Step-by-step explanation:

Line L passes through point (0,2) and (4,0)

If you want to find the gradient of Line L, you can use this formula :

m =  \frac{y_2 - y_1}{x_2 - x_1}

m =  \frac{0 - 2}{4 - 0}

m =  \frac{ - 2}{4}

m =  -  \frac{1}{2}

I really don't understand this. plzz help
Vsevolod [243]

Answer:

x = 25

Step-by-step explanation:

In any triangle, the sum of all 3 angles is ALWAYS 180 degrees. So we can make this into an equation.

4x + 2x+ 10 + x - 5 = 180

Now we combine the like terms.

7x + 5 = 180

Subtract 5 from both sides.

7x = 175

Now divide by 7 on both sides.

x = 25

Mr. Wong predicted that he would sell 45 automobiles. He actually sold 48 automobiles. What are the values of a and b in the tab
iVinArrow [24]

Answer:

<h2>a = 3.45</h2><h2>b = 6.67%</h2>

Step-by-step explanation:

Initial prediction of sales = 45 automobile

Actual amount sold = 48 automobiles

Absolute error ratio a = actual amount sold - initial prediction/initial prediction

Absolute error ratio a = 48-45/45

Absolute error ratio a = 3/45

%error = actual amount sold - initial prediction/initial prediction * 100%

% absolute error = 48-45/45 * 100

% absolute error = 3/45 * 100

% absolute error b = 6.67%

Answer:

⅓ m/s

Step-by-step explanation:

Area of a square is:

A = s²

Take derivative of both sides with respect to time:

dA/dt = 2s ds/dt

Given that dA/dt = 6 m²/s and s = 9 m:

6 m²/s = 2 (9 m) ds/dt

ds/dt = ⅓ m/s
