1+1= 2

Step-by-step explanation:

Area of a rectangle equals Length ×Breadth The rectangle's size in red is equal to 0.5833 square units .

The size of a rectangle. A = l × b. Once the length and breadth are known for any rectangle, the area may be determined. The area of the rectangle is calculated as a square-unit dimension by multiplying length and width.

length (a) = 7/8

Width (b) = 2/3

Area (A) = 0.5833 square units

P = 3.0833 for the perimeter.

Parallel (d) equals 1.1

A shape's surface area is measured by its area. By multiplying the length and breadth of a rectangle or square, you can get its area. Area A is equal to x times y. Side x Side equals the area of a square. So, Side2 square units = the area of the square. therefore a square's perimeter is equal to four units of its sides.

Answer:

The answer is f(x)=(x+3)2−4 .

Step-by-step explanation:

To convert to vertex form, you must complete the square. We add k to complete the square inside the brackets, but whatever we add inside, we must subtract outside the brackets to keep the equation balanced.

Therefore , the solution of the given problem of angles comes out to be

x =  42.5° and  y = 20°.

In Euclidean geometry, an arc is a construct made up of two rays that split at the apex and vertex, which are located in the middle of the angle. The sides or loops are the name given to these rays. A combination of two rays may result in an inclination that is inside the surfaces in which they are located. Two planes can be combined to form an angle as well. They are referred to as dihedral angles. Two line rays with end points can be arranged in a variety of ways to create styles in two dimensions.

Here,

Given :

=> 4y + 5y = 180°

=> 9y = 180°

=> y = 180°/9

=> y = 20°

and

=> 2x + 5 + 90° = 180°

=> 2x + 95° = 180°

=> 2x = 85°

=> x =  42.5°

Therefore , the solution of the given problem of angles comes out to be

x =  42.5° and  y = 20°.

The train which is travelled same distance with two different speeds, the slower speed of a train is 25.075 km/hr

The distance covered by the object is equal to the product of the speed at which the object is moving and time taken for covering the distance.

Distance = Time × Speed

Given that,

A train does a journey without stopping in 8 hours

it had traveled 5 km/hr faster , Time taken = 6 hours 40 min = 6.67hr

slower speed = ?

Suppose total distance covered =  X

⇒  X = V × 8    _____(i)

If he travelled 5 km/hr faster

⇒  X = (V+5) × 6.67  _____(ii)

For i and ii distance is same so we can equate both the values,

⇒ V × 8  = (V+5) × 6.67

⇒ 8V = 6.67V + 33.35

⇒ 1.33V = 33.35

⇒ V = 25.075

Hence, the slower speed is 25.075 km/hr

The compound experiment is the probability of heads on a coin and 4 on a number cube which is P = ( 1/12 )

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability be represented as P

Now , the equation will be

a)

The probability of rolling a 6 on a number cube

The value of P = 1/6

b)

Answer:

Step-by-step explanation:

The parabola equation is x = (-1/2)y2 - 4y - 1.5 when the focus and directrix are (1, 4) and 5 respectively.

An equation is a mathematical formula that joins two statements and uses the equal symbol (=) to indicate equivalence. A mathematical statement that proves the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign divides the variables 3x + 5 and 14. The relationship between the two sentences on either side of a letter is explained by a mathematical formula. There is frequently only one variable, which also serves as the symbol. for instance, 2x - 4 = 2.

given

The equation's fundamental form is:

4p(x-h) = (y-k) (y-k)

The vertex is at 2 (h,k).

P is the separation between the vertex and the directrix or focus. Between the two is where the vertex is located.

Directrix: x=2, focus: (1, -4).

Vertex at the perpendicular midpoint of (1.5, -4)

Parabola opens left because it faces the focus and moves away from the directrix. This implies that p will be negative. P would be positive if the parabola opened to the right. p = -0.5

Putting this together:

4(-0.5)(x-1.5) = (y-(-4))2

-2(x-1.5) = (y+4)2

-2(x-1.5) = y2 + 8y + 16

x - 1.5 = (-1/2)(y2 + 8y + 16)

x = (-1/2)y2 - 4y - 8 + 1.5

The parabola equation is x = (-1/2)y2 - 4y - 1.5 when the focus and directrix are (1, 4) and 5 respectively.

+26

2.73

Answer:

To multiply 1.3 by 2.1, we need to use the distributive property of multiplication, which states that:

a × (b + c) = a × b + a × c

Using this property, we can break down 2.1 as the sum of 2 and 0.1:

1.3 × 2.1 = 1.3 × (2 + 0.1)

= 1.3 × 2 + 1.3 × 0.1

= 2.6 + 0.13

= 2.73

Therefore, 1.3 multiplied by 2.1 equals 2.73.

Suppose we have a quadratic equation, in the following format:

The roots are p and q.

As, The Theorem states that:

p + q= -b/a

pq= c/a

We have given the polynomial  x²-17x+c=0

So, a= 1, b= -17

Since the difference of the solutions is 1, we have that:

p -q= 1

p = 1+ q

Now, using p + q= -b/a

1 + q + q= -(-17)/1

2q +1 = 17

2q= 16

q= 16/2

q= 8

Because all sides are congruent, it is an equilateral triangle. You can see this based on the lines on the sides of the triangle. Because of this, all angles are equal to each other. In a triangle, the sum of angles is 180 degrees with each angle being equal to 60 degrees.  

Because both angles are equal, you get. Since you're solving for x, set 5y equal to 60 then solve for x.

5y = 2x - 4

60 = 2x - 4

60 +4 = 2x

64 = 2x
