Answer:

Explained below

Step-by-step explanation:

We know (hopefully) that 100 centimeters is equal to 1 meter.

The expression should essentially be 400/50.

400/50 = 8

Victor would need 8 books to make a tower with the height of 4 meters.

By the way 50 centimeters per book is a pretty hefty book, would be as thick as my hand pointing upwards.

There is 0.01 meters in 1 centimeter

(50cm) x (0.01m/1cm) = 0.5m

Now that we have it in meters we can count how many of (0.5m) and add up until we get to 4m.

He needs 8 books.

Find the standard form of the equation of the ellipse with the given characteristics. Vertices: (4, 0), (4, 14); endpoints of th
saul85 [17]

Answer:

The standard form of the ellipse is \frac{(x-4)^{2}}{9} + \frac{(y-7)^{2}}{49} = 1.

Step-by-step explanation:

The major axis of the ellipse is located in the y axis, whereas the minor axis is in the x axis. The center of the ellipse is the midpoint of the line segment between vertices, this is:

(h, k) =\frac{1}{2}\cdot V_{1} (x,y) + \frac{1}{2}\cdot V_{2} (x,y) (1)

If we know that V_{1} (x,y) = (4,0) and V_{2}(x,y) = (4, 14), then the coordinates of the center are, respectively:

(h,k) = \frac{1}{2}\cdot (4, 0) + \frac{1}{2}\cdot (4,14)

(h,k) = (2,0) + (2, 7)

(h, k) = (4, 7)

The length of each semiaxis is, respectively:

a = \sqrt{(1 - 4)^{2}+(7-7)^{2}}

a = 3

b = \sqrt{(4-4)^{2}+(0-7)^{2}}

b = 7

The standard equation of the ellipse is described by the following formula:

\frac{(x-h)^{2}}{a^{2}}+ \frac{(y-k)^{2}}{b^{2}} = 1

Where:

h, k - Coordinates of the center of the ellipse.

a, b - Length of the orthogonal semiaxes.

If we know that h = 4, k = 7, a = 3 and b = 7, then the standard form of the ellipse is:

\frac{(x-4)^{2}}{9} + \frac{(y-7)^{2}}{49} = 1

Find the type and number of solution for g(x) = x2 -14x = -50
inysia [295]

Answer:

Step-by-step explanation:

x² -14x+50= 0

this equation has 2 solutions because is a quadratic

the solurions are imaginary roots because the discriminant is less then 0

b²-4ac = (-14)²-4*1*50 = 194-200= -6

to find the actual roots use the quadratic formula

O.6 as a mixed number
ella [17]

Answer:

3/5

Step-by-step explanation:

To make 0.6 as a fraction (you can't make it a mixed number because there is no number to the left of the point) place a 1 under it to make it a fraction:

0.6/1

Since you can't have a decimal on a fraction, multiply by 10;

0.6/1 × 10/10 =6/10

Simply your answer (6/10) to get 3/5

PLS HELPS!! THIS IS WORTH 200 PTS!! FIRST ONE ASNWERS CORRECTLY, GETS THE BRAINIEST.
Verizon [17]

Answer:

B) −2

Explanation:

When x is positive then y is positive integer.

When x is negative then y is negative integer.

<u>For Option A</u>

  • y = 2(-3) + 5
  • y = -1              [x is negative so is y]

<u>For Option B</u>

  • y = 2(-2) + 5
  • y = 1               [<u>x is negative</u> but <u>y is positive</u>]

<u>For Option C</u>

  • y = 2(1) + 5
  • y = 7               [x is positive so is y]

<u>For Option D</u>

  • y = 2(2) + 5
  • y = 9                [x is positive so is y]
