2 and a half kg of tomatoes- 1.50 per kg.
Since we know how much it costs per kg and we know how many kg's there are (2) we would add 1.50 and 1.50 to make 3. and about half of 1,50 is 75 so I would say <span>£</span>3.75
A vertical pole(AB) 6 feet long casts a shadow(CB) 55 inches long as shown in the attached image. Since the angle of elevation of sun is 
. We hav to find the value of .
Firstly, we will change the dimensions of pole(in feet) to the dimension of shadow( in inches) . So, that the dimensions of pole and shadow are same.
Since, 1 feet = 12 inches.
6 feet = 
inches.
Now, let us consider the triangle ABC in the attached image,
We have to find
= 
= 1.309
Answer:
d. y = 3/4x - b
Step-by-step explanation:
Use the y = mx + b formula to solve the equation. Plug in the known values in to this. After you have done that, you should get:
y = 3/4x - 1
Sorry if i didn't explain well. Hope it helps! :)
The given curve is --- y = x^5 + x^3 - 2x
<span>First derivative to this curve is y' = 5 x^4 + 3 x^2 - 2 </span>
<span>=> Slope (m) = 5 x^4 + 3 x^2 - 2 </span>
<span>For the minimum value of m we calculate dm/dx and put it = 0 </span>
<span>=> d( 5 x^4 + 3 x^2 - 2 ) / dx = 0 </span>
<span>=> 20 x^2 + 6 x = 0 </span>
<span>=> x ( 20 x + 6 ) = 0 </span>
<span>Turning values of x are 0 and - 6 / 20 = ( - 3 / 10 ) </span>
<span>At x = 0 , m = - 2 </span>
<span>and at x = - 3/10 </span>
<span>m = 5 x^4 + 3 x^2 - 2 </span>
<span>=> m = 5 ( - 3 / 10 )^4 + 3 ( - 3 / 10 )^2 - 2 = - 1.68 </span>
<span>Hence at turning points, the slope is minimum at x = 0 and is equal to = - 2 </span>
<span>MINIMUM VALUE OF THE SLOPE = - 2</span>
Answer:
x = 43
