Step-by-step explanation:

its indirect cause the direct variation would be the y getting bigger with the x, but it's not. It's getting lower when the x is getting higher. hope this helps.

Answer:

Step-by-step explanation:

No because √2 and 3i come in pairs. The four roots are ±√2, 3i and -3i. The 5 guarantees that there are at least 5 roots to this equation. This is a good question to know the answer to. It looks like something that could be put on a test.

Answer:

x = 24

Step-by-step explanation:

48 ÷ 2 = 24 - x

36 ÷ 2 = 18 - y

x = 24

y = 18

Answer:

1a) 67.2 kg

1b) 66.5 kg

1c) 64 kg, 68 kg

2a) Mean = 58.1m, Median = 55m, Mode = 49m

2b) The mode is not a good measure since all data except 49m appeared twice i.e. the data set is quite distributed. (sorry I am not very sure with this answer)

3a) Independent variable is time, Dependent variable is distance.

3b) See attachment.

3c) Linear

3d) 2.5s: 10m 6.25s: 25m 8s: 32m

3e) 3m: 0.75s 21m: 5.25s. 36m: 9s.

Step-by-step explanation:

1a) Mean = (74+71+68+84+54+60+64+68+65+64)/10 kg = 67.2 kg

1b) Sort the data in ascending order (in kg).

54 60 64 64 65 68 68 71 74 84

Median = (65+68)/2 kg = 66.5 kg

1c) Mode = 64 kg, 68 kg (both appeared twice)

2a) Mean = (45+52+47+55+62+80+71+60+84+57+46+50+48+61+49+63+54+49+72)/19 m =  58.1m (correct to 1 decimal place)

Arrange the data in ascending order (in m).

45 46 47 48 49 49 50 52 54 55 57 60 61 62 63 71 72 80 84

Median = 55m

Mode = 49m (appeared twice)

2b) See answer.

3a) Independent variable is the variable that is to be changed. Dependent variable is the variable that is to be measured.

3b) Just plot the graph.

3c) Distance = 4 x time

3d) 2.5 x 4 = 10m. 6.25 x 4 = 25m. 8 x 4 = 32m.

3e) 3/4=0.75s. 21/4=5.25s. 36/4=9s.

h is the missing number in your problem also none as your varabile

9514 1404 393

Answer:

  340 ft^2

Step-by-step explanation:

The length of one side is 1/4 of the perimeter, so is 10 ft.

The area of the base is the square of the length of the side:

  base area = (10 ft)^2 = 100 ft^2

__

The lateral area is the area of four triangles, each with a base of 10 ft and a height of 12 ft.

  lateral area = 4(1/2)(10 ft)(12 ft) = 240 ft^2

__

The total surface area is the sum of the base area and the lateral area:

  surface area = base area + lateral area

  surface area = (100 ft^2) +(240 ft^2) = 340 ft^2

Answer:

infinite

Step-by-step explanation:

y and x can be any numbers because they're independants

Answer:

[tex]\infty[/tex]

Step-by-step explanation:

The domain/range of [tex]x[/tex] or [tex]y[/tex] is not restricted. Therefore, for [tex]x \in \mathrm{R}[/tex], the solutions for [tex]y[/tex] are [tex]\mathrm{R}[/tex] (all real numbers).

Therefore, there are an infinite number of solutions to this equation.

Answer:

A. (2,0)

Step-by-step explanation:

If you graph both of these equations, the two lines will intercept at point (2,0)

Answer:

17 degrees because 180-163=17

Step-by-step explanation:

let the picture be named as above picture:

angle D +163=180 (linear pair)

D=180-163

D=17⁰

Sum of exterior angle of polygon is 360⁰.

148+50+17+90+angleC=360

198+107+angleC=360

305+angleC=360

angleC=360-305

angleC=55⁰

Answer:

9

Step-by-step explanation:

Answer:

Angle 4 is greater, it looks like is a 90 degree angle. so I will say is angle 4

Answer:

Question 11 would be D) 5x - 4y and Question 12 would be A) 7x + 6

Answer:

Cost of shrubs = 23

Cost of tree = 47

Step-by-step explanation:

Let

Cost of shrubs = x

Cost of tree = y

13x + 4y = 487 (1)

6x + 2y = 232 (2)

Multiply (2) by 2

12x + 4y = 464 (3)

13x + 4y = 487 (1)

Subtract (3) from (1)

13x - 12x = 487 - 464

x = 23

Substitute x = 23 into (2)

6x + 2y = 232 (2)

6(23) + 2y = 232

138 + 2y = 232

2y = 232 - 138

2y = 94

y = 94/2

= 47

y = 47

Answer:

I solution; x=8

Step-by-step explanation:

You have to solve for x by simplifying both sides of the equation and then isolating the variable

3(x+2)= 2x+14

Distributive Property

3x+6=2x+14

Isolate the variable

3x+6-6=2x+14-6        which is 3x=2x+8

3x-2x=2x-2x+8

x=8

Answer:

12) The function is linear.

13)  This function is not linear.

Step-by-step explanation:

13) A linear functions equation must be in y = mx + b form

When you graph the table there is no y = mx + b equation that makes a line that passes through all the points.

Answer:

y = 1 3 x + 13 3

Step-by-step explanation:

The equation of the line is  

y = 1 3 x + 13 3

. To find other points on the line, simply plug in an x value, and solve for the corresponding y value.

Explanation:

To find other points on the line, we first have to find the equation for the line. We can easily use point-slope form:  

y − y 1 = m ( x − x 1 )

y − 5 = 1 3 ( x 2 )

To put it in slope-intercept form, isolate y and simplify:

y= 1 3 ( x − 2 ) + 5

y = 1 3 x − 23 + 5

y = 1 3 x + 13 3

Answer:

6 days

Step-by-step explanation:

Given

The proportion can be represented as:

[tex]p = 55\%[/tex]

And the number of days can be represented as:

[tex]n = 10[/tex]

Required

Determine the expected number of times, the light is red

To do this, we simply multiply the proportion by the number of days:

[tex]Y = n * p[/tex]

Substitute values for n and p

[tex]Y = 10 * 55\%[/tex]

Convert percentage to decimal

[tex]Y = 10 * 0.55[/tex]

[tex]Y = 5.5[/tex]

Approximate

[tex]Y = 6[/tex]

Hence, the expected number of days is 6 days

Answer:

110

Step-by-step explanation:

I split the shape into smaller pieces and got 10 for the width and 7 height I multiplied them and got an area of 70 for the first shape. For the second I got the width of 4 and length of 10 multiply them and you'll get 40. Last add them and you get 110 cm.

Answer:

95°

Step-by-step explanation:

Well first draw a parallel to p, let's say r

so we have that

[tex]\angle 2+\angle3=\angle1[/tex]

and

[tex]\angle y=148\\\\\angle x +63=180\\\\\angle x=117[/tex]

so now by internal angles of parallels we know that

[tex]\angle x +\angle 2 = 180\\\\\angle y +\angle 3 = 180[/tex]

which is

[tex]117+\angle 2 = 180\\\\\longrightarrow \angle 2 = 63\\\\148+\angle 3 = 180\\\\\longrightarrow \angle3=32[/tex]

so

[tex]\angle 1 = 63+32\\\\\angle 1 = 95[/tex]

Answer:

I think it's A I'm not sure

Given:

[tex]\tan \theta > 0[/tex] and [tex]\sec \theta <0[/tex].

To find:

The quadrant.

Solution:

We know that,

In I quadrant, all trigonometric ratios are positive.

In II quadrant, only [tex]\sin \theta, \text{cosec}\theta[/tex] are positive and others are negative.

In III quadrant, only [tex]\cot \theta, \tan\theta[/tex] are positive and others are negative.

In IV quadrant, only [tex]\cos \theta, \sec\theta[/tex] are positive and others are negative.

We have,

[tex]\tan \theta > 0[/tex] and [tex]\sec \theta <0[/tex].

Here, [tex]\tan \theta[/tex] is positive and [tex]\sec \theta[/tex] is negative. So, [tex]\theta [/tex] lies in the III quadrant.

Therefore, the correct option is C, i.e., III.
