1. Determine the lateral and total surface area

ANTONII [103]

The areas of the square pyramid are the amount of space on it

The lateral surface area is 307.2 square cm
The total surface area is 451.2 square cm

<h3>How to determine the lateral surface area?</h3>

The given parameters are:

Base (b) = 12 cm

Slant height (l) = 12.8 cm

The lateral surface area is calculated using:

L = 2bl

So, we have:

L = 2 * 12 * 12.8

Evaluate the product

L = 307.2

<h3>How to determine the total surface area?</h3>

This is calculated using:

T = L + b^2

So, we have:

T = 307.2 + 12^2

Evaluate

T = 451.2

Hence, the total surface area is 451.2 square cm

The velocity of an automobile starting from rest is given by the equation below, where v is measured in feet per second and t is

podryga [215]

Answer:

(a) $0.408m/sec^2$

(b) $0.134m/sec^2$

(c) $0.039m/sec^2$

Step-by-step explanation:

We have given velocity as function of t $v(t)=\frac{85t}{(8t+14)}$

Acceleration is equation rate if change of velocity with respect to time

So $a=\frac{dv}{dt}=\frac{(8t+14)85-85t\times 8}{(8t+14)^2}$

(a) Acceleration at t = 5 sec

$a=\frac{(8\times 5+14)85-85\times 5\times 8}{(8\times 5+14)^2}=0.408m/sec^2$

(b) Acceleration at t = 10 sec

$a=\frac{(8\times 10+14)85-85\times 10\times 8}{(8\times 10+14)^2}=0.134m/sec^2$

(c) Acceleration at t = 20 sec

$a=\frac{(8\times 20+14)85-85\times 20\times 8}{(8\times 20+14)^2}=0.039m/sec^2$

Find the value of x, y, and z.

tankabanditka [31]

Answer:

Step-by-step explanation:

x² + 25 = 36 ⇒ <em>x</em> = √11 ≈ <em>3.3 </em>

5y = 11 ⇒ <em>y </em>= 11 ÷ 5 <em>= 2.2</em>

z = y + 5 ⇒ <em>z = 7.2</em>
