The vertex form of the equation of
a parabola is y = 2(x +4)^2 - 7.What is the standard form of the equation?

Answer:

Quilt A: 35 green squares.

Quilt B: 12 blue squares.

Step-by-step explanation:

Based on the diagram, there are 3 blue squares for every 5 green squares. Then the ratio can be expressed as:

[tex]3:5\ or\ \frac{3}{5}[/tex]

Therefore, knowing the ratio, you can calculate:

- The number of green squares (G) in quilt A, as following:

[tex]\frac{3}{5}=\frac{21}{G}\\\\G=\frac{21*5}{3}\\G=35[/tex]

- The number of blue squares (B) in quilt B, as following:

[tex]\frac{3}{5}=\frac{B}{20}\\\\B=\frac{20*3}{5}\\B=12[/tex]

Answer:

Step-by-step explanation:

35 green, 12 blue.

Answer:

Option B True

Step-by-step explanation:

we know that

A function relates each element of a set  (input) with exactly one element of another set  (output)

1) "...each element..." means that every element in X (input)  is related to some element in Y (output)

2) "...exactly one..." means that a function is single valued. It will not give back 2 or more results for the same input

therefore

f(x) is a function

Answer:

[tex]96units^2[/tex]

Step-by-step explanation:

The total surface area of a cube is given by [tex]6l^2[/tex].

The first cube has side length [tex]l=6[/tex] units.

This cube has total surface area, [tex]6(6)^2=216units^2[/tex].

If the second cube is reduced in size by [tex]\frac{2}{3}[/tex], then the corresponding change in area is [tex]\frac{2^2}{3^2}=\frac{4}{9}[/tex].

the total surface area of the new cube is [tex]=\frac{4}{9}\times 216[/tex].

[tex]=96units^2[/tex]

Answer:

13.7

Step-by-step explanation:

Rewrite 15 - 1.3 as 15.0 - 1.3.

Then rewrite this result as

15.0

-  1.3

--------

and subtract as indicated.

First note that 15-1 = 14, and that 15-2= 13.  Thus, the correct answer will be between 13 and 14.

Subtract:

15.0

-  1.3

--------

This results in 13.7.

15 - 1.3 simplifies to 13.7 is the numeric result obtained after subtracting 1.3 from 15.

When we simplify the expression 15 - 1.3, we are performing basic arithmetic operations, specifically subtraction.

The step-by-step process is:

1. Write down the expression: 15 - 1.3

2. Perform the subtraction: Subtract 1.3 from 15

15 - 1.3 = 13.7

The result 13.7 is the difference between 15 and 1.3.

Answer:

1/4 acre every 1 hour

Step-by-step explanation:

divide 1/3 with 3/4 to find unit rate

Answer:

[tex]\frac{4}{9}acres/hr[/tex]

Step-by-step explanation:

Givens

To find the fraction that represents the constant per hour, we just need to divide both expression, like this

[tex]\frac{1}{3}acre \div \frac{3}{4}hr=\frac{1}{3}\times \frac{4}{3} =\frac{4}{9}acres/hr[/tex]

Therefore, the expression that represents the acres Jack can mow per hour is

[tex]\frac{4}{9}acres/hr[/tex]

That number is 80.

Answer:

A) 25 • 64

B) 25/100 • 64

C) .25 • 64

D) 64 divided by 25/100

E) 25 divided by 64/100

B and C i believe

The values that have the same value as 25% of 64 are Options B) 25/100 · 64 and C) .25 · 64, both yielding the correct value of 16 when calculated.

To find the same value as 25% of 64, we need to express 25% in different formats and apply it to 64. Option B) 25/100 · 64 translates the percent into a fraction, then multiplies by 64. Option C) .25 · 64 converts the percentage directly into a decimal, again multiplying by 64. Both expressions will yield the same result, which is the value of 25% of 64.

Options A), D), and E) do not give the correct value. A) is simply multiplication without considering the percentage, D) is incorrect because dividing 64 by a fraction is equivalent to multiplying by its reciprocal, and E) is an incorrect fraction division that does not represent 25% of 64.

Therefore, the correct answers are B) and C).

The sum its +2

2+2=4

4+2=6

6+2=8

8+2=10

And so on the numbers just keep sum for 2

Final answer:

To find the sum of even numbers from 2 to 70, we use the arithmetic sequence sum formula, resulting in a total sum of 1260.

Explanation:

The student's question is asking to find the sum of even numbers from 2 to 70. To do this, we can recognize that this is an arithmetic sequence, where the first term (a1) is 2, the last term (an) is 70, and the common difference (d) is 2, as we are stepping through even numbers only. This sequence has (70/2) terms, which gives us 35 terms.

The sum of an arithmetic sequence is given by the formula S = n/2 (a1 + an), where S is the sum, n is the number of terms, a1 is the first term, and an is the last term. By applying this formula, we can calculate the sum as follows: S = 35/2 (2 + 70) = 35 (72/2) = 35 (36) = 1260.

Therefore, the sum of the even numbers from 2 to 70 is 1260.

Answer: I believe the correct answer is always because function of a function would be function. So, the answer would be A. always:)

I may be the second one because the first one says 19 percent of the people who polled that are teachers prefer burgers. And the second one says 19 percent of the teachers polled prefer burgers, so I think it is the second answer.

Answer:

Step-by-step explanation:

First question:  19% of those who prefered burgers were teachers.  This is true.  We focus on the "Burgers" column and ignore the rest of the table.  

Second question:  19% of the teachers polled prefered burgers.  This is false.  If we look at the "teachers" line, we see that 6 teachers prefered pizza and 4 prefered burgers.  The percentage of teachers prefering burgers was 4 / (4+6), or 4/10, or 40%.

Third question (impossible to read):  19% of the people polled prefer ..... .

False.  That 19% does not pertain to the entire group of people polled.

80% × 494.4 =

(80 ÷ 100) × 494.4 =

(80 × 494.4) ÷ 100 =

39,552 ÷ 100 =

395.52;

proof

395.52 ÷ 494.4 =

0.8 =

0.8 × 100/100 =

0.8 × 100% =

(0.8 × 100)% =

80%

Answer:

The solutions of the equation are -41.8° , 0.0° , 41.8°

Step-by-step explanation:

∵ 3 sin²Ф - 2 sinФ = 0 is a quadratic function

∵ The domain of the function is -90° ≤ Ф ≤ 90°

- Lets take sinФ as a common factor

∴ sinФ (3 sinФ - 2) = 0

- Two terms multiplied by each other = 0

∴ One of them must be equal zero

∴ sinФ = 0 or 3 sinФ - 2 = 0

- If sinФ = 0 ⇒ Ф = 0.0°

- If 3 sinФ - 2 = 0 ⇒ 3 sinФ = 2 ⇒ sin Ф = 2/3

∵ sinФ 2/3

∴ Ф = 41.8° ⇒ Ф ≤ 90° (in first quadrant)

∵ -90° ≤ Ф ≤ 90°

∴ Ф = -41.8° ⇒ Ф ≥ -90° (in fourth quadrant)

∴ The solutions of the equation are -41.8° , 0.0° , 41.8°

Step-by-step explanation:

Correct Answer is B and C 0.0, and 41.8

Answer: True

For example, the mean and median of any arithmetic function is equivalent.

Answer:

True

Step-by-step explanation:

Averages are sometimes called "measure of central tendency". In a distribution with a positive skew, the median has a higher value than the mean. In a normal distribution, the mean, median and mode have the same value. The median has only 50% of the cases below it ONLY in a normal distribution.

I think it was C:15 but I am not exactly sure

The equation that relates the number of cups brewed to the ounces of coffee remaining is necessary to determine the initial amount of coffee in the pack, which is not provided in the question.

The question does not provide the specific equation that describes the relationship between the number of cups brewed (x) and the ounces of coffee (y) remaining in the pack. However, the task is to determine how much ground coffee, in ounces, was in the full pack when Mr. Finch purchased it. To solve this, we would typically need to know how much coffee is used per cup and have an initial amount representing the full pack. If the equation was provided, we could use it to calculate the initial amount of the coffee. Without the equation, we cannot proceed with the calculation. Ensuring all critical information is provided in a word problem is crucial for solving it.

Answer:

A meter is 100 times larger than a centimeter

Step-by-step explanation:

A meter is larger than a cm. u can try it on a ruler. look  at the cm notice how it is smaller than a meter.

Answer:

It depends.

Step-by-step explanation:

I won't say centimeter is less or more than a meter, because 1 meter is equal to 100 center centimeter. But when you compare different measurement it can, for example:

2 m = 200 cm (Both are same)

3 m > 250 cm (m is greater, actually 3m = 300 cm)

4 m < 450 cm (cm is greater, 4 m = 400 cm)

Answer:

-1/6 u + 2/3 = v

Step-by-step explanation:

You can solve for v here so that the equation is in terms of u.

-3u + 6 = 18v - 6                Add 6 to both sides

-3u + 12 = 18v                    Divide everything by 18

-3/18 u + 12/18 = v             Simplify fractions

-1/6 u + 2/3 = v

Answer:

$3098.93

Step-by-step explanation:

We can use the formula for compound growth to solve this. The formula is:

[tex]F=P(1+r)^t[/tex]

Where

F is the future value (the value at end of 14 years, our answer)

P is the initial amount invested ($1250)

r is the interest rate, in decimal (6.7% is 0.067)

t is the time in years (14, in our case)

Plugging in all the information we have:

[tex]F=P(1+r)^t\\F=1250(1+0.067)^14\\F=1250(1.067)^14\\F=3098.93[/tex]

The account will accrue $3098.93 after 14 years.

Among the given options, option C) 2/3 is a possible probability for event Q that is greater than 1/2. Therefore, the correct answer is C) 2/3.

If event Q is more likely to occur than event T and the probability of event T is 1/2, then a possible probability of event Q could be any value greater than 1/2.

Let's dive deeper into the concept of probability and explore why option C) 2/3 is a possible probability for event Q.

When we say that event Q is more likely to occur than event T, it means that the probability of event Q is greater than the probability of event T. In this case, we are given that the probability of event T is 1/2.

To find a possible probability for event Q, select a value greater than 1/2. Option C) 2/3 fits this criterion. It indicates that event Q has a probability of 2/3, which is greater than 1/2.

Complete question

Event Q is more likely to occur than Event T. If P(Event T) = 1/2, what is a possible probability of Event Q? A)1/4 B)1/2 C)2/3 D)It cannot be determined.

The possible probability of event q is  is  [tex]\(\frac{3}{4}\).[/tex]

Since event Q is more likely than event T, the probability of event Q must be greater than the probability of event T.

The probability of event T is [tex]\(\frac{1}{2}\),[/tex] so the probability of event Q must be greater than [tex]\(\frac{1}{2}\).[/tex]

This satisfies the condition that event Q is more likely than event T because [tex]\(\frac{3}{4}\) (or 0.75)[/tex] is greater than [tex]\(\frac{1}{2}\) (or 0.5).[/tex]

 It is important to note that there are infinitely many probabilities that are greater than [tex]\(\frac{1}{2}\)[/tex] and less than or equal to 1 (the maximum probability for any event).

However, the question asks for a possible probability, and [tex]\(\frac{3}{4}\) is[/tex] a valid example that meets the given criteria.
