bedmas 10+45/9-(14/2)=
Answers
Answer:
8.
Step-by-step explanation:
1. In PEMDAS, parenthesis always comes first. In this equation, 14 divided by 2 is in parenthesis. this equals 7. Now the equation looks like the following: 10+45/9-(7).
3. In this equation, there are no exponents, nor is there multiplication, so we move on to division. The only division left in this equation is 45 divided by 9, which is equal to 5. Now the equation looks like the following:
10+5-(7)
4. Next in PEMDAS comes addition, which in this case is 10 plus 5, which is equal to 15. Equation presently: 15-(7)
5. Lastly, subtraction. 15 minus 7= 8, therefore the overall answer is 8.

Give an example of an equation that crosses the x-axis at x=3 and x=-8.
This is a problem on my math homework that I’ve been stuck on. Does anyone know how to help?
Answers
The *graph of a function* (and not an equation) f(x) crosses the x-axis for any value of x such that f(x) = 0. We call x a root of f(x) in that case.
The simplest function with roots at both x = 3 and x = -8 is
f(x) = (x - 3) (x + 8)
since
f(3) = (3 - 3) (3 + 8) = 0 • 11 = 0
and
f(-8) = (-8 - 3) (-8 + 8) = -11 • 0 = 0

A violates the rule of y <= x + 1, because 3 > 1 + 1
C violates the rule of y <= x + 1, because 5 > 0 + 1

Rename 5/6 and 14/15 using the least common denominator.
Answers
Answer:
[tex]\frac{25}{30}~and~\frac{28}{30}[/tex]
Multiply 5 by 5 to get your first parameter.[tex]5 * 5 = 25[/tex]
Multiply 6 by 5 to get the denominator, or your second parameter.[tex]5 * 6 = 30[/tex]
For the second fraction, [tex]\frac{14}{15}[/tex], you need to multiply both parameters by 2, similar to before, but we now must use a different number, otherwise, the denominators will not be the same.[tex]14 * 2 = 28[/tex]
Now, multiply 15 by 2[tex]15 * 2 = 30[/tex]
The last step is to put these numbers you gathered into fractions. The bigger number always goes on the bottom, referred to as the denominator, while the smaller number, referred to as the numerator, always goes on the top.[tex]25~and~30 -- > \frac{25}{30}[/tex]

Answer:
8.6 mile
Explanation:
[tex]\sf equation \ follows : \ \ \ d = 1.2116\sqrt{h}[/tex]
d represents the distance a person can see.h represents the height above the ocean.what the captain sees:
[tex]\hookrightarrow \sf d_c = 1.2116\sqrt{15}[/tex]
what the sailor sees:
[tex]\hookrightarrow \sf d_s = 1.2116\sqrt{120}[/tex]
Difference between them:
[tex]\sf \rightarrow 1.2116\sqrt{120} \ - \ 1.2116\sqrt{15}[/tex]
[tex]\sf \rightarrow 8.58[/tex]
[tex]\sf \rightarrow 8.6[/tex] (rounded to nearest tenth)
Answer:
8.6 miles (nearest tenth)
Step-by-step explanation:
[tex]d=1.2116\sqrt{h}[/tex]
where:
d = approximate distance a person can see (in miles)h = person's height above the ocean (in feet)Captain
Given the Captain is 15 ft above the ocean:
[tex]\implies h = 15[/tex]
Substituting this into the equation:
[tex]\implies d_1=1.2116\sqrt{15}[/tex]
Lookout
Given the lookout is 120ft above the ocean:
[tex]\implies h = 120[/tex]
Substituting this into the equation:
[tex]\implies d_2=1.2116\sqrt{120}[/tex]
Solution
To find how much farther the lookout can see than the captain, subtract the distance the captain can see from the distance the lookout can see:
[tex]\implies d_2-d_1[/tex]
[tex]\implies 1.2116\sqrt{120}-1.2116\sqrt{15}[/tex]
[tex]\implies 1.2116(\sqrt{120}-\sqrt{15})[/tex]
[tex]\implies 8.579906391...[/tex]
[tex]\implies 8.6\: \sf miles\:(nearest\:tenth)[/tex]

Answers
the angle when a circle is divided into 12 angles.
solution:angle at a point is:

Suppose a person is standing on the top of a building and that she has an instrument that allows her to
measure angles of depression. There are two points that are 100 feet apart and lie on a straight line that is
perpendicular to the base of the building. Now suppose that she measures the angle of depression from the
top of the building to the closest point to be 33.5º and the angle of depression from the top of the
building to the furthest point to be 28.3º. Determine the height of the building. (Round your answer to the
nearest tenth of a foot.)
Answers
The building and the person on it are illustrations of elevation and depression
The height of the building is 76.9 feet
How to determine the height of the building?To calculate the building height, we make use of the attached illustration
Considering the triangle DCB in the figure, we have:
tan(B) = DC/BD
Substitute known values
tan(28.3) = DC/(DA + 100)
Cross multiply
(DA + 100) * tan(28.3) = DC
Divide both sides by tan(28.3)
DA + 100 = DC/tan(28.3)
Subtract 100 from both sides
DA = -100 + DC/tan(28.3)
Considering the triangle DCA in the figure, we have:
tan(A) = DC/DA
Substitute known values
tan(33.5) = DC/DA
Make DA the subject
DA = DC/tan(33.5)
Substitute DA = DC/tan(33.5) in DA = -100 + DC/tan(28.3)
DC/tan(33.5) = -100 + DC/tan(28.3)
Evaluate the tangent ratios
0.56DC = -100 + 1.86DC
Collect like terms
-1.86DC + 0.56DC = -100
Evaluate
-1.3DC = -100
Divide both sides by -1.3
DC = 76.9 feet
Hence, the height of the building is 76.9 feet

$1,700 is deposited in an account that pays 6.5% annual interest, compounded annually. What is the balance after 3 years?
Answers
Answer: $2053.51
Step-by-step explanation:
The formula for compound interest is [tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
Where
A = final amount
P = initial principal balance (1700 for this)
r = interest rate (0.065 for this)
n = number of times interest applied per time period (1 for this)
t = number of time periods elapsed (3 for this)
[tex]A=1700(1+\frac{0.065}{1})^{(3)(1)} \\A=1700(1.065})^{3} \\A=2053.51435[/tex]
Rounded that is 2053.51

Find the nth term of this quadratic sequence. 3,11,25,45
Answers
Since you know the sequence is quadratic, we can find constants a, b, and c such that the n-th term of the sequence (denoted by f(n)) is
[tex]f(n) = an^2 + bn + c[/tex]
We're given f(1) = 3, f(2) = 11, and f(3) = 25. (We have three unknowns, so we only need three conditions.) Solve for the constants:
[tex]\begin{cases}f(1) = a + b + c = 3 \\ f(2) = 4a + 2b + c = 11 \\ f(3) = 9a + 3n + c = 25 \end{cases} \implies a=3, b=-1, c=1[/tex]
Then the n-th term of the sequence is
[tex]f(n) = \boxed{3n^2 - n + 1}[/tex]
