Answer:
a) θ = 14°
b) θ = 62°, A = 28°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relation ...
Tan = Opposite/Adjacent
This is the useful relation in each case.
__
a) tan(θ) = 43/172
θ = arctan(43/172) ≈ 14°
__
b) tan(θ) = 32/17
θ = arctan(32/17) ≈ 62°
A = complement of θ = 90° -62° = 28°

find out the total volume of cube _Edge Length =6 inches
Answers
Given:
The edge length of a cube = 6 inches
To find:
The volume of the cube.
Solution:
We know that, the volume of a cube is
[tex]V=a^3[/tex] ...(i)
Where, a is the edge length.
Substituting a=6 in (i), we get
[tex]V=(6)^3[/tex]
[tex]V=216[/tex]
Therefore, the total volume of the cube is 216 cubic inches.

Answers
Answer:
224
Step-by-step explanation:
For the square 6*6 = 36
and for the triangles 8*6*2 = 96
96*2 for 2 triangles is 96*2 = 192
192+36 = 224
The formula for the square is length x width or height x base
The formula for EACH triangle is base x height x 2 or divided by 1/2
I multiplied 96 times 2 because there were 2 triangles

Calculate the velocity of a body of mass 100g having kinetic energy of 100J.
Answers
Answer:
the velocity is 1.41421 m/s
Step-by-step explanation:
The computation of the velocity is shown below:
As we know that
Kinetic energy = 1 ÷ 2 × m × v^2
100 J = 1 ÷ 2 × 100 g × v^2
100 J = 50g × v^2
After solving it v is 1.41421 m/s
hence, the velocity is 1.41421 m/s
If Profit Tk.100000 from reduced tk. 190000. What will be the profit reduce rate
Answers
Answer:
the profit reduced rate is -0.4737
Step-by-step explanation:
The computation of the profit reduced rate is shown below:
= (100,000 - 190,000)÷ (190,000)
= -90,000 ÷ 190,000
= -0.4737
hence, the profit reduced rate is -0.4737
We simply takes the difference and then divided it by 190,000
what is −3(2a)+−4(−6b)+5(3c) written on standard form. pls help asap
Answers
Answer:
-6a+24b+15c
Step-by-step explanation:
The given expression is :
−3(2a)+−4(−6b)+5(3c)
We need to write it in the standard form.
We know that,
-3(2) = -6, -4(-6) = 24 and 5(3) = 15
−3(2a)+−4(−6b)+5(3c) = -6a+24b+15c
Hence, the required answer is equal to "-6a+24b+15c".

im stuck on matching functions to graph with function notation. i dont know what to do. Someone please help.
Answers
Answer:
Since the function notation lets us write f(x) instead of y, the graph of a function f is the set of all points (x, f(x)), where x is in the domain of the function. example Graph f(x) = 5x - 1 and find the value of f(3) by using the graph. The y-intercept is -1 and the slope is 5. When x = 3, y equals 14.
