The length of the diameter is 2.86 cm rounded to 2 DP

Step-by-step explanation:

The formula of the circumference of a circle is

C = 2πr, where r is the radius of the circle
C = πd, where d is the diameter of the circle

∵ The circumference of a circle is 8.97 cm

- We need to find the diameter of the circle, then we will use

the 2nd formula of circumference above

∵ The circumference = πd

- Substitute the value of the circumference in the formula

∴ 8.97 = πd

- Subtract both sides by π

∴ 2.855 = d

- Round it to 2 decimal places (to the nearest hundredth)

∴ d = 2.86 cm

The length of the diameter is 2.86 cm rounded to 2 DP

G^2 + 4gh; if g = -3 and h = 5

xxTIMURxx [149]

Answer:

Step-by-step explanation:

We know that g = -3 and h = 5

Plugging in the values for g and h you will get:

$g^{2} + 4gh$

$(-3)^{2} + 4(-3)(5)$

$9 + (-60)$

Final answer is $-51$

It's 12 points of u get this right

earnstyle [38]

Answer:

y = -2x + 8

Step-by-step explanation:

When two points are given, the equation of the line passing through the points is given by:

$\frac{y - y_1}{y_2 - y_1} = \frac{x - x_1}{x_2 - x_1}$

where: $(x_1,y_1)$ and $(x_2,y_2)$ are the two points passing through the line.

Here, $(x_1,y_1) = (2,4)$ and $(x_2, y_2) = (3,2)$ .

Substituting in the formula, we have:

$\frac{y - 4}{2 - 4} = \frac{x - 2}{3 - 2}$

⇒ $\frac{y - 4}{-2} = \frac{x - 2}{1}$

⇒ y - 4 = -2x + 4

⇒ y = -2x + 8 is the required equation of the line.
