(20+80 divided by 2x8) divided [(54 divided by 9+14)divided by 4]
Answer:
80
Step-by-step explanation:
Let's write out the equation:
8(20+80/2)/[(54/9+14)/4]
For the first part we get 8(100/2)
Then 50x8
Then 400
For the second part we have (6+14)/4 as we divide 54 by 9. PEMDAS
Then 20/4
Then 5
So our final answer is 400/5 which is 80.
Hope this helps!
The given mathematical statement can be written in the form of mathematical expression as -{x} = {(20 + 80)/(2 x 8)} ÷ [{54/(9 + 14)}/4].
What is function?A function is a relation between a dependent and independent variable.
We can write the examples of function as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is the mathematical statement as -
(20+80 divided by 2x8) divided [(54 divided by 9+14)divided by 4]
We can write the given statement in the form of mathematical expression as -
{x} = {(20 + 80)/(2 x 8)} ÷ [{54/(9 + 14)}/4]
Simplifying, we get -
{x} = {100/16} ÷ {54/23}/4
{x} = 100/16 ÷ 54/92
{x} = 100/16 x 92/54
{x} = 10.64
Therefore, the given mathematical statement can be written in the form of mathematical expression as -{x} = {(20 + 80)/(2 x 8)} ÷ [{54/(9 + 14)}/4].

Complete the inverse function for the function given below.
Answer:
[tex]f^{-1}[/tex](x) = 0.5x + 2
Step-by-step explanation:
let y = f(x) and rearrange making x the subject , that is
y = 2x - 4 ( add 4 to both sides )
y + 4 = 2x ( divide both sides by 2 )
[tex]\frac{y+4}{2}[/tex] = x

PLEASE HELP! Find the accumulated value of an investment of $17,000 at 6% compounded annually for 13 years. (Please show work tho)
9514 1404 393
Answer:
$36,259.78
Step-by-step explanation:
The formula for compound interest is ...
A = P(1 +r/n)^(nt)
where principal P is invested at annual rate r for t years compounded n times per year.
Here, you have P = 17000, r = 0.06, n = 1, t = 13.
A = 17000(1 +0.06)^13 = 17000(2.13292826) = 36,259.78
The accumulated value after 13 years is $36,259.78.

Write given expression in terms of x and y only. Answer the picture pls
Answer:
Step-by-step explanation:
These are really difficult, but one thing I noticed pretty much across the board is that we state our trig ratios in terms of sin and cos using the Pythagorean identity:
[tex]sin^2x+cos^2x=1[/tex], even this one where tangents are involved. Let's begin:
If tan⁻1(x) = u (this is just a substitution to make things easier down the road), then tan(u) = x
If tan⁻1(y) = v, then tan(v) = y.
If that be the case, what we have as a rewrite from our original problem is
sin(u + v) which, according to the identity is:
[tex]sin(u-v)=sin(u)cos(v)-sin(v)cos(u)[/tex] which also tells us that we need those tangents in terms of sines and cosines, as stated earlier. We will take the Pythagorean identity and solve it for both sinx and cosx. Sinx first:
If [tex]cos^2x+sin^2x=1[/tex] then solving for sin:
[tex]\frac{cos^2x}{sin^2x}+\frac{sin^2x}{sin^2x}=\frac{1}{sin^2x}[/tex] (as you can see, I just divided everything by sin-squared):
[tex]cot^2x+1=\frac{1}{sin^2x}[/tex] and
[tex]\frac{1}{tan^2x}+1=\frac{1}{sin^2x}[/tex] and work on eliminating the denominators by multiplying through by sin-squared times tan-squared:
[tex]sin^2x*tan^2x(\frac{1}{tan^2x}+1=\frac{1}{sin^2x})[/tex] which simplifies to
[tex]sin^2x+sin^2x*tan^2x=tan^2x[/tex] and factor out on the left:
[tex]sin^2x(1+tan^2x)=tan^2x[/tex] and solve for sin-squared:
[tex]sin^2x=\frac{tan^2x}{1+tan^2x}[/tex] and take the square root of both sides:
[tex]sinx=\frac{tanx}{\sqrt{1+tan^2x} }[/tex] . Do the same to solve for cos(x) to get:
[tex]cosx=\frac{1}{\sqrt{1+tan^2x} }[/tex] and now we're ready to fill in our formula for sin(u + v):
[tex]\frac{tanu}{\sqrt{1+tan^2u} }*\frac{1}{\sqrt{1+tan^2v} }[/tex] - [tex]\frac{tanv}{\sqrt{1+tan^2} }*\frac{1}{\sqrt{1+tan^2u} }[/tex] and...
since tanu = x and tanv = y:
[tex]\frac{x}{\sqrt{1+x^2}}*\frac{1}{\sqrt{1+y^2}}-\frac{y}{\sqrt{1+y^2}}*\frac{1}{\sqrt{1+x^2} }[/tex] which, in the end, simplifies to
[tex]\frac{x-y}{\sqrt{1+x^2}*\sqrt{1+y^2} }[/tex] and you're done! Yikes to that!!!!

How many times more ?
Answer:
1.3
Step-by-step explanation:
bc for each time x increases by 1, it multiplies by 1.3
i cant think of any other way to explain it
but i hope this helped :D
Answer:
1.3 times
Step-by-step explanation:
f(x)= 68 (1.3) ^x
it, means each year, the expected number of squirrels is 1.3 times, the number the year before.
x=0 so, f(0)=68
New x=1, so f(1)= 68(1.3)¹
= 68 × 1.3
f (1)= f(0) × 1.3
So, 1.3 times

There are no two number that multiply to -10 and add to -7
Answer:
x^2 - 7x - 10
Think about it like this: What two numbers multiply to get -10 and add to get -7?
But no matter what we try, this doesn't work. And that's because x^2 - 7x - 10 is actually prime.
So "Prime" is the correct answer.

Sophie shares her cake with her friends. she gives Lionel a quarter and Helen half of the rest. what fraction remains for her
Answer:
one and a half quaters
Step-by-step explanation:
4/4 is a whole
The they take one 1/4
then that gives you 3/4
which is then 1.5/4 left for you
Answer:
3/8
Step-by-step explanation:
Hi! So what really helps me sometimes is to draw a circle and split it. I shaded 1/4 (Lionel's quarter) first. Now, there is 3/4 of the cake left. Helen has half of the rest, which means she has half of 3/4. 1/2 of 3/4 (which is basically 1/2 x 3/4) = 3/8. This means Helen has 3/8 of the cake. I then split my circle into eighths and shaded in 3. This left me with 3/8 of the cake left for Sophie. This means the fraction that remains for her is 3/8.
I hope this helped :)

find the real solution of the equation.
Answer:
[tex]x = -5 \text{ or } x =3[/tex]
Step-by-step explanation:
We want to find the real solutions to the equation:
[tex]\displaystyle 8^{x^2 + 2x - 15} = 1[/tex]
Recall that any value raised to zero (except for zero itself) is one.
In other words, the exponent must equal zero:
[tex]x^2 + 2x - 15 = 0[/tex]
Solve for x. Factor:
[tex](x+5)(x-3) = 0[/tex]
Zero Product Property:
[tex]x + 5 = 0\text{ or } x - 3 = 0[/tex]
Solve for each case. Hence:
[tex]x = -5 \text{ or } x =3[/tex]
In conclusion, our two real solutions are:
[tex]x = -5 \text{ or } x =3[/tex]
