Judging by the question I generated the equation y=75(1.09^x)
x is the amount of years.
So the equation you should get for 10 years is y=75(1.09^10)
The answer you get should get is $177.55
Correct answer is the 3rd one.
You have to use distributive property then you combine like terms
Answer:
False
Step-by-step explanation:
We first write the equation in the form ax² + bx + c=0 which gives us:
3x² - 6x + 9=0
Given the quadratic formula,
x= [-b ±√(b²- 4ac)]/2a ,the discriminant proves whether the equation has real roots or not.
The discriminant, which is the value under the root sign, may either be positive, negative or zero.
Positive discriminant- the equation has two real roots
Negative discriminant- the equation has no real roots
Zero discriminant - The equation has two repeated roots.
In the provided equation, b²-4ac results into:
(-6)²- (4×3×9)
=36-108
= -72
The result is negative therefore the equation has no real solutions.
Answer:
<h2>
3.6° and 86.4°</h2>
Step-by-step explanation:
24x - measure of an angle
x - the measure of a complementary angle
Complementary angles adds to 90°
x + 24x = 90°
25x = 90°
x = 90°÷25
x = 3.6°
24x = 24·3.6° = 86.4°
