Find the one arithmetic means between a and b

Step-by-step explanation:

Answer:

Step-by-step explanation:

The vertex form of an equation of the parabola:  

                                                       f(x) = a(x - h)² + k

the vertex is (7, -4)  ⇒   h = 7,  k = -4

so:

     f(x) = a(x - 7)² + (-4)

    f(x) = a(x - 7)² - 4

The parabola goes through the point (5, 8) ⇒   x=5,  f(x)=8

8 = a(5 - 7)²  - 4

8 = a(-2)²  - 4

+4           +4

12  = 4a

÷4       ÷4

a = 3

It means the equation of the parabola in vertex form:

                               f(x) = 3(x - 7)² - 4

Answer:

Yes.

RS ≅ PS

QS ≅ QS

Step-by-step explanation:

The Hypotenuse-Leg Congruence Theorem states that when the hypotenuse and one leg of a Right-angled triangle are congruent to that of another Right-angled triangle, the two Right-angled triangles are therefore congruent.

In the diagram given, the hypotenuse (RS) and a leg (QS), of ∆RQS is congruent to the hypotenuse (PS) and a leg (QS) of ∆PQS. Therefore, ∆PQS is congruent to ∆RQS by HL Congruence Theorem.

Yes, PQS congruent to RQS by HL is true statement according to the diagram.

Hence :

RS ≅ PS

QS ≅ QS

Step-by-step explanation:

Given information:

The hypotenuse RS and PS

And leg QS.

Hypotenuse-Leg (HL) theorem:

The H-L theorem states that If, the hypotenuse and one leg of a Right-angle triangle are congruent to that of another right angle triangle then the given two right angled triangle will be congruent.

As, we can see in the given diagram the hypotenuse (RS) and the leg (QS) of triangle ΔRQS is congruent to hypotenuse (PS) and leg (QS) of triangle ΔPQS.

Hence , we can say that the ΔPQS is congruent to ΔRQS by H-L Congruent theorem.

Answer:

1. $1050

2. $5.25t = c.

3. $813.75 ÷ 5.25 = 155.

Step-by-step explanation:

For the first day, 200 kid tickets were purchased. We know that a singular movie ticket is $5.25. From this information, I know I have to multiply.

200 x 5.25 = 1050.

The answer to number one is $1050.

So t will be the variable that represents the number of kid's tickets and c is the total cost, from this equation, I would create this equation:

$5.25t = c.

I put 5.25 down because that is the cost of a singular child ticket. It would be multiplied by t (total amount of child tickets) and the product would be the total cost of those tickets (c).

The answer to number 2 is $5.25t = c.

Another day, the total cost of the tickets were $813.75. One kid movie ticket is $5.25, so this calls for division.

$813.75 ÷ 5.25 = 155.

The total amount of tickets that were purchased that day was 155 child tickets.

The total amount of tickets that were purchased that day was; 155 child tickets.

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that 200 kid tickets were purchased. We know that a singular movie ticket is $5.25.

200 x 5.25 = 1050.

The total cost of those tickets is $1050.

Let t be the variable that represents the number of kid's tickets and c is the total cost, from this equation:

$5.25t = c.

Now multiplied by t (total amount of child tickets) and the product would be the total cost of those tickets (c).

The answer is $5.25t = c.

On another day, the total cost of the tickets was; $813.75. One kid movie ticket is $5.25 thus;

$813.75 ÷ 5.25 = 155.

The total amount of tickets that were purchased that day was; 155 child tickets.

Step-by-step explanation:

Just plug in what x is.

h(-4) = 4(-4) + 1

h(-4) = -16 + 1

h(-4) = -15

h(-3) = 4(-3) + 1

h(-3) = -12 + 1

h(-3) = -11

h(1) = 4(1) + 1

h(1) = 4 + 1

h(1) = 5

h(2) = 4(2) + 1

h(2) = 8 + 1

h(2) = 9

h(3) = 4(3) + 1

h(3) = 12 + 1

1+2/3m+2=2+1/6

We move all terms to the left:

1+2/3m+2-(2+1/6)=0

Domain of the equation: 3m!=0

m!=0/3

m!=0

m∈R

We add all the numbers together, and all the variables

2/3m+1+2-(1/6+2)=0

We add all the numbers together, and all the variables

2/3m+3-(1/6+2)=0

We get rid of parentheses

2/3m+3-2-1/6=0

We calculate fractions

There is no solution for this equation

Answer: m = 1/10

Step-by-step explanation:

1 2/3m + 2 = 2 1/6

Firstly, subtract 2 from both sides to get m alone:

1 2/3m = 1/6

Now, to get m alone, divide both sides by 1 2/3:

m = 1/10

Answer:

4640933300 people would have died  from AIDS in 2006.

Step-by-step explanation:

Let the equation that models the growth in mortality because of AIDS be,

[tex]A_n=A_0(1+r)^n[/tex]

Where [tex]A_n[/tex] = Number of deaths after n years

[tex]A_0[/tex] = Deaths in first year

(1 + r) = Growth factor

n = number of years

Now we substitute the values in the equation,

[tex]A_0=1800[/tex]

(1 + r) = 1.9

n = Number of years = 2006 - 1983 = 23 years

[tex]A_n=1800(1.9)^{23}[/tex]

     = 1800(2578296.28)

     = 4640933300

Therefore, with the same death rate 4640933300 people would have died  from AIDS in 2006.

Step-by-step explanation:

If the lake's level rose 4 inches and in June it rose 2 more inches, the total amount of distance that he rose is (4+2).

Also if the lake's level fell 5 inches in July and 3 more inches in August as a result of no rain, then the total amount of fall will be (5+3).

Change in height of the lake = total rise in distance - Total fall in distance

Change in height of the lake = (4+2) - (5+3) = (5+3) - (4+2) {commutative law}

open the parenthesis

(4+2) - (5+3)= 4+2-5-3 (note that minus times plus will give minus)

Hence the expressions that best describe this situation are;

1.  (4+2) - (5+3)

2. (5+3)-(4+2)

Step-by-step explanation:

$4200 - $50

= $4150

4150 divided by 45 = 92.222.......

92.222 is approximately 93

So you can purchase 92/93 tickets in total

Since tickets are physical things, I dont think you can approximate it but that's my answer

The maximum amount of adult tickets they can purchase are 92.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given are tickets at an amusement park that are $25 for children and $45 for adults. The Jones family has 4200 cash and they have two children.

Assume that they could purchase [n] number of adult tickets.

Cash remaining for adult tickets = 4200 - 2(25)

The total number of adult tickets that can be buyed are calculated as follows -

45n = 4200 - 2(25)

45n = 4200 - 50

45n = 4150

n = 4150/45

n = 92 (exact value)

Therefore, the maximum amount of adult tickets they can purchase are 92.
