20. Solve for r
T=1+r/n

Answer:

[tex]x=1[/tex] is a critical point of the function [tex]f(x).[/tex]

Step-by-step explanation:

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

Differentiate both sides w.r.t. [tex]x[/tex]

[tex]\Rightarrow f'(x)=2x-2[/tex]

Now, [tex]f'(x)=0[/tex]

[tex]\therefore 2x-2=0[/tex]

[tex]\Rightarrow 2x=2[/tex]

[tex]\Rightarrow x=1[/tex]

Hence, [tex]x=1[/tex] is a critical point of the given function.

Answer:

$292 in fees

Step-by-step explanation:

First, calculate the total payments Jan made over the 4 years

$355 x 4 payments per year x 4 years =  $5,680

Then, calculate the total payments made and subtract the amount of Principal and Interest paid from the total payments made.

$5,680 - $5,388 = $292

$292 is the FEE for the loan

$4,700 is the PRINCIPAL for the loan

$688 is the INTEREST for the loan

Answer:

The answer is 292

Answer:

y= 4/3x - 8.7777777777(reoccurring)

Step-by-step explanation:

ok for perpendicular slopes we use the negative reciprocal of the original slope so -3/4 turns into 4/3. next we take the equation y = 4/3x + b and plug in -1 for x and -10 for y to find B.

Answer:

Yes

Step-by-step explanation:

1/4 = 4/16 because 1/4 of 16 is 4

Also,

1/4 is just a simplified version of 4/16

The answer to whether 1/4 and 4/16 are equivalent fractions is that; Yes, they are equivalent fractions

We have two fractions which are; 1/4 and 4/16

Now, the first fraction is already in simplified form and can't be simplified further. However, the second fraction can be further simplified.

For the second fraction which is 4/16, the numerator and denominators have a common term which is 4. Thus, we can factor it out to get;

(4/4) * (1/4)

4/4 =1 and so we see that 4/16 can be reduced to the first fraction and so they are the same.

Answer:

Step-by-step explanation:

We'll make a table for this since we have 2 different trains for which we have formulas. We'll use the distance = rate * time formula, but we have to use it twice because we have 2 trains, then we have to come up with an equation that incorporates both of the distances of the 2 trains to come up with a time. Easy.

                      d           =          r         *          t

East train

West train

Now we can fill in. We know that the rate of the east train is 105 and the rate of the west train is 85, so we fill that in:

                     d           =            r         *           t

East train                               105

West train                               85

The time is what we are looking for, so that is the unknown for each train:

                        d          =          r         *           t

East train                               105                   t

West train                               85                   t    

Since the formula is d = rt, we will multiply the rates of each times the time of each and fill in accordingly:

                              d           =             r             *           t

East train          105t                      105                         t

West train           85t                       85                        t

Here's an illustration to the best of my abilities in this forum:

<------------------------------|----------------------->

            85t                          105t

|----------------------456 miles-------------------|

The illustration is supposed to show you that the distance between the trains (456 miles) is found by adding the 2 distances together and solving for t:

85t + 105t = 456

190t = 456 so

t = 2.4 hours

Step-by-step explanation:

Hey there!!!

Here, ABCD is a parallelogram.

We know that the one property of a parallelogram is:

So,

3x-10° = x+45°

or, 3x - x = 45°+10°

2x = 55°

[tex]x = \frac{55}{2} [/tex]

Therefore the measure of angle x is 27.5°.

Hope it helps....

Step-by-step explanation:

Let the number be x

1 2/3% × x = 4.75

5/3% × x = 4.75

(5/3)/100 × x = 4.75

5/3 × 1/100 × x = 4.75

5x/300 = 4.75

5x = 300 × 4.75

x = (300 × 4.75)/5

x = 1425/5

x = 285

Answer:

95 city and 175 highway miles.

Step-by-step explanation:

The driver gets 20 mpg in city, and 28 mpg on the highway.

An equation that could be written is

20x+28y=270

This equation accounts for the distance traveled.

x+y=11

This equotion accounts for how many gallons were driven.

Multiply the bottom equation by 20, so you can solve the set of equations.

20x+28y=270

20x+20y=220

subtract them

8y=50

y=6.25

now plug this back into x+y=11

x+6.25=11

x=4.75

Now 4.75×20=95 city miles and 6.25×28=175 highway miles.

Answer:

[tex]-9x[/tex]

Step-by-step explanation:

Add/Subtract the terms:

[tex]-3x-6x=-9x[/tex]

Answer:

[tex]y = 9x + 7[/tex]

Step-by-step explanation:

To solve for y, our goal is to get it isolated on one side of the equation.

[tex]4y - 36x = 28[/tex]

Let's add [tex]36x[/tex] to both sides of the equation.

[tex]4y = 36x + 28[/tex]

Now divide both sides by 4.

[tex]y = 9x + 7[/tex]

Hope this helped!

Answer:

4y-36x = 28........... :4

y-9x = 7

y = 7+9x or y = 9x+7

Answer:

d(3) = - 25

Step-by-step explanation:

Using the recursive formula with d(1) = 3, then

d(2) = d(1) - 14 = 3 - 14 = - 11

d(3) = d(2) - 14 = - 11 - 14 = - 25

Thus the 3 rd term in the sequence is - 25

Answer:

-2.

Step-by-step explanation:

The origin is (0, 0). So:

The slope = (-2 - 0 )/  (1 - 0)

= -2/1

= -2.

Given that:

The company uses its cargo vans to deliver packages to locations at a 75-mile radius  from the warehouse.

If delivery location is within 8 miles of the delivery boundary, a cargo van will still be used.

To find: The inequality to represent the instances when a vehicle other than a cargo van is used.

Solution:

Let x is the distance of a location from the warehouse.

Cargo van will be used if delivery location is within 8 miles of the delivery boundary.

Minimum distance for delivery = 75-8 = 67 miles.

Maximum distance for delivery = 75+8 = 83 miles.

So, the company  uses cargo vans for any distance in the range 67 miles to 83 miles. So,

[tex]67\leq x\leq 83[/tex]

Therefore, the required inequality is [tex]67\leq x\leq 83[/tex].
