A comet is about 7.63 × 103 miles from Earth. Write this number in standard form.

Simora [160]

Answer:

7630

Step-by-step explanation:

We have that the distance of a comet from Earth is about 7.63*10³ .

This number is given in scientific notation.

We want to write this number in standard form.

Since we are multiplying by a power of 10, we move forward three times.

Therefore in standard form:

$7.63 \times {10}^{3} = 7630$

Let f(x) be a continuous function such that f(1) and f'(x)-Vx3 + 6. What is the value of,f(5)? (A) 11.446 (C) 24.672 (B) 13.446

tia_tia [17]

Answer:

f(5) = 26.672 which is option D

Step-by-step explanation:

From question, f(1) = 2 and f'(x)=√(x^3 + 6)

f(5) = f(1) + (5,1)∫ f'(x) dx

Integrating using the boundary 5 and 1;

f(5) = 2 + (5,1)∫√(x^3 + 6) dx

f(5) = 2 + 24.672

So f(5) = 26.672
