The balance after 7 years if you invest 400 at 6 percent compounded monthly is  608.15 units.

You invest 400 at 6 percent compounded monthly . The balance after 7 years can be calculated as follows:

Therefore, using compound interest formula, let's find the amount.

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

where

Therefore,

r = 6 / 100 = 0.06

t = 7 years

p = 400

n = 12

Therefore,

[tex]A = 400(1 + \frac{0.06}{12} )^{12(7)}[/tex]

A = 400(1 + 0.005)⁸⁴

A = 608.15 units

Therefore, the balance is  608.15 units

The taxi can travel a maximum distance of 11 miles if we have at most $10 to spend on the cab ride.

What is distance?

The length of the line connecting two places represents the distance between them. Subtracting the different coordinates will reveal the distance if the two points are on the same horizontal or vertical line.

The formula for measuring distance between two lines, the total length of all a polygon's sides, the perimeter of a polygon on a coordinate plane, the area of a polygon, and many other things are all found in analytical geometry. For instance, we can use the distance formula to find the lengths of a triangle's sides and decide if it is scalene, isosceles, or equilateral.

It is given that, a taxi charges a flat rate of $1.75 plus an additional fee of $0.75 per mile.

We have to find the maximum distance it could travel at most with $10

Let the maximum distance be x miles.

Thus, the fare would be

$(1.75 + 0.75x) = 10

⇒ 0.75x = 8.25

⇒ x = 8.25/0.75

⇒ x = 11

Answer:

Since the slope is undefined, this is a vertical line. Vertical lines have no y-intercept. No y-intercept.

Step-by-step explanation:

hope this helped:)

Answer:

To write the equation of a line in slope-intercept form, we need to first find the slope of the line. The slope is a measure of the steepness of the line, and is calculated as the rise over the run between two points on the line. In this case, we can use the points (-6,-3) and (6,-7) to calculate the slope.

To find the slope, we first need to find the difference between the y-coordinates of the two points, which is -3 - (-7) = 4. We then need to find the difference between the x-coordinates of the two points, which is 6 - (-6) = 12. The slope is then calculated as the rise over the run, which is 4/12 = 1/3.

Once we have the slope, we can use the point-slope formula to write the equation of the line in slope-intercept form. The point-slope formula is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line. In this case, we can use the point (-6,-3) and the slope 1/3 to write the equation of the line.

The equation of the line in slope-intercept form is then y - (-3) = 1/3(x - (-6)), which simplifies to y + 3 = 1/3x + 2. This is the equation of the line that passes through the points (-6,-3) and (6,-7) in slope-intercept form.

Therefore, the correct answer is y + 3 = 1/3x + 2.

The function's standard form equation is equivalent to

y=(1/2)x²+(-7x)+24.

A mathematical expression (equation) that can be used to define and represent the relationship between two or more variables on a graph is known as a quadratic function.

The standard form of a quadratic equation in mathematics is represented by;

ax² + bx + c = 0

y=ax² + bx + c

The information in the table above would then be used to create a set of equations:

The points are (4, 4), (6, 0), (8, 0), (10, 4)

4=a(4)²+b(4)+c

16a+4b+c=4 ------(1)

0=a(6)²+b(6)+c

36a+64b+c=0  ------(2)

0=a(8)²+b(8)+c

64a+8b+c=0  -------(3)

By solving 2 and 3 equations, we get

Eq2-Eq3,

We get b= -14a

By substituting b value in eq2 we get,

36a+6b+c=0

36a+6(-14a)+c=0

35a-84a+c=0

c=48a

By substituting a, b values in eq1 we get,

16a+4(-14a)+48a=4

16a-56a+48a=4

-40a+48a=4

8a=4

a=1/2

Then, b=-14a

b= -7

c=48a

c=24

Now, by substituting these a, b, c values in,

y=ax² + bx + c

y=(1/2)x²+(-7x)+24

By  checking the above equation is correct or not,

We consider the fourth value x=10

When x=10,

y=(100/2)-70+24

y=50-70+24

y=4

From the given table if x=10 then y=4,

So it satisfies with the equation we get.

Therefore, the function's standard form equation is equivalent to

y=(1/2)x²+(-7x)+24.

The mean number of movies that the students saw is 15.

What is mean?

A mean in maths is the average of a data set, found by adding all numbers together and then dividing the sum of the numbers by the number of numbers.

Mean =  Sum of the observations/number of observations

Now it is given that,

Number of students = 5

The number of movies they say = 4, 20, 12, 20, 19

So,

the sum of the number of movies = 4 + 20 + 12 + 20 + 19 = 75

Hence,

Mean = sum of the number of movies / Number of students

⇒Mean = 75/5

⇒Mean = 15

h(t) = -4.9t² + v(0)t + h(0).

In which:

From the graph, the initial height is given as follows:

h(0) = 6.

When t = 4, h = 2.5, hence the initial velocity is obtained as follows:

2.5 = -4.9(4)² + 4v(0) + 6

4v(0) = 2.5 - 5 + 4.9(4)²

4v(0) = 75.9

v(0) = 75.9/4

v(0) = 18.975.

Then the position function is of:

h(t) = -4.9t² + 18.975t + 6.

The velocity function is the derivative of the position, hence:
