Answer:

(-3,0) ; (1,0)

Step-by-step explanation:

We have to solve the associated equation:

-2x^2 -4x + 6 = 0

-x^2 - 2x + 3 = 0

x^2 + 2x -3 = 0

Δ/4 = 1 + 3 = 4

x1 = -1 + 2 = 1

x2 = -1 -2 = -3

Answer:

650 ft^2

Step-by-step explanation:

Without the gap, the area of the rectangle is 20ft x 35ft = 750 ft^2. The gap is a square having 10ft on the side so its area is 10ft x 10ft = 100 ft^2. Subtracting the area of the square gap from the rectangle gives you 650 ft^2.

Step-by-step explanation:

When a transversal line crosses parallel lines, it creates 8 angles. If the transversal crosses at right angles, every one of those angles is a right angle.

If the transversal does not cross at right angles, it creates 4 acute angles and 4 obtuse angles. The acute and obtuse angles are supplementary to each other, since they form linear pairs.

All of the acute angles are congruent, as are all of the obtuse angles. [this is the simplicity of it — only true if the lines are parallel]

__

Different pairs of angles have names. Angles on opposite sides of a point of intersection are "vertical" angles. Angles between the parallel lines are "interior" angles, and those outside are "exterior" angles. Angles on the same side of the transversal are called "same-side" or "consecutive" angles. Angles on opposite sides of the transversal are called "alternate" angles.

Angles in the same direction from the points of intersection (upper-left, for example) are called "corresponding" angles.

__

Angle relationships are often described in the terms described above. For example, every pair of "corresponding angles" is congruent, as are "alternate interior" or "alternate exterior" angles. In any geometry (not just one like this), "vertical angles" are congruent.

_____

You are given the measure of angle 4 (122°). This tells you every obtuse angle in the figure is 122°, and every acute angle in the figure is 180°-122° = 58°. All you need to do to find the angle measures is identify the angle as acute or obtuse.

For justification, you may be expected to determine the relationship of the requested angle to angle 4.

7. ∠8 — part of linear pair; supplementary to ∠4

8. ∠5 — alternate exterior; congruent to ∠4

9. ∠2 — corresponding; congruent to ∠4

10. ∠1 — consecutive exterior; supplementary to ∠4

11. ∠6 — vertical to ∠1*, so the same measure as ∠1

12. ∠7 — vertical to ∠4; congruent to ∠4

__

* angles 1 and 4 have no named relationship. angle 2 is corresponding to angle 4, and angle 5 is alternate exterior with respect to angle 4. Each of those is supplementary to angle 6, so angle 6 is supplementary to angle 4.

Answer:

11.6km/hr

The scientific notation of 78,400,000 will be 7.84 × 10⁷.

Index (indices) in Maths is the power or exponent which is raised to a number or a variable.

For example 5³ = 5²5 here we break 5³ into 5² and 5 so it is called the law of indices.

An algebraic expression is a quantity made up of symbols and processes + - / and multiplication Expressions utilizing indices are made simpler using the laws of indices.

Scientific notation of any number is given in form of a.bcde...× 10^something

Given the number,

78,400,000

Multiply and divide by 10⁷

⇒ 78,400,000 × 10⁷/10⁷

⇒ 7.84 × 10⁷.

Hence "The scientific notation of 78,400,000 will be 7.84 × 10⁷".

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos R = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{RS}{QR}[/tex] = [tex]\frac{61}{78}[/tex] , then

∠ R = [tex]cos^{-1}[/tex] ([tex]\frac{61}{78}[/tex] ) ≈ 39° ( to the nearest degree )

The surface area of a rectangular prism is 872 square inches.

The surface area of a cuboid is the total area of all six faces of the three-dimensional shape. Each face of the cuboid is a rectangle, and the surface area of the cuboid is the sum of the areas of all six of these faces. In other words, the surface area is the amount of space that the cuboid occupies in total.

1) Given that, length=17 inches, breadth=8 inches and height=12 inches.

Here, surface area = 2(lb+bh+hl)

= 2(17×8+8×12+12×17)

= 2×436

= 872 square inches

2) Given that, diameter=14 mm and height=29 mm

We know that, surface area of cylinder = 2πr(r+h)

= 2×3.14×14(14+29)

= 2×3.14×14×43

= 3780.56 square mm

3) Here, total surface area = 8×3+6×3+11×3+2(1/2×11×4.3)

= 24+18+33+47.3

= 122.3 square cm

4) Total surface area = 2(14×8)+19×8+2(1/2×(19+5)×12.1)

= 224+152+290.4

= 666.4 square feet

Therefore, the surface area of a rectangular prism is 872 square inches.

Answer: 459 cheeseburgers

Step-by-step explanation:

To find out the number of cheeseburgers that can be made, divide the amount of meat set aside by the amount of meat it takes to make one cheeseburger.

The amount of meat they have is:

= 114²/₃

= 344/3

Number of cheeseburgers is:

= 344/3 ÷ 1/4

= 344/3 * 4/1

= 1,376 / 3

= 458.67

= 459 cheeseburgers

Answer:

b = 60

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

b² + 63² = 87²

b² + 3969 = 7569 ( subtract 3969 from both sides )

b² = 3600 ( take the square root of both sides )

b = [tex]\sqrt{3600}[/tex] = 60
