Two men, 400 feet apart, observe a balloon between them; it is in the same vertical plane as they are. The respective angles of elevation of the balloon are observed by the men to be 75°20' and 49°30'. Find x rounded to the nearest whole number.
Answers
Note that
75° 20' = 75.333°
49° 30' = 49.5°
From the figure shown below, obtain by definition,
a = x cot 49.5° = 0.8541x
b = x cot 75.333° = 0.2617x
Because a + b = 400 ft, therefore
0.8541x + 0.2617x = 400
1.1158x = 400
x = 358.49 ft
Answer: 358 ft (nearest whole number)

How does changing the function from f(x) = −5 cos 2x to g(x) = −5 cos 2x − 3 affect the range of the function?
Answers
Answer:
[-8,2]
Step-by-step explanation:
We are given that the function f(x) is transformed to the function g(x), where,
[tex]f(x) =-5 \cos 2x[/tex] and [tex]g(x) =-5 \cos 2x-3[/tex].
Since, the range of [tex]\cos x[/tex] is [-1,1].
Thus, the range of [tex]a\cos bx[/tex] is {-a,a].
So, the range of [tex]f(x) =-5 \cos 2x[/tex] is [-5,5].
As, we are translating the function f(x) 3 units downward to get g(x).
The graph of the function is shifted 3 units down.
So, the range of g(x) will be [-5-3,5-3] = [-8,2].
Hence, the range of [tex]g(x) =-5 \cos 2x-3[/tex] is [-8,2].

Answers
if 2x = 4, then x = 2
A conditional statement that correctly describes each Venn diagram include the following;
I. If m∠A = 40, then it represent acute angles.
II. If 2x = 4, then x is equal to 2.
What is a conditional statement?In Mathematics, a conditional statement is a type of statement that can be written to have both a hypothesis and conclusion. This ultimately implies that, a conditional statement typically has the form "if P then Q."
Where:
P and Q represent sentences or statements.
Part I.
Based on the Venn diagram shown in the image above, we can logically deduce the following conditional statement;
"If m∠A = 40, then it represent acute angles."
All acute angles are less than 90 degrees.
Part I.
Based on the Venn diagram shown in the image above, a conditional statement that correctly describes it can be written as follows;
"If 2x = 4, then x is equal to 2."
Proof:
2x = 4
x = 4/2
x = 2

Answers
Your function f(x) should be 5^x, instead of 5x
Answer should be g(x) = 5^x - 10, since it shifts f(x) downward by 10 units
The equation of the function is , g(x) = 5x -10 , Option B is the right answer.
What is a Function ?A function is a mathematical representation of an independent variable and a dependent variable.
The given function is
f(x) = 5x
As the y intercept is shifting from (0 ,1) to (0,-9)
therefore the function is translating 10 points down
therefore the equation of the function is

Two points in the xy plane have cartesian coordinates (2.00, 24.00) m and (23.00, 3.00) m. determine (a) the distance between these points and (b) their polar coordinates
Answers
The distance between the two points is approximately 29.70 m. The polar coordinates of the points are approximately (24.20 m, 1.46 radians).
Explanation:To find the distance between two points in the Cartesian coordinate plane, we can use the distance formula.
The distance between the points (2.00, 24.00) m and (23.00, 3.00) m is:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Plugging in the values, we get:
d = sqrt((23.00 - 2.00)^2 + (3.00 - 24.00)^2)
d = sqrt(441 + 441)
d = sqrt(882)
d ≈ 29.70 m
The polar coordinates of a point (x, y) can be found using the formulas:
r = sqrt(x^2 + y^2)
p = atan2(y, x)
Plugging in the values, we get:
r = sqrt(2.00^2 + 24.00^2)
p = atan2(24.00, 2.00)
r ≈ 24.20 m
p ≈ 1.46 radians

The width of a rectangle is one half it's length. The perimeter of the rectangle is 54 cm. What are the width and length of the rectangle?
Answers
to find the perimeter, it's the width+width+length+length so:
1/2x+1/2x+x+x=54
3x=54
x=18
the length is 18 cm and the width is 9 cm
Let width of the rectangle = x/2 (or 1/2 of x)
Remember that Area = 2L + 2W, so . . .
2x + 2(x/2) = 54
2x + (2/2)x = 54
2x + x = 54
3x = 54 --> x = 54/3 --> x = 18
So the length of the rectangle is 18 cm and the width is 18/2 = 9 cm.

Answers
Answer:

Step-by-step explanation:
The volume of a pyramid with a base area of 15 square inches and a height of 7 inches is 35 cubic inches.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Suppose the base of the pyramid has length = L units and width = W units, slant height = K units, and the height of the pyramid is of H units.
Then the volume of the pyramid will be
V = (L × B × H) / 3
V = (Base area x H) / 3
The volume of a pyramid varies jointly with the base area of the pyramid and its height.
The volume of one pyramid is 24 cubic inches when its base area is 24 square inches and its height is 3 inches.
Then the volume of a pyramid with a base area of 15 square inches and a height of 7 inches will be
V = (15 x 7) / 3
V = 35 cubic inches
Hence, the volume of a pyramid with a base area of 15 square inches and a height of 7 inches is 35 cubic inches.

A rectangle is graphed on the coordinate grid.
Which represents the equation of the side that is parallel to side s?
Answers
So, the line parallel to s is q, which has these two points: (3,6) and (6,3)
There are different ways to get the line. For instance, this one:
y = a*x+b,
a = slope = difference_y/difference_x = (3-6)/(6-3) = -1,
y = -x + b,
Now use any point, say (3,6) to get b:
6 = -3+b-> b = 9,
line is y = -x + 9,
It checks out in the other point: (6,3) --> 3 = -6+9 = 3. Good.
Other method could be:
y-y2 = a*(x-x2), where (x2,y2) is one of the two points and a is the slope as defined before.
Hope it helps!
The side that is parallel to side s is side q. The equation of side q is: y = -x + 9.
What is the Equation of a Line?We can represent the equation of a line as, y = mx + b, where m is the slope of the line and b is the y-intercept.
The side that is parallel to side s is q.
Slope (m) of q = change in y / change in x = (6 - 3) / (3 - 6) = 3/-3 = -1.
Substitute m = -1 and (3, 6) = (a, b) into y - b = m(x - a):
y - 6 = -1(x - 3)
y - 6 = -x + 3
y = -x + 3 + 6
y = -x + 9
