Answer 1

Answers:

Graph A is a function

Graph B is not a function

========================================================

Explanation:

To check if we have function or not, we apply the vertical line test. This test is where you ask yourself: "Is it possible to draw a single vertical line through more than one point on the curve?"

If the answer to that question is "yes it is possible", then we do not have a function. Graph B shows that we can draw a line through say x = 2 and have the vertical line intersect at points (2,2) and (2,4). The input x = 2 leads to multiple outputs y = 2 and y = 4 simultaneously. This is why graph B is not a function.

A function is only possible when any x input from the domain leads to exactly one y output in the range. Graph A is a function because we cannot draw a single vertical line to intersect through that curve more than once.

Step-by-step explanation:

First, outside, inside, last.

w*w

6*w

9*w

9*6

[tex]w^2+15w+54[/tex]

Answer: w^2 + 15w + 54

Step-by-step explanation:

FOIL = first, outside, inside, last.

First —> multiply first numbers of each parentheses.

Outside —> multiple the OUTSIDE numbers in each parentheses (first number in the first parentheses, second number in the second parentheses.

Inside —> multiply the INSIDE numbers in each parentheses (the second number in the first parentheses, first number in the second parentheses).

Last —> multiply second number of each parentheses.

(W + 9)(w + 6)

F = w^2

O = 6w

I = 9w

L = 54

W^2 + 6w + 9w + 54

W^2 +15w + 54

The distance from Charles's house to his school is 3 miles. His father gave him a ride for 1,760 yards, and he walked the rest of the way. The distance that Charles walked is miles or yards. (Hint: 1 mile = 1,760 yards.)

Answers

Answer:

2 miles or 3520 yards

Step-by-step explanation:

The distance from Charles's house to his school is 3 miles. His father gave him a ride for 1,760 yards, and he walked the rest of the way. The distance that Charles walked is miles or yards. (Hint: 1 mile = 1,760 yards.)

From the Question, we know that

1 mile = 1,760 yards..

His father gave him a ride for 1,760 yards,

Hence, the number of miles Charle's father drove him was 1 mile

The distance that Charles walked in miles is calculated as:

3 miles - 1 mile

= 2 miles

Converting to yards

1 mile = 1,760 yards..

2 miles = x

Cross Multiply

x = 2 × 1760 yards

= 3520 yards

A village is 10km on a bearing 050° from a point O. Calculate how far the village is north of O.

Answers

Answer:

7.66 km

Step-by-step explanation:

Let distance village is ; north of O = x

Using Pythagoras rule :

Sinθ = opposite / hypotenus

Opposite = x

Hypotenus = 10

θ = 50°

Sin50 = x / 10

0.7660444 = x / 10

x = 0.7660444 * 10

x = 7.6604444

x = 7.66

Find a and b

Take LCM

[tex]\frac{x^2 + ax - 4+x + b}{x + 2} = x + 1[/tex]

Cross Multiply

[tex]x^2 + ax - 4+x + b = (x+2)*(x + 1)[/tex]

Open brackets

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 11 feet cubed.

A sphere with height h and radius r. A cylinder with height h and radius r.

Which equation gives the volume of the sphere?
V = four-thirds (11) pi
V = two-thirds (11) pi
V = four-thirds (11)
V = two-thirds (11)

Answers

9514 1404 393

Answer:

  V = (2/3)(11)

Step-by-step explanation:

The given cylinder has a height of 2r, so its volume is ...

  V = πr²(2r) = 2πr³

The volume of a sphere is given by ...

  V = 4/3πr³

Then the ratio of the volume of the sphere to the volume of the cylinder is ...

  (4/3πr³)/(2πr³) = (4/3)/2 = 2/3

So, the volume of the sphere is 2/3 times the volume of the cylinder:

  V = (2/3)(11)
