taurus [48]

Answer:

21. 123 22. 6.86 or 6/ 6/7 23. 90

Step-by-step explanation:

21. (6+4)² + (22+10÷2)

(10)² + (22 + 5)

100 + 27

127

22. (11+42-5) ÷ (11-4)

48 ÷ 7

6.85 or 6 6/7

23. (17-3) × (14 - 6) -22

Write the equation of the conic section with the given properties:

timurjin [86]

Answer:

$\frac{x^2}{64} + \frac{y^2}{25} =1$

Step-by-step explanation:

An ellipse with vertices (-8, 0) and (8, 0)

Distance between two vertices = 2a

Distance between (-8,0) and (8,0) = 16

2a= 16

so a= 8

Vertex is (h+a,k)

we know a=8, so vertex is (h+8,k)

Now compare (h+8,k) with vertex (8,0) and find out h and k

h+8 =8, h=0

k =0

a minor axis of length 10.

Length of minor axis = 2b

2b = 10

so b = 5

General formula for the equation of horizontal ellipse is

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

a= 8 , b=5 , h=0,k=0. equation becomes

$\frac{(x-0)^2}{8^2} + \frac{(y-0)^2}{5} =1$

$\frac{x^2}{64} + \frac{y^2}{25} =1$

Will fan and medal! Identify the transformations that describe the graph of an even function select all that apply.

lara [203]

2 is the only right answer. If it has right/left symmetry, then f(-x) = f(x), meaning it's even.
extra info: 3 and 4 are the same thing
5 works for odd functions (like sin(x))
