A flag pole has a rope that attaches to the ground from the top of the flagpole the rope create a 30° angle with the ground and is attached 10 m from the bottom of the pool how long is the rope in how tall is the flagpole
Answer:
[tex]5.77\ \text{m}[/tex]
[tex]11.54\ \text{m}[/tex]
Step-by-step explanation:
p = Height of pole
h = Length of role
b = Distance between the bottom of the rope and bottom of the pole = 10 m
[tex]\theta[/tex] = Angle between the rope and the ground = [tex]30^{\circ}[/tex]
[tex]\tan\theta=\dfrac{p}{b}\\\Rightarrow p=b\tan\theta\\\Rightarrow p=10\tan30^{\circ}\\\Rightarrow p=5.77\ \text{m}[/tex]
The length of the rope is [tex]5.77\ \text{m}[/tex]
[tex]\cos\theta=\dfrac{b}{h}\\\Rightarrow h=\dfrac{b}{\cos\theta}\\\Rightarrow h=\dfrac{10}{\cos30^{\circ}}\\\Rightarrow h=11.54\ \text{m}[/tex]
The length of the pole is [tex]11.54\ \text{m}[/tex]
h(x)=-5(x-1)^2+45
what is the maximum height
9514 1404 393
Answer:
45
Step-by-step explanation:
The equation is that of a parabola in vertex form.
y = a(x -h)^2 +k
where 'a' is the vertical scale factor and (h, k) is the vertex.
Comparing this to the given function, you find ...
a = -5
h = 1
k = 45
The negative value of 'a' tells you the parabola opens downward, so the y-value of the vertex is the maximum value of the function: 45.

simotenus equation
Answer:
I think there is an error in the question, I assume it reads:
4x+2y=20
x+3y=50
If not, please make appropriate corrections to the question.
Answer: x=-4, y=18
Step-by-step explanation:
4x+2y=20
Simplify, divide by two,
2x+y=10.....................(1)
x+3y=50....................(2)
Multiply (2) by 2
2x+6y=100 ....................(2a)
Subtract (1) from (2a)
2x+6y - (2x+y) = 100 - 10
5y = 90
y=18..............................(3)
Substitute (3) into (1)
2x+(18)=10
2x = 10-18 =-8
x=-4 ............................(4)
Substitute (3) and (4) into (1) for verification
2x+y = 2(-4)+18 = 18-10 = 10 checks.
Substitute (3) and (4) into (2) for verification
x+3y=-4+3(18) = -4+54 = 50 checks.
Have a nice day!

Deondre drops a nickel from a balcony that is 125 meters in the air. The function y=-5t+125 can be used to represent y, the height of the coin in meters after t seconds. Write and solve an equation to find the time it will take for the coin to hit the ground.
The time it will take for the coin to hit the ground is 5 seconds for the given function.
What is distance?Displacement and distance are terms used to describe how an object or person moves, but they have different meanings.
No matter where anything starts or ends, distance describes how much ground it has travelled. It is a scalar quantity with units like metres, kilometers, miles, etc. for measurement.
On the other hand, displacement describes a change in an object's or a person's location from their original position to their end position, including direction. Since it has both magnitude (the distance) and direction, it is a vector quantity. Displacement can be positive or negative depending on the direction of movement and is measured in units like metres, kilometers, miles, etc.
The given equation is y=-5t² +125.
When the coin hits the ground the value of y = 0 thus,
y = -5t² + 125
0 = -5t² + 125
5t² = 125
t² = 25
t = ±5
Hence, the time it will take for the coin to hit the ground is 5 seconds.

A negative number is always = the absolute value of a number
Answer:
To find the absolute value of an negative number, just take away the negative sign
The absolute value of a number can NEVER be negative
Step-by-step explanation:
For example, to find the absolute value of -22, it would be 22, since it is 22 points away from zero. To find the absolute value of -99.9, it would be 99.9.
A negative number is NOT always the absolute value of a number.
For example, the absolute value of 34 is, 34. If you plot it on a number line, it is 34 points away from zero, therefore proving a negative number is NOT always the absolute value of a number.
The absolute value of a number can NEVER be negative.
Answer:
The absolute value of a number is always POSITIVE! To find the absolute value, all you need to do is take away the negative sign!
