What does 1+3x-7x equal to

Answer:

3^2X5

Step-by-step explanation:

Students learn that the prime factorization of a number is the given number written as the product of its prime factors. For example, to find the prime factorization of 45, use a factor tree to find that 45 is 5 x 9, and 9 is 3 x 3. So the prime factorization of 45 is 5 x 3 x 3, or 5 x 3^2.

Answer:

Option B, 3^2 * 5

Step-by-step explanation:

Step 1:  Find the prime factorization of 45

45 = 9 * 5

9 can be simplified as 3^2

5 cannot be simplified because it is a prime number

9 * 5

3^2 * 5

So, 45 = 3^2 * 5

Answer:  Option B, 3^2 * 5

Answer:

144

Step-by-step explanation:

12X12 is also 12+12+12+12+12+12+12+12+12+12+12+12

Lets simplify that though.

12(10)+12(2) (since 10 plus 2 is 12)

120+24

144

The value of the expression 12 * 12 = 144

The meaning of the expression 12 * 12 could also be interpreted as adding 12 in 12 places.

We could rewrite as thus :

Adding the above would give a value of 144.

Hence, 12 * 12 = 144

The measure of arcWUX in circle V of the given diagram with the circle geometry is; C: 120°

From the complete image as seen online, we can say that;

The measure of ∠WUX is similar to the measure of vertex ∠V.

To get the measure of angle V (∠V), we will use the sum of angles in a triangle theorem to get;

30 + ∠V + ∠X = 180

60 + ∠V = 180

∠V = 180 - 60

∠V = 120°

Since ∠V = arcWUX

Then, measure of arcWUX is 120°

Clockwise rotation and translation 3 units to the left.

Given that the function f(x) = x translates to f(x) = 0.2 (x+3)

When we add 3 units to x, then the graph x shift left by 3 units.

By dilation, the graph will rotate clockwise.

Hence, the function f(x) = x translates to f(x) = x, clockwise rotation and translation 3 units to the left.

Step-by-step explanation:

36= 3 equal parts

so: 36/3 =12

One part=12

so 2 parts is 12*2

12*2=24mm is the answer

The measure of the matching side of the smaller triangle is 24 millimeters.

When dealing with similar triangles, the lengths of corresponding sides are proportional. This means that if one triangle has sides that are a constant multiple of the sides of another triangle, we can find the length of a matching side by using that constant multiple. In this case, the sides of the smaller triangle are said to be 2/3 the lengths of the sides of the larger triangle.

To find the matching side of the smaller triangle when a side of the larger triangle is 36 mm, we use the proportionality factor, which is 2/3. Therefore, the length of the corresponding side in the smaller triangle is 2/3 of 36 mm, which can be calculated as:

(2/3) * 36 mm = 24 mm

So, the measure of the matching side of the smaller triangle is 24 millimeters.

Option B

[tex]3 x\sqrt{2} x[/tex] is the choice equivalent to [tex]\sqrt{6} x^{2} \cdot \sqrt{3} x[/tex]

Solution:

Step 1:

When we multiply two roots i.e. [tex]\sqrt{6} x^{2}[/tex] and [tex]\sqrt{3} x[/tex] the values are multiplied and still kept inside the root.

So [tex]\sqrt{6} x^{2}[/tex] × [tex]\sqrt{3} x[/tex] = [tex]\sqrt{6} x^{2} \times 3 x[/tex].

Step 2:

We then multiply the values in the root.

[tex]\sqrt{6} x^{2} \times 3 x[/tex] = [tex]\sqrt{18 x^{3}}[/tex]

Step 3;

We take the values out of the root by splitting up the value.

[tex]{18 x^{3}}[/tex] = [tex](9 \times 2)\left(x^{2} \times x\right)[/tex]

[tex]\sqrt{9}=3[/tex] and [tex]\sqrt{x^{2}}=x[/tex]

So [tex]\sqrt{18 x^{3}}[/tex] = [tex]\sqrt{9} \times 2 \times x^{2} \times x[/tex]

When we take values out of the root, we replace it with the square-rooted value on the outside.

[tex]\sqrt{18 x^{3}}[/tex] = [tex]3 x \sqrt{2 x}[/tex].

Thus option B is correct

Answer:

Each result is equally likely

The sample space has 36 different outcomes

Step-by-step explanation:

A number cube has 6 sides, and there are 2 number cubes so there are 36 possible outcomes because 6²=36

Remind me if im wrong

The statements which are true are each result is equally likely , the sample space has 36 different outcomes and the total roll of 7 is very likely.

When a green number cube and a red number cube are rolled, the outcomes indeed have specific characteristics. Here's a breakdown based on the selections provided in the question:

Each result is equally likely is true, because when rolling two fair six-sided dice (or in this case, cubes), each side of each cube has an equal chance of landing face up, making each combination of the two cubes equally likely

The sample space has 36 different outcomes is  true, as each cube has 6 faces, and when two are rolled together, the total number of possible outcomes (or the sample space) is 6 times 6, equating to 36

The sample space has 11 different outcomes is false, because as previously stated, there are 36 possible outcomes based on the combination of two six-sided dice.

A total roll of 7 is very likely is true, not because it will happen every time, but because there are more combinations (6 in total) that sum to 7 than any other number. These are (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1).

Answer:

In 1981 was the building worth double it’s value.

Step-by-step explanation:

Given : A townhouse in San Francisco was purchased for $80,000 in 1975. The appreciation of the building is modeled by the equation : [tex]A=80000(1.12)^t[/tex], where t represents time in years.

To find : In what year was the building worth double it’s value in 1975?

Solution :

The amount is $80,000.

The building worth double it’s value in 1975.

i.e. amount became A=2(80000).

Substitute in the model,

[tex]2(80000)=80000(1.12)^t[/tex]

[tex](1.12)^t=\frac{2(80000)}{80000}[/tex]

[tex](1.12)^t=2[/tex]

Taking log both side,

[tex]t\log (1.12)=\log 2[/tex]

[tex]t=\frac{\log 2}{\log (1.12)}[/tex]

[tex]t=6.11[/tex]

i.e. Approx in 6 years.

So, 1975+6=1981

Therefore, in 1981 was the building worth double it’s value.

The building was worth double its value in [tex]1975[/tex] around the year [tex]1981[/tex]

To determine in what year the building was worth double its value in [tex]1975[/tex], we need to set up the equation based on the appreciation model given:

[tex]\[ A = 80000 \times (1.12)^t \][/tex]

Here, [tex]\( A \)[/tex] represents the current value of the townhouse in dollars, and [tex]\( t \)[/tex] represents the time in years since [tex]1975.[/tex]

We want to find the year [tex]\( t \)[/tex] when the value [tex]\( A \)[/tex] is double the initial value of [tex]\$80,000[/tex]

[tex]\[ A = 2 \times 80000 = 160000 \][/tex]

Now, substitute [tex]\( A = 160000 \)[/tex] into the equation:

[tex]\[ 160000 = 80000 \times (1.12)^t \][/tex]

Divide both sides by [tex]80000[/tex] to solve for [tex]\( (1.12)^t \)[/tex]

[tex]\[ 2 = (1.12)^t \][/tex]

To solve for [tex]\( t \)[/tex], take the natural logarithm ([tex]ln[/tex]) of both sides:

[tex]\[ \ln(2) = \ln((1.12)^t) \][/tex]

[tex]\[ \ln(2) = t \times \ln(1.12) \][/tex]

Now, divide both sides by [tex]\( \ln(1.12) \)[/tex] to solve for [tex]\( t \)[/tex]:

[tex]\[ t = \frac{\ln(2)}{\ln(1.12)} \][/tex]

Using a calculator to find the approximate value:

[tex]\[ t = \frac{0.6931}{0.1178} = 5.88 \][/tex]

Since [tex]\( t \)[/tex] represents years after [tex]1975[/tex], we add this to [tex]1975[/tex] to find the year when the building was worth double its value in [tex]1975[/tex]:

[tex]\[ \text{Year} = 1975 + 5.88 = 1980.88 \][/tex]

In [tex]1981[/tex], the building was worth double its value in [tex]1975.[/tex]

0 3

3 0

Step-by-step explanation:

The correct table of values for the equation y = -x + 3 is x; y; -3; 6; 0; 3; 3; 0.

Let's go through the steps to find the values of y for the given equation y = -x + 3 for the specified values of x:

1. For x = -3:

y = -(-3) + 3 = 6

2. For x = 0:

y = -(0) + 3 = 3

3. For x = 3:

y = -3 + 3 = 0

Therefore, the correct table of values is:

x     y

-3    6

0     3

3     0

The correct values are [tex]\(x \; y \; -3 \; 6 \; 0 \; 3 \; 3 \; 0\)[/tex].

The population of Gloomy Falls will decrease to approximately 816 residents after three years, due to a yearly decline of 4.5%.

The problem posed involves calculating the decreasing population of a town under a hypothetical scenario. Given that Gloomy Falls has a starting population of 937, and it decreases by 4.5% annually, we need to apply this percentage decrease over a three-year period. The formula to calculate the population after each year is: Population after n years = Initial population × (1 - rate of decrease)n, where n is the number of years.

So we calculate the population as follows:

After rounding, we can estimate that approximately 816 residents will be left after three years. This is purely a mathematical exercise and the scenario of a serial killer is just for illustrative purposes.

Step-by-step explanation: Any function of the form f (x) = m x + b, where m is not equal to 0 is called a linear function. The domain of this function is the set of all real numbers. The range of f is the set of all real numbers. The graph of f is a line with slope m and y intercept b.

Answer:

f(2)= 5

Step-by-step explanation:

Given f(x) = -x² + 1

f(2) = -2² + 1 = 4 + 1 = 5

f(2) means the value of x = 2

Hence we substitute the value of X into f(x) = -x² + 1

Answer:

The first thing we need to do is find the area of the rectangle...

l x w = A

7 x 8 = 56

So the area of the first rectangle is 56m.

Now we multiply each dimension by 5...

8 x 5 = 40

7 x 5 = 35

So, now the width is 40m and the length is 35m,

Then, find the area of the new rectangle...

35 x 40 = 1400

The area of this rectangle is 1,400m!

1,400 / 56 = 25

So, by multiplying each dimension by 5, the area is now multiplied by 25!
