Answer:
The trees will be the same size in 12 years
Step-by-step explanation:
given the 3-foot tree can grow 1.5 feet per year
given the seeds can grow 1.75 feet per year
The trees will be the same size but it will take a while To find out how long that take we set up an equation to be
3 + 1.5x = 1.75x
3 = 0.25x
x = 12
x represents for years it take
Answer:
After 12 years both will be in same height
Step-by-step explanation:
Let 'x' be the number of years .
After 'x' years both will be in same height
Genevieve:
Rate of growth per year = 1.5 ft
Rate of growth after 'x' years = 1.5 * x = 1.5x
Height of tree after 'x' years = 3 + 1.5x
Marcus:
Rate of growth per year =1.75 ft
Rate of growth after 'x' years = 1.75 * x = 1.75x
Height of tree after 'x' years = 1.75x
After 'x' years both will be in same height
1.75x = 3 + 1.5x
1.75x - 1.5x = 3
0.25x = 3
x = [tex]\frac{3}{0.25}[/tex]
[tex]x =\frac{3*100}{0.25*100}=\frac{300}{25}[/tex]
x = 12

Which graph represents the function?
f(x)={3ifx<1xifx≥1
Answers
Answer: The graph in the bottom right corner.
Step-by-step explanation:
We have the function:
f(x) = 3 if x < 1.
f(x) = x if x ≥ 1
First, let's analyze each part of the function:
f(x) = 3 if x < 1.
We have a constant line y = 3, such that it ends at the point x = 1 with an open dot (or white dot) (because here we have the symbol <)
f(x) = x if x ≥ 1
From x = 1 and on, we have the line y = x, such that in the point x = 1 we will have a closed dot (or black dot) that means that the point does belong to the graph.
when x = 1, we have:
f(1) = 1
Then we will have the closed dot at the point (1, 1)
Then the correct option is the one in the bottom right.
Answer:
The answer is The graph on the bottom right

The average mass of an adult human is about 65 kilograms while the average mass of an ant is approximately 4×10−3 grams. The total human population in the world is approximately 6.84 billion, and it is estimated there are currently about 10,000 trillion ants alive. Based on these values, about how many times greater is the total mass of living humans compared to the total mass of all living ants? Round to the nearest whole.
Answers
Find total mass:
Human: 65 kg x 6,840,000,000 = 444,600,000,000 kg
Ants: 4x10^-3 = 0.004g
0.004 x 10,000,000,000,000,000 = 40,000,000,000,000g
Divide total grams by 1000 to get kegs:
40,000,000,000,000 /1000 = 40,000,000,000 kgs.
Divide total mass of humans by total mass of ants:
444,600,000,000 / 40,000,000,000 = 11.115
Mass of humans is 11.115 times more than ants.
Rounded to the nearest whole number = 11 times more.

In ΔXYZ, ∠Y=90° and ∠X=16°. ∠ZWY=42° and XW=260. Find the length of ZY to the nearest integer. (9th grade honors geometry)
Answers
Step-by-step explanation:
[tex] \tan(16) = \frac{y}{260 + x} \\ (260 + x) \times \tan(16) = y \\ 74.55 + 0.286x = y \\ y = 0.286x + 74.55[/tex]
[tex] \tan(42) = \frac{y}{x} \\0.9 x = y[/tex]
[tex]0.9x = 0.286x + 74.55 \\ 0.614x = 74.55 \\ x = 121.42[/tex]
[tex]y = 0.9x \\ y = 109.27 = 109[/tex]

What is Trigonometry?
Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.
What is length?
Length is a measure of distance. In the International System of Quantities, length is a quantity with dimension distance. In most systems of measurement a base unit for length is chosen, from which all other units are derived. In the International System of Units system the base unit for length is the meter.
According to question, In ΔXYZ, ∠Y=90° and ∠X=16°. ∠ZWY=42° and XW=260.
We have to find the the length of ZY.
Let the length of ZY be [tex]x[/tex] and WY be [tex]y[/tex]
From the given question and figure
[tex]tan16[/tex]°[tex]=\frac{y}{260+x}[/tex]
⇒[tex]tan16[/tex]°×[tex](260+x)=y[/tex]
⇒[tex]y=0.286x+74.55[/tex]
Now,[tex]tan42[/tex]°[tex]=\frac{y}{x}[/tex]
⇒[tex]y=0.9x[/tex]
From both the above equation,
[tex]0.9x=0.286x+74.55[/tex]
⇒[tex]x=121.42[/tex]
[tex]y=0.9x=109.27[/tex]
Hence, we can conclude that the length of ZY is [tex]109.27[/tex]

What function is the inverse of the exponential function y = 3^x?
Answers
Answer:
Step-by-step explanation:
First switch the y and x values:
[tex]x=3^y[/tex]
Take the natural log of both sides to get:
[tex]\ln(x)=y*\ln(3)[/tex]
Separate the y value:
[tex]y=\frac{\ln(x)}{\ln(3)}[/tex]
The inverse of the exponential function will be:
"y = [tex]\frac{ln(x)}{ln(3)}[/tex]".
Exponential functionAccording to the question,
The function, y = [tex]3^x[/tex]
By switching "x" and "y" of both sides of the function,
→ x = [tex]3^y[/tex]
Now,
By taking "log" both sides,
ln(x) = y × ln(3)
By separating the terms, we get
y = [tex]\frac{ln(x)}{ln(3)}[/tex]
Thus the above response is correct.
