its
= 4.1/100 × 30
= 41/1000 × 30
= 123/100
= 1.23%
Answer:
1.23
Step-by-step explanation:
Hey there !!!!!
4.1% of 30
if we solve it :
Y is 4.1% of 30
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 4.1% * 30
Converting percent to decimal:
p = 4.1%/100 = 0.041
Y = 0.041 * 30
Y = 1.23
therefore:
4.1% of 30 = 1.23

Write an exponential function in terms of x.
y=10
Answers
Answer:
y = 130,000(1.03)ˣ
Step-by-step explanation:
The general form of an exponetial function is y = abˣ, where a is the initial value (when x = 0), and b is the multiplier (the growth or decay factor). Here, we start with a population of 130,000, so our initial value a = 130,000. A growth of 3% each year represents a growth factor of 1.03, so after x years, the population y should be y = 130,000(1.03)ˣ.
The exponential function in terms of x and y is y = 130,000(1.03)ˣ
What is an exponential function ?The exponential function is a mathematical function denoted by
y = abˣ
where a is the initial value (when x = 0)
and b is the multiplier (the growth or decay factor).
population starts from 130,000, so
Initial value a = 130,000.
A growth of 3% each year represents a growth factor of 1.03,
so after x years, the population y should be
y = 130,000(1.03)ˣ
Therefore , The exponential function in terms of x and y is y = 130,000(1.03)ˣ

Lebron James's Free Throw % is 75%
What is the probability that he makes 6 Free Throws in a row?
Answer as a decimal rounded to 2 places.
Answers
Answer: 0.18
Step-by-step explanation:
From the question, we are informed that Lebron James's Free Throw % is 75%. The probability that he makes 6 Free Throws in a row would be gotten by multiplying 75% six times. This will be:
= 75% × 75% × 75% × 75% × 75% × 75%
= 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4
= 729/4096

Which of the following is the product (5y − 3)2?
Answers
Answer:
= 10y − 6 is your answer
Step-by-step explanation:
option B is correct, 25y²-30y+9 is the product of (5y − 3)².
What is Expression?The combination of numbers, variables, and operators is known as Expression.
The given expression is (5y − 3)²
The process of determining the product of two or more numbers is Multiplication.
The expression is five times of y minus three to the power of two.
From algebraic identity we have (a-b)²=a²+b²-2ab
Now (5y − 3)²
(5y)²+3²-2(5y)(3)
25y²+9-30y
Twenty five y to the power of two plus nine minus thirty times of y.
25y²-30y+9 is the expression after product of (5y − 3)².
Hence, option B is correct, 25y²-30y+9 is the product of (5y − 3)².

In the function f(x) = (x^2 -6x + ___) + 20, what number belongs in the blank to complete the square?
Answers
Answer:
blank = -11
Step-by-step explanation:
The given function is :
[tex]f(x) = (x^2 -6x+x)+20[/tex]
We need to find the number x such that it forms the complete square.
If x = -11, then it will becomes,
[tex]f(x) = (x^2 -6x+(-11))+20\\\\f(x)=x^2-6x+9[/tex]
We can write it as follows :
[tex]f(x)=x^2-2(1)(3x)+(3)^2[/tex] ..(1)
We know that,
[tex](a-b)^2=a^2-2ab+b^2[/tex] ...(2)
Comparing (1) and (2).
[tex]f(x)=(x-3)^2[/tex]
So, if we put the blank equals -11, then it will become the perfect square.

The diameter of a circle is 9 cm. Find its area to the nearest tenth.
Answers
Cut diameter in half to find radius
9/2 = 4.5
radius = 4.5
This is the formula for area of a circle:
pi * radius^2
pi * 4.5^2
20.25pi
Now find pi:
20.25 * pi = 63.6
Answer:
63.6 cm is the area
Answer:
63.6
Step-by-step explanation:
1. A = πr²
2. Find the radius (r). Since the radius of a circle is the diameter/2, the radius is 9/2, which is 4.5
3. Now that we know the radius, we plug it into our formula: A = π(4.5)²
4. Simplify: A = 3.14(20.25)
5. A = 63.62
6. Rounding to the nearest tenth makes your answer 63.6
