Given the vertices:

C(-2, 4), D(1, 5), and E(1, 2)

Let's identify the reflection of the figure across the x-axis.

After a reflection across the x-axis, we have the rule:

(x, y) ==> (x, -y)

Thus, we have:

C(-2, 4) ==> C'(-2, -4)

D(1, 5) ==> D'(1, -5)

E(1, 2) ==> E'(1, -2)

Therefore, after a reflection over the x-axis, we have:

C'(-2, -4), D'(1, -5), E'(1, -2)

ANSWER:

C'(-2, -4), D'(1, -5), E'(1, -2)

The area of a circle with chord length of 3√2cm is 28. 3 cm²

<h3>How to determine the area</h3>

The formula chord length of  a circle is expressed as;

Chord Length = 2 × r × sin(c/2)

Where;

  • r is the radius
  • c is the angle formed by the chord and the circumference of the circle
  • Chord length = 3√2

Let's substitute into the formula

3√2 = 2r sin 90/ 2

3√2 = 2r sin 45

3√2 = 2r × 1/ √2

2r = 3√2 ×√2/ 1

2r = 6

Make 'r' the subject

r = 6/2

r = 3cm

The formula for area of a circle is expressed as;

Area = πr²

Area = 3.142 × (3)²

Area = 3. 142 × 9

Area = 28. 3 cm²

Thus, the area of a circle with chord length of 3√2cm is 28. 3 cm²

Which equation can be rewritten as x + 4 = x2? Assume x greater-than 0 StartRoot x EndRoot + 2 = x StartRoot x + 2 EndRoot = x S
Mila [183]

We have been given an equation x+4=x^2. We are also told that x is greater than 0. We are asked to choose the equation that can be written as our given equation.

Since x is greater than, so we will take positive root on both sides of our given equation as:

\sqrt{x+4}=\sqrt{x^2}

\sqrt{x+4}=x

Upon looking at our given choices, we can see that option C is same as our answer.

Therefore, option C is the correct choice.

Find the surface area of the prism formed by the net
Lunna [17]
ANSWER

T.S.A=1960m^2

EXPLANATION

The diagram represents the net of a rectangular prism.

The dimensions are,

l=42m

w = 14m

and

h = 7m

The total surface area of a rectangular prism is given by:

T.S.A=2(lw + lh + wh)

We substitute the values to obtain,

T.S.A=2(42 \times 14 + 42 \times 7 + 14 \times 7)

T.S.A=2(980)m^2


T.S.A=1960m^2
