Answer:
It will take 4.4 years to gain $8000.
Step-by-step explanation:
Substitute the values in the formula.
A = P (1+r/n) nt 8000 = 6000 (1+0.06/12) 12t
Use BEDMAS (order of operations) and solve the value in the brackets.
8000 = 6000 (1.005) 12t
Divide both sides by 6000
1.3 = (1.005) 12t
Take the logarithm of both sides.
log (1.3) = log (1.005) 12t
Include the exponent in the equation.
log (1.3) = (12t) (log 1.005)
Divide both sides by log 1.005.
(log(1.3))/(log(1.005)) = 12t
Find out the log.
52.6039 = 12t
Divide both sides by 12.
4.4 = t

How far up the house would a ladder be resting if it is 25 ft long and 3 ft
away from the house? Round to the nearest tenth if necessary.
5.3 ft
21 ft
24.8 ft
25.2 ft
Answer:
C
Step-by-step explanation:
The last one is absurd. You can't have a ladder reaching higher than itself. The question is a Pythagorean problem.
Givens
a = 3
b = ?
c = 25 feet
Formula
a^2 + b^2 = c^2
Solution
3^2 + b^2 = 25^2
9 + b^2 = 625 Subtract 9 from both sides.
b^2 = 625 - 9
b^2 = 616 Take the square root of both sides.
b = sqrt(616)
b = 24.8

In a lab, 450 cells are present at the beginning of an experiment. The number of cells increased by 18% each hour. a) Write an exponential growth model giving the number of cells y present t hours after starting the experiment. b) Estimate the time when the number of cells is 1,030.
Answer:
Step-by-step explanation:
y = 450 × 1.18^t
:::::
450 × 1.18^t = 1,030
1.18^t = 1,030/450 = 103/45
t×ln(1.18) = ln(103/45)
t ≈ 5 hours

unless there is a value for x then that is all i can do
hope this helps:)
Answer: 10x - 8
Step-by-step explanation:
(7x - 3) -(5-3x)
= (7x - 3) - 5 + 3x Made them without parentheses. For -(5-3x), because there are - in front them, which means to multiply -1, so it become -5+3x.
= 7x - 3 - 5 + 3x
= 7x + 3x - 3 - 5
= 10x - 8

can you begin solving x-2/x+3 ≥2 by multiplying both sides of the inequality by x+3? Explain your answer.
Answer:
yes, but there is a better way
Step-by-step explanation:
instead of multiplying x+3 on both sides, I would instead subtract 2 on both sides. If you do this, it would be easier to write this equation in standard form and find the intervals.
In summary, to solve the inequality (x - 2)/(x + 3) ≥ 2, we can multiply both sides of the inequality by x + 3 only when x > -3 to preserve the direction of the inequality.
To solve the inequality (x - 2)/(x + 3) ≥ 2, we need to consider the impact of multiplying both sides of the inequality by x + 3.
When multiplying both sides of an inequality by a positive number, the direction of the inequality remains the same. However, if we multiply both sides by a negative number, the direction of the inequality is reversed.
In this case, the expression x + 3 is in the denominator of the left side of the inequality. If we multiply both sides of the inequality by x + 3, we need to consider two scenarios:
If x + 3 is positive: In this case, we can multiply both sides of the inequality by x + 3 without changing the direction of the inequality.
If x + 3 is negative: Multiplying both sides of the inequality by x + 3 would require flipping the direction of the inequality.
Therefore, we need to ensure that x + 3 is positive before multiplying both sides by x + 3 to preserve the direction of the inequality.
To determine when x + 3 is positive, we set the denominator equal to zero and solve for x:
x + 3 = 0
x = -3
So, if x > -3, then x + 3 is positive.
In summary, to solve the inequality (x - 2)/(x + 3) ≥ 2, we can multiply both sides of the inequality by x + 3 only when x > -3 to preserve the direction of the inequality.

Factor completely: 2x^3-12x^2+18x
Answer:
2x(x - 3)²
Step-by-step explanation:
We can simplify this a lot by first factoring 2x out of each term:
2x³ - 12x² + 18x
= 2x(x² - 6 + 9)
We can then factor the trinomial fairly easily, as it's a perfect square:
= 2x(x - 3)²
La profundidad de una alberca aumenta paulatinamente desde 0.80 metros hasta 3 metros en una longitud de 10 metros cual es el angulo de inclinacion de la alberca
Answer:
El ángulo de inclinación de la alberca es aproximadamente 12.407º.
Step-by-step explanation:
Puesto que conocemos la distancia horizontal ([tex]l[/tex]) y la variación en la profundidad ([tex]h[/tex]) de la alberca, en metros, podemos emplear la siguiente razón trigonométrica para calcular el ángulo de inclinación de la alberca ([tex]\alpha[/tex]), en grados sexagesimales:
[tex]\alpha = \tan^{-1}\left(\frac{h}{l} \right)[/tex] (1)
Si sabemos que [tex]l = 10\,m[/tex] y [tex]h = 2.20\,m[/tex], entonces el ángulo de inclinación de la alberca es:
[tex]\alpha \approx 12.407^{\circ}[/tex]
El ángulo de inclinación de la alberca es aproximadamente 12.407º.

Triangle DFE with coordinates D(0,0), F(3,0), and, E(3,1) is similar to triangle EHG. If vertex G has coordinates (9,3), what are the coordinates of vertex H?
Answer:
coordinates are (x,y)->(x+6,y+2)
F's coordinate is (3,0)
using the coordinates we get (9,2)
Therefore the coordinates are (9,2)
The required coordinates of vertex H are (6,2).
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.
Given that triangles DFE and EHG are similar.
This means that the ratios of the lengths of their corresponding sides are equal.
As per the question, we have:
DF/FH = DE/EG
Since DF = 3 and DE = 1, we can set up the following equation to find the length of FH:
FH = EG × (DF/DE)
Substituting the known values, we get:
FH = EG × (3/1)
As we know that EG = 6, we can substitute this value to find that FH = 18.
The coordinates of F are (3,0) and the coordinates of H are (x,y), we can set up the following equations to find the values of x and y:
x - 3 = 18
y - 0 = 2
Solving these equations, we find that x = 21 and y = 2.
Thus, the coordinates of vertex H are (6,2).
