How many degrees is 1.2 rotations counter clockwise?

Step-by-step explanation:

x²+3x+4=0

x²+3x_ +2=0

x²+3x_2=-2

x²+3x_2+(3x_4)²=-2+(3/4)²

(x+3/4) =-2+9_16

x+3_4 = -32+9__16 =√-23_6

x+3_4 =-√23_4

x = -3+√-23___4

x = -3- √-23___4 , -3+√-23___4 //

Answer:

90

Step-by-step explanation:

The angle of AEB is 90 degrees, took the test and got it correct!

The measure of m<AEB is 90 degrees

From the given square, the triangle AEB is a right triangle.

m<AEB = 180 - (45+45)

m<AEB = 180 - 90

m<AEB = 90 degrees

Hence the measure of m<AEB is 90 degrees

Answer:

Step-by-step explanation:

therefore

[tex]r = \frac{3 \frac{1}{4} }{2} [/tex]

[tex]r = \frac{ \frac{13}{2} }{2} [/tex]

[tex]r = \frac{13}{2} \div 2[/tex]

[tex]r = \frac{13}{4} [/tex]

[tex]area \: of \: a \: circle \: = \pi {r}^{2} [/tex]

Diameter of the stained glass window Joey needs = 3.5

Area of the window = quantity of glass Joey needs

Area of the window :

[tex] = \tt\pi {r}^{2} [/tex]

[tex] = \tt3.14 \times 3.5 \times 3.5[/tex]

[tex] =\tt 3.14 \times 12.25[/tex]

[tex] =\tt 38.46[/tex]

38.46 can be rounded off to 38.5.

Therefore, quantity of glass needed to make the stained glass window = 38.5

Answer:

The numbers are  x= 9 and y =6

The product of two numbers

x y  = 9 × 6 = 54

Step-by-step explanation:

Step(i):-

Let x and y are two numbers

Given that the sum of two numbers

 x + y = 15 ..(i)

Given that the difference of two numbers

x - y = 3 ..(ii)

adding (i) and (ii) , we get

x + y + x -y = 15 +3

  2 x = 18

    x =9

Step(ii):-

Substitute x = 9 in equation (i) , we get

x + y = 15

9 + y = 15

     y = 15 - 9

    y = 6

Final answer:-

The numbers are  x= 9 and y =6

The product of two numbers

x y  = 9 × 6 = 54

Answer:

C

Step-by-step explanation:

First find the radius:

5 pi = 2 pi r

cancel out pi

5 = 2r

r = 5/2

Then find the area:

A = pi r^2

A = pi 5/2^2

A = 25/4 pi

Answer:

n= -9, t= -9

Step-by-step explanation:

1) -1/3(n+15)=-2

-1/3×n+-1/3×15=-2

-1/3×n -5= -2

-1/3 n-5+5= -2+5

-1/3×n=3

3/-1×-1/3×n=3/-1×3

n= -9

2) 46 = -6t -8

−6t−8=46

−6t−8+8=46+8

−6t=54

Divide both sides by -6

t=-9

Answer:

The first one

Step-by-step explanation:

The amplitude is usually the first number (for example, in this equation, the 3). Then you also know that the right or left shift depends on the addition or subtraction sign. Usually, the subtraction sign means to the right and the addition sign means to the left.

We have that the graph of which function has an amplitude of 3 and a right phase shift of [tex]\phi= \frac{\pi}{4}[/tex]  is

[tex]3sin2(x+\phi)[/tex]

The Correct option is D

From the Question we are told that

A graph has

Amplitude of 3

Phase [tex]\phi= \frac{\pi}{4}[/tex]

Generally the equation for the Wave Equation  is mathematically given as

[tex]Asin(kx-wt+\phi)[/tex]

Therefore the Equation for this particular wave is

[tex]3sin2(x+\phi)[/tex]

Hence

The graph of which function has an amplitude of 3 and a right phase shift of [tex]\phi= \frac{\pi}{4}[/tex]  is

[tex]3sin2(x+\phi)[/tex]

The Correct option is D

Answer:

Step-by-step explanation:

The angle marks show that ΔRST is isosceles, so RT = RS. They also show ΔRTU to be equilateral, so UT = RT.

  UT = RS

  x -5 = 15

  x = 20 . . . . . . add 5

__

ΔRTU is equilateral, so ∠RTU is 60°. The angle marked 3y° is complementary to that.

  3y = 30

  y = 10 . . . . . divide by 3
