Answer:
Your solution would be -1x^4 - 1x^3 + x^2 - 6x - 6.
Step-by-step explanation:
Answer:
#7000, #14000 and #28000 respectively
Step-by-step explanation:
#49000 to be shared in 1:2:4
49000 ÷ (1 + 2 + 4) = 49000/7 = #7000
A will get (7000×1) = #7000
B will get (7000×2) = #14000
C will get (7000×4) = #28000
Answer:
The proportion would be 0.1
Step-by-step explanation:
Given, the function that shows the proportion of students in a psychology experiment who could remember an eight-digit number correctly for t minutes,

If t = 7 minutes,

Hence, the proportion that remembered the number for 7 minutes is 0.1 ( approx )
They forget to say "not to scale". I'm guessing this is trig because I don't see another way to do it.
Let's consider x=chord PQ first. By the Law of Cosines

We have an isosceles triangle formed by two radii of 9 cm and x=PQ. By the Law of Cosines again,





The area of the circle is the fraction given by the angle,



Answer: 24.7 sq cm
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 4
