If there is 1/3 of quantity A for every 4/9 of quantity B, how much of quantity A is there for 2/5 of quantity B?
Answer:
The ratio equivalent to 5/3 is
For example, if we have a ratio 250 to 150, we can simplify it by dividing both numbers by 10 and then by 5 to get 5 to 3: 250 : 150 25 : 15 5:3 . The ratio 5 to 3 is the simplest form of the ratio 250 to 150, and all three ratios are equivalent.

Find an equation of the tangent line to the curve y = 10/(1 + e^-x) at the point (0,5)
Compute the derivative, dy/dx (use the chain rule):
y = 10/(1 + e ⁻ˣ) = 10 (1 + e ⁻ˣ)⁻¹
===> dy/dx = -10 (1 + e ⁻ˣ)⁻² (-e ⁻ˣ) = 10e ⁻ˣ/(1 + e ⁻ˣ)²
Evaluate the derivative for x = 0 to get the slope of the tangent to the curve at (0, 5) :
dy/dx (0) = 10e ⁰/(1 + e ⁰)² = 10/(1 + 1)² = 10/4 = 5/2
Use the point-slope formula to get the equation of the tangent line:
y - 5 = 5/2 (x - 0)
===> y = 5/2 x + 5

evaluate -(2-^6)(2^3)
Answer:
The answer = -512
Step-by-step explanation:
To find -(2-^6)(2^3)
We have that -(2-^6) = {-(-2*-2*-2*-2*-2*-2)}=
-(64) which is -64
For (2^3) = (2*2*2) =8
Therefore -(2-^6)(2^) = (-64)(8)
which is = -512
So therefore -(2-^6)(2^3) = -512

Andre's personal record for the long jump is 16 feet.
Then, he jumps 10% farther.
What is Andre's new personal record for the long jump?
Answer: 17.6
Step-by-step explanation:
16*10/100
160/100
1.6+16
17.6
Answer:
17.6 feet
Step-by-step explanation:
16*10%(or 0.10)= 1.6 feet which is 10% of his 16 foot jump
16+ the 10% increase of 1.6= 17.6 feet as his new record

the graph shown is the solution set for which of the following inequalities
y≤x-1
y≤|x+1|
y≤|x|-1
Answer:
y≤|x+1|
Step-by-step explanation:
If x-a is a factor of the difference of powers of equal odd exponent of the form x[tex]^{n}[/tex]-a[tex]^{n}[/tex] the signs of the second factor are:
A.
All negative
B.
All positive
C.
Alternating +, -, + ...
Answer:
Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Both the first and second signs are negative,
Let α and β are the roots of the ,
then, we know that the relationship between the zeroes and coefficients of quadratic equations:
Since the product of roots is positive.
So, the signs of the factors will be one positive and one negative.
Hence, Option 'D' is correct.
Please help! Suppose f(x)=-8x^7 +8x-6
then f(-x)=________
Answer:
f(-x) = 8x⁷ - 8x - 6Step-by-step explanation:
f(x) = -8x⁷ + 8x - 6
To find f(-x), we'll need to plug in -x instead of x.
f(x) = -8x⁷ + 8x - 6
f(-x) = -8(-x)⁷ + 8(-x) - 6
f(-x) = 8x⁷ - 8x - 6Look for a pattem to find the value of n

Find the exact circumference of the circle. please help?
Answer:
3rd option
Step-by-step explanation:
We first need to find the diameter of the circle.
We know this is a square because all sides are marked by a line so this means they are equal. Let find the diagonal of the square to find all parts of the square.
The diagonal of a square is
[tex]a \sqrt{2} [/tex]
where a is the side lengths of the square.
So this means the diagonal of the square is
[tex]18 \sqrt{2} [/tex]
The diagonal is also the diameter of the main circle. The formula for circumference is
[tex]d\pi[/tex]
where d is the diameter.
So the diameter is
[tex](18 \sqrt{2} )\pi[/tex]
or
[tex]18\pi \sqrt{2} [/tex]
The third option is correct
Todd and Garrett began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Todd took a test in Math and earned a 74.6, and Garrett took a test in English and earned a 68.8. Use the fact that all the students' test grades in the Math class had a mean of 70.6 and a standard deviation of 11.9, and all the students' test grades in English had a mean of 63.7 and a standard deviation of 8.6 to answer the following questions.
Required:
a. Calculate the z-score for Todd's test grade.
b. Calculate the z-score for lan's test grade.
c. Which person did relatively better?
Part A
For Todd's class, we have this given info:
mu = 70.6 = population mean of math scoressigma = 11.9 = population standard deviation of math scoresCompute the z score for x = 74.6
z = (x-mu)/sigma
z = (74.6 - 70.6)/(11.9)
z = 0.34 approximately
Side note: Convention usually has z scores rounded to two decimal places. If your teacher instructs otherwise, then go with those instructions of course.
Answer: 0.34======================================================
Part B
For Garret's English class, we have:
mu = 63.7sigma = 8.6Compute the z score for x = 68.8
z = (x-mu)/sigma
z = (68.8 - 63.7)/(8.6)
z = 0.59 approximately
Answer: 0.59======================================================
Part C
Garret has the higher z score, which means that Garret did relatively better to his classmates compared to Todd's performance (in relation to his classmates). The z score is the distance, in units of standard deviation, the score is from the mean. Positive z values are above the mean, while negative z values are below the mean.
Answer: Garret did relatively betterAbby did 212 sit-ups in 8 minutes.Estimate the number of sit-ups she did in 1 minute
Step-by-step explanation:
212 sit-ups = 8 minutes
1 minutes = 212÷8
1 minutes = 26.5

The ratio of girls to total students in math class is 13 to 20. Using this ratio, how many boys are in math class?
9514 1404 393
Answer:
girls : boys = 13 : 7
7 boys in the math class
Step-by-step explanation:
We assume that the number of boys is the total number of students less the number of girls. In ratio units, that is ...
girls : boys = girls : (total - girls) = 13 : (20 -13)
girls : boys = 13 : 7
There are 7 boys in the math class.
_____
Additional comment
We are only told the ratio, not any actual numbers. In order to answer the question, we must assume a total for the number of students in the class. It is convenient to assume that total is 20. There is nothing in the problem statement to indicate it is not some multiple of 20. The number of boys will be 7/20 of the total number of students in the math class.
