y = 82 ( 1.045 ) x

What is the rate of growth Michael expects each week after launching the website?

A. 104.5%
B. 95.5%
C. 4.5%
D. 0.045%

Answers

Answer:

Michael starts a website for people in his town to share news and photos. Before launching the website, he has his friends and family sign up. Then, he uses the equation shown below to estimate the number of user, y, who will have signed up x weeks after he officially launches the website.

y = 82(1.045)x

What is the rate of growth Michael expects each week after launching the website?

The answer will be %0.045

Step-by-step explanation:

The rate of growth Michael expects each week after launching the website is 4.5%.

Given that,

The function is y = 82 (1.045)x.We need to find the rate of growth.

Based on the above information, the calculation is as follows:

Since 1.045 is given so this means 4.5% is the growth rate.

Therefore we can conclude that the rate of growth Michael expects each week after launching the website is 4.5%.

Show that the two triangles given beside are similar and calculate the lengths of sides PQ and PR.

Answers

9514 1404 393

Answer:

ΔABC ~ ΔPQRPQ = 8PR = 14

Step-by-step explanation:

Angles A and P are marked congruent; angles B and Q are marked congruent, so the triangles are similar by the AA similarity postulate. The similarity statement can be written ...

ΔABC ~ ΔPQR by AA similarity

The ratio of sides of PQR to ABC is the ratio QR/BC = 12/6 = 2. That is, each side in the larger triangle is 2 times the length of the corresponding smaller side.

PQ = 2·AB = 2·4 = 8

PR = 2·AC = 2·7 = 14

The side lengths of interest are ...

PQ = 8, PR = 14

Write an equation of the line that passes through the given point and has the given slope.
(4, 3); slope 1/2

Answers

Answer:

y = 1/2x + 1

Step-by-step explanation:

m = 1/2

Slope-intercept:

y - y1 = m(x - x1)

y - 3 = 1/2(x - 4)

y - 3 = 1/2x - 2

y = 1/2x + 1

Write the equation in slope-intercept form: 2x + y =3
y= 2x + 3
y= -2x -2
y= -2x + 3
y= 2x-3

Answers

it is y=-2x+3 because once you take the 2x to the other side it becomes negative.

Which is the equation of a line with a slope of -1 and a y-intercept of -6?
A y = -6x - 1
B y = -x - 6
C y = x - 5
D y = x + 6

Answers

I say A, because of it both being negative & having a y intercept .

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 1 and c = - 6 , then

y = - x - 6 → B

Diego's family car holds 14 gallons of fuel. Each day the car uses 0.6 gallons of fuel. A warning light comes on when remaining fuel is 1.5 gallons or less.

Answers

Answer:

capacity of car = 14 gallons

consumption of fuel in one day = 0.6 gallons

consumption of fuel in 14 days = 14 x 0.6 = 8.4 gallons

fuel remaining in car = 14 - 8.4 = 5.6 gallons

so they can drive the car without warning.

consumption of fuel in one day = 0.6 gallons

consumption of fuel in 25 days = 25 x 0.6 = 15 gallons

fuel remaining in car = 14 - 15 = -1 gallons

so they can't drive the car without warning.

the expression 14 - 0.6t represents remaining fuel in the vehicle, where t represents number of days.

14 - 0.6t = 1.5

or - 0.6t = 1.5 - 14 = - 12.5

or t = -12.5 / - 0.6

or t = 20.8333 days

so he can drive 20 days without warning. E.

14 - 0.6t < 1.5

or t < 20.8333

here t represents number of days car can drive without warning light.

Step-by-step explanation:

The inequality is

The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days

14 gallons-1.5 gallons=12.5 gallons

we know that

If the remaining fuel is greater than 1.5 gallons Diego's father can drive the car without the warning light coming on

Let

x ----> the number of days

----> inequality that represent the situation

Solve for x

The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days

hi i would rly appreciate ur help on this. I need to write these expressions as products:
1. ((a+1)^3)+(x^3)
2. ((y-2)^3)-27
3.((a-b)^3)+b^3
4. (8x^3)+((x-y)^3)
5. (27a^3)-((a-b)^3)
Thank you so much i rly appreciate it

Answers

Answer:

1.) ((a+1)^3)+(x^3) = a^3 + 3a^2 + 3a + x^3 + 1

2.) ((y-2)^3)-27 = (y^2-y + 7) x ( y - 5 )

3.) ((a-b)^3)+b^3 = a (a^2 - 3ab + 3b^2 )

4.) (8x^3)+((x-y)^3) = 9x^3 -3x^2 y + 3xy^2 - y^3

5.) (27a^3)-((a-b)^3) = 26a^3 + 3a^2 b - 3ab^2 + b^3

5) factor = (a+b)(a+b)^ 2 if a is squared and if b is cubed and moved over to = 0 then we can find (a+b)(a+b)^2 but in all cases of quadratics you can set (x -1 ) = 1 and (x-1 ) = 1 so they are always positive. Which is the same if they start of negative.

For question 5 we have a factor solved (a+b)(a+b)^ 2

Which means the same as this expansion
