Answer:
-35, 1493
Step-by-step explanation:
p(x) = 2x⁴ + 3x³ - 9x² + 16x + 13
p(-3) = 2(-3⁴) + 3(-3³) - 9(-3²) + 16(-3) + 13
-3² = 9
-3³ = -27
-3⁴ = 81
p(-3) = 2(81) + 3(-27) -9(9) - 48 + 13
p(-3) = 162 - 81 - 81 -48 + 13
81 + 81 = 162 therefore 162 - 81 - 81 cancels
-48 + 13 = -35
p(5) = 2(5⁴) + 3(5³) - 9(5²) + 16(5) + 13
5² = 25
5³ = 125
5⁴ = 625
p(5) = 2(625) + 3(125) - 9(25) + 80 + 13
p(5) = 1250 + 375 - 225 + 93
p(5) = 1250 + 150 + 93
p(5) = 1493
Answer:
A system of the equation of a circle and a linear equation
A system of the equation of a parabola and a linear equation
Step-by-step explanation:
Let us verify our answer
A system of the equation of a circle and a linear equation
Let an equation of a circle as 
..........(1)
Let a liner equation Y = x ............(2)
substitute (2) in (1)
so Y = 
so the two solution are ( 
)
A system of the equation of a parabola and a linear equation
Let equation of Parabola be 
and linear equation y = x
substitute
Y = 0,1
so the two solutions will be (0,0) and (1,1)
Answer:
456 miles
Step-by-step explanation:
We can use proportions to solve
342 miles x miles
------------ = --------------
6 hours 8 hours
Using cross products
342 * 8 = 6x
2736 = 6x
Divide by 6
2736/6 = x
456 miles
It's probably 7:59 because 59 and 7
