

Is 7x=5x-25+30 no solution,one solution, or all real numbers? <br><br> Thank you!
viva [34]

One solution let's find that

\\ \rm\hookrightarrow 7x=5x-25+30

\\ \rm\hookrightarrow 7x=5x+5

\\ \rm\hookrightarrow 2x=5

\\ \rm\hookrightarrow x=5/2

A line with a negative slope intersects a horizontal line 3 units above the x-axis. Select each point that can not be the inters
AnnyKZ [126]

Step-by-step explanation:

Since both lines intersect each other 3 units above the x-axis, the y-value of the point of intersection must be 3.

Looking at the options, (-3, 5), (3, -2) and (0, -3) are all invalid points.
