a cyclic quadrilateral is shown. x:y=3:7. work out the size of angle z

Answer:

A = 236,000 (1.04)^t

population in 2009 : 335,902 people

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential growth function:  

A = P (1 + r) t  

Where:  

p = original population  

r = growing rate (decimal form) = 4/100 = 0.04

t= years passed from 2000

A = population after t years  

Replacing with the values given:  

A = 236,000 (1+ 0.04)^t

A = 236,000 (1.04)^t

Population in 2009.

t = 2009-2000 = 9  

A = 236,000 (1.04)^9

A = 335,902 people

Answer:

4.5 ft

Step-by-step explanation:

Given that the two fugures in the question above are similar, it means they have the same shape, even though they are if different sizes, the ratio of their corresponding sides are proportional. Thus,

18/x = 8/2

Let's solve for x as required.

We have,

18/x = 8/2

=>Cross multiply:

18 × 2 = 8 × x

36 = 8x

=>Divide both sides by 8

36/8 = x

4.5 = x

x = 4.5 ft

The first option is our answer = 4.5 ft

Answer:

25, 26, 27

Step-by-step explanation:

78/3=26, so one number is 26 and the other numbers have to equal 52, so the numbers have to either be 24,25,27,28. 25+27=52,

The codes for each country are 25, 26 and 27.

Any positive or negative number without fractions or decimal places is known as an integer, often known as a "round number" or "whole number."

Let three consecutive integers are n-1, n, n+1.

Then,

the sum of three consecutive integers is 78.

According to the question,

n - 1  + n + n + 1 = 78

3n = 78

n = 26

The integers are 25, 26 and 27.

Therefore,  integers are 25, 26 and 27.

Answer: 12(X+8)=240

Step-by-step explanation: We then would have to do the distributive property and you end with 12x+96=240

Subtract 96 from each side

Then you end with

12x=144

You then divide 12 from each side and see that X=12!

Answer:

The distance between the two given complex numbers = 9

Step-by-step explanation:

Explanation:-

Step(i):-

Given  Z₁ = 9 - 9 i    and Z₂ = 10 -9 i

Let A and B represent complex numbers Z₁ and Z₂ respectively on the argand plane

⇒ A =  Z₁ = x₁ +i y₁ = 9 - 9 i and

    B = Z₂ = x₂+ i y₂ = 10 -9 i

Let (x₁ , y₁) = ( 9, -9)

     (x₂, y₂) = (10, -9)

Step(ii):-

The distance between the two points are

    A B   =   [tex]\sqrt{(x_{2} - x_{1})^{2}+(y_{2} - y_{1})^{2} }[/tex]

    A B =   [tex]\sqrt{(10 - 1)^{2}+(-9 - (-9))^{2} }[/tex]

   AB   = [tex]\sqrt{(9)^{2} +(-9+9)^{2} }[/tex]

  AB    =  √81 = 9

Conclusion:-

The distance between the two given complex numbers = 9

Answer:

[tex]\frac{-c+d}{b}[/tex]

Step by Step:

Step 1: Subtract c from both sides:

ab + c + (−c) = d + (−c)

ab = −c + d

Step 2: Divide both sides by b:

[tex]\frac{ab}{b} = \frac{-c+d}{b}[/tex]

Step 3: Simplify:

Answer:

each coat $15

Step-by-step explanation:

$78-$18 divided by 4 =15

hope this helps :)

Answer:

The answer is that each shirt and pair of pants costs 15$

Step-by-step explanation:

So you have 78$, and you already need to buy a backpack so then you have 60$ dollars because the backpack is 18$, and 2 shirts and 2 pairs of pants is 4 pieces of clothing in all, 60$ divided by 4 pieces of clothing equals 15$ per piece of clothing (78 - 18 = 60 divided by 4 = 15)

Answer:

Angle 2, angle 3 and angle 4 will measure 60°

Step-by-step explanation:

From the figure attached,

'l' and 'm' are parallel lines and 't' is the transverse line.

m∠1 = m∠2 = 60° [Vertical angles]

m∠1 = m∠3 = 60° [Corresponding angles]

m∠1 = m∠4 = 60° [Alternate exterior angles]

Therefore, angle 2, angle 3 and angle 4 will measure the same as angle 1.

Answer:

A)  -2/3

Step-by-step explanation:

To find the answer look at what it's asking you to do.  (f/g) means to divide f(x) by g(x).

[tex](f/g)(x)=\frac{2x}{x^2+2}[/tex]

Now you need to find (f/g)(-1).  Plug in -1 wherever there is an x and simplify.

[tex](f/g)(-1)=\frac{2*-1}{(-1)^2+2}\\ (f/g)(-1)=\frac{-2}{1+2}\\ (f/g)(-1)=\frac{-2}{3}[/tex]

Your answer is -2/3

Answer:

-8.5

Step-by-step explanation:

17/2 = 8.5

f = 8.5

f -1(17) = 8.5 -17 = -8.5

-8.5 is your answer

The value of [tex]f^{-1}(17)[/tex] is 2.

From the definition of function we know that if f(x) = y , where x and y are two real values having range of (-∝,+∝) , then

[tex]f^{-1}(y) = x[/tex]

Thus in the problem, it is given that f(2) = 17 .

Using the above identity, we can find the value of [tex]f^{-1}(17)[/tex]

∴  [tex]f^{-1}(17) = 2[/tex]

Answer:

Step-by-step explanation:

I think it is 3,347. Because the curb weight is just the car without humans

Given that the curb weight of a new car is = 3347 pounds

Now we have to find the correct choice for the given weight of the car.

Given value is in pound while the choices are in ton.

Units are different so first task will be to get same units.

We know that 1 ton = 2000 pound

so to convert 3347 pound into ton, we will divide 3347 by 2000 and get 1.6735 ton.

Which lies between 1 and 2.

Hence final answer will be (c) between 1 and 2 tons.

Answer:

(2 1/2, 0)

Step-by-step explanation:

In the picture attached, the complete question is shown.

f(x) = 2 1/2 - 3 1/3 * x

or

f(x) = 5/2 - (10/3)*x

f^-1(x) is the inverse of f(x), which is obtained replacing f(x) by x, and x by y, and solving for y, as follows:

x = 5/2 - (10/3)*y

(10/3)*y = 5/2 - x

y = (5/2)*(3/10) - x*(3/10)

y = (3/4) - (3/10)*x

f^-1(x) = (3/4) - (3/10)*x

at x-intercept, f^-1(x) = 0,

(3/4) - (3/10)*x = 0

(3/4) = (3/10)*x

x = (3/4)*(10/3)

x = 5/2 or 2 1/2
