What is the value of the following expression if x = 22: "five times a number x,
decreased by 2"?​

Answer:

Step-by-step explanation:

\[a_{n}=a{1}r^{n-1}\]

r=16/8=2

a_{12}=8(2)^{12-1}

[tex]a_{12}=8(2)^{11}=16384[/tex]  

The 12th term of the geometric sequence is 16384.

An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference

d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.

In a geometric sequence numbers are written in the same common ratio(r).

It means every next number is a multiple of a common constant and the previous number.

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

Given, a geometric sequence  8, 16, 32,... which has a common ratio(r)

= 16/8 and first term a₁ = 8.

We know nth term of a geometric sequence is aₙ = a₁rⁿ⁻¹.

∴ 12t term of the geometric sequence is a₁₂ = 8.2¹²⁻¹

=  8.2¹¹.

= 8.2048.

= 16384.

Answer:

number five: 37.065 number six 241

Step-by-step explanation:

FOR NUMBER FIVE:

so for the rectangles, the formula is L * W.   L for length W for width

so 5×3 = 15. and there are 2 rectangles with the same measurment so its

15 + 15 which is 30 (for both rectangles)

and for the circle formula its pi r^2 where pi is 3.14 and r is radius

so 3.14 × 3^2 = 28.26. but since its a quarter of a circle, divide it by four which is 7.065.

so 30 + 7.065 = 37.065

FOR NUMBER SIX:

the area of a triangle formula is b * h ÷ 2 where b is base and h is height

so its 22 * 8 / 2 = 88

and for the trapezoid the formula is [tex]\frac{a+b}{2} h[/tex] where a and b are the bases and h is height

so its[tex]\frac{12+22}{2} *9[/tex] = 153

88+153= 241

Answer: 1/9

Step-by-step explanation:

You have 3 possible options. The probablility of the spinner landing on 3 is 1/3. The probability of it landing on 2 is also 1/3. For them to happen together, you multiply them. 1/3 * 1/3 = 1/9.

The probability of landing on a 3 and then landing on a 2 is,

⇒ 1/9

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one

Given that;

You spin the spinner twice.

Now, The probability of the spinner landing on 3 is,

⇒ 1/3.

And, The probability of it landing on 2 is,

⇒ 1/3.

Hence, The probability of landing on a 3 and then landing on a 2 is,

⇒ 1/3 × 1/3

⇒ 1/9.

Step-by-step explanation:

Because if you subtract one of the constants from both sides then you should only have equal variables. In other words, both sides have to be identical in this situation.

33x-33= 33x + 25

33x = 33x + 58 No matter what you make x, the right will be 58 bigger than the right so there is no solution.

33x+33=33x+25

33x+8= 33x nope no solution

33x+25=33x+25

33x = 33x both sides identical so there is a solution

33x-25 = 33x +25

33x= 33x+50

Answer:

6.06cm

Step-by-step explanation:

An equilateral triangle is a triangle that has all its sides equal. If the given  equilateral triangle has a side length of 7 cm, then all its sides are 7cm each. To get the length of the perpendicular dropped from a corner. we will use the Pythagoras theorem.

According to the theorem,

hyp² = opp²+adj²

Lets take the height as the opposite side of one of the right angled triangle as shown in the attachment.

hyp = 7cm and adj = 7/2 = 3.5cm

opp² = 7² - 3.5²

opp² = 49 - 12.25

Opp = √36.75

Opp = 6.06cm

This shows that the length of the perpendicular is 6.06m
