Answer:

The letter 'E' has exactly one line of symmetry passing from it's center.

Step-by-step explanation:

We are given the letter 'E' for checking whether it have symmetry.

For that, first of all let us understand what does line of symmetry means;

A line of symmetry is a line that separates an object into two identical sections that are mirror images of one another.

Now,

The letter 'E' has exactly one line of symmetry passing from it's center.

Furthermore, just like the letter 'E' various other letters also have exactly one line of symmetry.

For example, Letter A, B, C, D, E, K, M, have exactly 1 line of symmetry.

Answer: Formula used for pyramid is (V= 1/3 Bh   SA: 1/2 P*l+B) Final answer is SA=110.4   V=64

Step-by-step explanation:

P= Perimeter

l= length

B= Base

To find the perimeter you add all the sides of the base. (4+4+4+4)=16

To find the length you can use Pythagorean Theorem which is a(squared) + b(squared) = c(squared) where c is the hypotenuse. [tex]2^{2}[/tex] + [tex]12^{2}[/tex]= [tex]x^{2}[/tex]

4+144=[tex]x^{2}[/tex]

164=[tex]x^{2}[/tex]

[tex]\sqrt{164}[/tex]=x

x=12.8

To find the base it will be l*w (4*4)=16

Then you plug it in the formula for SA which will be

SA=1/2 16*12.8+16

SA=110.4

For Volume, it will be

V=1/3 Bh

V= 1/3 16(12)

V= 64

Answer:

x = 5

Step-by-step explanation:

Solve for x:

-1 - 5 (-x - 1) + 4 x = 49

-5 (-x - 1) = 5 x + 5:

(5 x + 5) + 4 x - 1 = 49

Grouping like terms, 5 x + 4 x - 1 + 5 = (5 x + 4 x) + (-1 + 5):

((5 x + 4 x) + (-1 + 5)) = 49

5 x + 4 x = 9 x:

9 x + (-1 + 5) = 49

5 - 1 = 4:

9 x + 4 = 49

Subtract 4 from both sides:

9 x + (4 - 4) = 49 - 4

4 - 4 = 0:

9 x = 49 - 4

49 - 4 = 45:

9 x = 45

Divide both sides of 9 x = 45 by 9:

(9 x)/9 = 45/9

9/9 = 1:

x = 45/9

The gcd of 45 and 9 is 9, so 45/9 = (9×5)/(9×1) = 9/9×5 = 5:

Answer: -8.5 or -17/2

Step-by-step explanation: you have to put the info into an equation. product of a number x and 7 is 7x. two less than mean subtracting two and 5 times the difference of x and 3 translates to 5(x-3). Once put into an equation, it'll look like 7x = 5(x-3) - 2. Now solve this equation for x and you'll end up with -8.5 in decimals or -17/2 in fractions.

Answer:

First, we need to find the slope.

Rise/Run

440-410/6-4

30/2 = 15

m = 15

Now we need to find the y-intercept using the slope.

15(4) = 60

410 - 60 = y int

b = 350

y=mx + b

The dot product of two vectors gives scalar quantity and between scalar quantity, we can not apply any product so options (b), (d), and (e) are not meaningful.

An item with both magnitude and direction is referred to be a vector.

A vector can be visualized geometrically as a straight spline, with a pointing in the orientation and a length equal to the value of the vector.

A line with an arrow in its direction can also be used to represent a vector, and the length of the line relates to the vector's amplitude.

The dot product of two vectors gives scalar quantity while the cross product gives a vector quantity.

Now,

In option (B) ;

a Х (b . c) now here b . c is a scalar quantity and we can not cross multiply a scalar with a vector.

In option (D) ;

(a.b) Χ (c.d) where we cannot multiply two scalars by cross product.

In option (E);

a.(b.c) we can not multiply two scalars by the dot product.

Hence "The dot product of two vectors gives scalar quantity and between scalar quantity, we can not apply any product".

The given question has a missing option which is given below,

Answer:

18

Step-by-step explanation:

116-98

so sorry if its incorrect

Answer:

34 degrees

Step-by-step explanation:

ahahah okay this is fun

so what you should do here is extend the line that passes through the 116 and 98 degree angle so that it passes the other parallel line.

It makes a triangle doesn't it

One of the angles is supplementary to 98, so 180-98 = 82 degrees.

Another one of the angles is the opposite angle to the supplementary angle of 116 (remember your line-intersecting-parallel-lines angles), therefore 180-116 = 64 degrees

The last angle of that triangle is the opposite to angle 4, and you can find that using the other two angles of the triangle we made earlier, which you get 180-82-64 = 34 degrees

m= -1

Step-by-step explanation:

-4m+5+2m = 3-4m
=> -4m+2m+4m = 3-5
=> 2m = -2
=> m = -2/2 = -1

Answer:

m = -1

Step-by-step explanation:

-4m + 5 + 2m = 3 - 4m

Add up light terms

-2m + 5 = 3 - 4m

Subtract 3 from both sides.

-2m + 2 = -4m

Add 2 to both sides.

2 = -2m

Divide both by -2

Final Answer: m = -1

Step-by-step explanation:

I used Desmos to get a visual representation to help.

The equation y = 4x + 6 has a y - intercept at (6,0).

The equation y = 4x + 2 has a y - intercept at (2,0) and passes through (1,6).

Hope this helps!

The value of  B = 2 when a line, y=mx+b, passes through the point (1, 6) and is parallel to y=4x+6.

The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.

The equation y = 4x + 6 has a y - intercept at (6,0).

The equation y = 4x + 2 has a y - intercept at (2,0) and passes through (1,6).

Therefore the value of  B = 2 when a line, y=mx+b, passes through the point (1, 6) and is parallel to y=4x+6.

Step-by-step explanation:

You would use the Pythagorean Theorem: [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

The a and b is the legs and the c is the hypotenuse

So when you fill it in you get [tex]2^{2}[/tex] + [tex]5^{2}[/tex] = [tex]c^{2}[/tex]

continue to solve the equation 4+25= [tex]c^{2}[/tex]

29 = [tex]c^{2}[/tex]
