Answer:

x = 15 units

Step-by-step explanation:

Here, base of triangle = x units & height = 19 units

$Area( \triangle) = \frac{1}{2} \times base \times height \\ \\ 75 = \frac{1}{2} \times x \times 10 \\ \\ 75 = x \times 5 \\ \\ x = \frac{75}{5} \\ \\ \huge \purple{ \boxed{ x = 15 \: units}}$

FORMULA:

Area of ⬜ = (side)²

ANSWER:

We are given with new side 2s + 3.

So, Area = (2s + 3)²

4s² + 9 + 12s
4s² + 12s + 9

The equation of a straight line is 2y = 3x + 4.

saul85 [17]

Answer:

a. 3/2.

b. (0, 2).

Step-by-step explanation:

a. 2y = 3x + 4 Divide through by 2:

y = 3/2 x + 2

Comparing this to the general form y = mx + c where m = the gradient we see that the gradient = 3/2.

b. When the line crosses the y-axis x = 0 so we have the equation:

2y = 3(0) + 4

2y = 4

y = 2.

So the required point is (0, 2).

Step-by-step explanation:

Step 1: you see 45°, which gives you a easy conversion $\frac \pi 4$ ).

Now, $t = 392.7 \mu s = 392.7* 10^{-6} s$ , start replacing.

$V= 50 cos ( 2* 10^3 * 392.7 *10^{-6} -\frac \pi 4) = 50 cos (0.7854 - \frac \pi 4) =\\ 49.999999999999974312306505198184 V$

The slope of the line is -2.

Solution:

Given points are (-3, -7) and (2, -17).

Here $x_1=-3, y_1=-7, x_2=2, y_2=-17$

Slope of the line:

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

$$m=\frac{-17-(-7)}{2-(-3)}$

$$m=\frac{-17+7}{2+3}$

$$m=\frac{-10}{5}$

m = -2

The slope of the line that passes through the pair of points is -2.
