Answer:

Step-by-step explanation:

Let's just check something out before we continue to fill in the blanks.

The zeros are (x - 1) and (x -5)

y = (x - 1)(x - 5) Remove the brackets.

y = x^2 - 6x + 5 Complete the square

y = (x^2 - 6x + 9) + 5 - 9

y = (x - 3)^2 - 4

So we have a minumum at (3, - 4) Now we can go through the rest of the questions.

Part A

(1,0) and (5,0)

Part B

The vertex is (3, - 4) See the completed square above.

Part C

It's a minimum. It is the point between the two roots on the x axis. The vertex drops below the x axis.

Part D

The axis of symmetry goes through the x value of the minimum.

x = 3

The answers are all in parts A B C D. I leave you to figure out where to put them. You should be able to do that.

Guys help.. this is overdue..

loris [4]

So if his homework takes 25 minutes , and his math takes m minutes , and then as a while it takes h minutes, here’s an example of two equations you can use ;
M+25= h of 25+m=h you can do either one as you please because it doesn’t matter the order as long as they
Both equal h !! Hope this helps , sorry that it’s overdue :( have a great day:))))

What is the relationship between 9.125×10−3 and 9.125×102 ? Select from the drop-down menus to correctly complete the statement.

JulsSmile [24]

Given $9.125\times10^{-3}$ and $9.125\times10^{2}$

$9.125\times10^{2}=9.125\times10^{-3+5} \\ \\ =9.125\times10^{-3}\times10^5=9.125\times10^{-3}\times100000$

Therefore, $9.125\times10^{-3}$ is 100,000 times less than $9.125\times10^{2}$ .

Find an equation of the line. Write the equation using function notation.

Gemiola [76]

The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:

$y = -4x+9$

Step-by-step explanation:

Given equation of line is:

$4y=x-8$

We have to convert the given line in slope-intercept form to find the slope of the line

So,

Dividing both sides by 4

$\frac{4y}{4} =\frac{x-8}{4}\\y = \frac{1}{4}x-\frac{8}{4}\\y = \frac{1}{4}x-2$

Let m1 be the slope of given line

Then

$m_1 = \frac{1}{4}\\$

Let m2 be the slope of line perpendicular to given line

As we know that produt of slopes of two perpendicular lines is -1

$m_1.m_2 = -1\\\frac{1}{4} . m_2 = -1\\m_2 = -1*4\\m_2 = -4$

The slope intercept form of line is given by:

$y = m_2x+b$

Putting the value of slope

$y = -4x+b$

to find the value of b, putting (3,-3) in equation

$-3 = (-4)(3) + b\\-3 = -12 +b\\b = -3+12\\b = 9$

Putting the value of b in the equation

$y = -4x+9$

Hence,

The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:

$y = -4x+9$

Please see attached below and please explain how to solve.

Answer:

The 6% simple interest account earns more interest in 2 years.

Step-by-step explanation:

You can compare the multipliers in the interest formulas.

For simple interest, the amount in the account (A) starting with principal P and earning at rate r for t years will be ...

A = P(1 +rt)

For the values given, r=.06 and t=2, the multiplier is ...

1 +rt = 1 +.06·2 = 1.12

For interest compounded annually, the amount will be ...

A = P(1 +r)^t

For the given values, the multiplier is ...

(1+r)^t = (1.04)^2 = 1.0816

Since 1.12 > 1.0816, the account earning simple interest will earn more interest.
