Which of these figures has rotational symmetry?

Answer:

Step-by-step explanation:

you want a line with slope = -1/2

So, using the point-slope form of the line,

y-7 = -1/2 (x+4)

y = -1/2 x + 5

Hard to tell what your choices are ...

Problem 1

-----------------------------------

Explanation:

The scale factor is DE/AB = 1.34/2 = 0.67

This means DE is 67% of the length of AB

Or you could say that DE = 0.67*AB

This means that

DF = 0.67*AC

DF = 0.67*4

DF = 2.68

Side note: AC and DF are the first and last letters of ABC and DEF respectively. This is why AC and DF correspond together.

===========================================================

Problem 2

-----------------------------------

Explanation:

We'll use the same scale factor to find EF

new side = (scale factor)*(old side)

EF = 0.67*BC

EF = 0.67*3

EF = 2.01

Side note: BC and EF are the last two letters of ABC and DEF respectively, so BC corresponds to EF.

Answer:

Step-by-step explanation:

The x-term has even degree so is never negative. The x-term is subtracted from 12, so the maximum value of the function will be found where x=0. That value is 12 -0 = 12.

  f(0) = 12 . . . . absolute maximum

Answer:

The function [tex]f(x)=12-6x^4[/tex] has an absolute maximum value of [tex]12[/tex] and this occurs at [tex]x $\ equals 0.[/tex]

Step-by-step explanation:

The maximum value of this function is at 12, because if you rewrite this function:

The +12 is the k-value (the graph of this function is a parabola) of the vertex form of a quadratic. Just a reminder:

Vertex form of a parabola:

You can see the 12 is the k-value. The k-value of the vertex form is the vertical shift of the parabola, meaning that this parabola is shifted 12 units upwards.

Since the parabola opens down (you can tell by the negative a-value [tex]-6[/tex]), there is a maximum value at the k-value, i.e. the vertical shift.

[tex]f(x)=-6x^4+12[/tex] has an absolute maximum value of [tex]12[/tex].

To find where the maximum value occurs at, the formula:

Tells us the x-value of the vertex of the parabola, whose y-value is the maximum value.

Using our rearranged equation, the a, b, and c-values are:

Plug in the a and c values into the formula to find the x-value of the maximum point:

Therefore, the absolute maximum value of 12 occurs at x = 0.

Answer:

f(10)=342

Step-by-step explanation:

f(10)= 3(10)^2+6(10)-18

complete your exponet first and multiply 6(10)

f(10)=3(100)+60-18

multiply the 3(100)

f(10)=300+60-18

add and subtract all the numbers together

f(10)=342

Answer:

∠EBF = 51°

∠DBE = 17°

∠ABF = 141°

∠EBA = 90°

∠DBC = 107°

∠DBF = 68°

Hope this helps

Answer:

1.

a. m<EBF = 90 - 39 = 51

b. m<EBA = 90

c. m<DBE = 90 - 73 = 17

d. m<DBC = 90 + 17 = 107

e. m<ABF = 90 + 51 = 141

f. m<DBF = 17 + 51 = 68

Answer:

y = 5x.

Step-by-step explanation:

Read the table from top to bottom.  You'll see that each time x increases by 1, y increases by 5.  We know immediately that the slope of this line is m = rise/run = 5/1 = 5.

Using the first point (2, 10), we see that y = 10 when x = 2.  Fit this info into the slope-intercept form of the equation o a straight line:

y = mx + b becomes 10 = 5(2) + b, or b = 0, and the final equation is y = 5x.

Answer:

I would say that shape E  and A has symmetry.

Step-by-step explanation:

The line of symmetry means that on both sides of the shape from the middle part, it is equal. For example, a square has symmetry because it is equal when you split in in half.

If you were to rotate E and A a little, the slice it in half, it is equal on both sides, thus having symmetry.

Answer:

10 i sqrt 2

Step-by-step explanation:

i indicates that it is an imaginary number. this is because 200 is negative.

The simplified form of the given square root number is 10i√2. Therefore, the correct answer is option D.

The given square root number is √-200.

The square root of a number is the inverse operation of squaring a number. The square of a number is the value that is obtained when we multiply the number by itself, while the square root of a number is obtained by finding a number that when squared gives the original number.

Here, 200 = 2×2×2×5×5

Thus, √-200=√-2×2×2×5×5

=2×5×i√2

= 10i√2

Therefore, the correct answer is option D.

Step-by-step explanation:

Complementary angles means that the angles should add up to 90°.

let the complementary angle of 53.8° is x°.

So,

53.8° + x° = 90°.

x° = 90°-53.8°

x = 36.2°

Step-by-step explanation:

Because a trangle have 180 degree inside

Answer:

Step-by-step explanation:

second one - for this one you would do 90 +30 = 120

then take this from 180 to get 60  . so if you can see  that  the shape is an f but that's if you take away the sides with the right angles . the corresponding angle rule (you can see an F shape) means that the angle that i just worked out is the same as angle c so angle c=60

third one - for this one do  70+30  then take this answer away from 180

that angle x

the rule for angle y is the vertically opposite angle rule   - angle s that are vertically opposite are the same  angle y= angle x - same angle
