Help me with this please

Answer:

Step-by-step explanation:

For the first one, I believe you would need to use a rotation matrix; to rotate 90º counterclockwise, the matrices would look like ; you would then multiply those out. A reflection across the x-axis would be changing the sign of f(x) (from negative to positive or positive to negative), a reflection across the y-axis would be changing the sign of x, translation a units to the right would be subtracting a from x, translation b units up would be adding b to x. Rotation of 180º about the origin would be the same format as the first matrix, except it would be cos180 and cos0 on the top and sin180 sin0 on the bottom. Reflection across the y-axis would be changing the sign of x again.

OR

1. We know that, 'Translation shifts the figure in any direction'.

As, the function f(x) is translated 'a' units to the right, the new form of function is f(x-a).

Again, the function is translated 'b' units up, the final form of the function is f(x-a)+b.

2 and 3. We know that, ' Reflection flips the image over a line'.

As the function g(x) is reflected over y-axis, the new form of the function is g(-x).

As the function h(x) is reflected over x-axis, the new form of the function is -h(x).

4 , 5 and 6. We know that, 'Rotation turns the image around a point to a certain degree'.

Let us assume the function to be a point (x,y).

As the function is rotated by 90° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{90}R

90

(x,y) = ( -y,x ).

As the function is rotated by 180° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{180}R

180

(x,y) = ( -x,-y ).

As the function is rotated by 2700° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{270}R

Answer:

x = 35.1 degrees

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj/ hyp

cos x = 27/33

Take the inverse cos of each side

cos ^-1 ( cos x) = cos ^-1(27/33)

x =35.09680123

To the nearest tenth

x = 35.1 degrees

Answer:

x=35.1

Step-by-step explanation:

cos(x)=[tex]\frac{27^{2}+33^{2}-360 }{2(27)(33)}[/tex]

x=35.1(correct to the nearest tenth)

Answer:

(-2, 3)

Step-by-step explanation:

First solve one equation for y:

[tex]-2x+y=7\\y=7+2x[/tex]

Now we can substitute this equation into the other one:

[tex]3x+7+2x=-3[/tex]

Solve for x:

[tex]x=-2[/tex]

Now substitute this value into the equation [tex]y=7+2x[/tex]:

[tex]y=7+2x(-2)[/tex]

Solve for y:

[tex]7=3[/tex]

Now your solution is (-2,3)

Answer:

m=E/c².

Step-by-step explanation:

Transposing the formula

E=mc²

we divide both sides by c² then cancel out where necessary so m would stand alone

E/c²=mc²/c²

cancelling c² on the right hand side, equation becomes

m= E/c²

Step-by-step explanation:

Calculate the amount of people on both sides.

32% preferred cats

32% of 800

0.32 × 800 = 256 people

27% preferred dogs

27% of 800

0.27 × 800 = 216 people

So 256 people preferred cats and 216 people preferred dogs.

256 - 216 = 40 people

40 more people preferred cats than preferred dogs

40 people preferred cats more than preferred dog.

Percentage is a measurement to find value of given number out of hundred.

Given that,

Total number of people participated in survey = 800.

Percentage of people who preferred cats = 32%,

And percentage of people who preferred dogs = 27%.

The percentage of  people who preferred cats more than preferred dogs

= 32 - 27

= 5 %

The number of people preferred cats more than preferred dogs

= 800 x 5/100

= 40.

There are 40 more people preferred cats than dog.

Answer:

(7z-3)(z-5)

Step-by-step explanation:

7z^2-38z+15

(7z-3)(z-5)

Answer:

(z - 5)(7z - 3)

Step-by-step explanation:

Given

7z² - 38z + 15

Consider the product of the factors of the coefficient of the z² term and the constant term which sum to give the coefficient of the z- term

product = 7 × 15 = 105 and sum = - 38

The factors are - 35 and - 3

Use these factors to split the z- term

7z² - 35z - 3z + 15 ( factor the first/second and third/fourth terms )

= 7z(z - 5) - 3(z - 5) ← factor out (z - 5) from each term

= (z - 5)(7z - 3) ← in factored form

Answer:

m∠JKP = 31.5°

Step-by-step explanation:

Incenter of a triangle is the point where all the bisectors of interior angles intersect each other.

JN is the angle bisector of ∠KJL.

Therefore, m∠KJN = m∠LJN

(7x - 6) = (5x + 4)

7x - 5x = 6 + 4

2x = 10

x = 5

m∠KJN = (7x - 6)

            = 7(5) - 6

            = 35 - 6

            = 29°

In ΔKJN,

m∠JKN + m∠KNJ + m∠NJK = 180°

m∠JKN + 90° + 29° = 180°

m∠JKN = 180°- 119° = 61°

Since KO is the angle bisector of ∠JKN,

m∠JKP = [tex]\frac{1}{2}(\angle JKN)[/tex]

            = [tex]\frac{1}{2}(61)[/tex]

            = 30.5°
