Answer:
I think it’s 18
Answer:
18
Step-by-step explanation:

Answer:
6. (A, B, C) ≈ (112.4°, 29.5°, 38.0°)
7. (a, b, C) ≈ (180.5, 238.5, 145°)

We suppose you're to make use of the Law of Sines and the Law of Cosines, as applicable.
6. When 3 sides are given, the Law of Cosines can be used to find the angles. For example, angle A can be found from ...
A = arccos((b² +c² -a²)/(2bc))
A = arccos((8² +10² -15²)/(2·8·10)) = arccos(-61/160) = 112.4°
The other angles can be found by permuting the variables appropriately.
B = arccos((225 +100 -64)/(2·15·10) = arccos(261/300) ≈ 29.5°
The third angle can be found as the supplement to the other two.
C = 180° -112.411° -29.541° = 38.048° ≈ 38.0°
The angles (A, B, C) are about (112.4°, 29.5°, 38.0°).
__
7. When insufficient information is given for the Law of Cosines, the Law of Sines can be useful. It tells us side lengths are proportional to the sine of the opposite angle. With two angles, we can find the third, and with any side length, we can then find the other side lengths.
C = 180° -A -B = 145°
a = c(sin(A)/sin(C)) = 400·sin(15°)/sin(145°) ≈ 180.49
b = c(sin(B)/sin(C)) = 400·sin(20°)/sin(145°) ≈ 238.52
The measures (a, b, C) are about (180.5, 238.5, 145°).
Find Sin L=
Will mark as brainliest
Answer:
[tex]\Huge\boxed{\frac{3}{5}}[/tex]
Step-by-step explanation:
The trigonometric ratio for sine is
sin = opposite over hypotenuse
the opposite side length of L is 6 and the hypotenuse is 10
so sin L = 6 over 10
then we simplify
6/2 = 3
10/2=5
the answer would be 3/5

A frustum of height 4 is part of a larger pyramid of height 6. What is the ratio of the volume of the frustum to the volume of the pyramid?
Answer:
26 : 27Step-by-step explanation:
The volume of the pyramid with height of 6:
V = 1/3bh = 1/3b*6 = 2b,b is area of the baseThe volume of the smaller pyramid is:
V₁ = 1/3*b₁h₁We know:
h₁ = 6 - 4 = 2h₁/h = 2/6 = 1/3The base sides have same ratio as similar triangles.
b₁ = (1/3)²b= b/9The volume of smaller pyramid:
V₁ = 1/3*2*b/9 = 2b/27The difference of the volumes is the volume of the frustum:
V₂ = V - V₁V₂ = 2b - 2b/27 = 52b/27The ratio of V₂ to V is:
52b/27 ÷ 2b = 26/27OBJECTIVES QUESTIONS

18(3x+1)+3 ; x=2 evaluate the expression for the given value of the variable.
Answer:
Not sure but I think the answer is 129
Step-by-step explanation:
first, substitute the value of x in the expression like this
18(3*2+1)+3
after substituting, our work has made easier
18(6+1)+3
18(7)+3 or simply 18*7+3
126+3

9+3=8m
12=8m
m=12/8
m=3/2
The equation of the line is y=3x/2-3
How many diagonals does a
rectangle have?
A rectangle has two pairs of opposite sides that are equal in length and four right angles.
To determine the number of diagonals a rectangle has, we need to consider that a diagonal connects any two non-adjacent vertices of a shape.
In a rectangle, there are four vertices. For each vertex, we can draw a diagonal to any of the other three vertices that are not adjacent. Since there are four vertices in total, we can draw a diagonal from each of the four vertices to three other vertices, resulting in a total of 4 * 3 = 12 diagonals.
However, we must keep in mind that each diagonal is counted twice since it connects two different vertices. Therefore, we need to divide the total count of diagonals by 2, giving us the final answer.
Hence, a rectangle has 12/2 = 6 diagonals.

Which function describes the graph below?
X
f(x) = V22
g(x) = V322
Find (f .g)(x). Assume x2 0.
O A. (f.g)(x) = 8x
B. (f.g)(x) = 8VC
O c. (f.g)(x) = 32x
D. (f.g)(x) = V34x
Answer:
Step-by-step explanation:
g(x) = √(32x) = √(2⁵x) = 4√(2x)
(f∘g)(x) = f(g(x))
= f(4√(2x))
= √(2 ⋅ 4√(2x))
= √(8√(2x))
= √8∜2∜x
= ∜(2⁷x)
= ∜(128x)
which doesn’t match any of the choices. There’s an error in the question.
I believe that the functions were written incorrectly and the x should not be part of the radicands (see attachment). That makes the answer A.

d.) None of these
Answer:
D
Step-by-step explanation:
The article "an" can only be used with the word "event" so that automatically takes the choices b and c out of the way. An event is something that happens and causes the outcome, it is not the outcome, so it is not A. Thus, the answer is D

Answer:
y's go
13, 6, 5, 4, -3
Step-by-step explanation:
well so you have the equation y = 5 - x^3
you are given the x for all of them
y = 5 - (-2)^3
5 - (-8) = 13
y = 5 - 0^3
5 - 0 = 5
y = 5 - 1^3
5 - 1 = 4
y = 5 - 2^3
5 - 8 = -3
