Answer:
-8, -3, 2 ad 7
Step-by-step explanation:
This graph shown is a polynomial function. The solution is the point where the curves cuts the x axis. From the diagram we can see that the curves cuts the x axis at four points.
The points are at x1 = -8, x2 = -3, x3 = 2 and x4 = 7
Hence the real solutions to the function f(x) = 0 are -8, -3, 2 ad 7

Answers
Answer:
Discriminant = -92
the equation has no distinct real numbers
Step-by-step explanation:
Given the function f(x) = 4x^2 + 2x + 6 where;
a = 4, b = 2 and c= 6
The discriminant is expessed as D = b^2 - 4ac
Substitute;
D = 2^2 - 4(4)(6)
D = 4 - 96
D = -92
Hence the discriminant is -92.
Since the discriminant is less than zero i.e D< 0, this shows that the zeros of the equation are not real but complex numbers. Hence, the equation has no distinct real numbers
Answer:
-92 is the discriminant
0 real value 0's

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

If 65% of a number is 169 and 15% of the same number is 39, find 80% of that number.
Answers
Answer:
208
Step-by-step explanation:
169/65%=260= the original number
260 x 80% = 208
Answer:
208 is 80% of that number
Step-by-step explanation:
to find the number, take 65/100 (or 65%), and set it equal to 169/x (because x is the number that 169 is 65% of, so we need to find x)=> 65/100=169/x
Next, cross multiply to get 16900=65x
Divide both sides of the equation by 65 to get 260=x, which means that 260 is the mystery number that the question speaks of. Then, to get 80% of 260, set 80/100 equal to x/260=> 80/100=x/260
cross multiply to get 20800=100x
divide both sides by 100 to get 208
Therefore, the answer is 208

Answers
Answer:
An equation for the nth term of the arithmetic sequence.
[tex]a_n=3n-1[/tex]
Step-by-step explanation:
Given the sequence
2,5,8,11,...
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
here
a₁ = 2computing the differences of all the adjacent terms
d = 5-2 = 3, d = 8-5=3, d=11-8=3Using the nth term formula
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substituting a₁ = 2, d = 3
[tex]a_n=2+\left(n-1\right)3[/tex]
[tex]=2+3n-3[/tex]
[tex]=3n-1[/tex]
Thus, an equation for the nth term of the arithmetic sequence.

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

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]
Lydia gets kicked out of class twice in 20 minutes. How many times will she get kicked out in 6 hours?
Pop Smoke drops 3 new mixtapes per month. How many years has it been if he drops 45 new tapes?
Answers
It’ll be 15 years since 45 divided by 3 is 15.
Answer:
for the first answer : 36
for the second answer : 1 year and 3 months
Step-by-step explanation:
first answer :
ahe gets kicked out 2 times in 20 mins
6 hours = 6 × 60 mins = 360 mins
let the number of times she gets kicked out in 6 hours / 360 mins be "n"
therefore ;
n= (360×2) ÷ 20 = 36
therefore answer is 36 times.
-----------------------------------------------------------------
second answer :
3 new tapes in 1 month
let the number of years be "n"
therefore:
3×12 = tapes per year = 36 tapes per year
so, n = 45÷36 = 1 (as quotient) year and 3 (as remainder) months.
answer : 1 year and 3 months
