Answer:

The ages of the four siblings are: 5, 7, 9 and 11 years old.

Step-by-step explanation:

The computation of the age of the four siblings is shown below:

Given that

n = 4

a1 =? a2 =? a3 =? a4 =?

a4 = a1 + 6 years

S4 = 32

Based on the above information

As we know that

Sn = (a1 + a4) ×  n ÷ 2

S4 = (a1 + a4) × 4 ÷ 2

32 = (a1 + a1 +6) × 2

16 = 2a1 + 6

 2a1 = 10

 a1 = 10 ÷ 2

= 5

So,  a4 = a1 +6

= 5 +6

= 11

a4 = a1 + (4-1) × d

11 = 5 + 3 × d

d = 6 ÷ 3

= 2

So,

a2 = a1 + d

= 5 + 2

= 7

a3 = a2 + d

= 7 + 2

= 9

Hence, The ages of the four siblings are: 5, 7, 9 and 11 years old.

Answer:

Is the dilation an enlargement or reduction?

Reduction

The point of dilation is about what coordinate?

0,0

What is the scale factor?

1/3

Step-by-step explanation:

The dilation is a reduction. The point of dilation is about coordinate (0,0).  The scale factor is 1/3.

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

On a coordinate plane, the pre-image rectangle has points (0, 0), (6, 0), (6, -3), and (0, -3).

The image has points (0, 0), (2, 0), (2, -1), and (0, -1).

The required figure has been attached below which represents the dilation.

As we can see that the dilation is a reduction.

The point of dilation is about coordinate (0,0).

This result of dilating a given triangle with a scale factor is 1/3.

Answer:

I believe it might be B

if I'm wrong I apologise.

Answer:

I believe the answer for this would actually not be B, but C.

Step-by-step explanation:

C is an exponential function, exponential functions are known for increasing at the fastest rate for larger values of X. Here is a picture of my Algebra reading material if this helps better explain it.

Answer:

[tex]y=-2\\[/tex]

Step-by-step explanation:

Use the values of the unit circle to get the (x,y) when Θ=[tex]\frac{11\pi}{6}[/tex], which is [tex](\frac{\sqrt{3}}{2}, -\frac{1}{2})[/tex].

The cosecant (csc) function is the reciprocal of the sine function, so we take the y value and take the reciprocal of it, which is -2.

Answer:

earthworm

Step-by-step explanation:

The worm which hasbristles, called setae, on its soft body to help it move is roundworm, the correct option is roundworm.

Worms are described as many different distantly related bilateral animals that typically have a long cylindrical tube-like body, no limbs, and no eyes. Roundworms constitutes of the phylum Nematoda, with plant-parasitic nematodes also known as eelworms.

Given;

The worms has bristles, called setae

Now,

Roundworm infections usually occur when soil, sand, or plants that have been contaminated with infected animal feces are accidentally put in the mouth and ingested by individuals;

Therefore, the worm will be roundworm.

Answer:

  y = 3/4x -7/4  or  y = 0.75x -1.75

Step-by-step explanation:

The two point form of the equation of a line is useful when you are given 2 points and asked for the equation.

  y = (y2 -y1)/(x2 -x1)·(x -x1) +y1

  y = (35 -14)/(49 -21)·(x -21) +14 . . . . . . fill in given points

  y = 21/28(x -21) +14 . . . . . . . . . . . . . . . simplify a bit

  y = 3/4(x -21) +14 . . . . . . . . . . . reduce the fraction

  y = 3/4x -15 3/4 +14 . . . . . . . .eliminate parentheses

  y = 3/4x -7/4  or  y = 0.75x -1.75

Answer:

Step-by-step explanation:

The inequality can be seen graphed in the number line that I have created in the attached picture below. As you can see the open circle represents the value 1 1/4 and is an open circle because it is not included in the inequality. This is because the variable z is less than but NOT equal to 1 1/4. Also since z is any number less than 1 1/4 then the number line goes towards negative infinity.

Answer:45 Don't take the answer might be wrong

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

-8x + y = -3..... (equ 1)

9x - y = 3.....(equ2)

y = 8x - 3

-y = -9x + 3(divide both sides by -1*)

hence ..y = 9x - 3

then write y = y in terms of x

which will give you 8x - 3 = 9x - 3

and solve for x which will be N/A

A. y=6x-3

B. The slope is 6

C. y-intercept is -3

E. y-6x= -3

F. (1/2, 0)

Step-by-step explanation:

I can't do the graph because I don't know how to input a picture but I hope this helped!

This is for the second half of the page:

2. the slope of y=3 is 0 so m=0

to graph just draw a line horizontally at 3

3. the equation of the line is x=2

the slope of this line undefined, so literally just write undefined

What angle should a ramp be?

Maximum slope for hand-propelled wheelchair ramps should be 1" of rise to every 12" of length (4.8 degree angle; 8.3% grade). Maximum slope for power chairs should be 1.5" rise to 12" length (7.1 degree angle; 12.5% grade). Minimum width should be 36" (inside rails) - (48" is ideal)
