Answer:

\mathbf{y^2 -z^2 =1- n^2}

Step-by-step explanation:

Give that:

the surface equation is  x^2 +y^2 -z^2 =1

from the family of traces in x = n given that x^2 +y^2 -z^2 =1 , the equation can be represented as :

n^2 +y^2 -z^2 =1

\mathbf{y^2 -z^2 =1- n^2}

This represents a family of hyperbola for all values of n expects that n = ± 1

So, if n = ± 1,

Then

y^2 - z^2 = 0

(y-z) (y+z) = 0

y = ± z

So, for n = ± 1, it is a pair of line for y = z, y = -z

Can someone please help me with this trigonometry problem. I would highly appreciate it if you did​
dexar [7]

Answer:

x ≈ 16.52

Step-by-step explanation:

Use the tangent ratio in the right triangle to find x

tan36° = \frac{opposite}{adjacent} = \frac{12}{x}

Multiply both sides by x

x × tan36° = 12 ( divide both sides by tan36° )

x = 12 / tan36° ≈ 16.52 ( to 2 dec. places )

The function f(x) = 4(4)x represents the growth of a fly population every year in a remote swamp. Jackie wants to manipulate the
Sauron [17]

The function f(x) = 4(4)x represents the growth of a fly population every year in a remote swamp.

calculates three times a year, not just once a year.

f(x)= 4(4)^x

3 times a year

so x becomes 3x

f(x)= 4(1+r)^{3x}

4(4)^x=4(1+r)^{3x}

Take log on both sides

log(4)^x=log(1+r)^{3x}

log(4)^x=log(1+r)^{3x}

Use log property and move exponent before log

xlog(4)=3xlog(1+r)}

Divide both sides by x

log 4 = 3 log(1+r)

Solve for '1+r'

log 4 = log(1+r)^3

Remove log from both sides

4 = (1+r)^3

take cube root on both sides

1.584740= 1+r

1+r = 1.59

f(x)= 4(1+r)^{3x}

so equation becomes

f(x)= 4(1.59)^{3x}

1+r = 1.59

subtract 1 from both sides

So r= 59 = 59%

So growth factor is 59%

Answer is option C

One number is 16 more than a second number. The sum of the first number and twice the second number is 139. What is the answer ?
Nezavi [6.7K]
Answer first number  = 57  second number = 41
x= 16 + y
x + 2y = 139

16+ y + 2y =139
16 + 3y =139
16-16 +3y = 139-16
3y = 123
3/3y = 123/3
y= 41

x= 16+y
x = 16+41
x= 57
