Answer:
A:102
Step-by-step explanation:
We are given that the points A(0,0),B(0,4a-5) and C(2a-+1,2a+6) form a triangle.
If angle ABC=
We have to find the area of triangle ABC
If angle ABC= 90 degree
From given below figure
Substitute the values then we get
B(0,17) and C (12,17)
Distance formula
AB=
BC=
BC=
units
Area of triangle =
Substitute the values
Then we get
Area of triangle ABC=
Area of triangle ABC=102 square units
Answer: A: 102
Answer:
7 years
Step-by-step explanation:
An initial investment of $200 is now valued at $350. The annual interest rate is 8% compounded continuously. The equation represents the situation, where t is the number of years the money has been invested. About how long has the money been invested? Use a calculator and round your answer to the nearest whole number.
A divergence testing just diverts your mind and imagination into several possibilities and scenarios regarding the same issue.
A divergence test will simply test your imagination and forces your mind to go into as many directions as possible.
On the other hand, a converge test will sort of converge your imagination and your mind into a set of possibilities or options.
A convergence test will let you sort between a set of possibilities and decide on the best one.
Answer:
28/9
Step-by-step explanation:
If the roots are J and K, then:
3 (x − J) (x − K) = 0
3 (x² − (J+K)x + JK) = 0
So if we factor out the leading coefficient:
3x² − 2x − 4 = 0
3(x² − 2/3x − 4/3) = 0
The coefficient of the second term is the sum of the roots:
J + K = 2/3
And the constant is the product of the roots:
JK = -4/3
If we take the sum of the roots and square it:
(J + K)² = (2/3)²
J² + 2JK + K² = 4/9
And subtract twice the product:
J² + K² = 4/9 − 2JK
J² + K² = 4/9 − 2(-4/3)
J² + K² = 4/9 + 8/3
J² + k² = 28/9
I believe this is what is wanted
