PLEASEEEEEEEEEEEEEEEEEEEE HELP MEE YALL WITH ALL 4 QUESITONS

Mathematics
1 answer:
ValentinkaMS [17]2 years ago
6 0

Answer:

Step-by-step explanation:

17. Domain is all real numbers because the equation has a y-value for all x-values as far as we can see with the information given.

18. Range is 3< y <8, because the equation only has values for x where y is between those numbers.

19. Range is 3> y >-∞ (negative infinity) because the parabola's vertex has a y-coordinate of 3 and the parabola goes on forever in the negative direction (as seen by the arrows).

20. Domain is -∞ < x < 4 because the parabola's vertex has an x-coordinate of 4 and goes on forever in the negative x direction.

Hope this helps! :)

This table shows values represented by an exponential function.
Bad White [126]

Answer:

a = 2 , f(2)=9

b = 4 , f(4)=64

And replacing the data into the average rate formula we got:

m = \frac{64-9}{4-2}= 27.5

And then the best answer for this case would be:

C. 27.5

Step-by-step explanation:

For this cae we know that the average rate of change of a function is given by this general expresion:

m = \frac{f(b) -f(a)}{b-a}

For this special case from the info of the table we have:

a = 2 , f(2)=9

b = 4 , f(4)=64

And replacing the data into the average rate formula we got:

m = \frac{64-9}{4-2}= 27.5

And then the best answer for this case would be:

C. 27.5

The sum of three times a number and seven is greater than twice the number minus four
swat32
I'm guessing you want this written as an equation, so here it is.
3n+7>2(n-4)
These can be really tricky at times, so I suggest looking for "clues" in the wording, such as add, subtract, and other things. Also look for what numbers are "paired" together, like in parentheses. Hope that this helps!

Anya buys some avocados that cost $1.50 each. What is the total cost of her
Aneli [31]
Answer C
Because it says $1.50 EACH so to get the answer you’ll need to multiply $1.50 with each avocado she buys to get the total cost

you bought your friends a heart shaped pound of chocolate caramels. You anticipate each chocolate was 50 calories. Each chocolat
Wittaler [7]

There was 25.37% error in calculations.

Step-by-step explanation:

Given,

Anticipated calories = Approx value = 50 calories

Actual calories = Exact value = 67 calories

Percent error = \frac{|aprrox\ value-exact\ value|}{exact\ value}*100

Percent error = \frac{|50-67|}{67}*100

Percent error = \frac{|-17|}{67}*100=\frac{17}{67}*100

Percent error = \frac{1700}{67}

Percent error = 25.37%

There was 25.37% error in calculations.
