HELP ASAP: Find a hyperbola's equation with vertices at (-7, 0) + (7, 0) and co-vertices (0, -4) + (0, 4).
Harlamova29_29 [7]

Answer:

16x^2 - 49y^2 = 784

Step-by-step explanation:

as we know that this is the standard equation of hyperbola bcz 1 coordinate of vertices is 0.

since in vertices x coordinate is present and y coordinate is 0 so Tranverse axis of hyperbola is along x axis .

vertices in general = (a,0) and (-a,0)

vertices given = ( 7,0) and (-7 , 0)

so a=7

similarly

co vertices in general = ( 0 , b) and ( 0 , -b)

co vertices given = ( 0, 4) and (0 , -4)

so,

b= 4

now equation for x axis is:

(x2/a2) - ( y2/b2) = 1

by putting values we observe the ans is

16x^2 - 49y^2 = 784

A gardener buys a rake and a pair of gloves for each of the 12 volunteers in the gardening club. Each pair of gloves
matrenka [14]

Let unit cost of one rake be : r

Given : Total number of volunteers = 12

Given : Each pair of gloves cost $8.00

⇒   Cost of 12 pair of gloves for 12 volunteers = (12 × 8) = $96

Given : The gardener spends a total of $300 on both rakes and gloves

⇒   Cost of 12 rakes + Cost of 12 pair of gloves = $300

⇒   12r + 96 = 300

⇒   12r = 204

⇒   r = 17

<u>Answer</u> : Cost of one rake is $17
