Answer:
[tex]4m+20>50[/tex]
Step-by-step explanation:
Let m represent the amount of months that has passed.
Paulo started out with 20 coins.
Each month, he adds four more coins to his collection.
Therefore, the amount of coins added after m months will be given by 4m.
So, the amount of coins Paulo has total after m months can be given by:
[tex]4m+20[/tex]
We want to know when Paulo will have "more than" 50 coins in his collection. Therefore, we will use the "greater than" sign. Thus, our inequality will be:
[tex]4m+20>50[/tex]

5,430 is 181% of what number?
Answer:
3000
Step-by-step explanation:
5430=1.81x
solving for x, we take 1, which is equal to 100%, and divide it by 1.81 to get 1/1.81 or 0.55248618
multiply 1/1.81 by 5430 to get 3000
find the value of x in the isosceles triangle shown below
Answer:
A
Step-by-step explanation:
The segment from the vertex to the base , bisects the base at right angles
Then there are 2 right triangles with legs x and 4 and hypotenuse [tex]\sqrt{52}[/tex]
Using Pythagoras' identity in either of the 2 right angles
x² + 4² = ([tex]\sqrt{52}[/tex] )²
x² + 16= 52 ( subtract 16 from both sides )
x² = 36 ( take the square root of both sides )
x = [tex]\sqrt{36}[/tex] = 6 → A
the price of a sandwich decreases from $8 to $6 what is the percentage decrease in the price of the sandwich
Answer:
The percentage decrease is 25%.
Step-by-step explanation:
The difference in price is $2:
$8 - $6 = $2
Now to find the percentage decrease, we use the formula decrease in price divided by original price (or new/old) times 100:
2/8 * 100.
This equals 200/800 which is 25%.

Trigonometric functions: what are they?The first six essential trigonometric functions are used in trigonometry. These functions are trigonometric ratios. The sine function, cosine function, secant function, co-secant function, tangent function, and co-tangent function are the six basic trigonometric functions. The side ratio of a right-angled triangle is equivalent to the identities and functions of trigonometry. Trigonometric formulas are applied to the perpendicular side, hypotenuse, and base of a right triangle in order to calculate the sine, cosine, tangent, secant, and cotangent values.
as base/hypotenuse = cos x
and sin x = hypotenuse/perpendicular

Two cards are drawn from a standard deck of cards without replacement. Find the probability of drawing a heart and a club in that order
Given:
Two cards are drawn from a standard deck of cards without replacement.
To find:
The probability of drawing a heart and a club in that order.
Solution:
We have,
Total number of cards = 52
Number of cards of each suit (Spade, club, diamond, heart) = 13
The probability of drawing a heart card is:
[tex]P(Heart)=\dfrac{\text{Number of heart cards}}{\text{Total number of cards}}[/tex]
[tex]P(Heart)=\dfrac{13}{52}[/tex]
[tex]P(Heart)=\dfrac{1}{4}[/tex]
Now, the number of remaining card is 51. So, the probability of drawing a club card is:
[tex]P(club)=\dfrac{\text{Number of club cards}}{\text{Total number of remaining cards}}[/tex]
[tex]P(club)=\dfrac{13}{51}[/tex]
Using these probabilities, the probability of drawing a heart and a club in that order is:
[tex]P(\text{Heart and club})=P(\text{Heart})\times P(\text{Club})[/tex]
[tex]P(\text{Heart and club})=\dfrac{1}{4}\times \dfrac{13}{51}[/tex]
[tex]P(\text{Heart and club})=\dfrac{13}{204}[/tex]
Therefore, the required probability is [tex]\dfrac{13}{204}[/tex].

Clothing donations are collected to help a family in need. The function g(x) represents the number of items collected where x is the number of people who donated. Does a possible solution of (60,10) make sense for this function? Explain yojr answer
Answer:
No g(x) = x/6 for (60, 10) to be a possible solution
by this function 60 people would have to donate 1/6th of a garment each to achieve 10 full garments
Step-by-step explanation:
g(x) number of items
x number of people
the data point (60, 10) make sense as a possilbe solution NO
g(x) = number of items x = 60 g(x) = 10
g(60) = x/6 = 10
= 60/10

a) The function is continuous in it's entire domain.
b) The increasing and decreasing intervals for the function are given as follows:
Increasing: (0,2).Decreasing: (2,10).What is the continuity concept?A function f(x) is continuous at x = a if it is defined at x = a, and the lateral limits are equal, that is:
[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]
In this problem, we have a piece-wise function which has the definition changing at x = 2, hence the continuity must be studied at x = 2.
The lateral limits for the function in this problem are defined as follows:
[tex]\lim_{x \rightarrow 2^-} A(x) = \lim_{x \rightarrow 2} x^2 + 2 = 2^2 + 2 = 6[/tex][tex]\lim_{x \rightarrow 2^+} A(x) = \lim_{x \rightarrow 2} \frac{-3x + 30}{4} = 0.25(-3(2) + 30) = 6[/tex]The second limit is also equals to the numeric value at x = 2, due to the equal sign in the definition, hence the function is continuous at x = 2 and for all other values in the domain.
The intervals of increase and decrease are given as follows:
Increasing: (0,2). -> y = x² increases for x > 0, the 2 changes just the range.Decreasing: (2,10). -> decreasing line, due to the negative slope.TranslationThe function for this problem is the piece-wise function A(x).
Item a asks if the function is continuous.

What is the equation of the
function y = x translated 3 units
up and 4 units left?
Answer:
Step-by-step explanation:
y=(x+4)+3
Answer:
y = x + 7
Step-by-step explanation:
Since y = x is a linear function, it may be confusing when using the translation tips you learned from class to solve it. However, there is an easy way to go about it.
1. Remember that when a function moves left, we use + inside of the parenthesis.
4 units left:
y = (x + 4)
2. Remember that when a function moves up, we use + outside of the parenthesis.
3 units up:
y = (x + 4) + 3
3. Add 'em up
y = x + 7
Since the function is linear, it may be confusing to see whether the graph moved up or left. However, by following the origin (0,0) of y = x and moving 4 units left and 3 units up, you will see that the origin has moved from (0,0) to (-4, 3), representing 4 units to the left and 3 units up on a graph.

In the graph of a quadratic function with vertex (2, -4) is shown in the figure, the Domain: -∞ < x < ∞ and Range: -4 ≤ x < ∞.
What is quadratic function?When a polynomial function has one or more variables and the highest exponent of any one of the variables is two, the function is said to be quadratic function.
A polynomial of degree 2 is referred to as such because the highest degree term in a quadratic function is of second degree. There must be at least one second-degree term in a quadratic function. This function is algebraic.
Domain for this quadratic function is all possible values of x where function is defined.
Thus, Domain: -∞ < x < ∞
Range is the set of value functions that correspond to the value 'x.'
Range: -4 ≤ x < ∞
