<h2>Answer:</h2>

The value of $f(x)=\log 4x$ as x approaches +∞ is:

f(x) → ∞

<h2>Step-by-step explanation:</h2>

We are given a logarithmic function f(x) as:

$f(x)=\log 4x$

We know that the logarithmic function $\log x$ is defined for x>0 and the graph of the function increases continuously and goes or tends to infinity as x tends to infinity.

Hence, here also if x → ∞

then f(x) → ∞

Also it could be seen with the help of the graph of the function f(x)

If 800g of a radioactive substance are present initially and 8 years later only 450g remain, how much of the substance will be p

artcher [175]

A=Pe^(rt)

P = 800g

t = 8 years

A = 450g

r = This is what we will try and find to start with

450=800e^(r*8)

After running the math through a calculator, we end with r = -0.07192

Now we just re-input this information into our equation: A=800e^(-0.07192*16)

A=800e^(1.15072)

Now we will re-write the equation using the negative exponent rule:

A = 800 1/e^1.15072

Combine right side:

A = 800/e^1.15072

Then do the math:

A = 253.12709836......

That will give us A = 253 (rounded to the whole number)

I hope this helps! :)

Complementary and

Answer:

$\boxed{\boxed{\sf x=42\°}}$

Step-by-step explanation:

Given the diagram, we can see that ∠PQR and ∠RQS are complementary angles.

*Two angles with measures that add up to 90° are known as Complementary angles.*

Therefore, m∠PQR+m∠RQS=90°

$\sf \angle PQR+\angle RQS=90\°$

$\sf 48+x=90\°$

Subtract 48 from both sides:

$\sf 48+x-48=90-48$

$\sf x=42\°$
