Find the point P where the line x = 1 + t, y = 2t, z = -3t intersects the plane x + y - z = -5.

Answers

Answer 1

Replace x, y, and z in the plane's equation with their appropriate parametric equations, then solve for t, then evaluate x, y, and z at this t to find the point P.

[tex]x+y-z=-5[/tex]

[tex](1+t)+2t-(-3t)=-5[/tex]

[tex]6t+1=-5[/tex]

[tex]6t=-6[/tex]

[tex]t=-1[/tex]

[tex]\implies x=0,y=-2,z=-3[/tex]

So the point P is (0, -2, -3).

Answer 2

Here, we are required to find the point, P where the lines:

x = 1 + t x = 1 + ty = 2t x = 1 + ty = 2tz = -3t

intersects the plane x + y - z = -5.

The point, P where the lines intersects the plane is given by;

he point, P where the lines intersects the plane is given by;P (0, -2, 3)

Therefore, to find this point, we have to substitute for x, y and z in the equation of the plane.

Therefore, we have;

1 + t + 2t -(-3t) = -5.therefore 6t = - 6and ultimately t = -1

To get the coordinates of the point P where the lines intersect the plane; we can then find x, y and z by substituting t into each of their equations.

Therefore;

x = 1 + (-1) = 0x = 1 + (-1) = 0y = 2(-1) = -2x = 1 + (-1) = 0y = 2(-1) = -2z = -3(-1) = 3

Therefore, the point, P where the lines intersects the plane is given by;

P (0, -2, 3)

Roslan had a total of $50 in 10-cent coins,20-cent coins and 50-cent coins. The value of his 10-cent coins was 30% of the total value of all his coins. The value of his 20-cent coins was 28% of the total value of all his coins.What was the value of his 50-cent coins?

Answers

Answer:

$21

Step-by-step explanation:

Provided total value = $50

$50 = 5,000 cents.

We are provided,

10 cent coins value = 30%  of total value

= 0.3 [tex]\times[/tex] 5,000 cents = 1,500 cents

Value of 20 cents coin = 28% of total value

= 0.28 [tex]\times[/tex] 5,000 cents = 1,400 cents

Therefore, remaining value of cents = Total value of 50 cents coins

5,000 cents - value of 10-cent coins - value of 20-cent coins = total value of 50 cents coins

5,000 - 1,500 - 1,400 = 2,100 cents = $21

Which means number of 50 cents coin = [tex]\frac{2,100}{50} = 42\ coins[/tex]

Alternatively,

To calculate value of 50 cent coins

Total value = 100%

Value in 10-cent coins + 20-cent coins = 30% + 28% = 58%

Value in 50-cent coins = 100 - 58 = 42%

= $50 [tex]\times[/tex] 42% = $21

One number is 38 less than another number. If the sum of the two numbers is 108, find the two numbers.

Answers

Answer:

The two numbers are 35 and 73.

Step-by-step explanation:

We can solve this problem by creating two simultaneous equations using the information given.

Let number 1 = x

Let number 2 = y

x = y - 38 -> ( 1 )

x + y = 108 -> ( 2 )

We can solve simultaneous equations using substitution or elimination. For this question, we will use substitution as it is the easier and shorter option.

Substitute ( 1 ) into ( 2 ):

x + y = 108 -> ( 2 )

( y - 38 ) + y = 108

2y - 38 = 108

2y = 146

y = 146 / 2

y = 73 -> ( 3 )

Substitute ( 3 ) into ( 1 ):

x = y - 38 -> ( 1 )

x = ( 73 ) - 38

x = 35

Therefore:

x = 35 , y = 73

Kendra is working on her financial plan and lists all of her income and expenses in the spreadsheet below. What is Kendra’s net cash flow? a. $295 b. $285 c. $275 d. $255

Answers

The spreadsheet is missing, so i have attached it.

Answer:

Option A - $295

Step-by-step explanation:

From the spreadsheet, net pay = $2300 and interest earned on savings = $20

Therefore, her total income = $2300 + $20 = $2320

Now,from the spreadsheet, total expenses = 800 + 120 + 90 + 45 + 95 + 80 + 275 + 520 = $2025

Now, net cash flow = Total income - Total expenses

Net cash flow = $2320 - $2025

Net cash flow = $295

Determine if the following relations represent y as a function of x.

Answers

Answers:A) No, it is not a function B) Yes it's a functionC) Not a functionD) Yes it's a functionE) Yes it's a function

================================================

Explanation:

If y has an exponent of 2, 4, 6, etc (basically any even number) then it leads to having inputs with multiple outputs.

Consider something like y^2 = x. If x = 100, then y = 10 or y = -10 are possible. A function can only have exactly one y output for any valid x input. Similar issues happen for things like y^4 = x and so on. So this is why A and C are not functions.

The other equations do not have y values with such exponents, so we can solve for y and have each x input lead to exactly one y output. Therefore, they are functions.

A function assigns the values. The only function that represents y as a function of x is D.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

For any relation to represent a function in terms of x that represents the value of y, the order of y in the function should be equal to 1, therefore, the power of y should be 1, also, the y variable should be alone(Isolated) on one side of the equal sign.

A.) x = y⁴

It represents x in terms of y, therefore, No.

B.) 6x² + y = 4

It represents constant in terms of x and y, therefore, No.

C.) 6x + y² = -1

It represents constant in terms of x and y, therefore, No.

D.) [tex]y = \sqrt{1-x^2}[/tex]

The given function represents y in terms of x, therefore, it is a function that represents y as a function of x.

E.)  -2xy = 1

It represents constant in terms of x and y, therefore, No.

Hence, the only function that represents y as a function of x is D.\

To shop a package, a company charges a one-time fee plus a fee based on the weight of the package. The table below shows the total shipping costs for four packages of different weights.

Answers

Answer:

C = $5 + $1.5(w)

Step-by-step explanation:

Given the following information :

Total shipping cost :

One time fee + fee based on package weight

Given the table :

Weight in pounds - - - - Total shipping cost($)

___4__________________11

___8__________________17

___12_________________23

___16_________________29

We can deduce from the table

For a package that weighs (w) 4 pounds

Total shipping cost = $11

Let one time fee = f

Fee based on weight = r

f + 4(r) = 11 - - - - - (1)

For a package that weighs (w) 8 pounds

Total shipping cost = $17

One time fee = f

Fee based on weight = r

f + 8r = 17 - - - - - (2)

From (1)

f = 11 - 4r - - - (3)

Substitute f = 11 - 4r in (2)

11 - 4r + 8r = 17

-4r + 8r = 17 - 11

4r = 6

r = 6/4

r = 1.5

Put r = 1.5 in (3)

f = 11 - 4(1.5)

f = 11 - 6

f = 5

Hence one time fee = $5

Charge based on weight = $1.5

Hence, Total shipping cost 'C' for a package weighing 'w' will be :

C = $5 + $1.5(w)

What is the runner’s average rate of change between the hours: 0.5 and 2? mph 1.5 and 2.5? mph Average Rate of Change

Answers

Answer:4mph

5mph

Slower

Step-by-step explanation:

The average rate of change for the runner is 0.667 miles per hour².

How to calculate the average rate of change?

To calculate the average rate of change, we follow the following formula:

[tex]a = \frac{v_{2} - v_{1}}{t_{2} - t_{1}}[/tex],

where a is the average rate of change, v₂ is the final speed, v₁ is the initial speed, t₂ is the time for v₂, and t₁ is the time for v₁.

How to solve the given question?

In the question, we are asked to find the runner's average rate of change between the hours 0.5 and 2 with speeds of 1.5 mph and 2.5 mph.

So we take, the initial speed v₁ = 1.5 mph, the final speed v₂ = 2.5 mph, the time for v₁, t₁ = 0.5 hours, and the time for v₂, t₂ = 2 hours.

Thus, we can calculate the average rate of change a, using the formula:

[tex]a = \frac{v_{2} - v_{1}}{t_{2} - t_{1}}[/tex],

or, a = (2.5 -1.5)/(2 - 0.5) = 1/1.5 = 0.667 miles per hour².

Therefore, the average rate of change for the runner is 0.667 miles per hour².

==================================

Explanation:

The last equation is not a function because of the even exponent over the y term. If you apply the fourth root to both sides, you'll end up with y = |x| and y = -|x| as the two possibilities. For any nonzero x, there are multiple y outputs.

The first three equations are functions because we don't have the same issue as the last equation. All exponents for the y terms are odd. Something like y without an exponent really means y^1.
