Answer:
Find roots of x4−81=0 by solving for x. x=3,−3
Step-by-step explanation:
The given equation [tex]x^4[/tex] - 81 = 0 has a total of two real roots x = 3 and
x = -3.
We have,
The given equation [tex]x^4[/tex] - 81 = 0 can be factored as a difference of squares:
[tex](x^2)^2 - 9^2 = 0\\(x^2 - 9)(x^2 + 9) = 0[/tex]
Further simplifying:
(x - 3)(x + 3)(x² + 9) = 0
From this factorization, the equation has two linear factors (x - 3) and
(x + 3) and one quadratic factor (x² + 9).
The linear factors, (x - 3) and (x + 3), will each provide one real root since they are linear equations.
x = 3 and x = -3.
The quadratic factor (x² + 9) has no real roots.
This is because the discriminant (b² - 4ac) of the quadratic equation is negative (a = 1, b = 0, c = 9), indicating that there are no real solutions.
Therefore,
The given equation [tex]x^4[/tex] - 81 = 0 has a total of two real roots,
x = 3 and x = -3.

10m + 40 = 9m + 27
10m - 9m = 27 - 40
m = -13
Answer:
m = - 13
Step-by-step explanation:
2/3 (m + 4) = 1/5 (3m+9)
2/3m + 8/3 = 3/5m + 9/5
2/3m - 3/5m = 9/5 - 8/3
10/15m - 9/15m = 27/15 - 40/15
1/15m = - 13/15
m = - 13/15 / 1/15
m = - 13/15 * 15
m = - 195/15
m = - 13

If you square a googol, how many zeros will the answer have? Show your reasoning.
Answer:
200 zeros
Step-by-step explanation:
1 googol is the number 1 followed by a hundred zeros, right? Right. Using 'Laws of Indices', for instance, 10^2=100, ie 10×10=100. The number of zeros will always be the sum of the number of zeros of the multiplier and multiplicand. More example, 100×100=10000. So, I think it's reasonable to say that 1 googol×1 googol= the number one followed by two hundred zeros ♀️

Answer:
1. $503.08
2. 5071
Step-by-step explanation:
1. Perimeter = (pi × r) + d
= (3.14 × 27/2) + 27
= 69.39
Cost: 69.39 × 7.25 = $503.0775
2. 17 × (pi × d)
17 × 3.14 × 95
5071.1 feet
Step-by-step explanation:
Step 1: Answer the first question
Find the perimeter: [tex]P = (\pi *r)+d[/tex] But... let π be 3.14
[tex]P = (3.14 * \frac{27}{2}) + 27[/tex]
[tex]P = 42.39 + 27[/tex]
[tex]P = 69.39[/tex]
Find the price: $7.25 per foot
[tex]7.25 * 69.39[/tex]
[tex]\[/tex][tex]503.0775[/tex]
Answer: [tex]\[/tex][tex]503.0775[/tex]
Step 2: Answer the second question
Find the amount traveled: [tex]P = revolutions*\pi *d[/tex] But... let π be 3.14
[tex]P = 17 * 3.14 * 95[/tex]
[tex]P = 53.38 * 95[/tex]

The Service Club is choosing members at random to attend conferences in Sheboygan, Madison, La Crosse, and Green Bay. There are 15 members in the club, how many ways can they choose someone to go to the Sheboygan conference, someone different for the Madison conference, someone else for La Crosse, and one last person for Green Bay? SHOW YOUR WORK.
Answer:
There are 32760 ways to pick the members
Step-by-step explanation:
For the first place you have 15 possibilities, since every member of the club is available. For Madison you will have only 14, since you cant pick the same member than the one you picked for Sheyoygan. For the same argument, you will have 13 possibilities available for La Crosse, and only 12 for Green Bay.
We have to pick a combination using the possibilities that we have, thus, you have to multiply all 4 possibilities toguether to find the amount of ways to choose members to attend the conferences. This means that you will have a total of 15*14*13*12 = 32760 possibilities in total.

Step-by-step explanation:
first start with the triangle
to find the base, subtract 8 from 16
to find height subtract 7 from 13

A.one line
B.parallel lines
C.intersecting lines
Answer:
A. One line
Step-by-step explanation:
Let rearrange the system of equations into explicit forms:
[tex]y = -2\cdot x - 5[/tex]
[tex]6\cdot x + 3\cdot y = -15[/tex]
[tex]3\cdot y = -6\cdot x - 15[/tex]
[tex]y = -2\cdot x - 5[/tex]
The second equation is identical to the first one, which means that there is just one line.

Mattie is making a collar for her dog. She needs to buy some chain, clasp, and a name tag. She wants the chain to be 40 cm long. On meter of chain costs $9.75. The clasp is $1.29 and the name tag is $3.43. How much will it cost to make the collar? Estimate to check if your answer is reasonable.
Answer: $8.62
Step-by-step explanation:
Mattie wants to make a collar for her dog. She needs to buy some chain, clasp, and a name tag. Mattie wants the chain to be 40 cm long. On meter of chain costs $9.75, the clasp is $1.29 and name tag is $3.43.
Since 100 centimeters = 1 metre. Mattie needs 40cm and 1 meter of chain costs $9.75, cost of the chain Mattie needs will be:
= 40/100 × 9.75
= 2/5 × 9.75
= $3.90
Chain(40cm) = $3.90
Clasp = $1.29
Name tag = $3.43.
Cost to make collar will be:
= $3.90 + $1.29 + $3.43
= $8.62
