Mathematics

Answer:

1/100(x+7)(x+3)

Step-by-step explanation:

Point: (-2 , 0.05)  X intercepts: -7 and -3

Format: y = a( x + x-intercept )( x + x-intercept )

0.05 = a( -2 + 7 )( -2 + 3 )

0.05 = a( 5 )( 1 )

0.05 = 5a

0.05/5 x 100 = 5/500 = 1/100

a = 1/100

1/100(x+7)(x+3)

PLEASE HELP WILL MARK BRAINLIEST
Deffense [45]
Compound interest
P(1+rate/100)^years
However, this questions would be easier using simple interest with calculations here.
First year — $35000x102% = $35700
Second year — $35700x102% = $36414
Third year — $36414x102% = $37142.28
Note : don’t include the dollar sign.

The area of a rectangular painting is 5/8 square yard. The width is 3/4 yard. What is the length of the painting?
vfiekz [6]

Answer:

The answer is

<h2>\frac{5}{6}  \:  \:  \:  \: yards \\</h2>

Step-by-step explanation:

Area of a rectangle = length × width

Since we are finding the length of the rectangle

length =  \frac{area}{width}  \\

From the question

area = 5/8 square yards

width = 3/4 yard

So we have

length =  \frac{5}{8}  \div  \frac{3}{4}  \\  =  \frac{5}{8}  \times  \frac{4}{3}  \\  =  \frac{5}{2}  \times  \frac{1}{3}

We have the final answer as

\frac{5}{6}  \:  \:  \:  \: yards \\

Hope this helps you
