The ratio of the radius of the small sphere with a volume of 36π cubic centimeters to the radius of the large sphere having a volume of 288π cubic centimeters is 1/2.
Given two spheres having volumes of 36π cubic centimeters and 288π cubic centimeters, solve for the radius of each sphere using the formula for the volume of sphere given by:
V = 4/3πr^3
smaller sphere :
36π cubic centimeters = 4/3πr^3
r^3 = 27
r = 3 centimeters
larger sphere :
288π cubic centimeters = 4/3πr^3
r^3 = 216
r = 6 centimeters
Getting the ratio of the radius of the small sphere to the radius of the large sphere:
ratio = radius of the small sphere / radius of the large sphere
ratio = 3 centimeters / 6 centimeters
ratio = 1/2

CCSS ARGUMENTS Write a coordinate proof for each statement.The three segments joining the midpoints of the sides of an isosceles triangle form another isosceles triangle.
The triangle formed by joining the midpoint of an isosceles triangle is also an isosceles triangle.
What is an isosceles triangle?An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.
An isosceles triangle XYZ is been made as shown below. Now, for the ΔXYZ, the midpoints of the line segment XY, YZ, and ZX are A, B, and C, respectively.
Further, the length of the sides of the ΔABC can be written as,
AB = √[(x₂-x₁)² + (y₂-y₁)² ]
= √[(3 - 1)² + (1 - 1)²]
= √4
= 2
BC = √[(x₂-x₁)² + (y₂-y₁)² ]
= √[(3 - 2)² + (1 - 0)²]
= √2
AC = √[(x₂-x₁)² + (y₂-y₁)² ]
= √[(1 - 2)² + (1 - 0)²]
= √2
Since, the length of the two sides is the same, while the length of the third side is different, thus, the triangle formed by joining the midpoint of an isosceles triangle is also an isosceles triangle.

Connor has a biased dice. The
probability of it landing on a
three is 0.8. Connor is going to
throw the dice 120 times.
Work out an estimate for the
number of times the dice will
land on a three.
Step-by-step explanation:
120×0.8
120/10)×8
=12×8
=96
The estimated number of times the dice will land on a three in 120 throws is 96 times.
We have,
To estimate the number of times the biased dice will land on a three, we can use the probability of getting a three in a single throw and multiply it by the total number of throws.
Probability of landing on a three in a single throw = 0.8
Total number of throws = 120
Estimated number of times the dice will land on a three
= Probability of landing on a three × Total number of throws
Estimated number of times = 0.8 × 120
Estimated number of times = 96
So, based on the biased dice with a probability of 0.8 for landing on a three, the estimated number of times the dice will land on a three in 120 throws is 96 times.
Thus,
The estimated number of times the dice will land on a three in 120 throws is 96 times.

The standard form of the equation of circle is given by

F = -16
If D = -2h and D = 0, then

represent this monthly cost would be:
C = 29.95 + 0.035x, where C represents the monthly cost and x represents the number of minutes used.
How many minutes were used during a month if the cost amounted to $43.53 ?
O 506 minutes
O 426 minutes
O 388 minutes
438 minutes
Answer:
c) 388 minutes
Step-by-step explanation:
Given equation,
→ C = 29.95 + 0.035x
Then the call duration will be,
→ C = 29.95 + 0.035x
→ 43.53 = 29.95 + 0.035x
→ 0.035x = 43.53 - 29.95
→ x = 13.58/0.035
→ [ x = 388 ]
Hence, option (c) is correct.
Which expression is equivalent to (3x^−4y^5) ^−2?
A: -9^8y^10
B: x^8/ 9y^10
C: -9x^8/ y^10
D: 1/ 9x^8y^10
(x's are variables not multiplication) (dashes resemble fractions) (^ resembles powers)
The equivalent expression to the given one is x^8/(9*y^10)
So the correct option is B.
Which expression is equivalent to (3x^−4y^5) ^−2?Here we just need to operate with the exponent properties that we know and love.
Remember that:
(a^n)^m = a^(n*m)
Then if we apply that to our case we will get:
(3x^−4y^5) ^−2 = (3^(-2)*x^(-4*-2)*y^(5*-2))
= (3^(-2)*x^8*y^(-10)
Now remember that negative exponents just "move" the number to the denominator position, this means that:
3^-2 = 1/3^2 = 1/9
Then we can rewrite our expression as:
(3^(-2)*x^8*y^(-10) = x^8/(9*y^10)
That is the equivalent expression to the given one.
The correct option is B.

What is termed as logarithmic functions?A logarithmic term is a number expressed in logarithmic form. Some other name for it is a log term.
A number could also be the sum of two or more numbers. As a result, a term can be the product of two or even more quantities, at least one of which should be in logarithmic form. These same terms are recognised as log terms in such cases.A quantity can also be described as the variation between two quantities. However, if a term contains a quotient of quantities, or if at least one of the amounts can also be conveyed in log form, the term is referred to as a log term.Consider some formulas used in log.
Quotient Rule: ㏒(A/B) = ㏒A - ㏒BProduct Rule : ㏒A + ㏒B = ㏒(AB)Power Rule: n㏒A = ㏒AⁿBase Rule = ㏒ₐb = ㏒ₓb/㏒ₓaExponent Rule = e∧lnx = xNow, as per the given question,
The function is written as;
P = 42e∧(-0.005t).
The value of the power P is mentioned in the question; (P = 35 watt).
Thus, substitute the value of the P in teh equation;
35 = 42e∧(-0.005t).
Now, divide both sides by 42.
0.8333 = e∧(-0.005t)
Taking natural log on both side;
㏒0.8333 = ㏒e∧(-0.005t)
㏒0.8333 = -0.005t
Solve the value of the log by using calculator,
-0.182 = -0.005t
