Answer:
3.75 or 3 3/4
Step-by-step explanation
Ok the denominators aren't the same so were going to make them the same by them changing into the same number.
we can do thins by timesing 5 by 4=20 and 4 timesing by 5=20
So now that the denominators are the same we have to times 1 by 4 since it denominator was times by same thing with 3 except that only get times by 5.
1 x 4=4 and 3 x 5=15 so now our two fractions are 15/20 and 4/20
15 divided by 4=3.75 and there's our answer.
we get the .75 because it is 3 more so 3 4 x3 =12 that's where we get 3 and then there is 3 left and 3/4 of and 3/4=0.75 and then you combined them to make 3.75.

Albeit cosine is undefined at , this discontinuity is evitable by canceling terms. The expression is equivalent to , which is continuous for all . According to this result, the student did not make a mistake. Answer was correct.
Answer:
See below
Step-by-step explanation:
Since [tex]cos(\frac{\pi}{2})=0[/tex], the denominator will be 0, and the result would be indeterminate.
Do not read on if you do not understand Calculus
However, notice that [tex]\lim_{x \to \frac{\pi}{2}} \frac{sin(2x)}{cos(x)}=2[/tex] by L'Hopital's Rule:
[tex]\lim_{x \to \frac{\pi}{2}} \frac{sin(2x)}{cos(x)}\\\\\frac{2cos(2x)}{-sin(x)}\\ \\\frac{2cos(2(\frac{\pi}{2}))}{-sin(\frac{\pi}{2} )}\\\\\frac{2cos(\pi)}{-1}\\ \\\frac{-2}{-1}\\ \\2[/tex]

¿cuanto pesa cada uno de nuestros 3 personajes?
niña+niño niño+perro niña+perro
51kg 46kg 41kg
Resolviendo el sistema de ecuaciones veremos que:
niña = 23kgniño = 28kgperro = 18kg.¿Como resolver el sistema de ecuaciones?
Aqui tenemos el sistema de ecuaciones:
Niña + niño = 51kg
Niño + perro = 46 kg
Niña + perro = 41kg
Para resolver esto, lo primero que debemos hacer es aislar una variable en una de las ecuaciones, por ejemplo, podriamos aislar "perro" en la tercera:
perro = 41kg - niña
Ahora reemplazamos eso en la segunda para obtener:
niño + (41kg - niña) = 46kg
niño - niña = 46kg - 41kg = 5kg
niño = niña + 5kg
Ahora logramos obtener la variable "niño" en terminos de la variable "niña". Podemos reemplazar esto en la primera ecuacion del sistema.
niña + niño = 51kg
niña + (niña + 5kg) = 51kg
2*niña = 51kg - 5kg = 46kg
niña = 46kg/2 = 23kg.
Ahora que sabemos esto, usamos las otras ecuaciones para encontrar el peso del niño y el perro:
niño = niña + 5kg = 23kg + 5kg = 28kg
perro = 41kg - niña = 41kg - 23kg = 18kg.

Angelina wants to prove that vertical angles are congruent. She uses the diagram below to formulate her proof.
Angelina has one step wrong in her proof. The steps of her proof are shown below. Mark the step that is INCORRECT.
A.
Linear pairs of angles are complementary, hence, m∠2 + m∠3 = 90°.
B.
Subtracting m∠3 from both sides of the above equation gives m∠2 = m∠4.
C.
In my proof, I used m∠2 + m∠3 = m∠3 + m∠4 to justify linear pairs.
D.
By definition of congruent angles, ∠2 ≅ ∠4. This will show that ∠2 and ∠4 are veritcal angles.
Answer:
Option (A)
Step-by-step explanation:
Correct proof to prove the vertical angles are congruent :
1). Linear pairs of angles are supplementary.
m∠2 + m∠3 = m∠3 + m∠4
2). By subtracting m∠3 from both the sides of the above equation.
3). By definition of congruent angles, ∠2 ≅ ∠4. This will show that ∠2 and ∠4 are vertical angles.
Therefore, Option (A) is incorrect in which Angelina showed that linear pairs of angles are complementary.
You have just arranged for a $1,760,000 mortgage to finance the purchase of a large tract of land. The mortgage has an APR of 7.6 percent, and it calls for monthly payments over the next 25 years. However, the loan has an eight-year balloon payment, meaning that the loan must be paid off then. How big will the balloon payment be?
Answer:
$1,500,257.38
Step-by-step explanation:
The balloon payment will be the balance on the loan after 8 years worth of payments have been made. The normal payment amount is the value calculated for a 25-year loan. A spreadsheet, financial calculator, or app can simplify this for you. In the attached, we have used the financial functions available on a TI-84 calculator.
The normal monthly payment will be $13,120.94.
After 8 years, the remaining balance will be $1,500,257.38. This is the size of the balloon payment.

Question 4 Part A (5 points):
Carlos started a business growing palm trees in South Florida.
The function t(s) = 3s + 20 represents the
number of palm trees that grew, where s is the
number of seeds he planted.
The function s(d) = 20d represents the number
of seeds he plants per day, where d represents
the number of days.
Write a composite function that represents
how many palm trees Carlos can expect to
grow over a certain number of days.
Answer:
t(d) = 60d + 20
where t(d) is the number of palm trees grown, and d is the number of days
Step-by-step explanation:
Given function:
t(s) = 3s + 20
where:
t(s) = number of palm trees growns = number of seeds plantedGiven function:
s(d) = 20d
where:
s(d) = number of seeds planted per dayd = number of daysTo determine the composite function that represents how many palm trees Carlos can expect to grow over a certain number of days, simply substitute s = 20d into t(s) = 3s + 20:
⇒ t(d) = 3(20d) + 20
⇒ t(d) = 60d + 20
where t(d) is the number of palm trees grown, and d is the number of days.
If Tim had lunch at $50.50 and he gave 20% tip, how much did he spend?
Answer:
Tim spent $60.60 for his lunch.Step-by-step explanation:
The tip is 20% of what he paid for lunch. Hence
tip = 20% of 50.50 = (20/100)*50.50 = 101/100 = $10.10
Total spent
50.50 + 10.10 = $60.60
So hence, Tim spent $60.60 for his lunch.

8r+12p-3p
I cant figure thia on out
Answer:
8r + 9p
Step-by-step explanation:
Combine like terms. Like terms are terms with the same variables as well as the same amount of said variable.
In this case, combine 12p with -3p
8r + 12p - 3p
8r + (12p - 3p)
8r + 9p
8r + 9p is your answer.
~
While adding such algebraic expressions, we combine the like terms which contains the same variables infact same degree of variables.
Given expression:
8r + 12p - 3pHere 12p and 3p are like terms because they are having same variable that is p. So, we can compute any operation like hear it's subtraction.
➝ 8r + (12p - 3p)
➝ 8r + 9p
Now no more like terms are there, So the final answer is 8r + 9p. And we are done!

3 and <4 are supplementary. If the m<3 = 13° what is the measure of <4?
Answer:
Well supplementary means that both the angles add up to 180
We know that the measure of angle 3 is 13 degrees.
The measure of angle 4 is unknown
And the total of angles 3 and 4 are 180.
So you can make an equation
13 + x = 180
Solve for x
x= 167
Measure of angle 4 is 167
m< 4 = 167 degrees

Find the value of w.
Answer:
w = 1
Step-by-step explanation:
y = [tex]x^{4}[/tex] + 4w²x³ - 11wx² - 30wx
if x = 3 , then y = 0
[tex]3^{4}[/tex] + 4w²( 3 )³ - 11w( 3 )² - 30w( 3 ) = 0
108 w² - 99 w - 90w + 81 = 0 ........ (1)
(1) ÷ 9
12w² - 21w + 9 = 0 ⇒ [tex]w_{1}[/tex] = 1 and [tex]w_{2}[/tex] = [tex]\frac{3}{4}[/tex]
"1" the value for w that match the graph.

The function shown on the graph has a greater rate of change and a higher starting point. O C. The function shown on the graph has a smaller rate of change, but a higher starting point D. The function shown on the graph has a smaller rate of change and a lower starting point.
The function shown on the graph has the same rate of change, but a higher starting point
Fine the diagram needed attached.
The rate of change of the line is the slope of the line. The standard equation of a line is expressed as y = mx + b;
m is the rate of change or slopeGiven the equation y = 5x + 5, the rate of change of the expression is 5.
For the given graph, the slope of the graph is expressed as:
(2, 4) and (0, -6)
m = -6-4/0-2
m =-10/-2
m = 5
