MATH math help thanks (pls provide workings)

Answer:

At the point where x = 2.

Step-by-step explanation:

First find the derivative which gives us the gradient of the tangent at any point on the curve:

y = 5x^2 - 16x

y' = 5*2 x^(2-1) - 16 x(1-1)

y' = 10x - 16.

y' is the gradient at point of coordinate x.

So when the gradient = 4:

4 = 10x - 16

10x = 20

x = 2.

The pilot of a Coast Guard patrol aircraft on a search mission had just spotted a disabled fishing trawler and decided to go in

Svetllana [295]

Answer:

$\frac{dD}{dt}= 181\frac{168}{1600}$

Step-by-step explanation:

h= 1000 ft

dx/dt= 232 ft/sec

D= 1600 ft

First, we have to find a distance x ( shown in the figure)

applying pythagorus theorem

D^2= h^2+x^2................1

x^2= D^2-h^2

= 1600^2-1000^2

x^2= 1560000

x=1248.99 m

Now we can find out how fast the aircraft is receding from the trawler

( notice that the height is not changing)

so differentiating equation 1 w.r.t t we get

$\frac{d}{dt} (D^2)= \frac{d}{dt}(h^2+x^2)$

2DD'= 2hh'+2xx'

$D\frac{dD}{dt}= h\frac{dh}{dt}+x\frac{dx}{dt}$

now putting values we get

$1600\frac{dD}{dt}= 1000\times0+232\times1249$

$\frac{dD}{dt}= 181\frac{168}{1600}$

Which expression is equivalent to t2 – 36?

defon

Answer:

(t + 6)(t - 6)

Step-by-step explanation:

(t - 6)(t + 6)

(t . t) + (t . (6) + ((-6) . t) + ((-6) . 6)

= t² - 6t + 6t - 36

= t² - 36

so,

t² - 36 = (t + 6)(t - 6)
