Answer:
Approx. 12.124 units tall
Step-by-step explanation:
Since you need to find the height (which is adjacent to the given angle), you need to use cosine (adj. over hypotenuse).
cos(30) = x/14
Multiply both sides by 14:
14cos(30) = x
Hope this helps :)
Since in this triangle the side opposite of the 90 degree angle is 14, we know the side opposite the 30 degree angle is 14/2 = 7
Then, we multiply 7 by sqrt(3) and get 7sqrt(3) as the side opposite the 60 degree angle.

Given:
The number of alligators in a wildlife is given by the function
[tex]f(x)=3450(1.04)^{x+1}[/tex]
To find:
The average growth rate of change from the 4th year to the 7th year.
Solution:
We have,
[tex]f(x)=3450(1.04)^{x+1}[/tex]
For x=4, we get
[tex]f(4)=3450(1.04)^{4+1}[/tex]
[tex]f(4)=3450(1.04)^{5}[/tex]
[tex]f(4)=4197.4525[/tex]
For x=7, we get
[tex]f(7)=3450(1.04)^{7+1}[/tex]
[tex]f(7)=3450(1.04)^{8}[/tex]
[tex]f(7)=4721.5632[/tex]
Now, the average growth rate of change from the 4th year to the 7th year is
[tex]m=\dfrac{f(7)-f(4)}{7-4}[/tex]
[tex]m=\dfrac{4721.5632-4197.4525}{3}[/tex]
[tex]m=\dfrac{524.1107}{3}[/tex]
[tex]m\approx 174.70[/tex]
Therefore, the average growth rate of the change from the 4th year to the 7th year is 174.70 per year.

2x+3+x2 if x=4 is 27
Step-by-step explanation:
2*x or 2*4=8
8+3=11;
and x or 4 times itself is 16
so we add it all together and get 27.
Have a great day!
Answer:
27
Step-by-step explanation:
Not sure if you mean x to the power of 2, so I'll assume that.
Replacing the variable for 4 should look like:
2(4) + 3 + 4^2
8 + 3 + 16 (4 to the power of 2 is equivalent to 4 x 4 which is 16)
Now add them all, 27.
determine the simple interest when:
principal is $890, interest rate is 4.25% and the time is over 2 years
Answers
Answer:
$75.65
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.25%/100 = 0.0425 per year,
then, solving our equation
I = 890 × 0.0425 × 2 = 75.65
I = $ 75.65
The simple interest accumulated
on a principal of $ 890.00
at a rate of 4.25% per year
for 2 years is $ 75.65.
What is 3(2x +7x - 5 )
Answers
Answer:
x = 15/27
Step-by-step explanation:
3(2x + 7x - 5)
Distribute the 3
6x + 21x - 15
Combine like terms
27x - 15 = 0
27x = 15
x = 15/27
Answer:
27x - 15 is your expression
Step-by-step explanation:
3 x 2x = 6x and 3 x 7x = 21x so 21x + 6x = 27x and 3 x 5 = 15 so 27x - 15 is your expression
