Please help! I know me have 10 minutes! Find all solutions to 20cos(2pi/5 x) = 10✔️2
Answer: A
Step-by-step explanation:
You have:
[tex]20cos(\frac{2\pi }{5} x)=10\sqrt{2}[/tex]
Begin by dividing both sides by 20 to get:
[tex]cos(\frac{2\pi }{5} x)=\frac{\sqrt{2} }{2}[/tex]
Take the arccosine of both sides to get:
[tex]arccos(cos(\frac{2\pi }{5} x))=arccos(\frac{\sqrt{2} }{2})[/tex]
[tex]\frac{2\pi }{5} x=arccos(\frac{\sqrt{2} }{2} )[/tex]
First of all, lets find the right side. Cosine of what gives sqrt 2 over 2? That would be pi/4, plus 2npi. Another solution would be 7pi/4, plus 2npi. We have:
[tex]\frac{2\pi }{5} x=\pi /4+2n\pi[/tex]
[tex]\frac{2\pi }{5} x=7\pi /4+2n\pi[/tex]
Isolate 'x' to get:
[tex]x=\frac{5}{2\pi } (\pi /4+2n\pi)=\frac{5}{8} +5n[/tex]
[tex]x=\frac{5}{2\pi } (7\pi /4+2n\pi)=\frac{35}{8} +5n[/tex]
What is the fifth term of the sequence?
a = m
an = 2an-1
=
0 2m
O 4m
O 8m
O 16m
Answer:
8m
Step-by-step explanation:
an = 2 an-1 means that each term in the sequence( except the first) is obtained by multiplying the last term by 2, so the first 4 terms are m, 2m, 4m, 8m.
Solve for X. Please help!!!
Answer:
58
Step-by-step explanation:
First, we subtract 32 from 90(90deg-32deg) since the entire corner of the problem is the main area we will be focusing on. We get 58deg, and that's your answer!
Answer:
x = 58
Step-by-step explanation:
Look at the picture I have below.
It shown a complementary and supplementary angle.
As we can see there is complementary and supplementary angle in the given picture you have.
Also note that:
Complementary = 90 degree
Supplementary = 180 degree
Since we are solving for x and it close to complementary thus the equation can be written as:
x + 32 = 90
Subtract both sides by 32
x + 32 - 32 = 90 - 32
90 - 32 = 58
Hence x = 58

You have $5,000 to invest for ten years. The Bank pays simple interest at an annual rate of 5%. Calculate your balance after 10 years.
Answer: $7,500
Step-by-step explanation:
Use the formula: SI = P(1 + rt)
SI = 5000(1 + 0.05[10])
SI = 5000 + 2500
SI = $7,500
After 10 years, your balance should be $7,500
A quadratic equation of the form 0=ax2 bx c has a discriminant value of -16. how many real number solutions does the equation have? -1 0 1 2
The provided quadratic equation, which has a negative discriminant value of -16, has no real number solutions.
What is the discriminant value in a quadratic equation?The standard form of the quadratic equation is,
[tex]ax^2+bx+c=0[/tex]
Here,(a,b, c) is the real numbers and (x) is the variable.
For this equation, the discriminant value can be given as,
[tex]D=b^2-4ac[/tex]
In this equation,
If the discriminant value is positive (D>0), then the equation has 2 real solution.If the discriminant value is equal to zero (D=0), then the equation has 1 real solution.When the discriminant value is negative (D<0), then the equation has 2 imaginary solution.The quadratic equation given as,
[tex]0=ax^2 +bx +c[/tex]
This quadratic equation has a discriminant value of -16. As the value of discriminant is negative, thus it has no real solution.
Hence, the provided quadratic equation, which has a negative discriminant value of -16, has no real number solutions.

Suppose a charity received a donation of $27.9 million. If this represents 22% of the charity's donated funds, what is the total amount of its donated funds?
Round your answer to the nearest million dollars.
well, the total amount is "x", which oddly enough is 100%, and we also know that 22% of that is 27.9 millions, so
[tex]\begin{array}{ccll} \stackrel{millions}{amount}&\%\\ \cline{1-2} x & 100\\ 27.9& 22 \end{array} \implies \cfrac{x}{27.9}=\cfrac{100}{22} \\\\\\ 22x=2790\implies x=\cfrac{2790}{22}\implies x\approx 127[/tex]
I know the answer I just need to know how to solve it. The highlighted is the answer.
[tex]x^2+4x+4 = 8\\\\\implies x^2+2\cdot 2 \cdot x+2^2 = 8\\ \\\implies (x+2)^2 = 8\\\\\implies x+2 =\pm\sqrt 8\\\\\implies x +2 = \pm\sqrt{4 \times 2}\\\\\implies x +2 = \pm2\sqrt 2\\\\\implies x =-2 \pm2\sqrt2[/tex]

How do you recognize an Arithmetic Sequence? Can you find terms within an arithmetic sequence using a formula
Answer:
An arithmetic sequence is an ordered set of numbers where the difference between each consecutive term is the same (this is called the "common difference").
The formula for each term in an arithmetic sequence is:
[tex]\sf a_n=a+(n-1)d[/tex]
where:
a is the first term in the sequenced is the common difference between consecutive termsn is the position of the term in the sequenceExample
Sequence: 3, 10, 17, 24, 31, ...
The first term in the sequence is 3, therefore a = 3
The common difference can be found by subtracting one term from the next: d = 10 - 3 = 7
Substituting these values into the equation for the nth term:
[tex]\implies \sf a_n=3+(n-1)7[/tex]
[tex]\implies \sf a_n=3+7n -7[/tex]
[tex]\implies \sf a_n=7n -4[/tex]
Therefore, if we want to find the 5th term of the sequence, simply input
n = 5 into the found equation:
[tex]\implies \sf a_5=7(5)-4=31[/tex]
Yes we can find terms

Answer:
∠1 = 130°
∠2 = 50°
∠3 = 130°
Step-by-step explanation:
As we can see Angles 1 and 50° are on a straight line. As :
Angles on a straight line add up to 180. So :
50 + ∠1 = 180
∠1 = 180-50
∠1 = 130
As we can angles 1 and 2 are on a straight line. As :
Angles on a straight line add up to 180. So :
∠1 + ∠2 = 180
As we worked out ∠1 we can substitute that in to work out ∠2 :
130 + ∠2 = 180
∠2 = 180-130
∠2 = 50
As we can angles 2 and 3 are on a straight line. As :
Angles on a straight line add up to 180. So :
∠2 + ∠3 = 180
As we worked out ∠2 we can substitute that in to work out ∠3 :
50 + ∠3 = 180
∠3 = 180-50
∠3 = 130
