What is the area of triangle ABC ? round to the nearest square unit ?

mash [69]

Answer: 33 square units

Step-by-step explanation:

Given: Sides lengths of the triangle : 16 units, 10 units, 8 units.

Heron's formula:-

$\text{Area of triangle}=\sqrt{s(s-a)(s-b)(s-c)}$ , where s is the semiperter and a,b and c are the side-lengths of the triangle.

Let a=16 , b=10 and c=8

Then,

$s=\dfrac{a+b+c}{2}=\dfrac{16+10+8}{2}=17$

Using Heron's formula:-

$\text{Area of triangle}=\sqrt{17(17-16)(17-10)(17-8)}\\\\\Rightarrow\ \text{Area of triangle}=\sqrt{1071}=32.7261363439\approx33\text{ square units}$

Solve the nonlinear inequality. express the solution using interval notation. (x − 2)(x + 8) < 0 webassign

stepladder [879]

First you find the zeros/x-intercepts using the factors already given in the inequality.

$x = 2$
$x = - 8$

Therefore we make our solution using the interval notation.

$- 8 \leqslant x \leqslant 2$

Which of the following ordered pairs should be tested to determine which

mart [117]

Answer:

C.

If the line doesn't pass through the origin, the easiest point to pick is the origin (0,0). Substitute into your inequality.

y > 5x + 1

0 > 5(0) + 1

0 > 1 which is a false statement.

So, you shade the side of the line on which (0,0) doesn't lie.

If the statement would have be true, you shade the side of the line on which (0,0) lies.
