Find the 22nd term of the sequence described by the
explicit formula:
f(n) = 8 + 3(n - 1)
[tex]\boxed{\boxed{\pink{\bf \leadsto The \ 22nd \ term \ is \ 71. }}}[/tex]
Step-by-step explanation:Given that the nth term of the Arthemetic Sequence is given by :-
[tex]\implies f(n) = 8 + 3(n-1) [/tex]
And we need to find the 22nd term .
So in place of n substitute 22 .
[tex]\bf\implies f(n) = 8 + 3(n-1) \\\\\bf\implies f_{22} = 8 + 3(22-1) \\\\\bf\implies f_{22} = 8 + 3\times 21 \\\\\bf\implies f_{22} = 8 + 63 \\\\\bf\boxed{\bf\implies f_{22} = 71 }[/tex]
Hence the 22nd term is 71 .Which integer makes the sentence true? (a) -7 (b) 7 (c) 17 (d) -17

natalie went skydiving, she jumped out of the plane at 3,080 feet above the ground. at 1,710 feet above the ground her parachute deployed, and instead of continuing to fall, she rose 35 feet. at this point, how far is she from the plane?
Answer: 1675 feet
Step-by-step explanation: Starting at 3080 feet she falls 1710. We subtract 1710 from 3080 and get her position at 1370 feet above the ground. She then rises 35 feet. 1370+35 = 1405 feet above the ground.
We know that the plane is 3080 feet above the ground, and that Natalie is only 1405 feet above the ground. We just have to find the difference in their positions in order to find out how far she actually is from the plane. 3080-1405 = 1675 feet
2x - y + 3z = -6
-x + 2y - 3z = 12
y + 5z = -6
Answer:
Solving the system of equations we get:
x=2, y=4, z=-2
Step-by-step explanation:
We need to solve the system of equations
[tex]2x - y + 3z = -6\\-x + 2y - 3z = 12\\y + 5z = -6[/tex]
Let:
[tex]2x - y + 3z = -6--eq(1)\\-x + 2y - 3z = 12--eq(2)\\y + 5z = -6--eq(3)[/tex]
First we find value of y from equation 3
[tex]y+5z=-6\\y=-6-5z[/tex]
Put value of y in equation 1
[tex]2x - y + 3z = -6\\2x-(-6-5z)+3z=-6\\2x+6+5z+3z=-6\\2x+8z=-6-6\\2x+8z=-12---eq(4)[/tex]
Now, put value of y in equation 2
[tex]-x + 2y - 3z = 12\\-x+2(-6-5z)-3z=12\\-x-12-10z-3z=12\\-x-13z=12+12\\-x-13z=24--eq(5)[/tex]
Multiply equation 5 with 2 and add both equations 4 and 5
[tex]2x+8z=-12\\-2x-26z=48\\--------\\-18z=36\\z=\frac{36}{-18}\\z=-2[/tex]
So, we get z=-2
Now put value of z in equation 3
[tex]y+5z=-6\\y+5(-2)=-6\\y-10=-6\\y=-6+10\\y=4[/tex]
So, we get y=4
Now, put value of y=4, and z=-2 in equation 1
[tex]2x-y+3z=-6\\2x-4+3(-2)=-6\\2x-4-6=-6\\2x-10=-6\\2x=-6+10\\2x=4\\x=\frac{4}{2}\\x=2[/tex]
So, solving the system of equations we get:
x=2, y=4, z=-2

Find the length of AB
Answer:
AB is 15
Step-by-step explanation:
AB and BC are equal because the line that goes through the triangle is going through at a 90 degree angle, u can see that by the small square, and u know it's in the middle bc of the short lines on AD and DC, the short lines means that they are congruent, so:
5x = 4x + 3
subtract 4x from both sides
x = 3
Now u have x, put it in the equation
5x = 5(3) = 15
Alyssa had 45$ to spend on 6 snacks.after buying them she had 12$ left how much did each snack cost?
Each snack cost $5.50
You start with $45, and afterwards end up with $12, so subtract 12 from 45 and you end up with 33. Then divide 33 by 6, since she bought 6 snacks, and you get $5.50.
you have 15 milk chocolate Valentines and 10 dark chocolate Valentine.What is the probability that the first Valentine handed out is milk chocolate and the second is dark chocolate.
Answer:
15/25 cuz 25 is the total and there's 15 milk. 2nd as dark chocolate would then be 10/24 cuz you've already taken one chocolate. Multiply by both would be 3/5 × 5/12 = 1/4. Percentage would then be 1/4 = 0.25 , and multiply that by 100% would then be 25%
Answer:
probability of getting milk chocolate =3/5
while
the probability of getting dark chocolate is 2/5
Step-by-step explanation:
milk chocolate=15
dark chocolate=10
there fore total=25
probability of getting milk chocolate=15/25. =3/5
while
the probability of getting dark chocolate=10/25=2/5

Find the equation of the line tangent to the graph of
y = sin^-1 (x/5) at x = 5/2. Show your work.
Answer:
[tex]\displaystyle y=\frac{2\sqrt{3}}{15}x+\frac{\pi-2\sqrt{3}}{6}[/tex]
Step-by-step explanation:
We want to find the equation of the line tangent to the graph of:
[tex]\displaystyle y=\sin^{-1}\left(\frac{x}{5}\right)\text{ at } x=\frac{5}{2}[/tex]
So, we will find the derivative of our equation first. Applying the chain rule, we acquire that:
[tex]\displaystyle y^\prime=\frac{1}{\sqrt{1-\left(\dfrac{x}{5}\right)^2}}\cdot\frac{1}{5}[/tex]
Simplify:
[tex]\displaystyle y^\prime=\frac{1}{5\sqrt{1-\dfrac{x^2}{25}}}[/tex]
We can factor out the denominator within the square root:
[tex]\displaystyle y^\prime =\frac{1}{5\sqrt{\dfrac{1}{25}\big(25-x^2)}}[/tex]
Simplify:
[tex]\displaystyle y^\prime=\frac{1}{\sqrt{25-x^2}}[/tex]
So, we can find the slope of the tangent line at x = 5/2. By substitution:
[tex]\displaystyle y^\prime=\frac{1}{\sqrt{25-(5/2)^2}}[/tex]
Evaluate:
[tex]\displaystyle y^\prime=\frac{1}{\sqrt{75/4}}=\frac{1}{\dfrac{5\sqrt{3}}{2}}=\frac{2\sqrt{3}}{15}[/tex]
We will also need the point at x = 5/2. Using our original equation, we acquire that:
[tex]\displaystyle y=\sin^{-1}\left(\frac{1}{2}\right)=\frac{\pi}{6}[/tex]
So, the point is (5/2, π/6).
Finally, by using the point-slope form, we can write:
[tex]\displaystyle y-\frac{\pi}{6}=\frac{2\sqrt{3}}{15}\left(x-\frac{5}{2}\right)[/tex]
Distribute:
[tex]\displaystyle y-\frac{\pi}{6}=\frac{2\sqrt{3}}{15}x+\frac{-\sqrt{3}}{3}[/tex]
Isolate. Hence, our equation is:
[tex]\displaystyle y=\frac{2\sqrt{3}}{15}x+\frac{\pi-2\sqrt{3}}{6}[/tex]

5 0.10
6 0.05
2. P(x = 4) = _________
3. P(x ≥5) = __________
4. On average, how long would you expect a new hire to stay with the company?
Answer:
2.) 0.10 (3.) 0.10 (4.) 2.43
Step-by-step explanation:
Given that:
x p(x)
0 0.12
1 0.18
2 0.30
3 0.15
4
5 0.10
6 0.05
X : __0__ 1 ___ 2 ___ 3 _____ 4 ____ 5 ____ 6
p(x):0.12_0.18_0.30_0.15__0.10___0.10 ___0.05
Σ of p(x) = 1
(0.12 + 0.18 + 0.30 + 0.15 + x + 0.10 + 0.05) = 1
0.9 + x = 1
x = 1 - 0.9
x = 0.1
2.)
P(x = 4) = 0.10
3.)
P(x = 5) = 0.10
4.)
Σ(x * p(x)) :
(0*0.12) + (1*0.18) + (2*0.3) + (3*0.15) + (4*0.1) + (5*0.1) + (6*0.05) = 2.43
Jessica is selling books during the summer to earn money for college. She
earns a commission on each sale but has to pay for her own expenses.
After a month of driving from neighborhood to neighborhood and walking
door-to-door, she figures out that her weekly earnings are approximately a
linear function of the number of doors she knocks on.
She writes the equation of the function like this: E() = 10x- 35, where xis the
number of doors she knocks on during the week and E(x) is her earnings for
the week in dollars.
What does the slope of Jessica's function represent?
Answer:
A you can check it by substituting values into x like 5 and 6 then compare the E(X) value
The solution is :
The slope represents the rate of change of earnings in a week for every unitary change in number of doors knocked. For Jessica's function, her earnings change by +7 units for every unit of door she knocks.
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
The slope of any linear function tells us the rate of increase in Y given 1 unit increase in X
[note the equation as y = mx+b ].
Here, m is the slope.
Jessica's weekly earning function is:
E(x) = 7x - 25
Where,
E(x) is her weekly earnings
x is the number of doors she knocks
So, when comparing this to the meaning of slope stated above, we can say that the slope of Jessica's function represents the rate of change of earnings in a week for every unitary change in number of doors knocked.

Step-by-step explanation:
Remember the identity sin²x + cos²x = 1.
Therefore 1 - cos²x = sin²x and 1 - sin²x = cos²x.
sqrt(1 - cos²x) / sinx + sqrt(1 - sin²x) / cosx
= sqrt(sin²x) / sinx + sqrt(cos²x) / cosx
= sinx / sinx + cosx / cosx

Find the equation of the line through point (−1,2) and perpendicular to x+3y=3.
Answer:
-2x
Step-by-step explanation:
As you can see the line is perpendicular the the given equation and passes through the point (-1,2).
Answer:
y=3x+5
Step-by-step explanation:
the equation x+3y=3 is in standard form (ax+by=c)
we can put it into slope intercept form (y=mx+b) to make it easier.
subtract x from both sides
3y=-x+3
divide by 3
y=-1/3x+1
Perpendicular lines have slopes that are opposite (one is negative and one is positive) and reciprocal, so if you mutiply them together, it will equal -1
use this equation:
-1/3m=-1
multiply by -3 on both sides
m=3
equation so far: y=3x+b (b is a placeholder)
since the equation passes through the point (-1,2), we can substitute it into the equation
2=3(-1)+b
2=-3+b
5=b
the equation is y=3x+5
Hope this helps!

Answer:

Step-by-step explanation:
Given the expression
g(x) = 2x and h(x) = x^2 + 4
Find hoh(-4)
First we need to find (hoh)(x)
(hoh)(x) = h(h(x))
h(h(x)) = h(x^2+4)
h(x^2+4) = (x^2+4)²+4
h(x^2+4) = x⁴+8x²+16 + 4
h(x^2+4) = x⁴+8x²+20
h(h(x)) = x⁴+8x²+20
when x = -4
h(h(-4)) = (-4)⁴+8(-4)²+20
h(h(-4)) = 256+128+20
h(h(-4)) = 404
Hence hoh(-4) is 404
