Consider the following equation.
y = - 15
Which of the following lines is perpendicular to the one above?
OA
y = - - 20
ОВ.
y =
21 – 15
OC.
y = - + 19
OD
y = 1 + 14

£40 and £20

Step-by-step explanation:

let the parts be 2x and x (2:1)

2x+x=£60

or, 3x= £60

or, x= £20

2x=2×£20=£40

x=£20

Answer:

θ = -60.94°

Step-by-step explanation:

The given vector is:

v = -5i+9j

We need to find the angle of this vector.

The angle of this vector form is given by :

[tex]\tan\theta=\dfrac{y}{x}\\\\\tan\theta=\dfrac{9}{-5}\\\\\tan\theta=-1.8\\\\\theta=\tan^{-1}(-1.8)\\\\=-60.94^{\circ}[/tex]

So, the angle of this vector is -60.94°.

Answer:

Step-by-step explanation:

[8 * (7÷7)]² = [8 * 1]²

                 = 8²

                 = 64

The operation in the inside parenthesis should be done first.

Answer:

145.8cm squared

Step by step:

16.2 divided by 3 = 5.4cm

In the second line where 2 bricks are horizontal and 2 are vertical:

2x + 3y = 16.2

3y = 16.2 - 2 x 5.4

y = 1/3 x 5.4

y = 1.8cm

Hence, height and length of each triangle is 1.8cm and 5.4cm

Complete length = 16.2 cm

Complete height = 2y + x = 2 x 1.8 + 3.4

                            = 9 cm

Area overall = 16.2 x 9 = 145.8cm squared

Step-by-step explanation:

x equals 40

Answer:

  779.4 square units

Step-by-step explanation:

You seem to have several problems of this type, so we'll derive a formula for the area of an n-gon of radius r.

One central triangle will have a central angle of α = 360°/n. For example, a hexagon has a central angle of α = 360°/6 = 60°. The area of that central triangle is given by the formula ...

  A = (1/2)r²sin(α)

Since there are n such triangles, the area of the n-gon is ...

  A = (n/2)r²sin(360°/n)

__

For a hexagon (n=6) with radius 10√3, the area is ...

  A = (6/2)(10√3)²sin(360°/6) = 450√3 ≈ 779.4 . . . . square units

Answer: Segment (of a Circle) A segment is a region bounded by a chord of a circle and the intercepted arc of the circle. A segment with an intercepted arc less than a semicircle is called a minor segment. A sector with an intercepted arc greater than a semi-circle is called a major segment.

I hope this helped you but, I didnt know the ones on your assignment :)

Answer: 1

Step-by-step explanation:

Answer:

1/4 because

1st term 64 : 64/4 = 16

2nd term 16 : 16/4 = 4

3rd term 4 : 4/4 = 1

4th term 1 : 1/4 = 1/4

5th term 1/4

Answer:

[tex]\text{D. The terms may be combined.}[/tex]

Step-by-step explanation:

Recall that [tex]\sqrt{a\cdot b}=\sqrt{a}\cdot\sqrt{b}[/tex]. Using this, we can simplify and combine the two terms:

[tex]6\sqrt{32}-12\sqrt{72},\\=6\cdot \sqrt{4}\cdot \sqrt{8}-12\cdot \sqrt{9}\cdot \sqrt{8},\\=6\cdot 2\cdot \sqrt{8}-12\cdot 3\cdot \sqrt{8},\\=12\sqrt{8}-36\sqrt{8},\\=-24\sqrt{8}=-24\cdot\sqrt{4}\cdot\sqrt{2}=\boxed{-48\sqrt{2}}[/tex]. Therefore, the terms may be combined.

Answer:

Which language is this I don't understand

Answer:

Step-by-step explanation:

Explicit formula of a G.P. is given by,

[tex]a_n=a(r)^{n-1}[/tex]

Here, [tex]a_n[/tex] = nth term

a = First term

n = number of term

r = common ratio

Given sequence is 3, 6, 12, .......

a = 3

r = [tex]\frac{6}{3}[/tex] = 2

Therefore, explicit formula will be,

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

Option (3) is the answer.

Parent function → f(x) = 3ˣ

Transformed function → g(x) = [tex]3^{x+5}[/tex]

Since, g(x) = f(x + 5)

Therefore, function 'f' has been shifted 5 units left.

Option (1) is the answer.

The the total cost of the item of interest is ...

  (1.09)($84) = $91.56

Answer:

Father's age = 48

Daughter's age = 24

Step-by-step explanation:

Let x be father's age and y be daughter's age.

1st equation:

x = 2y

2nd equation:

(x - 16) = 4(y - 16)

Replacing value of x from 1st equation,

(2y - 16) = 4(y - 16)

2y - 16 = 4y - 64

4y - 2y = 64 - 16

2y = 48

y = 48/2

y = 24

And,

x = 2y

x = 2 x 24

x = 48

8x - x = 64 - 16

7x = 48

Answer:

29.3

Step-by-step explanation:

to find average you find the sum of all the minutes she practiced and divide it by the total amount of day she practiced.

first we have to find the sum of the minutes she practiced:

20+30+40+38+25+22+39+22+26+31

this equation is equal to 293 minutes she practiced in total. Now we have to divide this by the total amount of days she practiced whice according to the data is 10! So:

293/10 =29.3

Step-by-step explanation:
