shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero for this function. which statement is true?
Answers
Answer:
The given equation will have two roots as +5i and -5i
Step-by-step explanation:
Shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero for this function
The given equation is [tex]x^2+25 =0[/tex]
This clearly shows it will have complex roots, and since it is a quadratic equation it will have 2 complex roots
[tex]x^2 = -25 \\x = \sqrt{-25} \\x= \sqrt{-1}* \sqrt{25}\\[/tex]
[tex]x = i\sqrt{25}[/tex]
x = ± 5i
It will be false to say that -5i will be the only complex root to this equation.
The given equation will have +5i and -5i as its roots.
Lets verify
x = +5i
[tex](5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25\\-25 + 25 = 0[/tex]
x = -5i
[tex](-5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25 \\-25 + 25 \\ = 0[/tex]

You want to buy a shirt that costs $14. Identify an inequality that represents the amount of money, x (in dollars), you will have left if you buy the shirt
Answers
Complete question :
You can spend up to $35 on a shopping trip.
a. You want to buy a shirt that costs $14. Write and solve an inequality that represents the amount of money you will have left if you buy the shirt.
b. You notice that the shirt is on sale for %30 off. How does this change the inequality?
c. Do you have enough money to buy the shirt that is on sale and a pair of pants that cost $23? Explain.
Answer:
x ≤ 21
x ≤ 25.2
Yes
Step-by-step explanation:
Cost of shirt = $14
Total Amount to spend ≤ $35
After shirt purchase :
Let amount left = x
x + 14 ≤ 35
x ≤ 35 - 14
x ≤ $21
B.) discount on shirt sale = 30%
(100% - 30%) of $14 = 0.7 * $14 = $9.8
x ≤ 35 - 9.8
x ≤ 25.2
C.)
Cost of Jean = 23
25.2 > 23
Hence, there is enough money

Answer:
= − 7 /1 1 in fraction form
Step-by-step explanation:
STEP 1: Multiply by 1
1 + 1 0 + 2 5 = 1 8
+ 1 0 + 2 5 = 1 8 STEP 2: Combine like terms
+ 1 0 + 2 5 = 1 8
1 1 + 2 5 = 1 8 STEP 3: Subtract 2 5 from both sides of the equation
11x+25=18
1 1 + 2 5 − 2 5 = 1 8 − 2 5
STEP 4: Simplify by subtracting the numbers
1 1 + 2 5 − 2 5 = 1 8 − 2 5
11x+25−25=18−25 1 1 = 1 8 − 2 5 1 1 = -7
STEP 5: Divide both sides of the equation by the same term 1 1 = − 7 11x/ 11x = −7/ 1 1 (set up as a fraction) STEP 6: Cancel terms that are in both the numerator and denominator

Frequency = 8 Hz ; Period = 0.125 s
Step-by-step explanation:
The amplitude of a wave is simply regarded as the maximum displacement experienced by a vibrating both from its equlibrum position.
The Displacement marked A in th picture is tbe Amplitude of the wave
The wavelength refers to the a complete cycle moved by a wave, that is the distance from a crest to another (maximum upward Displacement) or a trough to another (maximum downward Displacement).
2.)
Given that :
Velocity (V) of wave = 20 m/s
Wavelength (λ) = 2.5 m
The frequency (f) of the wave ;
f = v /λ
f = (20 m/s) ÷ 2.5m
f = 8 Hz
The period T of the wave :
T = 1 /f
T = 1 / 8
T = 0.125 seconds
