Why is the answer for letter b 9?
Answers
Answer:
Take a look at the 'proof' below
Step-by-step explanation:
The graph of the function g(x) is similar to that of the function f(t). The local minimum, local maximum, absolute minimum, maximum etc... of 'x' is always the closest x-intercept of the graph of f(t).
Let's check if this statement is right. The two local minimum(s) of the function f(t) occurs at x = 2, and x = 6. The two local maximum(s) occur at 1/4 and 4. As you can see the maximum / minimum of the function g(x) is always an x-intercept, x = 3, x = 7.
For part (b) the absolute maximum value of the function f(t), is 8. The closest x-intercept is 9, which is our solution.
Step-by-step explanation:
From x=0 to x=1, the function is above the x-axis, so the area is positive.
From x=1 to x=5, the area above the x-axis is greater than the area below the x-axis, so the net area is positive.
From x=5 to x=9, the area above the x-axis is greater than the area below the x-axis, so the net area is positive.
Since the area increases in each interval, the area is a maximum at x=9.
In a volcano, erupting lava flows continuously through a tube system about 13 kilometers to the sea. Assume a lava flow speed of 0.5 kilometer per hour and calculate how long it takes to reach the sea.
Answers
Answer:
26 hours
Step-by-step explanation:
speed = distance/time
s = d/t
st = d
t = d/s
t = (13 km)/(0.5 km/h)
t = 26 h
Answer: 26 hours

Write a numerical expression for the verbal phrase. The quotient of 81 and 3.
A. 3÷81
B. 27
C. 81÷3
D.81×3
Answers
Answer:
C. 81÷3
Step-by-step explanation:
We want to write a numerical expression for the phrase: "the quotient of 81 and 3"
Quotient indicates division, so we must divide 81 by 3.
81÷3
This can be further simplified, but the questions asks for a numerical expression. This is defined as an expression with numbers and at least one operation. So, B is correct, because 81 divided by 3 is 27, but it is not a numerical expression.
Therefore, the best answer choice is C. 81÷3
The sale price of a new refrigerator is $648 and sales tax is figured at 0.10 times the price. What is the total amount paid for the refrigerator?
Answers
Answer:
$712.80
Step-by-step explanation:
648×0.10=64.8
648+64.8=712.8
The total amount paid for the refrigerator is $712.8.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Sale price = $648
Sales tax = 0.10 times the price
The total amount paid.
= 648 + 0.10 x 648
= 648 + 64.8
= 712.8
Thus,
The total amount paid is $712.8.

An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression when simplified is equal to 2.3684.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
As per the PEMDAS, we will first solve the parenthesis. Since the round parenthesis is solved first, therefore, we can write,
90 ÷ [10 + ( 32 − 4 )]
= 90 ÷ [10 + (28)]
= 90 ÷ [10 + 28]
Solving the next parenthesis, therefore, the square brackets,
= 90 ÷ [10 + 28]
= 90 ÷ 38
At last, we will solve the division, therefore, we can write,
= 90 ÷ 38
= 2.3684
Hence, the value of the expression when simplified is equal to 2.3684.

h(x)= 4(x + 6)
Let x=4
h(4)= 4(4 + 6)

To find h(4), substitute 4 for x. Thus:
[tex]h(4)=4(4+6)[/tex]
Add within the parentheses:

Multiply:
[tex]h(4)=40[/tex]
The answer is D.

Solve the formula 2x+3y=12 for y.
Answers
Answer:
y=4 - [tex]\frac{2x}{3}[/tex]
Step-by-step explanation:
The value of y for 2x + 3y = 12 is (12 - 2x) / 3.
Given,
2x + 3y = 12
We will solve for y.
How to solve an equation for a variable?We will keep the like terms on one side of the equation and solve for the required variable.
Example: x + 2x + y = 3 + 2y
Solve for y:
x + 2x + y = 3 + 2y
3x = 3 + 2y - y
3x - 3 = y
3(x - 1) = y
y = 3(x - 1) is our answer.
Solve 2x + 3y = 12 for y.
We have,
2x + 3y = 12
Keep y on one side of the equation.
3y = 12 - 2x
Divide both sides by 3.
y = (12 - 2x) / 3
Thus the value of y for 2x + 3y = 12 is (12 - 2x) / 3.
