What is the function?
Answer:
f(x) = x² + 6 for x < 3
and
f(x) = -x + 6 for x ≥ 3
Step-by-step explanation:
you have to break it up into two separate parts
for x less than 3 is a parabola x² where y = 6 when x = 0
f(x) = x² + 6 for x < 3
and
for x ≥ 3 the function is a line two points (3, 3) and (0, 6)
the slope m = (3 - 6) / (3 - 1) = -1
y intercept = 6 when x = 0
f(x) = -x + 6 for x ≥ 3

PEMDAS is our acronym for order of operations: Parentheses, exponents, multiplication, division, addition, subtraction.
Since we have no parentheses, we'll calculate the numbers and exponents (PEMDAS) first. "to the power of 2" is also called "squared" and means multiplying that number by itself.
(4x4) x (5x5) - (18x 18)
=16 x 25 - 324
Now we multiply: (PEMDAS)
= 400 - 324
then subtract: (PEMDAS)
=76
Answer:
76
Step-by-step explanation:
See 4^2 = 4x4 = 16
5^2 = 5x5 = 25
18^2 = 18x18 = 324
So it is
16 x 25 - 324
= 76

What is the equation of a parabola with (-3,3) as the focus, and y=5 as the directrix?
Remember no link! :)
Answer y = 1/4 (x+3)^2 + 4
Step-by-step explanation:
If the focus is (-3, 3) and the directrix is y=5, the vertex is at (-3, 4). a = 1/4p, p=1, a=1/4. (h,k) is the vertex.
y=a(x-h)^2 +k
y=1/4(x+3)^2+4

a class is planning a field trip to the aquarium. The cost of a ticket is $25.95. With the cost of transportation, each student will pay $36.00 to go on the field trip. Jay wants to know how much he will pay for transportation. Which equation will help jay find the cost of transportation,t?
Answer:
25.95 + 36
Step-by-step explanation:
You don't have any options so the answer I would say is 25.95 + 36, or the other way around.

Tell whether the following lengths are possible to be sides of a right triangle. if it is a triangle, state whether if it is a acute, right or obtuse
a. 2,2,2
b. 4,6,10
c. 7,24,25
d. 1, √3, 2
Answer:
A) an equilateral triangle with acute angles (60°)
B) isn't the lengths of a triangle
C) is a right triangle
D) is a right triangle
Step-by-step explanation:
A) 2,2,2, all sides and angles are all equal
B) applying cos rule to get the angles, an angle will be zero and a triangle can't have zero angle, thus the lengths are not that of a triangle
C) it's a right triangle as the dimensions are a pythagorean triple
D) it's a right triangle as the dimensions are a pythagorean triple

The questions on a multiple choice test have four answer choices.
Which of the following models could you use to simulate the outcome of guessing the correct answers to a 50-question test?
(HINT: Remember to choose a model with the same number of possible outcomes as each test question.)
Group of answer choices
A. flipping a coin 50 times
B. spinning a spinner with 4 equal sections 50 times
C. rolling a 6-sided die 50 times
D. spinning a spinner with 50 equal sections four times
Answer: spinning a spinner with 4 equal sections 50 times
Step-by-step explanation:
The models that one can use to simulate the outcome of guessing the correct answers to a 50-question test will be to spinn a spinner with 4 equal sections 50 times.
Flipping a coin 50 times is wrong since the coin only has two outcomes which are head and tail. Rolling a 6-sided die 50 times is also wrong.
Therefore, the correct option is B.

There are 10 counters in a bag: 3 are red, 2 are blue and 5 are green. The contents of the bag are shaken before Maxine randomly chooses one counter from the bag. What is the probability that she doesn't pick a red counter
Answer:
Step-by-step explanation: total number of counters = 10
number of red counters= 3
number of blue counters= 2
number of green counters = 5
p(of getting a red counter) =3/10
p(of not getting a red counter) = 1-3/10= 10-3/10=7/10

Yesterday, the price of a gallon of gas at five gas stations was $3.56, $3.71,
$3.62, $3.93, and $3.83, respectively, but today each gas station raised it:
price by $0.08. What is today's mean price of a gallon of gas at the five
stations?
O A. $3.81
O B. $3.65
O C. $3.89
O D. $3.73
Answer:
c
Step-by-step explanation:
The mean price of a gallon of gas at the five stations is $3.81. Therefore, option A is the correct answer.
What is mean?In statistics, the mean refers to the average of a set of values. The mean can be computed in a number of ways, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations).
Given that, Yesterday, the price of a gallon of gas at five gas stations was $3.56, $3.71, $3.62, $3.93, and $3.83, respectively.
Today each gas station raised its price by $0.08
Now, mean =(3.56+3.71+3.62+3.93+3.83+5×0.08)/5
= (18.65+0.4)/5
= 19.05/5
= $3.81
Therefore, option A is the correct answer.

Answer:
D
Step-by-step explanation:
We know that the value of x is 120, so we can substitute it into the equation they gave you.
T(x) = 0.06x + 4.5
T(x) = 0.06(120) + 4.5
Now just solve.
0.06 × 120 = 7.2
7.2 + 4.5 = 11.7
So the tax on the room is $11.70
