Step-by-step explanation:

Distance between x's (Δx)

This field is calculated automatically, you cannot change it's value manually.

Distance between y's (Δy)

d = √(Δy2 + Δx2) = √(12 + 02) = √1 = 1

What is the equation of a hyperbola with a = 5 and c = 15? Assume that the transverse axis is horizontal.

gogolik [260]

Answer:

$\frac{x^2}{25} -\frac{y^2}{200} =1$

Step-by-step explanation:

Recall that the equation of hyperbola centered at the origin with transverse horizontal axis has the general form:

$\frac{x^2}{a^2} -\frac{y^2}{b^2} =1\\and\,\,\,\, with\\c=\sqrt{a^2+b^2}$

since we know that a = 5 ,and c = 15,we can solve for b:

$15=\sqrt{5^2+b^2} \\15^2=25+b^2\\b^2=200\\$

then the equation of the hyperbola becomes:

$\frac{x^2}{5^2} -\frac{y^2}{200} =1\\\frac{x^2}{25} -\frac{y^2}{200} =1$

What is the value of x? sin(x+34)°=cos(2x+20)°

vfiekz [6]

We know that
if sin A=cos B
then
angle A and angle B are complementary angles
so
A+B=90 degrees
in this problem
(x+34)+(2x+20)=90-------> 3x+54=90----> 3x=90-54-----> x=36/3----> x=12°

the answer is
the value of x is 12 degrees
