Which equation can be rewritten as x + 4 = x2? Assume x greater-than 0 StartRoot x EndRoot + 2 = x StartRoot x + 2 EndRoot = x StartRoot x + 4 EndRoot = x StartRoot x squared + 16 EndRoot = x
We have been given an equation [tex]x+4=x^2[/tex]. We are also told that x is greater than 0. We are asked to choose the equation that can be written as our given equation.
Since x is greater than, so we will take positive root on both sides of our given equation as:
[tex]\sqrt{x+4}=\sqrt{x^2}[/tex]
[tex]\sqrt{x+4}=x[/tex]
Upon looking at our given choices, we can see that option C is same as our answer.
Therefore, option C is the correct choice.

The volume of the cone is 50π ft³. The height is 6 ft. What is the radius of the cone?
Answer:
r = 5 feet
Step-by-step explanation:
see attached for reference
recall that volume of a circular cone is given by
V = (1/3) πr²h, where
V = volume = given as 50π ft³
r = radius (we are asked to find this)
h = height of cone = given as 6 feet
Substituting the above known values into the equation:
V = (1/3) πr²h
50π = (1/3) π (r²)(6)
50π = π (r²)(2) (divide both sides by 2)
25π = π r² (divide both sides by π)
25 = r²
r = ±√25
r = ±5 (since radius cannot be negative, we select the positive value
r = 5 feet
solve the following system y=-2 -4x+8y=0
Answer:
x = -4
y = -2
Step-by-step explanation:
All you need to do is plug in the number given for y into the equation:
-4x + 8y = 0
-4x + 8(-2) = 0
-4x - 16 = 0
Add 16 to both sides:
-4x - 16 = 0
+ 16 + 16
____________
-4x = 16
Finally, divide both sides by -4:
-4x = 16
x = -4
So now you have, x = -4 and y = -2

0.114
0.139
0.574
Answer: 0.139
Step-by-step explanation:
From the given table, the total number of females = 252. The number of females that owned cats = 35. Therefore , the relative frequency of women that owned cats is given by -
Number of females that own cats/ Number of females
= 35/252 = 0.138888888889 = 0.139
Therefore, the relative frequency of women that owned cats is 0.139.
Answer: 0.139
Step-by-step explanation:
From the given table, the total number of females = 252. The number of females that owned cats = 35. Therefore , the relative frequency of women that owned cats is given by -
Number of females that own cats/ Number of females
= 35/252 = 0.138888888889 = 0.139
Therefore, the relative frequency of women that owned cats is 0.139.
How many times bigger is the 45,776 than 45.776
Answer:
54
Step-by-step explanation:
45,776 is exactly 1,000 times bigger than 45.776, as you can move the decimal point in 45.776 three places to the right to match the value of 45,776.
To determine how many times bigger 45,776 is than 45.776, we simply divide the larger number by the smaller number:
First, write down the two numbers: 45,776 and 45.776.Convert 45.776 to the same form as 45,776 by multiplying by 1000 (to move the decimal point three places to the right).The calculation will look like this: 45,776 / (45.776 x 1000) = 45,776 / 45,776 = 1,000.45,776 is 1,000 times bigger than 45.776.

there are 165 different plants in the school garden.of these ,132 will flower in spring.what percent of the plants will flower in spring
Answer:
80%
Step-by-step explanation:
132÷165=0.8
0.8×100=80%
80% of the plants in the school garden will flower in spring. The correct answer is [tex]$\boxed{80\%}$[/tex].
To find the percentage of plants that will flower in spring, we use the formula for percentage, which is:
[tex]\[ \text{Percentage} = \left( \frac{\text{Number of plants flowering in spring}}{\text{Total number of plants}} \right) \times 100\% \][/tex]
Given that there are 165 different plants in total and 132 of these will flower in spring, we can substitute these values into the formula:
[tex]\[ \text{Percentage} = \left( \frac{132}{165} \right) \times 100\% \][/tex]
Now, we simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 33:
[tex]\[ \text{Percentage} = \left( \frac{132 \div 33}{165 \div 33} \right) \times 100\% \] \[ \text{Percentage} = \left( \frac{4}{5} \right) \times 100\% \] \[ \text{Percentage} = 0.8 \times 100\% \] \[ \text{Percentage} = 80\% \][/tex]
The graph of an exponential model in the form y = a ⋅ bx passes through the points (2, 50) and (3, 250). Which point is also on the graph?
A. (0, 5) B. (1, 10) C. (4, 450) D. (5, 650)
The correct answer is B: (1, 10).
To determine which point is also on the graph of the exponential model [tex]\(y = a \cdot b^x\)[/tex], we can use the given points (2, 50) and (3, 250) to set up a system of equations.
For the point (2, 50):
[tex]\[50 = a \cdot b^2\][/tex]
For the point (3, 250):
[tex]\[250 = a \cdot b^3\][/tex]
Dividing the second equation by the first, we get:
[tex]\[\frac{250}{50} = \frac{a \cdot b^3}{a \cdot b^2}\][/tex]
Simplifying:
[tex]\[5 = b\][/tex]
Now that we know [tex]\(b = 5\)[/tex], we can substitute this back into either of the original equations to solve for [tex]\(a\)[/tex]. Using the first equation:
[tex]\[50 = a \cdot 5^2\][/tex]
Solving for \(a\):
[tex]\[a = 50/25 = 2\][/tex]
So, the exponential model is [tex]\(y = 2 \cdot 5^x\)[/tex].
Now we can check which of the given points is on the graph:
- For point (0, 5): [tex]\(y = 2 \cdot 5^0 = 2 \cdot 1 = 2\)[/tex]
- For point (1, 10): [tex]\(y = 2 \cdot 5^1 = 2 \cdot 5 = 10\)[/tex]
- For point (4, 450): [tex]\(y = 2 \cdot 5^4 = 2 \cdot 625 = 1250\)[/tex]
- For point (5, 650): [tex]\(y = 2 \cdot 5^5 = 2 \cdot 3125 = 6250\)[/tex]
The only point that satisfies the exponential model is (1, 10). Therefore, the correct answer is B. (1, 10).

how to find the designated sum in arithmetic series
Final answer:
To find the designated sum in an arithmetic series, use the formula (n/2)(a_1 + a_n), where n represents the number of terms, a_1 is the first term, and a_n is the last term.
Explanation:
How to Find the Designated Sum in Arithmetic Series
An arithmetic series is a sequence of numbers in which the difference between consecutive terms is constant. To find the designated sum in an arithmetic series, you can use the formula:
S_n = (n/2)(a_1 + a_n)
Identify the first term (a_1), the number of terms (n), and the common difference (d) of the arithmetic series.
Use the formula a_n = a_1 + (n-1)d to find the value of the last term in the series (a_n).
Substitute the values of a_1, a_n, and n into the formula S_n = (n/2)(a_1 + a_n) to calculate the designated sum of the arithmetic series.

Calculate the mean of each data set.
Calculate the mean absolute deviation (MAD) of each data set.
Which set is more variable? How do you know?
Answer:
Soil A mean: 71.8
Soil B mean: 72
Soil A MAD: 8.16
Soil B MAD: 5.4
Soil A set is more variable because it has a greater MAD. This feature is also seen in the stem-and-leaf plot, where Soil A set is more spread than Soil B set
Step-by-step explanation:
Soil A | |Soil B
|5|9
5 2 1 1|6|3 9
5 1 0|7|0 2 3 6 7 8
2 1|8|3
0|9|
Soil A mean: (65 + 62 + 61 + 61 + 75 + 71 + 70 + 82 + 81 + 90)/10 = 71.8
Soil B mean: (59 + 63 + 69 + 70 + 72 + 73 + 76 + 77 + 78 + 83)/10 = 72
Soil A MAD: ( |65 - 71.8| + |62 - 71.8| + |61 - 71.8| + |61 - 71.8| + |75 - 71.8| + |71 - 71.8| + |70 - 71.8| + |82 - 71.8| + |81 - 71.8| + |90 - 71.8|)/10 = 8.16
Soil B MAD: ( |59-72| + |63-72| + |69-72| + |70-72| + |72-72| + |73-72| + |76-72| + |77-72| + |78-72| + |83-72| )/10 = 5.4
