Answer:

f(-5) = 22

Step-by-step explanation:

f(x) =-3x+7

ivolga24 [154]

Answer: x=3.16m

Step-by-step explanation:

The condition for destructive interference is given by:

∆r = r1 - r2 = (m + 0.5)lamda

Where

Lamda = speed/frequency

= 343/260 = 1.32m

r1. = x

r2 = 2.50m

Then;

X - 2.5 = (m + 0.5)v/f

X - 2.5 = (m + 0.5)1.32

For m = 0 i.e at maximum destructive interference

x = 3.16m

Find the are of each solid figure
Tju [1.3M]
Perimeter of the base = 8 + 5 + 5 = 18 ft

Height = 7 ft

Base area = 1/2 x 8 x 3 = 12 ft²

Surface area = (18)(7) + 2(12) = 150 ft²

--------------------------------------------------
Answer: 150 ft²
--------------------------------------------------

The above answer is according to the worksheet but I will present it in another way for you to understand better.

The figure has 5 sides

-------------------------
Bottom Triangle
-------------------------
Area = 1/2 x base x height
Area = 1/2 x 8 x 3
Area = 12 ft²

-------------------------
Top Triangle
-------------------------
Top Triangle = Bottom Triangle
Top Triangle = 12 ft²

-------------------------
3 Rectangles on the sides
-------------------------
Area of 1st Rectangle = Length x Width
Area of 1st Rectangle = 7 x 5 = 35 ft²
Area of 2nd Rectangle = 7 x 5 = 35 ft²
Area of 3rd Rectangle = 8 x 7 = 56 ft²
Total area of the rectangles = 35 + 35 + 56 = 126 ft²

-------------------------
Total Surface Area
-------------------------
126 + 12 + 12 = 150 ft²

<em>(*Area of the 3 rectangles + top triangle + bottom triangle)
</em>
-------------------------
Answer: 150 ft²
-------------------------
