Answer:
the answer is 1.3x + 2 ≥ 20
Step-by-step explanation:
the tree is already 2ft which mean it would need to be added to the rate of growth, 1.3 by the amount of year to find out the height. The question is saying however that I can be at least 20ft. so no less than 20 which is why the greater or equal to sign is used (≥)

Answer:
B
Step-by-step explanation:
3 + f = 14 [tex]\frac{2}{7}[/tex] ← change to improper fraction
3 + f = [tex]\frac{100}{7}[/tex] ( multiply through by 7 to clear the fraction )
21 + 7f = 100 ( subtract 21 from both sides )
7f = 79 ( divide both sides by 7 )
f = [tex]\frac{79}{7}[/tex] = 11 [tex]\frac{2}{7}[/tex] → B
Answer:
B. [tex]f=11\frac{2}{7}[/tex]
Step-by-step explanation:
We have the equation 3 + f = 14 2/7
We need to get f alone, doing so is subtracting three from both sides:
3 + f = 14 2/7
-3 = -3
14 2/7 - 3 = [11 2/7]
Leaving us with f = 11 2/7
This is B.
1. Mrs. Shelley's class is reading The Lion, the Witch,
and the Wardrobe. If they read 16 pages every week,
how many pages can they read in 5 weeks?
Answers
Answer:
80 weeks
Step-by-step explanation:
We can use proportions to figure out the answer to this problem:
[tex]\frac{16}{1} = \frac{x}{5}[/tex]
16 pages every week, and some amount of pages every 5 weeks. Notice that if we can multiply 1 by 5 to get 5, we should be able to multiply 16 by 5 to get the value of x. 16 times 5 is 80, and this is the answer to our problem.

(c). Under a set of controlled laboratory conditions, the size of the population P of a certain bacteria culture at time t (in seconds) is given by the function P(t)= 3t² +3e' +10, t≥0.
(1) What is the size of the population after 1 minute?
(ii) Find the average rate of change of P at t = 2 and t = 6?
(iii) How fast is the size of the population changing after 1 minute?
[Verify your answer by MATHEMATICA and attach the printout of the commands and output
Answers
(i) Since P(t) gives the population of the culture after t seconds, the population after 1 second is
P(1) = 3•1² + 3e¹ + 10 = 13 + 3e ≈ 21.155
In Mathematica, it's convenient to define a function:
P[t_] := 3t^2 + 3E^t + 10
(E is case-sensitive and must be capitalized. Alternatively, you could use Exp[t]. You can also specify that the argument t must be non-negative by entering a condition via P[t_ ;/ t >= 0], but that's not necessary.)
Then just evaluate P[1], or N[P[1]] or N <at symbol> P[1] or P[1] // N to get a numerical result.
(ii) The average rate of change of P(t) over an interval [a, b} is
(P(b) - P(a))/(b - a)
Then the ARoC between t = 2 and t = 6 is
(P(6) - P(2))/(6 - 2) ≈ 321.030
In M,
(P[6] - P[2])/(6 - 2)
and you can also include N just as before.
(iii) You want the instantaneous rate of change of P when t = 60 (since 1 minute = 60 seconds). Differentiate P :
P'(t) = 6t + 3e^t
Evaluate the derivative at t = 60 :
P'(60) = 6•60 + 3e⁶⁰ = 360 + 3e⁶⁰
The approximate value is quite large, so I'll just leave its exact value.
In M, the quickest way would be P'[60], or you can differentiate and replace (via ReplaceAll or /.) t with 60 as in D[P[t], t] /. t -> 60.
Solve the following quadratic by
completing the square.
y = x2 - 6x + 7
Answers
Answer:
x = 5 or x = 1
Step-by-step explanation:
x² - 6x + 7 = 0
x² - 6x = -7
x² - 6x + 9 = -7 + 9 1/2 of the x term than square it and add it the both sides.
(x - 3)(x - 3) = 2
( x -3)² = 2
[tex]\sqrt{(x - 3)^2[/tex] = [tex]\sqrt{2}[/tex]
(x - 3) = ± 2
x - 3 = 2 or x - 3 = -2
x = 5 or x = 1

The tangent of 62 degree is 24/7 because tan is the ratio of side opposite to the angle to side adjacent to the angle option (A) is correct.
What is trigonometry?
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a right angle triangle shown in the picture with side length.
As we know the tan is the ratio of side opposite to the angle to side adjacent to the angle.
tan62 = 24/7
Thus, the tangent of 62 degree is 24/7 because tan is the ratio of side opposite to the angle to side adjacent to the angle option (A) is correct.

Give possible values for the measures of angles A and C if ABC is a right triangle.
Answers
Answer:
0 < A < 90
0 < C < 90
Step-by-step explanation:
If B is the right angle of the triangle, then the sum of the other angles, A and C, must equate 90° since all angles in a triangle sum to 180°:
A + C = 90
A and C could both be anything between 0 and 90, but they must satisfy the equation above:
0 < A < 90
0 < C < 90

I need this TODAY or I’m so unbelievably screwed i need to know how to do these kind of table graphs really quickly i have a test tomorrow and its worth 90 percent of my grade also If you could tell me how to get slope that would make my day and night.
Thank you. And if you can tell me how to find slope that would be great.
Answers
Answer: Hey, getting slope is actually really easy!
Step-by-step explanation: So, if you’re given 2 sets of number such as (2,5) or (-7,3) then you just take them and you have to realize that 2 is x and 5 is y. also that -7 is x2 and 3 is y2. so then you use this formula (y2-y1 / x2-x1) this will give you the slope!! here’s an example using the points i said earlier: 3-5 / -7-2. so it would be 2/-9 for the slope! also i’d they only give you one point and the y intercept then you can just use the one point and then make the y intercept have a 0. so id the y intercept is 9 then the ordered pair would be (0,9) Good Luck! and let me know if you need to know how to graph the slope:)
