Find parametric equations and symmetric equations for the line. (Use the parameter t.) The line through (4, −5, 2) and parallel to the line x + 5 = y 2 = z − 3

Answers

Answer 1

Answer:

Step-by-step explanation:

From the given information, the symmetric equations for the line pass through(4, -5, 2) i.e ([tex]x_o, y_o, z_o[/tex]) and are parallel to [tex]\dfrac{x+5}{1} = \dfrac{y}{2}= \dfrac{z-3}{1}[/tex]

The parallel vector to the line i + zj+k = ai + bj + ck

Hence, the equation for the line is :

[tex]x = x_o + at \\ \\ x = y_o + bt \\ \\ x = z_o + ct[/tex]

x = 4 + t

y = -5 + 2t

z = 2 + t

Thus, x, y, z = ( 4+t, -5+2t, 2+t )

The symmetric equation can now be as follows:

[tex]\begin {vmatrix} x = 4+ t \\ \\ \dfrac{x-4}{1} = t \begin {vmatirx} \end {vmatrix}[/tex][tex]\begin {vmatrix} y = - 5+2t \\ \\ \dfrac{y+5}{2} =t \end {vmatrix}[/tex][tex]\begin {vmatrix} z =2+t \\ \\ \dfrac{z-2}{1} =t \end {vmatrix}[/tex]

[tex]\dfrac{x-4}{1}= \dfrac{y+5}{2}=\dfrac{z-2}{1}[/tex]

235 people are at RSM summer camp. There are 35 more boys than girls, and 70 fewer adults than girls. How many people of each group are at the camp? PLS DO IT QUICK

Answers

Answer:

Number of girls = 90

Number of boys = 125

Number of Adults = 20

Step-by-step explanation:

Let us represent:

The number of girls = g

The number of boys = b

Number of Adults = a

235 people are at RSM summer camp.

Hence,

g + b + a = 235 .......Equation 1

There are 35 more boys than girls, and 70 fewer adults than girls.

b = g + 35

a = g - 70

Hence we substitute g + 35 for b and g - 70 for a in Equation 1

g + b + a = 235 .......Equation 1

g + g + 35 + g - 70 = 235

3g + 35 - 70 = 235

3g - 35 = 235

3g = 235 + 35

3g = 270

g = 270/3

g = 90

Hence, there are 90 girls in the party.

Number of boys is calculated as:

b = g + 35

b = 90 + 35

b = 125

Number of Adults is calculated as:

a = g - 70

a = 90 - 70

a = 20

How many people of each group are at the camp?

Number of girls = 90

Number of boys = 125

Number of Adults = 20

Answer:

There are 90 girls, 125 boys, and 20 adults.

Step-by-step explanation:

Let x be the number of girls. How many boys were there?

x + 35

How many adults were there?

x - 70

We know that 235 people are at RSM summer camp. Use this to make an equation.

x + (x + 35) + (x - 70) = 235

x + x + 35 + x - 70 = 235

3x - 35 = 235

3x - 35 + 35 = 235 + 35

3x = 270

3x ÷ 3 = 270 ÷ 3

x = 90

x, x + 35, x - 70

90, 125, 20

Which expression is equivalent to StartRoot negative 80 EndRoot? Negative 4 StartRoot 5 EndRoot Negative 4 StartRoot 5 EndRoot i 4 StartRoot 5 EndRoot i 4 StartRoot 5 EndRoot

Answers

Answer:

(4√5)i

Step-by-step explanation:

Complex number is a number in the form a + bi, where both a and b are real numbers. A complex number has two parts, the first part a is the real part of the complex number and the second part b is the imaginary part of the complex number. Also, i = √(-1), hence i² = -1.

Complex numbers can also be graphed on the complex plane.

√(-80) = √(-1) × √(80)

But since √(-1) = i

√(-80) = i × √80 = i × √16 × √5 = i × 4 × √5 = (4√5)i

√(-80) = (4√5)i

Find three consecutive even integers such that when the first integer is
multiplied by the third integer, the result is 2 more than 5 times the
second integer. [Only an algebraic solution will be accepted.]

Answers

Answer:

4, 6, 8

Step-by-step explanation:

Let the three consecutive integers be a, b, and c.

So, first, we know that they are three consecutive even integers. In other words:

[tex]a=2n,b=2n+2,c=2n+4[/tex]

N is any integer, but the 2n ensures that the outcome is even. Since we want to make the subsequent terms also even, we add 2.

We are told that when the first integer (a) is multiplied by the third integer (c), the result is 2 more than 5 times the second integer (b). In other words:

[tex]ac=2+5b[/tex]

Substitute:

[tex](2n)(2n+4)=2+5(2n+2)[/tex]

Distribute both sides:

[tex]4n^2+8n=2+10n+10[/tex]

Add on the right:

[tex]4n^2+8n=10n+12[/tex]

Subtract 10n and 12:

[tex]4n^2-2n-12=0[/tex]

Divide everything by 2:

[tex]2n^2-n-6=0[/tex]

Factor. Find two numbers that when multiplied equals (2)(-6)=-12 and when added equals -1.

3 and -4 works. Thus:

[tex]2n^2-4n+3n-6=0\\2n(n-2)+3(n-2)=0[/tex]

Combine:

[tex](2n+3)(n-2)=0[/tex]

Zero Product Property:

[tex]2n+3=0\text{ or } n-2=0[/tex]

Solve for n:

[tex]n=-3/2\text{ or } n=2[/tex]

So, n is either -3/2 or 2.

That means that a must be either:

[tex]a=2(-3/2)\text{ or } 2(2)[/tex]

Multiply:

[tex]a=-3\text{ or } 4[/tex]

The first answer is not even. So:

[tex]a=4[/tex]

Our first answer is 4.

And our sequence is 4, 6, and 8.

Checking:

4 times 8 is 32.

2 plus 5 times 6 is also 32.

So our answer is correct.

Solve for x
x - 7 = 8

Answers

Answer: x = 15

Step-by-step explanation: In this problem, since 7 is being subtracted

from x, add 7 to both sides of the equation to get x by itself.

On the left side, -7 + 7 will cancel out and

on the right side, 8 + 7 simplifies to 15.

So x = 15.

The value of x in the given equation x - 7 = 8 is 15.

Given that an equation x - 7 = 8, we need to solve for x.

To solve for x in the equation x - 7 = 8, you want to isolate x on one side of the equation.

Follow these steps:

Step 1: Add 7 to both sides of the equation to isolate x on the left side:

x - 7 + 7 = 8 + 7

Simplifying the left side, the -7 and +7 cancel out, leaving:

x = 15

Step 2: Check your solution by substituting the value of x back into the original equation:

x - 7 = 8

Substitute x with 15:

15 - 7 = 8

Simplify the left side:

8 = 8

Since the left side equals the right side, we have verified that x = 15 is indeed the correct solution for the equation.

Hence, the answer is x = 15.

i need help :(

Answers

Answer:

The value of √46 is between 6.5 and 7.

Step-by-step explanation:

We can use perfect squares to solve this problem.

1² = 1

2² = 4

3² = 9

4² = 16

5² = 25

6² = 36

7² = 49

A square root reverses the squaring operation. Therefore, if we take the square root of 49, we will get 7.

So, because 46 fits in the interval 36 < 46 < 49, we can solve this problem.

√36 = 6

√46 = ?

√49 = 7

Therefore, using this information, we can see that clearly the value of 46 is closer to 49, meaning that the square root of 46 is between 6.5 and 7.

Which answer describes the type of numbers that are dense? whole numbers and integers whole numbers but not integers rational numbers and irrational numbers rational numbers but not irrational numbers

Answers


No irrationals are integers. Irrational numbers are by definition *not rational*, and all integers can represented as the rational , and so are rational

Using number sets, it is found that the set of dense numbers is composed by: rational and irrational numbers

---------------

Numbers can be classified as:

Whole numbers: All positive numbers and 0, so: {0,1,2,...} Integer numbers: Positive or negative, not decimal so: {...,-2,-1,0,1,2,....} Rational numbers: Integer plus decimals that can be represented by fractions, that is, they either have a pattern, or have a finite number of decimal digits, for example, 0, 2, 0,45(finite number of decimal digits), 0.3333(3 repeating is the pattern), 0.32344594459(4459 repeating is the pattern). Irrational numbers: Decimal numbers that are not represented by patterns, that is, for example, 0.1033430290339, which can be approximated to the rational 0.1. Real numbers: Rational plus irrational.

---------------

A subset is dense of the rational numbers if all numbers can be approximated to rational numbers, and thus, rational and irrational numbers are dense.

b. As the order quantity increases, annual holding cost increases.
c. As the order quantity increases, annual ordering cost increases.
d. As the order quantity increases, average inventory increases.

Answers

Answer: As the order quantity increases, annual ordering cost increases

Step-by-step explanation:

The Economic Order Quantity (EOQ) is simply referred to as the amount of units that should be added by a company to its inventory with each order in order to minimize total inventory costs such as order costs, holding costs, and shortage costs.

The incorrect option is that "as the order quantity increases, annual ordering cost increases". It should be noted that ordering costs are simply the expenses that are incurred in order for an order to be created and processed to a supplier. It should be noted that as the ordering quantity increases, it doesn't mean that the annual ordering costs also increase.
