Answer:
11 + 7n
Step-by-step explanation:
Here, we want to write an equation that represents the the number of coins deposited after the nth day
Mathematically,
there are 11 coins
We now proceed to add;
7 * n = 7n to what we have
So finally to get the number of coins , we add up
That will be:
11 + 7n

Hiking The scatter plot shows a hiker's elevation above sea level during a hike
from the base to the top of a mountain. The equation of a trend line for the
hiker's elevation is y = 7.81x + 672, where x represents the number of minutes
and y represents the hiker's elevation in feet. Use the equation of the trend line
to estimate the hiker's elevation after 155 minutes.

which number line shows the solution of 5x - 25 greater than -15
Answer:
you need to add number lines, but if you want the equation to be written and solved, then...
Step-by-step explanation:
5x - 25 > -15
+25 +25
5x > 10
divide both sides by 5
x > 2

[tex]\frac{x^2}{3}-\frac{1}{2}=\frac{x}{3}[/tex]
Because there are 3 and 2 as the denominators. Find the lowest number that both 3 and 2 can divide without any quotients, which is 6.
Multiply all whole equation by 6.
[tex]\frac{x^2}{3}(6)-\frac{1}{2}(6)=\frac{x}{3}(6)\\2x^2-3=2x[/tex]
We should get like this. Then move 2x to subtract.
[tex]2x^2-2x-3=0[/tex]
Because the polynomial is a two-degree and a quadratic equation. We solve the value of x by either factoring, using the formula or completing the square.
But I'll use the Quadratic Formula instead as the factoring doesn't seem to work for the Quadratic Equation with square root answers.
[tex]x=\frac{-b±\sqrt{b^2-4ac} }{2a}[/tex]
This is the formula of Quadratic Equation. Ignore the weird letter as it just randomly appears and can't be deleted.
[tex]x=\frac{-(-2)±\sqrt{(-2)^2-4(2)(-3)} }{2(2)} \\x=\frac{2±\sqrt{4+24} }{4} \\x=\frac{2±\sqrt{28} }{4}\\x=\frac{2±2\sqrt{7} }{4} \\x=\frac{1±\sqrt{7} }{2}[/tex]
Therefore, the answer is x = (1±√7)/2

Answer:
20 units squared
Step-by-step explanation:
Using pythagorean theorum, we can find the hypotenuse(the long side). [tex]\sqrt{2^2 + 4^2} = \sqrt{20}[/tex]. Since the area of a square is one of the sides multiplied by itself, we get 20 units squared

Step-by-step explanation:
The coordinates of three of the vertices of a rectangle PQRS are P(-2, 2), Q(4, 2), and R(4, -3). A. Find the coordinates of point S, the fourth vertex of rectangle PQRS. B. What is the perimeter of the rectangle PQRS?
Answer:
The coordinates are (x,y) (-2,-3)
Step-by-step explanation:
We need to take note of the following properties.
1. A rectangle has 4 sides.
2. Two opposite sides of a rectangle are equal.
Coordinates of the triangle on the graph: P(-2, 2), Q(4, 2), R(4, -3) and S(x,y)
The length of the triangle:
We can get this from the x -coordinates of P and Q
Length = |-2 - 4| = 6 (We are only taking positive values for dimensions. You cannot have a negative length)
Recall that the length of the two sides is equal. Therefore, we can relate the length of the second side to its coordinates using the coordinates of R and S
x = 4-6; x = - 2
The breadth of the triangle
We can get this from the y -coordinates of Q and R
Breadth = |-3 -2| = 5 (We are only taking positive values for dimensions. You cannot have a negative breadth)
Recall that the breadth of the two sides is equal. Therefore, we can relate the breadth of the second side to its coordinates using the coordinates of R and S
2 - y = 5; y = -3
Therefore the coordinates are (x,y) (-2,-3)
What is f(3) if f(x) = 2x + 1?
Answer:
f(3) = 7
Step-by-step explanation:
To evaluate f(3), substitute x = 3 into f(x), that is
f(3) = 2(3) + 1 = 6 + 1 = 7

A princess is standing 38 feet from the base of a 217 foot tall tower. What is the angle of elevation from him to the ogre who has his princess held captive
Answer:
Angle of elevation = 80°
Step-by-step explanation:
A princess is standing 38 feet from the base of a 217 foot tall tower. What is the angle of elevation from him to the ogre who has his princess held captive?
To solve for angle of elevation, we use the Trigonometric function of Tangent.
tan θ = Opposite side/Adjacent side
Opposite side = Height of the tower = 217 ft
Adjacent side = 38ft
tan θ = 217/38
tan θ = 5.6315789474
θ = arc tan 5.6315789474
= 79.930937301°
Approximately = 80°

A shopkeeper buys 10 television sets from a retailer at a rate of Euro 15,000 per set. He sells half of them at a profit of 25 % and rest half at a loss of 20%. Find the overall profit/loss faced by the shopkeeper.
Answer: Profit of $3,750
Step-by-step explanation:
Sold half of the sets at a profit of 25%;
= (15,000 * 5 sets) * 25%
= $18,750
Sold the other half at a loss of 20%;
= (15,000 * 5) * 20%
= $15,000
Profit (loss) = 18,750 - 15,000
= $3,750
