Find the domain and range of the exponential function h(x) = –343^x. Explain your findings. As x decreases, does h increase or decrease? Explain. As x increases, does h increase or decrease? Explain.
Answer:
As x decreases, h increases (but never touches)
As x increases, h decreases (but never touches)
Step-by-step explanation:
If you graphed the exponential, you would be able to see that it is stuck in the 3rd quadrant.
Domain: (negative infinity, 1)
Range: (negative infinity, 0)

Which of the following is a geometric sequence?
0, 2, 6, 12, 72, . . .
4, 9, 14, 19, 24, . . .
1, 3, 9, 27, 81,
Answer:
1, 3, 9, 27, 81, is a geometric sequence.
Step-by-step explanation:
A geometric sequence is basically a sequence of numbers that's multiplied by or divided one specific set number each time.
0, 2, 6, 12, 72, does not have a set number it is multiplied or divided by each time.
4, 9, 14, 19, 24, adds 5 each time, it doesn't multiply
Answer:
D - 1, 3, 9, 27, 81, . . .

Which of the following illustrates the associative property of multiplication?
4 × 8 = 8 × 4
2(12 + 3) = 2 × 12 + 2 × 3
9 × (1 × 4) = (9 × 1) × 4
8 × 1 = 8
Answer:
9 × (1 × 4) = (9 × 1) × 4
Step-by-step explanation:
Number 3 because the associative property states that it doesn't matter how you add / multiply something in sets.
9 × (1 × 4) = (9 × 1) × 4 shows 9 × 1 × 4 in 2 ways with 2 sets.
Answer:
9 × (1 × 4) = (9 × 1) × 4 is the answer because it means you can group in any combination
Step-by-step explanation:
9 × (1 × 4) = (9 × 1) × 4

What is the measure of angle TRV?
O 20°
O 50°
60°
O 130°
Answer:
•130°
Step-by-step explanation:
...........…..
The measure of the angle ∠TRV from the intersecting lines is ∠TRV = 130°
What are the angles formed by 2 intersecting lines?Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.
Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.
When lines intersect, two angle relationships are formed:
Opposite angles are congruent
Adjacent angles are supplementary
Given data ,
Let the two intersecting lines be m and n
Now , the linear pair of angles are supplementary or Adjacent angles are supplementary
And , the measure of ∠TRV + ∠TRS = 180°
On simplifying , we get
(x - 10)° + (2x + 10)° = 180°
x - 10 + 2x + 10 = 180°
3x = 180°
x = 60°
Now , the measure of m∠TRV = ( 2x + 10 )°
m∠TRV = 2( 60 ) + 10
m∠TRV = 130°
Hence , the measure of angle ∠TRV = 130°

Answer: B. y = -3x
Step-by-step explanation:
By plugging in the given point into each answer choice for the x and y values for which ever equation is true that is the correct answer.
For the purpose of speeding things up the correct answer is B y = -3x
If we plug in the point give, (1, -3) for (x, y) then we get the equation:
-3 = -3 * 1
This equation when solved: -3 = -3 which is true so this is the correct answer.

mary thinks the triangle is equilateral. how would you support or dispute her conjecture?
Answer:
Use the distance formula to calculate the length of all three sides, and check whether all sides are congruent.
Step-by-step explanation:
An equilateral triangle would have three sides that are all the same length, out of these options, only using the distance formula to calculate the length of all three sides and checking whether they are all congruent will make sure that the triangle is equilateral instead of just isosceles.
Find the next term of the geometric sequence 2/27 , 2/9 , 2/3 , .. Please help
Answer:
2/1 or 2Step-by-step explanation:
They are dividing the denominator by 3. So, the answer is 2/1 or basically the number 2.
For example,
27/3 = 9
9/3 = 3
3/3 = 1The last math shows how I got the answer.
Hope this helps!
Answer:
2

When is written in simplest radical form, which value remains under the radical?
Answer:
The number that is a perfect square remains on the outside and the one that isn't, stays on the inside. For example, you can make the number 2[tex]\sqrt{3}[/tex] only when the number on the outside is a perfect square. The original number was 4, so it reduced down to 2, and the other number stayed in the radical

From the given equation we can immediately discern that the slope of these lines is 4 (as they are parallel).
Starting with the slope-intercept formula y = mx + b, we get:
32 = 4(4) + b, or 16 = b, or y = 4x + 16
