Answer:
f(-5) = 35
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = x² + 10
f(-5) is x = -5
<u>Step 2: Evaluate</u>
- Substitute: f(-5) = (-5)² + 10
- Exponents: f(-5) = 25 + 10
- Add: f(-5) = 35
Answer:
13, 14, 15
Step-by-step explanation:
Let x = age of one of the siblings
Since the age of the siblings are consecutive integers, the age of the next sibling would be x + 1 and the age of the third sibling would be x + 2
x +( x +1) + (x +2) = 42
3x + 3 = 42
collect like terms and solve for x
x = 13
The age of the first sibling is 13
The age of the second sibling is x + 1 = 13 + 1 = 14
The age of the third sibling is x + 2 = 13 + 2 = 15
♥ Lets solve this:
(7*10^5)^2(7*10^5)^2
Starting with 10^5
10*10*10*10*10
We get <span>100000
<span>Now we have 7*100000
Solve for that:
We get </span></span><span>700000
Now we have </span><span>700000^2
Solve for that
We get </span><span>490000000000
and in Scientific notation that is
4.9*10^11</span>
25 + 100i is correct because -5 squared is 25 and the the square root of -100 is 100i or 10i in its simplest form.
