Answer:
Answers B, E and F (1, 5 and 6).
Step-by-step explanation:
In an exponential equation, (y=ab^x), the "b" value must be a decimal less than 1 (but greater than 0) for it to be considered an exponential decay function. Only equations B, E and F have a "b" value that fits this criteria.
A house purchased for $226,000 has lost 4% of its value each year for the past five years. What is it worth now?
Answer:
The answer would be $184,274.23.
Step-by-step explanation:
After a 4% annual decrease in value over five years, a house that was bought for $226,000 would be worth around $183,896.7.
Explanation:The student's question pertains to a situation where a house's value depreciates, in this case, at a rate of 4% per year for five years. To find out how much the house would be worth now, we need to employ the formula for depreciations, that is P = P0 (1 - r)^n, where P is the final value, P0 the initial value, r the rate of decrease and n the number of periods the decrease has occurred over.
In this case, P0 would be the initial value of the house $226,000, r would be 4% (or 0.04 as a decimal), and n would be the number of years, which is 5. Substituting these values into the formula gives us and calculated we get P = $226,000 * (1 - 0.04)^5 = $183,896.7.
So after a 4% annual decrease in value over five years, the house that was bought for $226,000 would now be worth around $183,896.7.

the solid below is made from 1 yard cubes. find it's surface area
Answer:
surface area = 28 yard²
Step-by-step explanation:
given data
1 unit length of cube = 1 yd
solution
As given image shown that rectangular solid has length 5 units, width 2 units, and height 2 units.
so we get here surface area that is we get by area of each of its faces
we can see three face are
A front = L × W = 2 × 2 = 4
A side = L × W = 5 × 2 = 10
A top = L × W = 5 × 2 = 10
so here
surface area = ( front + back ) + ( left side + right side ) + ( top + bottom ) ................1
surface area = ( 2 × front ) + ( 2 × left side ) + ( 2 × top )
surface area = ( 2 × 4 ) + ( 2 × 10 ) + ( 2 × 10 )
surface area = 8 + 20 + 20
surface area = 28 yard²

A normal distribution has a mean of 186.4 and a standard deviation of 48.9.
What range of values represents the upper 2.5% of the data?
a
X > 235.3
b
X > 333.1
c
X > 284.2
d
X > 186.4
We have been given that a normal distribution has a mean of 186.4 and a standard deviation of 48.9. We are asked to find the range of value that represents the upper 2.5% of the data.
We know that upper 2.5% of data would be 97.5% of data.
We will use z-score formula to solve our given problem.
[tex]z=\frac{x-\mu}{\sigma}[/tex], where,
z = z-score,
x = Random sample score,
[tex]\mu[/tex] = Mean,
[tex]\sigma[/tex] = Standard deviation.
Now we will use normal distribution table to find z-score corresponding to 97.5% area or 0.975.
We can see from the normal distribution table that z-score corresponding to area 0.975 is [tex]1.96[/tex].
[tex]1.96=\frac{x-186.4}{48.9}[/tex]
Let us solve for x.
[tex]1.96\cdot 48.9=\frac{x-186.4}{48.9}\cdot 48.9[/tex]
[tex]95.844=x-186.4[/tex]
[tex]95.844+186.4=x-186.4+186.4[/tex]
[tex]282.244=x[/tex]
Therefore, the range [tex]x>282.244[/tex] represents the upper 2.5% of the data.
What is the probability that the product of two dice is greater than
15 on two separate rolls?
Answer:
25/324
Step-by-step explanation:
Make a table of possible products:
[tex]\left[\begin{array}{ccccccc}&1&2&3&4&5&6\\1&1&2&3&4&5&6\\2&2&4&6&8&10&12\\3&3&6&9&12&15&18\\4&4&8&12&16&20&24\\5&5&10&15&20&25&30\\6&6&12&18&24&30&36\end{array}\right][/tex]
Of the 36 results, 10 are greater than 15.
The probability the product is greater than 15 on a single roll is 10/36 = 5/18.
The probability the product is greater than 15 on two rolls is (5/18)² = 25/324.
What are the measures of those two angles? I’ll mark brainliest!
Answer:
Two angles of a quadrilateral : 220 and 90 deg.
The other two angles (x and y) are in ratio 2:3.
We have:
x + y = 360 - 220 - 90 = 50 (property of sum of 4 angles in quadrilateral)
x/y = 2/3 => x = 2y/3
=>2y/3 + y = 50
=> 5y/3 =50
=> 5y = 150
=> y = 30
=> x = 2 x 30/3 = 20
=> Two other angles are 20 and 30 deg

find the area of the kite.
area = _[tex]m^{2}[/tex]
Answer:
24 m^2
Step-by-step explanation:
The area of a kite is the product of the diagonals divided by 2.
If the diagonals have lengths a and b, then area = ab/2
area = ab/2
a = horizontal diagonal = 2 m + 6 m = 8 m
b = vertical diagonal = 3 m + 3 m = 6 m
area = (8 m)(6 m)/2 = (48 m^2)/2 = 24 m^2

Rectangle QUAD has coordinates Q(4,5), U(4,10), A(11,10), and D(11,5). Upper Q prime Upper U prime Upper A prime Upper D primeQ′U′A′D′ is the image of QUAD after a dilation with center (0,0) and scale factor 5. What is the length of segment Upper Q prime Upper U primeQ′U′?
Answer:
25
Step-by-step explanation:
Answer: 25
find the length of segment QU.
First, we must find out what the coordinates are.
Q=(4,5) U=(4,10)
Then, Setup your equation by making the first coordinate pair equal. So,
Q= (4,5) would now equal Q=(5,5). That means we added 1. (when you add x ((x=the number you add to make equal)) you add x to the other side as well)
So, now we would add 1 (or how many you got) to U. Thus,
U=(4,10) would now equal Q=(5,10).
Next, set up the equation.
[tex]\sqrt{(Q)^{2} +(U)^{2}[/tex] (Q=(5,5) and U=(5,10).)
* You will now be subtracting the coordinates so, Q=(5-5) and U=(5-10)*
Next, Substitute the equation.
[tex]\sqrt{(5-5^{2} +(5-10)^{2}[/tex]
After, we solve.
[tex]\sqrt{0^{2} +(5-10)^{2}[/tex]
*the sum of two opposites equals 0. 5-5=0*
Next, Subtract (5-10).
[tex]\sqrt{0^{2} +(-5)^{2}[/tex]
Next, 0 raised to any positive power equals 0
[tex]\sqrt{0+(-5)^{2}[/tex]
Next, When adding or subtracting 0, the quantity does not change.
[tex]\sqrt{(-5)^{2}[/tex]
Next, Reduce the index of the radical and exponent 2.
[tex]|-5| = 5[/tex]
So, The length of segment is 5.
Now, find the length of segment Upper Q'U', multiply the length of segment QU by the scale factor.
scale factor in this equation is 5.
Now, multiply.
5·5 = 25
So, the length of segment Q'U' is 25.
The length of segment Q'U' after the dilation with a scale factor of 5 is 25 units.
To find the length of segment Q'U' after the dilation with a scale factor of 5, we can calculate it step by step:
1. Calculate the new coordinates of Q' and U' after the dilation with a scale factor of 5 and center (0,0):
Q' coordinates: (4 5, 5 5) = (20, 25)
U' coordinates: (4 5, 10 5) = (20, 50)
2. Determine the distance between Q' and U' using the distance formula:
- Horizontal distance: 20 - 20 = 0
- Vertical distance: 50 - 25 = 25
3. Calculate the length of segment
using the Pythagorean theorem:
- Length = sqrt(0^2 + 25^2)
- Length = sqrt(0 + 625)
- Length = sqrt(625)
- Length = 25 units
Therefore, the length of segment Q'U' after the dilation with a scale factor of 5 is 25 units.

He has between 10 and 20 batteries. He counts the batteries by putting them into piles of 4 and finds that he has 3 left over. He then counted them by putting them into piles of 3 and found that he had one left over. How many batteries does he have?
Answer:
15 batteries
Step-by-step explanation:
If he puts the batteries in piles of 4, and there is 3 left over, the number of batteries he can have is:
2 piles: 4*2 + 3 = 11
3 piles: 4*3 + 3 = 15
4 piles: 4*4 + 3 = 19
Then, when he puts in piles of 3, there is no batteries left over, so the number of batteries is a multiple of 3.
From the 3 possibilities above (11, 15 and 19), only the number 15 is a multiple of 3, so the number of batteries is 15.

Find the missing factor. 5y^2+4y-1=(5y-1)()
Answer:
(5y−1)(y+1)
Step-by-step explanation:
Answer:
(y + 1 )
Step-by-step explanation:
Given
5y² + 4y - 1
Consider the factors of the product of the y² term and the y- term which sum to give the coefficient of the y- term
product = 5 × - 1 = - 5 and sum = + 4
The factors are + 5 and - 1
Use these factors to split the y- term
5y² + 5y - y - 1 ( factor the first/second and third/fourth terms )
= 5y(y + 1) - 1(y + 1) ← factor out (y + 1) from each term
= (y + 1)(5y - 1)
The missing factor is (y + 1)

The range of possible sizes for side 'x' is from 1.5 to 4.5, inclusive of both endpoints.
Explanation:The question "What is the range of possible sizes for side xxx?" refers to finding the possible values that the variable 'x' can take. From the information provided, we understand that 'x' can be any number in the inclusive range from 1.5 to 4.5, which can be denoted mathematically as 1.5 ≤ x ≤ 4.5. This means that the smallest value 'x' can be is 1.5, and the largest value is 4.5. The range of possible sizes for 'x' is therefore between 1.5 and 4.5, including both of these endpoints.

Which is the graph of f(x) = -(x + 3)(x + 1)?
Answer:
Step-by-step explanation:
Setting f(x) = -(x + 3)(x + 1) = 0 leads to identifying two roots/solutions of this equation: x = -3 and x = -1. The axis of symmetry is a vertical line halfway between these two roots: x = -2. This x = -2 is also the x-coordinate of the vertex. Evaluating f(x) = -(x + 3)(x + 1) at x = -2 gives us the y-coordinate of the vertex: y = -(-2 + 3)(-2 + 1) = -(1)(-1) = 1.
In summary, the vertex is at (-2, 1) and the two x-intercepts are (-3, 0) and (-1, 0). The y-intercept is found by setting x = 0 and finding y:
f(0) = -(0 + 3)(0 + 1) = -3, or (0, -3)

A:10.8 feet
B:9.2 feet
C:2.4 feet
D:3.7 feet
The ladder is 9.2 feet up the building
The length (L) of the ladder is given as:
[tex]L = 10ft[/tex]
The distance (d) from the edge of the building is
[tex]d = 4ft[/tex]
The distance up the ladder is the height (h) of the ladder on the wall.
This is calculated using the following Pythagoras theorem
[tex]L^2 = d^2 + h^2[/tex]
So, we have:
[tex]10^2 = 4^2 + h^2[/tex]
Evaluate the exponents
[tex]100 = 16 + h^2[/tex]
Subtract 16 from both sides
[tex]84 = h^2[/tex]
