Question

−15+4/5(15e−10)−10e .(1 point)

Answer 1

[AI-generated answer — Bot GPT 3.5]

To solve this expression, we need to follow the order of operations (PEMDAS/BODMAS).

First, we need to simplify anything inside parentheses or brackets. In this case, we have (15e−10).

Next, we need to perform any exponentiation. There are no exponents in this expression.

Then, we need to perform any multiplication or division from left to right. In this case, we have 4/5(15e−10), which can be rewritten as (4/5)*(15e−10).

Following the same rule, we have -15 + (4/5)*(15e−10) − 10e.

Finally, we perform the addition and subtraction from left to right.

Let's plug in a random value for e and calculate the expression:

e = 2

-15 + (4/5)*(15e−10) − 10e
-15 + (4/5)*(15*2−10) − 10*2
-15 + (4/5)*(20) − 20
-15 + (80/5) − 20
-15 + 16 − 20
-15 + (16-20)
-15 + (-4)
-19

So, the value of the expression is -19.

Answer 2

sorry the answers are the following

2e−23
2 e minus 23

−2e−23
negative 2 e minus 23

−2e+23
negative 2 e plus 23

2e+23

Apologies for the confusion. Let's go through the given expressions one by one and evaluate them.

1) -15 + (4/5)(15e−10) − 10e:
To evaluate this expression, we'll need the value of "e" given. Let's assume e = 2.

Plugging in the value of e:
-15 + (4/5)(15*2−10) − 10*2
-15 + (4/5)(30-10) - 20
-15 + (4/5)(20) - 20
-15 + (80/5) - 20
-15 + 16 - 20
-19

So, -15 + (4/5)(15e−10) − 10e evaluates to -19 when e = 2.

2) 2e−23:
Again, to evaluate this expression, we need the value of "e". Assuming e = 2:

2e−23 = 2*2 − 23 = 4 - 23 = -19

So, 2e−23 evaluates to -19 when e = 2.

3) -2e−23:
Assuming e = 2:

-2e−23 = -2*2 − 23 = -4 - 23 = -27

So, -2e−23 evaluates to -27 when e = 2.

4) -2e+23:
If we assume e = 2:

-2e+23 = -2*2 + 23 = -4 + 23 = 19

So, -2e+23 evaluates to 19 when e = 2.

Note: It is important to have the value of "e" to accurately evaluate these expressions.

Answer 6

Factor 48y+36z using the GCF.(1 point)

Answer 7

[AI-generated answer — Bot GPT 3.5]

To factor 48y + 36z using the greatest common factor (GCF), we need to find the highest common factor of the coefficients 48 and 36, as well as the common variable term.

Step 1: Find the GCF of 48 and 36:
48 = 2^4 * 3
36 = 2^2 * 3^2

The GCF of 48 and 36 is 2^2 * 3 = 12.

Step 2: Determine the GCF of the variable terms:
The GCF of "y" and "z" is 1 since they do not have any common factors other than 1.

Step 3: Combine the GCF of the coefficients with the GCF of the variable terms:
The GCF of the coefficients is 12, and the GCF of the variables is 1.

Therefore, we can factor 48y + 36z as:
12(4y + 3z)

So, 48y + 36z can be factored as 12(4y + 3z) using the GCF.

Answer 10

[AI-generated answer — Explain Bot]

To solve the expression −15 + (4/5)(15e−10) − 10e, we can follow the order of operations.

Step 1: Start by evaluating the exponential term 15e^-10. Use the exponent property that states e^a · e^b = e^(a + b). So, 15e^-10 can be rewritten as 15 · e^-10, where e^-10 is approximately 0.00004539992 (rounded to eight decimal places).

Step 2: Now, multiply 4/5 by 15 · e^-10. Ergo, (4/5) · 15 · e^-10 equals (60/5) · e^-10 or 12 · e^-10.

Step 3: Evaluate the last term, which is simply -10e.

Step 4: Substitute the computed values back into the expression −15 + (4/5)(15e−10) − 10e, so it becomes:

-15 + 12 · e^-10 - 10e

Step 5: Combine like terms.

-15 - 10e + 12 · e^-10

This is the simplified form of the original expression.
