Answer:
He can grade 1.25 assignments in 1 minute.
Step-by-step explanation:
Because the teacher can grade 25 assignments in 20 minutes, we can dive 25 by 20 to get the constant rate.
So he can grade 1.25 assignments in 1 minute.
Answer:
y = |x-3| -1
Step-by-step explanation:
The parent function has been shifted right 3 units and down 1 unit. That is f(x)=|x| has been moved to ...
y = f(x -3) -1
y = |x -3| -1 . . . . matches the last choice
If the discriminant, b² - 4ac is<u> positive</u>
<h3>How to complete the statement?</h3>
From the question, we have the following equation of discriminant
The discriminant (d) is calculated as
d = b² - 4ac
The solutions of a quadratic equation are dependent on the following conditions
- If d = 0, the quadratic equation has 1 real solution
- If d < 0, the quadratic equation has imaginary solutions
- If d > 0, the quadratic equation has 2 different real solutions
This means that "d > 0, the quadratic equation has 2 different real solutions" implies that the discriminant is positive
Hence, the complete statement is (b) positive

Answer:
7 (7.07106781187)
Step-by-step explanation:
All you have to do is find the diameter of the rectangle from two farthest corners. To do this, use the Pythagorean Theorem
(5^2) + (5^2) = c^2
25 + 25 = c^2
50 = c^2
7 ≈ c
Answer: C) 9/41
Step-by-step explanation: From the description, angle S is the right angle. Which means that angles T and R are complementary (they sum to 90 degrees). Because they are complementary, this means the cosine of one angle is equal to the sine of the other angle. If cos(T) is 9/41, then so is sin(R).
