Answer:

see below

Step-by-step explanation:

10c + 5 < 45

Subtract 5 from each side

10c + 5-5 < 45-5

10c < 40

Divide by 10 on each side

10c/10 < 40/10

c < 4

Open circle at 4 and the line going to the left

A method for determining whether a critical point is a minimum. True or false?

natita [175]

Answer:

We can find if a critical point is a local minimum or maximum by looking at the second derivatives.

Step-by-step explanation:

If you take the first derivative, you will find the slope at the given point, which if it is a minimum or a maximum will be 0.

Then we take the second derivative. If that number is a positive number, then we have a local minimum. If it is a negative number, then it is a local maximum.

A sum of money was divided between Riaz ad Ali in the ratio of 3:2. Riaz received the larger share. Write the amount each receiv

sasho [114]

Riaz : Ali
3 : 2

Add the two values; so 3 + 2 is 5

Then 100/5 = 20

So: 20 x 3 = 60
and 20 x 2 = 40

Riaz = 60%
Ali = 40%

Then write 60% and 40% as a fraction:
60% = 3/5 (3 over 5)
40% = 2/5 (2 over 5)

The answers are in bold :)

Answer:

286 mm²

Step-by-step explanation:

A trapezium is given with ,

Parallel sides = 24mm , 28 mm
Height = 11mm .

The area is given by :-

$:\implies$ Area = 1/2 ( b₁ + b ₂) × h

$:\implies$ Area = 1/2 ( 24 + 28)×11 mm²

$:\implies$ Area = 1/2 × 52× 11mm²

$:\implies$ Area = 286 mm²

<h3>Hence the area of the trapezium is 286 mm².</h3>
