a2+4a+16

Which expressions are differences of squares?

Select each correct answer.

t2−4

h2−20

x2−169

a2+1

Answers

Answer: Perfect squares are the middle two. Difference of squares are t^2 -4 and x^2 - 169

First, to be a perfect square the last term must be a perfect square number. Only 169, 49 and 16 are perfect squares. Second, the middle term must be twice the square root of the last term.

You can check this by using foil on the following expression:
(x + 13)(x + 13) You will get x^2 + 26x + 169 which is one of the perfect square trinomials.

For the difference of squares, you must be using subtraction and have two perfect squares.

t^2 - 4 and x^2 - 169 are the right answers, just took the test.

Julia measured the high temperature in her town for one week. Using the chart below, find the mean absolute deviation for the high temperatures. Round your answer to the nearest tenth. Be sure to show your work for finding:

the mean of the set of data
the distance of each number from the mean

Answers

It's not much but to find the mean you add up all of the numbers in the set, and then divide by how many numbers there are. so like, if you have : 2, 2, and 3. You'd add them and get 7, then divide by 3 because there are three separate numbers.

rectangle abcd is similar to rectangle pqrs. given ab=14 cm, BC=8cm and pq=21cm, calculate the length of QR

Answers

QR =12 because you set up a proportion 21/14=x/8 then cross multiply and get 14x=168 then you divide and get 12

The length of QR in rectangle PQRS is 12 cm, found by setting up the proportional relationship 14/21 = 8/QR, where 14 cm and 8 cm are the lengths of sides AB and BC of rectangle ABCD, respectively, and 21 cm is the length of side PQ of rectangle PQRS.

Since rectangle ABCD is similar to rectangle PQRS, their corresponding sides are proportional. To find the length of QR, we will set up a proportion using the given lengths:

AB/PQ = BC/QR

Substituting the given lengths:

14/21 = 8/QR

Now, solve for QR:

QR = (21 * 8) / 14

QR = 168 / 14

QR = 12 cm

So, the length of QR in rectangle PQRS is 12 cm.

If c=3k+4 and d=7+9k^2, what is d in terms of c?

Answers

Answer:

d = (c -4)² +7 = c² -8c +23

Step-by-step explanation:

Both 'c' and 'd' are expressed in terms of the variable k. In general, that variable is eliminated by writing k in terms of 'c' or 'd', then substituting for k in the other equation.

Eliminating k

We recognize that the 9k² term in the expression for 'd' is the square of the 3k term in the expression for 'c'. That means we don't have to solve for k; we only need to solve for 3k. The equation for 'c' gives an easy way to do that.

c = 3k +4

c -4 = 3k . . . . . . . subtract 4 to get an expression for 3k

Substituting into the equation for 'd', we have ...

d =7 +9k²

d = 7 +(3k)² . . . . . writing 9k² in terms of 3k

d = 7 +(c -4)² . . . . substituting for 3k. This is d in terms of c.

This can be simplified to ...

d = c² -8c +23 . . . . another form of d in terms of c.

Final answer:

To express 'd' in terms of 'c', solve the first equation for 'k' and substitute this value into the second equation. This yields: d=7+((c-4)^2)/3.

Explanation:

To express d in terms of c, we first need to make k the subject of c=3k+4. We do this by subtracting 4 from both sides, getting c-4=3k, and then dividing both sides by 3, which gives us k=(c-4)/3. Next, we substitute this value of k into the second equation: d=7+9k^2. Substituting, we get d=7+9*((c-4)/3)^2, which, when simplified, gives the result d=7+((c-4)^2)/3. This is the expression for d in terms of c.

Suppose two fractions are both less than 1. Can their sum be greater than 1? greater than 2?

Answers

Their sum can be greater than 1 but it would be less than 2.

The sum can be greater than 1, but not two. For example say the fractions are, 3/4 and 5/6, the total is , 1 7/12. Which is greater than 1 but not two. It cannot be greater than 2 because fractions are a part of 1.UNLESS, it is a mixed number fractions, than they can be infinitely great. Such as 123 3/4 + 45 2/4 is definitely greater than 2.

x = h= -b/2a = -(-12)/2(1) = 6
k = f(h) = 36 - 12(6) + 27
k = -9

so vertex (6,-9)

y = a(x - h)^2 + k

so
y = (x - 6)^2 - 9
x intercept when y = 0
x^2−12x+27 = 0
(x - 9)(x - 3) = 0
x - 9 = 0; x = 9
x - 3 = 0; x = 3

Answer: The average age is 7.1 years.

This problem is an example of when we need to take a weighted average. We simply can't just find the average of 5 and 8, because there are different children of each each.

To start, lets multiply the total number of children by their individual ages.

6 x 5 = 30 years

There are 142 years among the 20 years, so divide 142 by 20. This gives us an average age of 7.1 years.

Answers

This is a system of equations, and I am assuming that you are being asked to solve it.

This is finding the point where these two lines intersect.

The key to solving these algebraically is finding one part in terms of another part and substituting.

We can solve this system by Gaussian elimination, first by multiplying the second equation in its entirety by 2, so that the x-terms will cancel.

We have
[tex]16x-10y=10[/tex]
and
[tex]2(-8x-6y=6)[/tex].

The last equation is rewritten as [tex]-16x-12y=12[/tex].

Now, we cancel the x-terms.

[tex]16x-10y=10[/tex]
[tex]-16x-12y=12[/tex]

[tex]-22y=22 \\ y = -1[/tex]

We have our value for y, so we just plug this back into any of the original equations to get x.

[tex]16x-10(-1)=10\\16x=0\\x=0[/tex]

Thus, the solution to the system of equations is the point [tex](0,-1)[/tex].

What is Exponential Form?

The exponential form is an easier way of writing repeated multiplication involving base and exponents. It has a base and a power

The exponential form of a number is a way of representing a number using exponents, where the base is typically a number greater than 1.

It is often used in mathematics and science to represent large or small numbers more efficiently. It can also be used to simplify certain mathematical operations, such as multiplication and division, by using the properties of exponents.

Given data ,

Let the exponential form of the number be A

Now , the value of A = 9.03×10²

To convert 9.03×10² to standard form, we need to multiply the number by the appropriate power of 10 so that it is expressed as a number between 1 and 10.

Starting with 9.03×10² , we can move the decimal point two places to the right to get:

9.03×10^2 = 903

So the standard form of 9.03×10² is simply 903

Hence , the standard form is A = 903

A spherical balloon is inflated until its diameter is 24 in. Air is then released from the balloon until its diameter is 18 in. Approximately many cubic inches of air were released from the balloon?

formula: V =4π(r^3)/3 **make sure you use the radius and not the diameter**

Answers

Answer:
amount of air released = 4184.6 in³

Explanation:
We can get the volume of released air by calculating the difference between the volume of the balloon before and after the air was released. This difference will represent the amount of released air.

Initial volume of balloon:
V = [tex] \frac{4}{3} [/tex]πr³
We have diameter = 24 in
Therefore:
radius = 24/2 = 12 in
volume = [tex] \frac{4}{3} [/tex]π(12)³
initial volume = 2304π in³

Final volume of balloon:
V = [tex] \frac{4}{3} [/tex]πr³
We have diameter = 18 in
Therefore:
radius = 18/2 = 9 in
volume = [tex] \frac{4}{3} [/tex]π(9)³
final volume = 972π in³

Amount of air released:
amount of air released = initial volume - final volume
amount of air released = 2304π - 972π
amount of air released = 1332π = 4184.6 in³
