Find an equation of the line tangent to the curve √xy + 4y = 39 at the point (1,9)?
evablogger [386]
Find the derivative of the curve to find the line slope at the given point

sqrt(xy) + 4 dy/dx = 39

0.5(xy)^(-0.5) * (y + x dy/dx) + 4dy/dx=  0

No need to amplify simply plug in the given point ( 1,9)

0.5 ( 1 * 9)^(-0.5)* ( 9 + dy/dx) + 4dy/dx  = 0 

Solve for dy/dx

1/6( 9  + dy/dx)  = -4dy/dx

9 + dy/dx = -24 dy/dx

-25dy/dx = 9

dy/dx = -9/25

as your question implies , you know the rest of the steps.

tatyana61 [14]

Answer:

.

c)"At least 1 O+" is equivalent to "not none O+" (forgive the incorrect English).

P(not none O+)+P(none O+)=1

P(not none O+)=1-P(none O+)

P(not none O+)=1-0.00491

P(at least 1 O+)=0.995

Write -74.5 as a mixed number.
seraphim [82]

Answer:

-74 10/5

Step-by-step explanation:

first you will write the decimal number in fraction form which will be,

-74.5 = -745/10

now, on diving we will get,

74 as quotient and 5 as remainder, 10 as divisor.

now mixed fraction is, quotient divisor/remainder

the answer will be -74 10/5

•you can solve it to get the fraction you got previously as, =(-74 X10 + 5)/5 you will get the fraction in question.

I got a little help from my tutors at Gauthmath app, you can get it too. I would suggest you this app. really cool app.

<em>Hope </em><em>my </em><em>answer </em><em>helps.</em>
