JL/LK = sin(30°)
JL = LK*sin(30°) = (8√2)*(1/2) = 4√2

LM/JL = sin(45°)
LM = JL*sin(45°) = (4√2)*(1/√2) = 4

x = LM = 4

Does the function below represent a linear function, an exponential function, a quadratic function, or none of these?
Butoxors [25]

The equation of the function given as (x)= 5 * 2^x is an exponential function

<h3>How to determine the function type?</h3>

The equation of the function is given as

f(x)= 5 * 2^x

An exponential function is represented as

f(x) = a * b^x

Where

Initial value = a

Rate = b

This means that

a = 5

b = 2

Hence, the equation of the function given as (x)= 5 * 2^x is an exponential function

lakkis [162]

Answer:

No

Step-by-step explanation:

Laura painted her room with pink paint that was made by mixing paint at a ratio of 5 parts white paint to 2 parts red paint.

Suppose Laura has 15 parts of white paint. This is thrice the amount Laura needs (because 15:5=3), so she has to have

2\cdot 3=6

parts of red paint.

Hence, if Laura combines 15 parts white and 3 parts red paint, then she will not create the same shade of pink as she used.

Please explain I really need help
velikii [3]

Answer:

1. 1343 years

2. 9 hours

3. 39 years

Step-by-step explanation:

1. Given, half-life of carbon = 5730 years.

∴ λ = 0.693/half-life of carbon = 0.693/5730 = 0.000121

If N₀ = 100 then N = 85

Formula:- N = N₀*e^(-λt)

∴ 85 = 100 * e^(-0.000121t)

∴㏑(-0.85)=-0.000121t

∴ t = 1343 years

2. Given half-life of aspirin = 12 hours

λ = 0.693/12 = 0.5775

Also N₀ = 100 then 70 will disintegrate and N = 30 will remain disintegrated.

∴ 70 = 100 *e^(-0.05775t)

0.70 = e^(-0.05775t)

㏑(0.70) = -0.05775t

∴ t = 9 hours

3.  The population of the birds as as A=A₀*e^(kt)

Given that the population of birds fell from 1400 from 1000, We are asked how much time it will take for the population to drop below 100, let that be x years.

The population is 1400 when f = 0, And it is 1000 when f = 5

We can write the following equation :

1400 = 1000e^(5t).

∴1400/1000 = e^(5k)

∴ k = ㏑(1.4)/5

We need to find x such that 1400/100 = e^(xk)

14 = e^(xk)

∴ x = 39 years

Angie, a student in an advanced statistics course, was given an algebra test and she scored 80%. Is this an accurate predictor o
Zina [86]

Answer:

No

Step-by-step explanation:

She is a way higher level of math and the math she is in is not algebra. However we can assume that the regular algebra students will do worse as statistics is a lot harder than algebra.
