1. 2 real solutions
2. no real solutions
3. 2 real solutions
4. 1 real solution
Step-by-step explanation:
The 'solution' to a quadratic equation means the x - intercepts of a graph, so how many times the parabola crosses the x-axis.
ANSWER

EXPLANATION
The given series is

The first term of the series is,

The common ratio of this series is,

This simplifies to,

The sum to infinity of this sequence is given by the formula,

We substitute the above values into the formula to obtain,

This simplifies to,

We simplify the denominator to get,

This will finally give us,


The correct answer is A.
Answer:
32 1/3 or 2/6
Step-by-step explanation:
but 1/3 is better
Answer:
45 degrees
Step-by-step explanation:
Since we have a right triangle, we use the appropriate trigonometric ratio
The angle marked P faces QR and that makes it the opposite side
PR faces the right angle and that makes it the hypotenuse
The trigonometric ratio that links the opposite and the hypotenuse is the sine
It is the ratio of the opposite to the hypotenuse
Thus;
sin P = √26/2 √13
Sin P = √2/2
P = arc sin √2/2
P = 45 degrees
It's along the number line
