Answer:

a. alphabet line

Explanation:

Technical drawings are the drawings that help in communicating the designs. These designs are the designs that provide the instruction for the manufacturing of any object. The designs are made with the help of lines and line symbols. Line symbols are termed to be alphabet of lines. They help the designers to draw the designs with accuracy. Various lines are drawn that differ in terms of thickness and darkness. These variations helps the designers to mark the design accurately.

If sin(1/x^2+1) is an antiderivative for f(x) then.

STatiana [176]

The limit from 1 to 2 of the given antiderivative is; -0.19865

<h3>What is the Limit of the Integral?</h3>

We are given the antiderivative of f(x) as sin(1/(x² + 1)). Thus, to find the limit from 1 to 2, we will solve as;

$\int\limits^2_1 {(sin\frac{1}{x^{2} + 1} )} \, dx = {(sin\frac{1}{2^{2} + 1} )} - {(sin\frac{1}{1^{2} + 1} )}$

⇒ (sin ¹/₅) - (sin ¹/₂)

⇒ 0.19866 - 0.47942

⇒ -0.19865

Complete Question is;

If sin(1/(x² + 1)) is an anti derivative for f(x), then what is the limit of f(x)dx from 1 to 2?

In a survey of employee satisfaction, 60% of the employees are male and 45% of the employees are satisfied. What is the probabil

melamori03 [73]

Answer:

The probability of being a male and a satisfied employee is 27%

Explanation:

The probability of being a male P(m) = 60% = 60/100 = 0.6

The probability of being a satisfied employee P(s) = 45% = 45/100 = 0.45

Mathematically, the probability of being a male and satisfied = Probability of being a male * Probability of being a satisfied employee = P(m) * P(s) = 0.6 * 0.45 = 0.27

or simply 27/100 which is same as 27%

How many electrons pass through a 20-ohms resistor in 10 min if there is a potential drop of 30 volts across it?

tangare [24]

The number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.

<h3>What is a resistor?</h3>

In an electronic circuit, a resistor is an electrical component that limits or regulates the flow of electrical current.

Given, the resistance is 20 ohms.

The potential difference is 30 volts

Time is 10 minute

By the formula of current
