Step-by-step explanation:
You want to use a trig identity. You have the side opposite, O and the side adjacent A, therefore use tangent:
[tex]tan(x)=\frac{O}{A}[/tex]
Substitute in your values and solve:
[tex]tan(30)=\frac{x}{5}[/tex]
[tex]x=\frac{5\sqrt{3} }{3}[/tex] or 2.9

Una pared rectangular tiene un perímetro de 48 metros. El largo de la pared es el doble del ancho. ¿Cuántos metros cuadrados de papel decorativo se necesitarán para empapelar toda la pared?
Answers
Perímetro = 48m
Ancho = x
Largo = 2x
Área = (2x)(x)
Ecuación:
2x + 4x = 48
6x = 48
x = 48/6
x = 8
Sustitución:
Área = [2(8)](8)
Área = (16)(8)
Área = 128
Respuesta: Se necesitarán 128 metros cuadrados de papel decorativo

Answer:
Estimate (eye-ballin'): around (3, 3)
Calculation: (2.6, 3.2)
Step-by-step explanation:
Given:
4x + 3y = 20
y = 2x - 2
Sophia's strat is absolutely correct. She makes two equations into one. This is called "substitution":
- Insert y of 2nd equation as y in 1st equation:
4x + 3(2x - 2) = 20
**Remember to multiply the entire thing by 3**
4x + 6x - 6 = 20
**Solve for x**
10x - 6 = 20
10x = 26
x = 2.6
Now that we have x, just plug it into any equation to find y (hint 2nd is easier):
y = 2(2.6) - 2
y = 3.2
COORDS: (2.6, 3.2)

Answer:
y = [-½]x + [-5]
Step-by-step explanation:
Equation describing how x and y are related can be written in slope-intercept form, y = mx + b.
m = slope = ∆y/∆x
Using two pairs of values from the table, (-2, -4) and (0, -5),
Slope (m) = (-5 - (-4))/(0 - (-2)) = -1/2
m = -½
b = y-intercept = the value of y when x is 0 = -5
b = -5
✔️To write the equation, substitute m = -½ and b = -5 into y = mx + b
Thus:
y = [-½]x + [-5]

A school increases its intake by 10%. if it starts with 1000 students, how many will it have at the beginning of the fourth year of expansion?
Answers
Answer:
1464 Students
Step-by-step explanation:
10% increase of 1000 = 1100 year 1
10% increase of 1100 = 1210 year 2
10% increase of 1210 = 1331 year 3
10% increase of 1331 = 1464 year 4
Graph g(x) = x2 +2 Compare the graph to the graph of f(x) = x2.
Answers
Step-by-step explanation: Remember that the parent graph f(x) = x², is a parabola that opens up and passes through the origin.
Notice that g(x) = x² + 2 has 2 added to the parent term.
This means that g(x) = x² + 2 is the graph of f(x) = x² translated two units up.

Answer:

Step-by-step explanation:
its the 4th
The polynomial example of a cubic monomial is option D 5x³.
What are terms in polynomials?The polynomial are mathematical expressions involving variables raised with non negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non negative exponentiation of variables involved.
Terms are added or subtracted to make a polynomial. which are composed of variables and constants all in multiplication.
Example as 3x +5 is a polynomial consisting 2 terms as 3x and 5
Since we know that if there is one term, the polynomial will be called monomial.
If there are two terms, the polynomial will be called binomial and If there are three terms, the polynomial will be called trinomial
Therefore, we can see that 5x³ is cubic monomial.
