Express the product of 2x^2+7 and 5+ x in standard form

Answer:

Step-by-step explanation:

boat was at 43.2 m/s   speed increase to 144 m/s

if the boat was moving 0 m/s and increased to 144 m/s - 43.2 m/s accelerating at 25.2 m/s²,  it would take the same amount of time

25.2 m/s² × x seconds = (144 - 43.2) m/s      solve for x in seconds

x seconds = 100.8 m/s   /  25.2 m/s²

x seconds = 4 (m/s /ms²)  = 4 (m/s × s²/m)  = 4 seconds   the  units match

x = 4 seconds

Answer:

D

Step-by-step explanation:

you need to divide by 2. And you need to simplify a fraction.

Answer:

y - 2x = 3

Step-by-step explanation:

Use the point-slope formula y - k = m(x - h), with h = 0, k = 3 and m = 2:

y - 3 = 2(x - 0), or

y - 3 = 2x, or

y - 2x = 3

Note that the given point, (0, 3), is the y-intercept of this line, and so we immediately know b in y = mx + b:  it is 3.

Answer:

C.) $1,625

Step-by-step explanation:

Going by the numbers on the graph, you can immediately tell $1,350 and $1,475 are way too low, so cancel those out and you get $1,625 and $1,800

From here, you can see that in 5 years it hasn't gone up by far, so it won't be 1,800$ by 10 years end, making the answer clear

You can just double 280 and get 560, which the closest answer is 1,625

It's really just a high-low estimate question, 2 answers are too high or low, one is close but not really, and one is just right- or inbetween

$1,625

The amount $1625 is closest to the value of the investment 10 years after the initial investment option third is correct.

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]

where a is a constant and a>1

Let's suppose the exponential function that model the problem is:

 [tex]\rm y = ae^k^x[/tex]

Plug x = 1 and y = 1050

[tex]\rm 1050 = ae^k[/tex] ...(1)

Plug x = 2 and y = 1103

[tex]\rm 1103 = ae^2^k[/tex]  ...(2)

Divide equation (2) with (1)

[tex]\rm e^k = 1.0504[/tex]

Taking ln to get the value of k

k = 0.0491

a = 999.69

The exponential function:

[tex]\rm y = (999.6902)e^{0.0491}^x[/tex]

Plug x = 10 years in the above function:

y = $1633.44

Which is close to $1625

Thus, the amount $1625 is closest to the value of the investment 10 years after the initial investment option third is correct.

Answer:

42√3

Step-by-step explanation:

4√27 = 4√(9)(3) = 12√3

6√75 = 6√(25)(3) = 30√3

12√3 + 30√3 = 42√3

Step-by-step explanation:

Answer:

y = 2x + 8

Step-by-step explanation:

To find the line, use the equation y = mx + b.

Plug in the slope and given point, then solve for b:

y = mx + b

2 = 2(-3) + b

2 = -6 + b

8 = b

Plug in the slope and b into the equation:

y = 2x + 8

So, the equation of the line is y = 2x + 8

Answer:

m

Step-by-step explanation:

Answer:

5.56 m

Step-by-step explanation:

Circumference = 2πr

r is the radius, however the diameter is given. The radius is half the diameter. So the radius is:

1.8 ÷ 2 = 0.9

Circumference = 2 × π × 0.9

= 5.56 m ( in 3 significant figures )

Answer: 2/7

Step-by-step explanation:

There are 7 letters in January, and 2 "a"s in order to find the probability, simply take 2/7. You can either leave it in the fraction form, or use the calculator, showing you have a 0.2857% chance of picking an "a"

2/7

there are 7 letters in jAnuAry and as you can see there are 2 A's so there is a 2/7 chance which is higher of a chance than the rest of the letters which are 1/7 each so it is most likely you would draw A although I can't fully say that because there is a 5/7 chance of drawing the other letters. Another way to say it is there is a 0.28571428571% chance of drawing A but there is a 0.71428571428% chance of drawing any other letter.

Answer:

We have the value as;

8x/5

Step-by-step explanation:

Here, we want to get the breakdown of the given expression

We have (x^2 - 9) as (x-3)(x + 3)

So we have;

2x/(x + 3) * (x-3)(x+3)/5 * 4/(x-3)

= 2x * 4/5= 8x/5
