Answer: Width: 3.5 Length:10
Step-by-step explanation:
width=x
length=2x+3
area=35
x(2x+3)=35
2x^2+3x=35
2x^2+3x-35=0
(2x-7)(x+5)=0
x obviously cannot be negative ,so x=3.5
40 according to google calculator
Answer:
- Amplitude is -5
- Period is 2π
- phase shift is -2π
Step-by-step explanation:
We can write a general wave function equation as:
Where:
- A is the amplitude .
- 2π/B is the period
- C is the phase shift
- D is the vertical shift
Our equation is:
Hence, comparing both equation we will conclude:
- Amplitude is -5
- Period is 2π
- phase shift is 2π
I hope it helps you!
Answer:
B. proportion
Step-by-step explanation:
A proportion is a pair of equal ratios.
Answer:
Neither
Step-by-step explanation:
Can be determined because there is enough information (Length, width, and height).
Not congruent because from the picture itself, the figures are in different sizes.
Not similar because:
The height ratio is not the same as the ratios of other dimensions.
1 : 4 is not similar to 6 : 12 and 4 : 8
