I’m not really sure what to choose..

Answer:

a = 100 + 45t

Step-by-step explanation:

$100 is a one time addition so it will be a constant

100

$15 is added three times a month, so $45 a month

t stands for months as shown in the question

100 + 15(3)t

100 + 45t

10% more than 6.16 is 6.776.

Two numbers, whose sum is 5.036, are 3.407 and 1.629.

Decimals numbers are numbers containing wholes and parts separated by a decimal point ".".

In adding or subtracting decimal numbers, first is to align the decimal point of the decimal numbers. Add/subtract the digits from right to left.

If we have two numbers, one number has a 4 in the tenths place and a 7 on the thousandths place, the second number has a 1 in the ones place and and an 2 in the hundredths place, and their sum is 5.036, we can write that as:

 _ . 4 _ 7

+ 1 . _ 2 _

 5 . 0 3 6

7 and 9 when added will give a sum of 16.

 _ . 4 _ 7

+ 1 . _ 2 9

 5 . 0 3 6

Since there is 1 from 16 earlier, 1 and 2 when added will give a sum of 3.

 _ . 4 0 7

+ 1 . _ 2 9

 5 . 0 3 6

4 and 6, when added will give a sum of 10.

 _ . 4 0 7

+ 1 . 6 2 9

 5 . 0 3 6

Since there is 1 from 10, 1 added to 1 and 3 will give a sum of 5.

 3 . 4 0 7

+ 1 . 6 2 9

 5 . 0 3 6

Hence, the two numbers are 3.407 and 1.629.

Answer:

Step-by-step explanation:

Give three functions f(x), g(x), and h(x), you want various combinations of them.

If ✧ represents some generic math operator, we often use the notation ...

  (f ✧ g)(x)

as a shorthand way to write ...

  f(x) ✧ g(x)

The usual meaning of the operator applies.

The three given functions are ...

The definitions are substituted for the function name:

  (h -f)(x) = h(x) -f(x) = x² -(x -2)

  (h -f)(x) = x² -x +2

  (f +h)(x) = f(x) +h(x) = (x -2) +x²

  (f +h)(x) = x² +x -2

  (g -f)(x) = g(x) -f(x) = (2x +3) -(x -2) = 2x +3 -x +2

  (g -f)(x) = x +5

  (g +h)(x) = g(x) +h(x) = (2x +3) +x²

  (g +h)(x) = x² +2x +3

The correct statement is  BC equals to AC times CE all over CD.

We have, If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally. this is known as the triangle proportionality theorem.

Given, DE and AB are parallel

So,   [tex]\frac{BC}{CE} =\frac{AC}{CD}[/tex]

[tex]BC = \frac{AC\times CE}{CD}[/tex]

Therefore in statement form we say that BC equals to AC times CE all over CD.

Answer:

^two dimentional figure with algebra^

the perimwter from triangle is:

s1 + s2 + s3

ok, enter:

s1 + s2 + s3= 369

x + (8x -5) + 2x = 369

x + 8x - 5 + 2x = 369

group according to the same variable

(x + 8x + 2x) + (-5)=369

11x + (-5)=369

11x - 5= 369

11x = 369 + 5

11x =374

x =374 : 11

x = 34

ok, subtituted:

s1= x

=34 feet

s2= 8x - 5

=8(34) - 5

=272 - 5

=267 feet

s3= 2x

Answer:

16 miles

Step-by-step explanation:

Given that :

1 unit = 3 miles

High School = (2, 4)

Stadium = (7, 6)

Approximate distance between high school and stadium :

Distance between High school and Stadium

x1 = 2 ; y1= 4 ; x2 = 7 ; y2 = 6

Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Distance = sqrt((7 - 2)^2 + (6 - 4)^2)

Distance = sqrt((5^2 + 2^2))

Distance = sqrt(25 + 4)

Distance =5.3851648 units

1 unit = 3 miles

Approximate Distance in miles :

3 * 5.3851648 = 16.155494

Approximate distance = 16 miles

Domain f(x) = 23, 7, -9 for range of { -7, 1, 9}

The domain is f(x) = -2x + 9, and the range of the function is {-7, 1, 9}

To find the domain of the function we have to put the value of x as -7, 1, and 9.

Put x = -7 we have

f(x) = -2x + 9

     = -2(-7) + 9

     = 14+9

     = 23

Now x = 1

f(x) = -2(1) + 9

     = -2+9

     = 7

Now x = 9

f(x) = -2(9) + 9

     = -18 + 9

     = -9

Therefore we get the domain of function as 23, 7, -9 for the range {-7, 1, 9}.

The fourth-order accurate finite difference approximation is:

u00(x) = c−2u(x − 2h) + c−1u(x − h) + c0u(x) + c1u(x + h) + c2u(x + 2h) + O(h4).

Compute the coefficients using the matlab code fdstencil.m and check that they satisfy the system you determined in part (a).

Test this finite difference formula to approximate u

00(1) for u(x) = sin(2x) with values of h from the array hvals = log space(-1, -4, 13). Make a table of the error vs. h for several values of h and compare against the predicted error from the leading term of the expression printed by  fdstencils.

You should observe the predicted accuracy for larger values of h. For smaller values, numerical cancellation in computing the linear combination of u values impacts the accuracy observed.
