Stells [14]

Based on the calculation below, the balance on Neela's statement is $153.

Balance on statement = Actual amount in the account - Monthly fee - Overdraft protection fee - Check written + Amount transferred ............ (1)

Substituting all the relevant values into equation (1), we have:

Balance on statement = $256 - $8 - $33 - $312 + $250

Balance on statement = $153

3. f(-6) = 12+1 =13

f(-2) = 4+1 = 5

f(0) =1

Range {1,5,13}

4. f(-2) = (-2)^3+1 =-7

f(-1) = (-1)^2 +1 =0

f(3) = (3)^3 +1 = 28

Range = {-7,0,28}

5.the sequence is arithmetic

d= -11+19 = 8

an = a1 + d(n-1)

an = -19 +8(n-1)

6.l =w+5

a =l*w

a(w) =(w+5) * w

a(w)= w^2 +5w

f(w) = w^2 +5w

f(8) = 8^2 +5(8)

f(8) = 64 +40

f(8) =104 in^2

I need help ASAP!! Please explain how to do solve the problem.

olga55 [171]

Answer:

Step-by-step explanation:

The co-ordinates of the smaller and larger triangles are 4,5 3,2 & 6,3 and 12,15 9,6 18,9

To find out dilation factor,

Co-ordinates of smaller triangles* dilation factor=co-ordinates of

larger triangles(or use (kx,ky) where k is the dilation factor and x and y are the co-ordinates)

(4,5) (3,2) (6,3)k=(12,15) (9,6) (18,9)

Equate and solve,

k=(12,15) (9,6) (18,9)/(4,5) (3,2) (6,3)[Informal]

k=3

Sammy bought shoes that cost

lara [203]

Before sales tax he would have to pay $40 * (1 - 0.25) + $100 * (1 - 0.35) = $30 + $65 = $95.

With a 6% sales tax he'd have to pay 1.06 * $95 = $100.70.

i hope this helps! :D

Carlo is building a wooden box that is shaped like a cube. He wants the box to have a volume of 64 cubic inches.What is the area

atroni [7]

<h3>Answer: 16 square inches</h3>

Explanation:

Apply the cube root to 64 to get $\sqrt[3]{64} = 64^{1/3} = 4$

The exponent 1/3 is handy if your calculator doesn't have a cube root button.

This wooden cube has side lengths of 4 inches each.

Each square face will have an area of 4^2 = 4*4 = 16 square inches.
