If y varies directly as x and as the square of z, and y =25/9 when x=5 and z=1, find y when x =1 and z=4
Answer:
y= 80/9
Step-by-step explanation:
Given
" y varies directly as x" and "as the square of z" so y = x* z²* some number
if y =25/9 when x= 5, z= 1 and y = x*z²* some number
then 25/9 = 5 * 1² * some number
5*(5/9) = 5 * some number
therefore y = x* z²* (5/9)
y= ? when x=1 , z= 4
y = x * z² * (5/9)
y = 1 * 4² * (5/9)
y = 16*5 / 9
y = 80/9
After 12 years I shall be three times as old as I was 34years ago. Determine my present age
Answer:
the 34 yrs Is wrong it will be 4yrs only.
Step-by-step explanation:
Let my present age=x years
After 12 years my age=x+12 years
4 years ago my age =x−4 years
According to the question,
x+12=3(x−4)
⇒x+12=3x−12
⇒3x−x=12+12
⇒2x=24
or x= 24/2 =12 years.
∴ my present age is 12 years.
hope this helps you.

the GCF of 30m^4 and 36m^6 is 6m^?
the missing exponent is ____
9514 1404 393
Answer:
4
Step-by-step explanation:
The exponents of m in the two terms are 4 and 6. The exponent of the common factor can be no greater than the smallest of these. (It is the smallest of these.)
GCF(30m^4, 36m^6) = 6m^4 . . . . exponent is 4
What single decimal multiplier would you use to decrease by 2% followed by a 7% decrease?
9514 1404 393
Answer:
0.9114
Step-by-step explanation:
That multiplier would be ...
(1 -2%)×(1 -7%)
= (1 -0.02)(1 -0.07)
= 0.98×0.93 = 0.9114
Please help me!!
The formula to find the kinetic energy of an object measured in joules,E, is E=1/2mv2, where m represents the mass of the object in kilograms and v represents the velocity (or speed) of the object in meters per second. What is the equation to find m in terms of E and v ?
Thank you very much!!

Answer:
it will look like this 4(a+3)-2/3
Step-by-step explanation:
look since the equation "a+3" replaced for the place of "x" in f(x), you replace it on the equation "4x- 2/3" and just solve

Calculus, second derivative. Please help! Show work, if possible please. Thanks! :)
Answer:
y''=sec^3(x)*csc(x)+sec^2(x)*tan(x)-2cot(x)*csc(x)*sec(x)*tan(x)+cot^2(x)*csc(x)*sec(x)+csc^3(x)*sec(x)
Step-by-step explanation:
we are given y= csc x sec x
We use the rule for multiplying derivatives and the knowledge that the derivative of csc is -csc*cot and the derivative of sec is sec*tan to get
csc(x)*sec(x)*tan(x)+sec(x)*-csc(x)*cot(x)
which simplifies to
csc(x)*sec(x)*tan(x)-sec(x)*csc(x)*cot(x)
Using the same rules again (in tedium so they are not listed but can be inferred) we find the second derivative is
sec^3(x)*csc(x)+sec^2(x)*tan(x)-2cot(x)*csc(x)*sec(x)*tan(x)+cot^2(x)*csc(x)*sec(x)+csc^3(x)*sec(x)

How many electrons in an atom can share the quantum numbers n = 2, l = 1, ml = −1?
1
2
3
6
It's not B
Answer:
Answer is: two electrons.
n - principal quantum number, indicating relative overall energy of each orbital, n=1,2,3,...
l - angular momentum quantum number, shape of the orbital, l = 0,1,...,n−1.
l =1 for the p orbitals.
ml - magnetic quantum number, ml = 0,±1,...,±l.
This is 2px orbital, in every orbital there is two electrons with different spin.

What is a two-way frequency table?A two-way frequency table is a way of organizing and displaying data that shows the frequency of occurrences of two categorical variables.
In such a table, the rows represent one variable, the columns represent the other variable, and the cells show the number (or frequency) of times that each combination of categories occurs.
We have,
A two-way frequency table shows how many times each combination of two categorical variables occurs.
In the table, the rows represent the "play an instrument" variable, the columns represent the "are in band" variable, and the totals are shown at the end of each row and column.
The entries in the table represent the frequency, or the number of students who belong to each combination of categories.
In this case, the two variables are "play an instrument" and "are in band". Based on the given information, we can create the following table:
Thus,
The table that shows these data correctly entered in a two-way frequency table is:
In Band Not in Band Total
Play 15 10 25
Do Not Play 5 20 25
Total 20 30 50
