Answer:

[tex]U_n=5(-2)^{n-1}[/tex]

Step-by-step explanation:

Given a geometric sequence, the nth term of the geometric sequence is obtained by using the formula:

[tex]U_n=ar^{n-1}[/tex]

If the eleventh term, [tex]a_{11}=5120[/tex]

and the common ratio, r=-2.

Then:

[tex]5120=a(-2)^{11-1}\\a=\frac{5120}{2^{10}} =5[/tex]

The explicit formula for the sequence is:

[tex]U_n=5(-2)^{n-1}[/tex]

Answer:

(x-9)^3

Step-by-step explanation:

so first you see "the cube" which means ^3 to whatever you are going to have

the difference means the answer of a subtraction equation

the the difference between "a number" (x) and 9 is (x-9)

then you see that when "adding" those together you get (x-9)^3

Answer:

x = -24/5

Step-by-step explanation:

2x – 3 + 3x = – 27

Combine like terms

5x -3 = -27

Add 3 to each side

5x-3+3 = -27+3

5x = -24

Divide each side by 5

5x/5 = -24/5

x = -24/5

Answer:

x= -24/5

Step-by-step explanation:

To solve, we need to get x by itself.

2x – 3 + 3x = – 27

Combine like terms

(2x+3x)-3= -27

5x-3=-27

Add 3 to both sides

5x-3+3=-27+3

5x= -24

Divide both sides by 5

5x/5= -24/5

x= -24/5

Answer:

x=12, both angles are 144°

Step-by-step explanation:

Since the angles are Z-angles (lookup 'alternate exterior angles') they are the same.

This means that 10x+24 = 6x+72, which can be simplified to

10-6x = 72-24

4x = 48

x = 12

Substitute x=12 in either expression and you get 144.

The only definite conclusion from the given information is that the product of b and c is positive, while the signs of a and b individually cannot be determined conclusively. Here option B is correct.

The product of a and c is negative: We cannot determine the signs of a and c individually, but from the given information, we can say that their product is negative. This is because the sum of a and c is 0 (a + b + c = 0), and b is positive.

If both a and c were positive or negative, their sum would be positive or negative, respectively. Therefore, one must be positive and the other negative for their sum to be zero.

The product of b and c is positive: As mentioned above, we know that b is positive and the product of a and c is negative. Since the sum of a, b, and c is zero, if b is positive and the product of a and c is negative, then the product of b and c must be positive to balance the equation.

The product of b and O is 0: This statement is always true because any number multiplied by zero is zero.

The product of a and b is positive: We cannot determine the signs of a and b individually based on the given information. As explained earlier, we only know that their sum is positive and the product of a and c is negative.

Therefore, the only statement that is guaranteed to be true based on the given information is that the product of b and c is positive. Here option B is correct.

Answer:

The equation, or more accurately, the system of equations we can use is:

x + y = 18

2x = y

Step-by-step explanation:

Consider that the cost of the shirt was x.

Consider the cost of the pants to be y.

Then, you can say that 2x = y since twice the cost of the shirt would give you the cost of the pants which are represented by y.

The next piece of information can be used to form the equation x + y = 18 since the cost of a pair of pants and a shirt are, in total, $18.

We can use a system of equations to answer this.

2x = y

x + y = 18

Since y = 2x, use substitution.

x + 2x = 18

3x = 18    (Divide both sides by 3)

x = 6

x represents the cost of the shirt and thus, the shirt costs $6.

The equation, or more accurately, the system of equations we can use is:

x + y = 18

2x = y

Answer:

2s+1s = 18

3s = 18

Since the question asks for the equation

Step-by-step explanation:

Let s = cost of 1 shirt

Pants cost twice the price of 1 shirt

p = 2s

We are buying 1 pair of pants and 1 shirt for 18 dollars

2s+1s = 18

Combining like terms

3s = 18

Either equation can be used to solve

We can divide by 3 to solve for the cost of 1 shirt

3s/3 = 18/3

s = 6

Answer:

Step-by-step explanation:

You can solve it :

Then choose the numbers from the options that satisfies the inequality, x < -5

Answer:

Step-by-step explanation:

(-2)*(-4)=8, 8<10

(-2)*2=-2, -2<10

(-2)*(-6)=12, 12>10

(-2)*(-5)=10, 10=10, so it is not true

(-2)*(-8)=16, 16>10

(-2)*0=0, 0<10

(-2)*(-43)=86, 86>10

Answer:

I think that it is 295 degrees

Step-by-step explanation:

The height of the fire department is 244.72 m

Step-by-step explanation:

A)

Angle of elevation = 73°

The distance between the two buildings = 46 m

tan 73° = b/46

tan 73° = 3.27

tan 73° = b/46

3.27 = b/46

b = 3.27 x 46

b = 150.42 m

B)

Angel of depression= 64°

The distance between the two buildings = 46 m

tan 64° = a/46

tan 64° = 2.05

tan 64° a/46

2.05 = a/46

a = 2.05 x 46

a = 94.3 m

The total height of the fire department building = a + b

= 94.3 + 150.42

= 244.72 m

The height of the fire department is 244.72 m

x = 17

Step-by-step explanation:

3(x - 4) - 12 = 2(x - 6) + 5

3x - 12 - 12 = 2x - 12 + 5

3x - 24 = 2x - 7

3x - 2x = -7 + 24

x = 17

Answer:

x=17

Step-by-step explanation:

3(x - 4) - 12 = 2(x - 6) + 5

Distribute

3x -12 -12 =2x-12 +5

Combine like terms

3x-24 = 2x -7

Subtract 2x from each side

3x-2x -24 =2x-2x-7

x-24 = -7

Add 24 from each side

x-24+24 = -7+24

x = 17

Answer:

3

Step-by-step explanation:

Firstly, do the numbers inside the absolute value bars.

-6-(-3)

The two negatives that are together turn to a addition sign.

-6+3

You can just subtract 6 and 3 which is 3 and add the - to it.

|-3|

The -3 turns to a 3 since the absolute value bars make all numbers positive within the bars.

Final answer:

By setting up and solving the equation 3x - 4 = 2x + 6, we find that the number in question is 10. This process involves aligning the equation to solve for the variable x, representing the number we seek.

Explanation:

If we multiply a number by 3 and then subtract 4, the result is the same as adding 6 to twice the number. To find this number, we can set up an equation based on the given conditions.

Let's let the number be x. According to the first condition, multiplying x by 3 and then subtracting 4 can be represented as 3x - 4. According to the second condition, adding 6 to twice the number can be represented as 2x + 6.

The two expressions are equal, so our equation is 3x - 4 = 2x + 6.

Subtract 2x from both sides: x - 4 = 6.

Add 4 to both sides: x = 10.

Therefore, the number we are looking for is 10.

Answer:

i think the answer is 1/3 but i'm not positive

Step-by-step explanation:

The slope of a linear line which is passing through the lines  (0,-5), (3, -4) , (6,3) is 1/3. The slope of a straight line is the ratio of y values of two points to the difference in x values of the two points.

In mathematics, slope of a line describes the  steepness or inclination and the direction of the line. Slope of a line is calculated based on the characteristic of the line.

For straight line passing through some points, the x and y coordinates are related by the following expression:

y = mx +c

Where c is the intercept m be the slope.

For a line passing through two points, the slope m is :

m = y2 - y1 / (x2- x1)

Consider the line passing through the points (0, -5) and (3, -4). The slope m = -4 - (-5) / (3 - 0) = 1/3

Similarly if we consider the points (3, -4) and (6, -3)  we get the same slope 1/3.

Step-by-step explanation:

The perimeter of the triangle is 15.4 units.

Step-by-step explanation:

The triangle has vertices at (-1,5), (4,2), and (0,0).

To find the perimeter of the triangle, you need to find the distance of the three points which is the length of the three sides of the triangle.

Let us consider the points as A (-1,5) and B (4,2) and C (0,0).

The distance formula is given by :

⇒ [tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]

Distance of AB :

A (-1,5) ⇒ (x1,y1)

B (4,2) ⇒ (x2,y2)

⇒ [tex]\sqrt{(4+1)^{2}+(2-5)^{2} }[/tex]

⇒ [tex]\sqrt{5^{2}+-3^{2} }[/tex]

⇒ [tex]\sqrt{25+9}[/tex]

⇒ [tex]\sqrt{34}[/tex]

⇒ 5.8

∴ The length of the side AB of the triangle is 5.8 units.

Distance of BC :

B (4,2) ⇒ (x1,y1)

C (0,0) ⇒ (x2,y2)

⇒ [tex]\sqrt{(0-4)^{2}+(0-2)^{2} }[/tex]

⇒ [tex]\sqrt{16+4 }[/tex]

⇒ [tex]\sqrt{20}[/tex]

⇒ 4.5

∴ The length of the side BC of the triangle is 4.5 units.

Distance of CA :

C (0,0) ⇒ (x1,y1)

A (-1,5) ⇒ (x2,y2)

⇒ [tex]\sqrt{(-1-0)^{2}+(5-0)^{2} }[/tex]

⇒ [tex]\sqrt{1+25}[/tex]

⇒ [tex]\sqrt{26}[/tex]

⇒ 5.1

∴ The length of the side CA of the triangle is 5.1 units.

Now, the perimeter of the triangle is given by :

Perimeter = Sum of the lengths of all three sides of the triangle.

⇒ 5.8 + 4.5 + 5.1

⇒ 15.4 units.

∴ The perimeter of the triangle is 15.4 units.
