To the nearest degree, find an approximate measure of the angle of elevation to the sun when a tree whose height is 32 meters casts a shadow 35 meters long. Enter a number answer only.
Step-by-step explanation:
the angle of elevation is the angle on the ground at the end of the shadow abs aiming towards the sun.
we know one angle : the 90° between the tree and its shadow (on the ground).
so, we can calculate with Pythagoras the length of the line of sight bergen the end of the shadow and the top of the tree, which is the Hypotenuse of this right-angled triangle.
Hypotenuse² = 32² + 35² = 1024 + 1225 = 2249
Hypotenuse = sqrt(2249) = 47.42362281... m
the height of the tree is the sine of the angle of elevation multiplied by the length of the Hypotenuse (as the radius of the virtual circle).
32 = sin(angle) × sqrt(2249)
sin(angle) = 32/sqrt(2249) = 0.6747692...
angle of elevation = 42.43622979...° ≈ 42°
The dimensions of a rectangle are 2x - 5 and 3x – 4. Which expression
best represents the area of the rectangle in simplest terms?
A. -17x^2 -20
B. 6x^2 -23x +20
C. 6x^2 +20
D. 6x^2 -7x -20
Answer:
so you would rewrite them as (2x-5)(3x-4)
then multiply 2x×3x=6x^2 then -5×-4=20
so the expression is C. 6x^2+20

How to analysis the perimeter formula of a rectangle inside a parabola
a) The perimeter of a rectangle ([tex]p[/tex]) is the sum of the lengths of its four sides:
[tex]p = AB\cdot AC[/tex] (1)
If we know that [tex]AB = 2\cdot x[/tex] and [tex]AC = 9-x^{2}[/tex], then the perimeter of the rectangle is represented by the following formula:
[tex]p = 2\cdot x \cdot (9-x^{2})[/tex]
[tex]p = 18\cdot x -2\cdot x^{3}[/tex]
The perimeter function of the rectangle is [tex]p = 18\cdot x -2\cdot x^{3}[/tex]. [tex]\blacksquare[/tex]
b) The domain of the function is the set of values of [tex]x[/tex] associated to the function. After a quick inspection, we find that the domain of the perimeter function is [tex]x \in [-3, 3][/tex]. [tex]\blacksquare[/tex]

Answer:
The first option is correct: Angle 2 through 5
Step-by-step explanation:
Both angles 2 and 5 are directly vertical or opposite to each other and are the only angles that are proportionate/equal sizes.
The other three options are incorrect because angles 4 and 3 are not the same equal value and are right next to each other making them not vertically across.
angles 1 and 5 are close to being vertical but are not the same size as angle 1 is much smaller than angle 5.
angles 6 and 1 are next to each other making them not vertically to each other and angle 6 is much larger than angle 1.
the correct answer is angles 2 and 5, the first option.

If the perimeter of the rectangle is 60 feet how long are the base and height of hermans rectangle
Answer:
If the perimeter of the rectangle is 60 feet, how long are the base and height of Herman's rectangle? Show how you know.
Step-by-step explanation:
B=4x|(4.10) x+x+4x+4*=60.
The dimension of the Herman rectangle will be 24 feet by 6 feet.
What is the perimeter of the rectangle?Let W be the rectangle's width and L its length.
The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be
Perimeter of the rectangle = 2(L + W) units
If the perimeter of the rectangle is 60 feet. And we know that the ratio of length to width of Herman rectangle will be 4/1.
L = 4W
Then the equation is given as,
60 = 2 (4W + W)
30 = 5W
W = 6 feet
Then the size of the length is given a,
L = 4W
L = 4 x 6
L = 24 feet
The dimension of the Herman rectangle will be 24 feet by 6 feet.

Answer: x = 6
Step-by-step explanation:
Because we are given that the two figures are already similar, we can set up a proportional relationship to determine the value of x. Since the larger rectangle has a width of 21 and the smaller rectangle has a width of 7, those values can be used as the numerators in the proportion. Since the larger rectangle's length is x plus the additional 3 units on the smaller rectangle, x+3 and 3 can be used as the denominators in the proportion.
Next, we set up the proportion as follows:
[tex]\frac{21}{x+3} =\frac{7}{3}[/tex]
Then, you cross multiply to get the equation:
[tex]63=7x+21[/tex]
After solving down algebraically, you get the value of x to be 6.

Find the:
SLOPE =
y - Intercept=
x - Intercept=
Of the equation y=x-4
Answer:
slope = 1
y-intercept = (0 , -4)
x - intercept = (4 , 0)
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
Note that there is no number besides the x. When this happens, the slope is to be assumed as 1.
The number (and sign) that replaces the b is the y-intercept. In this case, it is (0 , -4).
The x-intercept is the point in which you intercept the y-line at 0. Plug in 0 for y, and solve for x:
0 = 1(x) - 4
0 = x - 4
0 (+4) = x - 4 (+4)
x = 4
x-intercept = (4 , 0)

Answer:
25 days
Step-by-step explanation:
If 6 men each work for 5 hours a day: 6 x 5 = 30 hours of work per day
If it takes them 50 days to build the house, then 30 x 50 = 1500 hours work in total to build the house.
If 10 men are working 6 hours a day each: 10 x 6 = 60 hours of work per day.
So 1500 ÷ 60 = 25 days
Therefore, it would take 10 men 25 days to build a house if they were each working 6 hours per day.
