Answer:
-1.0, 1.0
Step-by-step explanation:
The given polynomial function is
f(x) = 2 {x}^{4} - {x}^{3} + x - 2
According to the Rational Roots Theorem, the possible roots of this function are;
\pm1,\pm \frac{1}{2}
We now use the Remainder Theorem to obtain;
f(1) = 2 {(1)}^{4} - {(1)}^{3} + 1 - 2
f(1) = 2 - 1+ 1 - 2 = 0
f( - 1) = 2 {( - 1)}^{4} - {( - 1)}^{3} - 1 - 2
f( - 1) = 2 + 1 - 1 - 2 = 0
But;
f( \frac{1}{2} ) = - 1.5
f( - \frac{1}{2} ) = - 2.25
Since f(1)=0 and f(-1)=0, the real zeros to the nearest tenth are:
-1.0 and 1.0
ANSWER: 1, 16, 100 are perfect squares.
STEP-BY-STEP EXPLANATION:
A perfect square is a number that can be expressed as the product of two equal integers.
1 x 1 = 1
4 x 4 = 16
10 x 10 = 100
Answer:
<em>conclusion : Life expectancy of women > Life expectancy of men </em>
Step-by-step explanation:
A) Mean life expectancy of women
from the attached table
mean life expectancy of women = ∑fx / ∑f
∑fx = 1523
∑f = 20
mean = 1523 / 20 = 76.15
The line graph shows a negatively skewed distribution
B) Mean life expectancy of Men
from the attached table
mean life expectancy of Men = ∑fx / ∑f
∑fx = 1432
∑f = 20
mean = 1432 / 20 = 71.6
<em>conclusion : Life expectancy of women > Life expectancy of men </em>
Answer:
B, C, F
Step-by-step explanation:
Took this quiz got it right
You have to create and equivalent EXPRESSION in the equation that have equal bases then solve for x
SO THE ANSWER IS 12<span />
