Answer:

h(x)=2x-1

Step-by-step explanation:

The Given function is

f(x) =2*(0.35)* x

→y=0.7* x→Pre image

The line passes through first and third quadrant.

it is equation of straight line passing through origin and slope =0.7.

When this line is reflected over y axis , the equation of new line will be

→y= - 0.7 x⇒image

Slope of image will be = -0.7

The Image passes through Second and fourth Quadrant.

From (0, 0), the points A and D in the graph are at (-1, -1) and (2, -1) respectively.

Since the scale factor is 2, every point will be moved twice a distance in both directions. (x and y).

So, multiplying both coordinates by 2, we will get the dilated points.

Hence, A' will be at (2 × (-1), 2 × (-1)) = (-2, -2) and D' will be at (2 × 2, 2 × (-1)) = (4, -2).

Using circle theorem, If MN has a length of π cm, the length of LM is   π√3 cm

ΔMON = equilateral triangle.

Equilateral triangle has all its sides and angle equal to each other.

Therefore,

MN = π

Hence,

ON = MN = OM = π

ON = radius of the circle

Therefore,

LN = π+ π = 2π

Using circle theorem,

∠LMN = 90 degrees

Therefore, using Pythagoras theorem,

LM² = (2π)²- π²

LM² = 4π² - π²

LM = √3π²

Step-by-step explanation:

A function that fits the following points (0,5), (2,-13) is y = 9x + 5

The equation of a line in slope-intercept form is expressed as;

y =mx +b

where;

m is the slope

b is the intercept

Given the following coordinates (0,5), (2,-13)

Slope = -13-5/2-0
Slope = -18/-2

Slope = 9

Since the y-intercept is b = 5, hence the equation of the line will be y = 9x + 5

The sample size needed to provide a margin of error of 2 or less with a .95 probability when the population standard deviation equals 11 is 116.

Given margin of error of 2,probability of 0.95 and standard deviation is 11.

We have to calculate the sample size needed to provide a margin of error of 2 or less with a 0.95 probability when the population standard deviation of 11.

We know that the margin of error is the difference between the calculated values and actual values.

Margin of error=z*σ/[tex]\sqrt{n}[/tex]

where z is z value ,σ is standard deviation ,n is the sample size.

First we have to calculate the z value for the corresponding p value which is given of  0.95. We assume that the test is two tailed. z value is 1.96.

Now put the value of z , σ, n and margin of error in the formula of margin of error to get the value of n which is sample size.

2>=1.96*11/[tex]\sqrt{n}[/tex]

[tex]\sqrt{n}[/tex]>=(1.96*11)/2

[tex]\sqrt{n}[/tex]>=10.78

By squaring both sides we get,

n>=116.2064

Hence the sample size which is needed to provide a margin of error of 2 or less with a 0.95 probability when the population standard deviation equals 116.

k = √(49 - 12√5)

= √(45 + 4 - 2 √180)

= √45 - √4

= 3 √5 - 2.

So, k + 2 = 3 √5 - 2 + 2 = 3 √5.

Answer:

k + 2 = 3√5

Explanation:

[tex]\sf Given: k = \sqrt{49 - 12\sqrt{5} }[/tex]

[tex]\sf \rightarrow k = \sqrt{49 - 12\sqrt{5} }[/tex]

step 1: breakdown

[tex]\sf \rightarrow k = \sqrt{4 + 45- 2 \times 2 \times 3 \sqrt{5} }[/tex]

step 2: rewrite 45 = (3√5)²

[tex]\sf \rightarrow k = \sqrt{4 + (3\sqrt{5})^2 - 2 \times 2 \times 3 \sqrt{5} }[/tex]

step 3: rearrange as per a² -2ab + b² = (a - b)²

[tex]\sf \rightarrow k = \sqrt{ (3\sqrt{5})^2 - 2 \times 3 \sqrt{5} \times 2 +2^2}[/tex]

step 4: comparing, here: a = 3√5, b = 2

[tex]\sf \rightarrow k = \sqrt{ (3\sqrt{5} -2)^2}[/tex]

step 5: simplify √a² = a

[tex]\sf \rightarrow k = 3\sqrt{5} -2[/tex]

SInce you notice there is movies with an 8 difference....

Answer:

4 horror movies

Step-by-step explanation:

This seems to be a problem related to ratios. We are given that, for every 24 kids' movies, there are 32 horror movies. We need to figure out how many horror movies there would be if there were just 3 kids' movies. We can set up an equation using proportions:

[tex]\frac{24}{32}=\frac{3}{x}[/tex]

We don't know how many horror movies there would be so we can let this quantity equal x. Now, we can cross multiply and solve for our unknown:

[tex]24x = 3*32\\24x = 96\\x = 4[/tex]

This means that there are 4 horror movies

Answer:

  x = -5.6

Step-by-step explanation:

Using the given coordinates in the given slope formula, we have ...

  (y2 -y1)/(x2 -x1) = -8/5 . . . . . using the given slope

  (4 -x)/(3 -9) = -8/5 . . . . substituting (9, x) for (x1, y1) and (3, 4) for (x2, y2)

Multiplying by 30, we have ...

  5(x-4) = -48

  5x -20 = -48 . . . . eliminate parentheses

  5x = -28 . . . . . . . . add 20

  x = -5.6 . . . . . . . . divide by 5

Additional comment

In the attachment, we have written the point-slope equation of the line, then found the point on that line that has a x-coordinate of 9. We see the y-coordinate of that point is -5.6, as computed above.

If you swap the points (x1, y1) and (x2, y2), then the slope equation ends up with fewer minus signs to handle.

Answer:

Step-by-step explanation:

These equations are known as slope-intercept equations.

Slope-intercept equation are a type of linear equation.

The slope-intercept format is: y = mx + b

Because there are two equations, this would be a system of equations.

So, to figure this out, we need to use the substitution method.

_____________________________________________

Problem:

Solve y=x−2;y=3x+5

Solution:
Step: Solve y=x−2 for y:

Step: Substitute x-2 for y in y = 3x + 5:

y = 3x + 5

x - 2 = 3x + 5

x−2+−3x=3x+5+−3x(Add -3x to both sides)

−2x−2=5

−2x−2+2=5+2(Add 2 to both sides)

−2x=7

-2x/-2 = 7/-2 (Divide both sides by -2)

x = -7/2

Step: Substitute -7/2 for x in y = x - 2:

y = x - 2

y = -7/2 - 2

y = -11/2(Simplify both sides of the equation)

Answer:

x = -7/2 and y = -11/2

The point (-2, 5) is not included in the solution area

The system of inequalities is given as:

y > 5x + 5

y > -2x+1

See attachment for the graph.

Since the inequalities use the greater than symbol, then the lines of the inequalities would be a dotted line and the upper part would be shaded

The point is given as:

(-2, 5)

The point (-2, 5) is not in the shaded area of the system of inequalities

Hence, the point is not included in the solution area

Mathematically, we have:

5 > 5 * -2 + 5 ⇒ 5 > -5 --- true

5 > -2 * -2 +1 ⇒ 5 > 5 --- false

Since both inequalities are not true, then the point is justified

The measures of the remaining side lengths of the triangle, AC and BC is 72 units and 31 units respectively.

B = 180 - (25 + 55)

B = 100⁰

sin (B)/AC = sin (C)/AB

sin (100)/AC = sin (55)/60

sin (100)/AC = 0.01365

AC = sin (100) / (0.01365)

AC = 72 units

sin (A)/BC = sin (C)/AB

sin (25)/BC = sin (55)/60

sin (25)/BC = 0.01365
