Answer:

Triangle Area = 99.4 yds squared

Trapezoid Area = 57.5 cm squared

Step-by-step explanation:

area = a × b /2

= 7.1 × 14 /2

= 49.7 (for the RAT)

= 49.7 x 2

= 99.4 yd squared

Suppose that the functions g and f are defined as follows.

Sholpan [36]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Given:

$\to g(x)= -3+2x^2 \\\\\to f(x)=9-6x$

Calculating the value of $(\frac{g}{f})(2)$ :

$\to (\frac{g}{f}) (2)= (\frac{g(x)}{f(x)}) \times (2)$

$=\frac{2x^2-3}{9-6x} \times 2\\\\=\frac{2\cdot 2^2-3}{3(3-2\cdot 2)} \\\\=\frac{2\cdot 4-3}{3(-1)}\\\\ =\frac{8-3}{-3}\\\\ =\frac{5}{-3}\\\\ = - \frac{5}{3}\\\\$

x= $- \frac{\sqrt{3}}{2}$ and x= $\frac{\sqrt{3}}{2}$ are not in the domain.

Domain: $x \belong (- \infty, -\frac{\sqrt{3}}{2})\cup (- \frac{\sqrt{3}}{2}, \frac{\sqrt{3}}{2} )\cup (\frac{\sqrt{3}}{2}, \infty)$

Find the surface area of the prism. Enter your answer in the box. A rectangular prism with dimensions 6 meters by 3 meters by 12

e-lub [12.9K]

Given:

Dimensions of a rectangular prism are 6 meters by 3 meters by 12 meters.

To find:

The surface area of the prism.

Solution:

The surface area of a rectangular prism is:

$A=2(lb+bh+hl)$

Where, l is length, b is breadth and h is height.

Putting $l=6,b=3,h=12$ , we get

$A=2(6\times 3+3\times 12+12\times 6)$

$A=2(18+36+72)$

$A=2(126)$

$A=252$

Therefore, the surface area of the prism is 252 square meters.
