i need help with part a and b. sorry its kind of hard to read

Answers

Answer:

A) 4900

B) How far above she is before she starts hiking/the distance she is from the canyon floor.

Step-by-step explanation:

Since it's linear, it will follow the formula y=mx+c.

We can sub in the values to get:

3500=m(1)+c → 3500-m=c

2100=m(2)+c → 2100 = 2m+c

Sub '3500-m' in for c:

2100=2m+3500-m

m= -1400

c=3500-m=3500-(-1400)=3500+1400=4900

∴equation is: y= -1400x+4900

To find the initial value, ie when the number of hours = 0, we sub in zero for x:

y = -1400(0) + 4900

PART A ANS: 4900

PART B ANS: Since the number of hours passed is zero, the value represents how far above she is before she starts hiking/the distance she is from the canyon floor.

End Behavior

When x approaches negative infinity, f(x) approaches the negative infinity as well.

When x approaches positive infinity, f(x) approaches positive infinity.

Step-by-step explanation:

A five-degree polynomial function. Rearrange the terms.

[tex]y = 3 {x}^{5} + 4 {x}^{3} - {x}^{2} - 2[/tex]

Because it is an odd-degree function, the graph increases from negative infinity and ends by increasing at positive infinity.

Which expressions are equal to
23 ?

Answers

Answer: The first option and the third option

Step-by-step explanation: You are not supposed to find something equivalent to the fraction, you have to divide the fraction.

13824 ÷ 8 = 1728

Then it is when you try to find a number equivalent to 1728. 12 to the power of 3 equals 1728

12×12=144

144×12=1728

12 to the power of 3 is equivalent to 1728

These are wrong: 2 to the power of three is unequivalent and so is 12 to the power of 6 and 6 to the power of 3

2 to the power of 6 is 64

2×2=4

4×2=8

8×2=16

16×2=32

32×2=64

3 to the power of 3 is 27

3×3=9

9×3=27

64 times 27 equals 1728 so it's equivalent and that means that our answers are A, the 1st option , and C, the 3rd option

The equivalent expression will be;

⇒ 12³

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 6³ × 2⁶ / 2³

Now,

Since, The expression is,

⇒ 6³ × 2⁶ / 2³

Solve as;

⇒ 6³ × 2⁶ × 2⁻³

⇒ 6³ × 2⁶⁻³

⇒ 6³ × 2³

⇒ (6 × 2)³

⇒ 12³

Thus, We get;

⇒ 6³ × 2⁶ / 2³ = 12³

Read the excerpt from Heart of a Samurai and then answer the question.

The strangers leaped out of their boats and pulled them up on the small beach. By signs, they made it clear the castaways should climb aboard.

The fishermen exchanged frightened glances and whispered to one another,

“What about Denzo and Jusuke?”

Gesturing, Manjiro communicated to the strangers about the two men in the cave. Denzo and Jusuke were retrieved, both of them so weak they had to be carried to the boats. Everyone found a place and the sailors shoved off. The two boats rowed away from the island toward an unknown future.

The sun flickered on the restless waves just as it always did. The wind blew just as steadily as it always had. Yet everything had changed. They had been rescued from the island, only to be taken captive by barbarians.

Manjiro stared at the strangers when he thought they weren’t looking. Sometimes he caught them staring at him when they thought he wasn’t looking.
What do the details in this excerpt help readers to infer about the barbarians?
A. They are just as mean and monstrous as the fishermen expect them to be.
B. They are suspicious creatures who seem to be from a place other than Earth.
C. They have a plan to humiliate the fishermen and are waiting for the right time.
