Step-by-step explanation:
Simon's dog jumped into
a stream at a 68° angle from the corner of a bridge. simon crossed the bridge and walked downstream to meet the dog
part a: how long is the bridge, in feet?
part b: how many feet did the dog swim?
The length of the bridge and the length the dog swam are 12.12 feet and 32.36 feet respectively
The problem forms a right angle triangle.
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees. The sides and angle can be found using trigonometric ratios.
Therefore, the length of the bridge and the length the dog swam can be calculated as follows:
tan 68° = opposite / adjacent
tan 68° = 30 / x
cross multiply
x = 30 / tan 68
x = 12.12 ft
length of the bridge = 12.12 ft
The length the dog swim is as follows:
sin 68°= opposite / hypotenuse
sin 68° = 30 / h
h = 30 / sin 68
h = 32.3561767942
The distance the dog swimmed = 32.36 ft

What is the measure of angle x?
Enter your answer in the box.
x = ?°
Answer:
x = 43°
Step-by-step explanation:
The three angles to the right of the diagonal line add up to give the angle measure of the line:
x +90° +47° = 180°
x = 43° . . . . . . . . . . . . . subtract 137° from both sides

Answer:
Step-by-step explanation:
x = 5.4178
10000x = 54178.178
10x = 54.178 Subtract: that gets rid of the repeating decimal.
9990x = 54124 Divide by 9990 on both sides
9990x/9990 = 54124/9990 The Greatest common divisor of these two is 2
x = 27062/ 4995
p/q = 27062 / 4995

Answer:
k = 52
Step-by-step explanation:
- 8 = [tex]\frac{k-4}{-6}[/tex] ( multiply both sides by - 6 to clear the fraction )
48 = k - 4 ( add 4 to both sides )
52 = k
Answer: k=52
Step-by-step explanation:
-8= k-4/-6
multiply by -6
48=k-4
add 4 to both sides
k=52 :)
Find the perimeter and area of a regular hexagon with side lengths of 8 and an apothem of 9.
The perimeter and area of a regular hexagon with side length of 8 and apothem of 9 are 48 units and 216 units² respectively.
What is a regular hexagon?A regular hexagon is a polygon with 6 sides and the angles are congruent.
The perimeter of the hexagon is the sum of the whole sides. Therefore,
side length = 8 units
apothem = 9 units
perimeter = 8 × 6 = 48 cm
The area of the hexagon can be calculated as follows:
area = 1 / 2 pa
where
p =perimeter
a = apothem
Therefore,
area = 1 / 2 × 48 × 9
area = 432 / 2
area = 216 units²

If you have
[tex]3^{n-1} *\frac{n(n+1)}{2} = 20412[/tex]
whats the process for solving n?
Answer:
Step-by-step explanation:
3^(n-1) * (n(n+1)/2 = 20412
The n(n +1)/2 is a factorial which is defined for integers so we are looking for a whole number solution.
We could draw a graph manually or using software and get the solution where the graph cuts the x axis.
Also we could find the prime factors of 20412:
20412 = 2^2 * 3^6 * 7
and try substituting 2, 3 and 7 into the equation
Using this method we see that one solution is n = 7.
I could have tried n = 7 first because 3^n-1 = 3^6!!

47 The figure below shows Andrew's plan for a deck. 24 ft 22 ft 12 ft 33 ft [not drawn to scale] Find the area, in square feet, of the deck.
Show your work,
Answer:
681ft^2
Step-by-step explanation:
Start by finding the area of the whole thing with the missing triangle:
33 x 22 = 726
Then find the area of the triangle. You can do this by first finding out the side lengths of the triangle:
33 - 24 = 9 and 22 - 12 = 10
Then multiply both sides and divide by two because it is a triangle:
10 x 9 = 90 90/2 = 45
Then subtract the area of the triangle from the rectangle:
726 - 45 = 681

3(x-5)^2-17=-5
Answer:
x = 3 , x = 7
Step-by-step explanation:
3(x - 5)² - 17 = - 5 ( add 17 to both sides )
3(x - 5)² = 12 ( divide both sides by 3 )
(x - 5)² = 4 ( take square root of both sides )
x - 5 = ± [tex]\sqrt{4}[/tex] = ± 2 ( add 5 to both sides )
x = 5 ± 2
then
x = 5 - 2 = 3
x = 5 + 2 = 7
fill in the table using this function rule. y= 3x + 4

y- blank
Answer:
y: 13, 22, 25, 28
ordered pairs: (3, 13) (6, 22) (7, 25) (8, 28)
Step-by-step explanation:
Given:
function: y = 3x + 4values of x: -3, 6, 7, 8To find the y-values, substitute the x-values into the function and solve.
when x = 3
y = 3(3) + 4
= 9 + 4
= 13
when x = 6
y = 3(6) + 4
= 18 + 4
= 22
when x = 7
y = 3(7) + 4
= 21 + 4
= 25
when x = 8
y = 3(8) + 4
= 24 + 4
= 28
Therefore, the ordered pairs are; (3, 13) (6, 22) (7, 25) (8, 28)

The balloon rises vertically so that the distance between the balloon and Student A is 90 feet. How
many feet did the balloon rise? Express your answer to the nearest foot.
Using the Pythagorean Theorem, it is found that the balloon rises 67.08 feet.
What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
Researching this problem on the internet, it is found that the situation is modeled by a right triangle, in which the horizontal distance between the balloon and the student is of 60 ft, the vertical distance is of h, while the hypotenuse is of 90 ft, hence:
[tex]60^2 + h^2 = 90^2[/tex]
[tex]h = \sqrt{90^2 - 60^2}[/tex]
[tex]h = 67.08[/tex]
The balloon rises 67.08 feet.
