Answer:

Therefore the latitude closest to the equator is 6.49°(approx).

Step-by-step explanation:

Given the path of a solar ellipse is modeled by

f(t)=0.00223t^2-0.558t+41.395

where f(t) is the latitude in degrees south of the equator at t minutes.

We know that ,

The minimum or maximum value of a function y(t) =at²+bt+c

is when t=-\frac{b}{2a}

In this case a= 0.00223, b= - 0.558  and c= 41.395.

The minimum value of f(t)

when t=-\frac{( - 0.558)}{2\times  0.00223}

           =125.11

Therefore the latitude closest to the equator is

f(125.11)=0.00223(125.11)²-0.558×125.11+41.395

            ≈6.49

Craig ran the first part of a race with an average speed of 8 miles per hour and biked the second part of a race with an average
lutik1710 [3]
Let the distance of the first part of the race be x, and that of the second part, 15 - x, then
x/8 + (15 - x)/20 = 1.125
5x + 2(15 - x) = 40 x 1.125
5x + 30 - 2x = 45
3x = 45 - 30 = 15
x = 15/3 = 5

Therefore, the distance of the first part of the race is 5 miles and the time is 5/8 = 0.625 hours or 37.5 minutes
The distance of the second part of the race is 15 - 5 = 10 miles and the time is 1.125 - 0.625 = 0.5 hours or 30 minutes.

Answer:

A: 6x⁸y⁵

B: 4x⁵z⁸

C: 48a¹²b⁵

D: 6s⁹t³

Step-by-step explanation:

When you multiply 2 exponents together, you add them. When you power an exponent, you multiply the 2 exponents together,

3x²2y⁴(2x⁶y)

6x⁸y⁵

xz³(4x⁴z⁵)

4x⁵z⁸

(4a³)²(3a⁶b⁵)

16a⁶(3a⁶b⁵)
