Answer:

Direct Variation / Proportinal

Step-by-step explanation:

A general form for a direct variation equation is:

$y=kx$

'k' is the constant of proportionality.

We can see that the equation given is in that general form, where 5 is the constant or proportionality, or the slope.

Hope this helps.

Answer : The amount of margarine needed is 1 kg.

Step-by-step explanation :

First we have to convert volume of syrup from mL to L.

Conversion used:

1 L = 1000 mL

or, 1 mL = 0.001 L

So, 225 mL = 0.225 L

Now we have to calculate the amount of margarine needed.

As, 0.225 L of syrup needed 150 g of margarine

So, 1.8 L of syrup needed $\frac{1.5L}{0.225L}\times 150 g=1000g$ of margarine

Amount of margarine needed = 1000 g = 1 kg (1 kg = 1000 g)

Therefore, the amount of margarine needed is 1 kg.

Which two values of x are the roots of the polynomial below? x^2+5x+11

In-s [12.5K]

Answer:

x = -5/2 + i√19 and x = -5/2 - i√19

Step-by-step explanation:

Next time, please share the possible answer choices.

Here we can actually find the roots, using the quadratic formula or some other approach.

a = 1, b = 5 and c = 11. Then the discriminant is b^2-4ac, or 5^2-4(1)(11). Since the discriminant is negative, the roots are complex. The discriminant value is 25-44, or -19.

Thus, the roots of the given poly are:

-5 plus or minus i√19

x = -----------------------------------

2(1)

or x = -5/2 + i√19 and x = -5/2 - i√19
