(100 POINTS!!! NEED HELP, PLEASE HURRY!!) Valerie estimates that a used vehicle will require regular maintenance every 3 months. The average costs for this is $45. The insurance premiums are estimated at $100 per month. She saves $100 per month for tires and unexpected repairs since there is no warranty on the used vehicle. The interest rate is 11% to finance the vehicle. (Interest rates are traditionally higher on used vehicles.) Valerie can afford $400 per month for four years to buy a vehicle. Excluding tax, tag, and title, approximately what is the most Valerie can pay for a vehicle?

Step-by-step explanation:

First, note that the degree of a polynomial is the value of the highest exponent in the polynomial

There will be as many solutions as there are degrees

1.  - 6x − 9y = 2 has degree 1 since x == x¹ so 1 solution

2. [tex]2x^5-x^4+2x^3-6x^2+2x\:+\:4=0[/tex] has degree 5 so 5 solutions

3. [tex]-4x^3 - 10x^2+7x+5[/tex] has degree 3 so 3 solutions

Step-by-step explanation:

a || b means that a is parallel with b.

a ≅ b means a is congruent with b. that mags that if you orient a and b alike and then put them on top of each other, there is nothing that stands out. they perfectly cover each other.

for angles alone this simply means they have the same size.

A true.

when a line (like in this case r) intersects parallel lines (like in this case p and q), then the angles at the intersections must be the same for p and q.

after all, parallel means that both lines emulate each other's behavior exactly - except for the physical location itself.

B in general is not true. it would only be true, if also r || s.

C true. for the same reasons as A.

D true. for the same reasons as A.

Solve for [tex]t[/tex] when [tex]h=0[/tex], given [tex]v_0=0[/tex] and [tex]h_0 = 4[/tex].

[tex]0 = -16t^2 + 4 \implies 16t^2 = 4 \implies t^2 = \dfrac14 \implies t = \dfrac12[/tex]

The slope of the line that is parallel to the given equation is 4

From the question, we are to determine the slope of the equation that is parallel to the given line

The given line is

y = 4x + 4

First, we will determine the slope of the given line

By comparing with the slope-intercept form of the equation of a straight line,

y = mx + b

Where m is the slope

and b is the y-intercept

By comparison,

m = 4

Thus,

The slope of the line is 4

NOTE: If two lines are parallel, their slopes are equal

Hence, the slope is 4

Answer:

The system consists

Step-by-step explanation:

The amount he put into the first account at 2% interest will be $8,000 and into the second account at 7% interest will be $42,000.

Given that,

Amount invested by Alex = $50,000,

Total interest earned = 6.2%,

Now,

Let,

Amount invested at 2% = x,

So,

Amount invested at 7% = (50,000 - x),

So,

According to the question,

7%(50000 - x) + 2%(x) = 6.2% * 50,000

we get,

0.07(50000 - x) + 0.02(x) = 0.062 * 50,000

3500 - 0.07x + 0.02x = 3100

3500 - 0.05x = 3100

We  get,

0.05x = 3500 - 3100

0.05x = 400

x = 8000,

So,

Amount invested at 2% = $8000,

So,

Amount invested at 7% = (50,000 - 8000) = $42,000,

Hence we can say that the amount he put into the first account at 2% interest will be $8,000 and into the second account at 7% interest will be $42,000.

Answer:

It would be A

Step-by-step explanation:

The correct way to find the sum p+q, where p is positive and q is negative, is to start from the point representing p on the number line and move to the left by the magnitude of q.

Let's place the positive number p on the number line, starting from the origin (0) and moving to the right by p units. Now, let's place the negative number q on the number line by moving q units to the left from the origin.

To find the sum p+q, we need to consider the relative positions of p and q. Since p is positive, we have moved to the right on the number line. However, since q is negative, it is also positioned to the left of the origin. To add p and q, we need to consider their magnitudes and the direction they point in.

The correct way to find the sum p+q is to start from the point representing p and then move to the left by the magnitude of q. This corresponds to moving p units to the right and then q units to the left. The endpoint of this combined movement represents the sum p+q on the number line.

Hence the correct option is (a).

The percentage of batteries that last between 1.25 and 5.75 years will be 99.73%.

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is given as

z = (x - μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

One significant manufacturer's batteries are known to have a shelf life that is regularly distributed, with an average life of 3.5 years and a standard deviation of 0.75 years.

The value of the z-score will be

z = (1.25 - 3.5) / 0.75, (5.75 - 3.5) / 0.75

z = -3, 3

The percentage of batteries that last between 1.25 and 5.75 years will be

P(1.25 < x < 5.75) = P(- 3 < z < 3) x 100

P(1.25 < x < 5.75) = 0.9973 x 100

P(1.25 < x < 5.75) = 99.73%

Answer:

  (c)  -19 + x = -21

Step-by-step explanation:

You want the mathematical expression equivalent to the English sentence "a number added to -19 is -21."

Addition is written using the math plus symbol (+).

The English word "is" usually signifies sameness or equality, expressed using the math equal sign (=).

The variable x is often used to represent "a number."

When a number is added to -19, we start with -19, then, using the plus symbol, we add x:

  "a number added to -19"   ⇒   -19 + x

  "is"   ⇒   =

   "-21"   ⇒   -21

So, the translated description is ...

  -19 + x = -21

The extra calories that you are consuming per year is 182,500 calories.

The number of miles that you should walk to burn the extra calories is 1,825 miles.

You are consuming 20 oz of Dr. Pepper each meal. You take Dr. Pepper twice in a day. To determine the total extra calories that is being consumed, multiply the calories consumed per month by the number of times in a day you consume Dr. Pepper and by the number of days in a week.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. The sign used to represent multiplication is ×.

Extra calories consumed in a year = calories per meal x 2 x number of days in a year

250 x 2 x 365 = 182,500 calories

In order to determine the number of miles you have to walk to lose the extra calories, divide the extra calories by the calories lost per mile

Number of miles to walk = 182,500 / 100 = 1825 miles

What is Perimeter of rectangular?

The perimeter of a rectangle is two time the sum of length and width of rectangle.

Given that;

The perimeter of rectangular room = 29 meter

The length of rectangular room is 1.9 times as long as it is wide.

Now, Let the width of rectangular room = x

Then Length of rectangular room = 1.9x

⇒ 29 =  2 (1.9x + x)

⇒ 29 = 2 * 2.9x

⇒ x = 5

Hence, The length of rectangular room = 1.9x

                                                             = 1.9 * 5

                                                             = 9.5 meter

The value of the account is $47226.73.

The compound interest formula is equal to  

A = P( 1 + r/n )^{nt}

where  A is the Final Investment Value, P is the Principal amount of money that is to be invested, r is the rate of interest, t is the Number of Time Periods, and n is the number of times interest is compounded per year.

Now, we have:

t = 21 years

Principal amount, P = $9000

Rate, r = 8% = 0.08 and

n = 12 as a year has 12 months.

Substituting these values in the formula,

[tex]A = P( 1 + \frac{r}{n} )^{nt}[/tex]

A = 9000 × ( 1 + 0.08/12)²⁵²

A = 9000 × ( 1 + 0.0066)²⁵²

A = 9000 × ( 1.0066)²⁵²

A = 9000 × 5.247
