The radius of Earth is 6378.1 km,
which is 2981.1 km longer than the radius of Mars.
The radius of Mars is 3397 km.
Answer:
The correct answer is (-3,-7). This is because you can plug it in and the two sides are equal to each other. When you plug -3 in for x, you subtract for from it and get -7 since the y term is -7 the answer is -7=-7, thus (-3, -7) is the answer.

Step-by-step explanation:
Answer: y= 10(4^x)
Step-by-step explanation:
First, plug in (0,10) to the equation. 10=a*(b^0), since any number to the 0th power equals 1, 10=a*1, or 10=a.
Now, plug in (2,160) to y=10*b^x, or 160=10*b^2. Dividing by 10, 16=b^2, taking the square root, 4=b.
So, 10=a and 4=b, putting those in the equation. y=10(4^x).
1. (x² + 24) factors as the difference of two squares (x² - (-24)) where -24 is the square of the complex number i√24 = 2i√6. The factoring is
(x - 2i√6)(x + 2i√6)
2. The square of half the coefficient of the x-term needs to be added: 4.5² = 20.25
This number goes in both boxes.
3. This is the square of (y² +20), so the factorization is similar to that for problem 1.
y⁴ + 40y² + 400 = (y² + 20)² = (y -2i√5)²(y +2i√5)²
