Answer: See explanation.
Step-by-step explanation:
You need to put a little X on the graph down at the bottom on the ticks that represent 1/2, 3/4, 1 1/4, and 2.
Answer:
The answer to your question is: This polynomial does not have root, it does not intercept the x-axis.
Step-by-step explanation:
a)
2x² + 4x + 7
To determine the number of roots of this polinomial, just look at the higher power and that number will be the maximum possible number of roots.
In this exercise, the maximum power is 2, so this polynomial could have at most 2 roots.
b) Find the possible roots of the polynomial, which are multiples of 7
Possible roots: ±1, ±7
2x² + 4x + 7
Use synthetic division to find the roots
2 4 7 1
2 6
2 6 13 +1 is not a root
2 4 7 -1
-2 -2
2 2 5 -1 is not a root
2 4 7 7
14 126
2 18 133 +7 is not a root
2 4 7 -7
-14 70
2 -10 -77 -7 is not a root
Answer:
x = 48°
Step-by-step explanation:
<u />
<u>Complementary angles</u>
Angles that sum to 90°.
<u />
<u>Vertical Angle Theorem</u>
When two straight lines intersect, the vertical angles are congruent (equal).
Therefore, angle x is equal to the angle that is complementary to 42°.
To find x, subtract 42° from 90°:
⇒ x = 90° - 42°
⇒ x = 48°
So:
1000 meters = 1 kilometer,
So we can use the ratio 1km/1000m
Thus,
.007 kilometers*(1000m/1km) = 7 meters
So the equation is:
.007 kilometers = 7 meters
or
.007km = 7m
