Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y=38(1.108)^x
Answers
Step-by-step explanation:
We are given this function:
y=8700* (1.04)^{4}y=8700∗(1.04)
4
8700 is the initial amount.
1.04 shows the change of original amount. This is decimal form of percentage. We need to transform it into regular percentage.
1.04 * 100% = 104%
Now we observe this number. If it is greater than 100% we have growth, if it is lower than 100% it is decay, and if it is equal to 100% than there is no change.
In our case this number is greater than 100% so we have growth. To determine the percentage rate we must substract 100% as it represents the original amount.
104% - 100% = 4%
This would be our solution if we don't have an exponent.
We have exponent so first step is to calculate the number and then we repeat the steps from above.
1.04^{4} = 1,169858561.04
4
=1,16985856
1,16985856 * 100% ≈ 116,99%
116.99% - 100% = 16.99%
So, final solution is growth of 16.99%

Step-by-step explanation:
Hey There!
So if you didn't know angle H is a right angle. So we are given two angles and they want us to find the missing angle
Remember all of the angles of a triangle add up to equal 180
so we subtract the given angles from 180 to find the missing angle
180-90-68=22
so we can conclude that angle G = 22

When it ask for the scale factor its asking for what did you have to multiply the side length by of figure a to get the similar side length of figure b
for example in figure A the base length is 7
to get the the base length of figure B (14) they multiplied the base length of figure A by 2
7x2=14
therefore the scale factor is 2

A metre stick is left outside in the sun and it expands. Explain how this will affect the sticks accuracy and precision. I'm just confused what they mean by the question lol The stick?? Expands???
Answers
Answer:
The expansion of a metre stick (also known as meter stick) in the Sun will affect the meters stick accuracy by reducing the values of the actual length of the dimensions measured with the meter stick
The linear expansion, ΔL, of the meter stick is given according to the following formula;
ΔL = ∝·L₀·ΔT
Where;
ΔL = The expansion (change in length) of the meter stick
∝ = The coefficient of linear expansion for the meter stick
L₀ = The initial length of the meter stick = 1 meter
ΔT = The temperature change of the meter stick
Due to the small value of ∝ for a meter stick, the change in length of the meter stick is small but the difference will affect the accuracy of the measurements made by the meter stick and the length of an item with actual length of 1 meter can be given by the expanded meter stick as 99 cm
