Mike travelled 16 + 30 = 46 miles.

To find how far Henry travelled we use the Pythagoras Theorem

x^2 = 30^2 + 16^2 = 1156

x = sqrt 1156 = 34 miles

Therefore the answer is 46 - 34 = 12 miles

Mike travelled 12 more miles than Henry.

Round of 389,422 in 1,000
Katen [24]
So,

To round the nearest thousand, look at the number in the hundredths place.
If n ≥ 5, round up
If n < 5, round down

4 < 5, therefore round down.

Felix earns $450 per week plus 3% of sales over $4800. Felix’s sales are $53000. How much does Felix earn?
Leni [432]

1.  Felix’s sales are $53000. He has 3% of sales over $4800, then he has 3% of sales $(53000-4800)=$48200.

Now

$48200 -- 100%

$x -- 3%.

Write a proportion:

\dfrac{48200}{x}=\dfrac{100}{3},\\ \\x=\dfrac{48200\cdot 3}{100}=482\cdot 3=1446.

Thus, he additionally gets $1446.

2. If he earns $450 per week and earns $1446 of sales, then Felix earns

$450+$1446=$1896.

Answer: correct choice is A

How you do this?? I don’t get it at allll
Sidana [21]

The values are 5i, -4, 2√2i, -16, -50i and i.

<h3>What is an imaginary number?</h3>

An imaginary number is a number that, when squared, has a negative result, and is defined by its property i² = −1 or i = √-1.

Given are numbers,

1) √-25 = √25*√-1 = 5i

2) √-2√-2 = 2i*2i = 4i² = -4

3) √-8 = √8*√-1 = 2√2i

4) (4i)² = 16*i² = -16

5) (2i)(5i)² = 2i*25i² = 50i³ = -50i

6) i²*i³*i^{4} = -1*(-i)*1 = i

Hence, The values are 5i, -4, 2√2i, -16, -50i and i.

Write the composite function in the form f(g(x)). [Identify the inner function u = g(x) and the outer function y = f(u).] y = ta
Irina-Kira [14]

Answer:

The inner function is u = \pi x.

The outer function is f(u) = \tan{u}.

\frac{dy}{dx} = y^{\prime} = \sec^{2}(u)*\pi = \pi\sec^{2}{\pi x}

Step-by-step explanation:

The inner function is the one we apply the outer function to.

So

y = \tan{\pi x}

We apply the outer function tangent to \pi x.

So, the inner function is u = \pi x.

The outer function is f(u) = \tan{u}.

The derivative of a compositve function

y = f(u) in which u = g(x) is given by the following function.

y^{\prime} = f^{\prime}(u)*g^{\prime}(x)

So

f(u) = \tan{u}

f^{\prime}(u) = \sec^{2}{u}

u = g(x) = \pi x

g^{\prime}(x) = \pi

So

y^{\prime} = f^{\prime}(u)*g^{\prime}(x)

\frac{dy}{dx} = y^{\prime} = \sec^{2}(u)*\pi = \pi\sec^{2}{\pi x}
