For the first, the initial value is found by finding y when x=0
When x=0
y=4 so the initial value is 4, making your answer
B. 4

For the second one take any two points and do y2-y1/x2-x1
We'll use points 0,0 and 1,3
3-0= 3
1-0=1
So the equation is 3/1x and there's no y intercept
So your answer is
D. y=3x

The speed of the motor boat is 62mph
So your answer is
A.62 miles per hour

The fixed amount is the same as the y intercept, so when x is 0
Y is 8
So your answer is B.$8

Is the power produced directly proportional to the wind speed, give reasons for your answer?

yuradex [85]

Answer:

Is the power produced directly proportional to the wind speed.

No.

A proportional function can be described as y = a * x

So (0, 0) is on the graph, not (3, 0).

0 / 3 = 0

3800/6 = 633.33

7600/9 = 844.44

13600/12 = 1133.33

The quotient y/x should be always the same.

A pole casts a 6-foot shadow. If the distance from the top of the pole to the tip of the shadow is

KATRIN_1 [288]

Answer:

8feet high

Step-by-step explanation:

To get the height of the pole, we will use the pythagoras theorem. Let H be the height

H² = 10² -6²

H² = 100 - 36

H² = 64

H = √64

H = 8feet

Hence the pole is 8feet high

Each unit on the grid stands for one miles determine two ways to calculate the distance from josie's house to annies

Novosadov [1.4K]

I encountered this problem before but it had an accompanying image and list of answer choices.

I'll attach the image and include the list of options.

Each unit on the grid stands for one mile. Determine two ways to calculate the distance from Josie's house to Annie's house.
A) Distance Formula and Slope Formula
B) Midpoint Formula and Slope Formula
C) Distance Formula and Midpoint Formula
<span>D) Distance Formula and Pythagorean Theorem
</span>
My answer is: D.) Distance formula and Pythagorean Theorem.

When looking at the image, I can visualize a right triangle. I'll simply get the measure of the long and short legs and solve for the hypotenuse.
Since the distance formula is derived from the Pythagorean theorem, it can be used to determine the distance from Josie's house to Annie's house.

If 8 times a number is added to twice the number, the result is 60. the solution is

Andrei [34K]

Answer:

(8 * x) + 2x = 60

8x + 2x = 60

10x = 60

/10 /10

x = 6

8 is a constant that is being multiplied by an unknown number which we will name x. It is then being added to two times the unknown number(x), so we multiply x by 2, which is 2x. The final product will be 60, so in the equation it'll then equal 60.

We consider "a number" to be a variable that withholds an unknown value, which is x (or any other variable you prefer).
