Answer:

One point

Step-by-step explanation:

Given information: line d intersects plane f.

Plane: In mathematics, a flat, 2D surface that extends infinitely far is know as plane.

Line: A line of infinite number of points that extends infinitely in two directions is know as line.

In 3D, a line can be parallel to the plane, lie on the plane and intersect then plane.

(a) If line is parallel, then no point on the line lie on the plane.

(b) If line is on the plane, then infinite points on the line also lie on the plane.

It is given that line d intersects plane f.

If line d intersects plane f, then only 1 one point on line d also lie on plane f.

I really need help!! (can you show step by step guide? (

Answer:

Look below

Step-by-step explanation:

(i) Sharon is not correct because in the first bag, the proportion is of red counters to yellow counters.

In the second bag, the proportion is of red counters to all the counters in the bag. Therefore the proportions are not the same.

(ii) Let x be the total amount of counters (in each bag)...

Then the amount of red counters would be

$\frac{1}{5} x$

And the amount of yellow counters would be

$\frac{4}{5} x$

For the second bag, the amount of red counters would be

$\frac{1}{4} x$

And the amount of yellow counters would be

$\frac{3}{4} x$

What is the y-intercept of the line y + 11 = –2(x + 1.5)? y-intercept =

Lana71 [14]

y + 11 = –2(x + 1.5)

y=mx+b

multiply the bracket by -2

(-2)(x)=-2x

(-2)(1.5)=-3

y+11=-2x-3

move +11 to the other side

sign changes from +11 to -11

y+11-11=-2x-3-11

y=-2x-14

m is also the slope

b= y-intercept

Answer:

y-intercept=-14

15. The average speed that a tsunami (a large tidal wave) travels is represented

irina [24]

Correct question :

The average speed that a tsunami (a large tidal wave) travels is represented

by the function $s = (200d)^1^/^2$ where s is the speed (in miles per hour) that the tsunami is traveling and d is the average depth (in feet) of the wave.

a. Find the inverse of the function.

b. Find the average depth of the tsunami when the recorded speed of the wave is 250 miles per hour.

Answer:

a) $d = \frac{s^2}{200}$

b) 312.5 ft

Step-by-step explanation:

Given:

Average speeds, $s = (200d)^1^/^2$

a) To find the inverse of the function.

$s = (200d)^1^/^2$

s² = 200d

200d = s²

$d = \frac{s^2}{200}$

Therefore, inverse of the function =

$d = \frac{s^2}{200}$

b) average depth when speed is 250 miles per hour.

Average depth = d

Therefore, let's use the formula :

$d = \frac{s^2}{200}$

$= \frac{250^2}{200}$

$= \frac{62500}{200}$

d = 312.5 feet

The average depth when speed is 250 miles per hour is 312.5 ft
