the sun shines on a flagpole, causing a shadow to be cast on the ground. the distance from the base of the pole to the tip of the shadow is 49 feet. at that time of day, the sun's rays make an angle of 38° with the ground. How tall is the flagpole?
Answer:
30.17feet high
Step-by-step explanation:
Given the following
the distance from the base of the pole to the tip of the shadow = 49feet (hypotenuse)
angle of elevation = 38°
Required
Height of the flagpole (opposite)
Using the SOH CAH TOA identity
Sin theta = opposite/hypotenuse
Sin 38 = H/49
H = 49sin38
H = 49(0.6157)
H = 30.17feet
Hence the flagpole is 30.17feet high

Answer:
It ends on the half circle
Step-by-step explanation:
You are looking at the base of each shape. It starts with a triangle so you go down. Then the base of that is a rectangle so you go down again and so on. Therefore your answer is a half circle.

The mean of a data set is 124. The mean absolute deviation is 38. What is the greatest possible number within the mean absolute deviation?
Answer:
Infinity
Step-by-step explanation:
The given parameters are;
The mean of the data, μ = 124
The mean absolute deviation = 38
The mean absolute deviation is given as follows;
[tex]Mean \ absolute \ deviation = \dfrac{\sum \left | X - \mu \right |}{N} = 38[/tex]
Where;
μ = Mean
X = Score
N = The number of scores
Therefore;
[tex]N \times 38 = \sum\limits_{i = 1}^N \left | X - \mu \right |} = \sum\limits_{i = 1}^N \left | X -124 \right |}[/tex]
When there are an infinite number of terms, N = ∞, the greatest possible number within the mean absolute deviation is therefore also infinite
[tex]\infty \times 38 = \sum\limits_{i = 1}^{\infty} \left | X - \mu \right |} = \infty[/tex]
[tex]Greatest \ possible \ value \ for \left | X - \mu \right |} = \infty[/tex]

find the area of the triangle below!!!
Answer:
[tex]104in^{2}[/tex]
Step-by-step explanation:
area of a triangle is just (b)(h)/2
(13)(16)/2
208/2
104 in squared
Answer:
104ft²
Step-by-step explanation:
formula for area of a triangle = [tex]A=\frac{bh}{2}[/tex]
where b = base length and h = height
The triangle shown has a base length of 16 ft and a height of 13 ft
Using this information we plug in the values into the formula
[tex]A=\frac{16*13}{2}\\16*13=208\\\frac{208}{2} =104\\A=104ft^2[/tex]
Hence, the answer is 104ft²

Answer:
Same y-intercept
Step-by-step explanation:
They have the same y-intercept of 2
look a y intercept is where the function crosses the y axis or when x is 0
In the chart y=2 when x =2 meaning a y intercept of 2
in the graph u can see the line going through the y intercept at (0,2)
So they have the same y-intercept

2y-6=6x how do i find y
Answer:
y=3x+3
Step-by-step explanation:
Let's solve for y.
2y−6=6x
Step 1: Add 6 to both sides.
2y−6+6=6x+6
2y=6x+6
Step 2: Divide both sides by 2.
2y /2 = 6x+6 /2
y=3x+3
brainliest please?Answer:
y=3x+3
Step-by-step explanation:
add 6 to both sides and then divide both sides by 2

Find a set of parametric equations for the rectangular equation.
t=7-x
y=1/x
a.x=7+t,y=1/(-t+7)
b.x=t-7,y=-1/(t+7)
c.x=7-t,y=-1/(t-7)
d.x=t-7,y=1/(t+7)
e.7+t,y=1/(t-7)
9514 1404 393
Answer:
c. x = 7-t; y = -1/(t -7)
Step-by-step explanation:
To find the parametric equation for x, use the equation for t and solve for x.
t = 7-x
x = 7 -t . . . . . . add x-t to both sides
__
To find the parametric equation for y, substitute the equation for x.
y = 1/x
y = 1/(7-t)
To make this match the available choices, we need to multiply numerator and denominator by -1.
y = -1/(t -7)
The parametric equations are ...
x = 7 -t; y = -1/(t -7) . . . . . . matches choice C
Answer: it is C

At 12:15, the end of the minute hand of a clock is 8 feet above the ground. At 12:30, it is 6.5 feet off the ground How long is the minute hand of the clock? And How high is the center of the clock from the ground
Answer:
Length of minutes hand= 1.5 feet
Height of the center of the clock from the ground= 8 feet
Step-by-step explanation:
At 12:15, the end of the minute hand of a clock is 8 feet above the ground.
At 12:15 the minutes hand is making a radius along the diameter of the clock which means it is at the center of the clock. In other the center of the clock is 8 feet above the ground.
At 12:30, it is 6.5 feet off the ground .
This tells length of the minutes hand the clock which is the distance from the ground minus the distance off the ground
= 8-6.5= 1.5 feet
The center of the clock is 8 feet from the ground.
The length of the minute hand is 1.5ft, the distance of the center of the clock from the ground is 8ft
To solve this problem, we have to apply logical reasoning here.
Length of the Minute HandTo calculate the length of the minute hand, we just have to subtract or find the difference between the minute and from the ground at 12:30 to the minute hand at 12:15.
This will give us
[tex]12:15 - 12:30 = 8 - 6.5 = 1.5ft[/tex]
Distance of the Center of the clock from the groundThe distance of the center of the clock from the ground can be gotten from the distance from the ground at 12:15. This is because at 12:15, the minute hand is at the same horizontal line with the center of the clock and this makes the distance of the center of the clock from the ground is 8ft.
From the above,
The length of the minute hand is 1.5ft The distance of the center of the clock from the ground is 8ftLearn more on clocks here;

The graph shows the daily sales goal of
a coffee shop. If the employees sell
20 cups of coffee, how many cups of tea
must they sell to meet their goal?
Answer:
25 cups of tea
Step-by-step explanation:
On the x-axis, we have the number of cups of coffee plotted against the number of cups of tea which are plotted on the y-axis to represent the daily sales goals.
From the graph, when 20 cups of coffee are sold (x = 20), a corresponding sales of 25 cups of tea (y = 25) would be sold as well to meet the sales goal.
Therefore, when employees sell 20 cups of coffee, 25 cups of tea must be sold to meet their goal.

Answer:
(x+3, y+2)
Step-by-step explanation:
choose a letter: let's use points A and A'
A: (-3, 3)
A': (0, 5)
the rule would be (x+3, y+2) because (-3+3, 3+2) = (0,5)
Try it on another point:
B: (-4, 0)
B': (-4+3, 0+2) = (-1, 2) which checks out!

Answer:
The answer is 729/64.
Step-by-step explanation:
I would first simplify the equation.
In the denominator, you can get rid of b^0 because that just equals 1.
For the a's in the numerator and denominator, you have to flip them so the exponents can be positive.
Equation: [tex](\frac{3ab^2}{2a^3})^2[/tex]
Now, you can subtract a and a^3. This would be 1/a^2.
Equation: [tex](\frac{3b^2}{2a^2})^2[/tex]
Now, you can square the whole equation.
Equation: [tex]\frac{9b^4}{4a^4}[/tex]
This is the simplified equation. Now you can plug in -2 and -3.
Equation: [tex]\frac{9(-3)^4}{4(-2)^4}[/tex]
Equation: [tex]\frac{9(81)}{4(16)}[/tex]
Equation: 729/64
