Answer:
220°
Step-by-step explanation:
If you were to draw a line from points J and L to the center of the circle and call the center point O, angle JOL would be twice as much as angle JKL which is 140° according to a circle law. Since arc JL is 140°, arc JKL would be 220°, as an entire circle is 360°.

(2t2 - 36t + 162). - (t-9)
Answers
Answer:
2t^2 - 37t + 171
Step-by-step explanation:
distrube the - to the (t-9) and then combine like terms
Answer:(2t2 + 27t) - 162 = 0
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 2t2+27t-162
The first term is, 2t2 its coefficient is 2 .
The middle term is, +27t its coefficient is 27 .
The last term, "the constant", is -162
Step-1 : Multiply the coefficient of the first term by the constant 2 • -162 = -324
Step-2 : Find two factors of -324 whose sum equals the coefficient of the middle term, which is 27 .
-324 + 1 = -323
-162 + 2 = -160
-108 + 3 = -105
-81 + 4 = -77
-54 + 6 = -48
-36 + 9 = -27
-27 + 12 = -15
-18 + 18 = 0
-12 + 27 = 15
-9 + 36 = 27 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and 36
2t2 - 9t + 36t - 162
Step-4 : Add up the first 2 terms, pulling out like factors :
t • (2t-9)
Add up the last 2 terms, pulling out common factors :
18 • (2t-9)
Step-5 : Add up the four terms of step 4 :
(t+18) • (2t-9)
Which is the desired factorization
Equation at the end of step
2
:
(2t - 9) • (t + 18) = 0

Theory - Roots of a product
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.

Use complete sentences to answer the following question.
1. Choose one of the properties of exponents (for example, the Power of a Power Rule). Explain how the property works, and provide an example of the property.
Answers
Answer:
Product of a Power: When you multiply exponentials with the same base, you add their exponents (or powers). Power to a Power: When you have a power to a power, you multiply the exponents (or powers). Quotient of Powers: When you divide exponentials with the same base, you subtract the exponents (or powers).
Step-by-step explanation:
Answer:
What is the Power rule?
The Power rule tells us how to differentiate expressions of the form x^nx
n
x, start superscript, n, end superscript (in other words, expressions with xxx raised to any power):
\dfrac{d}{dx}x^n=n\cdot x^{n-1}
dx
d
x
n
=n⋅x
n−1
start fraction, d, divided by, d, x, end fraction, x, start superscript, n, end superscript, equals, n, dot, x, start superscript, n, minus, 1, end superscript
Basically, you take the power and multiply it by the expression, then you reduce the power by 111.
Example: What is the derivative of x2 ?
For x2 we use the Power Rule with n=2:
The derivative of x2 = 2x(2-1)
= 2x1
= 2x
Answer: the derivative of x2 is 2x
