Answer:

x = -4 and x = -12

Step-by-step explanation:

x^2 + 16x + 48 = 0 is to be factored.

Note that 48 is the product of 4 and 12 and that the sum of 4 and 12 is 16.

Therefore,

x^2 + 16x + 48 = 0 in factored form is:

(x + 4)(x + 12) = 0, so that x + 4 = 0 → x = -4, and

                                        x + 12 = 0  → x = -12

Answer:

(x + 4) (x + 12)

Step-by-step explanation:

to factor x² + 16x + 48 = 0, you need to find 2 numbers that when multiplied together give you 48 and when added together give you 16

you can list the factors of 48 and see what adds up together to give you 16, but here is a hint:

the numbers probably end in a 2, 4, 0, 6, 5, or 1, as a pair of these numbers added together give us 6. i looked at a factor chart and saw that 12 and 4 that when added together, give us 16 and when multiplied, give us 48

in factored form it looks like the following:

(x + 4) (x + 12)

this would be the answer in factored form

Answer:

x = 5

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of squares on the other 2 sides, that is

x² + 12² = 13²

x² + 144 = 169 ( subtract 144 from both sides )

x² = 25 ( take the square root of both sides )

x = [tex]\sqrt{25}[/tex] = 5

Answer:

x = 25

Step-by-step explanation:

We are given a right angled triangle and we are to find the value of x.

For that, we will use the Pythagoras Theorem.

[tex] 1 3 ^ 2 = x ^ 2 + 1 2 ^ 2 [/tex]

[tex] 1 6 9 = x ^ 2 + 1 4 4 [/tex]

[tex] x ^ 2 = 1 6 9 - 1 4 4 [/tex]

[tex] x ^ 2 = 2 5 [/tex]

Taking square root on both sides to get:

The factorization of [tex]729x^{15} +1000[/tex] is [tex](9x^{5} +10)(81x^{10} -90x^{5} +100)[/tex]

Step-by-step explanation:

This is a case of factorization by sum and difference of cubes, this type of factorization applies only in binomials of the form [tex](a^{3} +b^{3} )[/tex] or [tex](a^{3} -b^{3})[/tex]. It is easy to recognize because the coefficients of the terms are perfect cube numbers (which means numbers that have exact cubic root, such as 1, 8, 27, 64, 125, 216, 343, 512, 729, 1000, etc.) and the exponents of the letters a and b are multiples of three (such as 3, 6, 9, 12, 15, 18, etc.).

Let's solve the factorization of [tex]729x^{15} +1000[/tex] by using the sum and difference of cubes factorization.

1.) We calculate the cubic root of each term in the equation [tex]729x^{15} +1000[/tex], and the exponent of the letter x is divided by 3.

[tex]\sqrt[3]{729x^{15}} =9x^{5}[/tex]

[tex]1000=10^{3}[/tex] then [tex]\sqrt[3]{10^{3}} =10[/tex]

So, we got that

[tex]729x^{15} +1000=(9x^{5})^{3} + (10)^{3}[/tex] which has the form of [tex](a^{3} +b^{3} )[/tex] which means is a sum of cubes.

Sum of cubes

[tex](a^{3} +b^{3} )=(a+b)(a^{2} -ab+b^{2})[/tex]

with [tex]a= 9x^{5}[/tex] y [tex]b=10[/tex]

2.) Solving the sum of cubes.

[tex](9x^{5})^{3} + (10)^{3}=(9x^{5} +10)((9x^{5})^{2}-(9x^{5})(10)+10^{2} )[/tex]

[tex](9x^{5})^{3} + (10)^{3}=(9x^{5} +10)(81x^{10}-90x^{5}+100)[/tex]

Answer:

Step-by-step explanation:

So it would be A.

Explanation: The middle number is 2 and the last number is -8.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 2

Multiply together to get -8

Can you think of the two numbers?

Try -2 and 4:

-2+4 = 2

-2*4 = -8

Fill in the blanks in

(x+_)(x+_)

with -2 and 4 to get...

(x-2)(x+4)

Answer:

(x−2)(x+4)

A. (x+4)(x-2). The factorization of the quadratic equation x²+2x-8 given by the graph is (x+4)(x-2).

From the graph shown in the image we can see the parabola's cut points, in the y-axis is -4 and the x-axis is 2, then we write the product changing the signs (x+4)(x-2) = x²+2x-8

Use the half-angle identities.

[tex]\sin^2x=\dfrac{1-\cos2x}2[/tex]

[tex]\implies\sin^4x=\left(\dfrac{1-\cos2x}2\right)^2=\dfrac{1-2\cos2x+\cos^22x}4[/tex]

[tex]\cos^2x=\dfrac{1+\cos2x}2[/tex]

[tex]\implies\sin^4x=\dfrac{1-2\cos2x+\frac{1+\cos4x}2}4=\dfrac{3-4\cos2x+\cos4x}8[/tex]

sin^4(x) can be expressed in terms of cosine as (1 - cos^2(x))^2.

Rewrite sin^4(x) in terms of cosine by using the Pythagorean identity for trigonometric functions, which relates sin^2(x) and cos^2(x):

sin^2(x) + cos^2(x) = 1

Now, solve for sin^2(x):

sin^2(x) = 1 - cos^2(x)

Now, square sin^2(x) to get sin^4(x):

(sin^2(x))^2 = (1 - cos^2(x))^2

sin^4(x) = (1 - cos^2(x))^2

So, sin^4(x) can be expressed in terms of cosine as (1 - cos^2(x))^2.

Answer: Edgur eats 12 ounces of popcorn. Before he ate any, he had 2 pounds of popcorn. How much popcorn, in ounces, of popcorn does Edgur have now? Edgur has 20 ounces of popcorn.

Step-by-step explanation:

Pounds to ounces: 1 pound = 16 ounces.

2 * 16 = 32.

He ate 12 of those ounces. 32 - 12 = 20.

Final answer:

To solve a problem involving subtraction of pounds and ounces, convert everything to ounces, subtract, and convert back if necessary. In this example, after removing 3 pounds 5 ounces from 9 pounds 8 ounces, the remaining weight is 6 pounds 3 ounces.

Explanation:

Let's create a subtraction problem involving pounds and ounces. Imagine you have a sack of potatoes weighing 9 pounds 8 ounces, and you remove a bag of potatoes weighing 3 pounds 5 ounces. How much does the sack of potatoes now weigh?

First, we need to ensure that both weights are in the same units. We have:

Initial weight: 9 pounds 8 ounces

Weight removed: 3 pounds 5 ounces

To subtract these weights, we will convert pounds to ounces for each weight, then subtract, and finally convert back to pounds and ounces if necessary.

Convert 9 pounds to ounces: 9 × 16 = 144 ounces

Therefore, the initial weight in ounces is 144 ounces + 8 ounces = 152 ounces.

Convert 3 pounds to ounces: 3 × 16 = 48 ounces

The weight removed in ounces is 48 ounces + 5 ounces = 53 ounces.

Subtract the smaller weight from the initial weight: 152 ounces - 53 ounces = 99 ounces

Now we convert 99 ounces back to pounds and ounces. Since 1 pound is 16 ounces:

99 ÷ 16 = 6 pounds with a remainder of 3 ounces.

So, the sack of potatoes now weighs 6 pounds 3 ounces.

Answer:

Not all relationships are functions, but all functions are also relationships

Step-by-step explanation:

A relationship is a correspondence between two sets of values.

A relationship assigns values from an output set called range to a set and input called a domain.

On the other hand, a relation is a function if and only if there is only one value of the output set (Range) assigning to each value of the input set (Domain).

In other words, if an input value [tex]x_1[/tex] is assigned two or more output values [tex]y_1[/tex], [tex]y_2[/tex], [tex]y_3[/tex] .. then the relationship is not a function. This means that not all relationships are functions.

[tex]y=\±\sqrt{x} +3[/tex]   is a relation but it is not a function.

because when x = 4 then y = 1 and y = 5.

Not all relationships are functions, but all functions are also relationships

Final answer:

A relation is a set of ordered pairs, while a function is a relation where each input value is associated with only one output value. Not every relation is a function, but every function is a relation.

Explanation:

A relation is a set of ordered pairs where each input value is associated with one or more output values. On the other hand, a function is a relation where each input value is associated with only one output value.

Not every relation is a function. For example, the relation {(1,2), (1,3), (2,4)} is not a function because the input value 1 is associated with two different output values (2 and 3). However, every function is a relation because it establishes a relationship between the input and output values.

Answer:

Yes he is Correct

Step-by-step explanation:

When multiply with numbers like 10,100,1000 ect or even like 20,200,2000 then you have to break it down. Since multiply by zero equals 0 anyways you will only have to focus on the number that is in front of it. And just and the zeros to the back of the number.

Answer:

Yes he is correct

Step-by-step explanation:

Whenever we are multiplying any number with  10 or multiples of ten we simply add the zeros to the end of that number.

For example:

134 x  10   =  1340

As you can see, to get the answer, you simply need to add 0 to the end of 134

Also 10 x 10 = 100

To get the answer we simply added zero to the end of ten which then give us   100

12 x 10= ?  all you need to do is to add zero to the end of 12 which will give us 120

13 x 100 =?  In this case, since the zeros are two, you will simply add two zeros to the end of  13 which will give you the answer 1300

So Marcel can find 52 times 10 by simply adding a 0 to the end of 52 to get 520 as the correct answer.
