Write 7 × 1 + 4 × 1/10 + 6 × 1/1000 in standard form

Answer:

Step-by-step explanation:

Given 30.00 ml of 0.10 m acetic acid and 50.00 ml of 0.100 m koh, the pH of the solution is 12.40

This is the measure of the acidity or the basicity of an aqueous or liquidsolution.

The details that are contained in this question are:

Mole of CH3COOH = 0.1 M

Volume of CH3COOH  = 30 mL

Mole of KOH = 0.1 M

Volume of KOH = 50 mL

mol of (CH3COOH) = 0.1 Mole * 30 mL = 3 mol

mol of (KOH) = 0.1 Mole * 50 mL = 5 mol

From the solution above,

mol of CH3COOH = 3 mol

mol of KOH = 5 mol

3 mol of both substances is going to react

excess KOH remaining = 5 - 3 =  2 mmol

Volume of both Solutions

= 30 + 50 = 80 mL

OH⁻ = 2/80

= 0.025 M

use:

pOH = -log [OH-]

= -log (0.025)

pOH = 1.602

PH = 14 - pOH

= 14 - 1.60

= 12.40

The calculated pH is therefore 12.40

An example of congruence similarity and transformations work is " If the measures of the angles of a triangle are in the ratio 4 : 5 : 9. The triangle is?.

A right triangle is known to be often called right-angled triangle. It is said to be a triangle that is composed of one angle which is at a right angle and two sides which are said to be perpendicular.

So lets take the angles to  be 4x, 5x and 9x

We add them to be 4x + 5x + 9x =180°

18x=180° =

x= 180/18

x = 18

So therefore the angles are:

4×10°

=40°

5×10°

=50°

9×10°

=90°

So therefore since one of the angle is 90° and as such,  the triangle is right angled triangle.

1 small dish = 2 fluid ounces

40 small dishes = 80 fluid ounces

Therefore,

1 fluid 0unces = 0.125 cups

80 fluid ounces = ?

cross multiply

amount of paint filled = 80 × 0.125 = 10 cups

Answer:To pick one mathematic major we have 18 way, and o pick one computer science we have 325 ways, so we have 18 * 325 = 5850 ways to make a combination from them.

Explanation:

The constant ratio of the function f is its growth rate

The function f is an exponential function with a constant ratio of 2

To do this, we simply divide the consecutive function values

From the complete question (see attachment for the table), we have:

f(-1) = 1/4

f(0) = 1/2

f(1) = 1

f(2) = 2

Divide the function values to get the ratio, r

r = f(2)/f(1) = f(1)/f(0) = f(0)/f(-1)

This gives

r = 2/1 = 1 / 1/2 = 1/2 / 1/4

Evaluate the quotients

r = 2 = 2 = 2

The value of r is the same for the three quotients.

Hence, the function f is an exponential function with a constant ratio of 2

The total amount accrued, principal plus interest, with compound interest on a principal of $13,500.00 is $19,377.24.

Given Data

A = P + I where

P (principal) = $13,500.00

I (interest) = $5,877.24

The indefinite integral expressed as an infinite series  is;

[tex]= (\Sigma^{\infty} _{n = 0} (-1)^{n} \frac{1 }{2n + 1} * \frac{(x)^{4n + 3}}{4n + 3}) + C[/tex]

We will first have to look for the Maclaurin series of arctan(x).

We'll recall that from online tables of integral, this Maclaurin series of arctan(x) will have the general formula;

[tex]arctan(x) = \Sigma^{\infty} _{n = 0} (-1)^{n} \frac{x^{2n + 1} }{2n + 1}[/tex]

When we apply that general Maclaurin series of arctan(x) to our question of arctan(x²), we have the expression as;

[tex]arctan(x^{2} ) = \Sigma^{\infty} _{n = 0} (-1)^{n} \frac{(x^2)^{2n + 1} }{2n + 1}[/tex]

⇒ [tex]= \Sigma^{\infty} _{n = 0} (-1)^{n} \frac{(x)^{4n + 2} }{2n + 1}[/tex]

We now integrate the expression that we got above in the following manner to get;

[tex]\int\limitsarctan(x^{2} ) = \int\Sigma^{\infty} _{n = 0} (-1)^{n} \frac{(x)^{4n + 2} }{2n + 1} dx[/tex]

⇒ [tex]= (\Sigma^{\infty} _{n = 0} (-1)^{n} \frac{1 }{2n + 1} * \frac{(x)^{4n + 3}}{4n + 3}) + C[/tex]

Thus, that expression gives us the indefinite integral of arctan(x²) as an infinite series.
