Choose the polynomial that is described. A trinomial in one variable of degree 3.a. 4r2-9t+7b. 3r2+4t-9 c. 4r3 d. 4r3 -9t +7
Answer:
C. 4r³
Step-by-step explanation
A trinomial is an expression having three terms. A polynomial with degree 3 that which its leading variable has a power of 3. For example an example of such polynomial in one variable is expressed as 2x³+4x²-7. This equation has 3 terms and the leading variable has a power of 3 with only x as the variable
From the given options based on the explanation, the correct answer will be 4r³. This can also be written as a trinomial as 4r³+0r²+0r
The rest contains more than one variable.
There is no trinomial.
A trinomial is a polynomial with three nonzero terms
Here we have to find trinomial in one variable of degree 3 .
Since in given four options a , b , d have equations in two variables and c have only one term so there is no trinomial.

A bucket holds 4 liters of water. If a ladle can scoop out 14 of a liter, how many scoops will it take to empty the bucket?
Step-by-step explanation:
the ladle should scoop out 56 scoops to empty the bucket because if one scoop equals 1/14, there are 14 scoops per liter, and 4 liters, so 4 times 14 equals 56
The ladle should scoop out 56 scoops to empty the bucket
What is Unit of Measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity
Given,
A bucket holds 4 liters of water.
If a ladle can scoop out 14 of a liter We need to find how many scoops will it take to empty the bucket
We know that one scoop equals 1/14 liters
1 scoop=1/14 litres
1 litre=14 scoops
As there are 4 litres
We have to multiply 14 with four to find the number of scoops to take to make the bucket empty.
14×4
56
Hence, the ladle should scoop out 56 scoops to empty the bucket

Answer:
Angle S
Step-by-step explanation:
The angle is always proportional to the opposite side. Angle opposite to the longest side has the largest angle so since Side RT is the shortest side, the angle opposite to it (or whatever the correct term is) would be Angle S.

If the point (8,-5) is 6 units above the point P(x, y) and 3 units to the right of it, then what are the coordinates of
the point P(x, y)?
Answer:
(5, -11)
Step-by-step explanation:
We know that (8, -5) is 6 units above and 3 units to the right of point P. Knowing this, let's work backwards by starting from (8,-5) and counting 6 units down and 3 units to the left on the graph.
If you counted correctly, this should place you at the (5, -11). (You can also check your work by counting 6 units up and 3 units to the right from (5, -11) and seeing if you end up at (8, -5).)

Answer:
D. It is a many-to-one functionStep-by-step explanation:
One-to-one if every y value has exactly one x value mapped onto itMany-to-one if there are y values that have more than one x value mapped onto them.We have a function that is of degree 3, so it has 3 x-intercepts which means there are points (x₁, 0), (x₂, 0), (x₃, 0), so it is a many-to-one function

3.0450 x 10^4 as an ordinary number
Answer:
30450 is the answer.
Step-by-step explanation:
Given number is [tex]3.0450 \times 10^4[/tex].
We need to write it as an ordinate number.
It is 3.0450 times 10 to the power 4.
It would mean that,
[tex]3.0450 \times 10^4=3.0450 \times 10000\\\\=\dfrac{3.0450 }{10000}\times 10000\\\\=30450[/tex]
Hence, the required answer is 30450.

5 : 6 : 9A hospital wants to survey religious participants in their city about what they seek from a hospital chaplain, so
they randomly select 5 religious meetings in the city and survey every participant in those meetings.
What type of sample is this?
Using sampling concepts, it is found that this is an example of cluster sampling.
Samples may be classified as:
Convenient: Drawn from a conveniently available pool. Random: All the options into a hat and drawn some of them. Systematic: Every kth element is taken. Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed. Stratified: Also divides the population into groups. However, only some elements of each group are surveyed.In this problem, each religious meeting is a group, and all participants are surveyed, hence, we have an example of cluster sampling.

Answer:
(5, 3 2/3)
Step-by-step explanation:
The centroid coordinates are the average of the vertex coordinates.
(A+B+C)/3 = ((2, 3) +(8, 1) +(5, 7))/3 = (2+8+5, 3+1+7)/3 = (15, 11)/3
The centroid is (5, 3 2/3).

The grocery store has 20% off from the original price on cereal. The equation for finding the sale price would be y = x - (.20x). What is the sale price if the cereal cost $3.00?
$2.20
$2.50
$2.40
$2.30
Step-by-step explanation:
y = x - 0.2x
y = 0.8x
When x = $3.00, y = (0.8)($3.00) = $2.40.
The sale price is $2.40.
Answer:
$2.40
Step-by-step explanation:
y = x - 20% of x
where x is $3.00
20% would be 1/5 of 3.00 = 3/5
3 - 3/5 = 15-3/5 = 12/5 = $2.40
