Answer:
16.2 + (-8.7)
Step-by-step explanation:
16.2 + (-8.7) has the same value since the negative and positive will end up being negative.
1) Volume = π r² h/3
V = 3.14 * (5cm)² * 10cm/3
V = 3.14 * 25cm² * 3.33cm
V = 261.41 cm³
2) M1 = 1,1; N1 = 3, -1 ; O = -2, -3 ; P1 = -2, 2
M2 =3,3 ; N2 = 9, -3 ; O = -6, -9 ; P2 = -6, 6
Point 2 / Point 1
x y
M = 3/1 = 3 ; 3/1 =3
N = 9/3 = 3 ; -3/-1 = 3
O = -6/-2 = 3 ; -9/-3 = 3
P = -6/-2 = 3 ; 6/2 = 3
Answer is A.) (x,y) ⇒ (3x, 3y)
Dear Mgreeneyesd3, the ratios of children to teacher are proportional. 6/24=1/4, so if we do cross products, then we get 24=24.
Check the attached answer.
Without any extra conditions, the answer could be 3, and the simplest polynomial with the given roots would be
(<em>x</em> + 5) (<em>x</em> - (1 + 4<em>i</em> )) (<em>x</em> + 4<em>i</em> )
= <em>x</em> ³ + 4<em>x</em> ² + (11 - 4<em>i</em> ) <em>x</em> + 80 - 2<em>i</em>
<em />
If the polynomial is supposed to have only <em>real</em> coefficients, then any complex roots must occur along with their complex conjugates:
(<em>x</em> + 5) (<em>x</em> - (1 + 4<em>i</em> )) (<em>x</em> - (1 - 4<em>i</em> )) (<em>x</em> + 4<em>i</em> ) (<em>x</em> - 4<em>i </em>)
= <em>x</em> ⁵ + 3<em>x</em> ⁴ + 23<em>x</em> ³ + 133<em>x</em> ² + 112<em>x</em> + 1360
and then the degree would be 5.
