Someone pls help i need help with my math question

Put these points into an equation IN STANDARD FORM!!!!!!<br><br>(0,2) and (8,0)

zubka84 [21]

The equation of the line in standard form is x + 4y = 8

<h3>How to determine the line equation?</h3>

From the question, the points are given as

(0, 2) and (8, 0)

To start with, we must calculate the slope of the line

This is calculated using

Slope = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) = (0, 2) and (8, 0)

Substitute the known parameters in Slope = (y₂ - y₁)/(x₂ - x₁)

So, we have

Slope = (0 - 2)/(8 - 0)

Evaluate

Slope = -1/4

The equation of the line can be calculated using as

y - y₁ = m(x + x₁)

Where

(x₁, y₁) = (0, 2)

and

m = slope = -1/4

Substitute the known values in the above equation

So, we have the following equation

y - 2 = -1/4(x - 0)

This gives

y - 2 = -1/4x

Rewrite as

1/4x + y = 2

Multiply by 4

x + 4y = 8

Hence, the line has an equation of x + 4y = 8

Use cylindrical coordinates. Find the volume of the solid that lies within both the cylinder x2 + y2 = 25 and the sphere x2 + y2

Inessa05 [86]

Answer:

Step-by-step explanation:

we are asked to find the volume of solid that lies within both the cylinder

$x^2 + y^2 = 25$

and

the sphere $x^2 + y^2 + z^2 = 49.$

Conversion from rectangular to cylindrical is

$x=rcost\\y = rsint\\z=z$

|J| =r

In cylindrical coordinates the volume is bounded by the cylinder r=5 and

$r^2+z^2 =49$

Hence we can write volume as

$\int \int \int dxdydz\\=\\\int _0^5 \int_0^{2\pi} \int_{-\sqrt{49-r^2} } ^{\sqrt{49-r^2} rdzdtdr\\= 2\pi \int _0^5 (2\sqrt{49-r^2} rdr\\=4\pi (-(49-r^2) (2/3)\\= \frac{4\pi}{3} (343-48\sqrt{6} )$

In how many different ways can the

Dafna11 [192]

My answer isn't in your choices so it's probably wrong, but hopefully my approach can give you hints.

The vowels are AEAI
The vowels can be arranged in 4*3*2=24 ways.

The non vowels are MTHMTCS
If the vowels must be together, there have to be in one of the spaces between the non vowels.
If we look at it like this:
-M-T-H-M-T-C-S-
The 4 vowels must go in one of the places marked with a dash.
There are thus 8 places to choose from.

But we must also consider that the non vowels can be arranged in any way. There are 7 of them, so they can be arranged in 7*6*5*4*3*2=5040 ways.

Multiply everything together to get 8*5040*24=967680

Can someone answer this question please?

Slav-nsk [51]

Answer:

Therefore,

(x , y) YES / NO

(-4, -5) Yes, It is a Solution.

(1 , - 3) No, not a Solution.

(9 , 6) No, not a Solution.

(-6 , 2) No, not a Solution.

Step-by-step explanation:

Given:

$4x-7y=19$

To Determine:

Given ordered pair is a solution or not ?

Solution:

For (-4,-5)

Substitute x = -4 and y = -5 in above equation

Left Hand Side = 4 × (-4) - 7 × (-5)

= -16+35

= 19

Right Hand Side = 19

Left Hand Side = Right Hand Side

Satisfied

Hence (-4, -5) is the SOLUTION to 4x - 7y =19 (YES)

For (1, -3)

Substitute x = 1 and y = -3 in above equation

Left Hand Side = 4 × (1) - 7 × (-3)

= 25

Right Hand Side = 19

Left Hand Side ≠ Right Hand Side

Not Satisfied

Hence (1, -3) is NOT the Solution to 4x - 7y =19 (NO)

For (9, 6)

Substitute x = 9 and y = 6 in above equation

Left Hand Side = 4 × (9) - 7 × (6)

= -6

Right Hand Side = 19

Left Hand Side ≠ Right Hand Side

Not Satisfied

Hence (9, 6) is NOT the Solution to 4x - 7y =19 (NO)

For (-6, 2)

Substitute x = -6 and y = 2 in above equation

Left Hand Side = 4 × (-6) - 7 × (2)

= -38

Right Hand Side = 19

Left Hand Side ≠ Right Hand Side

Not Satisfied

Hence (-6, 2) is NOT the Solution to 4x - 7y =19 (NO)

Therefore,

(x , y) YES / NO

(-4, -5) Yes, It is a Solution.

(1 , - 3) No, not a Solution.

(9 , 6) No, not a Solution.

(-6 , 2) No, not a Solution.
