What does the expression (8x)2 represent

Answers

Answer 1

Answer:

Option D is correct.

We have an expression that is used to calculate the area of a square - $s^(2)$ , where s is the side of the square.

We have to estimate the value of the expression $(8x)^(2)$

What is the area and perimeter of a square of side 'a' ?

The area of a square is - Area = $a^(2)$ and the perimeter is - P = 4a.

In the question, we have to estimate the value of the expression $(8x)^(2)$ .

Let f(x) = $(8x)^(2)$

The expression given to us is $s^(2)$ .

Let f(s) = $s^(2)$

Compare f(s) and f(x), you will get -

s = 8x

Hence, the expression $(8x)^(2)$ represents the area of square with side length of 8x.

Hence, Option D is correct.

Answer:

8.5 or 4.25 i think pretty sure its 8.5 tho

Step-by-step explanation:

Y+z+ 2; use y=-6, and z = 5

Answers

When y = -6 and z = 5, the value of the expression y + z + 2 is 1.

To calculate the expression y + z + 2 when y = -6 and z = 5, you simply substitute these values into the expression and perform the arithmetic operations:

y + z + 2 = (-6) + (5) + 2

Now, perform the addition:

(-6) + (5) + 2 = -1 + 2 = 1

So, when y = -6 and z = 5, the value of the expression y + z + 2 is 1.

A. Use your calculator to approximate ∫^ b_0 e^-0.00001x dx for b=10, 50, 100 and 1000.b. Based on your answers to part a, does ∫^[infinity]_0 e^-0.00001 dx appear to be convergent or divergent?
c. To what value does the integral actually converge?

Answers

Answer:

Step-by-step explanation:

We are to integrate the function

$e^-0.00001x$ from 0 to b for different ascending values of x.

$\int e^-0.00001x = -10^5 e^-0.00001x$

Now we substitute the limits

When b =10

I = integral value = $-10^5 e^-0.00001*10$

b =50, I = $-10^5(e^-0.00001*50-1)$

b =100, I = $-10^5( e^-0.00001*100-1)$

b =1000 I= $-10^5 (e^-0.00001*1000-1)$

b) As b increases exponent increases in negative, or denominator increases hence when b becomes large this will be a decreasing sequence hence converges

c) Converges to $-10^5 (0-1)$ =10^5
