How do you solve this and what is the answer?

Answer:

A. True

Step-by-step explanation:

Answer: B. False.

Step-by-step explanation:

Hope this helps!

Answer: Option D.

Step-by-step explanation:

When we want to graph a complex number in a coordinate axis, the real part of the complex number is represented by the x-axis, and the complex part is represented by the y-axis.

in this case, we can see that the coordinates of the point are:

(-2, 2)

Then the complex number is:

Z = -2 + 2*i

Now we need to see which one of the given options is equal to this.

Let's check the real part for every option, so we can discard some of them:

A) real part = -2*cos(135°) = 1.41  (we can discard this option)

B) real part = 2*cos(7*pi/4) = 1.41 (we can discard this option)

C) real part = √2*2*cos(225°) = -2

D) real part = √2*2*cos(3*pi/4) = -2  

So options C or D are the correct one, now let's check the complex part for each one

C) complex part = √2*2*sin(225°) = -2    (we can discard this option)

D) complex part =  √2*2*sin(3*pi/4) = 2

So the correct one is the D option.

Answer:

the answer is -1

Step-by-step explanation:

if you multiply the first equation by -1, you get this:

-3x + 4y = 4

and then you can add that to the second equation and eliminate y

2x + 0y = 16

Answer:

Step-by-step explanation:

Answer:

The graph =

Step-by-step explanation:

(a)

distance covered (y) = 174 miles

time taken (x) = 3 hours

Therefore the points = (3, 174) and (0, 0) = stationary position

Find the gradient (m)

m = 174-0 / 3-0

m = 58

Therefore the equation =

(distance = 58 × time)

For the distance = 174 and time = 3 hours, the equation to find either distance or time = y = 58x

(b) the graph is constant, because the time and distance are also contant when the speed used is the same.

Answer:

25pi. 36pi

10pi. 12pi

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

9pi. 49pi

6pi. 14pi

Step-by-step explanation:

Area (A) = πr²

Circumference (C) = 2πr

Blue Circle:

A = (5)²π

A = 25π

C = 2(5)π

C = 10π

Pink Circle:

A = (6)²π

A = 36π

C = 2(6)π

C = 12π

White Circle:

r = 3

A = (3)²π

A = 9π

C = 2(3)π

C = 6π

Red Circle:

A = (7)²π

A = 49π

C = 2(7)π

C = 14π

Step-by-step explanation:

1) Simplify 4² to 16.

[tex] \frac{ - \frac{1}{3} \times - 33 - \frac{1}{2} \times 16 }{ \frac{1}{4} } [/tex]

2) Move the negative sing to the left side.

[tex] \frac{ - ( - \frac{33}{3}) - \frac{1}{2} \times 16 }{ \frac{1}{4} } [/tex]

3) Simplify 33/3 to 11.

[tex] \frac{ - ( - 11) - \frac{1}{2} \times 16 }{ \frac{1}{4} } [/tex]

4) Simplify 1/2 × 16 to 16/2.

[tex] \frac{ - ( - 11) - \frac{16}{2} }{ \frac{1}{4} } [/tex]

5) Simplify 16/2 to 8.

[tex] \frac{ - ( - 11) - 8}{ \frac{1}{4} } [/tex]

6) Remove parentheses.

[tex] \frac{11 - 8}{ \frac{1}{4} } [/tex]

7) Simplify 11 - 3 to 8.

[tex] \frac{3}{ \frac{1}{4} } [/tex]

8) Invert and multiply.

Answer:

a = 42 b = 21

Step-by-step explanation:

a is 42 since it ks vertically opposite 42

To solve for b

360 - (42×2)........to get the angle next to a

=276... Divde answer by 2. Bc there are two of the angles

276÷2 =138

138 + 2b =180

2b = 180 - 138

b = 42 ÷ 2

b = 21

Answer:

x<3

Step-by-step explanation:

5x+2<17

Subtract 2 from both sides.

5x<17−2

Subtract 2 from 17 to get 15.

5x<15

Divide both sides by 5. Since 5 is positive, the inequality direction remains the same.

x=15/5

Divide 15 by 5 to get 3.

x<3

Answer:

2.25

Step-by-step explanation:

2.4 - 0.15

Using place value :

2 = Unit (2 wholes)

4 = tenth place ( 4 tenths)

To subtract 0.15

0 wholes ; 1 tenth ; 5 hundredth

1 tenth can be split into 10 separate hundredths

Hence,

For 2.4

We have ;

2 wholes ; 3 tenths and 10 hundredths

Subtracting 0.15 ;0 wholes ; 1 tenth ; 5 hundredth

(2 - 0) wholes = 2 whole

(3 - 1) tenth = 2 tenth

(10 - 5) hundredth = 5 hundredth

Hence, the difference between (2.4 and 0.15) is :

2 whole ; 2 tenth ; 5 hundredth

Which is equal to : 2.25

Answer: letter d

Step-by-step explanation:

Answer:

Ball D. Among the four balls in this picture, ball D is the only one whose kinetic energy is greater than [tex]0[/tex].

Step-by-step explanation:

Consider an object of mass [tex]m[/tex]. If this object is moving at a speed of [tex]v[/tex], the kinetic energy of this object would be:

[tex]\displaystyle \frac{1}{2}\, m \cdot v^{2}[/tex].

The speed [tex]v[/tex] of ball A, B, and C are all [tex]0[/tex].  Hence, the kinetic energy of these three balls would be [tex]0\![/tex].

The speed of ball D is greater than [tex]0[/tex]: [tex]v = 2\; \rm m \cdot s^{-1}[/tex]. The kinetic energy of this ball would be:

[tex]\begin{aligned} {\rm KE} &= \frac{1}{2}\, m \cdot v^{2} \\ &= \frac{1}{2}\times \rm 0.43\; \rm kg \times \left(2\; \rm m \cdot s^{-1}\right)^{2}\\ &= 0.86\; \rm J\end{aligned}[/tex].

Hence, the kinetic energy of ball D is the greatest among the four balls in this picture.

Answer:

  6/(2+k)

Step-by-step explanation:

The change of base formula is ...

  [tex]\log_a(b)=\dfrac{\log(b)}{\log(a)}[/tex]

Using this, we can take the logarithm base 2 in the change of base formula for the given expression.

  [tex]\log_{20}(64)=\dfrac{\log_2(64)}{\log_2(20)}=\dfrac{\log_2(2^6)}{\log_2(2^2\cdot5)}\\\\=\dfrac{6}{\log_2(2^2)+\log_2(5)}=\boxed{\dfrac{6}{2+k}}[/tex]

__

In addition to the change of base formula, the usual rules of logarithms apply.

  [tex]a^b=m\ \longleftrightarrow \ \log_a(m)=b\\\log(ab)=\log(a)+\log(b)[/tex]
