Arlecino [84]

Answer:

9/10 < 19/20

Step-by-step explanation:

9/10 and 19/20

2*9/2*10 and 19/20

18/20 < 19/20, so

9/10 < 19/20

Find the equation of the sphere if one of its diameters has endpoints (-8, -3, -10) and (-6, 1, -4) which has been normalized so

alex41 [277]

Answer:

The equation is $x^2 + y^2 +z^2 + 14 x + 3y \ + 14z + 86.25=0$

Step-by-step explanation:

From the question we are told that

The diameter endpoints is (-8, -3, -10) and (-6, 1, -4)

Generally the equation of a sphere with center coordinates (a, b , c ) and radius r is mathematically represented as

$(x - a )^2 + (y -b )^2 + (z -c)^2 = r^2$

Now since we are given the endpoints of the diameter then we can obtain the center coordinates as follows

$(a, b , c) = [ \frac{ -8 +(-6)}{2} , \frac{-3 + (1)}{ 2} , \frac{ -10 + (-4)}{2} ]$

$(a, b , c) = [ -7 , -1.5 , -7 ]$

Now the length of the diameter is evaluated as

$|d| = \sqrt{ (-8 - (-6 ))^2 + ( -3 - (1) )^2 + ( -10 - (-4))^2 }$

$|d| = \sqrt{56 }$

$|d| = \sqrt{4 * 14 }$

$|d| = 2 \sqrt{ 14 }$

Now the radius is mathematically represented as

$r = \frac{|d|}{2}$

$r = \frac{ 2 \sqrt{14} }{2}$

$r = \sqrt{14}$

$(x - -7 )^2 + (y --1.5 )^2 + (z --7)^2 = ( \sqrt{14} )^2$

$(x +7 )^2 + (y +1.5 )^2 + (z +7)^2 = 14$

$x^2 + 14 x + 49 + y^2 + 3y + 2.25 +z^2 14z + 49 = 14$

$x^2 + y^2 +z^2 + 14 x + 3y \ + 14z + 86.25=0$

A bond that appreciates 4% per year will be worth $146 in five years. find the current value.

Anastasy [175]

Answer:

$120

Step-by-step explanation:

Let the initial value of bond be $X

The future value of any bond is calculated by formula

FV= PV(1+r)^n

where

FV is future value of bond
PV is present value of bond
r is the rate that at which value of bond appreciate
n is the number of years of maturity

In the problem given

FV= $146

r = 4% = 0.04 (dividing 4 by 100 we get 0.04)

n = 5

substituting these value in formula

$146 = X(1+0.04)^5\\=> X = 146/1.04^5\\=> X = 120$

PV =$X = $120

Hence current value of bond is $120.

Pls help number 1 - 4

Vlad [161]

Answer:

Mean = average. Add up all the numbers, divide it by the number of numbers and there you go.

Median is the middlest number, For example 11, 12, 13, 14, 15. The median would be 13.

Mode is the most often number. For example 11, 11, 12, 13, 14, 14, 14, 15. The answer would be 14.

range is subtracting the lowest number from the highest number. For example, 11, 12, 13, 14, 15. The answer would be 4.
