Answer:
The point is P(2,7)
Step-by-step explanation:
We are given the following information in the question:
A point is located in the quadrant 1 in the following manner:
It has x-value that is 2 units from the origin.
It has a y-value 7 units from the origin.
Thus, the point is (2,7)
The attached image shows the marked point (2,7).
this makes no sense so maybe try something better
Discriminant, D = b² - 4ac
x² - 4x + 5 = 0 comparing to ax² + bx + c = 0
a = 1, b = -4, c = 5
D = b² - 4ac = (-4)² - 4*1*5 = 16 - 20 = -4
In taking the square root of the discriminant of -4, √-4 = 2i = Not Real. So:
Discriminant is -4, so the equation has no real roots.
The second option is correct.
Answer:
d. V = π(x^3 + 90x^2 + 2,400x + 20,000)
Step-by-step explanation:
volume of cylinder = πr^2h
We have r = x + 20; h = x + 50
V = π(x + 20)^2(x + 50)
V = π(x^2 + 40x + 400)(x + 50)
V = π(x^3 + 50x^2 + 40x^2 + 2000x + 400x + 20,000)
V = π(x^3 + 90x^2 + 2,400x + 20,000)
Answer:
n = (7/3)t
Step-by-step explanation:
Represente the unknown number by n. Then write the statement symbolically, as:
(3/7)n = t
and then solve the above equation for n by multiplying both sides by (7/3):
n = (7/3)t
