8 0

Step-by-step explanation:

step 1. f(0) = 0/(0^2 + 1) = 0/1 = 0

step 2. -f(x) = -x/(x^2 + 1)

step 3. f(9) = 9/(9^2 + 1) = 9/82.

I think the answer would have to be D. $0.90.

59,970-58,800=1,170
1,170/52=22.5/25=0.90

Write an equation of the ellipse centered at the origin given its vertex and co vertex

jolli1 [7]

Answer:

$\dfrac{x^2}{49}+\dfrac{y^2}{25}=1.$

Step-by-step explanation:

The equation of the ellipse is

$\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1.$

If the vertex of the ellipse is at point (-7,0), then a=7.

If the co-vertex of the elllipse is at point (0,-5), then b=5.

The equation of the ellipse is

$\dfrac{x^2}{7^2}+\dfrac{y^2}{5^2}=1,$

$\dfrac{x^2}{49}+\dfrac{y^2}{25}=1.$

worty [1.4K]

626. tangent because adjacent and hypotenuse are given. tan= o/a
tan(9)= .1584
o/.1584 = 3954/1
cross multiply.
o= .1584 * 3954
o= 626

Two polygons are similar. The perimeter of the smaller polygon is 66 feet and the ratio of the corresponding side lengths is 3 4

Alisiya [41]

Answer:

Perimeter of the other polygon is 88 feet.

Step-by-step explanation:

We are given that, 'Two polygons are similar'.

Also, the perimeter of the smaller polygon is 66 feet and the ratio of the corresponding side lengths is $\frac{3}{4}$ .

As, we know,

'If two polygons are similar, the ratio of their perimeters is equal to the ratio of their side lengths'.

Thus, we have,

Let, the perimeter of the other polygon = x feet.

$\frac{3}{4}=\frac{66}{x}$

i.e. $x=\frac{66\times 4}{3}$

i.e. $x=\frac{264}{3}$

i.e. x= 88 feet

Thus, the perimeter of the other polygon is 88 feet.
