Answer:

The coordinates are B'(1,0.5)

Step-by-step explanation:

Since the center of dilation is at the origin, we just divide the coordinates of the point by the scale factor.

In this question:

Scale factor of 2

B(2,1)

2/2 = 1

1/2 = 0.5

So, the coordinates are B'(1,0.5)

Answer:

c+d = 5/3

Step-by-step explanation:

3(c+d) = 5

Divide each side by 3

3/3(c+d) = 5/3

c+d = 5/3

Answer:

3(1+d)=5

3×1=3

3×d=3d

:3+3d-5

3d-2

3d=2 (Devide both sides by 3)

d=2/3

Answer:

Step-by-step explanation:

Although you can start with 4x^2-2x-4=0, it's just slightly easier to reduce the coefficients.  4x^2-2x-4=0 becomes 2x^2 - x - 2 = 0.

The discriminant (part of the quadratic formula) is b^2 - 4ac.  Using b = -1. a = 1 and c = -2, we get (-1)^2 - 4(2)(-2), or 17.

                                                       -b ± √(b^2 - 4ac)

Then the quadratic formula   x = ---------------------------

                                                                 2a

                                         -(-1) ± √17           1 ± √17

takes on the values  x = -----------------  =  ---------------

Answer:

36°

Step-by-step explanation:

let x be the required angle then

x = [tex]\frac{2}{3}[/tex] ( 90 - x)  [ complementary angles sum to 90° ]

x = 60 - [tex]\frac{2}{3}[/tex] x ( add [tex]\frac{2}{3}[/tex] x to both sides )

[tex]\frac{5}{3}[/tex] x = 60 ( multiply both sides by [tex]\frac{3}{5}[/tex] )

x = 36°

note 36° is [tex]\frac{2}{3}[/tex] of 54°

Answer:

6:5

Step-by-step explanation:

Divide both sides by y . ⇒5xy=6y y. ⇒5xy=6. Divide both sides by 5 . ⇒5 x5 y=65. ⇒xy=65. ⇒x:y=6:5.

The ratio between x and y, when 5x = 6y, is 6:5.

Given is an equation 5x = 6y, we need to find the ratio between x and y,

To determine the ratio of x to y in the equation 5x = 6y, we need to isolate one of the variables and express it in terms of the other.

Let's isolate x:

5x = 6y

Divide both sides of the equation by 5:

x = (6y) / 5

Now we have an expression for x in terms of y. The ratio of x to y can be represented as:

x/y = (6y) / (5y)

The y terms cancel out:

x/y = 6/5

Therefore, the ratio of x to y is 6:5.

Answer:

[tex]H_a > \mu = 24.5[/tex]

Step-by-step explanation:

Given

[tex]n = 28[/tex] --- sample size

[tex]\bar x = 25.3[/tex] --- Mean

[tex]x = 24.5[/tex] --- Average

Required

Determine the alternate hypothesis

From the question, we understand that it is safe to drink water at 24.5 ppb or less.

This implies that the null hypothesis is:

[tex]H_0 \le \mu = \bar x[/tex]

i.e.

[tex]H_0 \le \mu = 24.5[/tex]

The opposite of [tex]\le[/tex] is [tex]>[/tex]

So, the alternate hypothesis will be:

[tex]H_a > \mu = \bar x[/tex]

[tex]H_a > \mu = 24.5[/tex]

Hence: (c) is correct

Step-by-step explanation:

v=pi*r^2h

Answer:

5626.9m³

Step-by-step explanation:

V = πr²h

radius = 8

height = 28

to make it easier first step is to get the multiply the radius and the height but first multiple the radius by itself

=> 8 x 8 = 64

=> 64 x 28 = 1792

then multiply 1792 by π (3.14)

=> 1792 x 3.14 = 5626.88

when you round the answer it will be 5626.9
