Answer:

$8960

Step-by-step explanation:

Given

principal =  $8000

rate= 3%= 0.03

time = 4 years

Required

the final amount, we assume that this is a simple interest investment.

Step two:

[tex]A= P(1+rt)\\\\A=8000(1+0.03*4)\\\\A=8000(1+0.12)\\\\A=8000*(1.12)\\\\A=8960[/tex]

The final amount in the account is $8960

Step-by-step explanation:

When we say sum we are referring to addition.

And a number and a variable(letter) can't be added. So the sum of 8 and t can't be added.

The sum of 8 and t is;

8+t

When we talk about product or finding the product of a number we are referring to the number we get after multiplying two or more numbers.

And note that with multiplication, a number and a variable(letter) can be multiplied.

The product of 5 and b is;

5×b=5b

Answer:

[tex]T_n = -97n[/tex]

Step-by-step explanation:

The actual sequence is: -97, -194, -291, -388

Required

Determine the nth term

nth term of an arithmetic progression is:

[tex]T_n = T_1 + (n - 1)d[/tex]

Where

[tex]T_1 = First\ Term = -97[/tex]

[tex]d = Common\ Difference = -194 - (-97) =-97[/tex]

So:

[tex]T_n = T_1 + (n - 1)d[/tex] becomes

[tex]T_n = -97 + (n - 1) * -97[/tex]

[tex]T_n = -97 -97n + 97[/tex]

Collect Like Terms

[tex]T_n = -97n + 97-97[/tex]

[tex]T_n = -97n[/tex]

Hence, a term of the sequence is:

[tex]T_n = -97n[/tex]

Answer: total cost of the estimated  items = $76

Step-by-step explanation:

 Step 1

Rounding up each item to the next dollar

Book 1 = $8.95 ≈ $9.00

Book 2 = $11.95≈ $12.00

Book 3 = $22.25≈$22.00

Book 4 =   $24.95≈$25.00

Calendar = $8.25 ≈$8.00

Step 2

The total estimated cost of items in Emma's shopping basket =$9.00+$12.00+$22.00+$25.00+$8.00

=$76  which did not exceed the amount of bookstore gift card of $80 sent by her grandmother.

Answer: 78$

Actual                            Estimate

$8.95 --------------------------$9.00

$11.95--------------------------$12.00

22.25--------------------------$23.00

$24.95------------------------$25.00

 $8.25--------------------------$9.00

Then add the estimate numbers to get $78

Answer:

4/3 or 1.3

Step-by-step explanation:

y= 3x-4

To find x- intercept/zero, Substuite y=0.

0= 3 x -4

Move the variable to the left-hand side and change its sign

-3x= -4

Divide both sides of the equation by -3

x= 4/3

(1.3 as a decimal)

Step-by-step explanation:

((3•5x2) +  7x) -  2

Factoring  15x2+7x-2

The first term is,  15x2  its coefficient is  15 .

The middle term is,  +7x  its coefficient is  7 .

The last term, "the constant", is  -2

Step-1 : Multiply the coefficient of the first term by the constant   15 • -2 = -30

Step-2 : Find two factors of  -30  whose sum equals the coefficient of the middle term, which is   7 .

     -30    +    1    =    -29

     -15    +    2    =    -13

     -10    +    3    =    -7

     -6    +    5    =    -1

     -5    +    6    =    1

     -3    +    10    =    7    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -3  and  10

                    15x2 - 3x + 10x - 2

Step-4 : Add up the first 2 terms, pulling out like factors :

                   3x • (5x-1)

             Add up the last 2 terms, pulling out common factors :

                   2 • (5x-1)

Step-5 : Add up the four terms of step 4 :

                   (3x+2)  •  (5x-1)

            Which is the desired factorization

Answer:

(5x-1)(3x+2)

Answer:

B

Step-by-step explanation:

I looked it up

The line with equation y=−2x+7 is rotated 90° clockwise about the origin, the coordinates of the image of its y-intercept is D  (−7,0).

The intersection of the graph of the function with the y-axis gives y-intercept of that function.

The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x)

At y-axis, we've got x = 0, so putting it will give us the y-intercept.

Thus, y-intercept of y = f(x) is y = f(0)

To find the y-intercept of the line y=-2x+7. When x=0 we have that y=-2·0+7, y=7,

then point (0,7) is the y-intercept.

When we rotate this line 90° clockwise about the origin, then point (0,7) will be placed on the x-axis in positive x-direction.

Rotation preserves the distances, then the coordinates of the image are (7,0).

The correct choice is D  (−7,0).

Answer: 4.126 km

Step-by-step explanation:

First, We have to find total span of both bridges

As Question indicates 'total' ,that is, we have to find bridge length in total ( You can join Bridges to have better understanding)

Now, Walkway over hundson Bridge length= 2.063 km

Amping bridge length= 2.07 km

So, Total span of both bridges = 2.063+2.07 = 4.133 km

b) Now Leah wanna walk across and back on walkway over hudson ,that is, she wanna return to starting point from where she walk forth

So,that means, she walk double distance of length of walkway over hudson

So, total distance = 2× 2.063

= 4.126 km

Answer:

x = 56

Step-by-step explanation:

6 - 2x = 62 - 3x

-2x + 3x = 62 - 6

1x = 56

x = 56

6 - 2(56) = 62 - 3(56)

6 - 112 = 62 - 168

Answer:

54

Step-by-step explanation:

First add 7 to both sides to cancel out the -7

y/6-7(+7)=2(+7)

Then, multiply 6 to both sides to cancel the 6

y/6(6)=9(6)

y=54

Answer:

Step-by-step explanation:

sinA = sinB

  a         b

sin(117) = sin(12)

   a             12

a * sin(12) = 12 * sin(117)

a = 12 * sin(117)

         sin(12)

a = 51.4

This is an algebra expression. What we do is write it down in simplest form.

1. Write down equation

= 17 - 3 x n

= 3 x n + (-17)
