Using a directrix of y = −2 and a focus of (2, 6), what quadratic function is created?
here are the answers given
\/
f(x) = −one eighth (x − 2)2 − 2
f(x) = one sixteenth (x − 2)2 + 2
f(x) = one eighth (x − 2)2 − 2
f(x) = −one sixteenth (x + 2)2 − 2
Answers
Answer:
f(x)=1/16(x-2)^2+2
Step-by-step explanation:
The Equation can be written like this:
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...
f(x) = 1/16(x -2)^2 +2

The Cost C (in dollars) of making n bracelets is represented by C=45n+125. How many bracelets are made when the cost is $845?
Answers
So we know the cost is $845, which means this is the cost or our C. Lets input this into our equation and solve.
845 = 45n + 125.
Subtract from both sides:
845-125 = 45n + 125-125
720 = 45n
Divide by 45:
720 / 45 = 45n / 45
16 = n
This means that 16 bracelets can be made if the cost is 845.
We can also re-input the information into the equation to be extra sure!
845 = 45 (16) + 125.
845 = 720 + 125.
845 = 845
Yes!
I hope this helps! :)

Answers
To add these fractions, we need to find a common denominator. The least common multiple of 7, 4, and 3 is 84, so we will use 84 as the common denominator.
2/7 + (-3/4) + (-2/7) + 4/3
= (2/7) * (12/12) + (-3/4) * (21/21) + (-2/7) * (12/12) + (4/3) * (28/28) (multiplying each fraction by an equivalent form to get a common denominator of 84)
= 24/84 - 63/84 - 24/84 + 112/84 (simplifying each fraction)
= -51/84 + 112/84 (combining like terms)
= 61/84 (simplifying the resulting fraction)
Therefore, 2/7 + (-3/4) + (-2/7) + 4/3 = 61/84.
Answer:
7/12
Step-by-step explanation:
2/7 + (-3/4) + (-2/7) + 4/3
2/7 - 3/4 - 2/7 + 4/3 (+ * - = -)
2/7 - 2/7 - 3/4 + 4/3 (Distribution Property)
0 - 3/4 + 4/3
- 3/4 + 4/3
4/3 - 3/4 (Distribution Property)
LCM = 3 * 4
= 12
(16 - 9) / 12
7/12
So, the final answer is 7/12.

No the given relation is not a function because for one input we are getting two different values of output which negates the definition of the function.
A relation is said to be a function when each and every element of domain has a unique and distinct image means we will get only one output per input.So
statement 1: No, because for each input there is not exactly one output . This is true.statement 2: No, because for each output there is not exactly one input. This is false.statement 3:Yes, because for each input there is exactly one output .This is false.statement 4:Yes, because for each output there is exactly one input.This is also false.Hence the given relation is not a function.

The given relation is not a function because for each input (x-value), there is not exactly one output (y-value).
In a function, each input (x-value) should have only one corresponding output (y-value). However, in this relation, the input value of 1 has two different output values: -2 and 3. Therefore, it violates the definition of a function.
To illustrate this, let's look at the points (-2, 0), (1, -2), and (1, 3). The x-value of 1 appears twice in the relation, but it has two different y-values associated with it. This means that for the input value of 1, there is not exactly one output value, which is why the given relation is not a function.
In conclusion, the relation is not a function because for each input there is not exactly one output.

Dena wants to make a birdhouse with the leftover wood. she needs 105 3/5 centimeters of wood for the birdhouse. write and evaluate an expression to determine how much how much more wood will be needed. PLEASE HELPPP
Answers
Answer:
Step-by-step explanation:
hi sorry if this is wrong but the answer is Dena wants to make a birdhouse with the leftover wood. but She needs 105 3/5 of wood
Dena needs 1.15 centimeters more of wood is needed to make the birdhouse.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
A. To find the total length of wood left over, we need to add the lengths of all 5 pieces of wood.
We can represent each piece of wood with a fraction and then add all the fractions.
The total length of wood can be represented as:
12.7 + 26 3/10 + 15 4/5 + 21 1/4 + 19.2 = (12.7 + 26 + 15 + 21 + 19.2) + (3/10 + 4/5 + 1/4)
To simplify the expression, we can convert the mixed numbers (26 3/10 and 21 1/4) to improper fractions and convert the fractional part of decimals (3/10 and 4/5) to decimals:
12.7 + 26 3/10 = 12.7 + 26.3
15 4/5 = 15 + 0.8
21 1/4 = 21 + 0.25
3/10 = 0.3
4/5 = 0.8
So, the expression becomes:
12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2 = (12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2) + 0.3 + 0.8 = 104.45
Therefore, the total length of wood left over is 104.45 centimeters.
B. To determine how much more wood will be needed for the birdhouse, we can subtract the total length of wood left over from the required length:
105 3/5 - 104.45 = (105 + 0.6) - 104.45 = 105.6 - 104.45 = 1.15
Therefore, 1.15 centimeters more of wood is needed to make the birdhouse.

Hey there!
A "flip" can be considered a reflection.

A "slide" is a translation.
None of these transformations change the way a shape looks, or the size of the shape. They only change how the shape is oriented.

Flip is considered a reflection. Spin is a rotation. Slide is a translation.
