Answer:
Two angles are complementary angles if the sum of their measures is 908.
Each angle is the complement of the other. Two angles are supplementary
angles if the sum of their measures is 1808. Each angle is the supplement of
the other.
Complementary angles and supplementary angles can be adjacent angles
or nonadjacent angles. Adjacent angles are two angles that share a common
vertex and side, but have no common interior points.

Kailey wrote 8,912,000 in scientific notation as 89.12 times 10 Superscript 5. Which statement best describes Kailey’s work?
Kailey is correct: 89.12 times 10 Superscript 5 equals 8,912,000.
Kailey is not correct: the exponent of ten should be negative.
Kailey is correct: it is written as a decimal number multiplied by a power of ten.
Kailey is not correct: 89.12 times 10 Superscript 5 is not written in scientific notation.
Answers
Answer:
kailey is not correct 89.12 times 10 superscript 5 is not written in scientific notation
Step-by-step explanation:
8.912 times 10 superscript 5 is written is scientific notation
The true statement about Kailey's expression is (a) Kailey is not correct: 89.12 * 10 ^5 is not written in scientific notation.
How to determine the true statement?From the question, Kailey's expression can be represented as:
8,912,000 = 89.12 * 10^5 in scientific notation
To check if Kailey's expression is correct, we count the number of zeros in the number up to 8.9
The number of zero is 6.
So, the scientific notation of the number is
8,912,000 = 8.912 * 10^6
This means that Kailey's expression is not correct
Hence, the true statement is (d)

Write a linear function f with f(-4) = 2 and f(6) =-3
Answers
Answer:
f(x) = - [tex]\frac{1}{2}[/tex] x
Step-by-step explanation:
The standard form for a linear function is
f(x) = ax + b
Using the given values f(- 4) = 2 and f(6) = 3 , then
- 4a + b = 2 → (1)
6a + b = - 3 → (2)
Subtract (2) from (1) term by term to eliminate b
- 10a = 5 ( divide both sides by - 10 )
a = - [tex]\frac{1}{2}[/tex]
Substitute a = - [tex]\frac{1}{2}[/tex] into either of the 2 equations and solve for b
Substituting into (1)
2 + b = 2 ( subtract 2 from both sides )
b = 0
Thus the linear function is
f(x) = - [tex]\frac{1}{2}[/tex] x
The linear function is f(x) = -0.5x
For f(-4) = 2
x₁ = -4, y₁ = 2
For f(6) = -3
x₂ = 6, y₂ = -3
The slope(m) is found using the formula
m = (y₂ - y₁)/(x₂ - x₁)
m = (-3-2)/(6-(-4))
m = -5/10
m = -0.5
Substitute m = -0.5, x₁= -4, and y₁ = 2 into the equation below:
y - y₁ = m(x - x₁)
y - 2 = -0.5(x - (-4))
y - 2 = -0.5(x + 4)
y - 2 = -0.5x - 2
y = -0.5x - 2 + 2
y = -0.5x
Therefore, the linear function is f(x) = -0.5x

Problem 1
Answer: x = 9
----------
Explanation:
For now focus on triangle DEF. We need to find the missing angle D.
D+E+F = 180
D+71+42 = 180
D+113 = 180
D = 180-113
D = 67
In order for DE to be parallel to GH, the alternate interior angles EDF and GHF must be congruent
Let's see what happens when we force them to be equal
angle EDF = angle GHF
67 = 5x+22
67-22 = 5x
45 = 5x
5x = 45
x = 45/5
x = 9

Problem 2
Answers:
Converse: "if it is winter, then it is snowing"
Inverse: "If it is not snowing, then it is not winter"
Contrapositive: "If it is not winter, then it is not snowing"
----------
Explanation:
The original conditional is in the form "If P, then Q". The P and Q are placeholders for logical statements.
We then have the following forms
converse = "if Q, then P" (swap P and Q)inverse = "If not P, then not Q" (negate each)contrapositive = "If not Q, then not P" (do both inverse and converse operations)==========================================
Problem 3
Answer: choice B) "If the sum of two angles is not 180 degrees, then they aren't supplementary"
----------
Explanation:
Refer to problem 2 for the general form of the inverse. We negate each of the P and Q to get our final answer.
==========================================
Problem 4
Answer: Choice C) "If I do not need an umbrella, then it is not raining"

6.4 x 102 km
64 x 102 km
6.4 x 103 km
6.4 x 105 km
Answers
Answer:
[tex] 6.4 * 10^{3} km[/tex]
Step-by-step explanation:
Scientific notation can be defined as a way of expressing and writing a very small or large real number in decimal form. Generally, to use the scientific notation, we will multiply the real number by a power of 10.
Given that the length of Amazon River is 6,400 kilometers.
[tex] \frac{6400}{1000} = 6.4[/tex]
[tex] 1000 = 10^{3}[/tex]
Therefore,
6, 400 kilometers = 6.4 × 10³ kilometers.
