Complete question :
dion places a ladder against The side of his house as shown in the diagram below. Dion’s water is 26 feet long, and he places the ladder at a 70° angle with the ground, How high does the ladder reach up the side of the building?.
Answer:
24.43 feets
Step-by-step explanation:
Using trigonometry :
Sinθ = opposite / hypotenus
Opposite = height, h
Hypotenus = 26
Sin 70° = h / 26
0.9396926 * 26 = h
height, h = 24.43 feets
The sine rule is the ratio of the height and hypotenuse. Then the height of the wall is 24.43 ft.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function. The Pythagoras is the sum of the square of two sides is equal to the square of the longest side.
Dion places a ladder against the side of his house as shown in the diagram below.
Dion’s water is 26 feet long, and he places the ladder at a 70° angle with the ground, represented by zero.
We have
Hypotenuse (H) = 26 ft
Let h be the height of the la
Then the height of the wall will be given by the sine rule.
[tex]\rm h = H sin \ \theta \\\\h = 26 * sin \ 70^o\\\\h = 24.43 \ ft[/tex]
The height of the wall is 24.43 ft.

Tell whether the triangle with each set of side lengths is a right triangle.
(See picture)
Answer:
Right Triangles:
(5.1, 6.8, 8.5) and (12.5, 30, 32.5)
Not Right Triangles:
(2.2, 4.5, 6.7) and (4.7, 8.6, 10.7)
Step-by-step explanation:
I solved by using the pythagorean theorem (a^2+b^2=c^2)
Plug the side lengths in, the largest side length is always c. If the equation comes out true, it is a right triangle.

I need help find the volume of the composite solid use 3.14 for pi
Answer:
[tex]222.312\:\mathrm{in^3}[/tex]
Step-by-step explanation:
The composite solid consists of a cylinder and a cone. Therefore, its total volume will be the sum of the volumes of the cylinder and cone:
Volume of the cone: [tex]\frac{1}{3}\cdot 2^2\cdot 3.14\cdot 8.1 =33.912[/tex]
Volume of the cylinder: [tex]2^2\cdot 3.14 \cdot 15=188.4[/tex]
Thus, the total volume of the solid is:
[tex]33.912+188.4=\boxed{222.312\:\mathrm{in^3}}[/tex]

What are the values for q that will make the equation true |4q+12|=4
Hi there! Solving the absolute value equation is like solving a quadratic equation.
[tex] \large{ |x| = a \longrightarrow x = \pm a}[/tex]
[tex] \large{ |x| = \begin{cases} x \: \: \: (x \geqslant 0) \\ - x \: \: \: (x < 0) \end{cases}}[/tex]
From the absolute equation:
[tex] \large{ |4q + 12| = 4}[/tex]
Cancel the absolute symbol and write plus-minus of 4.
[tex] \large{4q + 12 = \pm 4}[/tex]
Solve the equation for q-term.
[tex] \large{4q = \begin{cases} 4 - 12 \\ - 4 - 12 \end{cases}} \\ \large{4q = \begin{cases} - 8 \\ - 16 \end{cases}} \\ \large{q = \begin{cases} - \frac{8}{4} \\ - \frac{16}{4} \end{cases}} \\ \large{q = \begin{cases} - 2 \\ - 4 \end{cases}}[/tex]
Hence, the value of q are -2,-4

Which expression defines the arithmetic series 1 + 5 + 9 + ... for seven terms?
Σ(27-1)
Σ(3n-4)
Σ(4n-3)
Σ(n-1)
Answer:
[tex]\sum\limits^7_{n=1}(4n - 3)[/tex]
Step-by-step explanation:
Given
[tex]1 + 5 + 9 + .....[/tex]
Required
Write a definition
First, we derive a formula for the series using:
[tex]T_n = a + (n - 1)d[/tex]
From the attached data;
[tex]a = 1[/tex]
[tex]d = 5 - 1 = 4[/tex]
So:
[tex]T_n = a + (n - 1)d[/tex]
[tex]T_n = 1 + (n - 1) * 4[/tex]
[tex]T_n = 1 + 4n - 4[/tex]
Collect like terms
[tex]T_n = 4n - 4+1[/tex]
[tex]T_n = 4n -3[/tex]
So, the definition for first 7 terms is:
[tex]\sum\limits^7_{n=1}(4n - 3)[/tex]

in an inverse variation, x=2 when y=-4. what is the value of y when x=16
Answer:
y = -1/2
Step-by-step explanation:
Use the inverse variation equation, y = [tex]\frac{k}{x}[/tex]
Plug in 2 as x and -4 as y, then solve for k:
y = [tex]\frac{k}{x}[/tex]
-4 = [tex]\frac{k}{2}[/tex]
-8 = k
So, the equation is y = [tex]\frac{-8}{x}[/tex]
Plug in 16 as x and solve for y:
y = [tex]\frac{-8}{x}[/tex]
y = [tex]\frac{-8}{16}[/tex]
y = -1/2
So, when x = 16, y = -1/2
