Answer:

3/10 m^2

Step-by-step explanation:

To calculate area of a triangle we multiply height with base and then divide that by 2

2/5 × 3/2 ÷ 2 = 3/10

The sum of the angles of a triangle is 180°.

The angles you know are 28° and 36°, so you can do this to find ∠B:

∠A + ∠B + ∠C = 180°

or 28° + ∠B + 36° = 180° Add 28 and 36

64° + ∠B = 180° Subtract 64 on both sides

∠B = 116

For which function defined by a

kaheart [24]

Answer:

Option 3

Step-by-step explanation:

If we are given roots of a polynomial, r and q. We can represent the roots as

$(x - r)(x - q)$

The roots here are 0, -3and 4 so the roots are

$x(x - ( - 3)(x - 4)$

Which equal to

$x(x + 3)(x - 4)$

Option 3 is the answer

The expression (1/50)(sqrt(1/50)+sqrt(2/50)+sqrt(3/50)+...+sqrt(50/50) is a Riemann Sum approximation for

alexira [117]

$\dfrac1{50}\left(\sqrt{\dfrac1{50}}+\sqrt{\dfrac2{50}}+\cdots+\sqrt{\dfrac{50}{50}}\right)=\displaystyle\sum_{n=1}^{50}\sqrt{\dfrac n{50}}\frac1{50}$

describes a sum of the areas of 50 rectangles, each of width $\dfrac1{50}$ , and the $n$ th rectangle has height $\sqrt{\dfrac n{50}}$ .

$\sqrt{\dfrac n{50}}$ ranges from a small positive number to 1, which means the integration interval must be $[0,1]$ . The sum is then the right-endpoint Riemann sum of $\sqrt x$ over the interval with $50$ equally spaced subintervals, so

$\displaystyle\sum_{n=1}^{50}\sqrt{\dfrac n{50}}\frac1{50}\approx\int_0^1\sqrt x\,\mathrm dx$

The sum itself evaluates to roughly 0.676, while the exact value of the integral is $\dfrac23\approx0.667$ .
