The expression represents the difference quotient of the function f(x) = 13-5x/4 for all nonzero values of h is ( 1 / 4). The correct option is A.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given function is f(x) = 13-5x/4. The value of the expression will be calculated as below:-

E = 13-5x/4

Put the value of x equal to 1.

E = 13-5/4

E = 47-5/4

E = 1/4

Therefore, the value of the expression is (1/4).

Answer:

31/20 miles

Step-by-step explanation:

Given data

Aiden lives 3/4 mile from school

Kaitlyn lives 4/5 as far as Aiden does

Hence Kaitlyn lives

=31/20 miles

Therefore Kaitlyn lives 31/20 miles from school

Answer:

0.064

Step-by-step explanation:

Number of days in a year = 365

Mean rate of false alarm in a year = λ = 365 * 0.2 = 73

Standard deviation, σ = sqrt(λ) = sqrt(73) = 8.54 (for large λ value)

Using the relation :

P(x < 60): (60 - 73) / 8.54

P(x < 60) = - 1.52

P(Z < - 1.52) = 0.06426 (Z probability calculator

Answer:

Distance travelled = 91.61 feet

Step-by-step explanation:

Given the following data;

Diameter, d = 35 inches

Number of revolutions = 10 Rev

To find the distance travelled by the bike;

First of all, we would determine the circumference of the bike's tire, which is circular in shape.

Circumference of circle = πd

Circumference of circle = 35π

Next, we multiply by the number of revolutions to get the distance travelled.

Distance travelled = 35π * 10

Distance travelled = 350π inches

But pie, π = 3.142

Distance travelled = 350 * 3.142

Distance travelled = 1099.7 inches.

In feet;

1 inches = 0.0833 feet

1099.7 inches = x feet

Cross-multiplying, we have;

x feet = 1099.7 * 0.0833

x feet = 91.61 feet

Distance travelled = 91.61 feet

(y2 - y1)           7 - (-1) = 8

----------- >>>

(x2 - x1)           5 - 14 = -9

x always goes first in a coordinate, so

(-9, 8)

Answer:

P = 3s

Step-by-step explanation:

To start with, let's assume that

The perimeter of a triangle is called P

The side of a triangle is called s

Now, by formulae, the perimeter of an equilateral triangle is given as P = 3s. Which is the same as adding up the 3 sides together.

Succinctly put, we can then conclude that if P = 3s, then the perimeter of an equilateral triangle is equal to the lengths of its 3 sides.

A mortgage rate is the interest rate on a mortgage. Mortgage rates are set by the lender and might be fixed, remaining constant during the length of the loan, or variable, varying with a benchmark interest rate. Borrowers' mortgage rates differ depending on their credit profile.

We have,

P = $105, 000

T = 40 year

R = 5.2%

Using

Monthly payment, P = C[i(1+i[tex])^n[/tex]]/[(1+i[tex])^n[/tex]-1]

P = 105,000 [ 0.052/12(1+0.052/12[tex])^{480[/tex]]/[(1+0.052/12[tex])^{480\\[/tex]-1]

P = 105,000 [ 0.00433 (7.8426)] / [7.8426 -1]

P = 105,000 [ 0.03372318] / (6.8426)

P = $249,739

Step-by-step explanation:

Answer:

4x + 33 / 9 = -9

multiply both side by 9;

9x(4x + 33 / 9 )= -9 x(9)

36x + 33 =-81

36x = -81-33

36x = -114

x = (-114)/36

Step-by-step explanation:

Answer:

4x+33/9= -9 (reduce the fraction)

4x+11/9= -9 (move the constant to the.

right)

4x = -9- 11/9

4x = -38/3 (divide both sides by 4)

Answer:6 members swam 10.11Km  during the season

Step-by-step explanation:

Number of members = 6

meters swam by each of the  6 members = 1,685 meters

Total meters swam by  the 6 members  during the season

= 1,685 meters X 6

=10,110 meters

But 1000m  =1km

10,110 m =10.11Km

Answer: 139 feet

Step-by-step explanation:I used tan. Tan(44) = x/140
