the angle of a elevation of the top of a tree from an observer standing 10m away from the foot of the tree is 56°. Calculate the height of the tree.
Explain your answer pls,thx
Answer:
14.83 meters
Step-by-step explanation:
Given that :
Angle of elevation (α) = 56°
Distance between observer and foot of tree = 10 meter.
Height of tree =?
Using trigonometry :
The height (h) of the tree can be obtained using :
Tan α = opposite / Adjacent
Tan(56°) = h / 10
1.4825609 = h / 10
Multiply both sides by 10
1.4825609 * 10 = h
14.8256 = h
Hence, the height of the tree is 14.83 m(2 decimal places).
tell whether each point is on the graph of f(x)=|x|.If it is, give the coordinates of another point with the same y value.
1.(11,11)
2.(-2.3,-2.3)
3.(0,1)
4.(15,-15)
5.(-8,8)
6.(1,0)
The coordinates of that other point are: (5,5) . The x-coordinate gives us the distance of a point from the vertical axis, that is, the y-axis.
What is meant by coordinates?The x-coordinate gives us the distance of a point from the vertical axis, that is, the y-axis. Another name for the x-coordinate is abscissa. The y-coordinate indicates how far a point is from the x-axis, or the horizontal axis. The y-coordinate is also called the ordinate.
Notice that |x| means the absolute value of x. So, the function:
f(x) = IxI
takes x to the number with the same magnitude, but with a positive sign.
Thus,
f(-5) = I - 5I = 5
Therefore, the point (-5,5) is on the graph of f(x).
Now, we need to find another point with a y-value of 5.
Observe the graph of f(x):
Notice that another point with a y-value equal to 5 is (5, 5) because
f(5) = I5I = 5
Hence, the coordinates of that other point are: (5,5).
The complete question is : Tell whether the point (-5,5) is on the graph of f(x) = |x|. If it is, give the coordinates of another point with the same y-value.

Professor Walter precisa pintar uma quadra, que tem o formato retangular, cujo comprimento é de 45 m por 38 m. Para isso ele vai comprar baldes de tinta em uma loja de construção. Sabendo que com cada balde de tinta ele conseguirá pintar 72 m² de piso, quantos baldes de tinta ele precisará comprar
Answer:
24 buckets
Step-by-step explanation:
Given that :
Dimension of rectangular block = 45 m by 38 m
A bucket of paint will cover 72m² of floor
Total area of floor : Length * Width
Total Area = (45m * 38m) = 1710 m²
Buckets of paint required :
Total area / Area per bucket
= 1710m² / 72m²
= 23.75 buckets
= 24 buckets

What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Table is shown in figure.
Two points on the table are (3, 0) and (4, 1).
Now,
Since, The equation of function passes through the points,
(3, 0) and (4, 1).
So, We need to find the slope of the function.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (1 - 0) / (4 - 3)
m = 1
Thus, The equation of function with slope 1 is,
⇒ y - 0 = 1 (x - 3)
⇒ y = x - 3
⇒ y = x - 3
Thus, The equation of function notation for the relation will be,
⇒ y = x - 3

Elena deposits $1,500 in a savings account that earns 3.0% simple interest per year. If no deposits or withdrawals are made during the year, how much money will be in her account after one year?
Answer:
FV= $1,545
Step-by-step explanation:
Giving the following information:
Elena deposits $1,500 in a savings account that earns 3.0% simple interest per year.
To calculate the nominal value of the account after one year, we need to use the following formula:
FV= (P*r*t) + P
FV= future value
P= principal
r= interest rate
t= 1
FV= (1,500*0.03*1) + 1,500
FV= $1,545
