Answer:a

Step-by-step explanation:

Answer:

y = (10/9)x - 138/9

Height of 164.7 cm for an arm span of 162 cm

Step-by-step explanation:

First we find the slope.  (178 - 168)/(174 - 165) = 10/9

Now use the point-slope form of a line

y - 168 = 10/9(x - 165)

9y - 9(168) = 10(x - 165)

9y - 1512 = 10x - 1650

9y = 10x - 138

y = (10/9)x - 138/9

If the arm span is 162 cm, then x = 162

y = (10/9)(162) -138/9

= 180 - 15.3

 = 164.7 cm

Step-by-step explanation:

Answer:

x° = 77.7°

Step-by-step explanation:

We know that the interior angles within a quadrilateral add up to 360 degrees. We are provided with two right angles and a third angle of 102.3°. So we must solve to find x.

90 + 90 = 180

102.3 + 180 = 282.3

360 - 282.3 = 77.7

x = 77.7 degrees

Answer:

8 bags

Step-by-step explanation:

If 5 bags equal 35 kg, then each bag will weigh 35/5 or 7 kg. If there are 56 kg and you want to find the number of bags, you divide 56 by 7 and you get 8.

Answer:

B

Step-by-step explanation:

cos(35)=x/15  

15cos(35)=x

x=12.3

A≈907.92in²

Because:

A=πr2=π·172≈907.92028in²

Answer:

289π or 907.46 in

Step-by-step explanation:

The formula for area of a circle is π r².

The radius is 17, so the first step is 17².

17²= 289

Next, you multiply 289 by pi (3.14).

3.14 x 289 = 907.46.

Therefore, the area in terms of pi is 289π or 907.46 in.

Answer:

Domain : [tex]0 \le x \le 8[/tex]

Range : [tex]5450 \le f(x) \le 6588.65[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 5450(1.024)^x[/tex]

Required

Domain: [tex][\ ] \le x\ [\ ][/tex]

Range: [tex][\ ] \le f(x)\ [\ ][/tex]

See attachment for complete question

Calculating the domain:

At the instance when she keeps the money in the college fund;

[tex]x = 0[/tex] ---- 0 years

She plans to wait till the 8th year.

[tex]x = 8[/tex]

Hence, the domain is:

[tex]0 \le x \le 8[/tex]

Calculating the range:

We have:

[tex]f(x) = 5450(1.024)^x[/tex]

When: [tex]x = 0[/tex]

[tex]f(0) = 5450 * 1.024^0[/tex]

[tex]f(0) = 5450 * 1[/tex]

[tex]f(0) = 5450[/tex]

When [tex]x = 8[/tex]

[tex]f(8)=5450 * 1.024^8[/tex]

[tex]f(8)=6588.65[/tex]

Hence, the range is: [tex]5450 \le f(x) \le 6588.65[/tex]

Answer:

domain-   [tex]0\leq x \leq 8\\\\[/tex]

range-  [tex]5450\leq f(x)\leq 6588.65[/tex]

Answer:

Not linear

Step-by-step explanation:

This equation does not have a set slope.

Answer:

Trapezoid area:

A = 1/2(4 + 8)*8 = 48 units²

A = 1/2(4 + 10)*6 = 42 units²

A = 1/2(6 + 10)*8 = 64 units²

Area of trapezoid:

Line RS: 2x2 = 4 units (first base)

Line TA: 4x2 = 8 units (second base)

The height (aka that x-axis inside shape): 4x2 = 8 units (h)

Area formula: (4 + 8)8 ÷ 2

= (4 + 8)8 ÷ 2

= 12(8) ÷ 2

= 96 ÷ 2

ANSWER = 48 sq. units

____________________________________________________________

Area of trapezoid:

Line SK: 2x2 = 4 units (first base)

Line OC: 5x2 = 10 units (second base)

Line SO (height): 3x2 = 6 units (h)

Area formula: (b1 + b2)h ÷ 2

= (4 + 10)6 ÷ 2

= 14(6) ÷ 2

= 84 ÷ 2

ANSWER = 42 sq. units

____________________________________________________________

Area of trapezoid:

Line ME: 6 units (first base)

Line AZ: 10 units (second base)

Line MA (height): 8 units (h)

Area formula: (b1 + b2)h ÷ 2

= (6 + 10)8 ÷ 2

= (16)8 ÷ 2

= 128 ÷ 2

= 64

ANSWER = 64 sq. units

Answer:

x = 36°

m<1 = 36°

m<2 = 144°

m<3 = 36°

m<4 = 144°

m<5 = 144°

m<6 = 36°

Step-by-step explanation:

✔️x° + 4x° = 180° (linear angle pair theorem)

5x = 180

x = 180/5

x = 36°

For easy identification, the six angles to be found have been labelled <1 to <6 as shown in the attachment below.

✔️m<1 = x° (vertical angles pair)

m<1 = 36° (substitution)

✔️m<2 = 4x° (vertical angles pair)

Plug in the value of x

m<2 = 4(36)

m<2 = 144°

✔️m<3 = x° (alternate interior angles theorem)

m<3 = 36° (substitution)

✔️m<4 = 4x° (corresponding angles theorem)

m<4 = 4(36) (substitution)

m<4 = 144°

✔️m<5 = 4x° (alternate exterior angles theorem)

m<5 = 4(36)

m<5 = 144°

✔️m<6 = x° (corresponding angles theorem)

m<6 = 36°

Answer:

m<C can not be computed

Step-by-step explanation:

m∠A = 50°, c = 25, a = 19, m∠C=?

Using the Sine Law

a/sin m<A = c/sin m<C

Substitute the given values

19/sin50 = 25/sinC

19sinC = 25sin50

19sinC = 19.1511

sinC = 19.1511/19

sinC = 1.0079

C =  arcsin1.0079

Hence m<C can not be computed

the volume of the rectangular prism is 90 cm^2

Step-by-step explanation:

The computation of the volume of the rectangular prism is shown below:

Given that

The volume in a single layer is 18 cubic centimeters

And, there are 5 layers in the rectangular prism

So based on the above information

The volume of the rectangular prism is

= 5 ×18 cubic centimeters

= 90 cm^2

Hence, the volume of the rectangular prism is 90 cm^2

i is a good game and a good idea but it needs more people who are not the only ones that they were playing in a few weeks ago i dont have a game on joke

Given:

The equation is:

[tex]\dfrac{7}{3}+x=3[/tex]

To find:

The value of x.

Solution:

We have,

[tex]\dfrac{7}{3}+x=3[/tex]

Subtract both sides by [tex]\dfrac{7}{3}[/tex].

[tex]\dfrac{7}{3}+x-\dfrac{7}{3}=3-\dfrac{7}{3}[/tex]

[tex]x=\dfrac{9-7}{3}[/tex]

[tex]x=\dfrac{2}{3}[/tex]

Therefore, the value of x is [tex]\dfrac{2}{3}[/tex] or it can be written as 0.667.

C. X-2/X+3

Step-by-step explanation:

(4/x) + (4/y) / (16/x2y2) is where we start. I will factor out

1/(16/x2y2).

(1/(16/x2y2)) (64xy2 + 4/y) = (x2y2/16)(64xy2 + 4/y)

I need to factor out a 4/y from there.

(x2y/4)(16xy + 1) = x2y (16xy + 1) / 4

Answer:

Step-by-step explanation:

x = 77°/ 11

x = 7°

Answer:

The correct option is;

The fourth option

Please the attached drawing created with MS Visio

Step-by-step explanation:

From the given figure, we have;

The orientation of ΔSTU is equal to the orientation of ΔS'T'U'

When the plane of reflection is assumed to be the y-axis, we have;

For a reflection about the y-axis, we have;

The coordinate of the preimage = (x, y)

The coordinate of the image after the reflection = (-x, y)

When the image (-x, y) is reflected again across the y-axis, and becomes the image, we have;

The coordinate of the preimage = (-x, y)

The coordinate of the image after the reflection = (x, y)

Therefore, a reflection twice across the same y-axis would result in an image having the same orientation as the preimage

Given that a y-axis is parallel to another y-axis, we have;

A reflection twice across two parallel axis would result in an image having the same orientation as the preimage

The correct option is the 4th option

Please see attached drawing created with MS Visio

Answer:

the fourth one

Step-by-step explanation:

The pre-image and image of the translation are given.

To find the lines of reflection, locate a midpoint M of the translation vector between any two corresponding points on the pre-image and image.

The figure shows two congruent triangles S T U and S prime T prime U prime.

Then find the midpoints of SM and MS'.

The figure shows the same triangles S T U and S prime T prime U prime as in the previous figure. Point K is a midpoint of segment M S. Point N is a midpoint of segment M S prime.

The lines of reflection are perpendicular to the vector and intersect with the vector at the second set of midpoints by the Theorem of composition of two reflections across two parallel lines.

The figure shows the same triangles S T U and S prime T prime U prime as in the previous figure. There are two lines. The first line passes through point K. The second line passes through point N. These lines are perpendicular to segment S, S prime.

Therefore, the correct graph is the fourth one.

Answer:

y=1; x=2

Step-by-step explanation:

Substitution:

x=2y

2x+5y=9

=> if x=2y, plug in the x value into other equation, so

----------------------------------------------------------------------------

2(2y)+5y=9

4y+5y=9

9y=9

y=1

You have the Y value, so now solve for X

-----------------------------------------------------------------------

plug in y value to x=2y

so x=2(1)

x=2
