2499 is your answer

Answer:

2499

Step-by-step explanation:

Here's one mental approach:

51*49

(50+1)(50-1)

(a+b)(a-b)=a²-b²

(50+1)(50-1)=50²-1²

2500-1

2499

Or you could say (51*50)-51 = 2550-51 = 2499

Answer:

[tex]\frac{1}{x^2}[/tex]

Step-by-step explanation:

[tex]x^{-2}[/tex]

[tex]=\frac{1}{x*x}[/tex]

[tex]=\frac{1}{x^2}[/tex]

Therefore, [tex]\frac{1}{x^2}[/tex] is the answer to this question.

Answer:

A Reflection: (-1, 3) (reflected from y-axis or "vertical line")

B Reflection: (2, -2) (reflected from y-axis or "vertical line")

C Reflection: (4, 5) (reflected from y-axis or "vertical line")

D Reflection: (-2, -5) (reflected from y-axis or "vertical line")

Answer:

 320 cu. yd.      

Step-by-step explanation:

V = Bh   where B is the area of the base (triangle) and h is the height of prism

B = bh/2 = 8(8)/2 = 64/2 = 32

height of prism = 10

V = 32(10) = 320 cu. yd.

Answer:

Son = 15 and father = 40

Step-by-step explanation:

Let, the age of son be x and father be y.

According to the question,

2x + y = 70

or. y = 70 - 2x ..................................(1)

Also,

2y + x = 95

or, 2(70 - 2x) + x = 95 (From 1)

or, 140 - 4x + x = 95

or, 45 = 3x

∴ x = 15

Now,

Substituting value of x in (1)

y = 70 - 30 = 40

∴ The present ages of son and father are 15yrs and 40yrs respectively.

Given:

Consider the dimensions of a rectangular prism are 4 in by 3 in by 10 in.

To find:

The length of the diagonal.

Solution:

Length of diagonal of a rectangular prism is:

[tex]d=\sqrt{l^2+b^2+h^2}[/tex]

Where l is length, b is breadth and h is height.

The dimensions of a rectangular prism are 4 in by 3 in by 10 in. So, the length of diagonal of the rectangular prism is:

[tex]d=\sqrt{(4)^2+(3)^2+(10)^2}[/tex]

[tex]d=\sqrt{16+9+100}[/tex]

[tex]d=\sqrt{125}[/tex]

[tex]d=5\sqrt{5}[/tex]

Approximate the value to the nearest tenth.

[tex]d\approx 11.2[/tex]

Therefore, the length of diagonal of the rectangular prism is 11.2 in.

Answer:

5 c = 45 , d = 97

Step-by-step explanation:

5) You know the entire triangle has a total of 180 degrees, you also know that angle c + 135 has to equal 180.

So for angle C, you will set up your formula c=180-135 = 45

Now you set up your formula for angle d.

180=angle c + angle d +38

180 = 45 + D + 38 -> D = 180-45-38 = 97

Follow the same steps for 6 and 7

Answer:

D

Step-by-step explanation:

1. Make it into a y = x equation

       y = 9x +7

2. change x to y and y to x

       x = 9y + 7

3. Isolate y ( if not possible, use implicit differentiation but here you can)

      x-7 = 9y

      1/9x-7/9 = y

Answer:

[tex]x=15[/tex]

Step-by-step explanation:

The two marked angles form one side of a line, which we know to be [tex]180^{\circ}[/tex]. Therefore, the angles are supplementary and we can set up the following equation:

[tex]133+(3x+2)=180,\\3x+2=47,\\3x=45,\\x=\boxed{15}[/tex]

Answer:

To find the amount after the discount you have to multiply 7.5 by 0.75, Using a calculator would be faster but you can also do it by hand. The answer is 5.625

Step-by-step explanation:

To find the answer you need to do multiplication.

Use this form to do it more easily.

  7.5

*  0.75      

   0.375

+ 5.25

then you add

Answer:

[tex]d(P,Q) = \sqrt{34}[/tex]

The midpoint of the segment is M(27.5, -13.5).

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Distance between P(25,-15) and Q​(30,-12)

[tex]d(P,Q) = \sqrt{(30-25)^2+(-12-(-15))^2} = \sqrt{34}[/tex]

So

[tex]d(P,Q) = \sqrt{34}[/tex]

Coordinates of the midpoint M of the segment PQ.

Mean of the coordinates of P and Q. So

[tex]x_M = \frac{25+30}{2} = \frac{55}{2} = 27.5[/tex]

[tex]y_M = \frac{-15-12}{2} = -\frac{27}{2} = -13.5[/tex]

The midpoint of the segment is M(27.5, -13.5).

Answer:

AB = 3π units

Step-by-step explanation:

The arc length is calculated as

AB = circumference of circle × fraction of circle

     = 2πr × [tex]\frac{45}{360}[/tex]

     = 2π × 12 × [tex]\frac{1}{8}[/tex]

     = 24π × [tex]\frac{1}{8}[/tex]

     = 3π units

Answer:

The correct option is - D.

Step-by-step explanation:

To find - Select the correct answer. The parent tangent function is transformed such that its period is halved. Which graph could represent the transformed function?

Solution -

We know that,

The parent tangent function is -

f(x) = tan(x)

Period of Parent function = [tex]\pi[/tex]

Now,

If Period is half,

Then

The function is transformed to

f(x) = tan(2x)

So,

The graph becomes

The correct option is - D.
