Give your answer rounded to 3 significant figures.
Answer:
10.8 =x
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
8.8 ^2 + 6.2 ^2 = x^2
77.44+38.44=x^2
115.88=x^2
Take the square root of each side
10.76475731=x
Round to 3 significant figures.

Please help, explain in words the steps needed to solve this problem
Answer:
x=6
Step-by-step explanation:
By the Product Rule of Logarithms, the logarithm of the product of numbers is the sum of the logarithms of the numbers.
[tex] log(x) + log(x - 1) = log(x(x - 1)) = log( {x}^{2} - x ) = log(3x + 12) [/tex]
Raise both sides to the power of 10 to eliminate the logs, obtaining:
[tex] {x}^{2} - x = 3x + 12[/tex]
[tex] {x}^{2} - 4x - 12 = 0[/tex]
[tex](x - 6)(x + 2) = 0[/tex]
x = -2 or x = 6. Since x = -2 is extraneous, it follows that x = 6.
Choose the definition for the function.

Casey has a loan for $400 at a rate of 13% annually. How much interest will he pay in 3 years? A) $15. 60 B) $52. 00 C) $156. 00 D) $556. 0.
Casey will pay $156.00 in 3 years, the correct option is C.
What is the rate of interest?
The interest rate is the amount a lender charges a borrower and is a percentage of the principal—the amount loaned.
Given
Casey has a loan for $400 at a rate of 13% annually.
The interset Casey pay in three years for the loan is given by;
[tex]\rm Interest = Amount \times Rate \ of \ interest \times Time\\\\Interest = 400 \times 0.13 \times 3\\\\Interest = 156[/tex]
Hence, Casey will pay $156.00 in 3 years.

Andrew’s rotation maps point M(9, –1) to M’(–9, 1). Which describes the rotation?
Answer:
it rotated a 180 degrees or over the y axis
Step-by-step explanation:
Which of the following explains why f(x) = log4x does not have a y-intercept? Check all that apply.
The function f(x) = log4x does not have a y-intercept Because there is no power of 4 that is equal to 0.
What is a logarithm?Exponentiation's inverse function is the logarithm. That is, the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised in order to obtain that number x.
The logarithm counts the number of times the same factor appears in repeated multiplication in the simplest case.
Following are the reason why f(x) = log4x does not have a y-intercept
1. There is no power of 4 that is equal to 0.
2. Its inverse does not have any x-intercepts.
3. f(x) approaches negative infinity.
Hence f(x) = log4x does not have a y-intercept.

Answer:
8 crabs and 2 octopi
Step-by-step explanation:
Let c represent the amount of crabs and o represent the amount of octopi.
We can use this to set up a system of equations:
6c+8o=64
c=4o
We can solve this system using substitution. In this case, we can substitute 4o for c:
6(4o)+8o=64
24o+8o=64
Combine like terms
32o=64
Divide both sides by 32
o=2
Substitute 2 for o to solve for c:
c=4o=4(2)=8
There are 8 crabs and 2 octopi

If 15 men can do a piece of work in 30 days, in how many days can 10 men complete the same work?
Answer:
45
Step-by-step explanation:
n/15=30
therefore n=450
hence n/10 = 45
Answer:
45 days
Step-by-step explanation:
If 15 men = 30 days
1 man=30*15
1 man = 450 days
10 men = 450/10=45

Answer: 3 and 192
Step-by-step explanation:
Answer:
1 % of 300 is 3, because 1 times 300 equals 300 divided by 100 is 3.
64 times 300 equals 19200 divided by 100 is 192.
Therefore the answer of 1 % of 300 is 64 times smaller than 64 % 300. Basically, 64 % of 300 = y and y= 64 (1 % of 300)

Write the sum using summation notation, assuming the suggested pattern continues. 5 - 15 45 - 135.
The sum using summation notation will be - 312. The sum of the following progression is found by the formula as [tex]S_n = \frac{a(1 - r^n)}{(1 - r)}[/tex].
What is geometric progression?Geometric Progression (G.P.) is a sort of sequence in which each successive phrase is obtained by multiplying the prior term by a set number known as a common ratio.
This progression is also known as a pattern-following geometric sequence of integers. Here you may also learn about mathematical progression.
A non-zero value is obtained by multiplying the common ratio by each phrase to obtain the next term 5 - 15 45 - 135.. is an example of a geometric series with a common ratio of -3.
The common ratio will be;
[tex]\rm r= \frac{-15}{3} \\\\ \rm r= -5[/tex]
The first term is 3
So the sum using summation notation will be;
[tex]S_n = \frac{a(1 - r^n)}{(1 - r)} \\\\ S_n = \frac{3(1 - (-5)^4)}{(1 - (-5))} \\\\ S_n =- 312[/tex]
Hence the sum using summation notation will be - 312.
