To evaluate f(1) substitute x = 1 into f(x)
f(1) = [tex](11)^{1}[/tex] = 11
The simplified solution of the function at f(1) = 11.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
The given function is,
f(x) = 11ˣ
In order to determine the value of f(1), we have to simply put x = 1 in the function,
f(1) = 11¹
As we know if the degree of any value is 1 than the solution of the expression is always the same as it was,
So,
f(1) = 11

142.3
149.9
137.8
Answer:
137.8
Step-by-step explanation:
X score for value that is greater than 45% of the data values= 156.78.
What is Standard Deviation?The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Given:
Mean= 140
Standard Deviation = 18
Now, using z- score
z= (x- B)/ A
So, Z score for value above 45 % of data set = 0.9987 - 0.0668=0.9319
0.9319 = ( x - 140)/ 18
x= 16.7742 + 140
x= 176. 4472
Hence, X score for value that is greater than 45% of the data values is 156.78.

There are ten candidates for a job. The search committee will choose three of them, and rank the chosen three from strongest to weakest. How many different outcomes are possible
Answer:
720
Step-by-step explanation:
Since we are choosing a subset of 3 people from a set of 10 people, and arranging the 3 people according to relative strength, the answer can be obtained by computing P(10,3).
P(10,3)=10! / (10-3)!
= 10!/7!
Rewrite 10 ! as
10 * 9 * 8 * 7 ! / 7!
Cancel the common factor of 7 ! and divide ( 10 * 9 * 8 ) by 1
10 * 9 * 8 = 720
Final answer:
To find the number of different outcomes possible when selecting and ranking three candidates out of ten, we calculate the permutations without repetition, using the formula 10! / (10 - 3)!, which yields 720 different outcomes.
Explanation:
The question asks for the number of different outcomes possible when a search committee must choose and rank three candidates out of ten for a job. This is a permutation problem because the order in which the candidates are ranked matters.
To calculate the number of different outcomes, we use the formula for permutations without repetition, which is n! / (n - r)!, where 'n' is the total number of items to choose from (in this case, the number of candidates) and 'r' is the number of items to choose and arrange (in this case, the number of candidates to be ranked). So, the number of different outcomes for selecting and ranking three candidates from ten is calculated as follows:
10! / (10 - 3)! = 10! / 7! = 10 × 9 × 8 = 720
Thus, there are 720 different outcomes possible when the search committee chooses and ranks three candidates out of ten.

Gordon, Caroline & Malachy share some money in the ratio
3:34.
In total, Gordon and Malachy receive £77.
How much does Caroline get? -
Answer:
£33
Step-by-step explanation:
The share ratio is 3 :3:4
So the rational division is 3 + 3 + 4 = 10
Gordon and Malachy share is £77,
[tex] calculting \: total \: amt \: shared \\ \frac{3}{10} + \frac{4}{10} = 77 \\ \frac{3 + 4}{10} = 77 \\ \frac{7}{10} = 77 \\ total \: amt \: = \frac{77 \times 10}{7} = 110[/tex]
Carol's share =
[tex] \frac{3}{10} \times 110 = 33[/tex]
=£33
Final answer:
Gordon and Malachy's combined share corresponds to 7 parts of the ratio. One part is worth £11, and since Caroline's share is 3 parts of the ratio, she receives £33 in total.
Explanation:
The question involves dividing a sum of money according to a given ratio. Since Gordon and Malachy together receive £77, we need to first find out the ratio representing the sum of their parts and then calculate Caroline’s share.
Given the ratio of Gordon, Caroline, and Malachy’s share as 3:3:4, we can see that Gordon and Malachy’s ratio adds up to 3 + 4 = 7 parts. To find the value of one part, we divide the total amount they have (£77) by 7.
£77 divided by 7 parts equals £11 per part. Since Caroline’s share is 3 parts in the ratio, Caroline receives 3 parts times £11 per part, which equals £33. Therefore, Caroline gets £33.

(If two triangles are next to each other with a straight line and one is a right angle, so is the other triangle)
Since they are both right angles, they are 3,4,5 triangles.
The 12 would count as the four since is divides by 4
The y would equal 15 because it is the longest side meaning it has to be the 5. Since we had to divide the 12 by 3 to get the four, we have to multiply the 5 by 3 to get 15.
Now to find z, you will make the equation 15/12=z/5

In a circle, if a diameter bisects a chord (that is not a diameter), then:
The chord and the diameter are perpendicular.
Suppose that chord AB is bisected by a diameter, which interserct the chord at point C.
Now, focus on triangles OAC and OBC. They have:
OA = OB because they are both radiiOC in commonAC=BC because the diameter bisects the chordSo, they are congruent. In particular, this means that angles ACO and BCO are equal. Since they sum up to 180, each of them must be 90°, so the diameter is perpendicular to the chord.
In a circle, if a diameter bisects a chord (that is not a diameter), then it must also be the perpendicular bisector of that chord.
What is a perpendicular bisector?A perpendicular bisector is defined as a line that divides an angle into two equal angles. Draw the given angle first, then cut it in half, and then draw the angle's bisector.
If a diameter bisects a chord in a circle, then it must also be the perpendicular bisector of that chord. This is because the diameter is the longest possible chord in the circle, and it passes through the center of the circle, which is the point of concurrency for all the perpendicular bisectors of chords in the circle.
Therefore, it must also be the perpendicular bisector of that chord when the diameter bisects a chord.

6x + 12x + 90 = 180
Step-by-step explanation:
Well 6x plus 12x must equal 90 degrees. 6x plus 12x plus 90 has to equal 180.
Therefore, 6x + 12x + 90 = 180

3. When we have congruent triangles, the corresponding sides are the same. Here, we know that ABC is congruent to DEC and since ED and AB are corresponding sides (my assumption), then they are equal. Set them equal:
4y + 2 = 6y - 4
2y = 6
y = 3
Plug this back into the equation for AB:
6 * 3 - 4 = 18 - 4 = 14
So, AB is 14 units.
4. Congruent triangles also have congruent corresponding angles. Here, angles ACB and DEF are congruent, while angles BAC and EDF are congruent. So, set them equal:
3y = 42
and
87 = 5x + 2
Then, y = 42/3 = 14 and x = (87 - 2)/5 = 85/5 = 13.

A weight is attached to a spring that is oscillating up and down. It takes 2 seconds for the spring to complete one cycle, and the distance from the highest to the lowest point is 5 in. What equation models the position of the weight at time t seconds?
Answer:
[tex] y=2.5 \sin(\pi t)[/tex]
Step-by-step explanation:
Time period $T$ is 2 sec.
$T=\frac{2\pi}{\omega}$
$\therefore 2=\frac{2\pi}{\omega}$
$\therefore \omega=\pi$
The amplitude is half the distance between highest and lowest points.
Thus, amplitude $A= 2.5$
The equation to the SHM is:
$y=A \sin (\omega t)$
Or,
$\boxed{y=2.5 \sin (\pi t)}$
The equation that models the position of the weight at time t seconds is y = 2.5 sin(πt).
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
We are given that;
Time taken to complete one cycle= 2sec
Distance from lowest to highest point= 5in
Now,
The position of the weight attached to a spring that is oscillating up and down can be modeled by a sinusoidal function of time. Specifically, the equation for the position (in inches) of the weight as a function of time (in seconds) can be written in the form:
y = A sin(ωt + φ) + k
where:
A is the amplitude of the oscillation, which is half the distance between the highest and lowest point. In this case, A = 5/2 = 2.5 in.
ω is the angular frequency of the oscillation, which is related to the period T (the time for one complete cycle) by the formula ω = 2π/T. In this case, T = 2 sec, so ω = 2π/2 = π rad/sec.
φ is the phase shift of the oscillation, which determines the starting position of the weight. Since no specific starting position is given in the problem, we can assume that the weight starts at the highest point, which corresponds to a phase shift of φ = 0.
In this case, k = (5 + (-5))/2 = 0.
Putting all of these values into the equation, we get:
y = 2.5 sin(πt + 0) + 0
Simplifying, we get the final equation for the position of the weight at time t seconds:
y = 2.5 sin(πt)
Therefore, by the equations the answer will be y = 2.5 sin(πt).
