zubka84 [21]

Multiplicand is the number that gets multiplied, multiplier is the number that you are multiplying by, product is the result of mulptiplication multiplicand by multiplier.

Let a be a multiplicand, b be a multiplier and c be a product, then

a·b=c.

To check the correctness of the answer to a multiplication example, you should divide the product c by the multiplier b:

c÷b=a.

Answer: correct choice is A.

Work out the gradient of the line joining the points (2, 3) and (5,7)

Debora [2.8K]

Answer:

The gradient of the line joining the points $P(x,y) = (2,3)$ and $Q(x,y) = (5,7)$ is $\frac{4}{3}$ .

Step-by-step explanation:

The gradient of the line joining two distinct point on a plane is represented by the slope of a secant line ( $m_{PQ}$ ), that is:

$m_{PQ} = \frac{y_{Q}-y_{P}}{x_{Q}-x_{P}}$ (1)

If we know that $P(x,y) = (2,3)$ and $Q(x,y) = (5,7)$ , then the gradient of the line is:

$m_{PQ} = \frac{7-3}{5-2}$

$m_{PQ} = \frac{4}{3}$

The gradient of the line joining the points $P(x,y) = (2,3)$ and $Q(x,y) = (5,7)$ is $\frac{4}{3}$ .

Find the area???????

Naily [24]

It's obviously none of the above because the true area will have a square root of 3 in it because of the equilateral triangle. They want us to find the approximate area. When I was in school the difference between an approximation and the exact answer was greatly stressed but that seems to be fading of late.

That's a rectangle less an equilateral triangle. The area of an equilateral triangle is $\dfrac{\sqrt{3}}{4} s^2$ which is easily derived but I won't bother here.

$A = 18(8) - \dfrac{\sqrt 3}{4} (8^2) = 144 - 16 \sqrt 3 \approx 116.3$

Answer: b
