A tree initially measured 18 feet tall. Over the next 3 1/2 years
Answers
Answer:
5 ft/yr
Step-by-step explanation:
This is the whole question: A tree initially measured 18 ft tall. Over the next 3 1/2 years, it grew to a final height of 35 1/2 feet. During those 3 1 /2 years, what was the average yearly growth rate of the height of the tree?
The tree grew 35.5 - 18 ft = 17.5 feet in 3.5 years
This average leads to 17.5 ft / 3.5 yr = 5 ft/yr
The question is incomplete, the complete question is;
A tree measured 18 feet tall. Over the next 3 1/2 years, it grew to final height of 35 1/2 feet. During those 3 1/2 years, what was the average yearly growth rate of the height of the tree?
Answer:
5 feet per year
Step-by-step explanation:
Given that the initial height of the tree = 18 feet
Final height of the tree = 35.5 feet
Time interval = 3.5 years
Now;
Increase in length of tree = Final height of the tree - initial height of the tree
Increase in length of tree = 35.5 - 18 = 17.5 feet
Rate of growth of tree = increase in height of tree/ time taken
Rate of growth of tree = 17.5 feet/ 3.5 years
Rate of growth of tree = 5 feet per year

Consider these functions:
For x ≥ 0, the value of f(g(x)) is __
For x ≥ 0, the value of g(f(x)) is __
For x ≥ 0, functions f and g __ inverse functions
Answers
Answer:
Because f(g(x)) = g(f(x)) = x, f and g are inverse functions.
Step-by-step explanation:
f(g(x)) = f([tex]\frac{1}{4}\sqrt{x}[/tex]) = [tex]16(\frac{1}{4}\sqrt{x} ) ^{2} = 16(\frac{1}{16}x)=x[/tex]
g(f(x)) = g [tex](16x^{2}) = \frac{1}{4}\sqrt{16x^{2} } = \frac{1}{4}(4x) = x[/tex]

Given the sequence, 26, 13, 6.5, ..... find a) the 10th term and b) the sum of the first 18 terms X Clear * Undo Redo
Answers
Answer:
[tex]T_{10} = 0.05078125[/tex]
[tex]S_{18} = 51.9998016358[/tex]
Step-by-step explanation:
Given:
Sequence = 26, 13, 6.5 ....
Solving (a): The 10th term
The sequence is a geometric progression and the nth term will be solved using:
[tex]T_n = ar^{n-1}[/tex]
In this case:
[tex]n = 10[/tex]
[tex]r = \frac{T_2}{T_1}[/tex] --- Common Ratio
[tex]r = \frac{13}{26}[/tex]
[tex]r = 0.5[/tex]
[tex]a = 26[/tex] --- First term
So, [tex]T_n = ar^{n-1}[/tex] becomes
[tex]T_{10} = 26 * 0.5^{10-1}[/tex]
[tex]T_{10} = 26 * 0.5^{9}[/tex]
[tex]T_{10} = 26 * 0.001953125[/tex]
[tex]T_{10} = 0.05078125[/tex]
Solving (b): The sum of first 18 terms
This will be calculated using:
[tex]S_n = \frac{a(1 - r^n)}{1 - r}[/tex]
Substitute values for n, a and r
[tex]S_{18} = \frac{26 * (1 - 0.5^{18})}{1 - 0.5}[/tex]
[tex]S_{18} = \frac{25.9999008179}{0.5}[/tex]
[tex]S_{18} = 51.9998016358[/tex]
Hence, the sum of first 18 terms is 51.9998016358

si sna es 12 años menor que eva y dentro de 7 años la edad de eva es el doble que la edad de ana que edad tiene eva
Answers
Responder:
17
Explicación paso a paso:
Dejar ;
Edad de Eva = x
Edad de Ana = x - 12
Dentro de los 7 años de la edad de Eva, la edad de Ana será el doble
x + 7 = 2 (x - 12 + 7)
x + 7 = 2 (x - 5)
x + 7 = 2x - 10
x - 2x = - 10 - 7
-x = - 17
x = 17
Por lo tanto, Eva tiene 17 años.

Angles A and B are complementary. Angle A measures 3x + 10
degrees and angle B measures 2x + 20 degrees. What is the value of
x?
Answers
Answer:
x = 12
Step-by-step explanation:
Lets set up the equation!
Complementary angles equal 90 degrees.
2x + 20 + 3x + 10 = 90
Now lets combine the like terms!
2x + 3x 20+ 10
5x +30 = 90
Now subtract 30 from both sides!
5x = 60
Divide each side by 5
x = 12
