A quantity y varies inversely with the square of x. If y=8 when x=3, find y when x is 4
A. 3/2
B. 7/3
C. 9/2
D. 5/3
Answer:
look at the explanation
Step-by-step explanation:
In order to solve this, we'll set up a proportion.
Since y is inversely related to the square of x, therefore:
y=4/63 ----->9 (square of x)
y=?
25 (square of x)
According to the inverse relation:
y=4/63------->25
y=? --------
-->9 and y=4/175

Suppose you write the numbers 1 to 10 on separate index cards. You randomly choose one card, place it back in the set, and then randomly choose another card. What is the probability that the first card you choose is the number 1 or the second card you choose is the number 2?.
Answer:
1/100
Step-by-step explanation:
From 1 to 10 there are 10 numbers, so the fraction would be:
# / 10
Since you are putting the cards back into the deck, the denominator will never change.
The chances of getting " 1 " are 1 / 10.
And the chances of getting " 2 " are also 1 / 10
To find the odds of getting one-after-the-other, you multiply these 2 chances.
( 1 / 10 ) x ( 1 / 10 ) = ( 1 / 100 )
There is a 1 / 100 chance that you will draw 1, then 2 if you put the cards back after drawing.

If Jacob lives until the end of the term of his policy, the total amount he would have paid in premiums overall is $50,850.
How much would he have paid in premiums?
Total premium payment = (face value / average premium rate) x number of years x premium
($500,000 / 1000) x $6.78 x 15 = $50,850

A quantity with an initial value of 870 decays continuously at a rate of 0.75% per day.
what is the value of the quantity after 10 weeks, to the nearest hundredth?
The function of the exponential decay will be y = 870(0.75)ˣ. Then the value of the quantity after 10 weeks will be 49.
What is exponential growth or decay function?Consider the function:
y = a(1 ± r)ˣ
where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction.
If there is a negative sign, then there is exponential decay happening by r fraction.
A quantity with an initial value of 870 decays continuously at a rate of 0.75% per day.
Then the function is given as
y = 870(0.75)ˣ
Then the value of the quantity after 10 weeks will be
y = 870(0.75)¹⁰
y = 870 (0.0563)
y = 48.99
y ≅ 49

What is the exact value of the other root?
The exact value of the other root to the quadratic equation is [tex]x = -2 - \sqrt 6[/tex]
How to express the solution?One of the root is given as:
[tex]x = -2 - \sqrt 6[/tex]
As a general rule, the solution to a quadratic equation is represented by:
[tex]x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
This means that the actual root of the given root is:
[tex]x = -2 \pm \sqrt 6[/tex]
Split the equation
[tex]x = -2 - \sqrt 6[/tex] and [tex]x = -2 + \sqrt 6[/tex]
Hence, the exact value of the other root to the quadratic equation is [tex]x = -2 - \sqrt 6[/tex]

Answer:
Step-by-step explanation:
Answer: 1/5 of the total distance to his grandmothers house was traveled on Sunday
The total distance to to his grandmothers house is assumed to be 1
Marks family traveled 7/10 of the distance to his grandmothers house on Saturday. The remaining distance would

Answer: 12.5
Step-by-step explanation:
12.5 is the length of BC.
Here, we have,
given that,
In the diagram shown below, AC is tangent to circle o at A and to circle Pat C, OP intersects AC at B, OA = 5, AB = 5, and PC = 10.
now, we know that,
∠OAB and ∠BCP are right angles, because of the tangents.
and, ∠OBA ≅ ∠CBP (vertical angles)
thus, we get,
ΔAOB ≅ ΔCBP, by AA rule.
so, we can set up the proportion:
10/4 = x/5
or, x = 12.5
Hence, 12.5 is the length of BC.
