The length of the actual hotdog is 15 cm

The graph that completes the question is added as an attachment

The length of the hotdog in the figure is given as

Length = 9 units

The scale is given as

Scale: 6 units = 10 cm

So, we have

6 * 9 units = 10 * 9 cm

Divide both sides by 6

So, we have

9 units = 15 cm

Substitute 9 units = 15 cm in Length = 9 units

Length = 15 cm

Hence, the length of the actual hotdog is 15 cm

If two trains going in opposite directions leave at the same time and train b travels 10 mph faster than train a and in 7 hours the trains are 630 miles apart, then the speed of the faster and slower train is equal to 50mph and 40mph respectively.

The speed of each train can be determined by using an algebraic

expression.

As one train travels 10 miles per hour faster than the other, consider x to be the speed of the slower train. In this case, the algebraic expression to find the speeds of each train can be given as,

7x + 7(x + 10) = 630

7x + 7x + 70 = 630

14x = 630 - 70

14x = 560

x = 560 ÷ 14

x = 40 mph

Therefore, x + 10 = 40 mph + 10 mph = 50 mph

Hence, the speed of the faster train is 50 mph and the speed of the slower train is 40mph.

Lines and mare perpendicular is The same result is obtained by reflecting Q over the Line M as well as rotating Q 180 degrees using the center P.

As a reminder, perpendicular lines are those that cross at a 90-degree angle. Two non-vertical lines are said to be perpendicular when they are in the same plane and intersect at a right angle.

The axes of the coordinate plane, or the horizontal and vertical lines, are simply perpendicular to one another. Additionally, the slopes of the parallel lines have negative reciprocal slopes.

Since Lines L and M are perpendicular lines, or lines that meet at a right angle (90°), rotating Q 180 degrees using the center P has the same result as reflecting Q across Line M.

Q will therefore be identical to reflecting Q over any of the perpendicular lines when rotated 180 degrees from the center.

∠2 = 85°

∠3 = 95°

∠4 = 85°

∠5 = 36°

∠6 = 49°

∠7 = 106°

We are given different angles. Thus;

∠3 will be equal to 95° because of the definition of vertically opposite angles.

∠4 = 180° - 95° because sum of angles on a straight line is equal to 180°. Thus;

∠4 = 85°

∠2 = ∠4 = 85° because they are both vertically opposite angles.

∠5 = 180° - 144° because sum of angles on a straight line is equal to 180°.  Thus; ∠5 = 36°

∠7 = 180° - (38° + 36°) because sum of angles in a triangle is equal to 180°. Thus; ∠7 = 106°

Sum of angles in a quadrilateral is 360°. Thus;

∠1 = 360 - (90 + 144 + 85)

Domain and range is nothing but the sets of all the x-coordinates and all the y-coordinates of ordered pairs, respectively, are the domain and range of a relation. For instance, if the relation is R ={(1, 2), ( 2, 2), ( 3,3 ), ( 4, 3)}

Domain is the set of all x-coordinates with values of {1, 2, 3, 4}.

The set of all y-coordinates in the range is equal to {2, 3}.

Domain and range for the function is

Domain is (-[tex]\infty\\[/tex],[tex]\infty[/tex]),{x|x∈R}.

range is [-9,[tex]\infty[/tex]),{y|y≥-9}

Step-by-step explanation:

Company A:

The recursive formula is, aₙ=aₙ₋₁+4,000, where a₁=42,000

Company B:

The recursive formula is, aₙ₊₁=(1+0.09) x aₙ, where a₁= 42,000

I'm sure she should go for company B, in the long run, she would make much more money. This is proven because company a is increasing using an arithmetic sequence; based on this all they're doing is adding 4,000. But company B is increasing at a percentage of 9 after a while that can really amount to a lot.

Hope this helps, if you are still confused don't hesitate to ask :))

Josie's pay [tex]a_n[/tex] from company A in the [tex]n[/tex]-th year is given recursively by

[tex]\begin{cases} a_1 = 42000 \\ a_{n+1} = a_n + 4000 & \text{for } n\ge1 \end{cases}[/tex]

while her pay [tex]b_n[/tex] from company B is

[tex]\begin{cases} b_1 = 42000 \\ b_{n+1} = 1.09 b_n & \text{for } n \ge1 \end{cases}[/tex]

From these recurrences, we have

[tex]a_2 - a_1 = 4000[/tex]

[tex]a_3 - a_2 = 4000[/tex]

[tex]a_4 - a_3 = 4000[/tex]

and so on - this is just confirming that the pay from company A increases at flat rate of $4000 each year.

Similarly,

[tex]b_2 = 1.09 b_1 = 45780 \implies b_2 - b_1 = 3780[/tex]

[tex]b_3 = 1.09 b_2 \approx 49900 \implies b_3 - b_2 \approx 4120[/tex]

[tex]b_4 = 1.09 b_3 \approx 54391 \implies b_4 - b_3 \approx 4491[/tex]

and we see here that [tex]b_n[/tex] increases at a larger rate year. In only 2 years of working at company B, Josie would be making more money, and the amount by which her salary increases each year is also increasing.

Assuming Josie hopes to make more money, invest in her future, etc, she should take the offer from company B.

Inverse of the give function F(x) = √2 x + 1 is F⁻¹(x) = ( x - 1 ) / √2

Given is a function of x, F(x) = √2 x + 1

These question can be solved by following 4 easy steps

Step 1 : Switch the F(x) with the variable y

This implies, F(x) = √2 x + 1 becomes y = √2 x + 1

Step 2 : Interchange the variable x and y in the above obtained equation

This implies, from the equation y = √2 x + 1, we get

x = √2 y + 1

Step 3 : Solve the new obtained equation for y

This implies, we have to simplify the equation by rearranging the terms to get the equation in terms of the variable x.

x = √2 y + 1

=> x - 1 = √2 y

=> √2 y = x - 1

=> y = ( x - 1 ) / √2

Hence we obtain the required equation.

Step 4 : Switch the variable y with F⁻¹(x)

This implies, y = ( x - 1 ) / √2 becomes F⁻¹(x) = ( x - 1 ) / √2

Therefore, we get the inverse of the given function F(x) = √2 x + 1 as F⁻¹(x) = ( x - 1 ) / √2.
