Answer: 500 as 49 is closer to 500 by 1, if it was 550 then it would have been 600. It's basically just estimation or rounding it off to the nearest hundred

Answer: the slope is 4 and the y intercept is 3. Hope this helps!

Answer:

slope = 4

y-intercept = 3

Step-by-step explanation:

Note the slope-intercept form: y = mx + b

x & y is found inside the point (x , y).

m is the variable for the slope.

b is the variable for the y-intercept.

Find the corresponding number for the corresponding variable.

slope = m = 4

y-intercept = b = 3

Answer:

-3/7

Step-by-step explanation:

If the lines are parallel, they have the same slope.

The green line has a slope of -3/7, so the red line must have a slope of -3/7

Answer:

First option.

Step-by-step explanation:

In this case you need to remember that an angle formed by two intersecting chords is equal to the sum of the intercepted arcs divided by 2. This is:

[tex]Angle\ formed\ by\ two\ intersecting\ chords=\frac{1}{2}(Sum\ of\ intercepted\ arcs)[/tex]

You can identify in the figure that the angle ∠1 is an angle formed by two intersecting chords. Therefore, since the intercepted arcs are SP and QR, you can say the following:

[tex]m\angle 1=\frac{1}2}(mSP+mQR)[/tex]

You can observe that this matches with the first option.

Answer:

Step-by-step explanation:

Answer:

(x + 3)² = 15

Step-by-step explanation:

Given

x² + 6x - 6 = 0 ( add 6 to both sides )

x² + 6x = 6

To complete the square

add (half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = 6 + 9

(x + 3)² = 15

Follow below steps:

The question asks about rewriting the quadratic equation x^2+6x-6=0 by completing the square. To complete the square for an equation of the form ax^2+bx+c=0, we need to add and subtract the square of half the coefficient of x, which is (b/2)^2, to make it a perfect square trinomial.

Here are the steps for completing the square for the given equation:

Divide all terms by the coefficient of x^2 if it is not 1 (in this case, it is already 1).

Move the constant term to the other side of the equation: x^2 + 6x = 6.

Find (b/2)^2, where b is the coefficient of x, which is 6 in this case. So, (6/2)^2 = 9.

Add and subtract this value inside the equation: x^2 + 6x + 9 - 9 = 6.

Write the left-hand side as a perfect square and simplify the right-hand side: (x+3)^2 - 9 = 6.Finish by repositioning: (x+3)^2 = 15.

The equation x^2+6x-6=0 rewritten by completing the square is (x+3)^2 = 15.

Choice B), [tex]f(x) = -3|x|[/tex].

Each point on the graph of [tex]g(x)[/tex] can be represented as [tex](x, g(x))[/tex].

When the graph of [tex]g(x)[/tex] is reflected over the x-axis, each point on the graph is also reflected over the x-axis. The x-coordinate of each point will not change but the sign in front of the y-coordinate will flip. For example, [tex]1[/tex] (same as [tex]+1[/tex]) will become [tex]-1[/tex], and vice versa.

Answer:

C

Step-by-step explanation:

x² + 6x = 18

To complete the square, take the coefficient of the x term, halve it, square the result, then add to both sides.

(6/2)² = 3² = 9

x² + 6x + 9 = 18 + 9

(x + 3)² = 27

x + 3 = ±√27

x = -3 ± √27

x^2 + 2 = 38

Subtract 2 from each side:

x^2 = 36

Take the square root of both sides:

x = √36

Answer:

1000 times

Step-by-step explanation:

The Richter scale is a logarithmic scale, so we can say an earthquake of magnitude 8 on the Richter scale shows an intensity of 10^8.

In the same way, an earthquake of magnitude 5 on Richter scale will have an intensity of 10^5.

To evaluate the difference, we divide one by the other.

10^8 / 10^5 = 10^3 = 1,000

An earthquake of intensity of 8 is 1,000 times more powerful than one of intensity 5.

Answer:

on edge

A magnitude 8 earthquake is 1,000 times more intense than a magnitude 5 earthquake. A magnitude 8 earthquake is 108 times more intense than a standard earthquake, while a magnitude 5 earthquake is 105 times more intense than a standard earthquake, and 108 ÷ 105 = 103. Each unit increase on the Richter scale corresponds to an intensity increase by a factor of 10. So from 5 to 8 on the Richter scale, the intensity increases by 103 = 1,000.

Answer:

(-2, 6) on edge

Step-by-step explanation:

Answer:

=204.13 inches.

Step-by-step explanation:

Using the side x, we can use sine to find the hypotenuse of the triangle with the angle marked 30°.

Sin 30 =x/hypotenuse.

sin 30 = 27/hyp

hyp= 27/sin 30

=54 inches

We can also find the adjacent as follows.

Cos 30 = adjacent/ 54

Adjacent= 54 cos 30

=46.77 inches

Using the angles marked 45 we can find the hypotenuse of the isosceles triangle.

sin 45= x/hypotenuse

sin 45 =27/hypotenuse

hypotenuse = 27/sin 45

=38.18 inches

The hypotenuse of both the triangles making the isosceles triangle are 38.18 inches long.

Perimeter = 54+ 46.77+27+ 38.18+38.18

=204.13 inches.

The total perimeter of the given figure is 204.13 inches

Let's break down the solution step by step:

1. Triangle with 30° Angle:

  - We have a right triangle with one angle measuring 30°.

  - The side opposite the 30° angle (labelled as "x") is 27 inches.

  - We want to find the hypotenuse (the longest side).

  - Using the sine function:

   [tex]\[ \sin(30°) = \frac{x}{\text{hypotenuse}} \] - Solving for the hypotenuse: \[ \text{hypotenuse} = \frac{27}{\sin(30°)} = 54 \text{ inches} \][/tex]

2. Adjacent Side of the 30° Triangle:

  - We can also find the adjacent side (labelled as "adjacent") using the cosine function:

   [tex]\[ \cos(30°) = \frac{\text{adjacent}}{54} \] - Solving for the adjacent: \[ \text{adjacent} = 54 \cos(30°) = 46.77 \text{ inches} \][/tex]

3. Isosceles Triangle with 45° Angles:

  - We have an isosceles triangle with two angles measuring 45° each.

  - The side opposite each 45° angle is also 27 inches (since it's an isosceles triangle).

  - We want to find the hypotenuse of this triangle.

  - Again using the sine function:

  [tex]\[ \sin(45°) = \frac{x}{\text{hypotenuse}} \] - Solving for the hypotenuse: \[ \text{hypotenuse} = \frac{27}{\sin(45°)} = 38.18 \text{ inches} \][/tex]

4. Total Perimeter:

  - The perimeter of the entire figure is the sum of all sides:

   [tex]\[ \text{Perimeter} = 54 + 46.77 + 27 + 38.18 + 38.18 = 204.13 \text{ inches} \][/tex]

Therefore, the total perimeter of the given figure is 204.13 inches.

To find sin 75°, use the half-angle identity for sine: sin(2θ) = 2sinθcosθ. Since sin 150° = 1/2, find cos 150° using the Pythagorean identity. Then, use the half-angle identity for sine to find sin 75°.

To find sin 75°, we can use the half-angle identity for sine: sin(2θ) = 2sinθcosθ.

Given that sin 150° = 1/2, we can find cos 150° using the Pythagorean identity: sin²θ + cos²θ = 1.

sin²150° + cos²150° = 1, (1/2)² + cos²150° = 1, cos²150° = 1 - (1/4), cos²150° = 3/4.

Since 150° falls in the second quadrant, it has a negative value: cos 150° = -√(3/4) = -√3/2.

Now, we can use the half-angle identity for sine: sin 75° = 2sin(150°/2)cos(150°/2).

sin 75° = 2(sin 150°/2)(cos 150°/2) = 2(√(1/4))(√3/2) = √3/2.

Final answer:

To find sin 75°, we can use the double angle formula for sine and substitute the given value of sin 150°. The result is sin 75° = cos 75°.

Explanation:

To find sin 75°, we can use the double angle formula for sine.

The formula is sin 2θ = 2sin θcos θ. We know that sin 150° = 1/2, so we can substitute θ = 75° into the formula:

sin 2(75°) = 2sin 75°cos 75°

Using the double angle formula, we get:

2sin 75°cos 75° = 2(1/2)cos 75° = cos 75°

Therefore, sin 75° = cos 75°
