Step-by-step explanation:

1) if the given sequence is 9;5;1;-3, then a₁=9; a₂=5; a₃=1 and a₄=-3 and

2) the difference is -4.

3) if the difference is -4, then the correct answer is A: aₙ=aₙ₋₁ - 4.

Answer:

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 5/1 so this line "cuts" the y axis at y= 5.00000

y-intercept = 5/1 = 5.00000

Calculate the X-Intercept :

When y = 0 the value of x is 5/7 Our line therefore "cuts" the x axis at x= 0.71429

x-intercept = 5/7 = 0.71429

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 5.000 and for x=2.000, the value of y is -9.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -9.000 - 5.000 = -14.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = -14.000/2.000 = -7.000

Answer:

38*

Step-by-step explanation:

verticle angles are always going to be equivilent so the opposite of x is 38 so x also =38

The measure of angle x from the intersecting lines is x = 28°

Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.

Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.

When lines intersect, two angle relationships are formed:

Opposite angles are congruent

Adjacent angles are supplementary

Given data ,

Let the lines represented by the figure be intersecting lines

And , the missing angle from the first straight line be y

where y = 180° - ( 38° + 90° )

On simplifying , we get

y = 52°

Now , the measure of x is given by

90° + y + x + 10 = 180° ( angles on a straight line )

On simplifying , we get

90 + 52 + 10 + x = 180

Subtracting 152 on both sides , we get

x = 28°

Hence , the measure of angle is x = 28°

PLEASE MARK ME AS BRAINLIEST AND HAVE A NICE DAY

14 omelettes can Kevin make using exactly one of each item.

Multiplication, one of the four basic operations of arithmetic, gives the result of combining groups of equal sizes.

According to the question

Kevin is making an omelette

Types of meat = 7

Types of cheese = 2

Based on the conditions

Number of different omelettes can Kevin make using exactly one of each item = 7 × 2

= 14

Hence, 14 omelettes can Kevin make using exactly one of each item.

Step-by-step explanation:

It takes 8 feet to wrap the small box and 12 feet to wrap the large box

Step-by-step explanation:

The cheerleaders from Campo high school are doing a gift wrapping fundraiser at a clothing store

   Yesterday, they wrapped 36 small clothing boxes and 25 large clothing boxes, using a total of 588 feet of wrapping paper

   The day before, they wrap 27 small clothing boxes and 29 large clothing boxes, using a total of 564 feet of gift wrap

We need to find how much paper it takes to wrap each size of box

Assume that they need x feet to wrap a small box and y feet to wrap a large box

∵ The small box is wrapped by x feet

∵ The large box is wrapped by y feet

∵ They wrapped 36 small clothing boxes and 25 large clothing

  boxes, using a total of 588 feet

∴ 36x + 25y = 588 ⇒ (1)

∵ They wrapped 27 small clothing boxes and 29 large clothing

  boxes, using a total of 564 feet

∴ 27x + 29y = 564 ⇒(2)

Now we have a system of equation to solve it

Multiply equation (1) by -3 and equation (2) by 4 to eliminate x

∵ -108x - 75y = -1764 ⇒ (3)

∵ 108x + 116y = 2256 ⇒ (4)

- Add equations (3) and (4)

∴ 41y = 492

- Divide both sides by 41

∴ y = 12

- Substitute the value of y in equation (1) or (2)

∵ 27x + 29(12) = 564

∴ 27x + 348 = 564

- Subtract 348 from both sides

∴ 27x = 216

- Divide both sides by 27

∴ x = 8

It takes 8 feet to wrap the small box and 12 feet to wrap the large box

Answer:

x = 29 degrees

Step-by-step explanation:

We know that all of the angles inside of a right triangle add up to 180. We also know that a right angle is 90 degrees. We can do 61 + 90 = 151. 180 - 151 = 29. This means that x = 29 degrees.

Answer:

Step-by-step explanation:

the sum of the interior angles in a triangle is 180°

from the picture you have 1 angle of 90° and 1 angle of 61°, sum and you find the "x".

180 - 90 - 61 = 29°

If the ferris wheel has rotated 45 degrees, you will be 50 meters high off the ground

The formula for calculating the circumference of a circle is expressed as:

C = 2πr

where;

If the Ferris wheel has rotated 45°, the height is calculated as:

tan 45 = H/50

H = 50tan 45

H = 50

The height of the ferris wheel off the ground if it has rotated 45° is 12.5π meters

A circle is the locus of a point such that its distance from a fixed point known as the center is always constant.

Given the circumference of the wheel is 100π m.

Since the ferris wheel has rotated 45°, hence:

Height above the ground = (45°/360°) * 100π = 12.5π meters

The height of the ferris wheel off the ground if it has rotated 45° is 12.5π meters
