The square root of 144 is ± 12

The correct answer choice is option C.

Square root refers to a number which, when squared, yields another number.

For instance, the square root of 4 is ± 2

the square root of 9 is ± 3

the square root of 16 is ± 4

the square root of 25 is ± 5

Therefore, square root of 144 = ±12

that is, (12 × 12) or (-12 × -12)

Answer:

Multiply be 3 each time

Step-by-step explanation:

4*3=12

12*3=36

36*3=108

108*3=324

Answer:

A

Step-by-step explanation:

The base angles L and N are congruent.

Thus the triangle is isosceles and ML = MN, that is

3x = x + 8 ( subtract x from both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Thus

MN = x + 8 = 4 + 8 = 12 → A

Answer:

Interest = $60.75

Amount = $510.75

Step-by-step explanation:

The formula for finding interest is;

Interest = Principal * Rate * Time

And here;

Principal = $450

Rate = 41/2% or 4.5%

Time = 3 years

Interest = [tex]\frac{450 * 45 * 3}{1000}[/tex]

Divided by 100 because of the percentage of the rate but here I made it 1000 because I moved the decimal point in the 4.5 forward once which means I have to add 0 to the denominator.

              = [tex]\frac{45*45*3}{100}[/tex]

             = [tex]\frac{6075}{100}[/tex]

            = $60.75

Now the amount is simply the Principal + Interest which will be;

= $450 + $60.75

= $510.75

Answer:

Option C

Step-by-step explanation:

Consider the function f ( x ) = 3x^2 + 4;

[tex]f ( x ) = 3x^2 + 4,\\\\4 = vertex ( y - intercept ),\\\\\\[/tex]

Now if this graph were to be translated 7 units down, considering the function was f ( x ) = 3x^2, the new graph would be f ( x ) = 3x^2 - 7. The same concept is applied to the graph f ( x ) = 3x^2 + 4;

[tex]4 - 7 = - 3,\\f ( x ) = 3x^2 - 3\\\\Solution - Option C[/tex]

* Note that a translation doesn't effect the rate with which the graph changes, it only effect's it's position on the coordinate plane

The  recursive formula for the given sequence

                 [tex]t_{n}= (2)^{n+2}[/tex]

Step-by-step explanation:

Explanation:-

Given sequence is 8 , 16, 32, 64 ,.....

First term is   a = 8

common ratio   [tex]r = \frac{16}{8} =2[/tex]

                       [tex]r = \frac{32}{16} =2[/tex]

                      [tex]r = \frac{64}{32} =2[/tex]   and so on..

Given sequence of the common ratio 'r' is equal

The [tex]n^{th}[/tex] term of the sequence

                   [tex]t_{n} = a r^{n-1}[/tex]

                   [tex]t_{n}= 8 (2)^{n-1}[/tex]

                   [tex]t_{n}= (2)^{(3+n-1)}[/tex]

This is  recursive formula for the given sequence

                 [tex]t_{n}= (2)^{n+2}[/tex]

Verification:-

           [tex]t_{n}= (2)^{n+2}[/tex]

put n=1   ⇒ t₁ = 8

put n=2   ⇒ t₂ = 16

put n=3   ⇒ t₃ = 32

put n=4   ⇒ t₄= 64

Answer:

1/26

Step-by-step explanation:

In a standard pack of cards, there are 52 total cards and 4 aces, two black aces and two red aces.

The probability of selecting an ace is therefore:

4/52 = 1/13

The probability of flipping a coin and it landing on tails is:

1/2

Therefore, the probability of selecting an Ace and the coin landing on tails is:

1/13 * 1/2 = 1/26

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question.

"Mr. Anderson cuts a piece of metal in the shape of the triangle shown. The piece of metal has an area of 7 1/2 square feet. What is the base of the piece of metal? triangle 5ft high"

Area of the triangle = 1/2 * base * height

Given the area of the piece metal = 7 1/2 ft² and its height = 5ft (since the triangle is 5ft high). On substituting the values in the formula;

7 1/2 = 1/2* base * 5

15/2 = 5/2 * base

15 = 5 * base

base = 15/5

base = 3ft

The base of the piece of metal is 3ft

Answer:

14.5 =x

Step-by-step explanation:

Since this is a right triangle we can use trig functions

sin theta = opposite side/ hypotenuse

sin A = BC / AB

sin 65 = x /16

Multiply each side by 16

16 sin 65 =x

14.50092459 =x

14.5 =x

Answer:

C on edge

Step-by-step explanation:

Answer:

a) y = 5x

b) y = 60

Step-by-step explanation:

y ∝ x

So, y = kx      -----(1)

Where k is the constant of proportionality

Now, y = 30, x = 6

Putting in (1)

30 = k(6)

Dividing both sides by 6, we get

k = 5

Now, Putting k=5 in (1)

So,

a) The equation connecting x and y is :

y = 5x

b) x = 12, Putting in (1)

y = (5)(12)

y = 60

Answer:

a)y=5x

b)60

Step-by-step explanation:

Answer:

y=84

first : 84+13=97

second : 84+15=99

third : 84+23=107

fourth: 84+29=113

fifth : 84+40 =124

97+99+107+113+124 = 540

Step-by-step explanation:

sum of interior angles of a pentagon=540 degreas

y+13+y+15+y+23+y+29+y+40=540

5y=540-(13+15+23+29+40)

y=84

first : 84+13=97

second : 84+15=99

third : 84+23=107

fourth: 84+29=113

fifth : 84+40 =124

97+99+107+113+124 = 540

Answer:

Equation 5 + 2(3 + 2x) = x + 3(x + 1) has no solution.

Step-by-step explanation:

We are looking at two lines.

4(x + 3) + 2x = 6(x +2)

4x + 12 + 2x = 6x + 12

6x + 12 = 6x + 12

These are two identical lines, with an infinite number of solutions. (All points on the lines are the exactly the same).

5 + 2(3 + 2x) = x + 3(x + 1)

5 + 6 + 4x = x + 3x + 3

4x + 11 = 4x + 3

Both lines have the same gradient but have a different incline with the y axis. By definition, they are parallel to each other and there fore have zero solutions. Equation 5 + 2(3 + 2x) = x + 3(x + 1) has no solution, which is the answer we are looking for.

5(x + 3) + x = 4(x +3) + 3

5x + 15 + x = 4x + 12 + 3

6x + 15 = 4x + 15

These are two different lines with exactly one solution.

4 + 6(2 + x) = 2(3x + 8)

4 + 12 + 6x = 6x + 16

6x + 16 = 6x + 16

These are two identical lines, with an infinite number of solutions. (All points on the lines are the exactly the same).

Answer:

the coordinates of y are (1,-4)

Step-by-step explanation:

by using midpoint formula

z(x,y)=([tex]\frac{x1+x2}{2}[/tex],[tex]\frac{y1+y2}{2}[/tex])

putting the values of coordinates

(3,-1)=[tex]\frac{5+a}{2}[/tex],[tex]\frac{2+b}{2}[/tex]

separating the coordinates

3=[tex]\frac{5+a}{2}[/tex]                and           -1=[tex]\frac{2+b}{2}[/tex]

3×2=5+a                and      -1×2=2+b

6=5+a                  and        -2=2+b

6-5=a                    and          -2-2=b

1=a                            and            -4=b

so the actual coordinates of y are (1,-4)

Answer:

x = -5 or x = -4/3

Step-by-step explanation:

First possibility.

|2x − 1| = |4x + 9|

2x - 1 = 4x + 9

2x - 4x = 9 + 1

-2x = 10

x = 10/-2

x = -5

Second possibility.

2x - 1 = - (4x+9)

2x - 1 = -4x - 9

2x + 4x = -9 + 1

6x = -8

x = -8/6

x = -4/3

Answer:

[tex] |2x - 1| = |4x + 9| [/tex]

this equation can be separated into 2 possible cases :

[tex]2x - 1 = 4x + 9[/tex]

and

[tex]2x - 1 = - (4x + 9)[/tex]

solve the 1st possible case:

[tex]2x - 1 = 4x + 9[/tex]

[tex]2x - 4x = 9 + 1[/tex]

[tex] - 2x = 10[/tex]

[tex]x = - \frac{10}{2} [/tex]

[tex]x = - 5[/tex]

solve the 2nd possible case:

[tex]2x - 1 = - (4x + 9)[/tex]

[tex]2x - 1 = - 4x - 9[/tex]

[tex]2x + 4x = - 9 + 1[/tex]

[tex]6x = - 8[/tex]

[tex]x = \frac{ - 8}{6} [/tex]

[tex]x = - \frac{4}{3} [/tex]

so the x value for this equation is:

x = -5 or x = -1.333
