4) The population of the city in the year 2000 was 50000. The population is decreases by 0.95 each year

Step-by-step explanation:

a) Given an equation:

ax² + bx + c = 0

The equation would have imaginary solutions if b² - 4ac is negative. That is:

b² - 4ac < 0

Given an equation: 3x²+2kx+2=0

a) If k = -5

a= 3, b = 2k = 2 × -5 = -10, c= 2

b² - 4ac = (-10)² - 4(3)(2) = 76 > 0

It would not produce imaginary solutions

b) If k = -3

a= 3, b = 2k = 2 × -3 = -6, c= 2

b² - 4ac = (-6)² - 4(3)(2) = 12 > 0

It would not produce imaginary solutions

c) If k = -1

a= 3, b = 2k = 2 × -1 = -2, c= 2

b² - 4ac = (-1)² - 4(3)(2) = -23 < 0

It would produce imaginary solutions

d) If k = 2

a= 3, b = 2k = 2 × 2 = 4, c= 2

b² - 4ac = (4)² - 4(3)(2) = -8 <0

It would  produce imaginary solutions

e) If k = 3

a= 3, b = 2k = 2 × 3 = 6, c= 2

b² - 4ac = (6)² - 4(3)(2) = 12 > 0

It would not produce imaginary solutions

f) If k = -5

a= 3, b = 2k = 2 × 4 = 8, c= 2

b² - 4ac = (8)² - 4(3)(2) = 40 > 0

It would not produce imaginary solutions

2)

A. Distribute 4 to the quantity ( x+1). to get:

1/2 x+12=8+4x+4

B. Add − 8 to each side of the equation. to get:

1/2 x+4=4( x+1)

C. Distribute 12 to the quantity ( x+1). This is not correct

D. Multiply each side of the equation by 2. to get:

x + 24 = 16 + 8(x +1)

F. Add together the 8 and the 4 on the right side of the equation. This is not correct

G. Multiply the left side of the equation by 2 to eliminate the fraction. This is not correct

3)

[tex]f(x)=x^2-2(r-s)x+(r-s)^2+(r+s)\\f(x)=x^2-2rx+2sx+r^2+s^2-2rs+r+s\\f(x)=x^2+r^2+s^2-2rs-2rx+2sx+r+s=(r-x-s)^2+(r+s)\\f(x)=(r-x-s)^2+(r+s)[/tex]

4) P( x )=50,000 ( 0.95 )^x, where x represents the number of years after the year 2000

At the year 2000, x = 0 therefore

[tex]P(x)=50000(0.95)^x=50000(0.95)^0=50000[/tex]

Since 0.95 is less than 1, it represent a population decay. 0.95 is the common ratio

The population is decreases by 0.95 each year

Answer:

x=3

Step-by-step explanation:

3^x = 27

Good luck on your assignment....

Answer:

7000 mg = 7 g

18500 g = 18.5 kg

22 g = 22000 mg

4.7 kg = 4700 g

8.3 kg = 8300 g

135000 mg = 135 g

Step-by-step explanation:

First we need to use some important conversion rates so I will write them for below

1 Milligram (mg) = 0.001 Grams (g)

1 Gram (g) = 0.001 Kilogram (Kg)

1 Gram (g) = 1000 Milligrams (mg)

1 Kilogram (Kg) = 1000 Grams (g)

Using the above conversion rates we can solve these questions

Question 1

7000 mg = ? g

Using the information at the top 1 Milligram (mg) = 0.001 Grams (g) so,

0.001 × 7000 = 7 grams

Question 2

18500 g = ? kg

Using the information at the top 1 Gram (g) = 0.001 Kilogram (Kg) so,

18500 ÷ 1000 = 18.5 kg

Question 3

22 g = ? mg

Using the information at the top 1 Gram (g) = 1000 Milligrams (mg) so,

22 × 1000 = 22000 mg

Question 4

4.7 kg = ? g

Using the information at the top 1 Kilogram (Kg) = 1000 Grams (g) so,

4.7 × 1000 = 4700 g

Question 5

8.3 kg = ? g

Using the information at the top 1 Kilogram (Kg) = 1000 Grams (g) so,

8.3 × 1000 = 8300 g

Question 6

135000 mg = ? g

Using the information at the top 1 Milligram (mg) = 0.001 Grams (g) so,

0.001 × 135000 = 135 grams

Answer:

Option (2).

Step-by-step explanation:

From the figure attached,

Since there is a common difference in each successive term and previous term of y,

[tex]y_{2}-y_{1}=-9-(-6)[/tex]

           = -3

[tex]y_{3}-y_{2}=-12-(-9)[/tex]

           = -3

Therefore, this data represents a linear equation.

Now we choose two points from the table given.

Let the points are (0, -6) and (1, -9)

Slope of this line 'm' = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

m = [tex]\frac{-9+6}{1-0}[/tex] = -3

Y-intercept 'b' = -6

Equation of the line will be,

y = -3x - 6

Option (2) will be the answer.

Answer:

10*5 = 7x

Step-by-step explanation:

We can solve using cross products

10*5 = 7x

50 = 7x

divide each side by 7

50/7 =7x/7

50/7 =x

Answer:

Correct option: first one

Step-by-step explanation:

If we reflect the triangle RST over the x-axis, the y-coordinate of each point will have the sign switched, so the point S would be in (1, -5), the point R would be in (1, -1) and the point T would be in (4, -1)

Then, if we translate the resulting points 2 units to the left, we would have:

S = (-1, -5) -> matches point C

R = (-1, -1) -> matches point A

T = (2, -1) -> matches point B

So the triangles are congruent, and we can map from triangle RST to triangle ACB with a reflection over the x-axis and a translation of 2 units to the left.

Correct option: first one

Answer:

B

Step-by-step explanation:

Answer:

y[tex]\leq[/tex][tex]\frac{1}{3}[/tex]x-4; B

Step-by-step explanation:

The blue is in the y-values where it is more directed towards the negative y- values.

y=mx+b

[tex]\frac{1}{3}[/tex] slope= because rise is 1 and 3 runs and to find slope it is [tex]\frac{rise}{run}[/tex]

-4 is the "b" in y=mx+b where b represents the y-intercept and looking at the graph, the line intercepts at -4  

Answer:

This would be graph A

Step-by-step explanation:

The graph decreases means the line goes down. crosses at -7 means the y intercept is -7 and then remains constant means a horizontal line

This would be graph A

Answer:

Graph A ; Option B

Step-by-step explanation:

Consider the criteria for the graph;

[tex]Criteria;\\\\Crosses Y - axis at Point - ( 0, - 7 ),\\Decreases Before Crossing Y - axis,\\Remains Constant after Crossing Y - axis,\\[/tex]

Now take a look at each option before us;

[tex]Graph A - \\1. Travels Down,\\2. Crosses Y - axis at Point ( 0, - 7 )\\3. Remains Constant\\\\Graph B - \\1. Travels Upward,\\2. Crosses Y - axis at Point ( 0, 7 )\\3. Remains Constant\\\\Graph C - \\1. Travels Down,\\2. Crosses Y - axis at Point ( 0, - 7 )\\3. Travels Upward[/tex]

Comparing the three, we conclude that Graph A meets the provided criteria, which confirms that it is the right answer;

Step-by-step explanation:

comment if u want an explanation cus i cba to write one for no reason

Hi!

So the first thing to do is to combine the common terms on each side.

On the left side, 13 and 2a cannot be put together because 2 has a multiplier that 13 does not.

On the right side, however, there are two numbers with the multiplier a. Add those together!

3a + 2a = 5a.

13 + 2a = 5a - 14

Now we want to isolate a to one side. Let's do the right side.

To do this, we have to subract 2a from both sides to get a on only one side.

13 + 2a - 2a = 5a - 2a - 14.

Subract.

13 = 3a - 14.

We have to do the same for the 14 on the right side. Instead, since the number is being subracted from 3a, we have to add it to both sides.

13 + 14 = 3a + 14 - 14.

27 = 3a

a = 9.

Answer:

The answer is 24

Step-by-step explanation:

What you can do is add all of the numbers (31 + 33 + 35 + 37 + 39)

[tex]31 + 33 + 35 + 37 + 39=175[/tex]

Then subtract 199 by 175

[tex]199-175=24[/tex]

To check add them all together

[tex]31 + 33 + 35 + 37 + 39+24=199[/tex]

-The Relationship:

Both [tex]\angle 2[/tex] and the [tex]18\textdegree[/tex] angle are supplementary.

The measure of [tex]\angle 2[/tex]:

[tex]\angle 2 = 162\textdegree[/tex]

Step-by-step explanation:

-The relationship about both [tex]\angle 2[/tex] and the [tex]18\textdegree[/tex] angle, is that they are supplementary, which they both add up to [tex]180\textdegree[/tex].

-To find the measure of [tex]\angle 2[/tex], you need to subtract [tex]18[/tex] from [tex]180[/tex] to get the actual angle measurement of [tex]\angle 2[/tex]:

Finding the measure of [tex]\angle 2[/tex]:

[tex]180 - 18 = 162[/tex]

[tex]\angle 2 = 162\textdegree[/tex]

So, now you have the measure of [tex]\angle 2[/tex] .

Answer:

a = 4.5 units

b = 7.5 units

Step-by-step explanation:

By using mean proportional theorem in the ΔACB,

ΔACB ~ ΔADC ~ ΔCDB

[tex]\frac{AD}{CD}=\frac{CD}{DB}[/tex]

[tex]\frac{8}{6}=\frac{6}{a}[/tex]

a = [tex]\frac{6\times 6}{8}[/tex]

a = 4.5

[tex]\frac{AB}{CB}=\frac{CB}{DB}[/tex]

[tex]\frac{(a+8)}{b}=\frac{b}{a}[/tex]

Since a = 4.5

[tex]\frac{4.5+8}{b}=\frac{b}{4.5}[/tex]

b² = 4.5 × 12.5

b = √56.25

b = 7.5 units

Therefore, a = 4.5 units and b = 7.5 units will be the answer.
