Write the explicit rule,
Answer:
[tex]a_{n}[/tex] = 20n + 12
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 52 - 32 = 72 - 52 = 92 - 72 = 20
This indicates the sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 32 and d = 20, thus
[tex]a_{n}[/tex] = 32 + 20(n - 1) = 32 + 20n - 20 = 20n + 12

One tool used in genetics is called a pedigree chart,are there any advantages to using this tool?The population of a city is increasing at a rate of 4% each year. In 2000, there were 236,000 people in the city. Write an exponential growth function to model this situation. Then find the population in 2009.
Answer:
A = 236,000 (1.04)^t
population in 2009 : 335,902 people
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population
r = growing rate (decimal form) = 4/100 = 0.04
t= years passed from 2000
A = population after t years
Replacing with the values given:
A = 236,000 (1+ 0.04)^t
A = 236,000 (1.04)^t
Population in 2009.
t = 2009-2000 = 9
A = 236,000 (1.04)^9
A = 335,902 people

Question 11 (Multiple Choice Worth 1 points) (05.05 MC) The length of a rectangle is shown below: On a coordinate grid from negative 6 to positive 6 on the x-axis and on the y-axis, two points A and B are shown. The point A is on ordered pair negative 2, 3, and the point B is on ordered pair 3, 3. If the area of the rectangle to be drawn is 30 square units, where should points C and D be located, if they lie vertically below A and B, to make this rectangle? C(3, −2), D(−2, −2) C(3, −3), D(−2, −3) C(−3, 3), D(−3, −2) C(−2, 3), D(−2, −2)
Answer:
C(3, −3), D(−2, −3)
Step-by-step explanation:
The given segment is 5 units long. (You can subtract the coordinates or count the grid squares to see this.)
In order for the area to be 30 square units, the product of length and width must be 30.
30 = 5×width
30/5 = width = 6
The horizontal line that is 6 units below the one shown is at y = -3. That is, the coordinates of C and D will have y-values of -3. Only one answer choice matches.
Answer:
C(3, −3), D(−2, −3)
Step-by-step explanation:

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar. Consider the given table. The “?” in the table represents the number (blank) because the average rate of change on every interval of the function is (blank).
Answer:
The answers to the blanks are:
381/3The “?” in the table represents the number 38 because the average rate of change on every interval of the function is 1/3.
Step-by-step explanation:
How you can see in the table, after the first values [x=-2, f(x)=5], each time that x add 1, f(x) add 3, (that is the reason why the average rate is 1/3), how you can see below:
2. x = 2 (were added 4 to the first number -2)
f(x) = 17 (were added 12 to the first number 5)
3. x = 5 (were added 3 to the second number 2)
f(x) = 26 (were added 9 to the second number 17)
4. x = 9 (were added 4 to the third number 5)
How in the last column were added 4, you must multiply this value by 3 (remember the average rate), so 4*3 = 12, now:
f(x) = 38 (were added 12 to the third number 26)
Blue Ray's computer sales totaled $59,500 last month. She receives a commission rate of 15% on all sales. What commission did she earn? *
Answer: $8,925
Step-by-step explanation:
Convert 15% to decimals. You can do this by dividing by 100.
[tex]\frac{15}{100}=0.15[/tex]
Now, take the total amount of the sales and multiply it by this decimal.
[tex]59,500*0.15=8925[/tex]
Solve for the variable "d" in the following equation.
[tex]F=\frac{Gm_1 m_2}{d^2}[/tex]
[tex]F = \frac{Gm_{1}m_{2} }{d^{2} }[/tex]
F x [tex]d^{2}[/tex] = G[tex]m_{1}m_{2}[/tex]
[tex]d^{2}[/tex] = [tex]\frac{Gm_{1}m_{2}}{F}[/tex]
d = ±[tex]\sqrt{\frac{Gm_{1}m_{2}}{F} }[/tex]
Since "m1" and "m2" represent different masses, we can change them to different letters. This will make it easier to solve.
m1 = m
m2 = n
F = G*m1*m2/d^2 → F = Gmn/d^2
Steps to solve for d:
F = Gmn/d^2
~Multiply d^2 to both sides
d^2 * F = d^2 * Gmn/d^2
~Simplify
d^2 * F = Gmn
~Divide F to both sides
d^2*F/F= Gmn/F
~Simplify
d^2 = Gmn/F
~Take the square root of both sides
√d^2 = ±√Gmn/F
~Simplify
d = ±√Gmn/F
Since we are done solving for d, we can input "m1" and "m2" to replace "m" and "n".
d = ±√Gmn/F → d = ±√G*m1*m2/F
Therefore, the answer is [ d = ±√G*m1*m2/F ]

Answer:
b=15
Step-by-step explanation:
360-90=270
270+60=330
360-330=30/2=15
Answer:
The measure of angle b is 15 degrees,
Step-by-step explanation:
Both triangles are isosceles. The inside one is also a right triangle. Since the big triangle is isosceles and the two angles add up to 120 degrees, they also have to be equal, meaning ∠P≅∠R=60 degrees. The inside triangle is also isosceles, meaning that m∠a=60°-b, which 60°-b representing the measure of the last angle in the smaller triangle. Since ∠a and the third angle are congruent, they each have to equal 45°. 60°-45°=15°. The measure of ∠b=15°.
Your mom is taking you shopping at the mall. She has $78 to spend on you. You already know that $18 of that money is for your school backpack. You need to get 2 shirts and 2 pairs of pants for your school uniform. The pants and the shirts cost the same amount for each. How much does each shirt or pair of pants cost?
Answer:
each coat $15
Step-by-step explanation:
$78-$18 divided by 4 =15
hope this helps :)
Answer:
The answer is that each shirt and pair of pants costs 15$
Step-by-step explanation:
So you have 78$, and you already need to buy a backpack so then you have 60$ dollars because the backpack is 18$, and 2 shirts and 2 pairs of pants is 4 pieces of clothing in all, 60$ divided by 4 pieces of clothing equals 15$ per piece of clothing (78 - 18 = 60 divided by 4 = 15)
FOR A TEST, PLEASE HELP Two angles are supplementary if their sum is 180°. The larger angle measures three degrees more than twice the measure of a smaller angle. If x represents the measure of the smaller angle and these two angles are supplementary, find the measure of each angle. The smaller angle measures ? degrees. The larger angle measures ? degrees.
Step-by-step explanation:
I think writing the given out helps a bit.
x = small angle
2x+3 = large angle <-- it's 2x since it's twice the small angle and +3 because it's 3 degrees more than the small angle.
small angle + large angle = 180
Now just substitute!
[tex]x+(2x+3)=180\\3x=177\\x=\frac{177}{3} \\x=59[/tex]
Now that you know what x equals (aka the smaller angle) now you can find the larger angle.
[tex]2(59)+3\\118+3\\121[/tex]
Answer:
The smaller angle equals 59°
The larger angle equals 121°

What is the x-intercept of f-^1(x)?
Answer:
(2 1/2, 0)
Step-by-step explanation:
In the picture attached, the complete question is shown.
f(x) = 2 1/2 - 3 1/3 * x
or
f(x) = 5/2 - (10/3)*x
f^-1(x) is the inverse of f(x), which is obtained replacing f(x) by x, and x by y, and solving for y, as follows:
x = 5/2 - (10/3)*y
(10/3)*y = 5/2 - x
y = (5/2)*(3/10) - x*(3/10)
y = (3/4) - (3/10)*x
f^-1(x) = (3/4) - (3/10)*x
at x-intercept, f^-1(x) = 0,
(3/4) - (3/10)*x = 0
(3/4) = (3/10)*x
x = (3/4)*(10/3)
x = 5/2 or 2 1/2
