Answer:
f(3) = 1
Step-by-step explanation:
To find f(3), plug in 3 as x and simplify the expression:
f(x) = 2x - 5
f(3) = 2(3) - 5
f(3) = 6 - 5
f(3) = 1
So, f(3) = 1

Step-by-step explanation:
Wally is rebuilding his fence. Each section of the fence will have 12 vertical boards that are each eight inches wide. He’s going to attach them to two horizontal pieces of wood and add a diagonal piece to brace the fence section. The horizontal pieces will be five feet apart.
1.About how long should the diagonal piece of wood be?
2. If Wally plans on using 30 sections of fence, about how many feet of wood will he need for the horizontal and diagonal pieces?
Answer:
Part A)
Each diagonal is about 9.43 feet.
Part B)
In total, Wally needs about 736.02 feet of wood.
Step-by-step explanation:
Part A)
Since each vertical board has a width of 8 inches, for one section with 12 vertical boards, the total width will be 8(12) = 96 inches.
96 inches is the same as 96/12 = 8 feet.
We are also given that the horizontal pieces will be 5 feet apart.
To find the diagonal, we can use the Pythagorean Theorem. The 8 is the base and 5 is the height. Therefore:
[tex]\displaystyle d^2=8^2+5^2[/tex]
Compute:
[tex]d^2=89[/tex]
Taking the square root, we acquire:
[tex]\displaystyle d=\sqrt{89}\approx9.43 \text{ feet}[/tex]
So, each diagonal is about 9.43 feet.
Part B)
For each section, we have two horizontal pieces (each 8 feet) and one diagonal piece (each √89 feet).
Therefore, for one section, we will need a total of:
[tex]\displaystyle L=8+8+\sqrt{89}=16+\sqrt{89}[/tex]
Then for 30 sections, we will need:
[tex]T=30(16+\sqrt{89})[/tex]
Approximate:
[tex]T\approx 763. 02[/tex]
Wally will need about 736.02 feet of wood in total.

5. Vernon drew an 8 in, wide by 5 in. tall picture that will be turned into a
48 ft wide billboard. How tall will the billboard be?
ACTICE ORIEM SOLVING
Answer:
The billboard should be 30 feet tall
Step-by-step explanation:
Height of the picture = 5 inches
Width of the picture = 8 inches
But the billboard has a width of 48 feet = 12 x 48
= 576 inches
To know how tall the billboard is, we have to determine the scale factor required.
scale = [tex]\frac{width of billboard}{width of picture}[/tex]
scale = [tex]\frac{576}{8}[/tex]
= 72
scale = 72
The height of the billboard = scale x 5 inches
= 72 x 5 inches
= 360 inches
Also,
The height of the billboard = [tex]\frac{360}{12}[/tex]
= 30 feet
Therefore, the billboard would be 30 feet tall.

D. t(x) = 4x - 1
Step-by-step explanation:
The sequence shows the first four terms. As such, the x coordinates of the graph will be 1, 2, 3, and 4. The y coordinates will be 3, 7, 11, and 15 respectively.
Graphing that, the 4 points all lie on the line 4x - 1, so D is the answer.
The graph I made for this is below.
Horatio has 230 dollars to be used only on his car. He wishes to save 160 of this money and spend $24.95 on an oil change. Horatio knows that gas costs $3.81 per gallon. Which of the following shows how many gallons of gas (g) he could buy? 3 needed.
A. g ≤ 11.82
B. g ≤ 60.37
C. 3.81 ≤ 45.05
D. 3.81 ≤ 230 + 160 + 24.95
E. 160 + 24.95 + 3.81 ≤ 230
F. 184.95 + 3.81g ≤ 45.05
I'd be greatly thankful if you told me the answers!
Answer:

In the diagram below, the angle of depression from the top of the lighthouse to a speed boat is 27 degrees. The base of the lighthouse is 33 ft away from the boat. Determine the height of the lighthouse, to the nearest tenth of a foot.
Answer:
=
412
feet
Step-by-step explanation:
The angle of depression is always measured from the horizontal.
A triangle is formed by the lighthouse, the ground and the boat. The angle of depression is not in the triangle, but it is equal to the angle of elevation at the boat. (Alternate angles on parallel lines)
The angle at the top of the lighthouse, inside the triangle is:
90°−27°
=63°
The distance to the boat is the side opposite the angle of
63°
while the height of the lighthouse is the adjacent side.
opposite
adjacent
=tan 63°
distance
210=tan 63°
distance=210×tan 63°=412 feet
