Identify the polynomial written in descending order. (1 point) 9 − 14x − 7x2+ x3 x3− 7x2− 14x + 9 −7x2+ 9 + x3− 14x −14x + x3+ 9 − 7x2
Answer:
Option 2.
Step-by-step explanation:
We need to find a polynomial which is written in descending order.
Polynomial written in descending order: If the terms are written in a manner such that the powers on the variables go from highest to lowest, then it is called polynomial in descending order.
In option 1, the given polynomial is
[tex]9-14x-7x^2+x^3[/tex]
In option 2, the given polynomial is
[tex]x^3-7x^2-14x+9[/tex]
In option 3, the given polynomial is
[tex]-7x^2+9+x^3-14x[/tex]
In option 3, the given polynomial is
[tex]-14x+x^3+9-7x^2[/tex]
Only in option 2, the terms are arranged in descending order of powers.
Therefore, the correct option is 2.

A single die is rolled twice. find the probability of rolling an odd number and a number greater than 4 in either order.
The probability of rolling an odd number and a number greater than 4 in either order is 1/6.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given, a single die is rolled twice,
∴ The 36 outcomes are
(1,1),(1,2)...(1,6),(2,1)...(2,6),(3,1)...(3,6),(4,1)...(4,6)...(5,1)...(5,6)...(6,1)...(6,6).
So, N(S) = 36.
The no of favorable outcomes N(F) an odd number and a number greater than 4 in either order are [{(1,5),(1,6),(3,5)(3,6),(5,5),(5,6)} as given they can occur in either order so (1,5) and (5,1) are one combined.
∴ N(F) = 6.
So, The probability P(F) of rolling an odd number and a number greater than 4 in either order is,
P(F) = N(F)/N(S).
P(F) = 6/36.
P(F) = 1/6.

The probability of rolling an odd number and a number greater than 4 in either order when a single die is rolled twice is 1/18.
To find the probability of rolling an odd number and a number greater than 4 in either order when a single die is rolled twice, we need to first identify the possible outcomes. The odd numbers on a die are 1, 3, and 5. Since we are also looking for a number greater than 4, the only possible outcomes that meet both conditions are 5 and 6.
When the die is rolled twice, there are 6 x 6 = 36 possible outcomes. There are two favorable ways to achieve the goal: Roll a 5 (odd) first and then a 6 (greater than 4), or roll a 6 first and then a 5. Thus, there are two successful outcomes: (5, 6) and (6, 5). The probability of each individual outcome is 1/36, so the combined probability is 2/36, which simplifies to 1/18.
Therefore, the probability of rolling an odd number and a number greater than 4 in either order with a single die rolled twice is 1/18.

Which rule can be used to describe the growth of the y-values of the function y=12^x over each interval from x=-1 to x=3?
"Which rule ..." suggests you have some rules to choose from to describe the growth. Since you refer to "each interval from x=-1 to x=3", we assume your rule is concerned with more than one interval. With no further clues as to what you may be looking for, we can compute the factor by which the function grows from x=-1 to x=3.
The growth factor over that interval is the ratio of final value to initial value:
.. (12^3)/(12^-1) = 12^(3 -(-1)) = 12^4 = 20,736
Answer:
The rule "multiply by 12" describe the growth of the y-values of the function y=12^x over each interval from x=-1 to x=3.
Step-by-step explanation:
The given function is
[tex]y=12^x[/tex]
The initial value is 1 and the growth factor is 12.
It is an exponential function.
At x=-1
[tex]y=12^{-1}=\frac{1}{12}[/tex]
At x=0
[tex]y=12^{0}=12^{-1}\times 12=1[/tex]
At x=1
[tex]y=12^{1}=1 \times 12=12[/tex]
At x=2
[tex]y=12^{2}=12 \times 12=144[/tex]
At x=3
[tex]y=12^{3}=144 \times 12=1728[/tex]
Therefore the rule "multiply by 12" describe the growth of the y-values of the function y=12^x over each interval from x=-1 to x=3.

A spinner has 8 equal sectors with different letters for each sector, as shown below: a spinner with 8 equal sectors is shown. the sectors are labeled b, y, g, p, o, v, m, and r. hamlet spins the spinner 13 times, and it stops at the letter r 9 times. if he spins the spinner a 14th time, what is the theoretical probability that this time it will stop at the letter r? 1 over 14 1 over 13 1 over 9 1 over 8 question 4(multiple choice worth 1 points)
Answer:
The theoretical probability of obtaining letter 'r' at the 14th spin is:
[tex]\dfrac{1}{8}[/tex]
Step-by-step explanation:
It is given that:
A spinner has 8 equal sectors with different letters for each sector.
The sectors are labeled b, y, g, p, o, v, m, and r.
Hamlet spins the spinner 13 times, and it stops at the letter r 9 times.
We are asked to find the theoretical probability that we will get letter r at the 14th spin.
The theoretical Probability is given as the ratio of number of favorable outcomes to the total number of outcomes.
Hence, the theoretical probability of obtaining letter 'r' at the 14th spin is:
[tex]\dfrac{1}{8}[/tex]
( As there are a total of 8 outcomes( or 8 sectors) out of which there is only one sector which is red)

The Volume of the triangular prism is 124.74 cubic mm.
What is Volume?Volume is a three-dimensional quantity used to calculate a solid shape's capacity. That means that the volume of a closed form determines how much three-dimensional space it can fill. Volume is a three-dimensional quantity used to calculate the capacity of a container.
Given:
Base of the triangle (b) = 12.3 mm
Height of the triangle (h) = 8.2 mm
Length of the prism (l) = 20.5 mm
So, the volume of the triangular prism formula:
= 1/2 x b x h x l
= 1/2 x 14.4 x 2.1 x 8.25
= 7.2 x 2.1 x8.25
= 124.74 cubic mm.

Answer

Explanation
sin (x + 22)° = cos (2x - 7)°
In trigonometry for any equation where sinθ = cosΦ, θ and Φ are complementary. That is they add up to 90°
sinθ = cosΦ ⇒ θ + Φ = 90
∴ sin (x + 22)° = cos (2x - 7)°
(x + 22) + (2x - 7) = 90
x + 22 + 2x - 7 =90
3x + 15 = 90
3x = 90 - 15
3x = 75
x = 25°
