Answer:
71
Step-by-step explanation:
Recall the trig ratios
Sine = Opposite over Hypotenuse
Cosine = Adjacent over Hypotenuse
Tangent = Opposite over Adjacent
We are given ∠T's opposite side length and the adjacent side length.
When dealing with opposite and adjacent we use trig ratio Tangent.
( remember tan = opposite over adjacent )
[tex]tan(x)=\frac{52}{18}[/tex]
* multiply each side by the inverse of tan ( [tex]tan^-^1[/tex] )
[tex](tan)^-^1tan(x)=x\\(tan)^-^1*\frac{52}{18} =70.906508\\x = 70.906508[/tex]
* round to the nearest degree *
We get that x = 71

[tex] \frac{ba}{ac} = \frac{h}{rt} [/tex]
solve for h
Answer:
Step-by-step explanation:
assuming that the triangles are similar, which I can't by what is shown in the picture, but I'm guessing that there are more instructions off screen , that say they are.
' = feet
" = inches
h / 20' = 4'-2" / 3'-4"
just use inches for this, it's easier
h / 240" = 50" / 40"
h = 240 ( 50 / 40 )
h = 300"
h = 25'

Answer:
(-1, 2/3).
Step-by-step explanation:
Taking the derivative of f, we get f' = x^2 - 1 = 0. Thus, x = -1 and x = +1.
At the relative max, y = (1/3)(-1)^3 - (-1) = -1/3 + 1 = 2/3.
The relative maximum is at (-1, 2/3).

Finding a final amount in a word problem on exponential growth or decay
A principal of $3300 is invested at 8% interest, compounded annually. How much will the investment be worth after 9 years?
Use the calculator provided and round your answer to the nearest dollar.
Step-by-step explanation:
Use the formula for compound interest
f/p: f =p(1+i)^n
p = 3300
i =8% = 0.08
n = 9 years
A = p(1+r)^t
A = 3300(1+0.08)⁹
A = 3300× 1.99
A= 6596.71 dollar ~ 6597 dollar.

Based on the data, select the most reasonable prediction about the height of second-grade students.
O A. The typical second-grade student is less than 45 inches tall.
B. The typical second-grade student is about 45 inches tall.
C. The typical second-grade student is more than 50 inches tall.
D. The typical second-grade student is about 48 inches tall.
Answer:
Answer = D
Step-by-step explanation:
If you add all of the heights up you get 480. divide that by ten (because there were 10 students whose height was taken) then you get 48. therefore, the typical second-grade student is about 48 inches tall.

What is mean?'Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.'
According to the given problem,
Given data = { 44, 45, 47, 49, 48, 48, 49, 50, 48, 52 }
Sum of the given data = 44 + 45 + 47 + 49 + 48 + 48 + 49 + 50 + 48 + 52
= 480
Average of the given heights = [tex]\frac{480}{10}[/tex]
= 48
Hence, we can conclude, The typical second-grade student is about 48 inches tall since the average of the given data is 48.

Lemon plant is cycle route on a map each unit represents 1 km. What is the total length in kilometers of the route
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the map or the scale length of the plants are not given.
To solve this, I will assume that:
[tex]Scale\ Distance = x[/tex]
[tex]Scale\ Ratio = 1\ unit : 1\ km[/tex]
Required
The total length
To get the total length (actual length), multiply the scale ratio by the scale distance;
[tex]Actual = Scale\ Distance * Scale\ Ratio[/tex]
So, we have:
[tex]Actual = x * 1km[/tex]
[tex]Actual = x\ km[/tex]
Assume that:
[tex]x = 5[/tex]
The total length will be:
[tex]Actual = 5km[/tex]
A rectangular field 50 metres wide and x metres long requires 260 meters wire for fencing . Find the length of the field.
Answer:
80 meters
Step-by-step explanation:
Length of rectangular field = x
Width of rectangular field = 50
Meters of Fencing required = perimeter of rectangle = 260 m
Perimeter of a rectangle = 2(length + width)
260 = 2(x + 50)
260 = 2x + 100
260 - 100 = 2x
160 = 2x
x = 160 / 2
x = 80 meters
