which of the following lengths cannot be the lengths of a triangle? 4,6,9 a.) 3,4,2 b.) 2,2,3 c.) 1,1,2 d.)

Answer: (X+6)(x-4)

Step-by-step explanation:

x^2-4x+6x-24 ==> x^2+2x-24

*Find two numbers that multiplied gives you -24 and add up to 2*

(6)(-4)= -24          6-4=2

Final result= (x+6)(x-4)

Answer:

-8

Step-by-step explanation:

88=(-x+3)8

88= -8x+24

88-24= -8x

64= - 8x

- x= 64/8

-x=8

x= -8

88 = ( -x + 3) x 8

88 = (3-x) x 8

8= 8 (3-x)

88/8 = 3 - x

11 - 3 = -x

8 = -x

-8 = x

x = -8

Answer:

it is B 70° because if you add 40° + 70° = 110°

so then you need to subtract that from 180°.

180° - 110° = 70°

The measure of angle x is 150 degree.

The definition of "supplementary" in mathematics relates to angles that combine to form a straight angle. It indicates that when two angles sum up to 180 degrees, they are said to be supplementary angles.

As, the angle adjacent to 70° angle

= 180- 70

= 110°

Now, the angle supplement to x

x = 180 - (40+ 110)

x = 180 - 150

x = 30

So, the measure of angle x is 150 degree.

Given:

The coordinate of point R in quadrilateral RUST are (2,4).

R is dilated by a scale factor of 3, centered at the origin, followed by the translation [tex](x, y)\to (x+4,y)[/tex].

To find:

The coordinates of R' after dilation and translation.

Solution:

If a figure is dilated by a scale factor of 3, centered at the origin, then

[tex](x,y)\to (3x,3y)[/tex]

We value R(2,4).

[tex]R(2,4)\to R_1(3(2),3(4))[/tex]

[tex]R(2,4)\to R_1(6,12)[/tex]

The rule of translation is:

[tex](x, y)\to (x+4,y)[/tex]

Using this rule, we get

[tex]R_1(6,12)\to R'(6+4,12)[/tex]

[tex]R_1(6,12)\to R'(10,12)[/tex]

Therefore, the coordinates of point R' are (10,12) and the correct option is B.

Answer:

34.99°

Step-by-step explanation:

CHECK THE ATTACHMENT FOR THE FIQURE

Let angle( X) = angle if elevation

From trigonometry, tan(X)= opposite/ adjacent

Height of the flagpole= 21 ft , which is the opposite side

The base, adjacent side = 30 ft

If we substitute the values we have

Tan(X) = 21/30

Tan(X)= 0.7

Tan-1(0.7)=34.99°

Hence, the angle of elevation of the sun when this shadow will cast is 34.99°

Question

Find the perimeter of a triangle with vertices A(2,5) B(2,-2) C(5,-2). Round your answer to the nearest tenth and show your work.​

perimeter of a triangle = AB+AC+BC

Using the distance formula

AB = sqrt(-2-5)²+(2-2)²

AB = sqrt(-7)²

AB =sqrt(49)

AB =7

BC = sqrt(-2+2)²+(2-5)²

BC = sqrt(0+3²)

BC =sqrt(9)

BC =3

AC= sqrt(-2-5)²+(2-5)²

AC= sqrt(-7)²+3²

AC =sqrt(49+9)

AC =sqrt58

Perimeter = 10+sqrt58

the answer is yes. Why? Because if you move a vertical line across the graph, at any given moment, it only touches one point. If it touched more than one point it wouldn't be a function.

Answer:

A. $2.25

Step-by-step explanation:

If you subtract $7.50 from $18.75 you get $11.25, then divide that by 5 and you'll get $2.25.

Hope this was useful.

Answer:

The answer would be $2.25

Step-by-step explanation:

If you multiply 2.25 with 5 you get 11.25 so now you just add the 7.50 to it and that's how you get 18.75

The recursive formula for g(n) is:

g(1) = -72 (base case)

g(n) = [tex]g(n-1) \times (-1/6)[/tex] (for n > 1)

A recursive formula is a formula that defines a sequence or function by expressing each term in terms of one or more previous terms.

It is a way of defining a sequence or function iteratively, where each term or value depends on the previous terms or values.

To find the recursive formula for [tex]g(n) = -72\times (1/6)^{(n-1)} ,[/tex]   we need to express the function in terms of its previous term, g(n-1).

Notice that g(n) can be obtained by multiplying g(n-1) by -1/6.

This is because:

[tex]g(n) = -72\times (1/6)^{(n-1)}[/tex]

[tex]g(n-1) = -72\times (1/6)^{(n-2) }[/tex]

So we can write:

[tex]g(n) = g(n-1) \times {(-1/6) }[/tex]
