Joshua has a ladder that is 15 ft long. He wants to lean the ladder against a vertical wall so that the top of the ladder is 14.2 ft above the ground. For safety reasons, he wants the angle the ladder makes with the ground to be no greater than 78°.
Will the ladder be safe at this height? Show your work and label the diagram to support your answer.
Yes the ladder be safe at this height.
What is angle of elevation?The angle formed by the line of sight and the horizontal plane for an object above the horizontal.
Given:
ladder = 15 ft long.
top of the ladder is 14.2 ft above the ground.
Using trigonometry,
sin x = 14.2/15

The final balance is $4,926.8.The total compound interest is $3,926.8.
The value of r is 2 %.
What is simple & compound interest?Simple Interest can be defined as the sum paid back for using the borrowed money, over a fixed period of time. Compound Interest can be defined as when the sum principal amount exceeds the due date for payment along with the rate of interest, for a period of time. Formula. S.I. = (P × T × R) ⁄ 100.
Given:
Principal(P)= $4540
Rate = ?

The perimeter of the composite figure shown in the figure is equal to 5 · [2 + √2 · (1 + √5)] units (approx. 32.882 units) and the total area is 33.5 square units.
How to determine the perimeter and the area of a composite figure
In this case we have a composite figure formed by six triangles and two rectangles. The perimeter is the sum of the side lengths and the area is the sum of the areas of the triangles and rectangles. The perimeter of the entire figure is described below:
p = AB + BC + CD + DE + EF + FG + GA
p = 5√2 + √10 + √10 + 5 + √10 + 5 + 2√10
p = 10 + 5√2 + 5√10
p = 10 + 5 · (√2 + √10)
p = 10 + 5√2 · (1 + √5)
p = 5 · [2 + √2 · (1 + √5)]
And the area of the composite figure is determined by the following expression:
A = 0.5 · (3) · (1) + (3) · (4) + 0.5 · (3) · (1) + 0.5 · (3) · (1) + 0.5 · (3) · (1) + (3) · (2) + 0.5 · (7) · (1) + 0.5 · (6) · (2)
A = 2 · (3) · (1) + (3) · (4) + (3) · (2) + 0.5 · (7) · (1) + 0.5 · (6) · (2)
A = 33.5

Solve the systems of equations below using the method indicated in each part of the table. Be sure to show ALL your work for each method in order to get full points! (15 points)
The solutions to the systems of equations are:
1. (2, 3) (see attachment below). [one solution]
2. no solution
3. (3, 13) [one solution]
Solution to a System of Equations?The solution to a system of equations is the x-value and y-value that will make both equations true. It can be found either using a graph, by elimination method, or substitution method as explained below.
1. Using graph to solve y = 2x - 1 and y = 4x - 5:
The solution is the point where both lines intersect which is: (2, 3) (see attachment below). [one solution]
2. Solving using substitution method:
x = -5y + 4 ---> eqn. 1
3x + 15y = -1 ---> eqn. 2
Substitute x = -5y + 4 into eqn. 2
3(-5y + 4) + 15y = -1
-15y + 12 + 15y = -1
-15y + 15y = -1 - 12
0 = -13 (this shows that there is no solution)
3. Using elimination method:
14x = 2y + 16 ---> eqn. 1
5x = y + 2 ---> eqn. 2
1(14x = 2y + 16)
2(5x = y + 2)
14x = 2y + 16 ----> eqn. 3
10x = 2y + 4 -----> eqn. 4
Subtract
4x = 12
x = 12/4
x = 3
Substitute x = 3 into eqn. 2
5(3) = y + 2
15 = y + 2
15 - 2 = y
13 = y
y = 13
The solution is: (3, 13).

The simplified expression of (7 + 9i)(8 - 10i) is 146 + 2i
How to simplify the expression?The expression is given as:
(7 + 9i)(8 - 10i)
Expand the bracket
7 * 8 + 9i * 8 -7 * 10i - 9i * 10i
Evaluate the products

Evaluate the difference
56 + 2i - 90(i²)
In complex numbers;
i² = -1
So, we have:
56 + 2i - 90(-1)
Evaluate

PLease helpppp!! only have 2 minutesd
Answer:
181.24
Step-by-step explanation:
The total surface area of the Trapezoidal Prism to be covered is: 181.24 cm².
What is the Surface Area of a Trapezoidal Prism?Surface Area = 2(area of trapezoid) + area of the 4 rectangular faces.
Area of Rectangle 1 = length × width = 9 × 4 = 36 cm²
Area of Rectangle 2 = length × width = 9 × 5 1/4 = 47.25 cm²
Area of Rectangle 3 = length × width = 9 × 4 1/5 = 37.8 cm²
Area of Rectangle 2 = length × width = 9 × 6 1/2 = 58.5 cm²
Area of the two trapezoids = 2[1/2(a + b)h] = 2[1/2(6½ + 5¼)4] = 47 cm²
Surface area = 36 + 47.25 + 37.8 + 58.5 + 47 = 226.55 cm²
Total surface that will be covered = 4/5(226.55) = 181.24 cm²
