What is the area of ABC below? If necessary, round your answer to two decimal places.

Answers

Based on the given figure above, in order for us to find the area of the triangle, we need to find the value of the base first. So in finding the base, we are going to use the Pythagorean theorem. a2 + b2 = c2. Substitute the values.
(9.4)^2 + (23.2)^2 = c2
88.36 + 538.24 = c2
626.6 = c2
c= 25.03
Now that we have the base, let us proceed for the Area.
The formula for area would be A = 1/2 (b)(h)
Plug in the values.
A = 1/2(25.03)(7.9)
A= 1/2(197.74)
A= 98.87
Therefore, the area of figure ABC is 98.87.
Hope this answer helps.

Henry has 523 baseball cards. He buys 24 each month. What is a explicit rule for the number of baseball cards Henry has in n months?

Answers

To find your explicit rule, you would make your function (f(n)) equal to your change in cards per month (24) times your number of months (n) plus you initial number of cards (523). This creates the function f(n)=24n+523. What this is essentially doing is calculating the number of new cards bought in n months (24n) and adding it to your starting value (523) to get your new number of cards (f(n)).

Answer:

the answer is a_n= 24n+499 just took the test :)

Step-by-step explanation:

We have been given an radical expression. We are asked to simplify our given expression.

[tex]\sqrt{18x^4y^3}[/tex]

We can rewrite terms of our given function as:

[tex]\sqrt{18\cdot x^4\cdot y^3}[/tex]

[tex]\sqrt{2\cdot 9\cdot x^4}\cdot y^2\cdot y}[/tex]

[tex]\sqrt{2\cdot 3^2\cdot (x^2)^2\cdot y^2\cdot y}[/tex]

Using radical rule [tex]\sqrt[n]{a^n}=a[/tex], we will get:

A student gets paid to sell raffle tickets at the school basketball game. He earns $15 a day, plus an extra $0.25 for each raffle ticket he sells and $2 for each hour he works at the game. If d = days, r = raffle tickets, and h = hours, what function can he use to calculate his earnings?

Answers

answer is C

T = 15d +r/4 +2h

or

 you can write another way

T = 15d + 0.25r + 2h 

Answer: C. [tex]T=15d+\frac{r}{4}+2h[/tex]

Step-by-step explanation:

Let d = days, r = raffle tickets, and h = hours.

Given: A student earns in a day = $15

Then his earning in d days =$15d

Also, he earns for each riffle = $0.25

Then his earning in for r riffles =$0.25r

And , he earns for each hour he works at the game = $2

Then his earning for h hours = $2h

Then the function he can use to calculate his earnings is given by :_

[tex]T=15d+0.25r+2h\\\\\Rightarrow\ T=15d+\frac{1}{4}r+2h[/tex]

Answer:

B) 2[(x + 5)(x2 + 2)]

Step-by-step explanation:

Given: 2x^3 + 10x^2 + 4x + 20

Here 2 is a common factor, so we take it out and write the remaining terms in the parenthesis.

2(x^3 + 5x^2 + 2x + 10)

Now let's take (X^3 + 5x^2 +2x + 10), we group and factor them as follows:

(x^3 + 5x^2 + 2x + 10) = x^2(x+5) + 2(x + 5) = (x+5)(x^2 +2)

When we combine them, we get

2x^3 + 10x^2 + 4x + 20 = 2(x+5)(x^2 +2)

Therefore, the answer is B) 2[(x + 5)(x2 + 2)]

From 2000-2010 a city had a 2.5% annual decrease in population. If the city had 2,950,000 people in 2000, determine the city's population in 2008.

Answers

So you first need to find how much the population drops each year. For that you need to do 2.5%/10years which would be .25 then you would multiply by 8 to find for 2008 which you would get 2.Then you need to get 2% of 2950000. To do this you need to do 2,950,000*.02 which finally gives you 59,000 then you would subtract 2,950,000-59000 which the answer to this is 2,891,000! Hope it helps.

The population of the city in the year 2008 is 2409122.

Important information:

Initial population in 2000 is 2,950,000.Decreasing rate is 2.5%.Exponential formula:

According to the exponential decay formula:

[tex]f(t)=a(1-r)^t[/tex]

Where a is the initial value, r is the decay rate and t is the time period.

The difference between 2008 and 2000 is 8.

Substitute [tex]a=2950000, r=0.025, t=8[/tex] in the above formula.

[tex]f(8)=2950000(1-0.025)^8[/tex]

[tex]f(8)=2950000(0.975)^8[/tex]

[tex]f(8)=2409122.8208[/tex]

Round the value to the previous integer.

[tex]f(8)\approx 2409122[/tex]

Therefore, the population of the city in 2008 is 2409122.

two consecutive odd negative integers have a product of 483, find the integers ...?

Answers

Negative 21 and Negative 23 are the two integers you are looking for. Two negatives make a positive and the are both consecutive odd integers that = 483 when multiplied.
In order to find this you need to assume that they are declared as X and as X + 2. This makes the formula for calculating it x (x+2)=483, and this, based on the formulas for calculation, equals

 x^2+2x-83=0

From this we can see that a negative X is -23, which when +2 is added results in -21.

The axis of symmetry for the function f(x) = –2x2 + 4x + 1 is the line x = 1. Where is the vertex of the function located?

Answers

Answer:

(1, 3)

Step-by-step explanation:

You are given the h coordinate of the vertex as 1, but in order to find the k coordinate, you have to complete the square on the parabola.  The first few steps are as follows.  Set the parabola equal to 0 so you can solve for the vertex.  Separate the x terms from the constant by moving the constant to the other side of the equals sign.  The coefficient HAS to be a +1 (ours is a -2 so we have to factor it out).  Let's start there.  The first 2 steps result in this polynomial:

[tex]-2x^2+4x=-1[/tex].  Now we factor out the -2:

[tex]-2(x^2-2x)=-1[/tex].  Now we complete the square.  This process is to take half the linear term, square it, and add it to both sides.  Our linear term is 2x.  Half of 2 is 1, and 1 squared is 1.  We add 1 into the set of parenthesis.  But we actually added into the parenthesis is +1(-2).  The -2 out front is a multiplier and we cannot ignore it.  Adding in to both sides looks like this:

[tex]-2(x^2-2x+1)=-1-2[/tex].  Simplifying gives us this:

[tex]-2(x^2-2x+1)=-3[/tex]

On the left we have created a perfect square binomial which reflects the h coordinate of the vertex.  Stating this binomial and moving the -3 over by addition and setting the polynomial equal to y:

[tex]-2(x-1)^2+3=y[/tex]

From this form,

[tex]y=-a(x-h)^2+k[/tex]

you can determine the coordinates of the vertex to be (1, 3)

The diameter of the cylinder with a volume of 175 cubic units and a height of 7 units is 5 units.

To calculate the diameter of a cylinder, we first need to find the radius using the formula for the volume of a cylinder, V = πr²h. Given that the volume is 175 cubic units and the height is 7 units, the radius comes out to be 5 units. Since the diameter is twice the radius, the diameter of the cylinder is 5 units.

Justine enrolls in a music program. The cost of the program includes a one-time registration fee of $45 and a fee of $9 per lesson. If the average cost per music lesson is $12 and Justine has taken x classes, which equation represents this scenario?


A.12=54/x
B.12=45+9/x
C.12=45+9x/x
D.12=45x+9/x

Answers

If Justine has taken x classes of $9 per lesson, then the total fee for these lessons is $9x.

The cost of the program includes a one-time registration fee of $45 and a fee of $9 per lesson. This means that the total cost of the program in terms of x is

$45 + $9x = $(45 + 9x).

If the average cost per music lesson is $12 (includes a registration fee), then the cost of the program is $12x.

Therefore,

12x = 45 + 9x.

Divide this equation by x:

[tex]12=\dfrac{45+9x}{x}.[/tex]

Answer: correct option is C

The correct option is C) [tex]\[12 = \frac{45 + 9x}{x}\][/tex]. The equation that represents this scenario is [tex]\[12 = \frac{45 + 9x}{x}\][/tex].

To understand why option D is correct, let's break down the costs associated with Justine's music program.

1. The registration fee is a one-time cost of $45. This is a fixed amount and does not depend on the number of classes taken.

2. The cost per lesson is $9, and Justine has taken x classes. Therefore, the total cost for the lessons alone is 9x.

3. The average cost per music lesson, including the registration fee, is $12. This average cost is calculated by taking the total cost (registration fee plus the cost of x lessons) and dividing by the number of classes x.

4. The total cost for x classes, including the registration fee, is the sum of the registration fee and the cost of the lessons, which is [tex]\(45 + 9x\)[/tex].

5. To find the average cost per lesson, we divide the total cost by the number of classes x. This gives us the equation [tex]\(\frac{45 + 9x}{x}\)[/tex].

6. We know that the average cost per lesson is $12, so we set the equation equal to 12: [tex]\(12 = \frac{45 + 9x}{x}\).[/tex]

Therefore, the equation that correctly represents the scenario is: c)

[tex]\[12 = \frac{45 + 9x}{x}\][/tex].
