The height of a certain type of tree depends on the amount of sun it receives per year, described by the function Height(sun). What can be said about this function? Check all that apply.
A. Height is the dependent variable.
B. Height depends on sun.
C. sun is the output variable.
D. sun is the independent variable.
The Main answer is Option D. sun is the independent variable.
The height of a certain type of tree depends on the amount of sun it receives per year, described by the function Height(sun). sun is the independent variable can be said about this function.
In the given function Height(sun)
Height(sun), "sun" is the input variable, representing the amount of sun the tree receives per year. The height of the tree depends on the amount of sun it receives. Therefore, "sun" is the independent variable, as it is the input or the cause affecting the output, which is the height of the tree.
A. Height is the dependent variable.
B. Height depends on sun.
C. sun is the output variable.
These statements are incorrect because they incorrectly characterize the relationship between the variables. In this context, the height of the tree (Height) is dependent on the amount of sun (sun) it receives, making Height the dependent variable and sun the independent variable. So, options A, B, and C are incorrect.

Suppose that there are 67 butterfly species for every 22,000 insect species and there are 15,000 to 22,000 species of butterflies worldwide. how many insect species are there
Answer:
There are 4,925,250 to 7,223,700 insect species worldwide.
Step-by-step explanation:
Supposing that there are 67 butterfly species for every 22,000 insect species and there are 15,000 to 22,000 species of butterflies worldwide, in order to know how many insect species are there we have to do the following calculation:
22,000 (insect species) / 67 (butterfly species) = X (relation of butterfly and insect species)
22,000 / 67 = X
328.35 = X
There are 328.35 insect species for every butterfly species.
So, as there are 15,000 to 22,000 species worlwide, we have to multiply those numbers by 328.35 to know the total amount of insect species:
15,000 x 328.35 = 4,925,250
22,000 x 328.35 = 7,223,700
There are 4,925,250 to 7,223,700 insect species worldwide.

What is the product in simplest form? State any restrictions on the variable. z^2/z+1 * z^2+3Z+2/z^2+3z
The correct answer is option c. The product in simplest form is [tex]& \frac{z(z+2)}{z+3}[/tex] with restriction of [tex]z \neq-1,0,-3[/tex].
To find the product in simplest form and state any restrictions on the variable, we'll follow these steps:
1. Simplify each fraction where possible.
2. Multiply the fractions together.
3. State the restrictions on the variable.
Given expression:
[tex]\[\frac{z^2}{z+1} \times \frac{z^2 + 3z + 2}{z^2 + 3z}\][/tex]
Step 1: Factor each polynomial where possible
- [tex]\( z^2 \)[/tex] cannot be factored further.
- [tex]\( z + 1 \)[/tex] cannot be factored further.
- [tex]\( z^2 + 3z + 2 \)[/tex] can be factored into [tex]\((z + 1)(z + 2)\)[/tex].
- [tex]\( z^2 + 3z \)[/tex] can be factored into [tex]\(z(z + 3)\)[/tex].
So the given expression becomes:
[tex]\[\frac{z^2}{z + 1} \times \frac{(z + 1)(z + 2)}{z(z + 3)}\][/tex]
Step 2: Simplify the expression by canceling common factors
First, rewrite the expression to see the common factors more clearly:
[tex]\[\frac{z^2}{z + 1} \times \frac{(z + 1)(z + 2)}{z(z + 3)} = \frac{z^2 \cdot (z + 1)(z + 2)}{(z + 1) \cdot z \cdot (z + 3)}\][/tex]
Now, cancel the common factors:
- [tex]\( z^2 \)[/tex] and [tex]\( z \)[/tex] in the numerator and denominator:
[tex]\[\frac{z \cdot (z + 1)(z + 2)}{(z + 1) \cdot (z + 3)}\][/tex]
- [tex]\( z + 1 \)[/tex] in the numerator and denominator:
[tex]\[\frac{z \cdot (z + 2)}{z + 3}\][/tex]
Step 3: Simplified expression and restrictions
The simplified expression is:
[tex]\[\frac{z(z + 2)}{z + 3}\][/tex]
Restrictions on the variable
- The denominators in the original expression cannot be zero.
- [tex]\( z + 1 \neq 0 \implies z \neq -1 \)[/tex]
- [tex]\( z(z + 3) \neq 0 \implies z \neq 0 \text{ and } z \neq 3 \)[/tex]
Thus, the variable restrictions are:
[tex]\[z \neq -1, \quad z \neq 0, \quad z \neq 3\][/tex]
The complete question is
What is the product in simplest form? State any restrictions on the variable.
[tex]& \frac{z^2}{z+1} * \frac{z^2+3 z+2}{z^2+3 z} \\ } \\[/tex]

Lisa bought a share of stock for $48.24. She was paid a dividend of $12.06. What percent of the stock price is the dividend?
Answer:
The Percent of the Dividend is 25% of the Stock Price
Step-by-step explanation:
The Percent of the Dividend of the share of stock is calculated by the following formula.
[tex]P = \frac{1}{S} * D[/tex]
Where P is the percent of the dividend, S is the Stock Price, and D is the Dividend payment. Since we have all this information already we can just plug that into the formula to find out what percent of the Stock Price is the Dividend payment.
[tex]P = \frac{1}{48.24} * 12.06[/tex]
[tex]P = 0.020729*12.06[/tex]
[tex]P = 0.25[/tex]
We then turn the decimal into a percent, which gives us 25%.

Which is the best estimate for (8.9x10^8)/(3.3x10^4) written in scientific notation? A. 3x10^2 B. 6x10^2 C. 3x10^4 D. 6x10^4
Answer:
Option C
Step-by-step explanation:
The given expression is[tex]\frac{8.9\times 10^{8}}{3.3\times 10^{4}}[/tex]
Now we have to solve this.
[tex]\frac{8.9\times 10^{8}}{3.3\times 10^{4}}[/tex]
[tex]=\frac{8.9}{3.3}\times \frac{10^{8}}{10^{4}}[/tex]
= 2.70 × 10⁽⁸⁻⁴⁾
= 2.70 × 10⁴
≈ 3 × 10⁴
Therefore, Option C is the answer.

Read the following sentences from the passage.
John James lived in Nantes, France, when he was a small boy, although he was born in Louisiana. His father was a wealthy French gentleman, an officer in the French navy, and was much in America, so that John James was first in France and then in America until he was about twenty - five, at which time he settled in his native country for good.
Which explains the meaning of the word native ?
Question 1 options:
a person from another country
a person who moves from country to country
a person who loves his/her country
a person born in a certain place or country
Answer : a person born in a certain place or country
the word 'native' means "of indigenous origin or growth".
John James was of French origin although he was born in America.So, his native country would be France to which he finally shifted when he was 25 years old.

what is the sum of the finite arithmetic series (-5)+0+5+10+ ......+65
a. 900
b. 455
c. 450
d. 445
If you want to solve this problem using formulas, there are two important formulas:
t1 = first term = -5
tn = nth term = last term = -5
n = numbr of terms
Sn = sum of the n terms
tn = t1 + (n - 1)d ---> 65 = -5 + (n - 1)(5)
65 = -5 + 5n - 5
65 = -10 + 5n
75 = 5n
n = 15
Sn = n(t1 + tn)/2 ---> Sn = 15(-5 + 65)/2
Sn = 450
So ur answer rounds up to 450

The sum of the arithmetic series is 450, option c. Calculation: (15/2) * (first term + last term).
To find the sum of a finite arithmetic series, we can use the formula:
[tex]\[ S_n = \frac{n}{2} \times (a_1 + a_n) \][/tex]
where:
- [tex]\( S_n \)[/tex] is the sum of the series,
- [tex]\( n \)[/tex] is the number of terms in the series,
- [tex]\( a_1 \)[/tex] is the first term of the series, and
- [tex]\( a_n \)[/tex] is the last term of the series.
First, we need to find the number of terms, [tex]\( n \)[/tex]. The series is an arithmetic sequence with a common difference of [tex]\( 5 \)[/tex]. The first term is [tex]\( -5 \)[/tex], and the last term is [tex]\( 65 \)[/tex].
To find the number of terms, we can use the formula for the [tex]\( n^{th} \)[/tex] term of an arithmetic sequence:
[tex]\[ a_n = a_1 + (n - 1) \times d \][/tex]
where [tex]\( d \)[/tex] is the common difference.
Given [tex]\( a_n = 65 \)[/tex], [tex]\( a_1 = -5 \)[/tex], and [tex]\( d = 5 \)[/tex], we can solve for [tex]\( n \)[/tex]:
[tex]\[ 65 = -5 + (n - 1) \times 5 \][/tex]
[tex]\[ 65 = -5 + 5n - 5 \][/tex]
[tex]\[ 65 = 5n - 10 \][/tex]
[tex]\[ 75 = 5n \][/tex]
[tex]\[ n = 15 \][/tex]
So, there are [tex]\( 15 \)[/tex] terms in the series.
Now, we can use the formula for the sum of a finite arithmetic series:
[tex]\[ S_n = \frac{n}{2} \times (a_1 + a_n) \][/tex]
Plugging in the values:
[tex]\[ S_{15} = \frac{15}{2} \times (-5 + 65) \][/tex]
[tex]\[ S_{15} = \frac{15}{2} \times 60 \][/tex]
[tex]\[ S_{15} = \frac{15}{2} \times 60 = \frac{15 \times 60}{2} \][/tex]
[tex]\[ S_{15} = \frac{900}{2} \][/tex]
[tex]\[ S_{15} = 450 \][/tex]
So, the sum of the series is [tex]\( 450 \)[/tex], which corresponds to option [tex]\( c \)[/tex].
