Answer: 53

Step-by-step explanation:

Answer:

53

Step-by-step explanation:

Part (a)

This sequence is arithmetic because we are adding 4 to each term to get the next term. Nice work on getting the correct answer here.

To get the nth term of an arithmetic sequence, we'll use the formula below

an = a + d(n-1)

In this case, a = 14 is the first term and d = 4 is the common difference

So we have these steps

an = a + d(n-1)

an = 14 + 4(n-1)

an = 14 + 4n - 4

an = 4n + 10

Answer: 4n + 10

============================================

Part (b)

This sequence is geometric since we multiply each term by 4

The common ratio is r = 4 and the start term is a = 2.

So the nth term is....

an = a*(r)^(n-1)

an = 2*(4)^(n-1)

Answer: 2*(4)^(n-1)

7 is 1/10 of 70. You can figure this out by multiplying 7 by 10

Answer:

A. (x, y) -> (0.2x, 0.2y)

Step-by-step explanation:

I'll test this out with just point S if that's fine.

Point S's coordinates are (5, -5), as seen on the coordinate plane.

However,  Point S' has coordinates of (1, -1).

Divide 1 by 5 to get 1/5. You can also do -1/-5 to also get 1/5 (Remember, dividing two negatives gets you a positive.).

So you can conclude that the dilation has the x and y coordinates shrinking to 1/5 of the original. Both coordinates shrink at the same rate, so B and C are out. The figure is NOT getting bigger so D is also incorrect. This leaves A ((x, y) -> (0.2x, 0.2y)) as our answer.

Answer:

The bike will cost $481.50

because

10% off of 500 is 50

so 500 - 50 = 450

Now include the sales tax which is

450 * 0.07 = 31.5

Now add the two totals to get

$481.50

Answer:

141

Step-by-step explanation:

Answer:

141

Step-by-step explanation:

Find the third angle in the triangle and using the rule that all supplementarly angles are 180 degrees, subtract the third angle from 180.

180-87-54=39, 39 is the third angle of the triangle

180-39=141 degrees, x= 141

Answer:

can you pls show more......

Step-by-step explanation:

Step-by-step explanation:

The pre-image points are A( 0,0 ), B(2, 0) and C(0, 4). The question is asking you to rotate the traingle 180°. Each rotation has its rules. For 180° rotation our rule is (x,y) → (-x,-y). Let's apply that to our points:

A( 0,0 ), → (0,0)

B(2, 0) → (-2,0)

and C(0, 4). → (0,-4)

Now we dilate our point ( remember the order in which you do transformation is important. Since it saids the rotation is followed that means the dilation is done second)

Our scale factor is 3. Remember when our scale factor is more than one our shape gets bigger. So our rule is (x,y) → (kx,ky). Let's apply our scale factor to all our points:

(0,0) → (0,0)

(-2,0)→( -6,0)

(0,-4) → (0,-12)

The answer is

A' (0,0) B' (-6,0) C' (0,-12)

The triangles will be similar not congruent. Remember congruent triangles have the same angles and same sizes. Similar angles have the same angles BUT different sizes. Every transformation produces congruent angles except for dilations.

The values of x and y that make the quadrilateral a parallelogram​ are, X = 25 & Y = 15

Quadrilateral are the type of polygon who has 4 sides, on the basis of length and angle between sides we can further classify quadrilateral into following categories;

for example, Rectangle, Square, Parallelogram, Rhombus, Trapezium

Given that,

A parallelogram whose all the angles are,

(4x + 13)°, (4y + 7)°, (3x - 8)°, (5x - 12)°

It is known that,

Opposite Interior angles of  parallelogram are equal

so,

⇒ (4x + 13) = (5x - 12)

⇒  x = 25

⇒  (4y + 7) = (3x - 8)

⇒   4y + 7  = 75 - 8

⇒   4y = 60

⇒    y = 15

Hence, the values of x and y are respectively 25, 15

Answer:

Option - b: 60

Step-by-step explanation:

Sum of exterior angle = 360

Exterior angle = 60

6x = 360

x = 360 / 6 = 60

Answer:

A = $150

B = $130

C = $140

Step-by-step explanation:

Let the amount received by a be $x

b receives $20 less than a;

we have that;

b = x - 20

c receives half of Sum A and B

c = (x + x-20)/2

c = (2x-20)/2

c = x - 10

Add all and it gives 420

x - 10 + x -20 + x = 420

3x -30 = 420

3x = 420 + 30

3x = 450

x = 450/3

x =$150

a = 150

b = x - 20; 150 - 20 = 130

c = x-10

c = 150-10

c = $140

Step-by-step explanation:

the Pythagorean theorem is

c is the hypotenuse which is the side opposite of the right angle

plug the numbers into the Pythagorean theorem

[tex]x^2+(\sqrt{26})^2=13^2[/tex]

when squaring a square root, just take the number in the radical and get rid of the radical

[tex]x^2+26=169[/tex]

subtract 26 from both sides

[tex]x^2=[/tex][tex]143[/tex]

find the square root of 143
