Find the area of a triangle with a base length of 3 units and a height of 4 units.

svetlana [45]

Answer:

$6$ square units

Step-by-step explanation:

The area of a triangle can be calculated by multiplying the triangle's base by its height, and then dividing the result by $2$ . As an algebraic expression, this would be $\frac{bh}{2}$ , where $b$ is the triangle's base and $h$ is the triangle's height. In this case, we know that $b=3$ and $h=4$ . Therefore, the area of this triangle is $\frac{3*4}{2} =\frac{12}{2} =6$ square units. Hope this helps!

For the function f(x)=3/4x-5 what is f(16)?

GuDViN [60]

$\displaystyle{ f(x)= \frac{3}{4x} -5 } \\\\ f(16)=? \\\\ --------- \\ \\f(16)= \frac{3}{4 \cdot16} -5 = \\ \\ \frac{3}{64} -5^{(64} = \\ \\ \frac{3}{64} - \frac{320}{64}= -\frac{317}{64} =-4.95$
