Because the graph is starting high and going down, your answer is c- exponential decay
The answer is 74.6 I did that question
Answer:
x = 1
Step-by-step explanation:
For this problem, we are simply solving for x, and analyzing the results of the two students. First let's solve for x ourselves:
5 ( x + 3 ) = 20
5 ( x + 3 ) * ( 1 / 5 ) = 20 * ( 1 / 5)
x + 3 = 4
x + 3 + -3 = 4 + -3
x = 1
So we know the solution for this equation is x = 1.
Now let's look at the solutions of the two students. Alex's "divide first" way is correct since it follows the proper order of operations. The order of operations are simply a way in which to simplify problems correctly. Here is the order of things to handle first:
Parenthesis --> Exponents --> Multiplication (Division) --> Addition (Subtraction)
Looking at Morgan's "subtract first" way, we know that he has violated the order of operations. For this specific problem, the distributive property of multiplication is ignored in Morgan's approach, resulting in an incorrect answer.
I hope this helps.
Cheers.
Answer:
84
Step-by-step explanation:
The bases of a trapezoid have lengths 10 and 18. If the height of the trapezoid is 6, what is the area of the trapezoid
The area of a trapezoid is given as:
1/2(b1 + b) × h
Where:
b1 = Base 1 = 10
b2= Base 2 = 18
h = Height = 6
Therefore, the area of a trapezoid =
1/2 (10 + 18) × 6
= 28/2 × 6
= 84
Therefore, the area of the trapezoid = 84
Answer: 2 2/5
<u>Turn -1 3/5 into an Improper Fraction</u>
Multiply -1×5 and get -5. Now add 3 and get -8.
-1 3/5 = -8/5
<u>Do Keep Change Flip</u>
Keep: -8/5
Change: ÷ into ×
Flip: -2/3 into -3/2
<u>Multiply</u>
-8/5×-3/2=12/5
<u>Simplify</u>
12/5 = 2 2/5
