Step-by-step explanation:

Answer:

interior angle sum = (Number of sides x 180°) - 360°

interior angle sum = (6 x 180°) - 360° = 720°

∠CDE = (720° - 90° - 90°)/4 = 135°

I think the third once because is Making criss-cross

Answer:

5

Step-by-step explanation:

7^2 = (2(6)^1/2)^2 + BC^2 (Pyth. theorem)

BC = 5

Answer:

its supposed to be 6.08 but we can take of..08 so 6

Step-by-step explanation:

[tex]a + b = c \\ ( 2 \sqrt{6} ) {}^{2} + {b}^{2} = {7}^{2} \\ 2 \times 6 + {b}^{2} = 49 \\ {b}^{2} = 49 - 12 \\ {b }^{2} = 37 \\ \sqrt{b} {}^{2} = \sqrt{37} \\ b = 6.08 \: or \: 6[/tex]

Answer:

hello your question is incomplete attached below is the complete question

answer : The vertical asymptote is not relevant since a negative population holds no relevance ( option 3 )

Step-by-step explanation:

attached below is the Graph of P(x) plotted using online tools as part of the solution requested by the question

From the attached graph vertical asymptote is x  = 0

Also from the graph the x-intercept is (2, 0) which means that whenever  a lie is told twice, Nobody believes the lie ( i.e. y = 0 when x = 2 )

Answer:

84 minutes

Step-by-step explanation:

45:54

70:x

45/54=70/x

45x=70x54         - cross multiply

x=70x54/45        - divide by 45

x=84

Answer:

1/2

Step-by-step explanation:

area of larger square: 12 x 12 = 144

area of smaller square: 6√2 x 6√2 = 72

S/B = 72/144 = 1/2

Answer: 2

Step-by-step explanation:

Let's substitute the number as x in the equation.

Triple means you multiply it by 3.

Then you add four, and get 10.

We can write that like this:

3x + 4 = 10

Then subtract 4 from both sides:

3x = 6

And then divide both sides by 3:

x = 2

So the number is 2.

Answer:

[tex]\sqrt{\frac{(8b^2-9a^2)^2}{576a^2}-\frac{2b^2+5ab+2a^2}{12a} } -\frac{8b^2-9a^2}{24a} \\\\or\\-\sqrt{\frac{(8b^2-9a^2)^2}{576a^2}-\frac{2b^2+5ab+2a^2}{12a} } -\frac{8b^2-9a^2}{24a}[/tex]

Step-by-step explanation:

The quadratic formula for

[tex]ax^2+bx+c=0[/tex]

the solution is: (-b±√(b²-4ac))/(2a)

The solution is:

[tex]\sqrt{\frac{(8b^2-9a^2)^2}{576a^2}-\frac{2b^2+5ab+2a^2}{12a} } -\frac{8b^2-9a^2}{24a} \\\\or\\-\sqrt{\frac{(8b^2-9a^2)^2}{576a^2}-\frac{2b^2+5ab+2a^2}{12a} } -\frac{8b^2-9a^2}{24a}[/tex]

The difference:

Answer:

Step-by-step explanation:

CA and CB are both opposite equal 90 degree angles so are equal so we can say

8x-12=4x

4x-12=0

4x=12

x=3, since CA=4x

CA=4(3)=12

Answer:

4x - 5 = 24

x= 7.25

Step-by-step explanation:

4x - 5 = 24

4x= 24 + 5

x = 29 / 4 = 7.25

I hope im right!!

Answer:

[tex]Average = 30[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 4^{x - 1} + 2[/tex]

Required

Average [tex]rate\ of\ change[/tex] from 2 to 4

This is calculated using:

[tex]Average = \frac{f(b) - f(a)}{b - a}[/tex]

Where

[tex]a= 2[/tex]  and  [tex]b = 4[/tex]

So:

[tex]Average = \frac{f(4) -f(2)}{4 - 2}[/tex]

[tex]Average = \frac{f(4) -f(2)}{2}[/tex]

Calculate f(2) and f(4)

[tex]f(x) = 4^{x - 1} + 2[/tex]

[tex]f(2) = 4^{2-1} + 2[/tex]

[tex]f(2) = 4 + 2[/tex]

[tex]f(2) = 6[/tex]

[tex]f(4) = 4^{4-1} + 2[/tex]

[tex]f(4) = 4^3 + 2[/tex]

[tex]f(4) = 66[/tex]

So:

[tex]Average = \frac{f(4) -f(2)}{2}[/tex]

[tex]Average = \frac{66 - 6}{2}[/tex]

[tex]Average = \frac{60}{2}[/tex]

[tex]Average = 30[/tex]

Answer below (dont flag people if they dont get it right, that's just messed up).

Step-by-step explanation:

The scale factor is 1.5

Answer:

x=-5 & y=-2

Step-by-step explanation:

Step 1: Solve y=x+3 for y:

y=x+3

Step 2: Substitute x+3 for y  in 3x-4y =-7:

3x-4y=-7

3x-4(x+3)=-7

-x-12=-7 (Simplify both sides of the equation)

-x-12+12=-7+12 (Add 12 to both sides)

-x=5

-x/1=-5/-1 (Divide both sides by -1)

Step 3: Substitute -5  for x in y=x+3:

y=x+3

y=-5+3

y=-2 (Simplify both sides of the equation)

x=-5 and y=-2
