Y=52(0.42)^x identify if it's growth or decay and determine the percentage rate of increase or decrease
Answer:
58%
Step-by-step explanation:
Given the exponential relation :
Y=52(0.42)^x
Since 0.42 is less than 1, then we can infer that the expression is a Decay function ;
. General form of a exponential function :
y = A(1 - r)^x ; r = Decay rate
Comparing the general equation with the equation given ;
The percentage rate of decrease is obtained thus :
1 - r = 0.42
1 - 0.42 = r
r = 0.58
Rate = 0.58 * 100%
Rate = 58%

which prism has the least volume please help
Answer:
Prism A
Step-by-step explanation:
formula for prism triangular prisms: V=1/2(bhl) so V=1/2(4 x 7 x 9) V=126 m
formula for rectangular prisms: V=b x h x l so V= 8 x 8 x 2 V=128
126 is less than (<) 128 so Prism A

Louis wants to carpet the rectangular floor of his basement. The basement has an area of 363 square feet. The width of the basement is 1 3 its length. What is the length of Louis's basement? The length is feet.
Answer:
the length is 33 feet
Step-by-step explanation:
The computation of the length is shown below:
Let us assume the length be x
So the width be 1 by 3 x
And the area is 363 square feet
So
As we know that
Area = length × width
363 = x × 1 ÷ 3 x
363 = 1 ÷ 3x^2
Now
363 × 3 = x^2
1089 = x^2
x = 33 feet
hence, the length is 33 feet

Answer:
x=85, y=45
Step-by-step explanation:
Answer:
x = 85 degrees
y = 45 degrees
Step-by-step explanation:
x = 180 - 95 (Angles on a straight line add up to 180 degrees.)
x = 85 degrees
y = 180 - 50 - 85 (Interior angles of a triangle add up to 180 degrees.)
y = 45 degrees

Notice that the result is a polynomial expression divided by a second polynomial expression. In this section, we will explore quotients of polynomial expressions.
Simplifying Rational Expressions
The quotient of two polynomial expressions is called a rational expression. We can apply the properties of fractions to rational expressions, such as simplifying the expressions by canceling common factors from the numerator and the denominator. To do this, we first need to factor both the numerator and denominator. Let’s start with the rational expression shown.

Convert the circle to standard form.
[tex] {9x}^{2} + {9y}^{2} + 18x + 9y - 36 = 0[/tex]
Answer:
(x + 1)² + (y + 1)² = (√6)²
Step-by-step explanation:
Group the x- and y- terms together:
9x^2 + 18x + 9y^2 + 9y = 36
Factor out the coefficient 9:
x^2 + 2x + y^2 + y = 4
Complete the square of x^2 + 2x and then do the same for y^2 + 2y:
x^2 + 2x + 1 - 1 + y^2 + 2y + 1 - 1 = 4
Rewrite x^2 + 2x + 1 as the square of the binomial x + 1:
(x + 1)^2 + (y + 1)^2 - 2 = 4
Collect the constant terms on the right side:
(x + 1)^2 + (y + 1)^2 = 6
Rewrite 6 as (√6)^2:
(x + 1)² + (y + 1)² = (√6)² is the equation in standard form (x - h)² + (y - k)² = r²
Completing the square is done as follows: x^2 + 2x
Start with x^2 + 2x
1. Take half of the coefficient of x, which results in 2/2, or 1
2. Square this result and add it to, and subtract it from x^2 + 2x
x^2 + 2x + 1 - 1
3. Rewrite the first three terms as the square of a binomial:
x^2 + 2x + 1 - 1 = (x + 1)² - 1.
Do the same for y² + 2y.
You have a hemisphere with a volume of 6. What is the surface area with a sphere with the same diameter. Round to the nearest thousandth.
Answer:
(the volume of the hemisphere has no units, so i will suppose that it is 6m^3)
For a sphere of radius R, the volume is:
V = (4/3)*pi*R^3
Where pi = 3.14
And a hemisphere is half of a sphere, then the volume of a hemisphere of radius R is:
V = (1/2)*(4/3)*pi*R^3
We know that the volume of the hemisphere is 6 m^3, then we have the equation:
6 m^3 = (1/2)*(4/3)*3.14*R^3
Now we can solve this for R.
6 m^3 = 2.1*R^3
∛(6 m^3/2.1) = R = 1.41 m
The radius of the hemisphere is 1.41m
Now we want to find the surface of a sphere with this radius (if the radius is the same, then the diameter is the same)
For a sphere of radius R, the surface is:
S = 4*pi*R^2
Then the surface of this sphere is:
S = 4*3.14*(1.41 m)^2 = 24.971 m^2

what is the power times a power
where does the power go in a equation
how do you put a power in a equation
Answer:
The "power rule" tells us that to raise a power to a power, just multiply the exponents. Here you see that 52 raised to the 3rd power is equal to 56. The quotient rule tells us that we can divide two powers with the same base by subtracting the exponents.

On a certain hot summer's day, 288 people used the public swimming pool. The daily prices are $1.75 for children and $2.50 for adults. The receipts for admission totaled $528.00. How many children and how many adults swam at the public pool that day?
Answer:
See explanation
Step-by-step explanation:
Let the number of adults = a and the number of children = c.
Since the number of people using the pool is 288, we know that a + c = 288
Based on the price information, we know that 1.75c + 2.5a = 528
Combining these two equations allows us to solve for the values of a and c, the process for which follows
a = 288 - c
1.75c + 2.5(288 - c) = 528
c = 256
a = 288 - c = 288 - 256 = 32
a = 32
c = 256

What is the volume of the shaded solid? Round to the nearest tenth of a cubic unit. 11.6 units3 45.4 units3 57.0 units3 68.6 units3
Answer:
45.44units^3
Step-by-step explanation:
Volume of the shaded part = Volume of the triangular based prism - Volume of square based prism
Volume of prism = Base area * Height
Volume of the triangular based prism = (5 * 4 * 5.7)/2
Volume of the triangular based prism = 57units^3
Volume of square based prism = 1.7* 1.7 * 4
Volume of square based prism = 11.56units^3
Taking the difference
Volume of the shaded solid = 57 - 11.56
Volume of the shaded solid = 45.44units^3
