Answer:

20

Step-by-step explanation:

\frac{2}{15} = 40

\frac{2}{15} ÷ \frac{2}{1} = \frac{1}{15}

40 ÷ \frac{2}{1} = 20

Brums [2.3K]

Functions, equations and tables can be represented using graphs

  • The x-intercepts are: 0, 0.35 and 1.53
  • The local maximum is at point (0.17, 0.08), and the local minimum is at point (1.13, -1.07)

The expression is given as:

x^4-3x^2+x

Rewrite the expression as a function

f(x) =  x^4-3x^2+x

See attachment for the graph of the function.

<h3>The x-intercepts</h3>

This is the point where the graph cross the x-axis.

From the attached graph, the x-intercepts are: 0, 0.35 and 1.53

<h3>The local maximum</h3>

From the attached graph, the local maximum is at point (0.17, 0.08)

<h3>The local minimum</h3>

From the attached graph, the local minimum is at point (1.13, -1.07)

<h3>Intervals</h3>
  • The graph increases at interval (-1.30, 0) and (1,13, infinity)
  • The graph decreases at interval (- infinity, 1.30) and (0.35, 1.13)

How do you solve this one 10x^2-25=x^2
solong [7]
10x^2 - 25 = x^2
Take the square root of each side.

\sqrt{x^2} =  \sqrt{10x^2 - 25}
x = 10x - 5i

Find the amount in a bank account if you deposited $10,000 for 25 years at 6.25% interest compounded quarterly.
KengaRu [80]
Ok, so the formula for compound QUARTERLY is A=P(1+ʳ/n)ⁿ<span>ᵗ.
P= The initial amount.
R= The Rate
T= The Time/Number of Years
N= Number of time interest is compounded per year. (In this case its 4 because it compounded QUARTERLY.)

So if you input the numbers, you will get A=10,000(1+0.0625/4)</span>⁴⁽²⁵⁾<span>
Now solve inside the parenthesis.
10,0 00(1.0625/4)</span>⁴⁽²⁵⁾
Now you will need a calculator for the next part...
Do 1.0625/4 and times it by 10,000 .
You will get 0.0265265. You can't for get about the ⁴⁽²⁵⁾.
⁴⁽²⁵⁾=<span>¹⁰⁰
</span>2,656.25¹⁰⁰=
