Answer:

5.9 × 10⁻¹⁶

Step-by-step explanation:

To solve this, you need to convert one of the two numbers to the same power of ten as the other. We can do that by multiplying the first number by 10:

6.7 × 10⁻¹⁶ - 8.2 × 10⁻¹⁷

= 67× 10⁻¹⁷ - 8.2 × 10⁻¹⁷

= (67 - 8.2) × 10⁻¹⁷

= 58.8 × 10⁻¹⁷

= 5.9 × 10⁻¹⁶

Note that we're rounding to the nearest tenth, as the original numbers given were as well.

An automobile travels past the farmhouse at a speed of v = 45 km/h. How fast is the distance between the automobile and the farm

yulyashka [42]

Answer:

$\frac{ds}{dt} = 39.586 km/h$

Step-by-step explanation:

let distance between farmhouse and road is 2 km

From diagram given

p is the distance between road and past the intersection of highway

By using Pythagoras theorem

$s^2 = 2^2 +p^2$

differentiate wrt t

we get

$\frac{d}{dt} s^2 = \frac{d}{dt} (4 + p^2)$

$2s \frac{ds}{dt} =2p \frac{dp}{dt}$

$\frac{ds}{dt} = \frac{p}{s}\frac{dp}{dt}$

$\frac{ds}{dt} = \frac{p}{\sqrt{p^2 +4}} \frac{dp}{dt}$

putting p = 3.7 km

$\frac{ds}{dt} = \frac{3.7}{\sqrt{3.7^2 +4}} 45$

$\frac{ds}{dt} = 39.586 km/h$

what is remainder theorem ? explain how to use remainder thereom and factor theorem for linear polynomial .

elena55 [62]

Basically the Remainder theorem states that the remainder of dividing a polynomial P(x) by (x - a) is given by P(a).

So for example if we divide x^ 2 - 2x + 7 by x - 2 the remainder will be
2^2 - 2(2) + 7 = 7..

If the remainder is 0 then the divisor will be a factor of the polynomial. This is the Factor Theorem and can be used to test if a given polynomial has a factor x-a.
