Find the acceleration. I don’t understand this, please help
Answer:
At t = 9, Whitney's acceleration will be -0.2 miles per minute.
Step-by-step explanation:
Remember that the acceleration is the derivative of velocity.
Since we want to find Whitney's acceleration at t = 9 and we are given the velocity function, we can simply find the derivative of the point at t = 9. In other words, a(9) = v'(9).
For the interval (7, 11), we simply have a line. So Whitney's acceleration at t = 9 will be equivalent to the slope of that line.
We have the two points (7, 0.8) and (11, 0). So, the slope between them is:
[tex]\displaystyle m=\frac{0-0.8}{11-7}=\frac{-0.8}{4}=-\frac{1}{5}[/tex]
So, a(t) = v'(t) = -0.2 ∀t ∈ {t | 7 < t < 11}. Then at t = 9, Whitney's acceleration will be -0.2 miles per minute.
There are 74 milligrams of cholesterol in a 3.9 oz serving of lobster how much cholesterol is in 8 ounces of lobster
9514 1404 393
Answer:
151.8 mg
Step-by-step explanation:
Assuming the cholesterol content (c) is proportional to the serving size, we have ...
c/8 = 74/3.9
c = 8(74/3.9) ≈ 151.8 . . . . mg of cholesterol

Adam thinks of a number.
He multiplies it by 8, adds 6 and then divides it by 2.
He ends up with 131.
What was the number he started with?
The number Adam started with is 32.He ends up with 131.
Let's denote the number Adam started with as "x." After multiplying by 8, we have 8x.
He adds 6 to the result.
The expression becomes 8x + 6.
He divides the result by 2.
The expression becomes (8x + 6) / 2.
The final result is 131.
Setting up the equation:
(8x + 6) / 2 = 131
To find x, we can solve this equation.
Multiplying both sides by 2:
8x + 6 = 262
Subtracting 6 from both sides:
8x = 256
Dividing both sides by 8:
x = 32
Therefore, the number Adam started with is 32.

7. Construct Arguments Harriet says that it
is not possible to draw a quadrilateral that
is not a trapezoid and not a parallelogram.
Is Harriet correct? Explain why or why not.
Answer:
She is not correct because trapezoid and parallelogram are not the only type of Quadrilaterals.
Step-by-step explanation:
Quadrilaterals are basically 4 sided shapes. Examples include Square, rectangle, rhombus, parallelogram, trapezoid, kite e.t.c.
Now, Harriet is saying that it
is not possible to draw a quadrilateral that is not a trapezoid and not a parallelogram. This statement is wrong because aside trapezoid and parallelogram, I have listed other types of Quadrilaterals above that can be drawn.

convert 2 miles to centimeters.
express your answer in scientific notation
Answer:
To convert miles to cm, multiply the mile value by 160934.4. For example, to find out how many centimeters there are in 2 miles, multiply 2 by 160934.4, that makes 321868.8 cm in 2 miles.
multiply 2 by 160934.4, which is
321868.8 cm in 2 miles.
How do you change miles into centimeters?
To convert a mile to a centimeter, multiply the length by the conversion ratio. The length in centimeters is equal to the miles multiplied by 160,934.4.
The distance in km is equal to the distance in miles multiplied by 1.609344. Since 1 mile is equal to 1.609344 km, that's the conversion ratio used in the formula.

11. Albert has 12 more 10 cent coins than 20-cent
coins. The total value of all his coins is $5.40. Find
the total number of coins he has.
Step-by-step explanation:
Let x be the number of 10 cent coins
Let y be the number of 20 cent coins
given
[tex]x = y + 12 \\ x - y = 12[/tex]
as equation 1
and
[tex]0.1x + 0.2y = 5.4[/tex]
as equation 2.
Now we will use elimination method to solve simultaneous equations.
Now we multiply equation 1 by 0.2 to eliminate y and solve for x first.
[tex]0.2 \times x - 0.2 \times y = 12 \times 0.2 \\ 0.2x - 0.2y = 2.4[/tex]
Let this new equation be equation 3.
Now use equation 2 + equation 3.
[tex]0.1x + 0.2x + (0.2y + ( - 0.2y)) = 5.4 + 2.4 \\ 0.3x = 7.8 \\ x = 7.8 \div 0.3 \\ = 26[/tex]
Substitute x into equation 1,
[tex]x = y + 12 \\ y + 12 = x \\ y = x - 12 \\ = 26 - 12 \\ = 14[/tex]
Therefore total number of coins = x + y = 26 + 14 = 40
Answer:
in total he has 62 cents

Which values are solutions to the inequality below? Check all that apply.
x² < 144
What are the two answers for this and how do I complete this problem?
9514 1404 393
Answer:
-12 < x < 12
Step-by-step explanation:
It helps to think about what this looks like on a graph.
y = x² describes a parabola that has its vertex at the origin and opens upward. You know that 12² = 144, so the value of x² will exceed 144 when the value of x is more than 12. You also know the parabola is symmetric about the y-axis, so the same will be true for values of x less than -12.
The one solution to the inequality is ...
-12 < x < 12
__
You can also go at this slightly differently--a way you might want to use for more complicated quadratic inequalities. Put the inequality in standard form, and factor it.
x² -144 < 0
(x +12)(x -12) < 0
Note that these factors are zero for x = -12 and for x = 12. The solution is the set of values of x where the sign of the product is negative.
The sign of the product of two numbers will be negative when one of them is negative and the other is positive. Since the zeros of this product are -12 and +12, the sign of the product will be different in the intervals (-∞, -12), (-12, 12), and (12, ∞). In the left-most of these intervals, both factors are negative, so the product is positive and the interval is not part of the solution set.
For the middle of these intervals, (-12, 12), the sign of (x+12) is positive and the sign of (x-12) is negative. The product will have a negative sign, so this interval is part of the solution set.
For the rightmost interval (12, ∞), both factors have positive signs, so the product is positive and the interval is not in the solution set.
Based on the analysis of the signs of the factors, we realize the solution to the inequality is the interval (-12, 12), or -12 < x < 12.
_____
The wording of your question suggests you are given a list of numbers and asked to identify those that satisfy the inequality. We don't see that list, so we can only tell you the set of numbers the solutions must be in.
Note that -12 or +12 are not solutions to this.
