PLEASE HELP IM SO CONFUSED.

Answers

Answer 1
I think c but i’m not to sure..
Answer 2

Answer:

The answer is B.

Step-by-step explanation:

A function means, for every X there is only one Y.

However, it gets confusing because there for every Y, there CAN be two X's. You have to look for the coordinates sharing the same x (ex: (3,6) and (3,7)) and make sure they have the same y. If they don't, it's not a function.

A bicycle tire makes 40 full revolutions while traveling where Scott is standing to where Steve is standing. If a tire has a diameter of 20 inches what is the approximate distance between where Steve is standing?

Answers

Answer:

2513.27 inches

Step-by-step explanation:

Given that:

Diameter = 20 inches

Number of revolutions = 40

For a complete revolution :

Distance traveled = Circumference = 2πr

2 * π * 20/2 = 62.831853 inches

Distance per revolution * number of revolutions

62.831853 * 40

= 2513.2741 inches

= 2513.27 inches

f(x)=x2 + 4x -6
f(x) can be written in the form (x + m)?+n.
Find the value of m and the value of n.​

Answers

Answer:

m = 2 and n = -10

Step-by-step explanation:

The given function is f(x) = x² + 4·x - 6

The form in which f(x) is to be written = (x + m)² + n, which is the standard form of a quadratic equation

We have;

f(x) = x² + 4·x - 6 = x² + 4·x + 4 - 6 - 4

f(x) = x² + 4·x + 4 - 6 - 4 = (x + 2)² - 10

f(x) = (x + 2)² - 10

By comparison with (x + m)² + n, we have;

m = 2, and n = -10

Write an exponential function whose graph passes through
the points (0, -3) and (4, -48)

Answers

Answer:

[tex]y = -3(2^{x})[/tex]

Step-by-step explanation:

y = [tex]kb^{x}[/tex]

Use (0, -3) to find k

[tex]-3 = kb^{0} = k(1) = k\\[/tex]

So, k = -3

Now use (4, -48) to find b

-48 = [tex]-3b^{4}[/tex]

[tex]b^{4}[/tex] = 16

b = 2

Since k = -3 and b = 2,   [tex]y = -3(2^{x})[/tex]

In ΔMNO, m = 780 inches, o = 760 inches and ∠O=164°. Find all possible values of ∠M, to the nearest degree.

Answers

Answer:

So the answer is both

180 and 328 (but it may or may not show you "not possible, if so, then you got it right)

Step-by-step explanation:

SinA/a= SinB/b

1. SinM/780 = Sin164/760

2. 780sin164/760 = 0.2828909704

3. M = sin^-1 (0.2828909704)= 16.4328229 or 16

Check for possibility

180-16= 164

164 + 16= 180 (not possible)

164 + 164= 328 (not possible)

A. plant 3; plant 3


B. plant 1; plant 3


C. plant 2; plant 2


D. plant 3; plant 1

Answers

Answer:

A. plant 3; plant 3

Step-by-step explanation:

Plant 3 was the tallest at the beginning. We know this because it is the plant with the highest recorded height at time = 0.

Plant 1 grew 3.5 inches over 6 weeks.

Plant 2 grew ~ 2.25 inches over 6 weeks.

Plant 3 grew 4 inches over 6 weeks.

> This means that plant 3 grew the most, or had the greatest rate of change, over the 6 weeks.

A man is parasailing on a lake. The rope he is holding is 150 feet long and he is 45 feet above the water. What is the horizontal distance between the man and the boat? Round your answer to the nearest tenth.​

Answers

9514 1404 393

Answer:

  143.1 ft

Step-by-step explanation:

Assuming the rope is tied to the boat, and that the geometry can be modeled by a right triangle, the Pythagorean theorem is helpful.

  150² = 45² + d²

  d = √(150² -45²) = √20475 ≈ 143.1 . . . . feet

The horizontal distance between the man and the boat is about 143.1 feet.

x=-6

hence the point is (-6,0)

ii)5(2)+6y+30=0
