Given the volume of the initial solid, V1 = 36 cubic units. Let's assume the dilated scale factor is K and the volume of the dilated solid is V2 = 4 cubic units.
We need to find the value of K using the given data. Relation between volumes of two similar solids: Let the scale factor between the corresponding sides of the two similar solids be k, then the ratio of their volumes is given [tex]by:$$\frac{Volume \ of \ Dilated \ Solid}{Volume \ of \ Initial \ Solid} = k^3$$Let's apply this formula to solve this problem. Substitute V1 = 36 cubic units, and V2 = 4 cubic units.$$k^3 = \frac{V2}{V1}$$On substituting the given values, we get;$$k^3 = \frac{4}{36}$$$$k^3 = \frac{1}{9}$$$$\sqrt[3]{k^3} = \sqrt[3]{\frac{1}{9}}$$$$k = \frac{1}{3}$$Therefore, the value of K is 1/3.[/tex]

What is the y-intercept of a line that passes through the points (3, -3.8) and (5, -3)? (1 point)
Enter the solution in the box below.
Answer:
Step-by-step explanation:
We can solve this by either identifying the equation or by graphing. We'll try both.
Find the Equation
The slope of the line can be determined from the Rise/Run of the 2 given points:
Going from ((3,-3.8) to (5,-3):
Rise = (-3 - (-3.8) = 0.8
Run = (5 - 3) = 2
Slope = 0.8/2 or 0.4
The equation for this line is y = 0.4x + b, where b is the y-intercept.
Enter either point to find b:
y = 0.4x + b
-3 = 0.4*(5) + b for point (5,-3)
-3 = 2+b
b = -5
The equation is y = 0.4x - 5
The y=intercept is -5 (the value of b)
Graphing
See the attached graph. Mark the two points and then draw a straight line between them. The point at which the line crosses the y axis is the y-intercept (0,

(c) P(2 or more heads) = P(X ≥ 2) = 1 - P(X ≤ 1) = 1 - (1!/1^1)(1/4) - (0!/0^0)(1/4)^0 = 0.9375

What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Suppose that the inequality is x - 3 < 0.
x - 3 < 0
Adding 3 on both sides of the equation,
x - 3 + 3 < 0 + 3
x < 3
x< 3 is the solution of the expression x - 3 < 0.
Consider the inequality x + 3 < 0.
x + 3 < 0
Subtracting 3 from both sides,
x + 3 - 3 < 0 - 3
x < -3

what is the answer for this math question -q/7>-1 im stuck on it
All possible solutions for inequality are (-∞,-7)U(-7, ∞).
What is inequality?
In mathematics, a relationship between two expressions or values that are not equal to each other is called 'inequality. ' So, a lack of balance results in inequality.
The inequality q/7 > -1 is a mathematical statement that compares the value of q/7 to -1.
To solve the inequality, we can start by isolating q on one side of the inequality.
To do this, we need to multiply both sides of the inequality by 7:
q/7 * 7 > -1 * 7
q > -7
Now we have the inequality q > -7, this inequality states that q is greater than -7.
To find all possible solutions for the inequality, we can use interval notation. The interval notation for the solution of this inequality is (-infinity,-7)U(-7, infinity)
It means all real numbers except -7, the solution set is an open interval.
Alternatively, we can also graph the solution set of the inequality on a number line, shading the region that represents the solution. The shaded region will be all the points to the right of -7 on the number line.
Hence, all possible solutions for inequality are (-∞,-7)U(-7, ∞).

So, the final expression that represents the number of movie theater coupons Suresh has is 4.
Suresh has 4 coupon books, each containing 6 coupons, for a total of 4*6 = 24 coupons.
He wants to keep 1/3 of these coupons, so we can write an expression to represent this as: (1/3) * 24 = 8
So he keeps 8 coupons and gives away 24-8 = 16 coupons.
Out of the 8 coupons he keeps, 50% of them are for the movie theater, so we can write an expression to represent this as: 8 * 0.50 = 4
Therefore, the final expression that represents the number of movie theater coupons Suresh has is: 8 * 0.50 = 4
In this question, we have used the basic arithmetic operations like multiplication and subtraction to find the number of coupons Suresh keeps and gives away. And then we have used the percentage to find out how many movie theater coupons he has out of the total number of coupons he kept.

The square root of 131 is approximately 11.445 It lies between the two numbers 11 and 12, specifically, it is greater than 11 and less than 12.
We know that the square root of a number is the value that, when multiplied by itself, gives that number.
For example, the square root of 121 (which is 11) is 11 because 11 x 11 = 121.
In the same way, the square root of 131 is the number that, when multiplied by itself, will give 131.
Since 131 is a prime number and it is not a perfect square, the square root of 131 cannot be a whole number, it should be decimal and it lies between 11 and 12.

In a geometric series, the sum of the first three terms is 14. 25 and the sum of the first four terms is 24. 375. Find the first term and the common ratio.
The first term and the common ratio in the geometric series are 3 and 3/2.
What is a geometric series?A geometric series is described as the sum of the sequence of numbers. The sum of the nth term of a geometric sequence is expressed as:
Sₙ = a (r^n – 1) / r – 1
In this case, if the sum of the first three terms is 14.25, it means:
n = 3
S₃ = 14.25
Now, substitute the value into the formula:
Sn = a (r^n – 1) / r – 1
S₃ = a (r^3 – 1) / r – 1
14.25 = a (r^3 – 1) / r – 1
And, if the sum of the first four terms is 24.375, it means:
n = 4
S₄ = 24.375
Substitute the value into the formula:
Sₙ = a (r^n – 1) / r – 1
S₄ = a (r^4 – 1) / r – 1
24.375 = a (r^4 – 1) / r – 1
Then, we now can divide both above equations:
14.25 / 24.375 = r^3 – 1 / r^4 – 1
14.25r^4 – 14.25 = 24.375r^3 – 24.375
14.25r^4 – 24.375r^3 = –24.375 + 14.25
14.25r^4 – 24.375r^3 = –10.125
14.25r^4 – 24.375r^3 + 10.125 = 0
After factorizing we get:
r = 3/2
This is the common ratio.
Now, substitute the value of r into the equation
14.25 = a (r^3 – 1) / r – 1
14.25 = a ((3/2)^3 – 1) / (3/2) – 1
14.25 = a (19/8) / 0.5
19a / 8 = 14.25 * 0.5
19a / 8 = 7.125
19a = 57
a = 57 / 19
a = 3
Thus, the first term is 3.
Hence, the first term in the geometric series is 3 and the common ratio is 3/2.

Determine whether S is a basis for P3.

No, S is not a basis for P³. In order for a set of vectors to be a basis for a vector space, the vectors must be linearly independent and span the space.
In this case, the set of vectors does not span P³ because the highest order of the polynomials in S is t³, which does not span all of P³ which contains polynomials of order up to and including t³.
Additionally, the set of vectors is not linearly independent. For instance, 4t−t²= 5+3t−2t³, which means that the two vectors are linearly dependent. Therefore, S is not a basis for P³.
