Answer:

The 4th graph

Step-by-step explanation:

To have a maximum value, your parabola would have to open downwards. So the first 2 are wrong. Since your y-intercept is positive 4, your graph would have to touch the y axis at 4. The 3rd graph is wrong since it touches the y-axis at a negative point. The correct answer would be the 4th answer choice.

Which is an arithmetic sequence?

B) is an arithmetic sequence because you are adding by 2 each time. The other sequences don’t match this criteria.
I’m sorry I’m not sure what else to say I hope this somewhat helped :/
Have a great day :)

Answer:

(x+1)(x+2)

Step-by-step explanation:

x^2 + 3x + 2

find what multiples to 2 and adds to 3

Factors of 2 are 1 and 2, 2 + 1 = 3.

so the binomial would be (x+1)(x+2)

and then you would need to do FOIL to check

First: x * x = x^2

Outer: x * 2 = 2x

Inner: x * 1 = x

Last: 1 * 2 = 2

Then simplify: x^2 + 2x + x + 2

x^2 + 3x + 2

Answer:

9/49

Step-by-step explanation:

The probability of landing on an even number is 3/7.

Because there are only 3 numbers even out of 7 total numbers.

$3/7 \times 3/7$

$= 9/49$

there are 13 porters carrying total weight of 195 kg on an expeditioin. extra porters joined the group so, they carry average we

Answer: 2 porters joined the group

Step-by-step explanation:

First, you are told that "13 porters are carrying a total weight of 195kg". You can use this information to create an equation to find the average weight carried by each porter.

$\frac{195 kg}{13}=15kg$

^195kg (total weight) divided by 13 (the number of porters) is equal to 15kg (the average weight carried by each of the 13 porters).

You are then told that "extra porters join the group, so they carry an average weight of 13 kg of baggage". because some porters joined the group, you'll have to add p (p = number of porters) to the original equation and change the average weight from 15kg to 13kg.

$\frac{195kg}{13 +p} = 13kg$

^195kg (total weight) divided by 13+p (total number of porters after some joined group) is equal to 13kg (new average weight)

You can then use your new equation to solve for "p" and find the number of porters added.

p = 2
