The Diagram Shows A Sphere With Center O And A Radius Of 4 Inches That Has Been Cut By A Plane. The Cross-sectionformed

Answers

Answer 1

Answer:

A circle.

Step-by-step explanation:

Ok, any plane has a vector normal to it.

Then the plane that cuts the sphere, has a normal vector.

If we draw that normal vector such that it passes through the center of the circle, we can think of this as the "axis" of a cylinder.

Such that when we step on any point of that vector, all the points of the spere that can be reached with a perpendicular line to the vector (like the radius in polar coordinates) are at the same distance of the vector.

Then we can conclude that when we cut a sphere with a plane, the cross-section will be always a circle.

Then the shape that is a representation of the cross-section is a circle.

ln -3x + ln 4 = ln 58​

Answers

9514 1404 393

Answer:

  x = -29/6 = -4 5/6

Step-by-step explanation:

The equation simplifies to ...

  ln(-3x·4) = ln(58)

Taking antilogs, the equation becomes ...

  (-3x)(4) = 58

Dividing by -12 shows us the value of x.

  x = -58/12

  x = -29/6 = -4 5/6

__

The applicable rule of logarithms is ...

Write the point -slope form of the equation of the line (-2,5), slope =6

Answers

Answer:

y - 5 = 6(x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 6 and (a, b) = (- 2, 5) , then

y - 5 = 6(x - (- 2)) , that is

y - 5 = 6(x + 2)

Please answer this question needed ASAP !

Answers

Answer: None of them. It should be 150 degrees.

See the explanation below for more details

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

Explanation:

To convert from radians to degrees, we multiply by the factor (180/pi)

The formula we can use is

y = (180/pi)*x

where x is the angle in radians, and y is the angle in degrees

Plug in x = (5/6)pi and evaluate

y = (180/pi)*x

y = (180/pi)*(5/6)*pi

y = (180/pi)*(5pi/6)

y = (180*5pi)/(pi*6)

y = (180*5)/(6)

y = (6*30*5)/(6)

y = (30*5)/(1)

y = 150

So the angle (5/6)pi radians, aka 5pi/6 radians, is equivalent to 150 degrees. Unfortunately this answer choice isn't listed. You'll have to let your teacher know there's a typo somewhere.

Kyle is buying a $220 bicycle if the bicycle is on sale for 35% off how much will he save

Answers

Answer:

$77

Step-by-step explanation:

Okay so first, we know that the bicycle is 220 dollars. So we got to  multiply that to the percent. We can't muiltiply it into the percent yet so we turn that percent into 0.35

220 * 0.35

This equals to 77. That's the answer but it's not that simple, cause we aren't finished!

So we know that 35 percent of 220 is 77 dollars. So subtract that to 220!

220 - 77

This is equal to 143. Now how much will he save? He will save 220 - 143, which is 77! That's how we know the answer! I'm sure this is correct, if itsn't please comment! Have a great day!

Answer:

$143

Step-by-step explanation you wanna see how much 35% is out of 220

35% = 0.35

220 * 0.35 = 77 = discount

Now you want to see how much it will be when the discount is applied

220-77 = 143

The bicycle is $143 when discount is applied, you save $77

Answers

Answer:

361,899

hope this helps

Answer:

350,000

Step-by-step explanation:

1,500,000 - 1,138, 101 = 361,899

361,899 - 350,000 = 11,899

400,000 - 361,899 = 38,101

11,899 is less than 38,101

So, 350,000 is the answer.

y-intercept: [tex](0,-\frac{5}{2} )[/tex]

x-intercept: [tex](-2,0)[/tex]

Step-by-step explanation:

Hi there!

Important things to note:

the y-intercept occurs when x=0the x-intercept occurs when y=0

1) Find the y-intercept

[tex]-5x-4y=10[/tex]

Substitute x with 0

[tex]-5(0)-4y=10\\0-4y=10\\-4y=10[/tex]

Divide both sides by -4

[tex]\frac{-4y}{-4} =\frac{10}{-4} \\y=-\frac{5}{2}[/tex]

Therefore, the y-intercept is [tex]-\frac{5}{2}[/tex]. When written in (x,y) form, x will always be 0 while y is the y-intercept:

[tex](0,-\frac{5}{2} )[/tex]

2) Find the x-intercept

[tex]-5x-4y=10[/tex]

Substitute y with 0

[tex]-5x-4(0)=10\\-5x-0=10\\-5x=10[/tex]

Divide both sides by -5

[tex]-5x=10\\\frac{-5x}{-5}= \frac{10}{-5} \\x=-2[/tex]

Therefore, the x-intercept is -2. When written in (x,y) form, x will always be the x-intercept while y is always 0:

In 2017 the population of Rexburg, Idaho was 28,337 people. The population was expected to grow at a rate of about 1.26% per year. Based on these numbers, what would we predict the population of Rexburg will be in the year 2022?

(Round to the nearest whole number.)

Answers

Answer:

30,122

Step-by-step explanation:

This probably isn't the fastest way to solve but....

28,337x1.26%= 357

357x5=1785

28,337+1785=30,122

The 5 came from the # of years the population is increasing

We are required to find the population of Rexburg will be in the year 2022

The population of Rexburg will be in the year 2022 is 30,122 people

Given:

2017 population = 28,337 people

Growth rate per year = 1.26%

let

n = number of years between current and predicted

= 2022 - 2017

n = 5 years

Yearly growth rate = 28,337 × 1.26%

= 28,337 × 0.0126

= 357.0462

Predicted population in 2022 = 2017 population + (357.0462 ×5)

= 28,337 + 1,785.231

= 30,122.231

Approximately, 30,122 people in 2022.

Therefore, the population of Rexburg will be in the year 2022 is 30,122 people

Answers

Answer:

the axis of symmetry would be: b. x=2

The equation of the axis of symmetry of the parabola will be x = 2. Then the correct option is B.

What is the equation of the parabola?

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.

Then the equation of the parabola will be given as,

y = a(x - h)² + k

The equation is given below.

y = 3x² - 12x + 11

Convert the equation into a vertex form. Then we have

y = 3x² - 12x + 11

y = 3x² - 12x + 12 - 1

y = 3(x² - 4x + 4) - 1

y = 3(x - 2)² - 1

The equation of the axis of symmetry of the parabola is given as,

x - 2 = 0

x = 2

The equation of the axis of symmetry of the parabola will be x = 2. Then the correct option is B.
