Answer:
y = -1/20(x + 3)²Step-by-step explanation:
Consider the parent function:
y = x²The graph of the function open up and the vertex is at the origin, the point (0, 0)
Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:
y = -x²The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:
y = -(x + 3)²Since all the options have 1/20 as a coefficient, our function is:
y = -1/20(x + 3)²This is option B
A TV that usually sells for $174.45 is on sale for 15% off. If sales tax on the TV is 8%, what is the price of the TV, including tax?
Answer:
$160.14
Step-by-step explanation:
15% of 174.45 = 26.16
174.45 - 26.16 = 148.28
8% of 148.28 = 11.86
148.28 + 11.86 = 160.14

A bacteria culture is grown with a population of 15 million cells and kept under observation. The bell population is found to double every hour. How can we use geometric sequences and series to find the total population after six hours? Show all work.
Answer:
Population after 6 hours is 2.44 *10^12
Step-by-step explanation:
The geometric population growth formula is
[tex]P = P_0 * e^{kt}[/tex]
Substituting the given values in above equation we get
[tex]P = 15 *10^6 * e^{2 * 6}\\P = 15 *10^6 * 162754.791\\P = 2.44 *10^{12}[/tex]
Population after 6 hours is 2.44 *10^12

Isabella invested $1300 in an account that pays 4.5% compounded annually. Assuming no deposits or withdrawals are made , find how much money Isabella would have in the account 14 years after her initial investment . Round to the nearest tenth.
Answer:
$2,407.5
Step-by-step explanation:
To solve this question, we will use the formula for calculating the amount formula as shown;
A =P(1+r)^n
Given that;
P = #$1300
r = 4.5% = 0.045
t = 14years
Substitute
A = 1300(1+0.045)^14
A = 1300(1.045)^14
A = 1300(1.8519)
A = 2,407.5
Hence Isabella would have $2,407.5 in her account after 14years

The hanger image represents a balanced equation (look at picture)
Answer:
A) [tex]27 = b + 9[/tex]
[tex]b=18[/tex]
Step-by-step explanation:
When given a balanced scale (represented by a hanger in this image), the sum of the values on one side equals the value on the other side. Thus, the equation that this hanger represents is the following:
[tex]27 = b + 9[/tex]
Use inverse operations to solve this equation,
[tex]27 = b + 9[/tex]
[tex]-9[/tex]
[tex]18 = b[/tex]
Work out the size of angle A.

PLEASE HELP ME Which of the following statements is not supported by the Venn diagram below?
There are 55 students taking biology and geometry.
There are 39 students who are not taking both geometry and biology.
There are more students in biology than students in geometry.
There are more students in geometry than students taking only biology.
Answer:
the answer is
Step-by-step explanation:
There are more students in biology than students in geometry.
The following statements does not support the given venn diagram:
There are 55 students taking geometry and biology.
There are more students in biology than students in geometry.
What are Venn diagrams?
The components of a set or group are schematically represented by a Venn diagram. It is a diagram that depicts every conceivable logical connection between a finite collection of sets or groups. It is also known as set diagram.
In a Venn diagram, sets of various elements are represented by many overlapping shapes (often circles). It seeks to give a pictorial representation of the components, emphasizing their similarities and differences.
Solution:
If we consider the first statement i.e, there are 55 students taking biology and geometry then through the venn diagram we get:17₊ 22 ₊8 = 47
The result of the addition operation is not equal to the number of students, hence it does not support to the statement.
If we consider the second statement i.e, there are 39 students who are not taking both biology and geometry then through the venn diagram we get:17 ₊ 22 = 39
The result of the addition operation is equal to the number of students, hence it supports the statement.
If we consider the third statement i.e, there are more students in biology than students in geometry then through the venn diagram we get:17 ₊ 8 = 25 and 8 ₊ 22 = 30
where, 25 < 30
Here, we can observe that students are less in biology and more in geometry, hence the result does not support the statement.
If we consider the fourth statement i.e, there are more students in geometry than students taking in biology, then through the venn diagram we get:22 ₊ 8 = 30
30 > 17
Here, we can observe that students are more in geometry than students taking only biology, hence the result supports the statement.
So the following statements does not support the venn diagram given:
There are 55 students taking geometry and biology.
There are more students in biology than students in geometry.

"sports discount" has uniforms for 68$. They are offering a 20% discount on each uniform, and a 7 percent sales tax will be applied to the discount price. What would be the final cost for eight uniforms after the discount and sales tax
Answer:
58.208 times 8 equals 465.664 rounded down to 465.66
Step-by-step explanation:
Answer:
$465.66
Step-by-step explanation:
First, we are buying 8 uniforms. Therefore, the total price on a normal day would be 8x68 = $544
However, on this day, there is a 20% discount. In other words, we are only paying 80% of the original price as percentages are always out of 100.
The price after the sports discount will be 544x0.8 = $435.2
On top of this, we have to pay a sales tax of 7 percent. The 7 percent is an additional cost to the discounted price of 435.2, hence we add 0.07 (7 percent in decimals) onto 1 (100% in decimals).
This gives us 435.2 x ( 1 + 0.07 ) = 465.664.
Because currency is to 2 decimal points (1 cent), the final answer will be 465.66, or 465 dollars and 66 cents.
