Volume of the log = 3.14*5^2* 30
Volume of the log = 2355 in^3

In IJK, the measure of K=90 degrees, JI=53, IK=45, and KJ=28, What ratio represents the sine of I?
Answers
The given triangle is a right angle triangle. The diagram is shown below.
From the triangle, considering angle I as the reference angle,
hypotenuse = JI = 53
adjacent side = IK = 45
opposite side = KJ = 28
To find Sin I, we would apply the Sine trigonometric ratio which is expressed as
Sin # = opposite side/hypotenuse
Thus,
Sin I = 28/53

4 ). Peter went to a bookstore to buy a pen and a binder. He used three- tenths of his money to pay the pen , while the rest of his money was used to pay the binder . the binder costs P64 more than the pen , what was the total price that Peter paid in the bookstore?
Answers
The total price that Peter paid in the bookstore is P91.43.
What is the total price?The first step is to determine the fraction of the amount that Peter has that he spent on the binder.
Fraction spent on a binder = 1 - fraction spent on pen
Fraction spent on a binder = 1 - 3/10
Fraction spent on a binder = 7/10
The next step is to divide the cost of the binder by the fraction spent on the binder.
Total price that Peter paid in the bookstore = price of the binder /fraction spent on the binder
Total price that Peter paid in the bookstore = P64 ÷ 7/10
Total price that Peter paid in the bookstore = P64 X 10/7 = P91.43

g(x)=4x^2+3 is the function g even odd or neither? prove it
Answers
Answer:
Even
Step-by-step explanation:
A function is called even if, for all values of x, f(-x) = f(x).
A function is called odd if, for all values of x, f(-x) = -f(x).
If none of these equalities is satisfied, the function is neither even nor odd.
In this question:
g(x) = 4x² + 3
g(-x) = 4(-x)² + 3 = 4x² + 3
Since g(-x) = g(x), the function g is even.

Mya, this is the solution:
Let's recall that the formula to solve for the surface area of a cylinder is:
A = 2 * π * r * h + 2 * π * r²
In our exercise, we have:
r = 8 cm
h = 7 cm
In consequence, replacing these values in the formula:
A = 2π * 7 * 8 + 2π * 8²
A = 2π * 56 + 2π * 64
A = 112π + 128π
A = 240π cm²
The correct answer is D. 240π cm²

Answers
The first 3 terms of the sequence are 202, 198, 194
Since 198 - 202 = -4
Since 194 - 198 = -4, then
The sequence is Arithmetic and decreases by 4
The rule of the arithmetic sequence is
[tex]a_n=a+(n-1)d[/tex]a is the first term
d is the common difference
n is the position of the term
Since the first term is 202, then
a = 202
Since the common difference is -4, then
d = -4
Since we need to find the 37th term, then
n = 37
Substitute them in the rule above
[tex]\begin{gathered} a_{37}=202+(37-1)(-4) \\ a_{37}=202+(36)(-4) \\ a_{37}=202-144 \\ a_{37}=58_{} \end{gathered}[/tex]The 37th term is 58
