Answer:

Step-by-step explanation:

First we have to find out area of the base

$s = \frac{a + b + c}{2}$

$= \frac{5 + 12 + 13}{2}$

$= \frac{30}{2}$

$= 15$

Area of base = $\sqrt{s(s - a)(s - b)(s - c)}$

$= \sqrt{15(15 - 5)(15 - 12)(15 - 13)}$

$= \sqrt{15 \times 10 \times 3 \times 2}$

$= \sqrt{5 \times 3 \times 5 \times 2 \times 3 \times 2}$

$= 2 \times 3 \times 5$

$= 30 \: {cm}^{2}$

Now, let's find the volume of triangular pyramid

$= \frac{1}{3} \times a \times h$

$= \frac{1}{3} \times 30 \times 12$

$= 120 \:$ cm³

Hope this helps..

best regards!!

Answer:

$1000 ; 500 ; 1000 ; y = 500x + 1000

Step-by-step explanation:

From the graph, the initial deposit which started the savings account is $1000 ; this is the value on the y - intercept, the value in the account at time or period = 0.

The slope :

x1 = 0 ; y1 = 1000

x2 = 6 ; y2 = 4000

Slope = Rise / Run

Rise = y2 - y1 = 4000 - 1000 = 3000

Run = x2 - x1 = 6 - 0 = 6

Hence,

Slope = 3000 / 6

Slope = 500

y - intercept = 1000 (from. Graph)

Equation in slope intercept form:

General form : y = mx + c

m = slope ; c = intercept

Equation is written as ;

y = 500x + 1000
